Habitat Selection at Multiple Scales
It is outlined how reward/risk ratios can be used to assess the fitness implications of habitat selection across scales, and by linking habitat selection to fitness as a function of scale, use-of-habitat assessments can be more effective. Expand
Population genetic structure and the effect of founder events on the genetic variability of moose, Alces alces, in Canada
Comparisons of allele frequencies for moose from 11 regions of the country suggested that there are at least seven genetically distinct populations in North America, namely Alberta, eastern Ontario, New Brunswick, Cape Breton, Labrador, western Newfoundland, and the Avalon Peninsula of Newfoundland.

Responses of woodland caribou (Rangifer tarandus caribou) to clear-cutting in east-central Newfoundland
Movements, sex and age structure, and habitat selection of adult woodland caribou were examined in relation to clear-cutting on summer range in east-central Newfoundland during 1987 – 1990. Expand
Hydroelectric development and the disruption of migration in caribou
Abstract We investigated the effects of hydroelectric development on the movements and space-use of caribou ( Rangifer tarandus caribou ) in west-central Newfoundland, Canada. We compared patterns ofExpand
REGULAR ARTICLES / ARTICLES RÉGULIERSFactors affecting the distribution and transmission of Elaphostrongylus rangiferi (Protostrongylidae) in caribou (Rangifer tarandus caribou) of Newfoundland,
The effects of herd density and climatic factors on parasite abundance were examined to understand the conditions necessary for such outbreaks of cerebrospinal elaphostrongylosis (CSE), a debilitating neurologic disease in Newfoundland. Expand
Study of changes in the abundance, vital rates, body size, and timing of migration of the Buchans Plateau caribou herd in Newfoundland, Canada found that Spring migration was significantly later and autumn migration significantly earlier, and it is surmise that these responses may reflect heightened density-dependent competition for summer forage. Expand
Body Size Variations in Caribou Ecotypes and Relationships With Demography
It is hypothesize that the density-dependent effect observed on body size might have been exerted through summer habitat degradation and movement variations during herd growth, and the correlations between population trajectories and changes in body condition and habitat. Expand
Habitat selection and demography of a nonmigratory woodland caribou population in Newfoundland
It is suggested that black bears need to be considered more seriously as a factor influencing coarse-scale habitat selection and demography in woodland caribou herds in Newfoundland. Expand
Potential mechanisms of phenotypic divergence in body size between Newfoundland and mainland black bear populations
It is predicted that body size should be larger in Newfoundland bears than in mainland populations, and that among the six populations, male body mass should scale hyperallometrically with female body mass. Expand
