Plasma levels of ursodeoxycholic acid in black bears, Ursus americanus: seasonal changes.
To date, no other studies have examined the seasonal changes in circulating levels of various bile acids in the plasma of wild North American black bears, Ursus americanus. Using gas chromatography, bile acid concentrations were measured in plasma samples obtained during either early or late hibernation, and during summer active periods. Thus, specific compositional changes from individual anim...
متن کاملThe Shared Preference Niche of Sympatric Asiatic Black Bears and Sun Bears in a Tropical Forest Mosaic
BACKGROUND Ecologically similar species often coexist by partitioning use of habitats or resources. Such partitioning can occur through divergent or shared niches. We investigated overlap in habitat use and spatial co-occurrence by sympatric Asiatic black bears and sun bears in three habitats in Thailand, and thereby assessed which niche model best accounts for their coexistence. METHODS/PRIN...
متن کاملStatus of Asiatic black bears in protected areas of Nepal and the effects of political turmoil
We conducted informal interviews with villagers and park and buffer zone personnel in protected areas of Nepal presumed to contain Asiatic black bear (Ursus thibetanus) during 19 September–10 November 2005. Based on these interviews, we assessed the presence and persistence of this species in Nepal. We conducted interviews in Shey Phoksundo National Park, Langtang National Park, Shivapuri Natio...
متن کاملEcological Network Planning for the Asiatic black bears in Fuji-Tanzawa region, Japan
The Japanese National Biodiversity Strategy 2010 calls for the creation of ecological networks as a biodiversity conservation policy. This study proposed a plan of ecological networks to conserve two threatened local populations of Asiatic black bear (Ursus thibetanus japonicus) in Fuji and Tanzawa region in Japan with the support of GIS technologies. Using the predicted habitat patches of bear...
متن کاملFactors Influencing Home-range Size of Female Florida Black Bears
The manner in which space is utilized by animals is influenced by several factors, including habitat quality and the distribution and abundance of resources. We used 4 years (2000–2003) of radiotelemetry data to investigate the space-use pattern of female Florida black bears (Ursus americanus floridanus) in the Ocala National Forest and an adjacent residential community of Lynne, north-central ...
