Wolves (Canis lupus) and moose (Alces americanus) have been studied since 1958 on 540-squarekilometer Isle Royale National Park, in Lake Superior. Wolves arrived there across the ice around 1949, and the population once increased to about 50, averaging about 25 annually (Mech 1966, Jordan et al. 1967, Vucetich and Peterson 2009). However, for vario...

At present, four organizations serve biologists in Alberta: The Alberta Chapter of the Wildlife Society (ACTWS), The Alberta Native Plants Council (ANPC), The Alberta Society of Professional Biologists (ASPB), and The Canadian Society of Environmental Biologists (CSEB). Only the ASPB is a professional regulatory organization, two of the others (CSE...

Winner of the 1984 Wildlife Publications Award from the Wildlife Society, the first edition of Wild Mammals of North America (published in 1982) offered zoologists, naturalists, wildlife specialists, and students detailed information about the biology, conservation status, and management of 57 mammalian species and species groups, with contribution...

WOLVES SHARE THEIR ENVIRONMENT with many animals besides those that they prey on, and the nature of the interactions between wolves and these other creatures varies considerably. Some of these sympatric animals are fellow canids such as foxes, coyotes, and jackals. Others are large carnivores such as bears and cougars. In addition, ravens, eagles,...

We summarized changes in the distribution and abundance of bison (Bison bison) in Wood Buffalo National Park from 1971 to 1998. Based on annual aerial counts, a significant decline in bison abundance has occurred from approximately 11,000 animals in 1971 to 2,300 animals in 1998. The decline occurred south of the Peace River, which includes the Pea...

Pursuit of Bison by Wolves was studied in conjunction with predator-prey studies in Wood Buffalo National Park. The average distance of chases was 4.9 km. This paper describes an unusual chase that was observed when a herd fled for 4.3 km before a calf was killed, then continued to run another 81.5 km within a 24-h period.

In the authors view the previous theoretical treatments of population viability have not been appropriate to gray wolves Canis lupus. The capability of existing nature reserves to support viable wolf populations appears related to size, shape and topograhy of the reserve; productivity, numbers, dispersion, and seasonal movement of prey; extent of p...

As the human impact on the earth leads to ever increasing environmental degradation, the restoration of dwindling populations of numerous plant and animal species is becoming ever more important. In this unique volume, the political, biological and experimental procedures affecting the restoration of natural populations are examined using a range o...

Considers the sometimes problematic relationship between traditional and scientific wildlife management knowledge and practices: environmental ethics, resource management systems, co-management arrangements and options, and the role of commissions in resource management.
