Mountainous environments present a variety of risks to human populations in the surrounding communities. Landslides in mountainous regions are a particularly deadly form of natural hazard due to their unpredictability and potential scale, resulting in thousands of deaths every year. Due to current climate warming as a result of human actions, the risk of these […]

To avoid dangerous climate change, large quantities of carbon dioxide must be removed from the atmosphere. Forest growth is one of the most efficient strategies for achieving this, with tropical secondary forest key to recovering carbon stocks. The carbon benefit of secondary forest, which grows on cleared land following abandonment, is determined not only by […]

Fisheries are the main global threat to elasmobranchs (sharks and rays). Elasmobranchs commonly display conservative life history traits (slow growth, long life, late sexual maturity and low fecundity), making them extremely vulnerable to non-natural mortalities. However, there is significant variation, with some species exhibiting life history traits more resilient to exploitation. In order to assess […]

Puisque les changements climatiques sont déjà ressentis et le seront de plus en plus, il est nécessaire de s’adapter à de conditions environnementales sans précédent. Une quantité grandissante de programmes de financement vise maintenant à soutenir les communautés dans leurs démarches d’adaptation; par conséquent, le besoin d’évaluer l’atteinte des cibles d’adaptation devient de plus en […]

While most people get drinking water through underground water pipes, in some areas these pipes only provide water for a few hours each week. Globally, more than one billion people are served by these “Intermittent Water Supply Systems (IWS)”. In severely degraded systems, keeping pipes empty most of the time can reduce leakage and conserve […]

Ce travail de thèse, mené en cotutelle entre le laboratoire IMS (Univ. Bordeaux) et l’UMI CNRS LN2-3IT (Univ. Sherbrooke), concerne le développement d’un capteur optique de polluants afin de détecter des traces de métaux lourds ou pesticides dans l’eau. Le capteur photonique intégrée réalisé en oxynitrure de silicium (SiON) sur substrat de Silicium, se base […]

Boron-containing organic materials are increasingly important in high-tech applications such as sensors, optoelectronics and pharmaceuticals. We recently developed a highly reactive nickel precursor that was able to activate a variety of substrates and showed a strong predilection for unsaturated systems. The proposed research aims to test the ability of this system to activate a variety […]

Ce projet de recherche, dans le cadre de mes recherches doctorales, à la Faculté de droit de l’Université de Montréal, sous la supervision de Professeure Julie Biron, me permettra d’approfondir les recherches en ce qui concerne la conformité dans les sociétés canadiennes dont certaines opèrent en Afrique subsaharienne dans le secteur minier. A cet effet, […]

For thousands of years before European arrival, the Indigenous people of the Rocky Mountains regularly used low-intensity surface fires to keep forests clear of debris and fuel to mitigate the risk of high-intensity wildfire. The proposed project will investigate the historical extent of landscape management by Indigenous burning methods and explore the incorporation of Indigenous […]

Coral reef regime shifts occur when environmental stressors result in the benthic composition abruptly transitioning from a coral dominated reef to one dominated by macroalgae. These shifts are a key conservation concern and have led to substantial degradation of coral reefs worldwide. In particular, climate-induced coral bleaching is now a leading threat to coral reefs, […]

La connectivité écologique est un des attributs les plus importants pour le maintien de la qualité de l’habitat et de la bioiversité présents sur le territoire. La mission de la compagnie Eco2Urb est d’assister les grands propriétaires d’écosystèmes et d’infrastructures naturelles pour augmenter la résilience de leur réseau écologique au bénéfice de la biodiversité ainsi […]

Water in lakes has a certain triple oxygen isotopic composition depending on the amount of precipitation and evaporation. Snails use oxygen from lake waters in order to mineralise their shells, thereby locking in the isotopic composition so that when snails die, they accumulate in sediments and can be analysed in order to build a record […]
