Recherche et / ou projets en cours

Linda Nichol, qui s'est jointe au ministère des Pêches et des Océans en 2001 en tant que chercheur biologiste, a travaillé sur les loutres de mer et les cétacés dans la région du Pacifique. Mme Nichol a participé à des études sur le terrain des mammifères marins dans le Pacifique canadien en 1988 dans le cadre de sa maîtrise sur l'écologie de l'alimentation des orques résidents. Depuis, elle a participé à des recherches sur la surveillance des orques par photo-identification et par analyse acoustique, a étudié les effets des bruits d'origine humaine sur le marsouin commun et a compilé des registres des prises des pêches à la baleine en tant que données biologiques sur l'évolution des populations des grands cétacés. Par le passé, elle a également travaillé sur des projets concernant les oiseaux marins côtiers, les végétaux et invertébrés intertidaux ainsi que la surveillance environnementale. Ses recherches actuelles se concentrent sur l'état de la conservation de la loutre de mer, qui est inscrite sur la liste des espèces menacées en vertu de la Loi sur les espèces en péril du Canada. Elle participe également à des études sur le terrain sur des espèces de cétacés protégées par la LEP. Ses recherches sur la loutre de mer incluent l'évaluation de la population, la modélisation de l'habitat et l'évaluation des menaces potentielles pour cette espèce (diversité génétique, maladie, santé, etc.). Les recherches sont menées en collaboration avec des collègues du milieu universitaire, le Vancouver Aquarium Marine Science Centre et des chercheurs d'autres pays.
