Recovering oil from underground reservoirs carries environmental and financial risks that can be minimized with prior knowledge of what fluids are there and how to efficiently extract them. Currently, fluid flow behaviour can be measured at reservoir conditions in large pressurized vessels capable of up to 150 atmospheres and 300°C, but measurements can take weeks […]

Nova Scotia forests boast the second highest private ownership rate in Canada, with almost 3 of 4.5 million hectares owned by 30,000 woodlot owners and private corporations. Because of this, forest management practices vary widely. Though the Nova Scotian forests traditionally consist of large, mature, unevenly aged trees that support both important biodiversity and a […]

Aux Îles-de-la-Madeleine (Qc), les mytiliculteurs s’approvisionnent en jeunes moules (naissain) dans une petite lagune (Bassin du Havre-Aubert, BHA) dont les stocks récoltés (captage) présentent une résistance particulière, du fait de leur importante diversité génétique. Toutefois, l’espace disponible pour les activités maricoles y est limité et le rendement de captage est variable d’une année à l’autre. […]

Une grande partie des rejets produits par l’industrie minière est souvent entreposée en surface. En contact avec l’oxygène atmosphérique et l’eau, les minéraux sulfureux contenus dans ces rejets s’oxydent et génèrent un drainage minier acide (DMA) comportant des contaminants préjudiciables pour l’environnement. Une des techniques utilisées pour contrôler ce phénomène est les recouvrements à plusieurs […]

Dams can be problematic for fishes, particularly those that migrate. In order to help fish move around dams, fisheries managers may construct fishways (aka “fish ladders”). However, these structures do not always function properly, often because they were built only to pass trout and salmon and are thus inappropriate for other species. This project aims […]

The present study investigates the impact of Eurasian honeybees on the functional diversity and reproductive ability of native stem-nesting bees. Honeybees have the potential to compete with native stem-nesting bees, however, currently no studies have examined this interaction in North American temperate forests. The main goal of this project is to develop a more mechanistic […]

Marine protected areas (MPAs) are a popular strategy for ocean conservation in Canada and several options are available to pursue this type of protection. However, the current federal and provincial processes for MPA development involve engagement in lengthy multi-stakeholder processes that can overwhelm local communities and their conservation objectives. An alternative strategy is the establishment […]

An emerging strategy for managing natural resources such as Canada’s forests more sustainably and responsibly is to use knowledge of how Mother Nature has done it to help guide our hand. This so-called ‘ecosystem-based” approach has gained favour with provincial and federal governments, as well as national and international certification agencies. One of the foundations […]

Afin d’améliorer son impact environnemental, nos partenaires souhaite remplacer une partie de ces produits d’origines pétrolières par un matériel innovant issus du produit de la recherche de l’UQTR. Ce produit, la bio-huile pyrolytique, est obtenue par pyrolyse de résidus forestiers de la forêt de La tuque. C’est-à-dire par combustion en absence d’oxygène. Le produit formé […]

La Corporation de la forêt d’enseignement et de recherche Macpès est un organisme qui a pour mandat d’assurer la gestion et la promotion d’un territoire forestier dédié à l’enseignement et à la recherche. En 2015, un suivi de l’entomofaune a été débuté sur ce territoire, et la Corporation souhaite pérenniser ce suivi afin d’obtenir des […]

It is well established that livestock producers are effective land stewards and contribute to high productivity and wildlife habitat on grazed lands. The effectiveness of many management practices are established, but uncertainty remains, particularly in interactions between practices at large-scales. We propose to track grazing patterns of bison and cattle using GPS collars at the […]

This project will combine filtration characterization and advanced 3D imaging and modelling of material structures to find ways to improve the recovery of process water from difficult-to-treat tailings that are the by-product of mining and mineral processing. This process is called solid-liquid separation and it is a critical area for the reduction of oil sands […]
