A body of water covering approximately one-fifth of the total ocean area of the earth, extending amidst Africa in the west, Australia in the east, Asia in the north, and Antarctica in the south. Including the Red Sea and the Persian Gulf, it constitutes the third largest ocean after the ATLANTIC OCEAN and the PACIFIC OCEAN. (New Encyclopaedia Britannica Micropaedia, 15th ed, 1990, p289)
Multicellular marine macroalgae including some members of red (RHODOPHYTA), green (CHLOROPHYTA), and brown (PHAEOPHYTA) algae. They are widely distributed in the ocean, occurring from the tide level to considerable depths, free-floating (planktonic) or anchored to the substratum (benthic). They lack a specialized vascular system but take up fluids, nutrients, and gases directly from the water. They contain CHLOROPHYLL and are photosynthetic, but some also contain other light-absorbing pigments. Many are of economic importance as FOOD, fertilizer, AGAR, potash, or source of IODINE.

Oceans and Seas
Flagellate EUKARYOTES, found mainly in the oceans. They are characterized by the presence of transverse and longitudinal flagella which propel the organisms in a rotating manner through the water. Dinoflagellida were formerly members of the class Phytomastigophorea under the old five kingdom paradigm.
The collective name for the islands of the central Pacific Ocean, including the Austral Islands, Cook Islands, Easter Island, HAWAII; NEW ZEALAND; Phoenix Islands, PITCAIRN ISLAND; SAMOA; TONGA; Tuamotu Archipelago, Wake Island, and Wallis and Futuna Islands. Polynesians are of the Caucasoid race, but many are of mixed origin. Polynesia is from the Greek poly, many + nesos, island, with reference to the many islands in the group. (From Webster's New Geographical Dictionary, 1988, p966 & Room, Brewer's Dictionary of Names, 1992, p426)
The phylum of sponges which are sessile, suspension-feeding, multicellular animals that utilize flagellated cells called choanocytes to circulate water. Most are hermaphroditic. They are probably an early evolutionary side branch that gave rise to no other group of animals. Except for about 150 freshwater species, sponges are marine animals. They are a source of ALKALOIDS; STEROLS; and other complex molecules useful in medicine and biological research.
A chain of islands, cays, and reefs in the West Indies, lying southeast of Florida and north of Cuba. It is an independent state, called also the Commonwealth of the Bahamas or the Bahama Islands. The name likely represents the local name Guanahani, itself of uncertain origin. (From Webster's New Geographical Dictionary, 1988, p106 & Room, Brewer's Dictionary of Names, 1992, p45)
One of the three domains of life (the others being BACTERIA and ARCHAEA), also called Eukarya. These are organisms whose cells are enclosed in membranes and possess a nucleus. They comprise almost all multicellular and many unicellular organisms, and are traditionally divided into groups (sometimes called kingdoms) including ANIMALS; PLANTS; FUNGI; and various algae and other taxa that were previously part of the old kingdom Protista.
Any significant change in measures of climate (such as temperature, precipitation, or wind) lasting for an extended period (decades or longer). It may result from natural factors such as changes in the sun's intensity, natural processes within the climate system such as changes in ocean circulation, or human activities.
El Nino-Southern Oscillation
El Nino-Southern Oscillation or ENSO is a cycle of extreme alternating warm El Niño and cold La Nina events which is the dominant year-to-year climate pattern on Earth. Both terms refer to large-scale changes in sea-surface temperature across the eastern tropical Pacific. ENSO is associated with a heightened risk of certain vector-borne diseases.

Former Netherlands overseas territory in the Lesser Antilles in the West Indies. It had included the islands of Aruba, Bonaire, Curacao, Saba, St. Eustatius, and the southern part of St. Martin. The Netherlands Antilles dissolved on October 10, 2010. Aruba, Curacao and Sint Maarten became autonomous territories of the Kingdom of the Netherlands. Bonaire, Saba, and Sint Eustatius are under the direct administration of the Netherlands. (From US Department of State, Background Note)
Plants of the division Rhodophyta, commonly known as red algae, in which the red pigment (PHYCOERYTHRIN) predominates. However, if this pigment is destroyed, the algae can appear purple, brown, green, or yellow. Two important substances found in the cell walls of red algae are AGAR and CARRAGEENAN. Some rhodophyta are notable SEAWEED (macroalgae).
The sequence of transfers of matter and energy from organism to organism in the form of FOOD. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. PLANTS, which convert SOLAR ENERGY to food by PHOTOSYNTHESIS, are the primary food source. In a predator chain, a plant-eating animal is eaten by a larger animal. In a parasite chain, a smaller organism consumes part of a larger host and may itself be parasitized by smaller organisms. In a saprophytic chain, microorganisms live on dead organic matter.
A state in northeastern Australia. Its capital is Brisbane. Its coast was first visited by Captain Cook in 1770 and its first settlement (penal) was located on Moreton Bay in 1824. The name Cooksland was first proposed but honor to Queen Victoria prevailed. (From Webster's New Geographical Dictionary, 1988, p996 & Room, Brewer's Dictionary of Names, 1992, p441)
A mass of organic or inorganic solid fragmented material, or the solid fragment itself, that comes from the weathering of rock and is carried by, suspended in, or dropped by air, water, or ice. It refers also to a mass that is accumulated by any other natural agent and that forms in layers on the earth's surface, such as sand, gravel, silt, mud, fill, or loess. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed, p1689)
An island in Micronesia, east of the Philippines, the largest and southernmost of the Marianas. Its capital is Agana. It was discovered by Magellan in 1521 and occupied by Spain in 1565. They ceded it to the United States in 1898. It is an unincorporated territory of the United States, administered by the Department of the Interior since 1950. The derivation of the name Guam is in dispute. (From Webster's New Geographical Dictionary, 1988, p471)
The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
A group of islands in Polynesia, in the north central Pacific Ocean, comprising eight major and 114 minor islands, largely volcanic and coral. Its capital is Honolulu. It was first reached by Polynesians about 500 A.D. It was discovered and named the Sandwich Islands in 1778 by Captain Cook. The islands were united under the rule of King Kamehameha 1795-1819 and requested annexation to the United States in 1893 when a provisional government was set up. Hawaii was established as a territory in 1900 and admitted as a state in 1959. The name is from the Polynesian Owhyhii, place of the gods, with reference to the two volcanoes Mauna Kea and Mauna Loa, regarded as the abode of the gods. (From Webster's New Geographical Dictionary, 1988, p493 & Room, Brewer's Dictionary of Names, 1992, p2330)
An island in the Lesser Antilles in the West Indies. It is chiefly of coral formation with no good harbors and only small streams. It was probably discovered by the Portuguese in the sixteenth century. The name was given by 16th-century Spanish explorers from barbados, the plural for "bearded", with reference to the beard-like leaves or trails of moss on the trees that grew there in abundance. (From Webster's New Geographical Dictionary, 1988, p116 & Room, Brewer's Dictionary of Names, 1992, p49)
One of the largest genera of BROWN ALGAE, comprised of more than 150 species found in tropical, subtropical, and temperate zones of both hemispheres. Some species are attached (benthic) but most float in the open sea (pelagic). Sargassum provides a critical habitat for hundreds of species of FISHES; TURTLES; and INVERTEBRATES.
The branch of science concerned with the interrelationship of organisms and their ENVIRONMENT, especially as manifested by natural cycles and rhythms, community development and structure, interactions between different kinds of organisms, geographic distributions, and population alterations. (Webster's, 3d ed)
Ecological Parameter Monitoring
The processes by which organisms utilize organic substances as their nutrient sources. Contrasts with AUTOTROPHIC PROCESSES which make use of simple inorganic substances as the nutrient supply source. Heterotrophs can be either chemoheterotrophs (or chemoorganotrophs) which also require organic substances such as glucose for their primary metabolic energy requirements, or photoheterotrophs (or photoorganotrophs) which derive their primary energy requirements from light. Depending on environmental conditions some organisms can switch between different nutritional modes (AUTOTROPHY; heterotrophy; chemotrophy; or PHOTOTROPHY) to utilize different sources to meet their nutrients and energy requirements.
A group of islands of SAMOA, in the southwest central Pacific. Its capital is Pago Pago. The islands were ruled by native chiefs until about 1869. An object of American interest beginning in 1839, Pago Pago and trading and extraterritorial rights were granted to the United States in 1878. The United States, Germany, and England administered the islands jointly 1889-99, but in 1899 they were granted to the United States by treaty. The Department of the Interior has administered American Samoa since 1951. (From Webster's New Geographical Dictionary, 1988, p44)
A group of islands in Melanesia constituting a French overseas territory. The group includes New Caledonia (the main island), Ile des Pins, Loyalty Island, and several other islet groups. The capital is Noumea. It was discovered by Captain Cook in 1774 and visited by various navigators, explorers, and traders from 1792 to 1840. Occupied by the French in 1853, it was set up as a penal colony 1864-94. In 1946 it was made a French overseas territory. It was named by Captain Cook with the 5th and 6th century A.D. Latin name for Scotland, Caledonia. (From Webster's New Geographical Dictionary, 1988, p830 & Room, Brewer's Dictionary of Names, 1992, p375)
Papua New Guinea
A country consisting of the eastern half of the island of New Guinea and adjacent islands, including New Britain, New Ireland, the Admiralty Islands, and New Hanover in the Bismarck Archipelago; Bougainville and Buka in the northern Solomon Islands; the D'Entrecasteaux and Trobriand Islands; Woodlark (Murua) Island; and the Louisiade Archipelago. It became independent on September 16, 1975. Formerly, the southern part was the Australian Territory of Papua, and the northern part was the UN Trust Territory of New Guinea, administered by Australia. They were administratively merged in 1949 and named Papua and New Guinea, and renamed Papua New Guinea in 1971.
Indian Ocean Islands
Numerous islands in the Indian Ocean situated east of Madagascar, north to the Arabian Sea and east to Sri Lanka. Included are COMOROS (republic), MADAGASCAR (republic), Maldives (republic), MAURITIUS (parliamentary democracy), Pemba (administered by Tanzania), REUNION (a department of France), and SEYCHELLES (republic).

