| Noninvasive sampling for carnivores | |
| 2012 Book Chapter | |
Now is an exciting time to study carnivore ecology via noninvasive sampling methods. Technological and methodological advances, and new techniques for data analysis, have contributed to a rapid increase in noninvasive carnivore studies. These studies complement and extend inferences from traditional sampling regarding individuals, populations, and communities. Today, researchers can estimate size and survival rate for a population, estimate historic and current rates of movement across fragmented landscapes, and measure carnivore stress loads without ever catching, handling, or even seeing a single animal. Noninvasive sampling is the gathering of data without capturing, handling, or otherwise physically restraining individual animals. The techniques usually imply that a target animal is not observed during data collection and, presumably, is unaffected by data collection. Although direct animal observations for behavioral studies and for distance sampling may also be considered noninvasive, we do not include these direct observation methods. Noninvasive data-collection methods include sign surveys, diet analyses, camera trapping, DNA extraction, and endocrine or disease monitoring from scats and hair. |
