The development of structural defences, such as the fortification of shells or exoskeletons, is a widespread strategy to reduce predator attack efficiency. In unpredictable environments these defences may be more pronounced in the presence of a predator. The cladoceran Daphnia magna (Crustacea: Branchiopoda: Cladocera) has been shown to develop a bulky morphotype as an effective inducible morph...
Subfossil remains of insects and branchiopod crustaceans (Cladocera Notostraca) found in three late Pleistocene deposits the Novosibirsk region vicinity village Suzun have been described. The calibrated radiocarbon dates for these were 24,893–25,966 cal BP (Suzun-1), 20,379–20,699 (Suzun-2), 27,693–28,126 (Nizhny Suzun), which correspond to onset marine isotope stage 2 (MIS 2). insect assemblag...
BACKGROUND Fairy shrimps (Anostraca), tadpole shrimps (Notostraca), clam shrimps (Spinicaudata), algae (primarily filamentous blue-green algae [cyanobacteria]), and suspended organic particulates are dominant food web components of the seasonally inundated pans and playas of the western Mojave Desert in California. We examined the extent to which these branchiopods controlled algal abundance an...
The tadpole shrimp (Triops longicaudatus) is an aquatic crustacean that helps control pest populations. It inhabits freshwater ponds and pools and has been described as a living fossil. T. longicaudatus was officially declared an endangered species South Korea in 2005; however, through subsequent protection and conservation management, it was removed from the endangered species list in 2012. Th...
Northern California supports eight endemic species of large branchiopods (Crustacea: Anostraca, Notostraca, and Conchostraca), three of which are listed as endangered and one as threatened under the federal Endangered Species Act. Published information on the geographic distribution of these endemics from a biological perspective is scant. This study was initiated to gain a better understanding...
