Ecosystem sensitivity to variation in precipitation and defoliation across grasslands of Alberta
DownloadSpring 2022
Climate models project a greater likelihood of increases in precipitation variability and droughts over the Great Plains of North America. Drought’s interactions with other co-occurring factors, such as grazing, can lead to substantial and long-lasting changes to ecosystem goods and services. In...

Effect of climate change on permafrost microbiome at the Pleistocene-Holocene and Holocene-Anthropocene transitions
DownloadSpring 2021
Understanding past and future responses of Arctic soil microbes to climate change is critical to an understanding of ecosystem function and climate change feedbacks; the goal of my thesis was to obtain a clearer understanding of these feedbacks. The remnants of the Pleistocene and early Holocene...

Effect of fluctuating temperature and propagule flow on invasibility of global marine habitats and species distribution
DownloadFall 2013
Invasive colonizers propagated through human-mediated vectors are bio-homogenizing the world’s oceans and impacting the ecological structures and functions. Where do they come from, and where do they go? What bio-physical mechanisms drive them to do what they do? Can we control the human-mediated...

Effect of weather during development on cranial morphometrics of American marten (Martes americana)
DownloadSpring 2024
Globally, climate change is affecting species in a myriad of ways. Rapid morphological change has been proposed to be a consequence of climate change, but evidence is minimal. Furthermore, any such rapid morphological change is expected to be a phenotypic response rather than evolutionary....

Effects of acanthocephalan parasites on colour and carotenoid quantities of their intermediate host Gammarus lacustris in the context of variable lake productivity
DownloadFall 2010
I studied the effects of Polymorphus paradoxus Connell and Corner and Polymorphus marilis Van Cleave on colour and carotenoid quantities of their host amphipod Gammarus lacustris G.O. Sars in seven lakes in Alberta, Canada, that differed in productivity. Polymorphus marilis induced ‘pigmentation...
