The boreal ecotype of woodland caribou (Rangifer tarandus caribou) is federally listed as Threatened due to population declines throughout its distribution. High mortality rates of neonate calves (≤ 4 weeks old) due to predation are a key demographic factor contributing to population declines...

Characterizing adaptive morphological features and resource selection of Rocky Mountain Sculpin (Cottus sp.), a species at risk in Canada
DownloadFall 2017
Freshwater biodiversity is presently one of the world’s largest conservation concerns. Both direct and indirect human activities contributing to waterway modifications, climate change, and habitat alteration are causing major declines in freshwater fish species richness and abundance. While these...

Understanding the underlying mechanisms driving population demographics such as species-habitat relationships and the spatial scale in which these relationships occur is essential for developing optimal management strategies. Here we evaluated how landscape characteristics and winter severity...

Detecting minimum energy states and multi-stability in nonlocal advection–diffusion models for interacting species

Deriving emergent patterns from models of biological processes is a core concern of mathematical biology. In the context of partial differential equations, these emergent patterns sometimes appear as local minimisers of a corresponding energy functional. Here we give methods for determining the...

Disentangling the relative effects of structural complexity and substrate composition on fish habitat selection in coral reef environments
DownloadFall 2021
Identifying features of biogenic habitats (i.e. made of living plants and animals) that attract and retain resident species is a key theme in ecology with important implications for habitat conservation and restoration. Using corals (class Anthozoa, phylum Cnidaria) —a group of foundational...

Effects of hunting on the demographics, movement, and habitat selection of American black bears (Ursus americanus)
Download2008
I conducted a large-scale experiment to determine the effects of hunting on the demographics and behaviour of American black bears (Ursus americanus ). I monitored 290 bears, a subset of which were equipped with VHF and GPS radio-collars, in 2 hunted areas and an adjoining unhunted area in the...

Searching allows animals to find food, mates, shelter and other resources essential for survival and reproduction and is thus among the most important activities performed by animals. Theory predicts that animals will use random search strategies in highly variable and unpredictable environments....

The persistence of forest-dependent species in fragmented landscapes is fundamentally linked to the movement of individuals among subpopulations. The paths taken by dispersing individuals can be considered a series of steps built from individual route choices. Despite the importance of these...

The purpose of our study is to show how ecologists' interpretation of habitat selection by grizzly bears (Ursus arctos) is altered by the scale of observation and also how management questions would be best addressed using predetermined scales of analysis. Using resource selection functions (RSF)...
