Records of atmospheric mercury deposition and post-depositional mobility in peat permafrost archives from central and northern Yukon, Canada
DownloadFall 2017
Environmental archives provide a feasible means for studying the biogeochemical cycling of heavy metals including mercury (Hg). Although many temperate peat bogs have been successfully used to reconstruct natural and anthropogenic atmospheric Hg deposition fluxes, northern circumpolar permafrost...

Shrub encroachment in arctic and alpine tundra: Patterns of expansion and ecosystem impacts.
DownloadFall 2011
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...

Anthropogenic noise is increasingly widespread as human development continues. Noise can negatively affect humans and wildlife, but the most deleterious effects are incurred by species that rely on vocal communication for mating, territory defence, and other vital functions. Songbirds are...

The impact of recreational activities on an alpine vascular plant community in the Canadian Rockies
DownloadFall 2010
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...

The roles of temperature and host plant interactions in larval development and population ecology of Parnassius smintheus Doubleday, the Rocky Mountain Apollo butterfly
DownloadFall 2011
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...
