Our goal is to understand how aquatic animals integrate the use of behavioural habitat choice and physiological plasticity to respond to common environmental challenges including temperature extremes, hypoxia, and turbidity. We are interested in learning why these processes can interact via both positive and negative feedback. To achieve this goal, we take a comparative approach that investigates both ends of the “environmental tolerance” continuum – species that are highly tolerant of change, and those that are extremely sensitive and endangered. Our current focuses are a) the plasticity of the respiratory system in fishes (but we collaborate to study plasticity of other systems) and b) the habitat requirements of endangered native fishes to inform conservation and future reintroductions.

Work in the Laberge lab attempts to understand how variation in brain structure and size influences organismic function, and identify the factors that drive evolution and plasticity of the nervous system. Current projects on this topic study variation in structure and size of the brain in populations of fish and amphibians, the proximate mechanisms generating this variation, and the functional consequences of this variation. Additionally, the lab is involved in collaborative efforts aiming to develop novel indicators of ecological performance and chronic stress in wild fish.
