Posidonia oceanica meadow: a low nutrient high chlorophyll (LNHC) system? (1/38)

BACKGROUND: In spite of very low nutrient concentrations in its vicinity - both column and pore waters-, the Posidonia oceanica of the Revellata Bay displays high biomass and productivity. We measured the nutrient fluxes from the sediment into the water enclosed among the leaf shoots ("canopy water") to determine if it is possible source of nutrients for P. oceanica leaves. RESULTS: During the summer, the canopy water appears to act as a nutrient reservoir for the plant. During that period, the canopy water layer displays both a temperature 0.5 degrees C cooler than the upper water column, and a much higher nutrient content, as shown in this work using a very simple original technique permitting to sample water with a minimal disturbance of the water column's vertical structure. Despite low nutrient concentrations in pore water, mean net fluxes were measured from the sediment to the canopy water. These fluxes are sufficient to provide 20% of the mean daily nitrogen and phosphorus requirement of the P. oceanica shoots. CONCLUSION: An internal cycling of nutrients from P. oceanica senescent leaves was previously noted as an efficient strategy to help face low nutrient availability. The present study points out a second strategy which consists in holding back, in the canopy, the nutrients released at the water-sediment interface. This process occurs when long leaves, during poor nutrient periods in the water column, providing, to P. oceanica, the possibility to develop, high biomass, high chlorophyll quantities in low nutrient environment (a Low Nutrients High Chlorophyll system).  (+info)

Occurrence of sulfated galactans in marine angiosperms: evolutionary implications. (2/38)

We report for the first time that marine angiosperms (seagrasses) possess sulfated polysaccharides, which are absent in terrestrial and freshwater plants. The structure of the sulfated polysaccharide from the seagrass Ruppia maritima was determined. It is a sulfated D-galactan composed of the following regular tetrasaccharide repeating unit: [3-beta-D-Gal-2(OSO3)-1-->4-alpha-D-Gal-1-->4-alpha-D-Gal-1-->3-beta-D-Gal-4(OSO3 )-1-->]. Sulfated galactans have been described previously in red algae and in marine invertebrates (ascidians and sea urchins). The sulfated galactan from the marine angiosperm has an intermediate structure when compared with the polysaccharides from these two other groups of organisms. Like marine invertebrate galactan, it expresses a regular repeating unit with a homogenous sulfation pattern. However, seagrass galactan contains the D-enantiomer of galactose instead of the L-isomer found in marine invertebrates. Like red algae, the marine angiosperm polysaccharide contains both alpha and beta units of D-galactose; however, these units are not distributed in an alternating order, as in algal galactan. Sulfated galactan is localized in the plant cell walls, mostly in rhizomes and roots, indicative of a relationship with the absorption of nutrients and of a possible structural function. The occurrence of sulfated galactans in marine organisms may be the result of physiological adaptations, which are not correlated with phylogenetic proximity. We suggest that convergent adaptation, due to environment pressure, may explain the occurrence of sulfated galactans in many marine organisms.  (+info)

Assessing genetic diversity in clonal organisms: low diversity or low resolution? Combining power and cost efficiency in selecting markers. (3/38)

The increasing use of molecular tools to study populations of clonal organisms leads us to question whether the low polymorphism found in many studies reflects limited genetic diversity in populations or the limitations of the markers used. Here we used microsatellite datasets for two sea grass species to provide a combinatory statistic, combined with a likelihood approach to estimate the probability of identical multilocus genotypes (MLGs) to be shared by distinct individuals, in order to ascertain the efficiency of the markers used and to optimize cost-efficiently the choice of markers to use for deriving unbiased estimates of genetic diversity. These results strongly indicate that conclusions from studies on clonal organisms derived using markers showing low polymorphism, including microsatellites, should be reassessed using appropriate polymorphic markers.  (+info)

An accurate fluorescent assay for quantifying the extent of RNA editing. (4/38)

Recent data suggest that small differences in editing efficiency can have significant functional consequences. Here we present a fluorescent poisoned primer extension assay that is capable of distinguishing editing efficiency differences as low as 5%. For a poison-primer extension assay to be accurate, the extension product must stop at the intended base. Sometimes, however, it runs beyond. We tested the effect of specific enzyme-terminator combinations on the amount of run through. In the worst cases it accounted for 70% of the total signal, and in the best cases <5%. In addition, the specific base can affect run through, with G producing the least. The accuracy of the assay was demonstrated on templates derived from mixed plasmids and then verified on two biological substrates. Using either a K(+) channel mRNA that contains a site for adenosine deamination or an ndhB mRNA that contains a site for cytidine deamination, the editing efficiency predicted by the assay closely matched that predicted by bulk sequencing of individual cDNA clones. This assay should prove useful for analyzing small changes in editing efficiency or for quantifying single nucleotide polymorphisms.  (+info)

Trace metal concentrations in Posidonia oceanica of North Corsica (northwestern Mediterranean Sea): use as a biological monitor? (5/38)