Monitoring of ichthyic fauna in artificial reefs along the Adriatic coast of the Abruzzi Region of Italy. (8/350)With the support of European Community funds, three submerged artificial reefs composed of concrete cubes, bell-shaped modules and natural rocks were deployed along the Adriatic coast of the Abruzzi Region to increase the fish population and to prevent illegal trawling. The Provincial governments of Teramo and Pescara requested the Istituto Zooprofilattico Sperimentale dell'Abruzzo e del Molise 'G. Caporale' to monitor nectobenthic populations. Three sampling operations were conducted each year for each artificial reef. The authors present the results of a study conducted between 2005 and 2007, comparing the catches from the artificial reefs with those from the control sites using several diversity indexes. Artificial reef areas revealed greater species diversity and richness than the control sites. This study demonstrates the value of artificial reefs in response to the problem of low income, non-commercial fisheries as well as to the issue of over-exploitation of halieutic resources. In addition, the authors suggest that artificial reefs may be capable of activating habitat diversification processes that will increase biodiversity. (+info)
Coral reef ecosystems | National Oceanic and Atmospheric Administration
Unfortunately, coral reef ecosystems are severely threatened. Some threats are natural, such as diseases, predators, and storms. Other threats are caused by people, including pollution, sedimentation, unsustainable fishing practices, and climate change, which is raising ocean temperatures and causing ocean acidification. Many of these threats can stress corals, leading to coral bleaching and possible death, while others cause physical damage to these delicate ecosystems. During the 2014-2017 coral bleaching event, unusually warm waters (partially associated with a strong El Niño) affected 70% of coral reef ecosystems worldwide. Some areas were hit particularly hard, like the Great Barrier Reef in Australia, where hundreds of miles of coral were bleached. Corals are able to recover from bleaching events if conditions improve before they die, though it can take many years for the ecosystems to fully heal. Scientists are also testing new ways to help coral reef ecosystems, such as growing coral in ...
The impact of habitat condition on parasitism of herbivorous coral reef fishes - ARC Centre of Excellence for Coral Reef Studies
Coral reefs are among the worlds most biodiverse, yet most threatened ecosystems. Climate change is greatly compounding local anthropogenic stressors, with many reefs transitioning from coral-dominant to less functional states. These changes in benthic habitat alter the abundance and composition of reef-associated organisms and their subsequent interactions. Of particular importance to ecosystem function are the interactions between parasites, their hosts and their environment. Due to reductions in habitat condition, altered host-parasite interactions have affected ecosystem function and disease prevalence in terrestrial and coastal systems. Reductions in habitat condition can therefore create negative feedbacks that may further affect ecosystem function. To date, the effects of habitat condition on host-parasite interactions have not been investigated on coral reefs. The objective of my PhD is to investigate how the condition of coral reef habitats affects parasitism of coral reef fishes. This ...
Coral Reefs likely to disappear by the end of the century | EarthScape
Coral reefs will be gone by the end of the century, according to a top UN Scientist. This would give coral reefs the dubious accolade of being the first entire ecosystem to have been destroyed by human activity. In the recently published book Our Dying Planet, Professor Peter Sale writes that coral reef ecosystems are very likely to disappear by the end of this century, in what would be a new first for mankind - the extinction of an entire ecosystem. Sale, who leads a team at the United Nations University Institute for Water, Environment and Health, reports that the decline in coral reefs is mainly due to climate change and ocean acidification. Other activities, including overfishing, pollution and coastal development, have also had a devastating impact on the worlds coral reefs. Were creating a situation where the organisms that make coral reefs are becoming so compromised by what were doing that many of them are going to be extinct, and the others are going to be very, very rare, says Sale.
Relationships between Host Phylogeny, Host Type and Bacterial Community Diversity in Cold-Water Coral Reef Sponges
Cold-water coral reefs are known to locally enhance the diversity of deep-sea fauna as well as of microbes. Sponges areamong the most diverse faunal groups in these ecosystems, and many of them host large abundances of microbes in theirtissues. In this study, twelve sponge species from three cold-water coral reefs off Norway were investigated for therelationship between sponge phylogenetic classification (species and family level), as well as sponge type (high versus lowmicrobial abundance), and the diversity of sponge-associated bacterial communities, taking also geographic location andwater depth into account. Community analysis by Automated Ribosomal Intergenic Spacer Analysis (ARISA) showed that asmany as 345 (79%) of the 437 different bacterial operational taxonomic units (OTUs) detected in the dataset were sharedbetween sponges and sediments, while only 70 (16%) appeared purely sponge-associated. Furthermore, changes inbacterial community structure were significantly related to sponge ...
1200 year paleoecological record of coral community development from the terrigenous inner shelf of the Great Barrier Reef |...
Increased terrestrial sediment and nutrient yields are regarded as significant threats to coral reef health. Within the central Great Barrier Reef lagoon, where water quality has reportedly declined since European settlement (since ca. A.D. 1850), inner-shelf reef conditions have purportedly deteriorated. However, the link between reef decline and water-quality change remains controversial, primarily because of a lack of pre-European period ecological baseline data against which to assess contemporary ecological states. Here we present a high-resolution record of reef accretion and coral community composition from a turbid-zone, nearshore reef on the inner shelf of the Great Barrier Reef; the record is based on six radiocarbon date-constrained cores, and extends back to ca. 1200 calibrated yr B.P. Results demonstrate not only the potential for coral communities to initiate and persist in settings dominated by fine-grained terrigenous sediment accumulation, but also that a temporally persistent ...
WildAlchemist: Coral Reefs Being Destroyed by Ocean Acidification from Greenhouse Gases
The acidification of the ocean due to the industrial emission of carbon dioxide is destroying the worlds coral reefs, a coalition of marine experts has warned in the recently released Honolulu Declaration. Coral reefs are at the heart of our tropics, and millions of people around the world depend on these systems for their livelihoods, said Lynne Hale, director of The Nature Conservancys Marine Initiative. Without urgent action to limit carbon dioxide emissions and improve management of marine protected areas, even vast treasured reefs like the Great Barrier Reef and Northwestern Hawaiian Islands will become wastelands of dead coral. Coral reefs have long been known to be threatened by effects of global warming, including coral bleaching, higher ocean temperatures and rising sea levels. But these threats are surpassed by the dangers of ocean acidification, which was named the number one threat to ocean life by scientists from the International Coral Reef Symposium in July. For many years, ...
Echinoid herbivores and coral reef resilience | Moorea Coral Reef LTER
Anthropogenic impacts and climate change are increasing the frequency and intensity at which ecosystems are being perturbed. On tropical reefs, disturbances can result in loss of live coral and sometimes initiate a transition to an alternative community state, frequently one dominated by macroalgae. Because algae-dominated reefs may have lower productivity, decreased species diversity and reduced ecosystem services, there has been considerable interest in elucidating the mechanisms that mediate a transition to an algae dominated state or the re-establishment of coral. In this dissertation I explore how physical attributes of a coral reef and the echinoid and fish communities control algal growth and influence the return to coral dominance. Recent disturbances in Moorea, French Polynesia offer an opportunity to examine the effects of architectural complexity of the substrate on recruitment of new coral colonists. I explore how the success of new coral colonists is affected by variation in ...
Deep reefs unlikely to save shallow coral reefs - Scienmag: Latest Science and Health News
Dr Pim Bongaerts, a Research Fellow at The University of Queenslands Global Change Institute (GCI) and ARC Centre of Excellence for Coral Reef Studies, and lead author of the study, said deep reefs share coral species with the shallow reef, which has led to the idea that deep reefs could be an important source of larvae and help to reseed shallow reefs. We argue that this concept of deep coral populations reseeding their shallow-water counterparts may be relevant to some species, but is ultimately unlikely to aid more broadly in the recovery of shallow reefs, he said. Given the impossibility of tracking the movements of individual coral larvae on the reef, understanding the connectivity between shallow and deep coral populations relies on methods that assess the genetic similarity between coral populations. The team focused on the relatively isolated reef system of Bermuda in the Western Atlantic where they screened the genomes of more than 200 individual coral colonies from shallow and ...

