Spring 2014
The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. Yet this relationship lacks both consensus in theoretical expectations and consistency in observed empirical patterns. I present one of the largest extent studies...

Alpine glaciers have been retreating since the Little Ice Age, leading to exposure of foreland soils. Microorganisms are the primary below ground biological influence on nutrient cycling in recently deglaciated soil and are linked to down valley vegetation colonization. Previous studies...

Leafrollers moths are one of the most ecologically and economically important groups of herbivorous insects. These Lepidoptera are an ideal model for exploring the drivers that modulate the processes of diversification over time. This thesis analyzes the evolution of Choristoneura Lederer, a well...

Microbial communities are responsible for biogeochemical processes in soils such as nutrient cycling and organic matter formation, which are essential to the establishment of vegetation and ecosystem sustainability. Phospholipid fatty acid analysis, microbial respiration and enzymatic activities...

The Biogeography of Ground Beetles (Coleoptera: Carabidae) on the Islands of Lac la Ronge, Saskatchewan, Canada
DownloadFall 2015
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...

Dromaeosaurids were small to medium sized theropod dinosaurs that diversified during the Late Cretaceous, reaching a near cosmopolitan distribution. They were diverse in morphology from the small four-winged gliders of Microraptorinae, to the bear-sized giant ‘raptors’ like Achillobator or...

Montane grasslands play a key role in supporting wintering elk in the Rocky Mountains of Alberta. To document change in grassland extent and patch sizes, I analyzed repeat aerial photography at 4 sites in the upper Red Deer River drainage between 1952 and 2003. Excluding the Ya Ha Tinda,...

In Southwestern Yukon, alpine ice patches are rapidly retreating with climate warming. Ice patch forelands form unique alpine wetlands, creating critical habitats for diverse flora and fauna over millennia. A major component of the ice patch flora are bryophytes, which are critical to alpine...