BACKGROUND: Within semi-closed areas like the Mediterranean Sea, anthropic wastes tend to concentrate in the environment. Metals, in particular, are known to persist in the environment and can affect human health due to accumulation in the food chain. The seagrass Posidonia oceanica, widely found in Mediterranean coastal waters, has been chosen as a "sentinel" to quantify the distribution of such pollutants within the marine environment. Using a technique similar to dendrochronology in trees, it can act as an indicator of pollutant levels over a timeframe of several months to years. In the present study, we measured and compared the levels of eight trace metals (Cr, Ni, Cu, Zn, As, Se, Cd, and Pb) in sheaths dated by lepidochronology and in leaves of shoots sampled from P. oceanica meadows collected from six offshore sites in northern Corsica between 1988 and 2004; in the aim to determine 1) the spatial and 2) temporal variations of these metals in these areas and 3) to compared these two types of tissues. RESULTS: We found low trace metal concentrations with no increase over the last decade, confirming the potential use of Corsican seagrass beds as reference sites for the Mediterranean Sea. Temporal trends of trace metal concentrations in sheaths were not significant for Cr, Ni, Cu, As or Se, but Zn, Cd, and Pb levels decreased, probably due to the reduced anthropic use of these metals. Similar temporal trends between Cu levels in leaves (living tissue) and in sheaths (dead tissue) demonstrated that lepidochronology linked with Cu monitoring is effective for surveying the temporal variability of this metal. CONCLUSION: Leaves of P. oceanica can give an indication of the metal concentration in the environment over a short time period (months) with good accuracy. On the contrary, sheaths, which gave an indication of changes over long time periods (decades), seem to be less sensitive to variations in the metal concentration in the environment. Changes in human consumption of metals (e.g., the reduction of Pb in fuel) are clearly reflected in both organs. These results confirm that P. oceanica is a good bioindicator of metals and a good biomonitor species for assessing Cu in the environment.  (+info)

Flower-like terminal structures in racemose inflorescences: a tool in morphogenetic and evolutionary research. (6/38)

Terminal flower-like structures (TFLS) occur in many angiosperms that possess indeterminate inflorescences such as spikes, racemes, or spadices. We describe and review TFLS in early-divergent angiosperms, especially the magnoliid order Piperales and the monocot order Alismatales, in which floral interpretation is controversial. Essentially similar TFLS occur in a wide range of taxa. Among magnoliids, they occur in some Piperales (Saururaceae and a few Piperaceae), but are absent from Chloranthaceae. Among monocots, they occur in some early-divergent families such as Acoraceae, Aponogetonaceae, Juncaginaceae, Potamogetonaceae, and Ruppiaceae. Similar TFLS with obscure organ identity are recorded in mutants of Arabidopsis. TFLS can often be interpreted as pseudanthia (close aggregations of reduced flowers), but in some cases the entire terminal pseudanthium is very similar to a true flower. In some cases, elaborated TFLS could therefore have given rise to what are normally termed 'true' (i.e. euanthial) flowers. Data presented here on terminal pseudanthia in Potamogeton and Ruppia support a pseudanthial evolutionary origin of reproductive units in the alismatid families Zannichelliaceae and Cymodoceaceae. Furthermore, in some alismatid species, either the entire inflorescence apex or an individual primordium at or near the inflorescence tip can be transformed into a filamentous or tubular (or intermediate) structure. A tubular structure enclosing stamens and carpels is described in Piper. This indicates that pseudanthium formation can provoke morphological novelties, perhaps due to new patterns of overlap between expression zones of regulatory genes and/or new spatial constraints.  (+info)

Spectrum of genetic diversity and networks of clonal organisms. (7/38)

Clonal reproduction characterizes a wide range of species including clonal plants in terrestrial and aquatic ecosystems, and clonal microbes such as bacteria and parasitic protozoa, with a key role in human health and ecosystem processes. Clonal organisms present a particular challenge in population genetics because, in addition to the possible existence of replicates of the same genotype in a given sample, some of the hypotheses and concepts underlying classical population genetics models are irreconcilable with clonality. The genetic structure and diversity of clonal populations were examined using a combination of new tools to analyse microsatellite data in the marine angiosperm Posidonia oceanica. These tools were based on examination of the frequency distribution of the genetic distance among ramets, termed the spectrum of genetic diversity (GDS), and of networks built on the basis of pairwise genetic distances among genets. Clonal growth and outcrossing are apparently dominant processes, whereas selfing and somatic mutations appear to be marginal, and the contribution of immigration seems to play a small role in adding genetic diversity to populations. The properties and topology of networks based on genetic distances showed a 'small-world' topology, characterized by a high degree of connectivity among nodes, and a substantial amount of substructure, revealing organization in subfamilies of closely related individuals. The combination of GDS and network tools proposed here helped in dissecting the influence of various evolutionary processes in shaping the intra-population genetic structure of the clonal organism investigated; these therefore represent promising analytical tools in population genetics.  (+info)

Phenols content and 2-D electrophoresis protein pattern: a promising tool to monitor Posidonia meadows health state. (8/38)

BACKGROUND: The endemic seagrass Posidonia oceanica (L.) Delile colonizes soft bottoms producing highly productive meadows that play a crucial role in coastal ecosystems dynamics. Human activities and natural events are responsible for a widespread meadows regression; to date the identification of "diagnostic" tools to monitor conservation status is a critical issue. In this study the feasibility of a novel tool to evaluate ecological impacts on Posidonia meadows has been tested. Quantification of a putative stress indicator, i.e. phenols content, has been coupled to 2-D electrophoretic protein analysis of rhizome samples. RESULTS: The overall expression pattern from Posidonia rhizome was determined using a preliminary proteomic approach, 437 protein spots were characterized by pI and molecular weight. We found that protein expression differs in samples belonging to sites with high or low phenols: 22 unique protein spots are peculiar of "low phenols" and 27 other spots characterize "high phenols" samples. CONCLUSION: Posidonia showed phenols variations within the meadow, that probably reflect the heterogeneity of environmental pressures. In addition, comparison of the 2-D electrophoresis patterns allowed to highlight qualitative protein expression differences in response to these pressures. These differences may account for changes in metabolic/physiological pathways as adaptation to stress. A combined approach, based on phenols content determination and 2-D electrophoresis protein pattern, seems a promising tool to monitor Posidonia meadows health state.  (+info)

