Biogeochemical Response to Vegetation and Hydrologic Change in an Alaskan Boreal Fen Ecosystem
Resource
Boreal peatlands store approximately one third of the earth’s terrestrial carbon, locked away in currently waterlogged and frozen conditions. Peatlands of boreal and arctic ecosystems are affected...
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...
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...
Peat Loss Collocates with a Threshold in Plant–Mycorrhizal Associations in Drained Peatlands Encroached by Trees
Resource
Drainage-induced encroachment by trees may have major effects on the carbon balance of northern peatlands, and responses of microbial communities are likely to play a central mechanistic role. We...
Sublethal Effects of Parasitism on Ruminants Can Have Cascading Consequences for Ecosystems
Resource
Parasitic infections are common, but how they shape ecosystem-level processes is understudied. Using a mathematical model and meta-analysis, we explored the potential for helminth parasites to trigger...
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
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...
Video - Managing Soil Carbon in Temperate & Boreal Ecosystems
Resource
This presentation discusses managing soil carbon in temperate and boreal ecosystems.
Video - Nutritional Mechanism Impairs Caribou Pregnancy in the Alberta Oil Sands
Resource
At the 14th North American Caribou Workshop held in September 2012, Jonah Keim presented results of research looking into the impact of nutrition on caribou in the Alberta oil sands region.
Where to Spend the Winter? The Role of Intraspecific Competition and Climate in Determining the Selection of Wintering Areas by Migratory Caribou
Resource
