| Popis: | Coyote (Canis latrans Say, 1823) is a recent immigrant into eastern United States and little is known about the species’ space use and movement in the region. We compared space use and movement of radio-collared coyotes among biological seasons. We captured and collared 30 coyotes from February through May 2011 and collected 85 386 GPS locations through October 2012 at Fort Bragg Military Installation. We defined four biological seasons according to coyote life history: breeding (December–February), gestation (March–May), pup-rearing (June–August), and dispersal (September–November). Out of 27 radio-collared individuals, we identified 10 as transient and 11 as resident based on home-range size and variability across seasons; 6 switched their status and were classified as intermediate. We observed low variability of core-area size across seasons for resident males and females, whereas we documented high variability for transient males. Movement rate of resident coyotes during spring (449.75 m/h) was greater than summer (295.33 m/h), whereas movement rates did not differ between any other seasons. For transient coyotes, movement rate during summer (283 m/h) was less than fall (374.73 m/h), spring (479.85 m/h), and winter (488.5 m/h). Some coyotes adjusted their residency status seasonally and other individuals dispersed large distances (>200 km). |
