Abstract: <p>Population cycles are characterized by predictable temporal oscillations in population size and are influenced by densities of both predators and prey. These oscillations are influenced by the predator functional response, i.e. the influence of prey density on predator kill rate. The Canada lynx (Lynx canadensis) is a predatory mammal with cyclic northern populations driven by snowshoe… more Full Text: Behavioural responses of Canada lynx (Lynx canadensis) to cyclic declines in the snowshoe hare (Lepus americanus) A Dissertation Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Doctor of …

Hares exhibited variable movement and activity during the cycle, exhibiting increased home range size and higher daily displacement during low population densities. Males exhibited more dramatic… more Full Text: SUMMER MOVEMENT ECOLOGY OF SNOWSHOE HARES (LEPUS AMERICANUS) DURING A POPULATION CYCLE A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Masters of Science in the Faculty of Arts and …

Abstract: <p>Estimation of population abundance from samples has inherent practical challenges. Moreover, analytical methods to estimate abundance may vary in statistical assumptions and prediction uncertainties. I evaluated the performance of design-based and model-based methods to estimate Canada geese (Branta canadensis) abundance based on aerial fixed-width transect surveys in the Hudson Bay… more Year: 2024, 2024
