The human population is increasing, as is the number of individuals living within cities. This is increasing the demand for infrastructure, which cities are now attempting to meet through densification instead of urban sprawl. However, densification is threatening the quality and extent of urban greenspace. One atypical form of greenspace, urban cemeteries, may be better […]

En 2019, environ 200 000 Canadiens seront diagnostiqués d’un cancer. La moitié de ces patients seront traités par radiothérapie. Si l’objectif est de maximiser l’irradiation de la tumeur et minimiser l’impact sur les organes sains environnants, des erreurs pouvant avoir des conséquences désastreuses se produisent. Actuellement, aucune vérification en temps réel de la dose radioactive […]

The Mottled Duskywing is an endangered butterfly species in Canada. In order to reverse the decline of this species, research is required to fill in knowledge gaps regarding the species biology and life history. There are currently no data available on population size, survival rates of adult or juvenile life stages, dispersal, or optimal habitat […]

Sustainable production of biofuel from biomass is the subject of my project at the University of Zaragoza and institute of coal chemistry (CSIC) located in Zaragoza, Spain. The overall objective of the project is design of an efficient biomass-to-biofuel conversion process to reduce emission of carcinogenic compounds into the atmosphere. In this regard, I will […]

Soot particles are carbonaceous aggregates which are produced as the result of incomplete combustion. They are mainly added to the atmosphere from coal power plants, chemical factories and motor vehicles and they account for approximately 10 to 15% of the total atmospheric aerosol mass. These particles are known to have a detrimental effect on both […]

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 […]
