Cochran's False Brook Salamander

Cochran's false brook salamander (Pseudoeurycea cochranae) is a small, slender plethodontid salamander endemic to the pine-oak and cloud forests of the eastern Sierra Madre Occidental and adjacent ranges of Mexico. Like all members of the family Plethodontidae, it is lungless — respiration occurs entirely through moist skin and mucous membranes of the mouth, constraining the species to damp microhabitats such as mossy rock faces, rotting logs, and the leaf litter layer in humid montane forest. The species is direct-developing, laying small clutches of eggs in moist terrestrial sites from which miniature fully formed salamanders emerge, bypassing the aquatic larval stage characteristic of most other amphibian orders. Pseudoeurycea cochranae is a nocturnal forager, preying on small invertebrates including collembolans, mites, and small beetles encountered during nightly activity in its humid forest microhabitat. The species is classified as Vulnerable by the IUCN owing to its limited distribution, continuing deforestation driven by logging, agricultural conversion, and human settlement in its montane range, and susceptibility to climate-driven shifts in the moisture regime of cloud forest habitats. The genus Pseudoeurycea is largely endemic to Mexico and comprises several dozen species, many of which are similarly threatened. Like several congeners, P. cochranae is named in honour of Doris Mable Cochran. Population monitoring in its restricted range is an ongoing conservation priority.
