The roles of temperature and host plant interactions in larval development and population ecology of Parnassius smintheus Doubleday, the Rocky Mountain Apollo butterflyDownload
Alpine environments are harsh and unpredictable. Exogenous factors such as weather might therefore be expected to dominate processes affecting population dynamics of alpine organisms, relative to endogenous factors including plant-animal interactions. The alpine butterfly Parnassius smintheus...
Alpine tundra is notorious for its fragility and slow recovery following disturbance. Tourism is increasing in alpine areas, creating the need to improve our understanding of the impacts of recreation in these ecosystems. This study examined the impacts of hiking and off-highway vehicle use on...
Reclamation of northern disturbances is of increasing importance as industrial activities and associated infrastructure expands to accommodate growing human reliance on world ecosystems. Bryophytes are recognized as ecologically essential to northern ecosystems and effectively promoting their...
Soil development limits alpine plant establishment in recently-deglaciated terrain - Manuscript dataset
Soil development limits alpine plant establishment in recently-deglaciated terrain - Manuscript datasetDownload
Data files used for analyses in manuscript titled "Soil development limits alpine plant establishment in recently-deglaciated terrain". The original data was collected in 2016/2017 and analyzed to be included in MSc. thesis titled "Characteristics of alpine plants and soils along an elevational...
With a warming climate, northern ecosystems will face significant ecological changes such as permafrost thaw, increased frequency of forest fires, and shifting ecosystem boundaries including the spread of canopy-forming shrubs into tundra communities. A growing number of observations show...
A primary impediment to understanding how species diversity and anthropogenic disturbance are related is that both diversity and disturbance can depend on the scales at which they are sampled. While the scale dependence of diversity estimation has received substantial attention, the scale...
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,...
Perspectives on Large Volume & Diverse Data Sets: Tundra and Climate Interactions in the Southwest YukonDownload
Presentation given at the 2012 University of Alberta Campus Data Summit, March 22-23, 2012.
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...
Limited impacts of extensive human land use on dominance, specialization, and biotic homogenization in boreal plant communitiesDownload
Background Niche theory predicts that human disturbance should influence the assembly of communities, favouring functionally homogeneous communities dominated by few but widespread generalists. The decline and loss of specialists leaves communities with species that are functionally more similar....
