Purine derivatives in snow-urine as a dietary index for free-ranging elk
Article Abstract:
Recent developments in the use of noninvasive techniques for assessing the nutritional status of free-ranging herbivores have included research on captive elk in which 116 snow-urine samples were assayed to determine concentrations of creatinine and the purine derivative allantoin. There was found to be a link between excretion of allantoin in urine and intake of digestible dry matter. This prompts the conclusion that indications regarding the nutritional status of wild ruminants may be obtained from urinary purine derivatives.

Brucellosis in Yellowstone National Park bison: quantitative serology and infection
Article Abstract:
Tissue and fluid samples were collected from 37 female bison from Yellowstone National Park to assess the link between antibodies to brucellosis and infection. The animals were killed as part of a management operation that focuses on those in the 2nd trimstre of pregnancy There was one seropositive calf and 27 seropositive adults. Twelve samples of 26 were seropositive for brucella abortus, and two samples had to be discarded due to contamination.

Reproduction and survival of Yellowstone bison
Article Abstract:
The survival, reproduction and birth rates of bison in Yellowstone National Park to study their overabundance in the park are examined. It is suggested that eradication of brucellosis by vaccination would result in an increase in their population, thus facilitating their movement outside the park.
