L’exploitation de la centrale hydroélectrique Romaine-1 cause sur la rivière Romaine des fluctuations du débit susceptible d’entraîner le déplacement des saumons juvéniles en dehors de leurs habitats préférentiels. Il est donc essentiel de déterminer si le mode de gestion actuel des débits permet aux saumons juvéniles de se maintenir dans leurs habitats. Pour étudier la […]

Étant consciente de la dégradation de l’environnement et du risque qui en découle pour la santé et la sécurité des citoyens, mon projet de thèse réalisé à Valence en Espagne permettra de dégager un portrait des comportements environnementaux pratiqués dans notre société en comparaison avec ceux de l’international. Ainsi, l’étude permettra de sortir des sentiers […]

Underwater visual analysis (UWVA) is a passive and non-invasive method gaining popularity in freshwater systems. UWVA uses underwater cameras and/or snorkel surveys to assess species richness and abundance. UWVA could also be used to detect endangered and invasive fishes, which is important for conservation and management of freshwater ecosystems. To determine the applicability of the […]

We will use a database of more than 30 years of scientific survey and citizen-science observations of common loon breeding on lakes in Ontario, as well as other parts of Canada, to determine whether loons now breed successfully on lakes where they were negatively affected by acid rain (and other human threats like development). Our […]

Neonicotinoids are the largest-selling, fastest-growing group of insecticides worldwide. Due to their chemical properties (high water solubility) and current agricultural application practices, neonicotinoids and their mixtures are routinely detected in global freshwater environments. As these compounds can persist in light-limited environments and are highly toxic to invertebrates (particularly arthropods), the effects of long-term exposures to […]

Plastic litter currently accumulates in oceans, causing a ‘plastic soup’. Therefore, the past years many biodegradable plastics were developed and marketed. Most biodegradable plastics after their use end up in organic recycling, where materials are turned into compost and renewable energy (biogas and heat). However, many biodegradable plastics that are claimed to be ‘biodegradable’ are […]

The Caribbean tourism sector is critically important to the Caribbean economy and highly sensitive to climate change and its impacts. Climate-sensitive industries are exploring how to make best use of outputs of climate models, weather forecasting tools and early warning systems as strategies to boost their viability as climate change intensifies. Tools such as these […]

In this project, we would model the underwater acoustic behavior. Using the model, we will calculate the distance to the source of the sound with high accuracy despite the underwater environmental conditions. The second part of our project is to classify the source producing the sound. Our algorithm will be able to detect and distinguish […]

The project will involve running terrestrial biosphere models on JPL’s supercomupters. Specifically, my first task will be focused on modeling the carbon cycle. This cycle describes how carbon circulates through the atmosphere, vegetation and ground. With climate change and rising temperatures, this cycle has been changing. This is why we are interested in modeling it […]

Arctic temperatures are increasing twice as fast than the global average. In fjordic ecosystems of Svalbard, the Atlantification, the process leading to warmer conditions in the area impose new challenges to Arctic living community. Those changes alter cryosphere regime (i.e., ice component covering the surface) and associated species habitats. The black-legged kittiwake is a predator […]

The use of unconventional heavy oil, such as the bitumen derived from oil sands, has progressively increased, placing these materials as a compelling alternative to meet short- and long-term energy demands. Nevertheless, the current technologies available to exploit and upgrade this crude have critical challenges, such as high production costs, lower energy efficiency, and, even […]

Population growth and economic development exert significant threats on ecological and environmental systems of rural areas in China. Integrated socio-economic and eco-environmental management is desired for addressing these threats, but is challenged by the conflict of multiple developmental objectives and the intervalness of uncertain system characteristics. Therefore, this project aims to provide scientific support for […]
