Enumerating megapopulations of wild bears with an ingested biomarker
Article Abstract:
Black bear population estimates are generally derived from a mark-recapture approach, although this can yield unrepresentative results because it is limited to smaller study areas. A study of black bear population size in northern Minnesota and the Upper Peninsula of Michigan, used bait containing tetracycline as a biomarker. Population estimates were made using the Lincoln-Petersen approach, and a model was used to asses relative vulnerabilities to hunting of marked and unmarked bears. The bears could be marked over a wide area and the technique could be applied to other bear species.

Home ranges of sloth bears in Nepal: implications for conservation
Article Abstract:
Some 18 sloth bears from the Royal Chitwan National Park in Nepal were tracked for about three years to investigate the extent of their home ranges. The 1990-1993 study found that even though eight males made seasonal home range shifts to the sal forest, the two smallest males and most females declined to do so. Generally, it showed that sloth bears have smaller home ranges than other ursids and that they sourced their food supply during the dry season from the alluvium.

Annual home ranges and spacing patterns of capercaillie in Central Europe
Article Abstract:
The habitation requirements and home range use of the capercaillie were investigated. Specifically, 40 capercaillie in the Bavarian Alps, Germany, were radio-tagged between 1988 and 1992 to study the size, vegetation and diameter of their home range. The results, which indicated long-term use of the same home range, showed the inverse relation between home range size and the availability of billberry and forest succession.
