Branchiopods.

The branchiopods consist of two major groups, the Anostracans and Cladocerans which are called fairy shrimp and water fleas respectively. Fairy shrimp live in freshwater pools and springs, and unlike other branchiopods, they lack a carapace and have stalked eyes. Their bodies are elongated, often with more than 20 trunk segments.To date, the only complete crustacean mitochondrial genome sequences available are those of two branchiopods: the brine shrimp Artemia franciscana (Branchiopoda, Anostraca) (Valverde et al. 1994) and the water flea Daphnia pulex (Branchiopoda, Cladocera) (Crease 1999). Thus, there is a dearth of mitochondrial sequence data available for ...Because of the vulnerability of branchiopods to predation, branchiopods are at risk whether precipitation increases or decreases with global climate change. The reduced precipitation (especially in summer) during the late '80's depleted the sediment cyst bank, reducing the potential size of future hatching populations by some unknown amount.Marine FossilScientific Name: Peniculauris bassi. This brachiopod fossil was found in the Kaibab Formation and is 270 million years old. It was a filter feeder that lived on or buried in the seafloor. Brachiopods look similar to mussels and clams, but are an entirely separate group of animals. The similarity in their appearance is the result of ...

It is the sister group to the other crustaceans. They are mostly small, freshwater animals that feed on plankton and detritus. However, many of the Cladocera are marine .

The extent to which dormancy in large freshwater branchiopods is controlled endogenously (diapause) or exogenously (quiescence) is not always clear. It is assumed that both processes occur even within the same brood. Based on the effectiveness of common diapause-deactivating processes such as desiccation, hibernation, and resting, it can be stated that diapause is not a general process ...

Pans suitable for large branchiopods were present in each region and all regions harbored most species. We believe that the underlying reason could be that variation in hydroperiod and associated environmental variables that matter for large branchiopods are still quite comparable among pans in the different regions. Even though some regions ...
