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...

Migration watches were conducted from 21 August to 15 October 1984 near the site of Syncrude Canada Ltd.' s bitumen mining, extraction and upgrading development north of Fort McMurray, Alberta. These watches were undertaken to complement studies of birds using the waterbodies in the area of the...

Nutritional Significance of Wapiti (Cervus elaphus) Migrations to Alpine Ranges in Western Alberta, Canada
Download1989
Morgantini, L.E., Hudson, R.J.
This study was designed to provide a better understanding of the nutritional significance of wapiti (Cervus elaphus) migrations from low-elevation winter ranges onto high-elevation alpine summer ranges. The study focused on a population along the east slopes of the Rocky Mountains in western...

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...

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....

McLachlan, J. S., Lewis, M. A., HilleRisLambers, J., Clark, J. S.
Recent literature on plant population spread advocates quantification of long-distance dispersal (LDD). These estimates could provide insights into rates of migration in response to climate change and rates of alien invasions. LDD information is not available for parameterization of current...

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...

Mercer, G., St. Clair, C. C., Whittington, J.
Increasing levels of human activity in mountainous areas have high potential to inhibit animal movement across and among valleys. We examined how wolves respond to roads, trails, and other developments. We recorded the movements of two wolf packs for two winters by following their tracks in the...