When you have the scientific name of a plant, you should easily find information on it with internet search engines, such as google.com. Posidonia oceanica or neptunegrass is a type of seagrass. It is an important native flowering plant forming vast underwater meadows in the Mediterranean Sea. It provides habitat, oxygen, and food for many other organisms. It can grow at a water depth of up to 40 meters. It is endangered by pollution, construction, drag netting, and an introduced algae, Caulerpa taxifolia. Neptunegrass has rhizomes, roots, ribbonlike leaves up to 1.5 meters long, and ball-like fruit. Its fruit and leaves often wash up on beaches. The fruit have air spaces allowing them to float.

With this aim, the density of Paracentrotus lividus was estimated at six different locations around the Gulf of Alghero (Northwestern Sardinia, Italy). At each location, two areas were considered and within each area the number of P. lividus individuals was counted in 10 plots of dimensions 1 × 1 m each. The abundance of P. lividus and Sarpa salpa grazing marks was estimated on two shoots harvested at random in each plot. The number of P. lividus individuals varied greatly among the locations and between areas within each location. A sigmoid function was found to better describe the relation between P. lividus density and the number of its grazing marks. The distance class-frequency distribution of P. lividus grazing marks from the leaf base showed that this herbivore affected the length of the Posidonia oceanica leaf for about 700 mm, and that the attacks were concentrated at the lower portion of the leaf near the base. Conversely, a larger number of the S. salpa grazing bites were more ...

In the Mediterranean Sea, the seagrass Posidonia oceanica is affected by many threats from anthropogenic sources. One of them is the increasing development of fish farming, which is responsible of the destruction of some meadows. Within troubles cause by those fish farms on the surrounding environment, the increase of phytoplankton biomass in the water column (leading to a shading effect) and a modification of the sediment are often cited as a reason of seagrass disappearance. To understand how those troubles are affecting P. oceanica and its sedimentary compartment, in situ experiments were led during three months, from the end of May til the end of August 2009, in STARESO (STAtion de REcherches Sous-marines et Océanographiques, Corsica, France), at ...

Posidonia oceanica is a seagrass endemic to the Mediterranean Sea, and is able to form large monospecific areas, called meadows. These meadows are critical features of the Mediterranean coastal zones, and are of great ecologic and economic importance. Posidonia oceanica meadows shelter high biomasses and biodiversities of amphipod crustaceans. In other temperate meadows, such as Atlantic Zostera marina meadows, the amphipods play an important part in the functioning of the ecosystem, notably in organic matter transfers from producers to higher level consumers. However, the situation in Posidonia oceanica meadows remains unclear, due to the lack of precise studies, and little is known about the trophic ecology of amphipods. In this context, our ...
Temporal variability in species composition and abundance may enhance coexistence in ecological communities, especially when subjected to strong seasonal patterns. Species distribution through time may be related to many factors, such as changes in the structure and functioning of preferred habitats, variations in ecological interactions or asynchronous patterns in species life cycles. Here, data from a one-year survey of amphipod assemblages from a nearly undisturbed Posidonia oceanica meadow are used to investigate the seasonal patterns in species abundance and identity. Our results highlight the presence of a core group of species inhabiting the meadow throughout the year, although an in depth analysis reveals three differentiated seasonal assemblages corresponding to autumn, winter, and a warm season clustering of both spring and summer. The observed patterns suggest the interplay between different mechanisms drives the coexistence of amphipods over the whole year, including niche partitioning,

In the Mediterranean Sea, Posidonia oceanica meadows produce a huge amount of detritus, evaluated up to 300 to 2000 g dry wt m-2 yr-1. This litter is mainly composed of dead leaves but also of uprooted P.oceanica shoots and drift macro-algae from adjacent rocky bottoms. Although rich in refractory materials (lignin) and poor in P and N, these underwater accumulations of leaves are colonised by fungi, micro-algae (like diatoms), bacteria, but also by micro and macrofauna assemblages. These organisms could play an important role in leaf litter degradation and enrichment, but also in energy and carbon transfer from P.oceanica to higher trophic levels in adjacent coastal ecosystems. In this study we focus on the vagile macro-fauna (invertebrates with a size ...
Seagrass are among the most important natural carbon sinks on Earth with Posidonia oceanica (Mediterranean Sea) considered as the most relevant species. Yet, the number of direct measurements of organic carbon burial rates in P. oceanica is still scarce and the effect of local environmental factors remains largely unexplored. In addition, P. oceanica meadows are declining due to the increase in anthropogenic pressure in coastal areas during the last century. The aim of this study is to assess the recent carbon sink capacity of P. oceanica and particularly the effect of human pressure and two environmental factors, water depth and exposure to wave energy (based on a fetch index), on the carbon burial rate since 1900. We conducted an extensive survey of sediment cores in meadows distributed across a gradient of depth, fetch, and human pressure around The Balearic Islands. Sediment and carbon accumulation rates were obtained from 210Pb concentrations profiles. Top-30 centimeters carbon stocks (6.1 ...

