Zooplankton: Minute free-floating animal organisms which live in practically all natural waters.Cladocera: A suborder of CRUSTACEA, order Diplostraca, comprising the water fleas. They are benthic filter feeders that consume PHYTOPLANKTON. The body is laterally compressed and enclosed in a bivalved carapace, from which the head extends.Copepoda: A huge subclass of mostly marine CRUSTACEA, containing over 14,000 species. The 10 orders comprise both planktonic and benthic organisms, and include both free-living and parasitic forms. Planktonic copepods form the principle link between PHYTOPLANKTON and the higher trophic levels of the marine food chains.Daphnia: A diverse genus of minute freshwater CRUSTACEA, of the suborder CLADOCERA. They are a major food source for both young and adult freshwater fish.Phytoplankton: Free-floating minute organisms that are photosynthetic. The term is non-taxonomic and refers to a lifestyle (energy utilization and motility), rather than a particular type of organism. Most, but not all, are unicellular algae. Important groups include DIATOMS; DINOFLAGELLATES; CYANOBACTERIA; CHLOROPHYTA; HAPTOPHYTA; CRYPTOMONADS; and silicoflagellates.Rotifera: A class of minute animals of the phylum Aschelminthes.Food Chain: 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.Fresh Water: Water containing no significant amounts of salts, such as water from RIVERS and LAKES.Lakes: Inland bodies of still or slowly moving FRESH WATER or salt water, larger than a pond, and supplied by RIVERS and streams.Eutrophication: The enrichment of a terrestrial or aquatic ECOSYSTEM by the addition of nutrients, especially nitrogen and phosphorus, that results in a superabundant growth of plants, ALGAE, or other primary producers. It can be a natural process or result from human activity such as agriculture runoff or sewage pollution. In aquatic ecosystems, an increase in the algae population is termed an algal bloom.Predatory Behavior: Instinctual behavior pattern in which food is obtained by killing and consuming other species.Ponds: Inland bodies of standing FRESHWATER usually smaller than LAKES. They can be man-made or natural but there is no universal agreement as to their exact size. Some consider a pond to be a small body of water that is shallow enough for sunlight to reach the bottom.Plankton: Community of tiny aquatic PLANTS and ANIMALS, and photosynthetic BACTERIA, that are either free-floating or suspended in the water, with little or no power of locomotion. They are divided into PHYTOPLANKTON and ZOOPLANKTON.Population Dynamics: The pattern of any process, or the interrelationship of phenomena, which affects growth or change within a population.Ecosystem: A functional system which includes the organisms of a natural community together with their environment. (McGraw Hill Dictionary of Scientific and Technical Terms, 4th ed)Biomass: Total mass of all the organisms of a given type and/or in a given area. (From Concise Dictionary of Biology, 1990) It includes the yield of vegetative mass produced from any given crop.Population Density: Number of individuals in a population relative to space.Elasmobranchii: A subclass of cartilaginous fish comprising the SHARKS; rays; skates (SKATES (FISH);), and sawfish. Elasmobranchs are typically predaceous, relying more on smell (the olfactory capsules are relatively large) than sight (the eyes are relatively small) for obtaining their food.Animal Population Groups: Animals grouped according to ecological, morphological or genetic populations.Biodiversity: The variety of all native living organisms and their various forms and interrelationships.Fishes: A group of cold-blooded, aquatic vertebrates having gills, fins, a cartilaginous or bony endoskeleton, and elongated bodies covered with scales.Seasons: Divisions of the year according to some regularly recurrent phenomena usually astronomical or climatic. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)Oceans and Seas: A great expanse of continuous bodies of salt water which together cover more than 70 percent of the earth's surface. Seas may be partially or entirely enclosed by land, and are smaller than the five oceans (Atlantic, Pacific, Indian, Arctic, and Antarctic).Crustacea: A large subphylum of mostly marine ARTHROPODS containing over 42,000 species. They include familiar arthropods such as lobsters (NEPHROPIDAE), crabs (BRACHYURA), shrimp (PENAEIDAE), and barnacles (THORACICA).Water Pollution, Chemical: Adverse effect upon bodies of water (LAKES; RIVERS; seas; groundwater etc.) caused by CHEMICAL WATER POLLUTANTS.Scenedesmus: A genus of GREEN ALGAE in the family Scenedesmaceae. It forms colonies of usually four or eight cylindrical cells that are widely distributed in freshwater and SOIL.Marine Biology: The study of the origin, structure, development, growth, function, genetics, and reproduction of organisms which inhabit the OCEANS AND SEAS.Aquabirnavirus: A genus of RNA viruses in the family BIRNAVIRIDAE infecting fish, mollusks, and crustaceans. It is transmitted both vertically and horizontally with no known vectors. The natural hosts are salmonids and the type species is INFECTIOUS PANCREATIC NECROSIS VIRUS.Atlantic OceanArtemia: A genus of CRUSTACEA of the order ANOSTRACA, found in briny pools and lakes and often cultured for fish food. It has 168 chromosomes and differs from most crustaceans in that its blood contains hemoglobin.Anostraca: An order of CRUSTACEA comprised of shrimp-like organisms containing body trunks with at least 20 segments. The are commonly used as aquarium food.Micronesia: The collective name for islands of the Pacific Ocean east of the Philippines, including the Mariana, PALAU, Caroline, Marshall, and Kiribati Islands. (From Webster's New Geographical Dictionary, 1988, p761 & Room, Brewer's Dictionary of Names, 1992, p350)Harmful Algal Bloom: An algal bloom where the algae produce powerful toxins that can kill fish, birds, and mammals, and ultimately cause illness in humans. The harmful bloom can also cause oxygen depletion in the water due to the death and decomposition of non-toxic algae species.Scyphozoa: The class of true jellyfish, in the phylum CNIDARIA. They are mostly free-swimming marine organisms that go through five stages in their life cycle and exhibit two body forms: polyp and medusa.Seawater: The salinated water of OCEANS AND SEAS that provides habitat for marine organisms.Feeding Behavior: Behavioral responses or sequences associated with eating including modes of feeding, rhythmic patterns of eating, and time intervals.Water Movements: The flow of water in enviromental bodies of water such as rivers, oceans, water supplies, aquariums, etc. It includes currents, tides, and waves.Water Microbiology: The presence of bacteria, viruses, and fungi in water. This term is not restricted to pathogenic organisms.Mediterranean SeaBrazilMaineFatty Acids, Essential: Long chain organic acid molecules that must be obtained from the diet. Examples are LINOLEIC ACIDS and LINOLENIC ACIDS.Coral Reefs: Marine ridges composed of living CORALS, coral skeletons, calcareous algae, and other organisms, mixed with minerals and organic matter. They are found most commonly in tropical waters and support other animal and plant life.Carotenoids: The general name for a group of fat-soluble pigments found in green, yellow, and leafy vegetables, and yellow fruits. They are aliphatic hydrocarbons consisting of a polyisoprene backbone.Anthozoa: A class in the phylum CNIDARIA, comprised mostly of corals and anemones. All members occur only as polyps; the medusa stage is completely absent.WyomingNautilus: The sole genus in the family Nautilidae, order Nautilida, comprised of CEPHALOPODS with spiral external shells that are separated into chambers.Oncorhynchus: A genus of the family SALMONIDAE (salmons and trouts). They are named for their hooked (onco) nose (rhynchus). They are usually anadromous and occasionally inhabit freshwater. They can be found in North Pacific coastal areas from Japan to California and adjacent parts of the Arctic Ocean. Salmon and trout are popular game and food fish. Various species figure heavily in genetic, metabolism, and hormone research.Raptors: BIRDS that hunt and kill other animals, especially higher vertebrates, for food. They include the FALCONIFORMES order, or diurnal birds of prey, comprised of EAGLES, falcons, HAWKS, and others, as well as the STRIGIFORMES order, or nocturnal birds of prey, which includes OWLS.Trout: Various fish of the family SALMONIDAE, usually smaller than salmon. They are mostly restricted to cool clear freshwater. Some are anadromous. They are highly regarded for their handsome colors, rich well-flavored flesh, and gameness as an angling fish. The genera Salvelinus, Salmo, and ONCORHYNCHUS have been introduced virtually throughout the world.Hot Springs: Habitat of hot water naturally heated by underlying geologic processes. Surface hot springs have been used for BALNEOLOGY. Underwater hot springs are called HYDROTHERMAL VENTS.

