Ferruginous Hawk (Buteo regalis) response to energy development and inclement weather in southern Alberta
DownloadSpring 2021
Growing global energy demand is projected to increase by nearly 30% in coming decades. As such, wildlife is increasingly required to persist in altered landscapes resulting from energy-related changes and development. In breeding birds, anthropogenic structures are often used as perches and, in...

Fall 2015
Specialist predators with a limited diet may be less adaptable to environmental change than generalists, which consume a diversity of prey. As the climate changes, ecological homogenization is occurring, where generalist species outcompete specialists, reducing ecosystem complexity. In Arctic...

Spring 2014
The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. Yet this relationship lacks both consensus in theoretical expectations and consistency in observed empirical patterns. I present one of the largest extent studies...

Limnology of a Large Northern Lake (Lhù’ààn Mânʼ [Kluane Lake], Yukon) in an Era of Reconciliation and Rapid Climate Change
DownloadSpring 2022
Almost 60% of Canada’s freshwater drains North, where air temperatures are increasing at twice the global rate. Despite the exposure of northern lakes to higher rates of change and their ecological, hydrological, and cultural importance, baseline knowledge and monitoring of their water properties...

Local and regional demography in a migratory forest songbird and effects of forest management intensity
DownloadSpring 2014
The numerical response of forest birds to habitat alteration has been well documented in North America, but the underlying demographic processes driving these changes remain largely unknown. Among species sensitive to such alterations, the Ovenbird (Seiurus aurocapilla) shows one of the largest...

Spring 2018
Climate change will continue to affect the Arctic more intensely than other biomes. These changes can have dramatic effects on biotic interactions that influence the functioning of these systems, including plant-herbivore interactions. Invertebrate herbivores strongly depend on external...

Spring 2013
The Rocky Mountain apollo butterfly, Parnassius smintheus, and its host-plant Sedum lanceolatum, are endemic to open alpine meadows threatened by the encroachment of trees. I explore variability in interactions between P. smintheus and S. lanceolatum relative to the treeline-delimited meadow...

Polar bear (Ursus maritimus) foraging, spatial, and energetics ecology in the changing Arctic
DownloadFall 2020
Climate warming in the Arctic has resulted in rapid and extensive changes to sea ice dynamics and profound ecological impacts, including changes to the timing of life history events, community structure, and food web dynamics. Sea ice-dependent species such as polar bears (Ursus maritimus) are...

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,...

Projecting boreal bird responses to climate change considering uncertainty, refugia, vegetation lags, and post-glaciation history
DownloadSpring 2016
Often referred to as North America’s bird nursery, the boreal forest biome provides a productive environment for breeding birds, supporting high species diversity and bird numbers. These birds are likely to shift their distributions northward in response to rapid climate change over the next...
