This decommissioned ERA site remains active temporarily to support our final migration steps to https://ualberta.scholaris.ca, ERA's new home. All new collections and items, including Spring 2025 theses, are at that site. For assistance, please contact erahelp@ualberta.ca.

Anthropogenic influence on the autumn migration of polar bears (Ursus maritimus) in Hudson Bay
DownloadSpring 2022
Migratory species may shift established spatiotemporal patterns in response to anthropogenic impacts, so understanding the energetic consequences of behavioural plasticity may provide insight into how effectively migratory species respond to climate change. I used satellite telemetry to examine...

Factors Influencing Bioacoustically Derived Arrival Timing of Three Migrant Bird Species in the Western Boreal Forest
DownloadFall 2021
Habitat alteration is the leading cause of bird population declines globally. Therefore, understanding the processes influencing habitat selection are important for the identification and protection of important areas for birds. Long-distance migrant birds are particularly vulnerable and are...

Linking partial migration to endo- and ectoparasite infection of collared and uncollared elk (Cervus canadensis)
DownloadFall 2019
Ungulate ecology studies can focus on forage-predation interactions, but parasites also can have significant impacts on body condition, fecundity, and survival in ungulates. The effects of migration on parasite exposure are not well understood, but exposure may differ on allopatric summer ranges....

Long-term changes in migratory patterns of elk (Cervus canadensis) in the southern Rocky Mountain Trench of British Columbia, Canada
DownloadSpring 2021
Migration can be described as a round-trip movement between distinct ranges and is thought to be a response to a spatiotemporal variation in resources. Large vertebrate herbivores such as ungulates often migrate to track seasonal variability in high quality forage and reduce predation risk....

Spring 2020
Migration is a behavioral response to temporal variation in resources. While migration phenology is often predictable, phenology is expected to shift as climate change alters seasonal resource availability. We used data from satellite-linked telemetry collars on adult female polar bears (Ursus...

Fall 2019
The ability of species to adapt to the shifting environmental conditions associated with climate change will be a key determinant of their persistence in the coming decades. This is a challenge already faced by species in the Arctic, where rapid environmental change is well underway. Caribou and...

Seasonal habitat use, habitat selection, and migratory behaviours of Stone’s sheep (Ovis dalli stonei) in northern British Columbia, Canada
DownloadFall 2021
Habitats and migration corridors used by wildlife have become increasingly modified by anthropogenic disturbances, and in many cases have resulted in population declines and local extirpations. To conserve ungulate populations, management strategies often focus on identifying and mitigating...
