Identification of halogenated polycyclic aromatic hydrocarbons in biological...
Highlights • GC-HR-TOF/MS method was used to identify halogenated compounds in biota. • Three halogenated compounds were positively identified in biological samples. • These... -
Forestry and conspecifics influence Canada Warbler (Cardellina canadensis)...
The Canada Warbler (Cardellina canadensis) is a threatened species in Canada due to an annual decline of ∼3% over the last 50 yr. Some studies suggest that Canada Warblers... -
Foliage Chemistry of Pinus Banksiana in the Athabasca Oil Sands Region,...
Industrial emissions in the Athabasca Oil Sands Region (AOSR), Alberta, Canada, have caused concerns about the effect of oil sands operations on the surrounding terrestrial... -
First full annual cycle tracking of a declining aerial insectivorous bird,...
Over one third of North American bird species are in decline, and for many species, we still lack fundamental biogeographic information such as migration routes and nonbreeding... -
Exploring the complexity of oil sands process-affected water by high...
Approximately 1 billion m3 of oil sands process-affected water (OSPW) is currently stored in tailings ponds in Northern Alberta, Canada. The dissolved organic compounds in OSPW... -
Experimentally derived detection distances from audio recordings and human...
Point counts are one of the most commonly used methods for assessing bird abundance. Autonomous recording units (ARUs) are increasingly being used as a replacement for human-... -
Evaluating time removal models for estimating availability of boreal birds...
We used conventional and finite mixture removal models with and without time-varying covariates to evaluate availability given presence for 152 bird species using data from... -
Enhanced characterization of oil sands acid-extractable organics fractions...
The open pit oil sands mining operations north of Fort McMurray, Alberta, Canada, are accumulating tailings waste at a rate approximately equal to 4.9 million m3/d. Naphthenic... -
Effects of Extraction pH on the Fourier Transform Ion Cyclotron Resonance...
A comparison of the acidic and basic extracts of oil sands process water (OSPW) was performed using positive- and negative-ion electrospray ionization (ESI) and atmospheric... -
Development of Differential Absorption Lidar (DIAL) for Detection of CO2,...
Rapid expansion of the oil and gas industry in Alberta, including the oil sands, has challenged the Alberta Government to keep pace in its efforts to monitor and mitigate the... -
Delineating and identifying long-term changes in the whooping crane (Grus...

A hydrologic assessment of a saline-spring fen in the Athabasca oil sands...
Canada's post-mined oil sands will have a higher concentration of salts compared with freshwater peatlands that dominate the landscape. While rare, naturally occurring saline... -
Advances in mass spectrometric characterization of naphthenic acids fraction...
There has been a recent surge in the development of mass spectrometric methods for detailed characterization of naphthenic acid fraction compounds (all CcHhNnOoSs, species,... -
Airborne Lidar Measurements of Aerosol and Ozone above the Canadian Oil Sands Region
Aircraft-based lidar measurements of atmospheric aerosol and ozone were conducted to study air pollution from the oil sands extraction industry in northern Alberta. Significant...
