Biogeographic histories and genetic diversity of western North American tree species: implications for climate change
DownloadFall 2013
Over the last two million years, the evolution of North American tree species, subspecies, and genetic varieties has taken place in a constantly changing landscape often dominated by extensive ice sheets and restricted temperate climate environments. Here, I approximately reconstruct post-glacial...

Natural regeneration in the boreal forest: seedling establishment and success in western North American and European boreal forests
DownloadFall 2014
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...

Predicting conservation status of North American avian and mammalian scavengers: Implications of geography, life history, behaviour and human disturbance
DownloadFall 2011
Conservation risk is spatially and taxonomically variable, affected by both biological (intrinsic) and environmental (extrinsic) factors. To better understand this variability, I examined how intrinsic and extrinsic factors influenced sub-national patterns of conservation risk in North America...

Studies on the pollen-trapping fungal genus Retiarius: Taxonomy, phylogenetics, and metabolism with a special focus on western Canada
DownloadFall 2024
Fungi can obtain nutrients from a variety of sources, including some which capture and degrade pollen grains. Retiarius Olivier (Orbiliomycetes, Ascomycota) is an anamorphic hyphomycete that traps airborne pollen grains with aerial hyphae. Only four species, described from South Africa and...
