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 Features, Forestry and Wolf Predation of Caribou and Other Prey in West Central Alberta
Resource
The primary goal of this research was to determine how human activities affect caribou population dynamics through modification of predator‐prey relationships. This knowledge can then be used to...
Linking Habitat, Populations and Policy for Caribou in The Face of Increasing Disturbance
Resource
This thesis analyzes female caribou resource selection response to fires and links disturbances to caribou behavior and demography throughout western Canada by relating resource selection responses to...
Managing Wolves (Canis Lupus) to Recover Threatened Woodland Caribou (Rangifer Tarandus Caribou) in Alberta
Resource
Across Canada, woodland caribou ( Rangifer tarandus caribou (Gmelin, 1788)) populations are declining because of human-induced changes to food webs that are resulting in apparent competition-induced...
Mechanized Tree Planting in Sweden and Finland: Current State and Key Factors for Future Growth
Resource
In Fennoscandia, mechanized tree planting is time-efficient and produces high-quality regeneration. However, because of low cost-efficiency, the mechanization of Fennoscandian tree planting has been...
Natural Regeneration on Seismic Lines Influences Movement Behaviour of Wolves and Grizzly Bears
Resource
Across the boreal forest of Canada, habitat disturbance is the ultimate cause of caribou ( Rangifer tarandus caribou) declines. Habitat restoration is a focus of caribou recovery efforts, with a goal...
Peatland Restoration Increases Water Storage and Attenuates Downstream Stormflow but Does Not Guarantee an Immediate Reversal of Long-term Ecohydrological Degradation
Resource
Peatland restoration is experiencing a global upsurge as a tool to protect and provide various ecosystem services. As the range of peatland types being restored diversifies, do previous findings...
Potential for Using Remote Sensing to Estimate Carbon Fluxes Across Northern Peatlands – A Review
Resource
Peatlands store large amounts of terrestrial carbon and any changes to their carbon balance could cause large changes in the greenhouse gas (GHG) balance of the Earth's atmosphere. There is still much...
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...
Resource Separation Analysis with Moose Indicates Threats to Caribou in Human Altered Landscapes
Resource
Species recovery is often impeded by inadequate knowledge on mechanisms of community interactions that cause and exacerbate species endangerment. Caribou and wild reindeer Rangifer tarandus are...
Satellite Determination of Peatland Water Table Temporal Dynamics by Localizing Representative Pixels of A SWIR-Based Moisture Index
Resource
The OPtical TRApezoid Model (OPTRAM) is a physically-based approach for remote soil moisture estimation. OPTRAM is based on the response of short-wave infrared (SWIR) reflectance to vegetation water...
Saving Endangered Species Using Adaptive Management
Resource
Adaptive management is a powerful means of learning about complex ecosystems, but is rarely used for recovering endangered species. Here, we demonstrate how it can benefit woodland caribou, which...
Scaling Up the Role of Predation in Caribou Declines in West-Central Alberta (Redwillow, Narraway, Redrock Prairie Creek, A la Pêche and Little Smoky Ranges)
Resource
Anthropogenic disturbances contribute to the way animals perceive and respond to their environment. These multiple disturbances can additionally act in non-independent ways to shape an animal’s...
