Conservation of Caribou (Rangifer tarandus) in Canada: An Uncertain Future
Resource
Caribou (Rangifer tarandus (L., 1758)) play a central role in the ecology and culture of much of Canada, where they were once the most abundant cervid. Most populations are currently declining, and...
Conservation of Future Boreal Forest Bird Communities Considering Lags in Vegetation Response to Climate Change: A Modified Refugia Approach
Resource
For some boreal songbirds, limits to forest growth and succession may result in dramatic reductions in suitable habitat over the next century.
Conserving Alberta’s Biodiversity Under Climate Change: A Review and Analysis of Adaptation Measures
Resource
Although ecological transitions are expected to be widespread, under even the least-change climate scenario, ecological change is not synonymous with the loss of biodiversity.
Controls on Methylmercury Concentrations in Lakes and Streams of Peatland-Rich Catchments Along a 1700 km Permafrost Gradient
Resource
Permafrost thaw may increase the production of neurotoxic methylmercury (MeHg) in northern peatlands, but the downstream delivery of MeHg is uncertain. We quantified total mercury (THg) and MeHg...
Creating a Knowledge Platform for the Reclamation and Restoration Ecology Community: Expanding the OSRIN Model Beyond the Oil Sands
Resource
One of the core mandates for the Oil Sands Research and Information Network (OSRIN) was to enhance access to oil sands environmental management information. With OSRIN’s mandate ending December 31...
Cumulative Effects and Boreal Woodland Caribou: How Bow-Tie Risk Analysis Addresses a Critical Issue in Canada's Forested Landscapes
Resource
Boreal caribou (Woodland Caribou, boreal population; Rangifer tarandus caribou) is a prominent mammal at the heart of a decades-long conflict between a growing resource sector and the associated risks...
Deeper Soil Salvaging Depths Produce Greater Cover of Native Plants than Shallow Salvage Depths on a Reclaimed Coal Mine Site
Resource
The deeper soil salvage depth (40 cm) was better than the shallow salvage depth (15 cm) at establishing a forest understory plant community characteristic of the boreal forest.
Deer Are Expanding North, and That's Not Good For Caribou
News
Organization
Over the past century, white-tailed deer have greatly expanded their range in North America, explains Melanie Dickie, a doctoral student with UBC Okanagan’s Wildlife Restoration Ecology Lab. In the...
Demand for Nonprovisioning Ecosystem Services as a Driver of Change in the Canadian Boreal Zone
Resource
The Canadian boreal zone provides ecosystem services from local to global scales. Either directly or indirectly, demands for these services have and will continue to serve as drivers of change in the...
Demographic Responses of a Threatened, Low-density Ungulate to Annual Variation in Meteorological and Phenological Conditions
Resource
Study highlights the increased relevance of recovery actions when adverse climatic conditions are likely to negatively affect caribou demography.
Demographic Responses of Nearly Extirpated Endangered Mountain Caribou to Recovery Actions in Central British Columbia
Resource
Recovering endangered species is a difficult and often controversial task that challenges status-quo land uses. Southern Mountain caribou are a threatened ecotype of caribou that historically ranged...
Deposition of Sulphur and its Influence on Soils in the AOSERP Study Area
Resource
Several field investigations were carried out to determine the amounts of sulphur deposited in rain, in rain washing off trees, and by direct absorption of SO2 by soil
Determining Sustainable Levels of Cumulative Effects for Boreal Caribou
Resource
This resource is available on an external database and may require a paid subscription to access it. It is included on the CCLM to support our goal of capturing and sharing the breadth of all...
Development of a Toxin-Mediated Predator-Prey Model Applicable to Aquatic Environments in the Athabasca Oil Sands Region
Resource
Previous work has considered the effect of a toxin on the population dynamics of a single trophic level, such as fish, we focus on the impacts of toxins on the population dynamics of aquatic food webs
Development of an Extraction Method for Estimating Phytoaccessible Fractions of Bromacil and Tebuthiuron
Resource
Bromacil and tebuthiuron are herbicides used from the 1960s to 1990s on industrial sites to control vegetation. Approximately 61,750 sites are considered contaminated when comparing total herbicide...
Dewatering Fine Tails by Evaporation: A Mathematical Modelling Approach
Resource
A one dimensional approach was used to model the evaporation process from fine tails. Understanding the complex interactions among the solids, water and external atmospheric demand is required
