FishAbstract. The general objective of Normand Bergeron’s research program is to better understand how fish exploit, over their life cycle, the mosaic of physical habitats comprised within an entire river system (i.e., the riverscape). This program involves projects grouped under three major research thrusts: (1) the development of innovative remote mapping methods and spatial analysis of physical habitat mosaics at riverscape scale; (2) the development of fish telemetry, especially passive integrated transponder (PIT) technology, for the identification of variable tactics of habitat exploitation by fish and their consequences on fitness; and (3) the analysis of the effect of habitat spatial structure and habitat fragmentation on fish production. In this presentation, Bergeron will present various examples of recent and ongoing research projects using Atlantic salmon (Salmo salar) and brook trout (Salvelinus fontinalis) as ecological models. A special emphasis will be put on two projects. The first concerns a new habitat mapping approach (called habitat chronology mapping) that integrates life stages habitat requirements and habitat connectivity to estimate the production potential of a river. The second analyses of the spatial behavior of fish attempting to pass road culverts and determines the potential effect of fish personality on this behavior. This work will provide stream ecologists highly novel tools and information concerning the dynamics of fish/habitat relationships that will help better manage fish populations.

Normand BergeronBio. After completing a Ph.D. in physical geography (fluvial geomorphology) at the University of Buffalo in 1994, Bergeron was appointed professor at the Institut National de la Recherche Scientifique (INRS) in Québec City, a graduate research university offering Master’s and Doctorate diplomas only. His research then took a serious biological twist and he now specializes in the analysis of fish/habitat relationships in rivers and streams. He is currently scientific director of the Centre Interuniversitaire de Recherche sur le Saumon Atlantique (CIRSA), a multi-disciplinary group of researchers dedicated to the study of the Atlantic salmon (Salmo salar) and its habitat. With his colleague André St-Hilaire, Bergeron manages a field station near the beautiful Sainte-Marguerite River, a salmon river that drains into the Saguenay fjord. He recently initiated the creation of RivTemp, a network dedicated to the monitoring of water temperature in Atlantic salmon rivers in Eastern Canada.

The objectives of the ThinkSpatial brown-bag presentations are to exchange ideas about spatial perspectives in research and teaching, to broaden communication and cooperation across disciplines among faculty and graduate students, and to encourage the sharing of tools and concepts.
