A comparison of coyote ecology after 25 years: 1978 versus 2003

摘要: Most ecological studies of coyotes are short duration and generally never repeated, thus the opportunity to compare changes in coyote (Canis latrans Say, 1823) ecology over time is rare. We compared home ranges, activity patterns, age, diet at Welder Wildlife Refuge south Texas between 1978–1979 2003–2004 (25 years later). The Minta index overlap 1978 2003 ranges was 51.7 ± 7.0 (n = 7), much greater than value based on randomized tests (28.7 8.6), indicating similar spatial patterns periods. 12.3 6.2 7) for core areas, whereas 4.0 3.0. Although overall diets were 2003, we detected some differences prey species consumed. Activity two study periods, with peaks movement occurring around sunrise sunset. There no difference mean age populations (P ...