Copepod6
  • In total, 325 Barcode Index Numbers (BINs) were detected with only three BINs (two cladocerans and one copepod) shared between Canada and Mexico, suggesting a much narrower distribution range of freshwater zooplankton than previously thought. (ecosur.mx)
  • 84±19 fmol CH 4 copepod −1 d −1 ) dominated zooplankton communities, and (3) methane was only produced on a Rhodomonas sp. (biogeosciences.net)
  • Furthermore, copepod-specific methane production rates increased with incubation time. (biogeosciences.net)
  • Lipid biomarkers extracted from phytoplankton- and copepod-rich samples revealed that Dinophyceae are a major food source of the T. longicornis dominated zooplankton community, supporting the proposed link between copepod grazing, DMSP/DMSO release, and the build-up of subthermocline methane enrichments in the central Baltic Sea. (biogeosciences.net)
  • We here show that the provision with the biochemical complex thiamin (vitamin B 1 ) to the common phytoplankton Rhodomonas baltica altered its fatty acid (FA) pattern toward ω3-highly-unsaturated FAs (ω3-HUFA) and that this pattern was further transferred up to the zooplankton consumer, the copepod Acartia tonsa . (frontiersin.org)
  • In the western subarctic Pacific, zooplankton community was dominated by large-sized copepod Neocalanus spp. (nii.ac.jp)

