Survival rates and mortality factors of adult bobcats in north-central Minnesota
1985 Journal of Wildlife Management (49): 292-296
Management of bobcat (Felis rufus) populations requires quantitive survival data. Some investigations requires quantitive survival data. Some investigations of bobcat populations dynamics use age structures of harvested animals to estimate survival rates (Crowe 1975, Bailey 1981, Blankenship and Swank 1981), but many have not adequately addressed the problems inherent in life table analyses (Caughley 1977, Gilbert 1981). Sex-, area-, and season-specific survival rates can be derived from radiotelemetry data (Trent and Rongstad 1974), as can the relative importance of legal harvest, poaching, and natural mortality. These estimates are often less biased than those based on carcass collection data or ear-tag returns and can be examined statistically (Heisey and Fuller 1985). This paper compares survival rates and mortality factors for radiocollared bobcats - 1.0 year old in two areas of north-central Minnesota during June 1971-August 1983.
