Effects of winter road grooming on bison in Yellowstone National Park
Article Abstract:
Research describing the use of roads by bison during snow cover is presented. It is shown that winter grooming of roads does not impact greatly on bison ecology.

Emigration and density dependence in Yellowstone Bison
Article Abstract:
The density-dependent changes in population growth rates for bison during 1970 to 2000 were detected as numbers increased from to more than 3000 animals. Results concluded that pulses of climate-induced dispersal of bison from the central herd to the northern range during winter could create a source-sink dynamic that worsens the current controversy about management of bison.

Sampling and statistical analysis of snow-urine allantoin-creatinine ratios
Article Abstract:
Snow-urine samples were collected from different elk of different age and sexes in Yellowstone National Park over five winters. The ratio of allantoin-creatinine was tested, and trimmed means were used to find an average for cow elk, using both free-ranging and captive herds. The realistic sampling goal was set at 20 samples with two-week intervals over a winter. The ratio is a useful measure for assessing the nutritional status of elk during winter months.
