In wildlife conservation, long-term monitoring is often justified by wildlife agencies as they allow managers to inform stakeholders, avoid conflicts, and to evaluate the results of management interventions. However, many wildlife agencies insufficiently or inadequately use these data in their...

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....

Partial migration, a phenomenon wherein only one fraction of a population migrates, is taxonomically widespread. While well-studied in birds and fish, partial migration in large herbivores only recently has come into the spotlight due to migratory ungulates’ global loss. In this dissertation, I...

Ungulates are known to avoid predation by grouping up, increasing vigilance, and reducing residency time among preferred habitats. Similarly, shifting return rates may represent a means of pre-emptively minimizing exposure to risk by being less predictable on the landscape to predators. We...
