Fall 2017
Multiple novel and rapidly changing environmental factors (i.e. anthropogenic stressors) are increasingly affecting ecological communities, and their functional roles in ecosystems. Consequently, freshwater biodiversity has declined worldwide; however, the functional impacts of this loss should...

Systematics and diversity of Ichneumonidae, with an emphasis on the taxonomically neglected genus Ophion Fabricius
DownloadFall 2013
Ichneumonidae are the most species-rich family of parasitic Hymenoptera and are important for regulating populations of other arthropods. However, with an estimated 75% of species undescribed, we lack fundamental information about their taxonomy, ecology, and distributions. Using two different...

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...

The Ecology, Neoichnology and Sedimentology of Siliciclastic Hardground Communities: Implications for Trypanites Assemblages in the Rock Record
DownloadFall 2014
The paleoecology of rocky substrates in the rock record is commonly interpreted based on ichnology (the Trypanites ichnofacies) and is frequently associated with a biotic assemblage with low diversity. However, analyses of two modern, siliclastic, intertidal hardground community at Lion Rock,...

Anthropogenic noise is increasingly widespread as human development continues. Noise can negatively affect humans and wildlife, but the most deleterious effects are incurred by species that rely on vocal communication for mating, territory defence, and other vital functions. Songbirds are...

Fall 2023
Global change is altering ecological communities and the food webs they support, reducing food web persistence. While a variety of features likely impact the dynamics of perturbed food webs, the relative importance of intrinsic factors (i.e. characteristics of the food web itself) and extrinsic...

The Influence of Land-cover Type and Vegetation on Nocturnal Foraging Activities and Vertebrate Prey Acquisition by Burrowing Owls (Athene cunicularia).
DownloadFall 2012
Studies of habitat selection by foraging animals assume patterns of animal presence correlate with successful foraging, without explicit evidence this is valid. I used GPS dataloggers and digital video recorders to determine precise locations where nocturnally foraging Burrowing Owls captured...

Using under-road tunnels to protect a declining population of long-toed salamanders (Ambystoma macrodactylum) in Waterton Lakes National Park
DownloadFall 2010
I investigated the value of under-road tunnels as a conservation strategy to protect a long-toed salamander population, in south-west Alberta, whose overwintering sites and breeding habitat (Linnet Lake) are separated by a road. I conducted a mark-recapture study from 2008-2009, capturing...

Spring 2013
Woodland caribou (Rangifer tarandus caribou) populations are threatened across Canada. Recovery plans are being implemented to address conservation priorities using the best available knowledge. I used animal location data to evaluate sampling requirements for estimating caribou population...

Fall 2009
Woodland caribou population declines in west-central Alberta precipitated a wolfcontrol. This program to protect caribou could be compromised if (1) there are strong public pressures against helicopter gunning and strychnine poisoning of wolves and/or (2) other predators compensate to kill...
