Clark, James S., Lewis, Mark A., Horvath, Lajos
For populations having dispersal described by fat‐tailed kernels (kernels with tails that are not exponentially bounded), asymptotic population spread rates cannot be estimated by traditional models because these models predict continually accelerating (asymptotically infinite) invasion. The...

Paquet, P.C., Hik, D.S., Frame, P.F., Cluff, H.D.
Wolves (Canis lupus) on the Canadian barrens are intimately linked to migrating herds of barren-ground caribou (Rangifer tarandus). We deployed a Global Positioning System (GPS) radio collar on an adult female wolf to record her movements in response to changing caribou densities near her den...

Managing the cumulative impacts of land uses in the Western Canadian Sedimentary Basin: A modeling approach.
Download2003
Wasel, S., Schneider, R., Boutin, S., Stelfox, J.
This case study from northeastern Alberta, Canada, demonstrates a fundamentally different approach to forest management in which stakeholders balance conservation and economic objectives by weighing current management options from the point of view of their long-term effects on the forest....

Patterns in the species composition and richness of fish assemblages in northern Wisconsin lakes
Download1982
Fish assemblage structure, and factors and mechanisms appearing important in the ecological maintenance of these structures, were examined for 18 small lakes in northern Wisconsin during summer and winter. The study was focused around the following questions. Are there discrete, repeatable groups...

Derocher, Andrew E., Auger-Méthé, Marie, DeMars, Craig A.
This the data associated with the manuscript: Auger-Méthé, M, AE Derocher, DA DeMars, MJ Plank, EA Codling, MA Lewis. Evaluating random search strategies in three mammals from distinct feeding guilds. Journal of Animal Ecology. In Press. The data is the step lengths and turning angles measured...

Predicting local and nonlocal effects of resources on animal space use using a mechanistic step-selection function.
Download2013
Schaefer, J., Bastille-Rousseau, G., Murray, D., Lewis, M.A., Potts, J.R.
Predicting space use patterns of animals from their interactions with the environment is fundamental for understanding the effect of habitat changes on ecosystem functioning. Recent attempts to address this problem have sought to unify resource selection analysis, where animal space use is...

Habitat protection has been identified as an important strategy for the conservation of woodland caribou (Rangifer tarandus). However, because of the economic opportunity costs associated with protection it is unlikely that all caribou ranges can be protected in their entirety. We used an...

Short-Term Effects of Timber Harvest on Abundance, Territory Characteristics, and Pairing Success of Ovenbirds in Riparian Buffer Strips
Download2000
Hannon, Susan, J., Lambert, J. Daniel
In managed forests, riparian buffer strips typically are maintained to protect water quality. If properly designed, buffer strips also may act as wildlife reserves. However, forest managers have lacked the information to develop standards for buffer strips to maximize benefits for wildlife...

Trade-offs between predation risk and forage differ between migrant strategies in a migratory ungulate
Download2009
Trade-offs between predation risk and forage fundamentally drive resource selection by animals. Among migratory ungulates, trade-offs can occur at large spatial scales through migration, which allows an \"escape'' from predation, but trade-offs can also occur at finer spatial scales. Previous...

Triage for conserving populations of threatened species: The case of woodland caribou in Alberta.
Download2010
Hauer, G., Adarnowicz, W., Boutin, S., Schneider, R.
Prioritization of conservation efforts for threatened and endangered species has tended to focus on factors measuring the risk of extirpation rather than the probability of success and cost. Approaches such as triage are advisable when three main conditions are present: insufficient capacity...
