Stable home ranges can emerge in a generic forager using a two-part memory system and rules derived from optimal foraging theory. My objective was to evaluate the underlying assumptions of this promising theoretical model using data from two populations of elk. Using a spatiotemporal scan...

The purpose of our study is to show how ecologists' interpretation of habitat selection by grizzly bears (Ursus arctos) is altered by the scale of observation and also how management questions would be best addressed using predetermined scales of analysis. Using resource selection functions (RSF)...

The western toad (Anaxyrus boreas, formerly Bufo boreas) is one of many amphibian species considered to be at risk of extinction (COSEWIC status is Special Concern). I examined habitat use patterns of the western toad using several methods to gain a better understanding of its habitat...

Northern form Dolly Varden char (Salvelinus malma malma) inhabit cold-water streams in the western Canadian Arctic. They are an important cultural and subsistence resource to local Aboriginal communities, yet little is known about their complex early life histories. Populations of Dolly Varden...

The relationship between individual performance and nonrandom use of habitat is fundamental to ecology; however, empirical tests of this relationship remain limited, especially for higher orders of selection like that of the home range. We quantified the association between lifetime reproductive...

Roads are a prevalent, ever-increasing form of human disturbance on the landscape. In many places in western North America, energy development has brought human and road disturbance into seasonal winter range areas for migratory elk. In this population, I studied individual habitat selection...

Climate warming in the Arctic has resulted in rapid and extensive changes to sea ice dynamics and profound ecological impacts, including changes to the timing of life history events, community structure, and food web dynamics. Sea ice-dependent species such as polar bears (Ursus maritimus) are...

Belikov, S. E., Maslanik, J., Aars, J., Born, E. W., Amstrup, S. C., Serreze, M. C., Stirling, I., Wiig, O., Nielson, R. M., DeWeaver, E., Durner, G. M., Bailey, D. A., McDonald, T. L., Mauritzen, M., Holland, M. M., Derocher, A. E., Douglas, D. C.

Projections of polar bear (Ursus maritimus) sea ice habitat distribution in the polar basin during the 21st century were developed to understand the consequences of anticipated sea ice reductions on polar bear populations. We used location data from satellite-collared polar bears and...

Animals face trade-offs throughout life between competing functions, such as between self-maintenance, reproduction, and survival. Resource allocation between these competing functions leads to different patterns of life history traits, changes in investment in reproductive effort, and different...

Cougar (Puma concolor) range is expanding eastward in North America. Understanding how range expansion is occurring in a human-dominated landscape is needed to manage the social and ecological implications of a returning large carnivore. To address this, I used GPS-radio collars and...
