Crowe, D.M.
A model for exploited bobcat populations in Wyoming
1975 Journal of Wildlife Management (39): 408-415
Rising fur prices and concurrent increases in aesthetic and sporting values suggest a need for more intensive management of bobcats (_Lynx rufus_). One hundred sixty-one animals collected from 1970 through 1973 were used to provide information on reproduction, mortality, and age-structure. An analysis of 81 reproductive tracts indicated that all females were sexually active during the breeding season. The peak period of breeding was in March. The average litter size was 2.79 and the majority of births were within two weeks of 1 June. Age-structure and harvest data supplied a basis from which to estimate annual mortality rates. From information on reproduction and mortality a model describing annual population fluctuation was constructed. Applications of this concept of the mechanics of bobcat populations are discussed with regard to sustained optimum yields and predation control.
