MARIN-SANCHEZ, Ariadna I.; BRIONES-SALAS, Miguel; LOPEZ-WILCHIS, Ricardo  e  SERVIN, Jorge. Coyote (Canis latrans) home range in a temperate forest from the Sierra Madre, Oaxaca, Mexico. Rev. Mex. Biodiv. [online]. 2015, vol.86, n.2, pp.440-447. ISSN 2007-8706.  https://doi.org/10.1016/j.rmb.2015.04.013.

The size of the coyote's (Canis latrans ) home range was estimated in a temperate forest in Sierra Madre, Oaxaca, Mexico. The periods of reproduction, gestation, breeding and pups independence and rain and dry seasons are compared. A collar with activity sensor was placed in 4 coyotes and monthly readings were registered in cycles of 24 h. To delimit the home range area minimum convex polygons at 95% in digital maps were employed. The average size of the home range for all coyotes was 3.45 km2 with a bigger size in the period of independence (4.74 km2), followed by gestation (4.58 km2), reproduction (2.44 km2) and breeding (2.04 km2); but significant differences between periods were not found per coyote, nor when doing a comparison between them. The average value in the home range for the seasons was 6.52 km2, higher for the dry one with 6.69 km2. The size of the female's home range was higher during the dry season, while for the young male was higher during the rainy season. It was concluded that there are significant differences among coyotes due to sex and age.
