    Scotty Creek, Northwest Territories (NWT), Canada, has been the focus of hydrological research for nearly three decades. Over this period, field and modelling studies have generated new insights into the thermal and physical ...
  • Shrub changes with proximity to anthropogenic disturbance in boreal wetlands determined using bi-temporal airborne lidar in the Oil Sands Region, Alberta, Canada 
    Chasmer, Laura; Lima, E. Moura; Mahoney, Craig; Hopkinson, Christopher; Montgomery, Joshua; Cobbaert, Danielle (ElsevierArts and ScienceDepartment of Geograpy and EnvironmentUniversity of LethbridgeUniversidade Federale de Santa MariaAlberta Environment and Parkshttps://doi.org/10.1016/j.scitotenv.2021.146638, 2021)
    In this study, we used bi-temporal airborne lidar data to compare changes in vegetation height proximal to anthropogenic disturbances in the Oil Sands Region of Alberta, Canada. We hypothesize that relatively low-impact ...
  • Peatland-fire interactions: a review of wildland fire feedbacks and interactions in Canadian boreal peatlands 
    Nelson, Kailyn; Thompson, D.; Hopkinson, Christopher; Petrone, R.; Chasmer, Laura (ElsevierArts and ScienceDepartment of Geograpy and EnvironmentUniversity of LethbridgeGreat Lakes Forestry CentreUniversity of Waterloohttps://doi.org/10.1016/j.scitotenv.2021.145212, 2021)
    Boreal peatlands store a disproportionately large quantity of soil carbon (C) and play a critical role within the global C-climate system; however, with climatic warming, these C stores are at risk. Increased wildfire ...
