摘要: Mortality and survival of white-tailed deer Odocoileus virginianus fawns (N = 29) were studied from birth to one year age during 1991–95 on Mount Desert Island (MDI), Maine, where hunting is prohibited, coyotes Canis latrans have become recently established, protected U.S. National Park lands are interspersed with private property. The rate predator-caused mortality was 0.52, coyote predation 8) accounting for at least 47% mortalities all causes 17). drowning 0.24 3), vehicles 0.14 3). For radio-collared as neonates, 10 14 occurred the first two months life. Annual fawn 0.26. Survival six 0.65 four (two predation, drowning) observed this interval. A subgroup 11) captured near a residential area along periphery territory had higher (S 0.67) than did other areas 18, S 0.00). Recruitment lower that in populations northeastern United States. Low recruitment associated sources humans appears be limiting some segments insular landscape.
