RESEARCH INTERESTS:

I am primarily a behavioural ecologist specializing in fish and aquatic ecosystems. I have applied the study of behaviour to several fields including invasion ecology, evolutionary ecology, ecotoxicology, aquaculture and conservation. Much of my research involves behavioural interactions between native and invasive fish species with the dual aims of using these systems to inform on ecological theory and providing information necessary for conservation efforts. Behaviour, while often overlooked, is of fundamental importance, and many researchers now emphasize the need to study behaviour in biological invasions. Other areas of interest comprise the mechanisms and functions of airbreathing in fishes and the characterization of crypsis and its role in avoiding competition and predation.

My current focus combines invasive species impacts and climate change effects using the mosquitofish, Gambusia affinis, one of the 100 worst invasive species worldwide, as the model species. Investigation of the interactions between climate change and biotic invasions in freshwater ecosystems is of critical global importance in the modern world and for future generations. A major climate change influence for invasive species impacts is increased temperatures and one potential effect that has received little attention is changes in cognitive abilities. A key attribute of successful invasive species is behavioral flexibility and temperature has been shown to enhance learning and innovation in several taxa. Depending on the direction of effects, climate change may combine synergistically with changes in cognitive abilities to enhance the invasive success of freshwater species.
