Captive breeding, husbandry, release, and translocation of sciurids

Captive breeding and release programs have been instrumental in preventing the extinction of some wildlife species, but these programs have been less successful for other species. Evaluating initial guidelines for procedures to start a captive breeding and release program for a particular species is an important first step in the process of initiating such a program. The Mohave ground squirrel (Xe

Multi-scale relationships in thermal limits within and between two cold-water frog species uncover different trends in physiological vulnerability

1. Critical thermal limits represent an important component of an organism's capacity to cope with future temperature changes. Understanding the drivers of variation in these traits may uncover patterns in physiological vulnerability to climate change. Local temperature extremes have emerged as a major driver of thermal limits, although their effects can be mediated by the exploitation of fine-sca
