Factors that affect the repeatability of personality in yellow-bellied marmots, <i>Marmota flaviventris</i>
Abstract
Animal personality is becoming increasingly relevant behavioral ecology because of its potential impact on reproductive success. Measuring personality however can be difficult because many factors, such as microhabitat variation and habituation, affect how an animal responds to a given test. Using novel object tests to measure exploration and a flight initiation distance test to measure boldness, we quantified which variables significantly affect individual responses in a population of yellow-bellied marmots near Rocky Mountain Biological Laboratory. We found that alert distance and distance to burrow affect boldness tests. Furthermore, although we could not demonstrate habituation over time to the tests, other significant factors, such as age class and location in the valley suggests that the marmots may already be habituated to humans.
