Gammarids

	Gammarids Gammaridae is a family of amphipods. In North America they are included among the folk taxonomic category of " scuds", and otherwise gammarids is usually used as a common name. They have a wide distribution, centered on Eurasia, and are euryhaline as a lineage, inhabiting fresh to marine waters. Systematics The Gammaridae were for a long time used as a "wastebin taxon", which included numerous genera of gammaridean amphipods that since then have been removed to their own families, such as the Anisogammaridae, Melitidae, Niphargidae. The following genera are currently listed in the family: '' Akerogammarus'' Derzhavin & Pjatakova, 1967 '' Albanogammarus'' Ruffo, 1995 '' Amathillina'' G. O. Sars, 1894 '' Axelboeckia'' Stebbing, 1899 '' Baku'' Karaman & Barnard, 1979 '' Cephalogammarus'' Karaman & Barnard, 1979 '' Chaetogammarus'' Martynov, 1924 '' Comatogammarus'' Stock, 1981 '' Condiciogammarus'' G.

	Gammarus Roeselii ''Gammarus roeseli'' is a species of freshwater amphipod native to Europe. Description ''Gammarus roeseli'' adult males reach a length of up to 22 mm; females are smaller than males. The species is distinct from many other common amphipods due to the spines on its fifth through seventh pereiopods. The color of ''G. roeseli'' individuals can vary from green to brown, gray, or yellow, and some have reddish markings on parts of their carapaces. Distribution ''Gammarus roeseli'' originated in the Balkan area of Europe, and appears to have populated the Pannonian Basin as a glacial refuge before expanding into central and western Europe 10,000 years ago. It is now widespread across continental Europe. Having been in France since at least the mid-1800s it is considered to be a well-established non-native species in central, northern, and western Europe. However, it continues to expand its distribution range, including into new river basins in Italy in the 2010s. Even within th ...

	Gammarus ''Gammarus'' is an amphipod crustacean genus in the family Gammaridae. It contains more than 200 described species, making it one of the most species-rich genera of crustaceans. Different species have different optimal conditions, particularly in terms of salinity, and different tolerances; ''Gammarus pulex'', for instance, is a purely freshwater species, while ''Gammarus locusta'' is estuarine, only living where the salinity is greater than 25 ‰. Species of ''Gammarus'' are the typical " scuds" of North America and range widely throughout the Holarctic. A considerable number are also found southwards into the Northern Hemisphere tropics, particularly in Southeast Asia. Species The following species are included: Four new species were found in 2018 on the Tibetan Plateau. Four more new species were described from the Chihuahuan Desert in 2021.
