Pellet morphometry as a tool to distinguish age and sex in the mule deer
Abstract 10.1002/zoo.10119.abs By examining the morphometry (i.e., length, width, length-to-width ratio, and volume) of pellets in three different categories (adult males, adult females, and yearlings) mule deer (Odocoileus hemionus), we were able to distinguish via discriminant function and fuzzy clustering analyses the age and sex of these animals. To determine a priori the identity of […]
Predator and Heterospecific Stimuli Alter Behaviour in Cattle

Mountain biking is emerging as a popular form of outdoor recreation, yet virtually nothing is known about whether wildlife responds differently to mountain biking vs. more traditional forms of recreation, such […]