Bacteria6
  • However, research on pathogenic and nonpathogenic bacteria has shown that direct association with zooplankton has significant influences on the bacteria's physiology and ecology. (pnas.org)
  • We used stratified migration columns to study vertical dispersal of hitchhiking bacteria through migrating zooplankton across a density gradient that was otherwise impenetrable for bacteria in both upward and downward directions (conveyor-belt hypothesis). (pnas.org)
  • Some part of methane gas is consumed by the anaerobic methane oxidation bacteria which in turn works as food source to the zooplankton . (wikipedia.org)
  • Bacteria associated with zooplankton also increase. (who.int)
  • Thus, in addition to heterotrophic bacteria and phytoplankton, zooplankton may also use the particulate fraction of peat layer t-OM (t-POM) as a potential food source in those systems. (diva-portal.org)
  • a traditional system based on simple fertilization to improve microalgae concentration (control), an autotrophic system (AS) based on the promotion of biofloc and biofilm by the addition of fertilizer and artificial substrates and a heterotrophic system (HS) based on the promotion of heterotrophic bacteria by the addition of nitrogenous and carbonaceous sources and artificial substrates.

Taxa1
  • By tracing the evolution of aggregating, blooming, and swarming phenotypes, organismal traits, and environmental settings on an up-to-date synoptic phylogeny of classes and orders of Medusozoa, we are able to hypothesize circumstances that enable taxa to occur en masse . (springer.com)
Ecosystem7
  • Using municipal fisheries data and interviews with stakeholders in coastal Maine, it describes a suite of both direct and indirect benefits: a reversal of the "shifting baselines syndrome" and a motivation to manage fisheries sustainably, diversification of local economies and fisheries, community building and an increased sense of local pride, a demographic broadening of the conservation community, and enhanced ecosystem services and recreational opportunities. (ecologyandsociety.org)
  • Adult Calanus finmarchicus , which is a key indicator species for ecosystem status in the Gulf of Maine, has recently increases after a period of lower values in the 1990's. (noaa.gov)
  • Long time-series measurements, as well as research on large-scale ocean processes, are the key to improving our understanding of ecosystem shifts,' says Mary Elena-Carr, program director in NSF's biological oceanography program. (nsf.gov)
  • During the Ordovician the level of ecosystem complexity increased globally strongly and organismal ecospace utilization intensified significantly [3,. (plos.org)
  • Zooplanktons are microscopic free swimming animals which represent a major part of aquatic fauna and are known to be indispensable link between the primary producers and consumers of Lake Ecosystem. (omicsonline.org)
  • Bio-monitoring of the lake ecosystem includes the study of phytoplanktons, zooplanktons, macrophytes, macro-micro benthos and tertiary consumers. (omicsonline.org)
  • As the Arctic Ocean becomes easier to navigate, increased traffic and pollution could further damage the ecosystem. (greenpeace.org)

Organisms6
  • Better utilization of natural forage organisms (i.e., zooplankton) and reducing the residence time of fry in the hatchery may be ways to improve fry production efficiency. (usda.gov)
  • Increases in carbon dioxide are in turn acidifying the oceans and inhibiting the ability of many marine organisms to form UV-absorbing exoskeletons. (rsc.org)
  • At night, the phytoplankton themselves, the zooplankton and the decomposer organisms living on dead organic matter are all respiring and consuming oxygen. (nottingham.ac.uk)
  • The presence of biofilm and bioflocs composed by either autotrophic or heterotrophic organisms in combination with formulated feed improved the growth performance and survival of shrimp. (hindawi.com)
  • Up today, organisms from zooplankton communities have been the most used as natural feed for aquaculture purposes [ 6 - 8 ]. (hindawi.com)
  • Microbiota has been used mostly as probiotic to improve the health status of the farmed organisms, or to maintain adequate environmental conditions within the culture units [ 9 ]. (hindawi.com)

  • There was then a rapid increase until about 1985 when a gradual decrease started. (noaa.gov)
  • In addition, besides a decrease in saturated FAs, especially an increase in HUFA in A. aurita polyps with decreasing temperature was observed, for which the dietary provision with HUFA seemed to be critical. (frontiersin.org)
