Climate-informed Forecasts Reveal Dramatic Local Habitat Shifts and Population Uncertainty for Northern Boreal Caribou
Resource
Most research on boreal populations of Woodland caribou ( Rangifer tarandus caribou) has been conducted in areas of high anthropogenic disturbance. However, a large portion of the species’ range...
Comparing Deep Learning and Shallow Learning for Large-Scale Wetland Classification in Alberta, Canada
Resource
Developed two wetland inventory style products for a large (397,958 km2) area in the Boreal Forest region of Alberta, Canada, using Sentinel-1, Sentinel-2, and ALOS DEM data
Comparing Landscape Partitioning Approaches to Protect Wildlife Habitat in Managed Forests
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...
Conference Program - 17th North American Caribou Workshop 2018
Resource
This conference program provides details about the 17 North American Caribou Workshop. It contains the agenda and abstracts for all presentations. Scientific and Indigenous Knowledge have well...
Conservation Agreement on the Conservation of Woodland Caribou of the Boreal Population ("Boreal Caribou") in Labrador
Resource
SARA SECTION 11 (S11) CONSERVATION AGREEMENT - labrador The overarching goal of this Agreement is to articulate how the Parties will collaboratively support the recovery of boreal caribou in Labrador.
Contaminants in Two West Greenland Caribou Populations
Resource
Two caribou populations in West Greenland were sampled and the kidneys, liver and muscle analyzed for contaminants, including aluminum, arsenic, cadmium, copper, lead, mercury, selenium and zinc...
Context-dependent Group Size: Effects of Population Density, Habitat, and Season
Resource
Group size can vary in relation to population density, habitat, and season. Habitat and season may also interact with population density and affect group size through varying foraging benefits of...
Continental Synchrony and Local Responses: Climatic Effects on Spatiotemporal Patterns of Calving in a Social Ungulate
Resource
Warming temperatures and advancing spring are affecting annual snow and ice cycles, as well as plant phenology, across the Arctic and boreal regions. These changes may be linked to observed population...
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...
Coyote (Canis latrans) Diet and Spatial Co-occurrence with Woodland Caribou (Rangifer tarandus caribou)
Resource
The interplay of predator encounters and antipredator responses is an integral part of understanding predator–prey interactions and spatial co-occurrence and avoidance can elucidate these interactions...
Decision-support Tools to Assess Cumulative Effects on the Cape Bathurst, Tuktoyaktuk Peninsula, Bluenose-West, and Bluenose-East Herds of Barren-ground Caribou – Project Summary Report
Resource
This report summarizes a project whose purpose was to collaboratively develop decision-support tools that will help northern decision-makers review, explore, and learn about the cumulative effects of...
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...
Delaying Conservation Actions Matters for Species Vulnerable to Climate Change
Resource
Abstract Climate change vulnerability assessments are commonly used to identify species or populations at risk from global climate change, but few translate impact assessments to climate change...
Development of a Model Ensemble to Predict Peary Caribou Populations in the Canadian Arctic Archipelago
Resource
Study of the strength and nature of the relationships of snow density and vegetation with Peary caribou populations using a spatially explicit modelling framework.
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...
Divergent Estimates of Herd‐wide Caribou Calf Survival: Ecological Factors and Methodological Biases
Resource
Abstract Population monitoring is a critical part of effective wildlife management, but methods are prone to biases that can hinder our ability to accurately track changes in populations through time...
