A Map of Global Peatland Extent Created Using Machine Learning (Peat-ML)
Resource
Peatlands play an integral role in the global carbon and hydrologic cycles and make up 3% of the Earth’s total landscape. Despite their importance, there is a lack of accurate information on the...
Birth Date Determines Early Calf Survival in Migratory Caribou
Resource
Abstract The decline of most caribou ( Rangifer tarandus) populations underlines the need to understand the determinants of key demographic parameters. In migratory caribou, we have limited...
Caribou, Water, and Ice – Fine-scale Movements of a Migratory Arctic Ungulate in the Context of Climate Change
Resource
Background: Freshwater lakes and rivers of the Northern Hemisphere have been freezing increasingly later and thawing increasingly earlier during the last century. With reduced temporal periods during...
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...
Determinants of Migration Trajectory and Movement Rate in a Long-distance Terrestrial Mammal
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...
Improving Peary Caribou Presence Predictions in MaxEntUsing Spatialized Snow Simulations
Resource
In this article, the researchers 1) investigate whether a snow model adapted for the Antarctic (SNOWPACK) can produce snow simulations relevant to Canadian High Arctic conditions, and 2) test snow...
Large Stocks of Peatland Carbon and Nitrogen are Vulnerable to Permafrost Thaw
Resource
Northern peatlands have accumulated large stocks of organic carbon (C) and nitrogen (N), but their spatial distribution and vulnerability to climate warming remain uncertain. Here, we used machine...
Linear Disturbances Shift Boreal Peatland Plant Communities Toward Earlier Peak Greenness
Resource
Vast areas of boreal peatlands are impacted by linear disturbances known as seismic lines. Tree removal and ground disturbance alter vegetation communities and are expected to change ecosystem...
Loss of Connectivity Among Island-dwelling Peary Caribou Following Sea Ice Decline
Resource
Global warming threatens to reduce population connectivity for terrestrial wildlife through significant and rapid changes to sea ice. Using genetic fingerprinting, we contrasted extant connectivity in...
Modeled Production, Oxidation, and Transport Processes of Wetland Methane Emissions in Temperate, Boreal, and Arctic Regions
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...
The Boreal-Arctic Wetland and Lake Dataset
Resource
Here we present the Boreal–Arctic Wetland and Lake Dataset (BAWLD), a land cover dataset based on an expert assessment, extrapolated using random forest modelling from available spatial datasets of...
The Third Generation of Pan-Canadian Wetland Map at 10 m Resolution Using Multisource Earth Observation Data on Cloud Computing Platform
Resource
Development of the Canadian Wetland Inventory Map (CWIM) has thus far proceeded over two generations, reporting the extent and location of bog, fen, swamp, marsh, and water wetlands across the country...
Using Camera Collars to Study Survival of Migratory Caribou Calves
Resource