Chantecaille Coral Reefs Palette for Spring 2012
With the Coral Reefs Palette, Chantecaille has continued its tradition of offering must-have makeup with an environmental benefit. Chantecaille has proudly joined the Marine Conservation Institute in their efforts to protect 10% of the worlds oceans by 2020. The oceans cover 71% of the earth, providing 80% of our oxygen and food for 3.5 billion people; yet less than one half of one percent of our oceans are protected. The health of the ocean is vital, and coral reefs are the alert system. Today three quarters of the worlds coral reefs are at risk due to over-fishing, pollution, and global warming. Maintaining 10% of the oceans ecosystems as no-take marine protected areas is the best chance for corals survival. Five percent of the proceeds from the Coral Reefs Palette will be donated to the Marine Conservation Institute to help meet our goals (not their goals, our goals ...
Acanthurus guttatus (Mustard Surgeonfish, Mustard Tang, Spotband Surgeonfish, Spotted Surgeonfish, Spotted Tang, Whitespotted...
Surgeonfishes show varying degrees of habitat preference and utilization of coral reef habitats, with some species spending the majority of their life stages on coral reef while others primarily utilize seagrass beds, mangroves, algal beds, and /or rocky reefs. The majority of surgeonfishes are exclusively found on coral reef habitat, and of these, approximately 80% are experiencing a greater than 30% loss of coral reef area and degradation of coral reef habitat quality across their distributions. However, more research is needed to understand the long-term effects of coral reef habitat loss and degradation on these species populations. Widespread coral reef loss and declining habitat conditions are particularly worrying for species that recruit into areas with live coral cover, especially as studies have shown that protection of pristine habitats facilitate the persistence of adult populations in species that have spatially separated adult and juvenile habitats (Comeros-Raynal et al. 2012 ...

Coral Reef Ecology Field Course (Masters) module : University of Sussex
15 credits, Level 7 (Masters). Autumn teaching. Coral reefs are one of the most ecologically and economically important habitats on the planet. They have exceptional levels of biodiversity, are critical to the life-history and development of many pelagic as well as reef-associated marine species, and provide critical ecosystem services upon which many human communities rely.. However, coral reefs are also globally threatened from direct human activities and the indirect impact of climate change. Coral reefs therefore provide both an exceptional setting to learn about marine ecology, and also one for which there is a real and urgent need for an improved understanding to inform policy and conservation management strategies.. This field course will be involve scuba and snorkel-based data collection at coral reefs, giving you the opportunity to learn and apply techniques from marine biology, develop and test scientific hypotheses, and gain an in-depth understanding of the unique ecosystem of coral ...
Lionfish Decimating Other Tropical Fish Populations, Threaten Coral Reefs | News and Research Communications | Oregon State...
CORVALLIS, Ore. - The invasion of predatory lionfish in the Caribbean region poses yet another major threat there to coral reef ecosystems - a new study has found that within a short period after the entry of lionfish into an area, the survival of other reef fishes is slashed by about 80 percent.. Aside from the rapid and immediate mortality of marine life, the loss of herbivorous fish also sets the stage for seaweeds to potentially overwhelm the coral reefs and disrupt the delicate ecological balance in which they exist, according to scientists from Oregon State University.. Following on the heels of overfishing, sediment depositions, nitrate pollution in some areas, coral bleaching caused by global warming, and increasing ocean acidity caused by carbon emissions, the lionfish invasion is a serious concern, said Mark Hixon, an OSU professor of zoology and expert on coral reef ecology.. The study is the first to quantify the severity of the crisis posed by this invasive species, which is native ...

Quantifying Coral Reef Ecosystem Services | Science Inventory | US EPA
Coral reefs have been declining during the last four decades as a result of both local and global anthropogenic stresses. Numerous research efforts to elucidate the nature, causes, magnitude, and potential remedies for the decline have led to the widely held belief that the recovery of coral reefs is unlikely if public and private sector decisions that affect coral reefs continue to ignore the economic value of the goods and services (ecosystem services) they provide. However, including ecosystem services in a decision process requires that they be characterized and quantified (and subsequently valued). In particular, the scientific contribution to the decision process should include identifying which coral reef attributes are associated with which ecosystem services, how those attributes are affected by human activities, and how human activities may affect the future provision of ecosystem services. This knowledge would place the decision process on a sounder scientific footing and provide a ...
Social-environmental drivers inform strategic management of coral reefs in the Anthropocene. | NCBS
Without drastic efforts to reduce carbon emissions and mitigate globalized stressors, tropical coral reefs are in jeopardy. Strategic conservation and management requires identification of the environmental and socioeconomic factors driving the persistence of scleractinian coral assemblages-the foundation species of coral reef ecosystems. Here, we compiled coral abundance data from 2,584 Indo-Pacific reefs to evaluate the influence of 21 climate, social and environmental drivers on the ecology of reef coral assemblages. Higher abundances of framework-building corals were typically associated with: weaker thermal disturbances and longer intervals for potential recovery; slower human population growth; reduced access by human settlements and markets; and less nearby agriculture. We therefore propose a framework of three management strategies (protect, recover or transform) by considering: (1) if reefs were above or below a proposed threshold of ,10% cover of the coral taxa important for structural ...

IW:LEARN | Projects - Coral Reef Targeted Research and Capacity Building for Management
Over the past ten years, an increasing awareness of the importance of coral reefs has been evident, especially in light of their rapid decline in many regions and their significance to developing countries. However, what remains fundamentally unknown about these ecosystems is alarming, especially when management interventions are becoming increasingly important. The Coral Reef Targeted Research for Capacity Building and Management Program (CRTR) was created to fill critical information gaps for coral reef ecosystems in 4 major regions (Eastern Africa, Mesoamerica, the Philippines, and Australasia) and to link the findings to strengthen management actions and policy. The program is envisioned over a three-phase, 15 year period and involves a network of over 70 international scientists representing more than 40 institutions worldwide. The project has established a global network of eminent coral reef scientists working together across disciplines and regions so that: Key knowledge gaps can be ...
Rapid reef island formation and stability over an emerging reef flat: Bewick Cay, northern Great Barrier Reef, Australia |...
A model that resolves reef island formation in relation to both reef platform substrate development and mid-Holocene sea-level change is presented for Bewick Island, northern Great Barrier Reef, based on morphostratigraphic analysis and radiometrically dated island sediments and reef corals. On Bewick Island, microatolls record reef-flat development at higher sea level (+1.5 m) by 6500 yr B.P. Island building began on a partially emergent reef flat 5000-4000 yr B.P., when sea level was 0.5 m above present. As sea level fell to its present level, the reef platform process window closed and the island core stabilized. Results present the first unequivocal evidence of island building directly over a reef flat comprising microatolls, and the first detailed model of island formation from the Great Barrier Reef. The model demonstrates that the interplay of sea level and reef surface elevation can vary between sites but their convergence is critical for island initiation. Future trajectories of island ...

