Latest Branchiopoda Stories
New research on a number of Canadian lakes show that historical acid deposits as a result of industry have greatly reduced calcium levels in the water - dramatically impacting populations of calcium-rich plankton such as Daphnia water fleas that dominate these ecosystems.

New research has now investigated the origin of tadpole shrimps, a group commonly regarded as 'living fossils' which includes the familiar Triops. The research reveals that living species of tadpole shrimp are much younger than the fossils they so much resemble, calling into question the term 'living fossil'.
Daphnia is a genus of small, planktonic crustaceans, commonly called 'water fleas' because of their jumpy swimming style and their size (between 0.2 and 5 mm).
Anatomically complex brains evolved earlier than previously thought and have changed little over the course of time, according to a new study by University of Arizona neurobiologist Nicholas Strausfeld.
Tadpole shrimp are pests of rice production systems in California and have recently been found impacting Missouri and Arkansas rice fields.
Environmental change is the selective force that preserves adaptive traits in organisms and is a primary driver of evolution.
When battling a deadly parasite epidemic, less resistance can sometimes be better than more, a new study suggests.
When it comes to battling a deadly parasite epidemic, it may be better not to fight it. A new study of freshwater zooplankton suggests less is more when it comes to evolving against a parasitic epidemic.

The vernal pool fairy shrimp (Branchinecta lynchi) is a species of crustacean that can be found in freshwater vernal pools in the states of Oregon and California in the United States. In Oregon, it has been found in the Agate Desert and on the Upper and Lower Table Rocks, while in California this species can be found in thirty-two locations. It resides in vernal, or temporary, pools that hold a temperature between 43 °F and 68 °F. The vernal pool fairy shrimp varies in size between 0.43...
Scientific name: Streptocephalus woottoni Common Names: Riverside Fairy Shrimp Status: Listed as endangered on the IUCN Red List on August 1, 1996 Geography: Mexico, United States Conservation Information: This species is found only in five locations in southern California and two location in northern Baja California. Some known population occurrences have been extirpated. It is threatened by habitat loss, degradation and fragmentation. In December 2012, the US Fish and Wildlife...
Scientific name: Branchinecta conservatio Common Names: Conservancy Fairy Shrimp Status: Listed as endangered on the IUCN Red List on August 1, 1996 Geography: Native to the United States (Southern California) Conservation Information: The historical distribution of this species is unknown. However, places where the species is now known to occur (vernal pools in southern California) once held more continuous and larger populations than there are today. The species is known from...
The vernal pool tadpole shrimp (Lepidurus packardi) is a species of shrimp that can be found in California and southern areas of Oregon. Its range includes the Agate Desert in Oregon and many areas in California including the Central Coast, the San Joaquin and Sacramento Valleys, and the southern foothills of the Sierra Nevada. This species prefers to reside in vernal pools, which are now rare, but it can be found in other freshwater habitats including ditches, reservoirs, and ponds. The...
