Natural History of the Salamander, Aneides hardii

The authors document the ecology and behavior of Aneides hardii, a high‑elevation plethodontid found in spruce‑fir forests. Summer field studies emphasize microhabitat use—downed, heavily decomposed logs, loose bark, and talus—and seasonal retreat to subterranean or insulated sites in winter. Stomach analyses reveal a varied diet dominated by ants, with beetles, spiders, mollusks, and other arthropods also consumed. Collections included measurements, sexing, and notes on reproductive condition, including egg clusters found in logs. Captive observations describe feeding responses, growth with abundant food, and general foraging behavior. The report combines natural history notes, dietary data, and habitat-specific observations to characterize the species’ life habits.