The sole species of Butomaceae (the flowering rush family) is the aquatic Eurasian plant Butomus umbellatus, which is listed as moderately invasive in New York. Its first appearance in North America was in the St. Laurence River in 1897, and it is now a problem weed in the Great Lakes.[1]. Studies by L. C. Anderson in 1974 found that the naturalized North American Butomus populations had separate sources. Those east of Niagara Falls, introduced near the St. Lawernce River, originated in eastern Asia. Those west of the Falls were introduced near Detroit, and were from western Euraasia. R. L. Stuckey, in 1994, recognized these two groups as separate species, with B. umbellatus, from western Eurasia, found west of the Falls, and B. junceus, from eastern Asia, found east of the falls.[2] B. junceus is not widely accepted as a separate species at this time, but if it were to be accepted, New Yorks populations would probably be considered to be B. junceus.[3][4]. ...
Posidonia oceanica (Neptune grass) grows at depths varying from 5 to 40-50meters, depending on water clarity. It is endemic to the Mediterranean Sea and forms extensive underwater meadows which can be considered as the Mediterranean underwater equivalent of the tropical forests in land. It sustains a large variety of commercially important species. Both the meadows & the dead leaves of P. oceanica that one can find in the shore are protecting the coastline against erosion. It is particularly sensitive to organic pollution and to bottom trawling. Τhe protection and conservation of P. oceanica habitat is a top priority (EU Habitat Directive 92/43) and everyones responsibility. ...
Rapidly rising atmospheric CO2 concentrations are driving acidification in parallel with warming of the oceans. Future ocean acidification scenarios have the potential to impact coral growth and associated reef function, although reports suggest such affects could be reduced in adjacent seagrass habitats as a result of physio-chemical buffering. To-date, it remains unknown whether these habitats can actually support the metabolic function of a diverse range of corals. Similarly, whether mangroves provide the same ecological buffering service remains unclear. We examine whether reef-associated habitat sites (seagrass and mangroves) can act as potential refugia to future climate change by maintaining favorable chemical conditions (elevated pH and aragonite saturation state relative to the open-ocean), but by also assessing whether the metabolic function (photosynthesis, respiration and calcification) of important reef-building corals are sustained. We investigated three sites in the Atlantic, Indian and

Although biosorption is widely studied topic in chemistry, modelling of biosorption data is based on very old equations. However, use of artificial intelligence in the biosorption based studies can give important clues to researchers.

The maintenance of mobile DNA sequences in clonal organisms has been seen as a paradox. If selfish mobile sequences spread through genomes only by overreplication in transposition, then sexuality is necessary for their spread through populations. The persistence of bacterial transposable elements without obvious dominant selectable markers has previously been explained by horizontal transfer. However, advantageous insertions of mobile DNAs are known in bacteria. Here we model maintenance of an otherwise selfish mobile DNA element in a clonal species in which selection for null mutations occurs during one of two temporally alternating environments. Large areas of parameter space permit maintenance of mobile DNAs where, without selection, they would have gone extinct. Horizontal transfer diminishes, rather than enhances, mean copy number. In finite populations, effective population sizes are greatly reduced by selective sweeps, and mean copy number can be increased as the reduced variance in copy ...

Ive had an Aponogeton crispus flowering steadily for a few months. I usually clip the shoots when they start to annoy me, although it sends a new one to the surface within a day or two (theres no escape for the shoots in a 30 gallon with a glass lid, they just wrap around, and around, at the surface). I left them go (three shoots at once) this time, and noticed seeds for the first time. One of them started to grow, but never dropped off. The shoot turned a dark green color for a quarter inch in either direction (almost looked like an isolated algae problem) and the baby crispus just started growing, about a half inch below the water surface. Ive now taken that section of shoot off of the mother plant (the shoot was starting to decay, anyway). Ive got the section lodged under a wedge of bogwood, so the tiny plant is in more or less direct light but its little roots have access to the substrate. Is this appropriate care? Do baby crispus seem to have particularly high light needs? Is it normal ...

