Openings and opportunities for new students

(1) How to cross roads? Patterns of road mortality and the use of existing crossing structures in the Laurentians  

This project includes two MSc students, starting in May 2025. Negative impacts of roads on wildlife populations are increasing worldwide. Road reduce ecological connectivity and increase wildlife mortality, but almost no research has been done on this topic in the area around Mont Tremblant (in the Laurentians, Quebec) so far, even though this region is under increasing anthropogenic pressure. Therefore, this research is urgently needed. The students will collect data to investigate patterns of wildlife mortality on two roads in the Laurentians and the use of existing crossing structures by wildlife with a focus on large and medium-sized mammals, reptiles, and amphibians. Fieldwork will start in May 2025. Both positions are fully funded by Mitacs in collaboration with Éco-corridor laurentien (ÉCL). Good knowledge of French is an important advantage for these two positions. 

(1) Comment traverser les routes ? Tendances de la mortalité routière et de l'utilisation des structures de franchissement existantes dans les Laurentides

Ce projet inclut deux étudiant(e)s en maîtrise, à partir de mai 2025. Les impacts négatifs des routes sur les populations d'animaux sauvages sont en augmentation dans le monde entier. Les routes réduisent la connectivité écologique et augmentent la mortalité de la faune, mais presque aucune recherche n'a été effectuée sur ce sujet dans la région du Mont Tremblant (dans les Laurentides, au Québec) jusqu'à présent, même si cette région est soumise à une pression anthropogénique croissante. Il est donc urgent de mener ces recherches. Les étudiant(e)s recueilleront des données pour étudier les patrons de mortalité de la faune sur deux routes dans les Laurentides et l'utilisation des structures de passage existantes par la faune, en mettant l'accent sur les mammifères de grande et moyenne taille, les reptiles et les amphibiens. Le travail sur le terrain débutera en mai 2025. Les deux postes sont entièrement financés par Mitacs en collaboration avec Éco-corridor laurentien (ÉCL). Une bonne connaissance du français est un advantage important pour ces deux postes.

(2) Assessing the impact of forest fires under climate change and the influence of forest fragmentation

Various thesis topics are available, for example: (1) "How does the use of crossing structures along roads by humans influence their use by wildlife (mammals)?",  (2) "How long do wildlife fences need to be to avoid a fence-end effect?", (3) "Is it better to install a Few Long Or Many Short (FLOMS) fences to reduce wildlife mortality on roads?", (4) "How to set limits to urban sprawl?", (5) "What are the similarities and differences between the various definitions of 'urban sprawl' proposed in the literature?", and (6) "How effective are urban growth management strategies at mitigating urban sprawl?"  

I am also looking for 2 new Honours students to work on several research questions, for example on the question of how the use of existing crossing structures along roads by humans influence affects their use by wildlife (mammals), and on a project about procedures to introduce limits to control environmental degradation. More information HERE. Various other topics are also available. These Honours theses will start in September 2025.
