Polar bear (Ursus maritimus) foraging, spatial, and energetics ecology in the changing Arctic
DownloadFall 2020
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...

Fall 2017
Camera traps are an increasingly popular tool for wildlife management. Studies that use detection rates as a simple index of relative abundance assume that movement is not density-dependent. More complex techniques such as spatially-explicit capture recapture models, occupancy models, or...

Fall 2017
American black bears (Ursus americanus) and grizzly bears (U. arctos) have similar habitat requirements, relying on seasonally available grasses, forbs, fruiting shrubs and trees, and neonate ungulates. To avoid aggressive encounters with grizzly bears, black bears partition habitats spatially...

Sustaining the Recovery of Lake Sturgeon (Acipenser fulvescens) in the North Saskatchewan River of Alberta
DownloadSpring 2016
Nearly all Lake Sturgeon (Acipenser fulvescens) populations across North America have experienced losses to historic abundances estimated to be > 99%. This species is especially vulnerable to overharvest, habitat degradation, river fragmentation from dams, and is slow to recover due to life...

Territoriality is a phenomenon exhibited throughout nature. On the individual level, it is the processes by which organisms exclude others of the same species from certain parts of space. On the population level, it is the segregation of space into separate areas, each used by subsections of the...

Polar Bear (Ursus maritimus) Habitat, Space Use,and Movements in a Seasonal Sea Ice Ecoregion
DownloadFall 2015
Polar bears (Ursus maritimus) are sea ice habitat specialists and climate change has affected sea ice throughout this species’ circumpolar range. The annual phenological cycle of sea ice growth and decay is a strong influence on polar bear distribution and ecology. Study of the habitat selection,...

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...

Metrics for Assessing Fisheries Productivity and Offsetting Strategies under Canada’s New Fisheries Act
Download2014-12-23
Poesch, M., Christensen-Dalsgaard, K.K., Sinnatamby, R.N.
The Alberta oil sands region contains one of the world’s largest oil deposits, estimated at 1.7 trillion barrels. Development in this region can have negative effects for aquatic species, governed under Canada’s Fisheries Act. The Fisheries Act allows the possibility for offsetting losses in...

Walking in Their Footsteps: New Approaches to Identify Behavioural Processes and Define Home Ranges Using Animal Movement Data
DownloadFall 2014
Animal movement and space-use patterns influence the distribution and abundance of species, predator-prey interactions, and many other ecological processes. Different approaches are used to study individual's space-use strategies and each approach suffers from unique challenges. The mechanistic...

Eaton, B.R., Fisher, J.T., McKenna, G.T., Pollard, J.
Oil sands companies are required to reclaim the land that has been disturbed during their operations to self-sustaining, locally common boreal forest. An important facet of the reclaimed landscape is support of locally-relevant wildlife communities. Wildlife communities are an important part of...
