Abstract: <p>The objective of this thesis is to better understand the demography and habitat selection of Newfoundland caribou. Chapter 1 provides a general introduction of elements of population ecology and behavioural ecology discussed in the thesis. In Chapter 2, I examine the causes of long-term fluctuations among caribou herds. My findings indicate that winter severity and density-dependent… more

Name(s): Creator (cre): Borlestean, Adrian, Thesis advisor (ths): Murray, Dennis L, Degree committee member (dgc): Frost, Paul C, Degree committee member (dgc): Dorken, Marcel E, Degree granting institution (dgg): Trent University
Abstract: <p>Population density regulation is a fundamental principle in ecology, however there remain several unknowns regarding the functional expression of density dependence. One prominent view is that the patterns by which density dependence is expressed are largely fixed across a species, irrespective of environmental conditions. Our study investigated the expression of density dependence in… more

Reintroducing species in the 21st century: incorporating climate change into translocation and de-extinction programs

Name(s): Creator (cre): Peers, Michael J L, Thesis advisor (ths): Murray, Dennis L, Degree committee member (dgc): Thornton, Daniel H, Degree committee member (dgc): Schaefer, James A, Degree granting institution (dgg): Trent University
Abstract: <p>Climate change has had numerous impacts on species' distributions by shifting suitable habitat to higher latitudes and elevations. These shifts pose new challenges to biodiversity management, in particular translocations, where suitable habitat is considered crucial for the reintroduced population. De-extinction is a new conservation tool, similar to reintroduction, except that the… more

Beyond Habitat: Individual and Population-Level Drivers of Coyote Space Use

Name(s): Creator (cre): Ellington, Edward Hance, Thesis advisor (ths): Murray, Dennis L, Degree committee member (dgc): Schaefer, James A, Degree committee member (dgc): Patterson, Brent R, Degree granting institution (dgg): Trent University
Abstract: <p>My objective was to understand how individual variation, in conjunction with variation in habitat, can affect individual and population-level variation in animal space use. I used coyotes (Canis latrans) as a model species to investigate the roles of hybridization, an inherited intrinsic factor, and spatial memory, a learned intrinsic factor, on space use. I used a diversity of methods… more
