Daphnia. Daphnia (also known as water flea) is a genus of small planktonic crustaceans. The daphnia body is usually 0.2-3 millimeters long, which is pretty tiny compared to their cousins in the Class Crustaceans like crabs and lobsters. Daphnia is too small and weak to live in a strong current, which they cannot swim against In taxonomy, it is important to maintain chronological order in taxon naming and understanding. Here, I confirm that according to the rules of Zoological Nomenclature, Carl Linnaeus must be regarded as the author of two common cladoceran taxa, Daphnia pulex (Linnaeus, 1758) and Polyphemus pediculus (Linnaeus, 1758)

Galeata genetically affects the native species Daphnia galeata mendotae through hybridization; hybrid forms of these two species are much more successful than the North American species representing 90-100% of swarms in lakes where hybrids are present (Taylor and Hebert. Daphnia is another high quality live food that's very nutritious for fish. There are many species of daphnia (Pulex, Magna, etc.), I have found that the Red Russian Magna daphnia are about the largest and seem very hardy. However, daphnia cultures can crash for unknown/unseen reasons. In general, daphnia are very sensitive to water quality The two most readily available species of Daphnia are D. pulex (small and most common) and D. magna (large). They are often associated with a related genus in the order Cladocera: Moina, which is in the Moinidae family instead of Daphniidae and is much smaller than D. pulex (approximately half the maximum length) A few species are marine, but generally Daphnia, including Daphnia pulex, are freshwater organisms. Why is Daphnia a model organism? In this genomic era, Daphnia is an important model system for crustaceans and freshwater organisms due to the availability of its whole genome sequence and microarrays (Colbourne et al. 2011) Daphnia pulex is an easy-to-grow food source for hydra and small fish.

Moina macrocopa are commonly found in stagnant or very slow moving water that contains large amounts of decomposing organic material About Daphnia [edit | edit source]. Daphnia (Daphnia pulex, moina, magna, or a hybrid) are small, mostly planktonic, crustaceans, between 0.2 and 5 mm in length depending on species. Daphnia are members of the order Cladocera, and are one of the several small aquatic crustaceans commonly called water fleas because of their jumping style (although fleas are insects and thus only very distantly. Several genetic lineages of obligate parthenogenetic Daphnia pulex, a common zooplankton species, have invaded Japan from North America. Among these, a lineage named JPN1 is thought to have started colonization as a single genotype several hundred to thousand years ago.. Daphnia are a very good food for fry from about two weeks onwards. The adults are too big for the fry to eat, but the larvae of the D.Pulex variety are an ideal size. To ensure enough are available when you need them, the best solution is to prepare your own pond or ponds and have the numbers peak when your fry are two weeks old

Furthermore, there is a need for a genetic map specifically for D. pulex because the current Daphnia assembly and genetic map are both derived from Daphnia arenata, an endemic species to Oregon rather than D. pulex that occurs in most of the temperate regions in North America

Daphnia Pulex Water Flea. Water Flea is a popular name for minute aquatic Crustaceans such as daphnia, cypris, and cyclops A water hardness of 40 to 48 mg/L is recommended for Daphnia pulex and 80 to 100 mg/L for D. magna (Section 2.4.9), conforming as well as possible with general use elsewhere . If hardness and other qualities of the dilution water are expected to affect the toxicity of a particular chemical that is to be tested, two or more tests could be run. Daphnia received the name water flea due to their jerky swimming motions. Daphnia pulex is very similar to D. magna, but is usually smaller. They are the most common species found across temperate North America. Daphnia lumholtzi is an invasive species originally from

We investigated three aspects of adaptation to variable environments in Daphnia pulex (Cladocera: Crustacea): (1) effects of temporal variation on the evolution of phenotypic plasticity ; (2) plasticity in sexual versus asexual lineages; (3) maintenance of genetic variation in variable environments. We performed a 72-day quasi-natural selection experiment comparing three patterns of variation. Daphnia pulex strain and its female- or male-producing conditions. The D. pulex WTN6 strain obtained from the Center for Genomics and Bioinformatics (Indiana University, IN, USA) was maintained in the National Institute for Basic Biology (Aichi, Japan) for more than two years. This strain was reared in dechlorinated freshwater, which was aerated and filtered through activated carbon for two weeks In total, 24 isolates (11 sexual D. pulex, 11 obligately asexual D. pulex, 1 D. pulex-arenata, and 1 Daphnia obtusa) were sequenced using Illumina paired-end short-read technology (library preparation and sequencing done by Beijing Genome Institute).

Using data from 83 isolates from a single population, the population genomics of the microcrustacean Daphnia pulex are described and compared to current knowledge for the only other well-studied invertebrate, Drosophila melanogaster . These two species are quite similar with respect to effective population sizes and mutation rates, although some features of recombination appear to be different. Daphnia pulex: Chaoborus-induced morphological alterations. In Chaoborus-exposed (n = 8) in comparison to unexposed D. pulex (n = 7), strongest shifts in morphology occur in the neckteeth region . This displacement is mainly due to a shift in dorsal direction. In the lateral dimension we observe a decrease in the head's thickness Habitat. The Daphnia pulex is a free-living aquatic organism which lives in freshwater environments. In fact, it is the most common water flea and can be found in almost every permanent, nutrient-rich fresh body of water surrounded by numerous other freshwater organisms and plants.The highest concentrations of Daphnia are found in the vegetation of most lakes and ponds The genus name Daphnia is derived via Latin from the Greek word, Daphne. According to mythology, Daphne was a nymph, who was saved from the unwelcome advances of Apollo by being transformed into a laurel tree. Daphnia are small freshwater crustaceans, commonly known as water fleas. They are called so due to the short, jerky flea-like movement.
