Spring 2015
Polar bears (Ursus maritimus) enter a period of intensified feeding in the spring, which allows for the accumulation of energy stores critical to surviving the open water season. Study on polar bear predation has been limited by sample size and spatial extent, and hypotheses on the demographic...

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...

Spring 2014
Sea ice in Hudson Bay is melting earlier and freezing later as the climate warms, resulting in declines in the condition, survival, and population size of polar bears (Ursus maritimus) in the Western Hudson Bay population. The objectives of this study are to analyze temporal variation in...

Chai, S-L., Eaton, B., Fisher, J.T., Muhly, T.
The North American beaver (Castor canadensis) is a large semi-aquatic rodent that has played a central role in shaping the Canadian boreal landscape, and colonial Canadian history. Exploitation of North American beaver populations to supply the European hat industry spurred the westward...

Reexamining Sample Size Requirements for Multivariate, Abundance-Based Community Research: When Resources are Limited, the Research Does Not Have to Be
Download2015-01-01
Forcino, F. L., Leighton, L. R., Twerdy, P., Cahill, J. F.
Community ecologists commonly perform multivariate techniques (e.g., ordination, cluster analysis) to assess patterns and gradients of taxonomic variation. A critical requirement for a meaningful statistical analysis is accurate information on the taxa found within an ecological sample. However,...

Boutin, S., He, F., Sólymos, P., Cahill Jr, J. F., Mayor, S.J.
The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. The 'intermediate disturbance hypothesis' suggests that disturbance regimes generate predictable non-linear patterns in species richness. Evidence often contradicts...

Responses in butterflies to loss and fragmentation of boreal forests from in situ oil sands
DownloadSpring 2019
Anthropogenic loss and fragmentation of habitat are a threat to biodiversity, while increasing demands for energy have made the provision of fossil fuels an important source of disturbance to habitats around the globe. In Alberta, Canada, the extraction of a 142,000 km2 oil sands reserve is...

Fall 2018
Glass sponge reefs are globally unique ecosystems on Canada’s western continental shelf that are susceptible to harm from fishing (e.g., bottom-contact trawling). In 2017, a marine protected area (MPA) was created to protect four of these reefs in Hecate Strait and Queen Charlotte Sound. Three...

Melim, Leslie A., Northup. Diana E., Spilde, Michael N., Jones, Brian, Boston, Penelope J., Bixby, Rebecca J.
We report on a reticulated filament found in modern and fossil cave samples that cannot be correlated to any known microorganism or organism part. These filaments were found in moist environments in five limestone caves (four in New Mexico, U.S.A., one in Tabasco, Mexico), and a basalt lava tube...