Common Herbicide a Threat To Great Barrier Reef, Report Says - Yale E360
A popular herbicide used widely in coastal regions of Australia has been found at dangerous levels in the Great Barrier Reef, posing a toxic threat to the worlds largest coral reef system. The chemical Diuron, which is used largely by sugar cane farmers along the Queensland coast, was found at levels 55 times higher than safety standards in creeks that drain into the reef, and at levels 100 times the safe standards in the reef itself, according to a new report by the World Wildlife Fund. After a decade-long review, the Australian government on Tuesday announced it would continue a suspension of the chemical except in the countrys tropical regions. A decision on a permanent ban will be made by November, the Australian Pesticides and Veterinary Medicines Authority said. In a recent report, the Great Barrier Reef Marine Park Authority called a decline in the quality of water in catchment areas one of the greatest threats facing the reef. Nick Heath, the WWF freshwater and reef coordinator, said ...
Tory Chase - ARC Centre of Excellence for Coral Reef Studies
Interspecies interactions, especially symbiotic relationships, are at the heart of ecosystem functioning, stability, and diversity on coral reefs. The effects of coral-associated fish on their host coral colony are dynamic in terms of the fish-derived benefits that promote coral growth. The ecosystem function of this aggregating fish and coral mutualism may be widespread and have a significant impact on coral demographic rates and health. Considering that coral populations occur across a broad range of environmental conditions (e.g. latitude, light, reef position), and interact with a variety of fish species, knowledge of how these factors operate in synergy is essential in understanding how corals are impacted by aggregating fish interactions.. This project will investigate the effects of coral-fish symbioses on coral populations. Specifically, my proposed research will determine where the symbiosis is established and the variations, how it interacts with environmental factors (nutrients, ...
Climate Change, Human Impacts, and the Resilience of Coral Reefs | Science
The diversity, frequency, and scale of human impacts on coral reefs are increasing to the extent that reefs are threatened globally. Projected increases in carbon dioxide and temperature over the next 50 years exceed the conditions under which coral reefs have flourished over the past half-million years. However, reefs will change rather than disappear entirely, with some species already showing far greater tolerance to climate change and coral bleaching than others. International integration of management strategies that support reef resilience need to be vigorously implemented, and complemented by strong policy decisions to reduce the rate of global warming.. ...

Revision}} This article describes the habitat of the coral reefs. It is one of the sub-categories within the section dealing with biodiversity of [[marine habitats and ecosystems]]. It gives an overview of the formation, distribution, biology, [[zonation]], requirements for development, biota and threats. ==Introduction== Coral reefs are one of the most diverse [[ecosystems]] in the world. The organisms belong to the Phylum [http://www.marinespecies.org/aphia.php?p=taxdetails&id=1267 Cnidaria]. The best known type of corals is the one living in clear, warm tropical waters with plenty of colourful fishes. This is a rocky, shallow water type. The water is clear because of the low concentrations of [[nutrient,nutrients]]. But there are also deep water corals that live in dark cold waters and soft corals that live in shallow, cold waters. They are wave resistant rock structures, created by calcium carbonate -secreting animals and plants. [[image:Coral reef.jpg,right,thumb,300px,caption,Coral ...
Flattening of Caribbean coral reefs: region-wide declines in architectural complexity | Proceedings of the Royal Society of...
The architectural complexity of coral reefs has declined drastically over the last 40 years throughout the Caribbean. Structurally complex reefs with a rugosity of greater than 2 have been virtually lost from the entire region. Today, the flattest reefs (rugosity less than 1.5) comprise approximately 75 per cent of the total compared with approximately 20 per cent in the 1970s, with most of the increase in the proportion of flattest reefs occurring in the 2000s. The high proportion of complex reefs in the 1960s and 1970s is unlikely to result from researchers tending to visit just the most pristine reefs at this time, because less architecturally-complex categories were also well represented during this period. The loss of architectural complexity is nonlinear and has occurred over three distinct phases that coincide closely with large-scale events that have affected Caribbean reef ecosystems. The rate of decline was steepest prior to 1985. The sample sizes are small and variance high during the ...
Threats to Reefs - Coral Reef Systems Multimedia
As the name would suggest, marine snow resembles snowflakes suspended in the oceans water column. Marine snow is the aggregations of a variety of suspended material consisting of calcareous algae, organic detritus, and mucus secreted by plankton, algae, bacteria and corals. Increased nutrient concentrations in coastal waters enhance algal growth, which indirectly increases the levels of marine snow (review by Wolanski et al. 2003). Increased carbon levels resulting from sewage runoff and mucus secretion* also directly influence marine snow. Until recently, the significance of marine snow and coral reef health has been neglected. The adhesive property of marine snow means that it readily attaches itself to suspended sediment (fine clay) from coastal runoff resulting in it becoming negatively buoyant. This muddy marine snow is detrimental and even lethal to coral reefs as it settles on the reef smothering it (Fabricius and Wolanski 2000). Rich in carbohydrates, marine snow is a source of energy ...
Long-term monitoring of coral reef fish assemblages in the Western central pacific | Scientific Data
Throughout the tropics, coral reef ecosystems, which are critically important to people, have been greatly altered by humans. Differentiating human impacts from natural drivers of ecosystem state is essential to effective management. Here we present a dataset from a large-scale monitoring program that surveys coral reef fish assemblages and habitats encompassing the bulk of the US-affiliated tropical Pacific, and spanning wide gradients in both natural drivers and human impact. Currently, this includes |5,500 surveys from 39 islands and atolls in Hawaii (including the main and Northwestern Hawaiian Islands) and affiliated geo-political regions of American Samoa, the Commonwealth of the Northern Mariana Islands, Guam, and the Pacific Remote Islands Areas. The dataset spans 2010-2017, during which time, each region was visited at least every three years, and ~500-1,000 surveys performed annually. This standardised dataset is a powerful resource that can be used to understand how human, environmental and
Color Changes In Coral Reefs Due To Increased Growth - Redorbit
New research has provided insight into the basic immune response and repair mechanisms of corals to disease and changing environmental conditions.. The study, published in the latest issue of the journal Coral Reefs, found that increased growth is the underlying physiological process associated with disease, wounding and stress-related color changes in reef-building corals.. The study investigated distinct green fluorescent protein (GFP)-like pigments responsible for the green, red and purple-blue colors of many reef-building corals.. By examining these GFP- pigments in four coral species from the Arabian/Persian Gulf, Red Sea and Fiji, researchers found that their presence shows growing tissue in growing branch tips and margins of healthy coral colonies; as well as in disrupted colony parts, in comparison to un-disrupted areas.. Dr Joerg Wiedenmann, Senior Lecturer of Biological Oceanography and Head of the Coral Reef Laboratory at the University of Southampton, who led the study, says: The ...
Carbon chemistry on inshore reefs of the Great Barrier Reef 2011 - 2012 (NERP TE 5.2, AIMS)
This dataset contains data on carbon chemistry on inshore reefs of the Great Barrier Reef (GBR). Main parameters measured were temperature, total alkalinity and dissolved inorganic carbon. The data was collected six times over two years (September 2011 - June 2012) covering a comprehensive latitudinal range. The aim of this study was to investigate carbon chemistry on inshore reefs, and compare it to offshore reefs and historical data. Research to date on reef calcification and inorganic carbon dynamics within the GBR system has largely focused upon on-reef processes on mid- and outer-shelf reefs. Relatively little work has been done on the shelf-scale dynamics of inorganic carbon in the GBR system and almost no consideration has been given to the many inshore reefs close to the coast that are under the greatest threat from increases in runoff of sediment, nutrients and pesticides. The ratio of primary productivity and respiration (P/R) of inshore reefs are often lower than on reefs further from ...

Frontiers | Caribbean Near-Shore Coral Reef Benthic Community Response to Changes on Sedimentation Dynamics and Environmental...
Coral reefs are facing unprecedented global, regional and local threats that continue to degrade near-shore habitats. Water quality degradation, due to unsustainable development practices at coastal watersheds, is one of the greatest stressors across multiple spatial scales. The goal of this study was to assess near-shore coral reef benthic community spatio-temporal response to sedimentation patterns, weather, and oceanographic dynamics at Bahía Tamarindo and Punta Soldado in Culebra Island, Puerto Rico. Benthic data were collected across a distance gradient from the shore through high-resolution images at marked belt transects. Environmental data were assessed and contrasted with benthic assemblages using multivariate correlations and multiple linear regression. Coral colony abundance and coral recruit assemblages showed significant variation among seasons, sites and distance zones (PERMANOVA, p Porites astreoides, P. porites, and Siderastrea radians.

NOAA Ocean Explorer: Coral Ecosystem Connectivity 2015: Background: Coral Reef Connectivity
University of Miamis Rosenstiel School of Marine and Atmospheric Science The persistence of coral reef ecosystems may largely depend on the exchange of offspring between populations that exist on the edge of species ranges. While reef-building corals expand to the subtropics, their range is not only bounded by latitude, but also by water depth. This is mostly because sunlight attenuates very quickly through the water column and corals harbor microscopic photosynthetic symbiotic algae, which need to uptake light to help nourish the coral. Light-dependent coral reefs and associated benthic communities found between 30 and 100 meters (100-330 feet) in the Gulf of Mexico are called mesophotic coral ecosystems (MCEs) and are central to our study. The MCEs of Pulley Ridge, located 66 kilometers west of the Dry Tortugas, inhabit a relatively stable environment, decoupled from stresses related to the proximity of coastal pollution or from water temperature fluctuations and mass bleaching affecting ...

