How Hot is Too Hot? Live-Trapped Gray Wolf Rectal Temperatures and 1-year Survival
The ability of physically restrained and anesthetized wolves to thermoregulate is lessened and could lead to reduced survival, yet no information is available about this subject. Therefore, we analyzed rectal temperatures related to survival 1 year post-capture from 173 adult (non-pup) gray wolves (...
