A bryophyte perspective on forest harvest: The effects of logging on above- and below-ground bryophyte communities in coastal temperate rainforests
DownloadSpring 2013
This thesis examines patterns in bryophyte species richness and composition on the forest floor and in the soil diaspore bank of temperate rainforest stands which varied in time post-harvest. Quantitative data (abundance) was assessed in quadrats (25x25cm) on soil, decaying logs, and tree bases...

Conservation and ecology of bryophytes in partially harvested boreal mixed-wood forests of west-central Canada
DownloadFall 2010
This thesis examined the efficacy of residual forest structure for the preservation and recovery of bryophytes five to six years after partial canopy harvest in boreal mixed-wood forests of northwestern Alberta, Canada. Bryophytes were sampled in two forest types that differed in pre-harvest...

Fire history, landscape biodiversity and indicators for sustainable management of the boreal mixedwood forest
DownloadSpring 2012
I examined the response of invertebrate assemblages to the forest mosaic established by past fire events, and tested the performance of trees as biodiversity surrogates in accurately reflecting relationships between fire history and invertebrate assemblages. Over 80 % of the studied landscape...

After decades of recent fire exclusion in southern Alberta, Canada, forests are progressively aging and landscape mosaics are departing from their historical conditions. A large-scale fire history study spanning three natural subregions: Subalpine, Montane and Upper Foothills, was undertaken to...

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...

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...

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...

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...