New Reefs Discovered In Brazil - Redorbit
Doubling the size of the southern Atlantics largest reef system. Scientists announced yesterday the discovery of reef structures they believe doubles the size of the Southern Atlantic Oceans largest and richest reef system, the Abrolhos Bank, off the southern coast of Brazils Bahia state. The newly discovered area is also far more abundant in marine life than the previously known Abrolhos reef system, one of the worlds most unique and important reefs.. Researchers from Conservation International (CI), Federal University of EspÃ -rito Santo and Federal University of Bahia announced their discovery in a paper presented today at the International Coral Reef Symposium in Fort Lauderdale. We had some clues from local fishermen that other reefs existed, but not at the scale of what we discovered, says Rodrigo de Moura, Conservation International Brazil marine specialist and co-author of the paper. It is very exciting and highly unusual to discover a reef structure this large and harboring such ...
Scientists get early look at hurricane damage to Caribbean coral reefs - University at Buffalo
BUFFALO, N.Y. - When hurricanes Maria and Irma tore through the Caribbean, they not only wreaked havoc on land, but also devastated ocean ecosystems.. Coral reefs off St. John, part of the U.S. Virgin Islands, suffered severe injury during the storms, say scientists from the University at Buffalo and California State University, Northridge who traveled there in late November to assess the damage - the first step in understanding the reefs recovery.. Some coral colonies lost branches. Others were cloaked in harmful algal growth. Many - weakened by the hurricanes - were left with ghostly, feather-like strands of bacteria hanging off open wounds where bits of coral had been scraped off.. Researchers also observed sites where whole coral colonies, akin to individual trees in a forest, had been swept away by the fury of the storms..

Coral reef fish smell leaves to find island homes | Proceedings of the Royal Society of London B: Biological Sciences
The clownfish A. percula clearly has a close association with coral reefs surrounding vegetated islands. Both clownfish and host anemone numbers are high on island reefs and sparse on other emergent reefs. Within island reef systems, numbers are the greatest immediately adjacent to the islands themselves, where they are often found beneath overhanging vegetation. Given the strong association between host anemones and island reefs, A. percula larvae can clearly maximize their chances of finding a suitable settlement site by being able to locate and orient towards islands. The islands themselves are a potential source of many olfactory water-borne cues that would not be emanating from reefs without islands. Elevated levels of organic material from the lush tropical rainforest vegetation could clearly extend some distance from the islands. The experimental data presented here strongly suggest that A. percula has an innate olfactory attraction to rainforest vegetation, and once detected, could use ...
Seachem Reef Carbonate - TPM
Reef Carbonate™ is a concentrated (4,000 meq/L) optimized blend of carbonate and bicarbonate salts designed to restore and maintain alkalinity in the reef aquarium. Calcium and carbonates are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health. To prevent this you must provide carbonates (Reef Carbonate™) and calcium (Reef Advantage Calcium™ or Reef Complete®). Whereas competing products simply use sodium bicarbonate, Reef Carbonate™ is made with a blend of carbonate and bicarbonate salts. This blend of salts results in Reef Carbonate™ yielding a pK of roughly 9.0 in saltwater (higher than competing products). In a closed reef system, the multitude of organics produced by reef inhabitants tends to force pH downward, but the advantage of Reef Carbonates™ higher pK is a stabilization of pH around 8.3-8.4. Competing products formulations make them incapable of such a claim, so pH will always fall below desirable
NOAA 200th: How Pollution Affects Coral Reefs
Pollution from land-based sources is a primary cause of coral reef degradation throughout the world. In the Caribbean, for example, approximately 80 percent of ocean pollution originates from activities on land. As human populations expand in coastal areas, development alters the landscape, increasing runoff from land. Runoff often carries large quantities of sediment from land-clearing, high levels of nutrients from agricultural areas and sewage outflows, and pollutants such as petroleum products and pesticides. These land-based sources of pollution threaten coral reef health.. Excess nutrients result in poor water quality, leading to decreased oxygen and increased nutrients in the water (eutrophication). This can lead to enhanced algal growth on reefs, crowding out corals and significantly degrading the ecosystem. In addition, sediment deposited onto reefs smothers corals and interferes with their ability to feed and reproduce. Finally, pesticides interfere with coral reproduction and growth. ...
Coral and Coral Reef - Biology Of Corals - Polyps, Zooxanthellae, Coenosarc, and Single - JRank Articles
Single-celled dinoflagellate algae known as zooxanthellae live symbiotically within coral polyps. Chemical exchanges occur between the coral polyps and zooxanthellae, and both thrive in a mutually beneficial relationship (mutualism). The zooxanthellae, which are essentially tiny green plants that can produce food from sunlight, water, and dissolved minerals, supply some coral species with more than 90% of their nutrition on sunny days. In exchange for nutrients, the coral polyps supply a habitat and essential minerals to the algae. Another result of this relationship is more rapid development of coral reefs. During photosynthesis, the zooxanthellae remove carbon dioxide from the water, which promotes calcium carbonate production, in turn allowing the coral to more easily secrete its home.. In addition to the food provided by their zooxanthellae, corals prey on tiny planktonic organisms. Some corals paralyze their prey using stinging cells, or nematocysts, located on their tentacles. Other corals ...
Seachem - Reef Pack: Enhancer
The Enhancer Pack combines those products essential for any reef (Reef Complete®, Reef Carbonate™, and Reef Plus™).. Reef Calcium™ is a concentrated (50,000 mg/L) bioavailable polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH. Polygluconate complexation confers several benefits: it increases the bioavailability of the calcium, it provides a rich source of metabolic energy to help maintain peak coral growth, and it prevents calcium precipitation/alkalinity depletion. Polygluconate contains no nitrogen or phosphorous, thus it is biologically impossible for it to lead to algae growth in a properly maintained reef system. Reef Calcium™ may be used alone to maintain calcium but will provide enhanced levels of coral growth when used in conjunction with an ionic calcium supplement (Reef Complete®, Reef Advantage Calcium™). Reef Calcium™ is intended to maintain calcium levels; if calcium becomes seriously depleted one should either ...
Status and review of health of Indian coral reefs
Status of reef health incorporating species-wise cover of scleractinians has been reported covering 61 stations in 29 reef locations of the four major reef regions in India as of March 2011, alongside a review of available reef health data since 1998 until 2011 Coral bleaching has been identified as a major factor determining the live coral cover (in the order high to low impact) in Lakshadweep, Gulf of Mannar (GOM) and Andaman reefs Reductions in live cover (from 2010) were observed in Lakshadweep and GOM reefs Recovery from the bleaching event in 2010 was reported from Andaman, though long-term impacts of bleaching, reef area loss due to seismic up-lift and the 2004-tsunami were observed by the declining trend in reef health Local scale stressors are more intense in Gulf of Kachchh (GOK) and GOM reefs, however are more chronic in the former, which is reflected in the species composition as stress tolerators (Edinger and Risk 2000) forming the major cover in these reefs In GOM, recovery from ...
A Super-Algae To Save Our Seas? Genetic Engineering Species To Save Corals | Ocean Leadership
Coral reefs are our most diverse marine habitat. They provide over US$30 billion to the world economy every year and directly support over 500 million people. However, they are vulnerable with climate change impact models predicting that most of our coral reefs will be eradicated within this century if we do not act immediately to protect them.. Dr Rachel Levin from The University of New South Wales, Australia and her international team of researchers may have found a solution to reduce coral bleaching by genetically engineering the microalgae found in corals, enhancing their stress tolerance to ocean warming.. These microalgae are called Symbiodinium, a genus of primary producers found in coral that are essential for coral reef health and, thereby, critical to ocean productivity. Symbiodiniumphotosynthesize to produce molecules that feed the corals, which is necessary corals to grow and form coral reefs.. Coral bleaching is caused by changes in ocean temperatures which harm Symbiodinium, ...
Oil impairs ability of coral reef fish to find homes and evade predators | GoMRI
A team of fisheries biologists led by Jacob Johansen and Andrew Esbaugh of The University of Texas Marine Science Institute have discovered that oil impacts the higher-order thinking of coral reef fish in a way that could prove dangerous for them--and for the coral reefs where they make their home.
January 2014 | JAMS
Coral reefs are fundamental in providing ecological, social and economical benefits to local communities, governments and nations. In Australia, the Great Barrier Reef is an iconic symbol in our national psyche, representing approximately 17% of the global tropical coral reef area with an estimated economic value at greater than AUD$5 billion per year. Coral reefs are constructed through the close association between reef building corals and their symbiotic dinoflagellate microalgae (Symbiodinium). However just as in other animal systems, corals are now thought of as a holobiont, forming additional close and intricate associations with a range of other microbial organisms such as bacteria, archaeae, fungi and viruses. Over the last decade a greater understanding has been obtained in how corals shape and structure their microbial partners, providing important functional roles in maintaining overall coral fitness. The cycling of nitrogen and sulfur compounds within the holobiont are increasingly ...
Coral Reef Ecosystem Studies (CREST)
By combining our research activities involving mapping, monitoring, and retrospectively investigating reef processes such as calcification, reef metabolism, and microbial cycling, we will reveal linkages among them and establish connections to ecosystem services or outputs including reef edification, seawater chemistry, sand production, and habitat construction. Our work addresses several key issues related to the current status and potential declining health and resilience of shallow-water reef communities in the U.S. Caribbean, Gulf of Mexico, and Florida Keys. Improved understanding and information resulting from our work will help guide policies and best management practices to preserve and restore U.S. coral reef resources.. The specific objectives of this project are to identify and describe the processes that are important in determining rates of coral-reef construction. How quickly the skeletons of calcifying organisms accumulate to form massive barrier-reef structure is determined by ...

