Natural History of the Salamander, Aneides hardii

This study offers a detailed portrait of a little‑known salamander that clings to the high‑elevation spruce‑fir forests of New Mexico’s Sacramento and Capitan Mountains. Over three rainy seasons the authors surveyed dozens of sites, measuring and sexing hundreds of individuals while noting the exact type of dead wood and talus where the creatures were found. Their observations reveal a striking preference for water‑logged Douglas fir logs in advanced decay, where the salamanders nest, feed and even lay eggs.

The researchers also tracked seasonal shifts, noting that the salamanders retreat to hidden subterranean spaces as snow and ice grip the forest floor. Stomach analyses show a opportunistic diet dominated by ants but including a wide range of small invertebrates. A handful of specimens were kept briefly in captivity, and all collected animals now reside in university and museum collections for future study.
