The use of rayon in 1920s and 1930s garments confronts conservators with new challenges: definitive fibre identification involves more than basic microscopy and treatment can be difficult with little available research on early rayon and its conservation. Rayon is expected to degrade similarly to...

Identifying seasonal Lake Sturgeon (Acipenser fulvescens) movement patterns and habitat selection in the South Saskatchewan River Basin
DownloadFall 2016
Lake Sturgeon (Acipenser fulvescens Rafinesque 1817) have experienced population declines throughout their range. In Alberta, low density age-class distributions, irregular recruitment, critically low spawning potential ratios and other factors led to a 2007 designation of “Threatened” for this...

Impacts of clear-cut harvesting on carabid beetle (Coleoptera: Carabidae) assemblages of aspen dominated forests in central Alberta
DownloadFall 2016
Disturbances, both natural and those related to human activity, reset succession in boreal ecosystems, and affect forest biodiversity. The link between forest harvesting and biodiversity is of considerable conservation concern. In this thesis, I investigate the impacts of clear-cut harvesting on...

Influence of forestry and conspecific attraction on habitat use and reproductive activity of the Canada warbler (Cardellina canadensis) in the western boreal forest: Implications for critical habitat identification
DownloadSpring 2017
Recovery strategies for species at risk are legally mandated in Canada and the Government of Canada must identify which habitat is important for a species and which activities result in its destruction. The Canada Warbler (Cardellina canadensis) has been designated as a threatened species in...
