Programme de recherche

Le programme de recherche de la professeure Bernadette Pinel-Alloul se concentre sur l’écologie du plancton. Elle étudie la variation du plancton dans l’espace, en particulier ce qui influence sa répartition et sa composition (ex. : l’acidité de l’eau, l'eutrophisation, l’utilisation du bassin versant, leur niveau dans la chaîne alimentaire). De façon plus appliquée, elle étudie l’impact de l’environnement naturel et de l’être humain sur ces organismes : coupes forestières, précipitations acides, mise en eau de réservoirs nordiques, eutrophisation des lacs, contamination aux métaux lourds, etc.

Academic background

Ph.D. 1970-1975: Aquatic ecology, Université de Montréal (Quebec, Canada).

M.Sc. 1968-1969: Université de Montréal (Quebec, Canada).

B.Sc. 1968: Animal biology, Université de Lille (France).

Research interest

The research program is subdivided into both fundamental and applied fields and is mainly concerned with: (1) heterogeneity of lake planktonic communities over different spatial scales and its generative abiotic and biotic processes, (2) metal bioaccumulation and transfer in aquatic food chains, (3) impact of acid deposition on lake planktonic ecosystem, (4) development of biotic indices of environmental quality, (5) impacts of reservoir impoundment and (6) effects of watershed use and restoration technologies on planktonic ecosystem and water quality. The research is carried out by multi-lake comparative analysis as well as by experimental approaches in the field and the laboratory.
