The sociogenetic structure of woodland caribou was explored using non-invasive fecal sampling. Fecal pellet sampling occurred in South Jasper during the fall of (2006 to 2012) and in North Interlake during the winter (2004 to 2010). Samples were amplified at 10 microsatellite loci and unique individuals identified. We used fecal pellet morphometrics and measured fecal reproductive hormone levels to distinguish calf from adult age-classes of woodland caribou. In addition, we conducted pedigree analysis of South Jasper caribou using the COLONY 2.0 program. Results demonstrated that pellet morphology, pregnane, and testosterone were able to differentiate age-class. Additionally, South Jasper caribou herds exhibited a polygynous mating system whereby few males dominated the reproductive output (only 20%) and female reproductive output was evenly distributed (39%). This study demonstrates the ability of non-invasive fecal methods to answer important questions pertaining to the age-class, mating system and fitness of woodland caribou.

Delineating population units is essential for the conservation and management of a species. Applying a genetic approach to delineate units, this study identifies genetic population structure, and landscape resistance to gene flow, of the nationally threatened boreal woodland caribou (Rangifer tarandus caribou) across the ecotypes’ southern range in Saskatchewan. Three genetic clusters were delineated across the study area, with moderate genetic connectivity identified with Manitoba. Isolation-by-distance was found to be significant across Saskatchewan, and within each genetic cluster. Gene flow across clusters in Saskatchewan was high (FST = ~0.01), with genetic connectivity being lowest for the south-central cluster surrounding Prince Albert National Park (FST = ~0.03). Resistance to gene flow was identified with the following landscape variables: water, forestry, roads, wildfire, and low suitability habitat. Careful consideration of these variables in range planning will help to maintain genetic connectivity of boreal caribou across its southern range in Saskatchewan. / May 2016

Woodland caribou are listed as a threatened species in Saskatchewan. The need for contemporary data is paramount for conservation of this species. There has been a dramatic increase in the number of threats to woodland caribou: forestry and logging, road development and expansion, mineral exploration and other long term changes to the landscape. Despite previous research effort, the current distribution and critical habitat of woodland caribou in north-central Saskatchewan is still poorly understood. Drawing upon the knowledge of a selected target group, interviews have been conducted to attain local and traditional knowledge on woodland caribou. Local knowledge has been used to identify key information about woodland caribou critical habitat and ecology in the north central region and more remote areas. Through the objectives of this research we have been able to identify current and historical abundance patterns; adult and calf biology; predator prey interactions; human activity on the landscape and potential effect on woodland caribou ecology; and weather/fire patterns and the potential effect on woodland caribou distribution. The significance of this type of research is critical in understanding woodland caribou biology in northern and remote areas. In addition, this project recognizes contributions and involvement of Aboriginal peoples in academic and government research initiatives.

Disturbance can provoke a chronic (long-term) stress response in wildlife, and can contribute to population declines. I examined the stress response of boreal woodland caribou, moose, and wolves to disturbance in eastern Manitoba by measuring cortisol concentrations in hair. Caribou cortisol concentrations were greatest for the three most southern populations, and increased with decreasing home range size. Intermediate logging (6-21 years) provided the best explanation for individual variation in caribou cortisol concentrations. Disturbance did not affect moose cortisol concentrations, but cortisol concentrations were higher in moose killed by wolves than moose collected by humans, suggesting that chronic stress in moose is linked to poor body condition and increased vulnerability to wolf predation. Wolf cortisol concentrations increased in 2012 and 2013 compared to 2011 following increased harvest pressure, and were higher in females. However, neither winter severity nor variation in wolf diet affected wolf cortisol concentrations. / October 2016

The Slate Islands caribou (Rangifer tarandis caribou) is an insular population which has experienced several population crashes and has been described as likely to succumb to extirpation. While a great deal of research has been conducted on mainland woodland caribou, factors which influence caribou distributions may differ between island and main land populations. In this thesis, I investigate relationships between habitat, landscape, anthropogenic features, population size, predation and spatial distribution of woodland caribou across the Slate Islands Provincial Park (Ontario) at the forest-patch spatial scale. Generalized linear models were used to compare observed caribou locations to available locations across the park, based on data from 1978 to 1995. Results indicated that the Slate Islands caribou selected deciduous cover, larger forest patches, areas further to water, flatter areas, lower elevations and areas closer to anthropogenic features. Population size had a limited effect on caribou distributions. / October 2015
