Species loss in food-web networks

This research will provide critical knowledge on how species loss affects ecosystem functioning in species-poor Northern ecosystems. Currently it is unknown whether the consequences of species-loss in Northern ecosystems will be similar to warmer regions or whether there are unique properties associated with Arctic species and communities which may exacerbate the consequences of species loss. This research will extend my NSERC Discovery Grant on species loss in food-web networks to include species-poor Northern communities from Churchill, Manitoba, Resolute Bay, Nunavut, and Iqaluit, Nunavut to determine the potential consequences of species loss in species-poor Northern ecosystems.
