Offsetting approved harmful anthropogenic impacts in the 21st century – Insights into global offsetting practices, habitat banking as an alternative offsetting mechanism and application of habitat enhancement in northern boreal lake systems
DownloadFall 2022
Land-use change via human development is a major driver of biodiversity and habitat area loss and ecosystem function impairment. To reduce these impacts, billions of dollars are spent on environmental offsets, aimed to compensate for authorized negative impacts. Studies evaluating offset project...

The Rocky Mountain apollo butterfly, Parnassius smintheus, and its host-plant Sedum lanceolatum, are endemic to open alpine meadows threatened by the encroachment of trees. I explore variability in interactions between P. smintheus and S. lanceolatum relative to the treeline-delimited meadow...

Polar bears (Ursus maritimus) enter a period of intensified feeding in the spring, which allows for the accumulation of energy stores critical to surviving the open water season. Study on polar bear predation has been limited by sample size and spatial extent, and hypotheses on the demographic...

Glass sponge reefs are globally unique ecosystems on Canada’s western continental shelf that are susceptible to harm from fishing (e.g., bottom-contact trawling). In 2017, a marine protected area (MPA) was created to protect four of these reefs in Hecate Strait and Queen Charlotte Sound. Three...

Festuca hallii (plains rough fescue), a late-seral bunchgrass and long-lived perennial, is difficult to restore once disturbed. Once dominant in grasslands throughout central Alberta, F. hallii now occurs in remnants, a result of agricultural and residential development, and oil and gas...

Saproxylic Beetles (Coleoptera) Associated With Aspen Deadwood in Broad-Leaved Boreal Mixedwood Stands
DownloadFall 2012
I assessed deadwood-associated (i.e., ‘saproxylic’) beetles (Coleoptera) along a decay gradient of trembling aspen in mature deciduous stands of the boreal mixedwood forest in NW Alberta. Various collection methods were employed to sample saproxylic beetle species. Assemblages differed between...

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,...

The choices animals make such as what habitat to use or where to live are influenced by individual behavior and life history traits. Gaining insight on space use patterns and habitat selection of a species can help wildlife managers in understanding social dynamics, population size and density,...

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...
