Dewatering Fine Tails by Evaporation: A Mathematical Modelling Approach
Resource
A one dimensional approach was used to model the evaporation process from fine tails. Understanding the complex interactions among the solids, water and external atmospheric demand is required
Dietary Reconstruction and Evidence of Prey Shifting in Pleistocene and Recent Gray Wolves (Canis lupus) From Yukon Territory
Resource
We investigate if and how diets of gray wolves from the Yukon have changed from the Pleistocene to the recent Holocene using dental microwear analysis of carnassial teeth and stable isotope analyses
Differences in Soil Fungal Communities between Forested Reclamation and Forestry Sites in the Alberta Oil Sands Region
Resource
Fungi play key roles in forest soils and provide benefits to trees via mycorrhizal symbioses. After severe disturbance, forest regrowth can be impeded because of changes in fungal communities. In 2013...
Differences in the Composition of Soils Under Open and Canopy Conditions at Two Sites Close-in to the Great Canadian Oil Sands Operation, Fort McMurray, Alberta
Resource
Soils sampled at sites 2.3 and 5.3 km south of the Great Canadian Oil Sands (GCOS) plant, Fort McMurray, respectively were found to differ statistically with reference to several macronutrients
Differential Post-Fire Vegetation Recovery of Boreal Plains Bogs and Margins
Resource
Peatland margins are a distinct ecotone especially vulnerable to deep smouldering in the Boreal Plains because they can experience greater water table drawdown during dry periods compared to peatland...
Digging Into Canadian Soils - An Introduction to Soil Science

Earth observation (EO), remote sensing (RS), and other digital technologies are emerging as powerful tools for monitoring the environment and collecting environmental data. These technologies can be...
Dimensionnement de la chaîne nationale d’approvisionnement en semences du Canada : Évaluation préliminaire sur les arbres et arbustes
Resource
In 2021-2022, the National Tree Seed Centre led a series of surveys to establish an accurate idea of genetically appropriate seed supply for forest landscape restoration (FLR) needs across Canada by...
Direct Planting of Poplar Stem Cuttings
Resource
Stem cuttings of balsam poplar and three poplar hybrids were directly planted onto reclamation material ontailings dyke slope. The overall rooting success was poor - direct planting is not recommended
Disconnectivity Matters: The Outsized Role of Small Ephemeral Wetlands in Landscape-scale Nutrient Retentions
Resource
Wetlands protect downstream waters by filtering excess nitrogen (N) generated from agricultural and urban activities. Small ephemeral wetlands, also known as geographically isolated wetlands (GIWs)...
