Predators and people: using human densities to interpret declines of large carnivores

摘要: The current extinction crisis is caused primarily by human impacts upon wild populations. Large carnivores are especially sensitive to activity; because their requirements often conflict with those of local people, predators have been actively persecuted in most regions the world. In this paper, impact people analysed relating carnivore extinctions past and projected population densities. There strong associations between high density loss populations from a region. Interspecific variation ability survive at densities probably reflects species' adapt human-modified habitats. However, regional temporal individual sensitivity more likely reflect activities than phenotypes carnivores. Local culture, government policy international trade all influence attitudes and, therefore, importance these factors may mean that risks for will continue increase, even though growth deccelerate during new millennium. This points an urgent need techniques resolve conflicts either or landscape level.
