A Decision Support Tool for Assessing Cumulative Effects on an Arctic Migratory Tundra Caribou Population
Resource
Using the caribou cumulative effects model, an existing decision support tool, we evaluate 6 alternative development scenarios, from no leasing to full leasing with standard mitigation conditions
A Regional-Scale Index for Assessing the Exposure of Drinking-Water Sources to Wildfires
Resource
Recent human-interface wildfires around the world have raised concerns regarding the reliability of freshwater supply flowing from severely burned watersheds. Degraded source water quality can often...
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...
Caribou Migration, Subsistence Hunting, and User Group Conflicts in Northwest Alaska: A Traditional Knowledge Perspective
Resource
Abstract Alaska Natives of northwest Alaska are highly dependent on barren-ground caribou ( Rangifer tarandus) for meeting their nutritional and cultural needs. The Alaska Native village of Noatak...
CircumArctic Collaboration to Monitor Caribou and Wild Reindeer
Resource
Caribou and wild reindeer ( Rangifer) are integral to ecology and Aboriginal lives and culture in circumArctic regions. Since reaching peak size in the 1990s, most herds have been declining, while...
Contrasts in Use and Perceptions of Biological Data for Caribou Management
Resource
Abstract Attitudes and perceptions toward caribou ( Rangifer tarandus) management practices held by users and managers of the Western Arctic Herd (WAH) in Alaska and the Beverly and Qamanirjuaq herds...
Do Beaver Ponds Increase Methane Emissions Along Arctic Tundra Streams?
Resource
Beaver engineering in the Arctic tundra induces hydrologic and geomorphic changes that are favorable to methane (CH 4) production. Beaver-mediated methane emissions are driven by inundation of...
Factors Contributing to the Cultural and Spatial Variability of Landscape Burning by Native Peoples of Interior Alaska
Resource
This article analyzes the geographical extent to which native peoples of Interior Alaska used fire to modify the landscape at the time of European contact. Although wildfire has been central to the...
Historical Landscape Use of Migratory Caribou: New Insights From Old Antlers
Resource
Accumulations of shed caribou antlers ( Rangifer tarandus) are valuable resources for expanding the temporal scope with which we evaluate seasonal landscape use of herds. Female caribou shed their...
Increasing Contributions of Peatlands to Boreal Evapotranspiration in a Warming Climate
Resource
The response of evapotranspiration (ET) to warming is of critical importance to the water and carbon cycle of the boreal biome, a mosaic of land cover types dominated by forests and peatlands. The...
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...
Nutrition Integrates Environmental Responses of Ungulates
Resource
1. Nutrition influences most aspects of animal ecology: juvenile growth rates and adult mass gain, body condition, probability of pregnancy, over-winter survival, timing of parturition, and neonatal...
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...
Population Structure and Hybridization of Alaskan Caribou and Reindeer: Integrating Genetics and Local Knowledge
Resource
Abstract Alaskan caribou ( Rangifer tarandus granti) are a valued game species and a key grazer in Alaska's terrestrial ecosystem. Caribou herds, defined by female fidelity to calving grounds, are...
Rapid Transformation of Tundra Ecosystems From Ice-wedge Degradation
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 Biophysical Climate Mitigation Potential of Boreal Peatlands During the Growing Season
Resource
Peatlands and forests cover large areas of the boreal biome and are critical for global climate regulation. They also regulate regional climate through heat and water vapour exchange with the...
