Branchiopods.

The large branchiopods are the enigmatic flagship invertebrates of temporary wetlands worldwide (Brendonck et al., 2008). They are specialists of lentic environments that incorporate a dry phase, although in some cases they do occur in fishless semi-permanent waterbodies (Ferreira et al., 2011). Their adaptations to ephemeral waterbodies have led …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 ...Location of the sites sampled for large branchiopods in the Eastern Cape Karoo region of South Africa (a), including a zoomed-in perspective of the 22 sites within the focal study area (b).3 Feature - a single instance of listed large branchiopod habitat, such as a vernal pool, swale, or other inundated depression.

1. Introduction. In most metazoans, the mitochondrial genome DNA is a typically closed-circular molecule (14-18 kb in length) and autonomously replicated and transcribed (Boore, 1999, Nakao et al., 2002).Although the gene rearrangements and deletions have been observed in several species (Liu and Cui, 2009, Shen et al., 2007), the mitochondrial genome generally encodes 37 genes: 13 protein ...

In this study, we examine, identify, and discuss fossil remains of large branchiopod crustaceans collected from six sites across the Beringian region (north-eastern Asia and north-western North America). Eggs and mandibles from Anostraca andSep 1, 2020 · As large branchiopods are highly threatened and can serve as umbrella species for these habitats, we argue that dedicated conservation measures (e.g. offering compensation measures for landowners with temporary pools in fields or grasslands the Austrian agricultural policy) should be directed towards this iconic species group.

The climate of the Black Rock Desert playa in particular is semi-arid with mean annual precipitation of about 6.75 in. Maximum summer temperatures can exceed 95 degrees Fahrenheit, and minimum winter temperatures are often below freezing. Evenings can be below 45 degrees in the summer and over 110 degrees in the day.

In Mexico, and Arizona, as in many parts of the world, multispecies assemblages of large branchiopods are a common phenomenon.Different branchiopods have different ecological preferences, and with large taphocoenosis data sets it is possible to determine aspects of the palaeoenvironment. Many cladoceran remains have been accurately identified to species [15,16,17,18].

They are covered by two valves, or shells; one valve covers the dorsal, or top, side; the other covers the ventral, or bottom, side. The valves, of unequal size, are bilaterally symmetrical; i.e.,Order Anostraca (fairy shrimp of large branchiopods) is a primitive crustacean group, retaining ancient forms and ecology. The Holarctic family Chirocephalidae originated over 100 million years ago; it is a very long-lived freshwater taxon that has survived from the Mesozoic to the present. Thus, using this taxon as an indicator, we verified how the geographical distribution of freshwaters ...We asked whether two branchiopods, Triops longicaudatus and Streptocephalus mackini, use multiple spectral channels to regulate their position in the water column. At the lowest intensities that elicited photonegative behavior, both species had broad spectral bandwidths, suggesting they use multiple spectral photoreceptor …

Large branchiopods are known for 'bet hedging' strategies, whereby egg banks do not necessarily hatch out on every inundation and thus could be absent from the surface water during a given sampling event, but remain in the substrate as eggs (Brendonck and De Meester 2003, Schwentner and Richter 2015, Rogers 2015a, b).