The interesting question is in a non-CO2 tank, does a skimmer dissolve , enough CO2 to avoid decalification? , Louis Lin , TickQuest inc www.tickquest.com Easy enough to try it, see for yourself. All it would do is be a large aeration unit. This seems to work in some planted tanks, such as with marine plants, all of which use bicarbonate, and with tanks with low light or easy faster growing weeds. Plants will grow faster and better with CO2 at lower light and at higher light, but the results might be acceptable to some folks at lower lighting and non CO2 methods. Non CO2 tanks can do fine without aeration to that end...........some to high level with skill and more pateince than many have with CO2 high growth plant tanks. Im not sure why decalification is bad or a problem for a non CO2 tank, is it? Is it hard to measure and resolve if it is? GH/KH kits are easy to use and the rate of removal is relatively slow. I use Onyx, its CaCO3 and traces. That adds some bicarb and Ca, so that issues is ...
Obesity is a serious health concern which triggers other ailments like heart diseases, diabetes, joint ailments, sleep apnea, etc. Obesity is troublesome and its cause goes down to a low nutrient diet and lack of physical activity. For some, it is genetic and hard to control while others develop it with age. Many children become obese while growing up and this is a result of lack of adult guidance during childhood and adolescent years.. Therefore, to keep your child away from this life-threatening medical condition, you need to take steps rather than ignoring the slow transition of your kids towards obesity.. Keep your kids body regulated by incorporating these simple tips:. 1) Inculcate in your kids a habit of eating salad and having some water right before their meals. The good part of this activity is that half their hunger will be fulfilled in eating fibre rich fruits and veggies and having water will keep them hydrated and promote to eat less.. 2) Foster a habit of eating in small ...
Growth and Vegetative Development. Gunawardena, Arunika N. [1], Voicu, Laura [2], Dengler, Nancy G. [2]. Are caspases and ethylene involved in PCD-remodeling of lace place leaves?. The lace plant, Aponogeton madagascariensis, uses programmed cell death (PCD) during leaf development in a quite different way than other plants. PCD remodels the leaves of the lace plant, forming a lattice pattern of equidistantly-positioned perforations at a set time in development. Therefore, lace plant is an attractive model system for studying developmentally-regulated PCD in plants. In this system, discrete populations of cells undergo a disruption of cytoplasmic streaming and loss of anthocyanin, indicators of tonoplast rupture, as well as DNA degradation and other cytoplasmic changes such as formation of vesicles, shrinkage and invagination of the membrane, and degradation of other organelles. Concurrently, adjacent cells are unaffected by these processes and develop normally. Unlike many other forms of plant ...
BACKGROUND: Spirodela polyrhiza is a species of the order Alismatales, which represent the basal lineage of monocots with more ancestral features than the Poales. Its complete sequence of the mitochondrial (mt) genome could provide clues for the understanding of the evolution of mt genomes in plant. METHODS: Spirodela polyrhiza mt genome was sequenced from total genomic DNA without physical separation of chloroplast and nuclear DNA using the SOLiD platform. Using a genome copy number sensitive assembly algorithm, the mt genome was successfully assembled. Gap closure and accuracy was determined with PCR products sequenced with the dideoxy method. CONCLUSIONS: This is the most compact monocot mitochondrial genome with 228,493 bp. A total of 57 genes encode 35 known proteins, 3 ribosomal RNAs, and 19 tRNAs that recognize 15 amino acids. There are about 600 RNA editing sites predicted and three lineage specific protein-coding-gene losses. The mitochondrial genes, pseudogenes, and other hypothetical ...

Molecular dating was performed using a Bayesian method (Beast 1.4.8; Drummond & Rambaut 2007; see electronic supplementary material for methodological details). Two to three calibration points were specified. In each case, a normal prior was used, and its mean and standard deviations were set in such a way that 95 per cent confidence intervals corresponded to the upper and lower bounds of each calibration point. In this way, uncertainty concerning the exact dates of the calibration points could be accounted for. The age of the oldest syngnathid fossils (Monte Bolca formation, Early Eocene) (Patterson 1993; Bellwood 1996) was used as the first calibration point. These fossils date from the boundary between the Ypresian and Lutetian ages (approx. 48-50 Myr). To account for the possibility that they are younger than the origin of the family, we specified the beginning of the Eocene as an upper bound (mean = 52.2, s.d. = 2.3, 95% confidence interval: 48-56). The other two calibration points were ...
Seagrasses play a vital role in the survival of many marine animals, which use their meadows as habitat and feeding areas. But environmental pollution, such heavy metal, is contributing to the decline of seagrasses in some areas.. PhD candidate, Ms Nasim Shah Mohammadi from the UTS Climate Change Cluster (C3), is investigating Zostera mulleri, an endangered species of seagrass native to the southern half of Australia, and found mostly in the protected waters of NSW.. "My study aims to estimate the gene diversity and resilience of the remaining Z. mulleri so as to better understand the decline of seagrass meadows in Australia," Ms Shah Mohammadi said.. All seagrasses, including Zostera muuleri, are crucial to biodiversity as they contribute organic matter to food chains and help maintain water quality by stabilising sediment.. Ms Shah Mohammadi was recently awarded a $1000 grant from the Linnean Society of NSW, which will help further her research into the molecular investigation of Z. ...
Natural disturbances, such as grazing, storms, ice-scouring, and desiccation, are an inherent part of seagrass ecosystem dynamics. Seagrasses display an extraordinarily high degree of phenotypic plasticity, adapting rapidly to changing environmental conditions.. Seagrasses are in global decline, with some 30,000 km2 (12,000 sq mi) lost during recent decades. The main cause is human disturbance, most notably eutrophication, mechanical destruction of habitat, and overfishing. Excessive input of nutrients (nitrogen, phosphorus) is directly toxic to seagrasses, but most importantly, it stimulates the growth of epiphytic and free-floating macro- and micro-algae. This weakens the sunlight, reducing the photosynthesis that nourishes the seagrass and the primary production results.. Decaying seagrass leaves and algae fuels increasing algal blooms, resulting in a positive feedback. This can cause a complete regime shift from seagrass to algal dominance. Accumulating evidence also suggests that ...
Algae live inside marine animals. Coral tissues host several million algae per square inch, and these marine plants provide 90 percent of nutrients needed by the coral. The symbiotic relationship is based on a cycle of coral enzymes which cause algae to release carbohydrates and algae to receive nitrogen from coral waste. Algae are shaded from intense sunlight by coral pigments ...

