Evaluation of age determination techniques for gray wolves
Article Abstract:
A full understanding of gray wolf population dynamics requires an accurate method to determine age. The cementum-annulus count is an accurate technique for estimating age in herbivores, but its use in carnivores is difficult because of the variability of cementum patterns in wolves. The accuracy of tooth wear, cranial suture fusion, cementum annuli and closure of the canine pulp cavity are compared as methods for determining the age of grew wolves. It is concluded that cementum-annulus is the most accurate method for estimating the age of adult gray wolves.

Selection of northern Yellowstone elk by gray wolves and hunters
Article Abstract:
Selection of northern Yellowstone elk (Cervus elaphus) by hunters in the Gardiner Late Hunt and northern Yellowstone wolves (Canis lupus) with regard to sex, age, and impacts to recruitment is compared. The effects of hunting and wolf predation on reproductive female elk are assessed by constructing a life table and calculating reproductive values for females in the northern Yellowstone herd.

Effects of recreation and hunting on flushing distance of Capercaillie
Article Abstract:
The effects of recreation and hunting on flushing distance of capercaillie are studied. Results conclude that the degree of visibility between capercaillie and recreationists should be reduced by planting or preserving conifer trees as well as a sufficient area of undisturbed habitat and closing trials should be assured.
