Polychlorinated Dibenzodioxins, Dibenzofurans and Non-ortho Substituted Polychlorinated Biphenyls in Caribou (Rangifer tarandus) from the Canadian Arctic
Resource
The presence of contaminants in the Arctic environment has raised concerns regarding levels in wildlife and possible effects on the health of wildlife populations. In addition, contaminants in wild...
Population Dynamics of Caribou Shaped by Glacial Cycles Before the Last Glacial Maximum
Resource
Pleistocene glacial cycles influenced the diversification of high- latitude wildlife species through recurrent periods of range contraction, isolation, divergence, and expansion from refugia and...
Population Ecology of Caribou Populations Without Predators: Southampton and Coats Island Herds
Resource
This paper is a review of the ecology of two caribou populations inhabiting predator-free northern islands, Coats and Southampton Island. Findings are analyzed in light of the hypothesis that in...
Progress Report on the Conservation and Recovery of Boreal Caribou (Rangifer tarandus caribou) in the Northwest Territories (2017-2021)
Resource
This document is a report on progress towards the conservation and recovery of boreal caribou in the Northwest Territories (NWT) from 2017 to 2021. This report meets the legislative requirement for a...
Public invited to comment on proposed re-listing of Peary and Boreal caribou as threatened in the Northwest Territories
News
Organization
The Northwest Territories Species at Risk Secretariat is accepting feedback on the proposed re-listing of Peary and Boreal caribou as threatened on the NWT List of Species at Risk. Comments on the...
Recent Climate Change has Driven Divergent Hydrological Shifts in High-latitude Peatlands
Resource
High-latitude peatlands are changing rapidly in response to climate change, including permafrost thaw. Here, we reconstruct hydrological conditions since the seventeenth century using testate amoeba...
Recovery Strategy for Barren-Ground Caribou in the Northwest Territories
Resource
This 70-page recovery strategy for barren-gound caribou in the Northwest Territories lays out plans to help the eight herds covered by the strategy. The strategy was required by the NWT Species at...
Recovery Strategy for the Boreal Caribou (Rangifer tarandus caribou) in the Northwest Territories
Resource
The purpose of this recovery strategy is to provide an action-oriented planning tool that identifies how the conservation and recovery of boreal caribou ( Rangifer tarandus caribou, woodland caribou...
Satellite Collaring Barren Ground Caribou
Resource
A 2-page fact sheet from the Government of the Northwest Territories explaining the use of radio collars on caribou. Related herds: Beverly and Qamanirjuaq , Bathurst, Bluenose West, Bluenose East...
Seasonal Patterns in Nutritional Condition of Caribou (Rangifer tarandus) in the Southern Northwest Territories and Northeastern British Columbia, Canada
Resource
Study sampled three measures of nutritional condition of adult female caribou, evaluated the effect of calf-rearing on condition and developed an annual profile of nutritional condition.
Setting a Foundation for Indigenous Knowledge Systems-guided Boreal Caribou (tǫdzı) Conservation Planning in the Western Boreal Region of Canada: A Systematic Map Protocol
Resource
Abstract In recent years, researchers have increasingly recognized the need to bridge Western and Indigenous knowledge systems to strengthen research in wildlife conservation. Historically, this arena...
Spatial and Temporal Variation in Forest Transpiration Across a Forested Boreal Peatland Complex
Resource
Transpiration is a globally important component of evapotranspiration. Careful upscaling of transpiration from point measurements is thus crucial for quantifying water and energy fluxes. In spatially...
State-dependent Foraging by Caribou With Different Nutritional Requirements
Resource
A 14-page academic paper that examines the connection between the physiological state of caribou and how they feed. The paper says, "Foraging time by caribou was partially state-dependent...
Status of Porcupine Caribou and Barren-ground Caribou in the NWT
Resource
A lengthy NWT government Species at Risk assessment of barren-ground caribou and Porcupine caribou. It classifies the Porcupine caribou as “not at risk” in the NWT, and the other herds as “threatened”...
Tactical Departures and Strategic Arrivals: Divergent Effects of Climate and Weather on Caribou Spring Migrations
Resource
A 2019 academic paper that looks at factors affecting caribou migration timing and speed. The paper concludes that later arrival at calving grounds might indicate that females are in worse condition...
The Direct and Habitat-mediated Influence of Climate on the Biogeography of Boreal Caribou in Canada
Resource
Effective species conservation efforts require insight into whether a species’ extent of occurrence may shift due to changing climate, habitat loss, or both. The extent of occurrence of the threatened...
The Essential Carbon Service Provided by Northern Peatlands
Resource
Northern peatlands have cooled the global climate by accumulating large quantities of soil carbon (C) over thousands of years. Maintaining the C sink function of these peatlands and their immense long...
