They are the frequent targets of protection and management ...Large branchiopods are an ancient group of widespread taxa that have successfully colonised temporary aquatic ecosystems globally (Brendonck et al. 2008; Schernhammer et al. 2020). Their success has been ascribed to the numerous strategies they display that allow them to deal with variable and unpredictable habitat quality …Brachiopods are marine animals that secrete a shell consisting of two parts called valves. Their fossils are common in the Pennsylvanian and Permian limestones of eastern Kansas. Brachiopods have an extensive fossil record, first appearing in rocks dating back to the early part of the Cambrian Period, about 541 million years ago.

Insect diapause is a dynamic process consisting of several successive phases. The conception and naming of the phases is unsettled and, sometimes, ambiguous in the literature. In this paper, the ontogeny of diapause was reviewed and the most often used terms and the best substantiated phases were highlighted, explained and re-defined.Six different pH ranges were tested for the hatching rate of Triops cancriformis cysts. Cumulative hatching numbers approach to approximately 50% of cysts. The highest hatching rates, co-occurring with the shortest hatching times, were recorded in the neutral range. No hatching took place at pH values 9 and above. This corresponds with the most frequent habitats of this species, snowmelt pools ...Among the large branchiopods, the primary consumer Streptocephalus dichotomus (Anostraca) was more numerous than the predatory Triops granarius (Notostraca). However, while differing in ecological ...

Most large branchiopods inhabit endorheic waters that are of a temporary nature, atypical for the wet tropics but common in (semi)arid regions. Due to their ancient history and conserved morphology, they are often referred to as “living fossils.”. Adapted to cope with intermittent droughts, large branchiopods produce long lived resting eggs ...In many branchiopods the midgut is a simple tube with a pair of blind sacs, or diverticula. These diverticula may be simple extensions from the gut, or they may be complexly branched as in the notostracans and the spinicaudates. Some anomopods of the family Chydoridae have coiled midguts and may also have a single posterior diverticulum.

For example, 8 fairy shrimp species were identified from the Save Valley Conservancy in Zimbabwe (Nhiwatiwa et al., 2014), and 7 species of large branchiopods including 3 anostracans were detected in Wielkopolska, Poland (Goldyn et al., 2012). Here, we detected three species belonging to three different families of fairy shrimp at a small ...The Western Cape, one of South Africa's better performing provinces in terms of educational outcomes, has a relatively well-run education bureaucracy when compared not only within South Africa but also with other middle-income country education systems.Vernal pool branchiopods in California are passively dispersed ephemeral wetlands specialists. They are the frequent targets of protection and management due to their important role in the vernal pool community. So far, genomic resources for branchiopods has been limited. Like many crustaceans, branchiopod lineages are ancient.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 today are relatively diverse, yet many of their traits have not changed appreciably for thousands, perhaps millions of years.” 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.

Large branchiopods inhabit diverse continental habitats worldwide. Their feeding ecology, nevertheless, remains largely unknown. The few functional morphology studies that have been conducted have mostly focused on adults or larvae, seldom have the two been compared collectively.
