Buried Wood Effects on Macronutrient Supply and Microbial Activity and Metabolic Potential in Different Oil Sands Reclamation Soils in Northern Alberta
Resource
Buried wood is an important yet understudied component of natural and anthropogenic soils. Nutrient immobilization as a response to wood addition during oil sands' reclamation may be a concern since...
Developing a Reclamation Costing Framework for the Athabasca Oil Sands
Resource
The Athabasca oil sands are a significant component of the economy in Alberta. However, they also represent a large environmental risk. At the end of mining operations, companies are expected to begin...
Effects of Elemental Sulfur on Soil pH and Growth of Saskatoon Berry (Amelanchier alnifolia) and Beaked Hazelnut (Corylus cornuta) Seedlings
Resource
The land disturbed by open-pit oil sands mining must be restored to support the survival and growth of native boreal plants. Because tailings sand and sodic shale overburden are commonly used as an...
Environmental and Management Drivers of Carbon Dioxide and Methane Emissions From Actively-Extracted Peatlands in Alberta, Canada
Resource
The installation of drainage ditches and removal of vegetation in preparation for vacuum harvesting alters the carbon dynamics of peatlands. However, we lack the measurements to understand the spatial...
Flexible migration by woodland caribou in Ontario, Canada
Resource
Abstract Recent studies of ungulate movement ecology suggest that seasonal movement tactics often vary within a population. The forest-tundra and forest-dwelling ecotypes of woodland caribou (...
Inuit Qaujimajatuqangit about Population Changes and Ecology of Peary Caribou and Muskoxen on the High Arctic Islands of Nunavut
Resource
Abstract Over the past 40 years, severe population fluctuations in Peary caribou ( Rangifer tarandus pearyi) and muskoxen ( Ovibos moschatus) living in the High Arctic of Nunavut has caused widespread...

Swamplands: Tundra Beavers, Quaking Bogs, and the Improbable World of Peat
Resource
In a world filled with breathtaking beauty, we have often overlooked the elusive charm and magic of certain landscapes. A cloudy river flows into a verdant Arctic wetland where sandhill cranes and...
The Impacts of Climate and Social Changes on Cloudberry (Bakeapple) Picking: A Case Study from Southeastern Labrador
Resource
Abstract The traditional subsistence activities of Indigenous communities in Canada's subarctic are being affected by the impacts of climate change, compounding the effects of social, economic and...
Tracking Vegetation Transitions Due to Invasion of Cattail (Typha) in Lake Superior Coastal Peatlands
Resource
Invasive cattails ( Typha angustifolia and Typha × glauca) pose a problem for many Laurentian Great Lakes wetlands, especially sedge/grass meadows. In western Lake Superior, early signs of invasion...
