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...

Benthic Responses to Nitrogen and Phosphorus Deposition on Alpine Ponds in Banff National Park: A Replicated Whole-Ecosystem Experiment
DownloadFall 2012
Nitrogen (N) and Phosphorous (P) deposition at high elevations has increased by 40% over the last fifteen years, causing concern for the 3000+ alpine ponds in Banff National Park. A novel whole-ecosystem experiment was used to test for the effects of elevated N and P deposition on benthic...

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...

Spring 2016
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...

Fall 2009
This study investigates the interactions between carbon dioxide, climate, and glaciers of the Canadian Rockies under a relatively conservative IPCC emission scenario for the 21st century through the use of the PSU/NCAR MM5 mesoscale model (MM) nested within the Princeton GFDL global...

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...

Spring 2016
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...
