A study of the wet deposition of atmospheric pollutants in northeastern Alberta was initiated by Alberta Environment and Atmospheric Environment Service in 1976. The objectives of this ongoing study are to determine changes in the input rate of atmospheric trace substances into sensitive...

On 2 October 2007, we observed evidence of at least one brown bear (Ursus arctos) predating and caching broad whitefish (Coregonus nasus) at Pete’s Creek, a tributary of the Mackenzie River, Northwest Territories. While predation on whitefish by brown bears has been reported as traditional...

The boreal ecotype of woodland caribou (Rangifer tarandus caribou) is federally listed as Threatened due to population declines throughout its distribution. High mortality rates of neonate calves (≤ 4 weeks old) due to predation are a key demographic factor contributing to population declines...

The impact of parasites on hosts is invariably negative when considered in isolation, but may be complex and unexpected in nature. For example, if parasites make hosts less desirable to predators then gains from reduced predation may offset direct costs of being parasitized. We explore these...

Background: Tyrannosaurus rex was one of the largest terrestrial carnivores of all time, and consequently its ecology and diet have been the focus of much discussion. However, there is little direct evidence of diet or feeding habits in this species. Methodology/Principal Findings: Examination...

Waterflooding is one enhanced oil recovery process used in heavy oil reservoirs such as at Cold Lake in North-Eastern Alberta. However, little has been published in terms of imaging heavy oil waterfloods, mainly due to the similar densities of water and heavy oil, which makes it difficult to...

Worldwide, forest pathogens are a major cause of forest disturbances and can impact economic revenues and endanger host species and their ecosystems. Genomics represents one of the most promising avenues to better understand and prevent forest disease epidemics. Pathogen genome characterization...
