Lepidurus Articus
''Lepidurus'' is a genus of small crustaceans in the order Notostraca (tadpole shrimp). It is the larger of the two extant genera of the tadpole shrimps, the other being ''Triops''. They are commonly found in vernal pools and survive dry periods with the help of long lasting resting eggs. The genus contains the following species: *''Lepidurus apus'' (Linnaeus, 1758) *''Lepidurus arcticus'' (Pallas, 1793) *''Lepidurus batesoni'' Longhurst, 1955 *''Lepidurus bilobatus'' Packard, 1883 *''Lepidurus couesii'' Packard, 1875 *''Lepidurus cryptus'' D.

Lepidurus Arcticus
Arctic tadpole shrimp ''Lepidurus arcticus'' is a species of tadpole shrimp which inhabits ephemeral pools, ponds or permanent freshwater lakes of Finland, Norway, Sweden, Svalbard, Greenland, Iceland, Russia and the Kuril Islands.Schlager, Neil, et al. Grzimek's Animal Life Encyclopedia. Gale. 2004 . Unlike other species of tadpole shrimp, ''Lepidurus arcticus'' is known to coexist with fish, such as Arctic char, brown trout and European whitefish. Furthermore, they exist in water temperatures much colder () than the other species of its order. About 14 °C seems to be the upper thermal threshold for where in which waters it can live. It is a common predator of ''Daphnia pulex ''Daphnia pulex'' is the most common species of water flea. It has a cosmopolitan distribution: the species is found throughout the Americas, Europe, and Australia. It is a model species, and was the first crustacean to have its genome sequenced. ...''.

Branchiopoda Genera
Branchiopoda, from Ancient Greek βράγχια (''bránkhia''), meaning "gill", and πούς (''poús''), meaning "foot", is a class of crustaceans. It comprises fairy shrimp, clam shrimp, Diplostraca (or Cladocera), Notostraca, the Devonian ''Lepidocaris'' and possibly the Cambrian '' Rehbachiella''. They are mostly small, freshwater animals that feed on plankton and detritus. Description Members of the Branchiopoda are unified by the presence of gills on many of the animals' appendages, including some of the mouthparts. This is also responsible for the name of the group (from the , gills, akin to , windpipe; , foot). They generally possess compound eyes and a carapace, which may be a shell of two valves enclosing the trunk (as in most Cladocera), broad and shallow (as in the Notostraca), or entirely absent (as in the Anostraca). In the groups where the carapace prevents the use of the trunk limbs for swimming (Cladocera and clam shrimp), the antennae are used for locomotio ...

Lepidurus Packardi
''Lepidurus packardi'', the vernal pool tadpole shrimp, is a small, rare species of tadpole shrimp (Notostraca) found in temporary ponds of the western United States. Distribution The freshwater crustacean is endemic to California, where it lives in the endangered vernal pool type of habitat, and other freshwater aquatic habitats including ponds, reservoirs, ditches, road ruts, and other natural and artificial temporary water bodies. The animal is found in several regions of California, including the Central Coast, Sacramento Valley, San Joaquin Valley, and southern Sierra Nevada foothills. The southeastern Sacramento Valley contains about 15% of the remaining vernal pool grassland habitat in the state, and it has about 35% of the known occurrences of ''L. packardi''. 28% of all occurrences are in Sacramento County, California. Other areas with occurrences include the Don Edwards San Francisco Bay National Wildlife Refuge, several preserves in Tehama County, and the vicini ...

He was a professor at the University of California, Berkeley from 1912 to 1938. He was a genetics researcher who studied animal behavior, heredity, and evolution. Over the course of his career he migrated from studying animals to humans, taking the behaviors and traits learned in the former and looking for them in the latter. Education and career Holmes attended Chaffey College in Ontario, California, and obtained his Bachelor of Science (1893) and Master of Science (1895) from the University of California, Berkeley. His biological research at Berkeley earned him a fellowship to the University of Chicago in 1895, where he received his Ph.D in 1897. After teaching at San Diego High School for the academic year 1897–1898, between 1898 and 1906 he was an instructor of zo ...
