Branchiopods.

among branchiopods, we employed two approaches to taxon and gene sampling, presented new sequence data from three genes, incorpo-rated previously published sequence data from three additional genes, and utilized comprehensive techniques of phylogeny reconstruc-tion.

Branchiopods are unusual among crustaceans in that most species live in freshwater rather than marine habitats. The majority inhabits seasonally astatic (often called temporary, ephemeral, or vernal) pools, puddles, and streams that for most of the year remain dry. Thus, collecting adult branchiopods is more a matter of timing than of …Abstract Large branchiopods is a group of poorly understood crustaceans which is highly threatened by the impact of human activities. Currently, their protection is difficult due to large deficiencies in documentation of their places of occurrence and not well researched ecology. After rediscovery of Streptocephalus torvicornis in Poland by Cukier in 2019, we conducted a survey to identify the ...Branchiopod, any of the roughly 800 species of the class Branchiopoda (subphylum Crustacea, phylum Arthropoda). They are aquatic animals that include brine shrimp, fairy shrimp, tadpole shrimp, water fleas, and other small, chiefly freshwater forms. Branchiopods are generally regarded as primitive.

The crustacean group can be treated as a ...While Notostraca substitutions rate appears similar or lower in comparison to other branchiopods, a subset of genes shows a faster evolutionary pace, highlighting the difficulty of generalizing about genomic stasis versus dynamism. Moreover, we found that the variation of Triops cancriformis transposable elements content appeared linked to ...

Large branchiopods are adapted to these systems and survive drought phases as dor- mant eggs which can remain in the sediments of a dry wetland for many years (Wiggins et al. 1980, Rogers 2015a).

Large branchiopods have a worldwide distribution, occurring in some of the most remote places on earth such as Antarctica (Brendonck et al., 2008).

Branchiopods originally lived in all waters, before the existence of insects and fish. Once these predators appeared, the branchiopods were quickly eliminated from most aquatic environments. In the face of this evolutionary pressure, branchiopods diverged into two groups: small forms that mostly swim in the water column, (primarily …

An ...Data on the occurrence of large branchiopods in Poland in most of the cases date back to the turn of the 20th century (e.g. Ramułt 1939) and later reports have been very scarce (e.g. Zwolski 1956). Lack of recent data on distribution and conservation status of large branchiopods result in total lack of a conservation policy for this group.Typically, cladocerans have been used in these endeavors [15,19,20,26,27,28], and large branchiopods have only recently been used in these studies [21,22,25].
