Afforestation and stand age affected soil respiration and net ecosystem productivity in hybrid poplar plantations in central Alberta, Canada
DownloadFall 2010
Afforestation and stand development can significantly affect soil respiration and net ecosystem productivity (NEP). I studied 1) the effects of afforestation on NEP by comparing cropland previously planted to barley (on a barley-barley-alfalfa-alfalfa-alfalfa rotation) and that converted to a...

Are managed honey bees (Apis mellifera) altering native pollinator diversity, or their interactions with plants in Western Canadian grasslands?
DownloadSpring 2021
The grasslands region of southern Alberta, Canada, is dominated by agricultural activity, and approximately 75% of native grasslands have been lost to development. Honey bees (Apis mellifera) were introduced about a century ago, and today they are used to facilitate the pollination of crops; in...

Assessing the effects of non-native salmonids on Bull Trout (Salvelinus confluentus) in Alberta’s Rocky Mountain Foothills
DownloadFall 2022
The rapid decline in global biodiversity threatens the natural resources, food security, health, and livelihoods of current and future generations. Anthropogenic activities, including the introduction of non-native species, habitat fragmentation and alteration, and resource extraction, have...

Assisted migration to address climate change: recommendations for reforestation in western Canada
DownloadFall 2011
A changing climate is the largest threat to forest productivity in western Canada and to the ability of forested landscapes to provide ecological and economic services, both now and in the future. As climate changes, locally adapted tree populations become mismatched with local conditions,...

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...

Climate change, adaptive capacity and new land innovations implemented by local farmers and indigenous people in Puerto Carreno, Colombia
DownloadFall 2012
A case study research was conducted in the city of Puerto Carreño, Colombia to assess adaptive capacity for the Farmers’ community and indigenous people to face climate change. Some of these inhabitants understand these changes in the weather as natural processes, others as climate change. The...

Community ecology of ants (Hymenoptera: Formicidae) in the central sand hills of Alberta, and a key to the ants of Alberta.
DownloadFall 2012
In this study I examined ant biodiversity in Alberta. Over a two-year period, 41,791 ants were captured in pitfall traps on five sand hills in central Alberta and one adjacent aspen parkland community. Using additional collections, I produced a key to the 92 species of ants known from Alberta,...

Grasslands cover a quarter of the planet’s terrestrial surface and constitute 70% of the world’s agricultural land area. Grasslands provide clean water, facilitate effective nutrient cycling, and provide necessary habitat and forage for livestock and wildlife. In addition, grasslands have the...

Bioclimate envelope models are widely used to project potential species habitat under changing climate. Conceptually, these models are also well suited to match natural resource management practices to new climatic realities, for example by guiding species choice in reforestation programs....

Arsenic (As) concentration above the Health Canada and WHO drinking water guidelines of 10 µg L-1 in the Cold Lake area, Alberta is an issue of concern for environmental and human health. The source of groundwater As is ambiguous. This study was initiated to characterize the surficial deposits...
