摘要

Conservation biologists are increasingly using novel techniques to sample free-ranging vertebrates. In particular, noninvasive approaches to sampling have become a major component of wildlife research (Garshelis 2006; MacKay et al. 2008).Originally these approaches were applied to “remote” tissue collection (e.g., feather, hair, feces) for DNA-based analyses, but they now include other techniques (e.g., stable isotopes, remote sensing, hormone analyses). Because noninvasive approaches generally imply that animals are sampled without capture or handling, they offer clear practical benefits. Noninvasive sampling often increases safety for both animal subjects and researchers, minimizes disturbance to animals, and, therefore, increases the accuracy of data while allowing larger sample sizes at a lower cost. For small populations, particularly of threatened and endangered species, minimizing risk to study animals is highly desirable and, in many cases, legally mandated.
