Prédiction spatiale de l’indice de biodiversité potentielle en forêt boréale mixte par télédétection

Les vieilles forêts jouent un rôle central dans le maintien de la biodiversité et des fonctions écologiques forestières, mais leur prise en compte dans l’aménagement forestier demeure limitée par des outils de diagnostic reposant principalement sur des seuils d’âge et des proportions de forêts résiduelles. Cette approche ne permet pas d’évaluer adéquatement la qualité écologique […]

Motor unit identification during fatigue using high density electromyography

La capacité du système moteur humain à produire et à contrôler la force repose sur l’interaction dynamique entre le système nerveux et les muscles squelettiques. Lors de tâches prolongées ou exigeantes, cette interaction s’adapte afin de maintenir la performance malgré la diminution progressive des capacités neuromusculaires associées à la fatigue. Ce projet vise à comprendre […]

Population genetics of an obligate mutualism: swollen-thorn acacias and their ants

Mutualisms, interactions in which two species benefit one another, are universal. It is estimated that every species engages in at least one mutualism. Mutualisms play key roles in natural ecosystems–providing essential ecosystem services, like pollination and nitrogen fixation–and even influence where species live. Despite their importance, very little is known about how mutualisms influence the […]

Medial Lateral Separation and Age Differences on Collision Avoidance Behaviours

Avoiding collisions with other pedestrians is a daily necessity for individuals across all age groups. Unfortunately, age-related declines in older adults’ motor and sensory systems can negatively impact their ability to safely navigate the environment. For instance, decrements in muscular strength, balance, and cognitive function can impair one’s ability to adapt locomotion to environmental constraints. […]

Investigation of gut microbiome shift in Japanese dairy calves in response to heat stress

This project will expand on a previous project on heat stress on calf microbiome with the prevalence of climate change. Young calves are particularly vulnerable because their immune and temperature regulation systems are not fully developed, and their gut microbiome—the community of bacteria, archaea, and viruses that support digestion and health—is still forming. In Japan, […]

Physiopathological basis of a new neuro-ophthalmological disease linked to “chemsex”.

Chemsex refers to the recreational use of psychoactive substances to enhance sexual experiences and is associated with increased sexual risk-taking and mental health issues, including substance dependence. One of the most commonly used substances in this context is isopropyl nitrite, owing to its low cost, wide availability, and ease of inhalation. In recent years, growing […]

L2M – Smart Lung Physio: LTC Adoption Readiness

Smart Lung Physio is validating adoption readiness for a respiratory care solution in long-term care. The project will map decision-makers, identify adoption drivers and barriers, and define non-clinical pilot readiness criteria to support an evidence-based go/no-go decision for an LTC pilot.

Les gros arbres habitats sont-ils des parapluies pour la rétention de dendromicrohabitats en forêt boréale mixte?

L’aménagement durable des forêts boréales du Québec doit concilier la récolte du bois et la conservation de la biodiversité, un équilibre difficile en raison de la forte utilisation des coupes totales. Historiquement dominées par des vieilles forêts, ces régions abritent une grande diversité de dendromicrohabitats (cavités, champignons, épiphytes), essentiels à de nombreux organismes. La perte […]

Understanding the role of astrocytes in neuroendocrine adaptation to stress

Stress signaling in the brain is critical for adaptation in the face of various challenges. Adaptation to stress requires the engagement of specific brain circuits that control production of stress hormones including cortisol, including the hypothalamus-pituitary-adrenal (HPA) axis. Overactivation of HPA axis however, results in pathological stress that can contribute to psychiatric disorders including anxiety […]