Small Marine Protected Areas in Fiji Provide Refuge for Reef Fish Assemblages, Feeding Groups, and Corals
The establishment of no-take marine protected areas (MPAs) on coral reefs is a common management strategy for conserving the diversity, abundance, and biomass of reef organisms. Generally, well-managed and enforced MPAs can increase or maintain the diversity and function of the enclosed coral reef, with some of the benefits extending to adjacent non-protected reefs. A fundamental question in coral reef conservation is whether these benefits arise within small MPAs (|1 km2), because larval input of reef organisms is largely decoupled from local adult reproduction. We examined the structure of fish assemblages, composition of fish feeding groups, benthic cover, and key ecosystem processes (grazing, macroalgal browsing, and coral replenishment) in three small (0.5-0.8 km2) no-take MPAs and adjacent areas where fisheries are allowed (non-MPAs) on coral reefs in Fiji. The MPAs exhibited greater species richness, density, and biomass of fishes than non-MPAs. Furthermore, MPAs contained a greater abundance and
The Great Barrier Reef by Michael Raffel on Prezi
The Great Barrier Reef is home to about 360 species of hard corals including bottlebrush coral, bubble coral, brain coral, mushroom coral, staghorn coral, tabletop coral and needle coral. Hard corals, also known as stony corals, are a group of marine animals that live in shallow tropical waters and are responsible for building the structure of a coral reef. Colonies of hard corals grow in various shapes and sizes such as mounds, plates and branches. As previous coral colonies die, new ones grow on top of the limestone skeletons of their predecessors. Over time, this growth creates the three-dimensional architecture of a coral reef. Colonies of hard corals consist of thousands of small individal invertebrates referred to as coral polyps. Each polyp is radially symmetrical with a tube-like body that has a tentacle-rimmed mouth at the tip that it uses to feed ...
E-GEOD-42684 - High natural gene expression variation in the reef-building coral Acropora millepora: Potential for acclimative...
This experiment assessed the natural gene expression variation present between colonies of the Indo-Pacific reef-building coral Acropora millepora, and additionally explored whether gene expression differed between two different intron haplotypes according to intron 4-500 in a carbonic anhydrase homolog. This study found no correspondence between host genotype and transcriptional state, but found significant intercolony variation, detecting 488 representing unique genes or 17% of the total genes analyzed. Such transcriptomic variation could be the basis upon which natural selection can act. Underlying variation could potentially allow reef corals to respond to different environments. Whether this source of variation and the genetic responses of corals and its symbionts will allow coral reefs to cope to the rapid pace of global change remains unknown. A. millepora colonies were brought to a common garden in the reef lagoon, i.e. under the same environmental conditions. This common garden combined with
Spatial Dynamics of Coral Populations in the Florida Keys by Dione W. Swanson
Coral reef degradation has been observed worldwide over the past few decades resulting in significant decreases in coral cover and abundance. However, there has not been a clear framework established to address the crucial need for more sophisticated understanding of the fundamental ecology of corals and their response to environmental stressors. Development of a quantitative approach to coral population ecology that utilizes formal, well established principles of fishery systems science offers a new framework to address these issues. The goal of this dissertation is to establish a quantitative foundation for assessment of coral reefs by developing some essential ecological and population-dynamic components of a size-structured demographic model for coral populations of the Florida Keys coral reef ecosystem. The objective provides the potential to build a quantitative systems science framework for coral populations. A two-stage stratified random sampling design was implemented during two separate

Coral reef in danger and mass deaths over 20 types of fish off the coast of Qatar - Al-anwar Newspaper
Doha-based marine researchers said on Monday that high sea temperatures off the coast of Qatar caused precious coral reef in danger and mass deaths over 20 types of fish.. Experts from Qatar University carried out a study and the environment ministry has revealed that water temperatures during the fierce Gulf summer have passed 36°C (97 °F).. Researchers are concerned about the potential long-term impact on the coral reef in waters surrounding Qatar.. The coral reef may be affected by the temperature, we dont know yet. 36°C (97 °F), this is really too much. Its really sensitive to high temperatures, Qatar University marine biology Professor Dr Ibrahim Al-Maslamani said.. If the system shuts down it will really be a disaster, he added.. Not only the heats potential impact on the reef, fish have also been affected, according to Maslamani..

Convergence of DNA methylation profiles in a novel environment in the reef coral Porites astreoides
Phenotypic acclimatization is an organismal response to environmental change that may be rooted in epigenetic mechanisms. In reef building corals, organisms that are severely threatened by environmental change, some evidence suggests that DNA methylation is an environmentally responsive mediator of acclimatization. We investigated changes in DNA methylation of the reef coral Porites astreoides in response to simulated environmental change. Coral colonies were sampled from a variety of habitats on the Belize Barrier Reef and transplanted to a common garden for one year. We used restriction site associated DNA sequencing, including a methylation-sensitive variant, to subsample the genome and assess changes in DNA methylation levels after a year in the common garden. Methylation changes among the 629 CpG loci we recovered were subtle, yet coral methylomes were more similar to each other after a year in the common garden together, indicating convergence of methylation profiles in the common environment.

TY - JOUR. T1 - Consistency and inconsistency in multispecies population network dynamics of coral reef ecosystems. AU - Holstein, Daniel M.. AU - Paris, Claire B.. AU - Mumby, Peter J.. PY - 2014/3/3. Y1 - 2014/3/3. N2 - Different marine species and their larvae have characteristics that can expand or contract their potential dispersal, which can add complexity to the management of species assemblages. Here we used a multi-scale biophysical modeling framework, the Connectivity Modeling System, for the analysis of network connectivity for 5 Caribbean coral reef-associated species in order to gauge similarities and dissimilarities among species as well as among Caribbean regions. We estimated local dispersal and retention to assess regional exchanges, and our results revealed that the population structures of coral and fish are different and should thus have dissimilar management requirements in many regions, with some notable exceptions. Populations of Porites astreoides corals appear ...
Biodiversity enhances coral growth, tissue survivorship and suppression of macroalgae | Nature Ecology & Evolution
Coral reefs are declining dramatically and losing species richness, but the impact of declining biodiversity on coral well-being remains inadequately understood. Here, we demonstrate that lower coral species richness alone can suppress the growth and survivorship of multiple species of corals (Porites cylindrica, Pocillopora damicornis and Acropora millepora) under field conditions on a degraded, macroalgae-dominated reef. Our findings highlight the positive role of biodiversity in the function of coral reefs, and suggest that the loss of coral species richness may trigger negative feedback that causes further ecosystem decline.
Environmental controls of coral growth: Data driven multi-scale analyses of rates and patterns of growth in massive Porites ...
Scleractinian corals produce large amounts of calcium carbonate as they grow, sustaining the three-dimensional reef framework that supports the high productivity and biodiversity associated with tropical coral reefs. The rate of skeletal growth of corals is therefore not only essential for their fitness and ecological success, i.e. determining the ability of corals to compete for space and light, and repair structural damage caused by humans, storms, grazers and bioeroders, but can also have profound repercussions on the recovery and resilience of coral reef systems. This thesis investigates possible environmental controls of coral growth through the analyses of emergent patterns on larger spatio-temporal scales. Past growth rates and patterns in massive Porites corals sampled from around the Thai-Malay Peninsula at reef-island scales were reconstructed using sclerochronology, and examined in the context of varying climate/environment. Located within the political boundaries of Singapore, ...

