Californian Anostraca: Distribution, Habitat, and Status

Weak phylogeographic structure in the endemic western North American fairy shrimp Branchinecta lynchi (Eng, Belk and Erickson 1990)

“…Branchinecta fairy shrimp predominately inhabit seasonal wetlands, which are currently being lost in California at an extremely high rate due to development and degradation by human activities (Belk 1998). B. lynchi (Eng et al 1990) has the widest distribution for any of the CA endemic Branchinecta, found in the Santa Rosa Plateau, Santa Barbara County, Ventura County, the Coast Ranges of Monterey County, throughout the great Central Valley, and in the Agate Desert of southwestern Oregon (Fig. 1).…”

“…1). This species was only recently described by Eng et al (1990). B. lynchi inhabits a variety of vernal pool habitats, from clear, small to moderately sized vernal pools and swales to larger turbid vernal playas (Eriksen and Belk 1999).…”

Hatching response to temperature along a latitudinal gradient by the fairy shrimp Branchinecta lindahli (Crustacea; Branchiopoda; Anostraca) in culture conditions

“…The fairy shrimp Branchinecta lindahli Packard, 1883 is a widespread North American species known from Canada (Alberta), USA (Arizona, California, Colorado, Iowa, Kansas, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oklahoma, Oregon, Washington, Wyoming), and Mexico (Baja California, Baja California Sur) (Lynch, 1964;Hartland-Rowe, 1965;Belk, 1975Belk, , 1977aBelk, , 1977bBelk, , 1983Belk and Brtek, 1995;Eng et al, 1990;Eriksen and Belk, 1999;Maeda-Martinez et al, 2002). This broadly distributed species is recorded from a range of endorheic temporary wetland habitat types from dryland regions, including: alkaline vernal pools, prairie potholes, and slightly saline pools and playas (Hartland-Rowe, 1965;Horne, 1967Horne, , 1971Belk, 1977bBelk, , 1983Eng et al, 1990;Gonzales et al, 1996;Eriksen and Belk, 1999;Maeda-Martinez et al, 2002).…”

“…Horne (1967Horne ( , 1971 reported that B. lindahli is remarkably tolerant of a wide range of dissolved salts types and concentrations. This species is known from turbid and clear water habitats (Eng et al, 1990). It is commonly encountered in artificial habitats, such as roadside ditches and railroad bed toe drains (and has been recorded co-occurring in the same habitats with fifteen other fairy shrimp species in five other genera) and the adults typically swim in temporary wetlands that hold water November to April (Lynch, 1964;Hartland-Rowe, 1965;Belk, 1977bBelk, , 1983Eng et al, 1990;Eriksen and Belk, 1999;Maeda-Martinez et al, 2002).…”
