“These Trees Have Stories to Tell” Linking Denésƍliné Knowledge and Dendroecology in the Monitoring of Barren-ground Caribou Movements in the Northwest Territories, Canada
DownloadFall 2015
Grounded in an Indigenous methodological framework and using dendroecology as a scientific assessment tool in combination with oral history analysis, this thesis assesses changes to caribou movement patterns in the traditional territory of Lutsel K’e Dene First Nation (LKDFN), Northwest...

Geographic Information Systems as Communication Tools: Environmental Assessment and the Health Impacts of Natural Resource Developments on Circumpolar Indigenous Peoples
DownloadFall 2014
Introduction. The industrialization of circumpolar regions confronts a legacy of disproportionate bio-physical, socio-economic, heritage, and health impacts borne by indigenous populations. As natural resource development continues to accelerate in the north, concerns about impacts to the health...

Fall 2013
Subglacial bryophytes, entombed during the Little Ice Age (LIA, 150-580 years BP) beneath the polythermal Teardrop Glacier, Sverdrup Pass, Ellesmere Island, Nunavut, Canada, were examined. The diversity, paleoecological significance, and regeneration capacity of these bryophyte assemblages are...

The role of habitat quality and climate in the dynamics of occupancy and survival of a population of collared pikas (Ochotona collaris) in the Ruby Range, Yukon Territory
DownloadFall 2013
I examined the role of habitat quality and climate in the dynamics of occupancy and survival of a population of collared pikas in the Yukon Territory, Canada. Annual surveys of marked individuals over an 11 year period (1999 to 2009) within a geographically isolated metapopulation were used to...

Elevation dependent landscape processes in rapidly warming sub-Arctic mountains: influences of snow, temperature and vegetation
DownloadFall 2015
The loss of spring snow in the Northern Hemisphere has been dramatic. From 1967 to 2008 snow cover decreased by 14% in May and 46% in June, with a simultaneous reduction in snow cover duration of 6 – 8 days per decade in both summer and fall. These effects have been particularly pronounced in...

Niche partitioning and spatial variation in abundance of Rock (Lagopus muta) and White-tailed Ptarmigan (L. leucura): a case of habitat selection at multiple scales
DownloadSpring 2010
Climate change can affect habitat availability and species interactions at several spatial and temporal scales. I explored niche partitioning and spatial variation of Rock (Lagopus muta) and White-tailed Ptarmigan (L. leucura) in southwest Yukon. I examined habitat selection of foraging areas...

Characteristics of alpine plants and soils along an elevational gradient, Northern Selkirk Mountains, British Columbia
DownloadSpring 2019
Rates of climate change are accelerated at higher elevations, a pattern termed elevation-dependent warming (EDW). Consequently, the impacts of climate change on community patterning and soil development may be particularly evident in alpine environments. Alpine ecotone boundaries, such as...

Horns and hotspots: detecting change in mountain sheep populations over large spatiotemporal scales
DownloadSpring 2020
Long-term data is essential for addressing questions about how populations change over time in response to environmental variability, and natural and anthropogenic disturbance. Two species of mountain sheep (Ovis spp.) in Canada have been monitored over several decades and provided the data...

Population, individual and behavioural approaches to understanding the implications of habitat change for arctic ground squirrels
DownloadFall 2012
The ecological niche describes the entire set of resources and environmental conditions suitable for species to occur and persist. In northern ecosystems, rapid climate change appears to be altering these conditions and increasing the likelihood of shifts in distribution and abundance of species,...

The mating system, dispersal behavior and genetic structure of a collared pika (Ochotona collaris: Ochotonidae) population in the southwest Yukon, and a phylogeny of the genus Ochotona.
DownloadFall 2011
Pikas (Ochotona, Ochotonidae) are small, short-eared lagomorphs that inhabit steppes and mountains in northern and central Asia and alpine regions in western North America. I examined the dispersal patterns, genetic structure and mating system of a collared pika (O. collaris) population from the...
