Research Summary:
Aquatic ecology and conservation, ecophysiology, evolutionary ecology, adaptive divergence, respiratory ecology, extreme environments.
In my research group, we integrate the morphology and physiology of fishes with their ecology and evolution to understand effects of environmental stressors on fishes. Current studies focus on consequences of hypoxic (low-oxygen) stress for fish performance and fitness traits, and interactions of hypoxia with other pervasive aquatic stressors: global warming, turbidity, invasive species, and overfishing. We focus on freshwater fishes in lakes, rivers, and swamps of East Africa, where we have long-term (30-year) field base in Kibale National Park, Uganda. We also conduct research Canadian fish species at risk, in particular imperiled cyprinid fishes.