An Australian invention is dramatically improving the marine health of one of Queenslands busiest waterways, Moreton Bay.. Newly-designed boat moorings are protecting endangered seagrass habitats, bringing native marine animals like dugongs back in herds.. Moreton Bay is home to the largest population of dugongs living near an urban centre but about 15 per cent of their food source in the bay has been scratched away from boat chain moorings.. That is similar to an area roughly the size of 90 football fields.. Joel Bolzenius from environmental group South East Queensland Catchments says the threat to the food source of hundreds of species is ever-growing.. "Boat moorings weve seen over the decades - the number of moorings and the number of boats - actually increase," he said. About 1,000 dugongs call Moreton Bay home.. Dr Janet Lanyon from the University of Queensland has been studying Australias dugong species for 30 years.. She says maintaining a stable food source for the mammals is ...

Field and laboratory experiments were performed to investigate the palatability to predatory fishes of organic extracts of the Caribbean ascidian Didemnum conchyliatum. This tan-colored compound ascidian grows as an epibiont on seagrass blades. A dichloromethane/methanol extract of the ascidian incorporated into carrageenan food strips at the same volumetric concentration as the extract occurred in the ascidian tissues deterred feeding of a natural assemblage of consumers in the same seagrass beds from which the ascidians were collected. Bioassay-directed fractionation of this extract revealed that the deterrent property was restricted to fractions containing novel indole-maleimide-imidazole alkaloids, didemnimides A to D. Laboratory assays of purified metabolites revealed that didemnimides C and D deterred feeding by a generalist predatory reef fish, but that didemnimides A and B were not deterrent. Only didemnimide D deterred feeding in the field; neither didemnimide C nor the fraction ...

Due to widespread and continuing seagrass loss, restoration attempts occur worldwide. This article presents a geospatial modeling technique that ranks the suitability of sites for restoration based on light availability and boating activity, two factors cited in global studies of seagrass loss and restoration failures. The model presented here was created for Estero Bay, Florida and is a predictive model of light availability and boating pressure to aid seagrass restoration efforts. The model is adaptive and can be parameterized for different locations and updated as additional data is collected and knowledge of how factors impact seagrass improves. Light data used for model development were collected over one year from 50 sites throughout the bay. Coupled with high resolution bathymetric data, bottom mean light availability was predicted throughout the bay. Data collection throughout the year also allowed for prediction of light variability at sites, a possible indicator of seagrass growth and ...

Seagrass ecosystems have recently been identified for their role in climate change mitigation due to their globally-significant carbon sinks; yet, the capacity of seagrasses to sequester carbon has been shown to vary greatly among seagrass ecosystems. The recalcitrant nature of seagrass tissues, or the resistance to degradation back into carbon dioxide, is one aspect thought to influence sediment carbon stocks. In this study, a global survey investigated how the macromolecular chemistry of seagrass leaves, sheaths/stems, rhizomes and roots varied across 23 species from 16 countries. The goal was to understand how this seagrass chemistry might influence the capacity of seagrasses to contribute to sediment carbon stocks. Three non-destructive analytical chemical analyses were used to investigate seagrass chemistry: thermogravimetric analysis and solid state 13C-NMR and infrared spectroscopy. A strong latitudinal influence on carbon quality was found, whereby temperate seagrasses contained 5% relatively
Many clonal organisms occasionally outcross, but the long-term consequences of such infrequent events are often unknown. During five years, representing three to five plant generations, we followed 16 experimental field populations of the forb, Oenothera biennis, originally planted with the same 18 original genotypes. Oenothera biennis usually self-fertilizes, which due to its genetic system (Permanent Translocation Heterozygosity), results in seeds that are clones of the maternal plant. However, rare outcrossing produces genetically novel offspring (but without recombination or increased heterozygosity). We sought to understand whether novel genotypes produced through natural outcrossing had greater fecundity or different multigenerational dynamics compared to our original genotypes. We further assessed whether any differences in fitness or abundances through time between original and novel genotypes were exaggerated in the presence versus absence of insect herbivores. Over the course of the ...
Coastal waters of the Great Barrier Reef (GBR) are contaminated with agricultural pesticides, including the photosystem II (PSII) herbicides which are the most frequently detected at the highest concentrations. Designed to control weeds, these herbicides are equally potent towards non-target marine species, and the close proximity of seagrass meadows to flood plumes has raised concerns that seagrasses may be the species most threatened by herbicides from runoff. While previous work has identified effects of PSII herbicides on the photophysiology, growth and mortality in seagrass, there is little comparative quantitative toxicity data for seagrass. Here we applied standard ecotoxicology protocols to quantify the concentrations of four priority PSII herbicides that inhibit photochemistry by 10, 20 and 50% (IC10, IC20 and IC50) over 72 h in two common seagrass species from the GBR lagoon. The photosystems of seagrasses Zostera muelleri and Halodule uninervis were shown to be generally more ...

