January 10 Catching your Breath - Hypoxia and Hot Fish in the Face of Global Change
By Lauren Chapman (Professor and Canada Research Chair, Biology, McGill)
For water-breathing organisms like most fishes, dissolved oxygen is one of the most critical factors in their environment, limiting habitat quality, growth, and survival. While low oxygen (hypoxia) occurs naturally in some waters with low light and low mixing (ie. swamps), environmental degradation is dramatically increasing the frequency and severity of hypoxic events, to the point where hypoxia is now considered one of the most serious manifestations of human-induced stress to inland and coastal waters. This talk takes you to equatorial waters of East Africa to focus on this pervasive environmental stressor and its potential interactions with climate change. Dr. Lauren Chapman is a Professor of Biology at McGill University where she holds a Canada Research Chair in Respiratory Ecology and Aquatic Conservation. Her research focuses on problems of environmental stressors in aquatic systems and adaptations of fishes to extreme environments. For over two decades, Dr. Chapman’s program has been is strongly embedded in international research and training in East Africa fostered by strong linkages with the National Fisheries Resources Research Institute and Makerere University of Uganda.
