Demography of decline of the Red Wine Mountains caribou herd
Article Abstract:
Little is understood about the causes of the decline in woodland caribou numbers across North America, although there may be relationships to moose density and predation by gray wolves. A new study compares the population characteristics of woodland caribou of Labrador's Red Wine Mountains Herd before and during a population decline. The study shows that gray wolves are the most frequent cause of death of caribou under one-year-old and they may mediate the population dynamics of woodland caribou when associated with periods of high moose densities.

Refining the equation for interpreting prey occurrence in gray wolf scats
Article Abstract:
A new equation, (Y = 0. 439 + 0.008X), is used to estimate the occurrence of prey in gray wolf scats. Three gray wolves are fed with the carcasses of mule deer (Odocoileus hemionus), moose (Alces alces) and elk (Cervus elaphus) to define the equation for interpreting prey occurrence. With an increase in body mass of the prey (X), the mass (kg) of prey per collectable scat (Y) increases. The equation covers prey sizes from snowshoe hare (Lepus americanus) to adult moose and can be used in different field conditions.

Landscape use and movements of wolves in relation to livestock in a wildland-agriculture matrix
Article Abstract:
A three-year study is conducted to investigate the activity patterns, movements, habitat use, visitation of livestock pastures by wolves, and the occurrence of depredation events in an agricultural-wildland matrix in northwestern Minnesota, USA. Space use of wolves showed that while they visited livestock pastures during the 24-hour tracking sessions, they apparently were passing through these pastures with cattle and not preying on livestock.