Effects of age and size on the growth and physiology of scleractinian corals | Moorea Coral Reef LTER
The growth of modular organisms is achieved by the asexual iteration of conserved units, and the biological implications of this type of growth are vast. One direct consequence of modularity is the potential for exponential growth through asexual reproduction and dispersal, thereby removing the genotype from the physiological constraints of senescence and permitting it to become virtually immortal. However, senescence at the level of individual modules may still exist. Scleractinian corals are an excellent model system to test for effects of age and size because colonies often experience fission, fusion, and fragmentation, thereby decoupling the relationship between age and size. Understanding how fission and fragmentation affect coral growth is timely because the likelihood of partial mortality and fission will increase due to global degradation of coral reefs, resulting in large numbers of small, yet old, colonies. In order to test the effects of age and size on growth in corals, two ...
High natural gene expression variation in the reef-building coral Acro by Camila Granados-Cifuentes, Anthony J. Bellantuono...
Background: Ecosystems worldwide are suffering the consequences of anthropogenic impact. The diverse ecosystem of coral reefs, for example, are globally threatened by increases in sea surface temperatures due to global warming. Studies to date have focused on determining genetic diversity, the sequence variability of genes in a species, as a proxy to estimate and predict the potential adaptive response of coral populations to environmental changes linked to climate changes. However, the examination of natural gene expression variation has received less attention. This variation has been implicated as an important factor in evolutionary processes, upon which natural selection can act. Results: We acclimatized coral nubbins from six colonies of the reef-building coral Acropora millepora to a common garden in Heron Island (Great Barrier Reef, GBR) for a period of four weeks to remove any site-specific environmental effects on the physiology of the coral nubbins. By using a cDNA microarray platform, we

TY - JOUR. T1 - A snapshot of a coral holobiont. T2 - A transcriptome assembly of the scleractinian coral, Porites, captures a wide variety of genes from both the host and symbiotic zooxanthellae. AU - Shinzato, Chuya. AU - Inoue, Mayuri. AU - Kusakabe, Makoto. PY - 2014/1/15. Y1 - 2014/1/15. N2 - Massive scleractinian corals of the genus Porites are important reef builders in the Indo-Pacific, and they are more resistant to thermal stress than other stony corals, such as the genus Acropora. Because coral health and survival largely depend on the interaction between a coral host and its symbionts, it is important to understand the molecular interactions of an entire coral holobiont. We simultaneously sequenced transcriptomes of Porites australiensis and its symbionts using the Illumina Hiseq2000 platform. We obtained 14.3 Gbp of sequencing data and assembled it into 74,997 contigs (average: 1,263 bp, N50 size: 2,037 bp). We successfully distinguished contigs originating from the host ...
Conservation: Reef sharks are in major decline worldwide
The crash in shark numbers, caused largely by over-fishing, could have dire consequences for corals struggling to survive in a changing climate, researchers have said.. Sharks are top predators, playing a key role in marine ecosystems.. They did best in places where shark fishing was controlled, or where marine sanctuaries had been created.. Dr Mike Heithaus of Florida International University, US, said: At a time when corals are struggling to survive in a changing climate, losing reef sharks could have dire long-term consequences for entire reef systems.. The research, published in the journal Nature, and part of the Global FinPrint study, reveals widespread loss of reef sharks across much of the worlds tropical oceans.. Species such as grey reef sharks, blacktip reef sharks, and Caribbean reef sharks were often missing from reefs where they would historically have been found.. ...
Microarray analysis reveals transcriptional plasticity in the reef building coral Acropora millepora - [email protected]
We investigated variation in transcript abundance in the scleractinian coral, Acropora millepora, within and between populations characteristically exposed to different turbidity regimes and hence different levels of light and suspended particulate matter. We examined phenotypic plasticity by comparing levels of gene expression between source populations and following 10 days of acclimatization to a laboratory environment. Analyses of variance revealed that 0.05% of genes were differentially expressed between source populations, 1.32% following translocation into a common laboratory and 0.07% in the interaction (source population-dependent responses to translocation). Functional analyses identified an over-representation of differentially expressed genes associated with metabolism and fluorescence categories (primarily downregulated), and environmental information processing (primarily upregulated) following translocation to a lower light and turbidity environment. Such metabolic downregulation ...
Microbiological assessment of a disease outbreak on corals from Magnetic Island (Great Barrier Reef, Australia) -...
Unusual disease lesions were observed in Montipora corals on the fringing reef of Magnetic Island (Great Barrier Reef, Australia) following a period of high water temperature in early January 2002. Tissue death in Montipora spp. appeared as a black layer that spread rapidly across the colony surface, though this appeared as the final phase of disease progression (with three previous disease phases now identified, S. Anthony, unpublished). Culture and molecular-based microbial analysis of this layer did not identify a likely microbial pathogen. Despite this, DNA sequencing of microbial 16S rDNA indicated a shift in the bacterial population associated with affected coral tissue. A clone library of the healthy coral sample predominantly contained sequences within the gamma-Proteobacteria. A disease coral sample representing the margin of the black lesion and healthy coral tissue was dominated by sequences, which demonstrated low sequence identity to a range of alpha-Proteobacteria, ...
Reef Monitoring Survey October 2010 - AIMS
Summary. Fifteen reefs in the Cooktown - Lizard Island sector were surveyed for crown-of-thorns starfish and coral disease outbreaks using manta tow. Intensive SCUBA surveys for benthic organisms, reef fishes and agents of coral mortality (SCUBA searches) were also completed on sites on eight of these reefs. Preliminary results of the manta tow surveys and SCUBA searches are presented in this report. No active outbreaks of crown-of-thorns starfish (COTS) were found but one Incipient Outbreak was recorded at Startle Reef. COTS were recorded in low numbers on seven reefs during manta tow surveys with localized Incipient Outbreak levels of COTS observed on five. COTS were also observed on five reefs during SCUBA searches. COTS feeding scars were recorded on many of the survey reefs and a number of spot checks revealed a few individuals hiding in amongst the reef matrix. Above normal levels of coral mortality were also observed on parts of the Startle Reef (Incipient Outbreak). The directors of the ...

Marine Animals Supply Nutrition To Coral Reefs - Agro Ecology Innovations
It is long been identified that sharks assist nourish coral reefs, however precisely to what extent has by no means been scientifically mapped out - till now.. Pioneering research - led by scientists from Imperial School London in collaboration with marine biologists from UC Santa Barbara - discovered that the predators, by way of their fecal materials, switch essential vitamins from their open ocean feeding grounds into shallower reef environments, contributing to the general well being of those fragile ecosystems. The researchers particularly examined the function of gray reef sharks (Carcharhinus amblyrhynchos), a predatory species generally related to coral environments; however whose broader ecological role has long been debated. The worldwide workforces findings seem within the journal Proceedings of the Royal Society B.. Our examine reveals that giant cellular predators comparable to sharks could also be an important supply of vitamins for even the smallest reef creatures, comparable to ...
Materials | Free Full-Text | Decoration of ZnO Nanorods with Coral Reefs like NiO Nanostructures by the Hydrothermal Growth...
Composite nanostructures of coral reefs like p-type NiO/n-type ZnO were synthesized on fluorine-doped tin oxide glass substrates by hydrothermal growth. Structural characterization was performed by field emission scanning electron microscopy, high-resolution transmission electron microscopy, and X-ray diffraction techniques. This investigation shows that the adopted synthesis leads to high crystalline quality nanostructures. The morphological study shows that the coral reefs like nanostructures are densely packed on the ZnO nanorods. Cathodoluminescence (CL) spectra for the synthesized composite nanostructures are dominated mainly by a broad interstitial defect related luminescence centered at ~630 nm. Spatially resolved CL images reveal that the luminescence of the decorated ZnO nanostructures is enhanced by the presence of the NiO.
Brain coral - Wikipedia
Brain coral is a common name given to various corals in the families Mussidae and Merulinidae, so called due to their generally spheroid shape and grooved surface which resembles a brain. Each head of coral is formed by a colony of genetically identical polyps which secrete a hard skeleton of calcium carbonate; this makes them important coral reef builders like other stony corals in the order Scleractinia. Brain corals are found in shallow warm-water coral reefs in all the worlds oceans. They are part of the phylum Cnidaria, in a class called Anthozoa or flower animals. The lifespan of the largest brain corals is 900 years. Colonies can grow as large as 1.8 m (6 ft) or more in height. Brain corals extend their tentacles to catch food at night. During the day, they use their tentacles for protection by wrapping them over the grooves on their surface. The surface is hard and offers good protection against fish or hurricanes. Branching corals, such as staghorn corals, grow more rapidly, but are ...