Introduction Marine turtles are important components of the Sulu-Sulawesi Marine Ecoregion, (SSME). Green turtles are important for maintaining healthy seagrass beds and coral reefs. Without constant grazing, seagrass beds may become overgrown, obstructing currents, shading the bottom, or decomposing. Seagrass beds in turn are nurseries for a number of species of commercial fish and crustaceans, including shrimp. On coral reefs, green turtles crop algae that can compete with corals. Hawksbill turtles control the population of sponges in coral reefs, which can easily out-compete corals for the same space. Through selective foraging, hawksbill turtles are able to impact the overall reef diversity. Leatherback turtles eat large quantities amounts of jellyfish, helping to keep their populations under control. Jellyfish prey on larval fish, many species of which are economically important to humans. Loggerhead turtles are known to help recirculate sediments on the seabed and distribute nutrients ...
In three stories or editorials (May 19th 29th and 30th, 2015) the Bradenton Herald wrote about the tremendous recovery in seagrass beds in Tampa Bay - news all Floridians should be absolutely thrilled about. A reading of these pieces includes far more than a suggestion that there is a cause-and-effect connection between the seagrass bed recoveries and the fertilizer blackout component of the relevant fertilizer ordinances passed in the region (Pinellas-2010; City of Tampa-2011; Manatee-2011).. Confessing that this blog advocates for the Green Industries (turfgrass, landscape, golf, professional lawn care, etc.), and that I have strong feelings about personal property rights, Ill defer offering my own assessment of those editorial suggestions. Instead, let me use the information offered by the Tampa Bay Estuary Program (TBEP) itself.. The following comes from an article published on TBO.com on March 22, 2014. In that article, the TBEP was attributed as stating that 34,642 acres of seagrass beds ...
The Memorandum of Understanding on the Conservation and Management of Dugongs and their Habitats throughout their Range (Dugong MOU) aims to promote internationally coordinated actions to ensure the long-term survival of dugongs and their seagrass habitats throughout their extensive range. The MOU entered into effect on 31 October 2007 in Abu Dhabi, United Arab Emirates. The Dugong MOU is administered by a Secretariat based in Abu Dhabi alongside the Raptors MoU Coordinating Unit at the CMS Office - Abu Dhabi.
The export of the calcitic platelets (coccoliths) of coccolithophores to the sea floor acts as a long-term sink of carbon. In order to understand the effects of current ocean acidification on coccolithophore calcification, it is important to estimate the amount of calcite that is bound in single coccoliths, which - due to their minuteness (1-10 μm) - cannot be individually weighed. To estimate single coccolith weights, this study takes advantage of the birefringence method (Beaufort, 2005), which links the interference color of calcite under polarized light with calcite thickness. Two similar techniques, one using crossed-polarized light (XPL) and one using circular polarized light (CPL), were tested to compare coccolith weight estimates of cultured single clones of Gephyrocapsa oceanica, which - in a previous study (Rickaby et al., 2010) - were grown in increasing concentrations of dissolved inorganic carbon (DIC) but constant pH-levels (~8.1) to reflect long-term buffering of the ocean. In ...
Seagrasses are one of the most productive and economically important habitats in the coastal zone, but they are disappearing at an alarming rate, with more than half the worlds seagrass area lost since the 1990s. They now face serious threat from climate change, and there is much current speculation over whether they will survive the coming decades. The future of seagrasses depends on their ability to recover and adapt to environmental change-i.e. their resilience. Key to this, is understanding the role that genetic diversity plays in the resilience of this highly clonal group of species. To investigate population structure, genetic diversity, mating system (sexual versus asexual reproduction) and patterns of connectivity, we isolated and characterised 23 microsatellite loci using next generation sequencing for the Australian seagrass species, Zostera muelleri (syn. Z. capricorni), which is regarded as a globally significant congeneric species. Loci were tested for levels of variation based ...
Pollen grain on a chip. Scanning electron micrograph (SEM) of a pollen grain from an Aponogeton sp. plant on a digital camera chip. Pollen grains are reproductive structures produced by the male parts of flowering plants. The grain has a spiked outer wall (exine), which may assist in its dispersal by improving its adherence to pollinating insects. Aponogeton sp. plants are aquatic and are found in tropical to warm temperate regions of Africa, Asia and Australasia. - Stock Image C002/6224
A lace wig, also called a lace unit, hair system or cranial hair prosthetic, are hair extensions that create the illusion that hair is growing out of ones scalp, and therefore is one of the most natural looking extensions on the market. This is achieved by the method of the lace wig construction. A fine lace material is used as the base where individual hairs are meticulously hand tied onto the lace.. The term full lace denotes that the base cap is made fully of lace, while lace front wigs have lace in front and different materials at the back of the cap. One is also able to purchase a lace frontal hair piece that can be used with weaving wefts. With this arrangement, the wefts are glued or sewn into ones hair and the lace frontal applied only at the hairline.. There are typically two types of lace materials used to make the base cap- Swiss and French lace. Swiss lace is very fine and delicate and is the most undetectable choice. Though French lace is not as undetectable (but also ...

Temperate and tropical seagrasses are susceptible to wasting disease outbreaks caused by pathogenic protists of the genus Labyrinthula. Even though there is an increasing awareness of the environmental conditions that influence the etiology of seagrass-. Labyrinthula disease dynamics, the biochemical basis of seagrass defense responses, in particular chemical defenses, is still vastly understudied. Using an in vitro bioassay, we provide evidence that previously characterized phenolic and potentially novel, undescribed non-phenolic metabolites derived from Thalassia testudinum Banks ex Konig exhibit anti-labyrinthulid activity. All phenolic compounds tested displayed dose-dependent behavior and selected combinations interacted synergistically. The flavone glycoside thalassiolin B was roughly 20-100 times more active than any phenolic acid tested. Based upon values reported in the literature, it was calculated that infected specimens of T. testudinum contain natural concentrations of phenolic ...

