Jollyville Plateau salamander

The Jollyville Plateau salamander (Eurycea tonkawae) is a species of salamander in the family Plethodontidae. It is also known as the Tonkawa Springs salamander.[2] It is endemic to Travis and Williamson counties, Texas, United States. This species is perrenibranchiate, retaining its gills throughout life.

Eurycea tonkawae is the sister taxon to E. naufragia and E. chisholmensis, two other endemic perrenibranchiate central Texas salamanders.

Its natural habitats are freshwater springs, spring runs, and wet caves of the Buttercup karst system. Cave dwelling E. tonkawae may represent a distinct species, however further work is needed to clarify their taxonomic status.

Conservation status

edit

Eurycea tonkawae is threatened by habitat loss and habitat degradation due to rapid urban growth. In August, 2013, this species was listed as threatened under the Endangered Species Act of 1973.[3]

Abundance and Distribution

edit

Eurycea tonkawae have a restricted in abundance in areas with an abundance of water such as the vicinity of wet caves, springs, and spring dominated surface flows.[4] They are known to inhabit aquatic habitats occupying areas under rocks, aquatic plants, and algae. Previous studies have shown highest abundance rates during rainfall seasons such as spring and summer.[5][6] Eurycea tonkawae occur in a clumped-like distribution, only being found in the Jolleyville Plateau and Bushy Creek areas in Texas counties.[6]
