Biochemical Variation in the Black Bear
A total of 35 presumably distinct biochemical loci were analyzed in black bears (Ursus americanus) from Alaska, California, Maine, Montana, Tennessee, and Virginia by using starch-gel electrophoresis. Limited spatial subdivision of gene frequency was observed in Tennessee. Overall heterozygosity levels are lower in black bears than would generally be expected for mammalian species. Levels of in...
متن کاملLeucine Metabolism in the Black Bear
Metabolism of the essential amino acid leucine was studied in 3 black bears (Ursus americanus) in February while the bears were denning and not eating or drinking and in May while they were eating and drinking normally. (U-4C) leucine was injected as a bolus intravenously, and timed samples of venous blood were obtained over an 8-day period. Total activity in plasma gradually increased in Febru...
متن کاملAspiration pneumonia in an American black bear
Information regarding American black bear (Ursus americanus) mortality caused by disease is limited. Pneumonia is a common respiratory disease that affects many species of wildlife and can result in death. In February 2011, we investigated the death of a yearling male black bear and determined cause of death to be aspiration pneumonia. We found sections of lung were diffusely congested and edem...
متن کاملThe role of human outdoor recreation in shaping patterns of grizzly bear-black bear co-occurrence
Species' distributions are influenced by a combination of landscape variables and biotic interactions with other species, including people. Grizzly bears and black bears are sympatric, competing omnivores that also share habitats with human recreationists. By adapting models for multi-species occupancy analysis, we analyzed trail camera data from 192 trail camera locations in and around Jasper ...
متن کاملStatus and Management of Asiatic Black Bear and Himalayan Brown Bear in India
I review the current status of Asiatic black bear (Ursus thibetanus) and Himalayan brown bear (Ursus arctos) in India based on a questionnaire, interviews, and a literature survey. The Himalayan region and the hills of northeastern India probably support one of the largest populations of Asiatic black bear in Asia. Asiatic black bears live in forested mountain habitats (1,200-3,300 m) in the st...
