As atmospheric carbon dioxide concentrations continue to rise and global temperatures increase, there is growing concern about the sustainability, health, and carbon sequestration potential of forest ecosystems. Variable retention harvesting (VRH) ha

Climate change can affect lake water level and nearby landscape. Korosi and colleagues show recent expansion of shallow lakes in the Canadian Northwest Territories is flooding critical habitat for the wood bison, and demonstrate the trickle-down effe

Previous research suggests climate warming during the current century is likely to lead to an increase in the frequency and severity of wildfire. Recent wildfire seasons in northern Canada generally support these studies, with some of the worst fire

To reconstruct a mastodon diet and provide a snapshot view of environmental conditions in eastern Canada prior to the onset of the Wisconsinan glaciation, we analysed the faunal and floral components of dung associated with juvenile mastodon remains

This study utilized dendrochronology and long-term (2003–2017) eddy covariance (EC) carbon flux data to investigate the relationships between tree growth and gross ecosystem productivity (GEPEC) in different-age (15-, 42- and 78-year old) pine plan

Mercury (Hg) is a global pollutant emitted to the atmosphere from anthropogenic sources, which have varied over time in response to increased industrialization and pollution control measures. Tree rings have shown promise for reconstructing past atmo

Tree growth at northern treelines is generally temperature-limited due to cold and short growing seasons. However, temperature-induced drought stress was repeatedly reported for certain regions of the boreal forest in northwestern North America, prov

The inundation of terrestrial vegetation following landscape flooding is an important potential source of mercury to aquatic ecosystems, and may modify mercury cycling, such as through increased methylation. In the Great Slave Lowlands of Canada’s
Variable retention harvesting (VRH) is a silvicultural management practice that has been utilized to promote biodiversity, growth, and carbon sequestration in managed forests. VRH has been implemented as a climate mitigation strategy in response to i
