‘The aquatic environment is in a period of rapid changed with increasing temperature, decreasing oxygen, floods and surges and pollution. Our lab studies the impact of these changes on the animals living there and tries to understand traits and mechanism that allow animals to adapt and survive. In this talk I am going to share 3 short stories where we have investigated the impact of climate change on fish. The first is about an iconic British salmonid the brown trout and show how studies of movement and metabolism tell us the limits of their environmental tolerances in our local river systems. The second story is about embryonic sharks in UK coastal waters and how and why early life stages are particularly vulnerable for sharks. And the final story is about pollution, particularly the Deep Water Horizon oil spill, where we have shown how toxicants cause big problems for the fish heart. At the end of the talk, I hope you will see how physiology provides an important tool for conservation of aquatic species world-wide.’
Holly did her undergraduate and post graduate degrees in Canada working on fish heart function and temperature. She brought a Canadian postdoctoral fellowship to the University of Leeds, UK where she studied cellular cardiac function in fishes before gaining a lectureship at the University of Manchester. Her research lab in Manchester studies cardiac physiology in ectotherms and the mechanisms which maintain or adjust heart function in a changing environment. They apply this knowledge to cardiac health and disease and in predicting how organisms, populations, ecosystems and natural resources respond to environmental change and stressors.
