We used mark-recapture methods to estimate the number of Parnssius smintheus (Papilionidae) butterflies moving among 20 alpine meadows separated by varying amounts of forest along the east slope of the Rocky Mountains in Alberta, Canada. We combined generalized additive models and generalized...
Are boreal birds resilient to forest fragmentation? An experimental study of short-term community responsesDownload
Abstract: We studied the effect of habitat fragmentation on the richness, diversity, turnover, and abundance of bleeding bird communities in old, boreal mixed-wood forest by creating isolated and connected forest fragments of 1, 10, 40, and 100 ha. Connected fragments were linked by 100 m wide...
The conservation of large mammals such as Asian elephant (Elephas maximus) and tiger (Panthera tigris) requires management of core reserves, as well as habitat and connectivity across multiple-use areas. These charismatic species may also help catalyze conservation investments that may benefit...
This facilitator handbook is a companion document to the workbook entitled "Digital Content and Connectivity with Gwich’in Contexts: Workbook". It was developed as a joint pilot project between the Gwich’in Tribal Council (GTC) and the University of Alberta’s Faculty of Extension to explore...
This workbook was developed for a joint pilot workshop project between the Gwich’in Tribal Council (GTC) and the University of Alberta’s Faculty of Extension to explore digital literacy in the North. The workshop involved discussion of concepts related to digital content (digitization, archiving...
While many studies have evaluated wildlife passage effectiveness, few have explored how accurately passage activity can be modelled. I created a habitat suitability index (HSI) model for American mink (Neovison vison) using Geographic Information Systems with 1...

The mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins), a major pine forest pest native to western North America, has extended its range north and eastward during an ongoing outbreak. Determining how the MPB has expanded its range to breach putative barriers, whether physical...
Intermediation and Governance of Digital Flows: Canadian Internet Service Providers as Instruments of Public PolicyDownload
The internet has often had a disintermediating effect, 'disrupting' and circumventing traditional middlemen and gatekeepers. This dissertation examines the related trend of intermediation, or the ascendance of new internet intermediaries and their growing significance in our lives. Among these...
Landscape Ecology of Mule Deer (Odocoileus hemionus) and White-tailed Deer (O. virginianus) with Implications for Chronic Wasting DiseaseDownload
Chronic wasting disease (CWD) is a fatal prion disease of cervids that continues to spread into new regions of Canada despite containment efforts. I examine the importance of landscape connectivity using circuit theory and source/sink habitats that are based on selection, survival and...
Migration and survival of Parnassius smintheus: Detecting effects of habitat for individual butterfliesDownload
We examined the migration and survival of the butterfly Parnassius smintheus in a heterogeneous landscape consisting of 21 habitat patches imbedded in a matrix of meadow and forest habitat. We modified an existing mark-release-recapture model to account for multiple habitat types and fit the...
