|Scientific Name:||Necturus beyeri|
|Species Authority:||Viosca, 1937|
Necturus punctatus (Brode, 1970)
|Taxonomic Notes:||Bart et al. (1995) determined that Necturus alabamensis and N. beyeri are distinct species and that the name N. alabamensis applies only to the waterdog in the upper Black Warrior River drainage (see Bart et al. (1997) for an account of the nomenclatural history of this and related species). Waterdogs included here in the N. beyeri complex evidently comprise multiple species (Guttman et al. 1990; Bart et al. 1997); further study is needed to resolve the
taxonomic status of the involved populations.
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)|
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
|Range Description:||This species can be found in Lower Coastal Plain from Texas eastward to the Mobile Bay drainage in Alabama, USA (Bart et al. 1997).|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||Populations in the core of the range are apparently secure.|
|Habitat and Ecology:||It can be found in spring-fed streams with sandy bottom. It is a bottom dweller. In Louisiana, it is closely associated with leaf-litter deposits in streams, and animals may burrow into bottom during warm season (Bart and Holzenthal 1985). Probably attaches eggs to objects in water.|
|Major Threat(s):||It is possibly threatened by stream siltation and pollution, but the important of this factor is unknown (Petranka 1998).|
|Conservation Actions:||Research on threats and population status are needed.|
