A Before-After Dose-Response (BADR) Terrestrial Biological Monitoring Framework for the Oil Sands
Resource
One of the theme areas monitored within the OSM program is terrestrial biodiversity, known programmatically as Terrestrial Biological Monitoring (TBM). Biodiversity refers to the diversity of wild...
A Survey of Baseline Levels of Contaminants in Aquatic Biota of the AOSERP Study Area
Resource
Analyses are given for up to 12 metals and 4 pesticides with PCBs, of aquatic environment from 15 sites along or near the Athabasca River from Fort McMurray north to the confluence of the Peace River
Ability of Lotic Micro-organisms and Macrobenthos to Degrade and Assimilate Bitumen
Resource
Colonization of limestone bricks and bitumen coated limestone bricks by benthic river organisms was followed over time.
Amended Recovery Strategy for the Woodland Caribou (Rangifer tarandus caribou), Boreal Population, in Canada [Proposed]
Resource
The recovery strategy sets the strategic direction to arrest or reverse the decline of the species, including identification of critical habitat to the extent possible. It provides all Canadians with...
An Intensive Study of the Fish Fauna of the Muskeg River Watershed of Northeastern Alberta
Resource
Study of the fish fauna in the Muskeg River commenced in 1976 with the general objective of describing the baseline states of this resource in the watershed and providing a quantitative estimate
An Intensive Study of the Fish Fauna of the Steepbank River Watershed of Northeastern Alberta
Resource
The resident fish fauna of the Steepbank River consists largely of pearl dace, brook stickleback, lake chub, longnose dace and slimy sculpin.
Aquatic Biological Investigations of the Muskeg River Watershed
Resource
The epilithic microbial and micro-invertebrate communities under conditions of light and shade were studied from April to November 1978
Audio Data Compression Affects Acoustic Indices and Reduces Detections of Birds by Human Listening and Automated Recognisers
Resource
Increasing popularity in passive acoustic monitoring and the ease with which researchers can accumulate large quantities of acoustic data has resulted in challenges for audio recording storage...
Automated Classification of Avian Vocal Activity Using Acoustic Indices in Regional and Heterogeneous Datasets
Resource
Acoustic indices combined with clustering and classification approaches have been increasingly used to automate identification of the presence of vocalizing taxa or acoustic events of interest. While...
Bioengineering Techniques for Revegetation of Riparian Areas at the Colomac Mine, NWT
Resource
Factors such as nutrient poor soils, harsh climate, remote locations, and high costs make revegetating disturbed areas in northern environments a challenge. We present a case study where novel...
Breeding Distribution and Behaviour of the White Pelican in the Athabasca Oil Sands Area.
Resource
Aerial surveys and ground investigations were conducted in the spring and summer months from 1975 to 1977 on a breeding population of White Pelicans (Pelecanus erythrorhynchos) in the Birch Mountains

Contribution of Rain Events to Surface Water Loading in 3 Watersheds in Canada’s Alberta Oil Sands Region
Resource
To evaluate the importance of rain events to these rivers, discharge and water quality sampling was conducted at river sites in this region. Two approaches were used to collect water quality samples:...
Contributions and Perspectives of Indigenous Peoples to the Study of Mercury in the Arctic
Resource
Arctic Indigenous Peoples are among the most exposed humans when it comes to foodborne mercury (Hg). In response, Hg monitoring and research have been on-going in the circumpolar Arctic since about...
Defining Habitat Restoration for Boreal Caribou in the Context of National Recovery: A Discussion Paper
Resource
With many boreal caribou population ranges across Canada in non-self sustaining condition, habitat restoration has become an increasing imperative for recovery of this species at risk. With decades...
Development of Soil Quality Criteria for Contaminated Site Remediation
Resource
There can be little argument that contaminants are now a ubiquitous presence in our environment. Though large-scale efforts to deal with contaminant issues have traditionally focused on water and air...