Some of these mutations give cells an edge over other cells. Selective pressure means that cells with certain characteristics "win" the survival of fittest battle within the tumor. The result is that different "neighborhoods" of the tumor will be populated with clones of the fittest cells. Perhaps one region of the tumor is low in nutrients; it will contain cells that have picked up mutations to survive in a low nutrient environment. Another region might be under constant exposure to the bodys immune system; it will contain cells with immune evasion mutations. This is how differences within tumors emerge, and this diversity is also one reason why each patients tumor is unique, and subsequently why their tumors vulnerability to therapy is different, too.. This genomic instability also exists between patients. A combination of random chance and differences in the genome lead to unique tumors to develop in each patient. Lets say, for example, that we are looking at a group of breast cancer ...

Choerodon cyanodus is a demersal species and is abundant in shallow waters in Shark Bay (, 10 m). It has been captured in waters up to 30 m deep along the Pilbara/Kimberley coast of Western Australia (Newman et al. 2003). It is found on flat bottoms and coral reefs (Allen 1999). However, it is common on rocky limestone reefs, weedy-rock areas, rocky shorelines and seagrass areas in Shark Bay (Travers and Potte 2002, Fairclough, in prep.). Juveniles and adults (, ca. 200 mm) are found in weedy rock or seagrass habitats, but fish above this size are more common on reefs or rocky habitats (Fairclough in prep.). While records suggest that this species reaches 70 cm in length and recreational fishing records suggest a specimen weighing 4.5 kg was captured in Shark Bay (Australian Anglers Association, (WA Division) Inc. 2003), the majority of fish collected in Shark Bay during current research were below 30 cm and none were collected above 40 cm (Fairclough, in prep.). All fish collected by Choat ...
In Laguna Madre, Texas, USA, a monospecific brown tide bloom began in January 1990 and was still persisting at the time of this writing. Immediately following the start of the bloom, abundance, biomass and diversity of benthos declined, and have remained low for 6 yr. One explanation for the decline is that the brown tide organism is a poor food source. To determine whether the brown tide was incorporated into the estuarine food web, benthic invertebrates and fish were studied 14 mo after the bloom onset using stable carbon isotope ratios. Fish and benthos were collected from 2 areas, a seagrass habitat in Laguna Madre, and a muddy bottom habitat in the adjacent Alazan Bay. The muddy bottom fauna had a strong brown tide signature, indicating the incorporation of brown tide or brown tide detritus into the food web. The higher-biomass seagrass-fauna had heavier isotope values, reflecting incorporation of seagrass carbon in addition to brown tide. The top predators, Sciaenops ocellatus and Pogonias ...
The Nannochloropsis genus contains oleaginous microalgae that have served as model systems for developing renewable biodiesel. Recent genomic and transcriptomic studies on Nannochloropsis species have provided insights into the regulation of lipid production in response to nitrogen stress. Previous studies have focused on the responses of Nannochloropsis species to short-term nitrogen stress, but the effect of long-term nitrogen deprivation remains largely unknown. In this study, physiological and proteomic approaches were combined to understand the mechanisms by which Nannochloropsis oceanica IMET1 is able to endure long-term nitrate deprivation and its ability to recover homeostasis when nitrogen is amended. Changes of the proteome during chronic nitrogen starvation espoused the physiological changes observed, and there was a general trend toward recycling nitrogen and storage of lipids. This was evidenced by a global down-regulation of protein expression, a retained expression of proteins ...
Bobgunnia madagascariensis (Bambara: Samagara), also called the snake bean plant, is a species of legume in the Fabaceae family. Bobgunnia madagascariensis is a small deciduous tree, 3-4 m tall. The plant has large pods that turn dark when ripe. The larvae of Abantis zambesiaca feed on B. madagascariensis. Bobgunnia madagascarensis is toxic. Poison composed of the roasted seeds of Bobgunnia madagascariensis and innards of the beetle Diamphidia nigroornata is applied to the arrows of the Bushmen.[citation needed] Seeds, fruits and stem bark are also used in fishing by poisoning in Africa. The methanolic extract of the fruit of B. madagascariensis contains a saponin tetraglycoside. The root bark of B. madagascariensis contains quinone methide diterpenes. The seed pod contains two acidic saponins, swartziasaponin A and B and swartziagenin, a mixture of oleanolic and 0-acetyloleanolic acid. The pod methanolic extract yields highly glycosylated flavonoids (glycosides of kaempferol and quercetin). The ...

The Cabo de Gata Sierra is one of the main European volcanic mountain massifs. It stretches to the coast with cliffs over 100 m high, edged with salt flats and chains of fixed sand dunes. The coastal shelf is well conserved with vast underwater meadows of Posidonia and benthic communities associated with the scantly illuminated rocky seabed. The climate is conditioned by the proximity of the Sahara Desert and the influence during most of the year of the Azores anticyclone. The result is high temperatures and scant and irregular rainfall. The Biosphere Reserve hosts an abundance of semi arid plant formations with fan palms (the only autochthonous continental European palm tree),Pistacia lentiscus, Olea europaea var sylvestris and the Indian Jujub (Zizyphus jujube). Together with numerous endemic species specific to the zone are many other species characteristic of Saharan flora. In the dunes and sand flats vegetation adapted to saline soils has developed, including European Beach-grass, ...
