Description of research

My research interests focus on understanding the environmental and ecological factors that determine the spatial patterns of abundance in animal populations and the makeup of species in disturbed landscapes. The main research topics are habitat selection, trophic interactions and intra- and inter-specific competition, and wildlife responses (native and exotic species) to natural and anthropogenic landscape disturbances. I use an approach combining theoretical and experimental studies, in both the laboratory and the natural environment. The ultimate goal of my work is to help conserve animal populations and diversity.

  Effects of tree plantations on animal biodiversity

  Students: Justine Fontaine-Topaloff, MSc; Simon Côté Bourgoin, MSc

  Forest plantations are increasingly used around the world to meet the demand for wood. The effects of these plantations on local biodiversity and landscape are not yet fully understood, particularly in Quebec, which raises concerns among organizations, including forest certification bodies. The main objective of these projects is to understand the effects of forest plantations on animal populations and communities (birds, small and large mammals, invertebrates), with the aim of helping to establish plantations that maintain biodiversity.

  

  Role of anthropogenic disturbances in the success of invasive species introduced in the forest

  Students: Anna Mazaleyrat, PhD; Julien Bellerose, MSc

  Habitat disturbance is recognized as facilitating the success of invasive species introduced in the forest, resulting in the loss of native species. However, little is known about the underlying mechanisms. These projects aim to identify these mechanisms, focusing on introduced species of understory plants and slugs.

  

   

  Role of white-tailed deer in maple regeneration problems

  Students and Postdoctoral Fellow: Florian Mézerette, PhD; Aurdey-Anne Lorrain, MSc; Hélène Le Borgne, Postdoctoral Fellow

  Sugar maple has experienced recurring episodes of decline within its range since the early 20th century. In addition to reduced growth and mortality of branches or whole trees, there is also a significant failure of regeneration in decaying or wasting stands. Several factors have been identified to explain this phenomenon, including soil acidification and overgrazing by large herbivores (moose, white-tailed deer), but the relative role of these factors is still not fully understood. These projects aim to determine the relative role of deer grazing in problems of maple regeneration, as well as to better understand the spatio-temporal variability of grazing pressure observed.
