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...

Fall 2010
Dematiaceous hyphomycetes are a taxonomically diverse artificial assemblage of conidial fungi that have dark pigments known as melanins in their walls. Select dematiaceous hyphomycetes from the Coniochaetales, Pleosporales, and Helotiales obtained from arctic and alpine bryophytes and vascular...

Examination of Wet Meadow Creation as a Restoration Option for Extracted Peatland Sites in Alberta
DownloadSpring 2014
Question: Can a wet meadow plant community be established on abandoned peatlands through broadcast plant diaspore spreading in western Canada? Does fertilization impact the development and establishment of the wet meadow? Location: Evansburg, Alberta, Canada Methods: Wet meadow vascular and...

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...

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...

New insights about barnacle reproduction: Spermcast mating, aerial copulation and population genetic consequences
DownloadSpring 2014
Barnacles are mostly hermaphroditic and they are believed to mate via copulation or, in a few species, by self-fertilization. However, isolated individuals of two species that are thought not to self-fertilize, Pollicipes polymerus and Balanus glandula, nonetheless carried fertilized...

Physiological, ecological and environmental factors that predispose trees, stands and landscapes to infestation by tree-killing Dendroctonus beetles
DownloadSpring 2013
In the last century the frequency and severity of outbreaks of tree-killing Dendroctonus beetles (Coleoptera: Curculionidae) have increased. Small-scale drivers within trees likely drive outbreak dynamics across landscapes. At a small scale, variation in carbohydrate availability within the stems...
