Cladocera - an overview | ScienceDirect Topics
Cladocerans are common inhabitants in a variety of inland waters. Attracted by their large swarms, naturalists described and depicted cladocerans as early as the 1600s. Extensive sampling from natural habitats has provided detailed information about distributions, as well as population and community structure.
Water flea | Daphnia, Cladocera & Zooplankton | Britannica
water flea, any member of the crustacean order Anomopoda (class Branchiopoda), a large group containing about 450 species distributed worldwide. Most forms are found in freshwater habitats, but a few occur in marine environments. The best known genus is Daphnia, ubiquitous in ponds and streams in Europe and North America.
Cladocerans - Encyclopedia of Arkansas
2020年7月1日 · Cladocerans are among the most successful invertebrates in freshwater ecosystems (including inland water bodies), whereas about eight species have also adapted to a living in marine environments, and several anostracans live in hypersaline lakes. Except for the genus Penilia, the marine species all belong to the family Podonidae.
Cladoceran Definition & Meaning - Merriam-Webster

Cladocera - an overview | ScienceDirect Topics
Cladocera are a diverse group of small crustaceans common in aquatic habitats, ranging from shallow temporary ponds to deep lakes and large rivers. Some groups (e.g., Podonidae) are widespread in the oceans.
Introduction to Cladocera - SpringerLink
2016年7月21日 · Cladocera is a group of planktonic, phythophilic, and benthic species. They form the plankton community as algae grazers (filtrators) and predators (raptors). They also live on the bottom sediments (as benthic species) or on the surface of …
Cladoceran Diversity, Distribution and Ecological Significance
2016年11月25日 · Cladocerans are an important group for biomonitoring, and the group has been used as indicator as well as test organisms for estimation of pesticide toxicity levels and other environmental pollutants. They are also one of the major natural food sources for the fishes, especially fry and fingerlings.
Cladocerans (‘‘water fleas’’) are primarily-freshwater small-sized (0.2–6 mm, and up to 18 mm in single case of Leptodora kindtii) branchiopod crustaceans, inhabiting pelagic, littoral, and benthic zones.
Sex Determination and Differentiation in Decapod and Cladoceran …
In this review, we summarize current knowledge on sex determination mechanisms and sex hormones (IAG and CFSH) in Malacostraca decapods and JH-driven sex determination pathways in the Branchiopod cladocerans from various studies, including recently developed OMICS approaches. Figure 1. Phylogeny of extant arthropods.
Global diversity of cladocerans (Cladocera; Crustacea) in freshwater ...
Cladocera is an ancient group of Palaeozoic origin. About 620 species are currently known, but we estimate that the real number of species is 2–4 times higher. A number of currently-recognised widespread species can be expected to harbour extensive cryptic diversity. Adamowicz, S. J., P. D. N. Hebert & M. C. Marinone, 2004.