Algal contact as a trigger for coral disease
In the Caribbean, a large number of coral colonies on which this alga was transplanted developed white plague whereas unexposed colonies did not. In addition, the plant was found to be a reservoir for the marine bacterium Aurantimonas coralicida, causative agent of the disease. The spread of macroalgae on coral reefs may account for the elevated incidence of coral diseases over past decades. Moreover, measures to reduce seaweed abundance may be essential if significant coral populations are to survive on coral reefs ...
Net loss of CaCO|sub|3|/sub| from coral reef communities due to human induced seawater acidification
Acidification of seawater owing to oceanic uptake of atmospheric CO2 originating from human activities such as burning of fossil fuels and land-use changes has raised serious concerns regarding its adverse effects on corals and calcifying communities. Here we demonstrate a net loss of calcium carbonate (CaCO3) material as a result of decreased calcification and increased carbonate dissolution from replicated subtropical coral reef communities (n=3) incubated in continuous-flow mesocosms subject to future seawater conditions. The calcifying community was dominated by the coral Montipora capitata. Daily average community calcification or Net Ecosystem Calcification (NEC=CaCO3 production - dissolution) was positive at 3.3 mmol CaCO3 m−2 h−1 under ambient seawater pCO2 conditions as opposed to negative at −0.04 mmol CaCO3 m−2h−1 under seawater conditions of double the ambient pCO2. These experimental results provide support for the conclusion that some net calcifying communities could become
Branched Montipora Coral (Velvet Branch or Velvet Finger Coral): SPS (Small Polyp Stony) Corals
The Branched Montipora Coral is a small polyp stony (SPS) coral often referred to as Velvet Branch, or Velvet Finger Coral. This branching coral comes in a variety of colors and is a fast growing species. The form that the coral takes in its growth will be highly variable depending on the lighting, water movement and placement within the aquarium. However, it will typically maintain its branched form in most aquariums. When the polyps are expanded, the coral has a very fuzzy appearance, with smooth growth tips adding to its overall appeal. The Branched Montipora Coral is peaceful and can be placed in close proximity to other similar peaceful corals in the reef aquarium. It is a relatively hardy coral and requires just a moderate amount of care when housed in a mature reef aquarium. It will require medium to high lighting combined with a medium water movement within the aquarium. For continued good health, it will also require the addition of calcium, strontium, and other trace elements to the ...

Food web interactions along seagrass-coral reef boundaries: Effects of by J. F. Valentine, K. L. Heck Jr. et al.
Although early studies qualitatively documented the importance of cross-habitat energy transfers from seagrasses to coral reefs, such exchanges have yet to be quantified. Empirical evidence suggests that grazing by reef-associated herbivores along the coral reef-seagrass interface can be intense (e.g. conspicuous presence of bare-sand halos surrounding coral reefs). This evidence must be interpreted with caution, however, as most of it comes from areas that have experienced sustained, intense overfishing. To quantify the impacts of piscivore removal on cross-habitat energy exchange at the coral reef-seagrass interface, we compared grazing intensity along fished and no-take reefs in the upper and lower Florida Keys. Using visual census techniques and direct measures of seagrass grazing, we documented the impacts of piscivore density on herbivory along the seagrass-coral reef interface. Grazing rates were greater than observed seagrass (Thalassia testudinum) production near reefs in the upper Keys, but
Victoria University of Wellington Viruses are a ubiquitous component of coral reef ecosystems, with several viral types, from at least seven prokaryotic and 20 eukaryotic virus families currently characterised from the surface mucopolysaccharide layer (SML), coral tissue and the water column. However, little is known about the ecology and function of these viruses. For example, what are the environmental drivers of viral abundance and diversity on coral reefs? In this study, the abundance and distribution of virus-like particles (VLPs) associated with the SML and reef water of the coral Montipora capitata were determined using epifluorescence microscopy, while transmission electron microscopy was employed to determine the morphological diversity of VLPs. Sampling was conducted across the Coconut Island Marine Reserve (CIMR) reef system, Kaneohe Bay, Oahu, Hawaii. Viral abundance was correlated with select environmental drivers and prokaryote abundance, while non-metric multidimensional ...
WCS Belize > Wildlife > Caribbean Reef...
The Caribbean Reef Shark is a top predator that spends its entire life in the atoll area, migrating seasonally (May) to feed on spawning snappers. For over 10 years, the population of Caribbean reef shark at Glovers Reef has been monitored by a team led by Dr. Ellen Pikitch and Dr. Demian Chapman, both of Stony Brook University. Long-line sampling of abundance takes place on an annual basis and the results are shared with the WCS Belize staff and the Belize Fisheries Department. All sizes of Caribbean reef shark are found on the ocean reef outside the atoll; only juveniles, however, occur in the deep lagoon inside the atoll. The researches have also been tagging sharks with dart tags, and a few with acoustic tags, to determine movement and use of the various atoll habitats. Results have shown that the atoll is important as a breeding ground for this species. Specific threats include long line fishing and nets as well as all other threats to the health of the atoll. ...

Summer Courses | Education | BIOS - Bermuda Institute of Ocean Sciences
The aim of the Coral Reef Optics (CRO) course is to study the light ecology of coral reef benthic organisms and communities. There are two basic goals: the first is to understand variability in the quantity and quality of light reaching the seafloor and the second is to understand how that light drives fundamental reef processes. The CRO course is an intensive, integrated program comprised of lectures, required reading, laboratory exercises and field surveys. Lectures cover a broad range of relevant topics and ecological principals in coral reef optical ecology including concepts in hydrologic optics, fundamentals of aquatic photosynthesis, and metabolism and calcification of reef organisms and communities. Lectures are supplemented by readings from the primary literature with attention given to active areas of research. The course is divided into evening lectures and discussions (1-2 hours) that are complemented with extensive laboratory and field activities on Bermudas reef system. The ...

Viral Coral | EarthScape
Corals are marine animals in class Anthozoa of phylum Cnidaria typically living in compact colonies of many identical individual polyps. The group includes the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. Scientists have discovered two viruses that appear to infect the single-celled microalgae that reside in corals and are important for coral growth and health, and they say the viruses could play a role in the serious decline of coral ecosystems around the world. These viruses, including an RNA virus never before isolated from a coral, have been shown for the first time to clearly be associated with these microalgae called Symbiodinium. If its proven that they are infecting those algae and causing disease, it will be another step toward understanding the multiple threats that coral reefs are facing. The research was published today in the ISME Journal, in work supported by the National Science Foundation.

The effects of a variable temperature regime on the physiology of the reef-building coral Seriatopora hystrix: results from a...
In order to understand the effects of global climate change on reef-building corals, a thorough investigation of their physiological mechanisms of acclimatization is warranted. However, static temperature manipulations may underestimate the thermal complexity of the reefs in which many corals live. For instance, corals of Houbihu, Taiwan experience up to 10°C changes in temperature over the course of a day during spring tide upwelling events. To better understand the phenotypic plasticity of these corals, a laboratory-based experiment was conducted whereby specimens of Seriatopora hystrix (Dana, 1846) from the upwelling reef, Houbihu, and conspecifics from a non-upwelling reef (Houwan) were exposed to both a stable seawater temperature (26°C) and a regime characterized by a 6°C fluctuation (23-29°C) over a 12 hour period for seven days. A suite of physiological and molecular parameters was measured in samples of both treatments, as well as in experimental controls, in order to determine site ...
Effects of Eutrophication, Seasonality and Macrofouling on the Diversity of Bacterial Biofilms in Equatorial Coral Reefs - ePIC
Biofilms play an important role as a settlement cue for invertebrate larvae and significantly contribute to the nutrient turnover in aquatic ecosystems. Nevertheless, little is known about how biofilm community structure generally responds to environmental changes. This study aimed to identify patterns of bacterial dynamics in coral reef biofilms in response to associated macrofouling community structure, microhabitat (exposed vs. sheltered), seasonality, and eutrophication. Settlement tiles were deployed at four reefs along a cross-shelf eutrophication gradient and were exchanged every 4 months over 20 months. The fouling community composition on the tiles was recorded and the bacterial community structure was assessed with the community fingerprinting technique Automated Ribosomal Intergenic Spacer Analysis (ARISA). Bacterial operational taxonomic unit (OTU) number was higher on exposed tiles, where the fouling community was homogenous and algae-dominated, than in sheltered habitats, which ...
