Productivity, mortality, and population trends of wolves in northeastern Minnesota Productivity, mortality, and population trends of wolves in northeastern Minnesota
Population parameters, mortality causes, and mechanisms of a population decline were studied in wolves (Canis lupus lycaon) from 1968 to 1976 in the Superior National Forest. The main method was aerial radio-tracking of 129 wolves and their packmates. Due to a decline in white-tailed deer (Odocoileus virginianus), the wolf population decreased during most of the study. Average annual...

Role of the wolf in a deer decline in the Superior National Forest Role of the wolf in a deer decline in the Superior National Forest
White-tailed deer (Odocoileus virginianus) declined in the Superior National Forest of Minnesota between 1968 and 1974. In a 3,000 sq km area of the poorest habitat, deer were decimated. Contributing factors were severe winters, deteriorating habitat, and wolves. Wolves killed older deer, but insufficient fawns were available to replace them.

Status, distribution, and movements of martens in northeastern Minnesota Status, distribution, and movements of martens in northeastern Minnesota
The decline of martens in Minnesota is reviewed and a recent increase documented. Adjacent and partially overlapping home ranges of 4.3 to 19.9 sq km were determined by telemetry for a female and three males. Habitat use is described. If current trapping and timber management practices persist, martens should continue to increase.

Wolf-pack buffer zones as prey reservoirs Wolf-pack buffer zones as prey reservoirs
In a declining herd, surviving deer inhabited overlapping edges of wolf-pack territories. There, wolves hunted little until desperate, in order to avoid fatal encounters with neighbors. Such encounters reduce wolf numbers and predation pressure and apparently allow surviving deer along territory edges to repopulate the area through dispersal of their prime, less vulnerable offspring into...
