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...

Application of manure from cattle fed with different diets affects soil properties and greenhouse gas emissions
DownloadSpring 2019
Cattle production contributes the largest portion of livestock agricultural greenhouse gas (GHG) emissions in Canada mostly in the form of methane (CH4). Efforts to reduce CH4 emissions have led to modification of diet composition for livestock, resulting in a corresponding change in manure...

Spatial and temporal stand dynamics of mature lodgepole pine forests of the Canadian Rocky Mountains
DownloadFall 2015
In forest ecosystems, structure and species composition change over time as a function of ageing and minor disturbances and it is important to understand these changes for predicting forest productivity and habitat suitability for other plant and animal biota. Disturbances play a major role in...

Arsenic is a highly toxic and ubiquitous element. To this day, millions of people are exposed to arsenic contamination, which poses global health concerns. Phytoextraction performed with willows, a form of phytoremediation, is a promising means of cleaning up soils containing hazardous levels of...

The influence of the viable but non-culturable (VBNC) state on specific phenotypic traits of Escherichia coli O157:H7 as well as its transport behaviour in porous media was examined in this study. E.coli O157:H7 is a human pathogen capable of entering a VBNC state following exposure to sublethal...

Evaluating trade-offs: the effects of foraging, biting flies, and footing on wood bison (Bison bison athabascae) habitat use
DownloadSpring 2018
Understanding the distribution of forage is important in predicting the distribution, habitat use (behaviour), movements, and fitness-related traits of large, grazing ungulates. Although this bottom-up perspective provides a foundation for understanding habitat supply and thus nutrition, foraging...

Soil microbial communities in northern Alberta's boreal forest floors following resource extraction
DownloadFall 2017
Land disturbance linked to resource extraction in Alberta ranges in severity from full ecosystem removal during surface mining to more surficial disturbance during clearcut timber harvesting. Changes to these ecosystems affect the soil microbial community, and the health of boreal forests is...

Climate change implications for distribution, phenology and conservation of Olive-sided Flycatchers (Contopus cooperi) and Western Wood-Pewees (C. sordidulus) in northwestern North America
DownloadFall 2020
Northwestern North America is predicted to experience some of the world’s greatest human-caused climate change. Understanding the impacts of associated changes will be imperative to the conservation and management of northern-breeding birds. In particular, long distance migrants and aerial...
