Fall is here: Why do some trees lose their leaves while others stay green?

Charles Marty, Université du Québec à Chicoutimi (UQAC)

The leaves of evergreen species acquire carbon over the long term and improve nutrient conservation, whereas short-lived leaves favour rapid carbon acquisition.

The combined impact of increasing temperatures (2 to 8°C by 2100) and forest development in the mixed boreal forest could modify the growth and distribution of temperate species. (Shutterstock)

Québec’s hardwood trees could move north. Here’s how that could affect the boreal forest landscape

Research shows that the distribution of temperate hardwoods (sugar maple, red maple and yellow birch) could be shifting northward, which would have serious consequences for the boreal forest.

Forest fires were mostly started by lightning. Their spread was then exacerbated by a lack of precipitation and abnormally high temperatures. (Victor Danneyrolles)

Québec’s summer 2023 wildfires were the most devastating in 50 years. Is the worst yet to come?

Dorian M. Gaboriau, Université du Québec en Abitibi-Témiscamingue (UQAT); Jonathan Lesven, Université du Québec en Abitibi-Témiscamingue (UQAT); Victor Danneyrolles, Université du Québec à Chicoutimi (UQAC), and Yves Bergeron, Université du Québec en Abitibi-Témiscamingue (UQAT)

The forest fires of the summer of 2023 in Québec were devastating. It was the worst year in 50 years. But with climate change, the worst may be yet to come.

A better understanding of the interactions between snow cover and forest will help improve hydrological models and thus ensure public protection against flooding. (Benjamin Bouchard)

Understanding the dynamics of snow cover in forests can help us predict flood risks

A better understanding of the interactions between the boreal forest and snow will make it possible to improve hydrological models and ensure optimal management of the resource.
