Creator:: Delie, Jackie S.
Abstract:: The social sciences are increasingly used in conservation to describe interactions and relationships between humans, wildlife, and ecosystems. Scientists and policy-makers have concluded that promoting human tolerance for wildlife is critical to the success of conservation efforts. Yet, the concept of tolerance is relatively new in the context of human-wildlife...

Creator:: Mortenson, Jack A.
Abstract:: The causes of natural mortality and disease in free ranging black bears, Ursus americanus, in California, Oregon, and Washington are poorly known. Life history components, such as scavenging and overlapping habitat with many species of carnivores, potentially expose bears to a wide range of infectious disease agents. To date, no...

Creator:: Tomas, Walfrido Moraes
Abstract:: Riparian zones are critical habitats for management because of their importance for both cattle production and wildlife, and a high potential for resource conflicts. Riparian management should address habitat and microhabitat features that sustain both livestock production and wildlife diversity. I conducted a study to determine how small mammal distributions...

Creator:: Halstead, Katherine E.
Abstract:: The combined effects of habitat loss, degradation, and fragmentation pose a serious threat to Earth's biodiversity, imperiling even relatively common species. 'Habitat' is necessarily a species-specific concept, and investigations of bird diversity relationships and subsequent efforts to prioritize conservation areas, are challenged by the difficulty of estimating complex habitat gradients...
