Hunting promotes sexual conflict in brown bears
The removal of individuals through hunting can destabilize social structure, potentially affecting population dynamics. Although previous studies have shown that hunting can indirectly reduce juvenile survival through increased sexually selected infanticide (SSI), very little is known about the spatiotemporal effects of male hunting on juvenile survival. Using detailed individual monitoring of ...
متن کاملCan hunting data be used to estimate unbiased population parameters? A case study on brown bears
Quantifying temporal changes in harvested populations is critical for applied and fundamental research. Unbiased data are required to detect true changes in phenotypic distribution or population size. Because of the difficulty of collecting detailed individual data from wild populations, data from hunting records are often used. Hunting records, however, may not represent a random sample of a p...
متن کاملTelomere length and body temperature—independent determinants of mammalian longevity?
WHY DO SPECIES DIFFER IN LIFESPAN AND WHAT ARE THE DETERMINANTS OF THEIR LONGEVITY? Understanding the main factors that determine variation in species longevity may provide a clue into the leading mechanisms of aging and—what is even more important—outline the key targets for longevity-promoting interventions. Comparative studies on longevity in mammals revealed numerous variables that correlat...
متن کاملFactors Affecting Local People’s Fear of Brown Bears (Ursus Arctos) in Protected Areas of Alborz Province
Wildlife management and conservation is challenged by public perceptions and fear of carnivores in communities living in close proximity to wild habitats, where large carnivores occur. Fear of carnivores influences peoplechr('39')s attitudes towards wild animals, further exacerbating the problems associated with effective conservation and management of wildlife. Here, we aimed to investigate th...
متن کاملThe relative importance of direct and indirect effects of hunting mortality on the population dynamics of brown bears
There is increasing evidence of indirect effects of hunting on populations. In species with sexually selected infanticide (SSI), hunting may decrease juvenile survival by increasing male turnover. We aimed to evaluate the relative importance of direct and indirect effects of hunting via SSI on the population dynamics of the Scandinavian brown bear (Ursus arctos). We performed prospective and re...
