Sustaining the Recovery of Lake Sturgeon (Acipenser fulvescens) in the North Saskatchewan River of Alberta
DownloadSpring 2016
Nearly all Lake Sturgeon (Acipenser fulvescens) populations across North America have experienced losses to historic abundances estimated to be > 99%. This species is especially vulnerable to overharvest, habitat degradation, river fragmentation from dams, and is slow to recover due to life...

Territoriality is a phenomenon exhibited throughout nature. On the individual level, it is the processes by which organisms exclude others of the same species from certain parts of space. On the population level, it is the segregation of space into separate areas, each used by subsections of the...

Syncrude Canada Ltd. Lease 17 is located in the boreal mixedwood forest ecosystem. It lies within an area of moderately-low biological productivity. Thirty per cent of the lease is in the muskeg habitat type. The winter climate is severe. Energy cycling between soils, plants and animals occurs...

Camera traps are an increasingly popular tool for wildlife management. Studies that use detection rates as a simple index of relative abundance assume that movement is not density-dependent. More complex techniques such as spatially-explicit capture recapture models, occupancy models, or...

The Influence of Land-cover Type and Vegetation on Nocturnal Foraging Activities and Vertebrate Prey Acquisition by Burrowing Owls (Athene cunicularia).
DownloadFall 2012
Studies of habitat selection by foraging animals assume patterns of animal presence correlate with successful foraging, without explicit evidence this is valid. I used GPS dataloggers and digital video recorders to determine precise locations where nocturnally foraging Burrowing Owls captured...

Understanding how populations are structured and how they use natural and anthropogenic spaces is essential for effective wildlife management. A total of 510 barren-ground (Rangifer tarandus groenlandicus), 176 boreal (R. t. caribou), 11 mountain woodland (R. t. caribou), and 39 island (R. t....

Walking in Their Footsteps: New Approaches to Identify Behavioural Processes and Define Home Ranges Using Animal Movement Data
DownloadFall 2014
Animal movement and space-use patterns influence the distribution and abundance of species, predator-prey interactions, and many other ecological processes. Different approaches are used to study individual's space-use strategies and each approach suffers from unique challenges. The mechanistic...

Wolverine (Gulo gulo luscus) movement, habitat selection, and foraging in a landscape with resource extraction
DownloadFall 2017
Industrial infrastructure and activities can fragment boreal landscapes and alter the ecology of wildlife species. Wolverines (Gulo gulo luscus) are a species considered especially sensitive to resource extraction because wolverines are wide-ranging, low-density, and have low-reproductive rates....
