Recherche et / ou projets en cours

Le Laboratoire d’écologie fluvial du MPO entretient de vastes intérêts de recherche sur la biologie de la conservation, l’écophysiologie, le comportement du poisson, la bioénergétique et l’écologie aquatique pour fournir des conseils scientifiques aux programmes d’espèces en péril, de protection des pêches et d’espèces aquatiques envahissantes du MPO. Les poissons d’eau douce sont utilisés comme des modèles de recherche pour les expériences réalisées à la fois dans le laboratoire et au milieu naturel.

Nous avons plusieurs projets de recherche en cours dans le lac Winnipeg, y compris un projet à grande échelle de télémétrie pour étudier l’utilisation de l’habitat et le mouvement de plusieurs espèces de poissons (notamment buffalo à grande bouche, barbue de rivière, carpe commune, esturgeon jaune, dorée, lotte et malachigan) dans le bassin du lac Winnipeg comprenant les rivières Rouge, Assiniboine et Winnipeg, une enquête sur les juvéniles dans la zone littérale et pélagique ainsi qu’une examen sur la bathymétrie et l’habitat.

Plusieurs de nos projets mettent l’accent sur les espèces en péril, en particulier sur le chabot des montagnes Rocheuses, mène d’argent de l’ouest, meunier des montagnes, truite fardée versant de l’ouest, truite arc-en-ciel (populations de la rivière Athabasca),  et la tête carmin. Nous sommes également intéressés par l’impact des espèces aquatiques envahissantes sur l’écosystème et travaillons à une étude collaborative avec Canards Illimités Canada au marais Delta sur le lac Manitoba dans le cadre du projet d’exclusion de la carpe commune.

En ce qui concerne l’évaluation de l’habitat, nous développons un outil de modélisation convivial pour automatiser la production des courbes d’adéquation des habitats basées sur la bioénergétique pour les évaluations des débits réservés dans le cadre d’un projet collaboratif avec Jordan Rosenfeld et Brent Eaton de l’Université de la Colombie-Britannique.

Énoncés de recherches/projets

Mes recherches incluent l'écologie des poissons, la conservation et la restauration de leur habitat, les évaluations d'impacts environnementaux des effets anthropiques, de même que les impacts des changements climatiques sur les poissons. Je suis particulièrement intéressée aux enjeux suivants: (1) la biologie hivernale des poissons d'eaux douces en lien avec l'utilisation et la disponibilité de leur habitat, les coûts énergétiques de l'hivernation, la survie, ainsi que les modèles d'activités, (2) les passages des poissons à travers passages migratoires et les ponceaux, et (3) les effets de la turbulence sur les comportements des poissons et les coûts énergétiques.
