摘要: Summary The removal of individuals through hunting can destabilize social structure, potentially affecting population dynamics. Although previous studies have shown that indirectly reduce juvenile survival increased sexually selected infanticide (SSI), very little is known about the spatiotemporal effects male on survival. Using detailed individual monitoring a hunted brown bears (Ursus arctos) in Sweden (1991–2011), we assessed effect cub survival. We modelled before, during and after mating season. We used three proxies to evaluate spatial temporal variation turnover; distance timing closest killed number males died around female's home range centre. Male decreased only season, as expected seasonal breeders with SSI. Cub within 1·5 years, it was lower when removed 1·5 instead 0·5 year earlier. did not detect an killed. Our results support hypothesis restructuring due recruitment suggest distribution deaths might be more important than overall die. As typically homogenously distributed across landscape, heterogeneity pressure may cause source–sink dynamics, areas high human-induced mortality.
