Welcome to our lab page! We have a number of cool studies on the go: exciting projects looking at various aspects of behavioural and population ecology, evolutionary ecology, community ecology, and conservation and management. We maintain a major research program on the population dynamics of woodland caribou of the Saskatchewan Boreal Shield, including habitat responses to disturbance (especially fire) and the movements of caribou predators (wolves and black bears). We also have several projects associated with the outdoor laboratory of Sable Island, Nova Scotia (ongoing since 2007). Most recently, we have initiated a new research program on the management and ecology of the feral horses of the Alberta foothills. Recently complete projects include those on white-tailed deer in Manitoba and effects of density and hunting on moose of Gros Morne National Park in Newfoundland. Click on the teaching link if you are interested in the courses that I instruct each year in the Department of Biology. Feel free to contact us to discuss potential opportunities for work or if you have any questions.

About Me

I am an Associate Professor in the Department of Biology at the University of Saskatchewan in Saskatoon, SK, Canada (hired 2007). I am a broadly trained quantitative ecologist working on problems of pure and applied animal ecology. My research is field-based and largely empirical. I would consider myself a ‘population ecologist’, although my program touches on several aspects of ecology and evolution. For example, in trying to understand the basis of population dynamics for the wild horses of Sable Island, we are considering inter-specific links presented by grey seal and seabird inputs of nitrogen into the terrestrial system to affect plant diversity, forage, and subsequently horse space-use and demography. For our study of boreal caribou, we are taking a ‘whole ecosystem’ approach to the study of caribou population dynamics, tackling questions of habitat recovery after forest fire and interactions between caribou and their predators.

I have always been interested in habitat selection, especially how individual performance (e.g., survival and reproduction) can be influenced by an animal’s access to habitat resources and associated resource covariates, and demonstrating how these relationships might be modified by ecological processes (e.g., competition, predation, ecological succession, and cross-generational effects). I also dabble a bit on the molecular side of things, for example we are now hoping to quantify stress for individual horses of Sable Island (from cortisol in hair) and relate this to individual behaviour and performance. I also maintain an interest in population genetics; a very promising avenue to pursue concerning the Sable Island horses, where we are initiating brand-new research to establish the multi-generational pedigree of the horses and tackle questions about the micro-evolutionary processes that we believe are occurring (including sexual selection, horse colouration patterns) along a west-east gradient of habitat quality and density along the length of the island.  We are very excited about our work on genetics in the horses, which is seeing us expand our program to examine interesting questions of inbreeding and conservation genetics, and individual variation in gut microbial diversity and links with the island’s pedigree–even questions of antimicrobial resistance patterns in the Sable population (which is unique among populations considering its isolation and lack of history of modern veterinary care, including administration of antibiotics).
The effects of density on individuals to affect population-level processes is particularly fascinating to me, and almost all of my projects touch on this to some extent. Some recent studies include effects of population density on interaction rates between individuals, which may influence the spread of wildlife disease, density-dependent habitat selection, and effects of density on dispersal, sex ratios, and intensity of mate competition and sexual selection. By examining individual responses (be it behaviour or morphology) to population-level phenomena like overcrowding or predation we may be able to identify opportunities for selection. My interests further include individual- and matrix-based models of populations with applications to theory, conservation, and management; scaling and sampling questions in ecology; population-level ecological genetics; and of course natural history. My questions have been primarily directed at the ecology of European and North American mammals and birds, including populations of red deer, roe deer, caribou, feral horses, wolves, grizzly bears, polar bears, seals, turkey vultures, and prairie hawks (Swainson’s and ferruginous hawks).

I absolutely love Saskatchewan! It is a fantastic place to live and work. I reside in the town of Warman (just outside of the city of Saskatoon) with my wife and (now) four children.
