(Biography) Joël Bêty is an Adjunct Professor at the Université du Québec à Rimouski since June 2004 (Département de biologie). For the past 12 years, his work has centered on life history strategies and population dynamics of arctic birds, as well as their ecological role in arctic ecosystems. His projects deal with different “levels of organisation” (individual, population and community) and involve intense arctic field work on selected study systems. He combines analyses of long-term ecological data to short term field experiments to test hypotheses. At the individual level, he emphasizes the relationships among individual variation, breeding performance and fitness for some key life-history characteristics such as timing of migration and timing of breeding. These traits must be well understood to predict the responses of populations to climate change. At the community level, his current projects deal with the impacts of climate change on the arctic tundra. The specific goals are to investigate indirect effects of climate and trophic dynamics (e.g. predator-prey interactions) on arctic-nesting birds and their food.
