Les changements climatiques influencent la distribution des espèces. Notre étude souhaite étudier cet effet en divisant le climat en deux périodes : climat passé (1950-1980) et actuel (1980-2010) sur la base du basculement des températures mondiales en 1980. Cette étude est réalisée en forêt boréale et se concentre sur les bryophytes (mousses, hépatiques et sphaigne) […]

Many thermal power plants, including Bruce Power, rely on once-through cooling using water from the Great Lakes. The warmer water that is released back into the lake has the potential to impact temperature sensitive aquatic species that occupy the near shore water close to the discharges. The proposed research will investigate the genetic population structure […]

Les antibiotiques facteurs de croissance ajoutés dans les aliments pour animaux seront interdits ou leur utilisation sera considérablement restreinte dans le futur. Ainsi, plutôt que de seulement contrôler les maladies entériques, des efforts doivent être faits pour améliorer la santé de l’écosystème intestinal. Il existe de nombreuses alternatives telles les immunostimulants, les bactériophages, les peptides […]

Following the study of spinal cord transected (SCT) rat models being treated by fesoterodine fumarate (antimuscarinic drug) to prevent neurogenic detrusor overactivity, bladders of all 30 animals were conserved. It was observed that an early fesoterodine fumarate administration at the time of transection modulates bladder overactivity. However, the exact mechanism of action is not known […]

Forest tent caterpillars causes serious damage to hardwood forests across Canada, and outbreaks are currently on the rise in several provinces. Recent research by our team and others suggests that while parasites and disease play a key role in ending outbreaks, predators attacking young caterpillars could be important in preventing the start of outbreaks. This […]

Les peuplements de pins gris sur sables sont des stations forestières peu résilientes en cas de perturbation ou de changement dans la dynamique de végétation. Dans certaines conditions, l’aménagement forestier peut favoriser le basculement d’une forêt productive vers un état de clairière ouverte. En identifiant les facteurs en cause dans le déficit de croissance du […]

Extracellular nucleotides can favour inflammatory diseases via the activation of P2 receptors. The proinflammatory P2Y6 is the dominant nucleotide receptor in human and murine intestinal epithelial cells (IEC) and its expression increases during inflammation. Interestingly, we found that the blockade of P2Y6 totally prevented inflammation in the murine DSS model. This project will show whether […]

In Canada, 25,500 men will be diagnosed with prostate cancer in 2011, and 4,100 will die of the disease. New approaches are required to predict clinical outcome and personalized management of patients. Drs. Mai and Cayre will combine their two newly developed technologies and work towards obtaining a new solid biomarker that enables the assessment […]

Phytoplankton produce more than half of the world’s oxygen annually, and make omega-3 and omega-6 fatty acids, which are healthy fats that are passed marine food chains to fish for human consumption. These healthy fats are essential to our diet, meaning our bodies either cannot produce them at all or not in high enough quantities […]

The Oil Sands of Northern Alberta are a significant contributor to the Canadian economy but their management is also an important environmental issue for Canadians. Improved reclamation of tailings waste is an integral part of Oil Sands sustainability as an industry and understanding the role of microbes in the reclamation process has been a major […]

This project is about understanding the culture and practice of nurses in the city of Niteroi, Brazil in the context of community health with women, children, and youth. The data collection will involve my personal observation of nurses practices with their clients, meetings with staff and decision makers, as well, as health and professional authorities. […]

As a result of climate change and human-mediated movement of plants and animals, the establishment of invasive species is increasingly prevalent, with global economic and environmental consequences. Establishment in a new habitat requires successful reproduction in novel environments in the short-term, and successful invasion requires local adaptation in the long-term. Thus, invasive populations may initially […]
