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...
Regional Variation in Green-up Timing Along a Caribou Migratory Corridor: Spatial Associations with Snowmelt and Temperature
Resource
Abstract Spring green-up in arctic and alpine systems is predominantly controlled by temperature and snowmelt timing preceding and during the growing season. Variation in the timing of green-up across...
Soluble Calcium and Sulphate Excesses Related to Stress in Pinus contorta on Peat Amendments of Reclaimed Landscapes in the Boreal Oil Sands Region
Resource
Results indicated a negative relationship among pine performance with increasing soluble calcium and available sulphate-S
Spatial and Temporal Changes in Seasonal Range Attributes in a Declining Barren-ground Caribou Herd
Resource
From 1996 to 2015 the Bathurst caribou herd has declined from approximately 349,000 to 20,000 animals. Aboriginal traditional knowledge (TK) has recently observed the later arrival of the herd below...
The Prado Wetlands: 24 Years of River Diversion Treatment Wetlands Reducing Nitrate and Phosphate while Increasing an Endangered Bird
Resource
Nitrate pollution of surface water from farms and urban runoff is widespread – impairing drinking water supplies, recreation, and wildlife habitat. The scale of the problem in rivers has overwhelmed...
Tools for Arctic Revegetation: What's in Your Toolbox?
Resource
Revegetation in arctic climates is a challenge for many reasons. There are two approaches to arctic revegetation: natural regeneration and active reclamation. Natural regeneration is an inexpensive...
Video - Wolves, Deer and Beaver: Implications of Prey Enrichment and Seasonal Prey Switching for Woodland Caribou Declines
Resource
At the 14th North American Caribou Workshop held in September 2012, Kyle Knopff presented research done researchers from the University of Alberta, University of Montana and Golder Associates Ltd.
Webinar - Caribou Habitat Restoration: A Trial in Northeastern Alberta
Resource
Woodland caribou (Rangifer tarandus caribou) are a threatened species federally and provincially in Alberta. Habitat restoration is critical to maintaining suitable habitat to support healthy...
Wolves, White-tailed Deer, and Beaver: Implications of Seasonal Prey Switching for Woodland Caribou Declines
Resource
Global warming and landscape changes in Alberta's bitumen sands have resulted in prey enrichment, which is changing the large mammal predator – prey system and causing declines in woodland caribou (...
Woodland Caribou "State of the Science" Backgrounder
Resource
Woodland caribou ( Rangifer tarandus caribou) are listed as a threatened species in Alberta and British Columbia and nationally; with the Central Mountain and Southern Mountain Populations listed as...
