Use of Indices of Biological Integrity (IBIs) to assess wetland health in dry and wet conditions
DownloadSpring 2012
Indices of Biological Integrity (IBIs) estimate the biological condition of an ecosystem by measuring biological metrics that predict underlying environmental stress. I evaluated the use of IBIs developed from 5 biotic communities at 81 semi-permanent/permanent natural and constructed wetlands. ...

Understanding how populations are structured and how they use natural and anthropogenic spaces is essential for effective wildlife management. A total of 510 barren-ground (Rangifer tarandus groenlandicus), 176 boreal (R. t. caribou), 11 mountain woodland (R. t. caribou), and 39 island (R. t....

Using "omics" approaches to study anaerobic hydrocarbon biodegradation by microbes indigenous to oil sands tailings ponds
DownloadSpring 2014
In oil sands tailings ponds, methanogenesis is driven in part by the degradation of hydrocarbons in residual solvents used as a diluent during bitumen extraction, such as naphtha. Alkanes constitute a large proportion of these unrecovered hydrocarbons in mature fine tailings (MFT). Methanogenic...

Accurate assessment of how animals distribute themselves across the landscape is an essential component of ecological research. Ecologists often conduct surveys to subsample a representative portion of an area of interest and extrapolate their findings to a larger region. Acoustic surveys are...

Fall 2018
Anthropogenic disturbance is known to have negative population consequences and alter animal behaviour, and a growing body of research on the effects of anthropogenic noise is finding similar negative impacts on wildlife. Noise in natural environments can mask important acoustic signals used for...

Using spatial autocorrelation to quantify the effects of sea ice fragmentation on polar bear movement in Hudson Bay
DownloadSpring 2020
Habitat fragmentation occurs when continuous habitat gets broken up as a result of ecosystem change. While commonly studied in terrestrial ecosystems, Arctic sea ice ecosystems also experience fragmentation, but are rarely studied in this context. Most fragmentation analyses are conducted using...

Although typically referred to as a generalist species, individual prey specialization has been documented in cougars (Puma concolor). This behaviour has the potential to limit and regulate ungulate dynamics, particularly in cases where ungulates exist in small or isolated populations. Cougars...
