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...
On the Use of Mulching to Mitigate Permafrost Thaw due to Linear Disturbances in Sub-Arctic Peatlands
Resource
The presence or absence of permafrost strongly influences the hydrology and ecology of northern watersheds. Resource exploration activities are currently having profound effects on hydrological and...
Paleolimnological Assessment of Past Hydro-ecological Variation at a Shallow Hardwater Lake in the Athabasca Oil Sands Region Before Potential Onset of Industrial Development
Resource
Effective environmental monitoring requires knowledge of inherent natural variation. In the absence of pre-development monitoring of aquatic ecosystems, paleolimnological approaches have been...
Population Structure and Hybridization of Alaskan Caribou and Reindeer: Integrating Genetics and Local Knowledge
Project
Organization:
This PhD project is an interdisciplinary study. The researcher used interviews with herders and hunters, local observations, and genetic analysis to understand how historical processes influence...
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...
Predicting Patterns of Terrestrial Lichen Biomass Recovery Following Boreal Wildfires
Resource
New allometric equations to estimate lichen biomass from field measurements of lichen cover and height; allometries were consistent among ecoprovinces, suggesting generalizability
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...
Spatial and Temporal Variation in Forest Transpiration Across a Forested Boreal Peatland Complex
Resource
Transpiration is a globally important component of evapotranspiration. Careful upscaling of transpiration from point measurements is thus crucial for quantifying water and energy fluxes. In spatially...
Temperature, Moisture and Freeze–thaw Controls on CO2 Production in Soil Incubations From Northern Peatlands
Resource
Peat accumulation in high latitude wetlands represents a natural long-term carbon sink, resulting from the cumulative excess of growing season net ecosystem production over non-growing season (NGS)...
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...
The Boreal-Arctic Wetland and Lake Dataset
Resource
Here we present the Boreal–Arctic Wetland and Lake Dataset (BAWLD), a land cover dataset based on an expert assessment, extrapolated using random forest modelling from available spatial datasets of...
The Hydrology of Interconnected Bog Complexes in Discontinuous Permafrost Terrains
Resource
In the zone of discontinuous permafrost, the cycling and storage of water within and between wetlands is poorly understood. The presence of intermittent permafrost bodies tends to impede and re-direct...
The Influence of Postfire Recovery and Environmental Conditions on Boreal Vegetation
Resource
Climate change is increasing the frequency and extent of fires in the boreal biome of North America. These changes can alter the recovery of both canopy and understory vegetation. There is uncertainty...
The Study of Human-caribou Systems in the Face of Change: Using Multiple Disciplinary Lenses
Project
Organization:
This PhD project uses multiple disciplinary lenses to understand the dynamics of the social-ecological systems that are of critical importance to northern Indigenous Peoples of the Arctic. Barren...
The Study of Human-caribou Systems in the Face of Change: Using Multiple Disciplinary Lenses
Resource
Abstract Barren-ground caribou herds are part of social-ecological systems that are of critical importance to northern Indigenous Peoples of the Arctic, contributing to nutritional, cultural, and...
Unexpected Greening in a Boreal Permafrost Peatland Undergoing Forest Loss is Partially Attributable to Tree Species Turnover
