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...

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...

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...

The impact of recreational activities on an alpine vascular plant community in the Canadian Rockies
DownloadFall 2010
Alpine tundra is notorious for its fragility and slow recovery following disturbance. Tourism is increasing in alpine areas, creating the need to improve our understanding of the impacts of recreation in these ecosystems. This study examined the impacts of hiking and off-highway vehicle use on...

Fall 2010
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...

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...

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...

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...

Fall 2018
Benthic marine habitats in Canada have been well-sampled since the annual groundfish survey commenced in 1970. However, trawl surveys cover only non-rocky sediments and many species collected are not identified to lower taxa, leaving large gaps in our understanding of benthic diversity. Sponges...

Semiochemical-based mass trapping of the apple clearwing moth (Synanthedon myopaeformis (Borkhausen)) (Lepidoptera: Sesiidae)
DownloadFall 2011
Semiochemical-based mass trapping was tested against the apple clearwing moth (Synanthedon myopaeformis (Borkhausen)), an invasive apple pest in British Columbia. Two yellow traps baited with apple clearwing moth sex pheromone, (Z,Z)-3,13 octadecadienyl acetate, and Concord grape juice,...
