The Ecology, Neoichnology and Sedimentology of Siliciclastic Hardground Communities: Implications for Trypanites Assemblages in the Rock RecordDownload
The paleoecology of rocky substrates in the rock record is commonly interpreted based on ichnology (the Trypanites ichnofacies) and is frequently associated with a biotic assemblage with low diversity. However, analyses of two modern, siliclastic, intertidal hardground community at Lion Rock,...
The Biogeography of Ground Beetles (Coleoptera: Carabidae) on the Islands of Lac la Ronge, Saskatchewan, CanadaDownload
Islands offer unusual opportunities for studying theoretical concepts in ecology. I studied the role of island size and isolation in structuring assemblages of ground beetles (Coleoptera: Carabidae) on the islands and adjacent mainland of Lac la Ronge, Saskatchewan, Canada. Carabid beetles were...
Festuca hallii (plains rough fescue), a late-seral bunchgrass and long-lived perennial, is difficult to restore once disturbed. Once dominant in grasslands throughout central Alberta, F. hallii now occurs in remnants, a result of agricultural and residential development, and oil and gas...
Glass sponge reefs are globally unique ecosystems on Canada’s western continental shelf that are susceptible to harm from fishing (e.g., bottom-contact trawling). In 2017, a marine protected area (MPA) was created to protect four of these reefs in Hecate Strait and Queen Charlotte Sound. Three...
Polar bears (Ursus maritimus) enter a period of intensified feeding in the spring, which allows for the accumulation of energy stores critical to surviving the open water season. Study on polar bear predation has been limited by sample size and spatial extent, and hypotheses on the demographic...
The Rocky Mountain apollo butterfly, Parnassius smintheus, and its host-plant Sedum lanceolatum, are endemic to open alpine meadows threatened by the encroachment of trees. I explore variability in interactions between P. smintheus and S. lanceolatum relative to the treeline-delimited meadow...
Natural regeneration in the boreal forest: seedling establishment and success in western North American and European boreal forestsDownload
As the costs and ecological implications of intensive forest management rise, alternative management strategies that minimize intervention become more desirable options, particularly natural regeneration. Two locations were studied: the boreal mixedwoods of western North America (Alberta) and...
Microbiota are ubiquitous in nature. Similarities as well as differences are present between microbiota in animals and fermentation systems. The aim of the PhD project was to investigate factors affects microbial ecology in rodent and sourdough models. To determine how compromised health of the...
Landscape Ecology of Mule Deer (Odocoileus hemionus) and White-tailed Deer (O. virginianus) with Implications for Chronic Wasting DiseaseDownload
Chronic wasting disease (CWD) is a fatal prion disease of cervids that continues to spread into new regions of Canada despite containment efforts. I examine the importance of landscape connectivity using circuit theory and source/sink habitats that are based on selection, survival and...
