Characteristics of alpine plants and soils along an elevational gradient, Northern Selkirk Mountains, British ColumbiaDownload
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...
Elevation dependent landscape processes in rapidly warming sub-Arctic mountains: influences of snow, temperature and vegetationDownload
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...
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...
Geographic Information Systems as Communication Tools: Environmental Assessment and the Health Impacts of Natural Resource Developments on Circumpolar Indigenous PeoplesDownload
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...
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...
Niche partitioning and spatial variation in abundance of Rock (Lagopus muta) and White-tailed Ptarmigan (L. leucura): a case of habitat selection at multiple scalesDownload
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...
Population, individual and behavioural approaches to understanding the implications of habitat change for arctic ground squirrelsDownload
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,...
Resilient Space: Bighorn Sheep (Ovis canadensis) Ecological Resilience in the Northern Rocky MountainsDownload
Abstract Ecological resilience was defined, reviewed and discussed by synthesis of theory, concepts and empirical evidence presented in the primary literature (Chapter 1). Ecological resilience is concerned with ecological functions and the desirability of alternate states. Management and...
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.Download
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...
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 TerritoryDownload
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...
