Most forests slow down climate warming by removing CO2 from the atmosphere and storing it in biomass and soils. However, how much CO2 they remove depends on how much CO2 different forest compartments (vegetation and soils) take up from or release to the atmosphere. New sensor technologies have been developed allowing year-round measurements of CO2 […]

In response to the current climate crisis and since the Paris COP21, there has been widespread international agreement on limiting warming to < 2°C. Two recent IPCC reports have emphasized that the most feasible pathway to limiting warming to 2°C or less is to deploy both climate mitigation (emissions reduction) and intervention (Carbon dioxide removal) […]

L’exploitation des sites miniers nécessite une importante consommation d’eau. En cas de rejet en milieu naturel, les contaminants (dans le cas présent, l’azote ammoniacal, mais aussi les nitrites et nitrates) présents peuvent avoir des impacts sur l’environnement. La mise en place d’une filière de traitement est alors nécessaire. Celle-ci doit permettre de répondre aux normes […]

The purpose of this project is to study the behaviour of western painted turtles during the nesting season. These species are currently in decline in British Columbia due to urbanization and a loss of nesting habitat. In recent years, the construction of man-made nesting beaches has been widely used in an effort to help this […]

Southern mountain caribou inhabit high elevation forests and parkland in late winter when snow depth facilitates access to arboreal lichens, their preferred winter food source. Use of these habitats coincides with human recreational use of these same areas by helicopter skiing, commercial backcountry skiing and snowmobiling (backcountry recreation). The COVID-19 related travel restrictions implemented in […]

Wildfire incurs major environmental and economic losses in many areas of the world. Although climate change is playing an important role in changing fire frequency and magnitude, human management strategies can play an arguably comparable role. Managers must choose from a range of strategies to ensure viability of forest stands, but research supporting efficacy of […]

La gestion des matières résiduelles est problématique dans les communautés nordiques éloignées au Québec. La localité de Radisson – la communauté allochtone la plus au nord du Québec – n’échappe pas à cette réalité. Située à proximité de la Baie-James et du complexe hydroélectrique La Grande, Radisson écope d’un volume important de résidus de construction […]

Ocean alkalinity enhancement (OAE) is rapidly emerging as a potential technique to mitigate against the worst impacts of climate change. However, little is known regarding the potential biological and ecological impacts of introducing alkaline base into the coastal ocean to capture CO2, reversing ocean acidification in the process. Specifically, it remains unclear whether the phytoplankton […]

Water resource management has been a challenge facing many regions worldwide, including Vietnam and Canada. Reservoirs are crucial in water management. The project is to further the intern’s PhD research on improving the reservoir operational rule with a case study of Thac Mo Reservoir in southern Vietnam. A model combining a rainfall-runoff framework, reservoir operating […]

Chez les vertébrés, le mode de reproduction le plus fréquent est la reproduction sexuée, ce qui implique la fusion de gamètes, soient l’ovule et le spermatozoïde, provenant de deux parents de sexes opposés. Dans certains cas rares, le mode de reproduction d’une espèce peut devenir asexuée c’est-à-dire, une reproduction par soi-même. Chez les vertébrés, ces […]

Vegetation in the Lower Columbia Valley in the West Kootenays of BC has been affected by historical emissions from the smelter in Trail, BC. Following logging of the valley for fuel and building materials, metal and SO2 emissions impaired forest regeneration on low valley slopes. A hardy tree species in the legume family native to […]

Dans l’est du Canada, la gestion durable des forêts de feuillus et des peuplements de bois mixtes passe, entre autres, par l’implémentation d’une sylviculture de précision. En effet, dans ce type de peuplement, l’identification des tiges de haute valeur marchande et de celles à conserver est un élément primordial tant au niveau économique qu’au niveau […]
