What happens to a river when it is polluted or invaded by non-native species? Can they be restored to their previous state or are the communities and functional groups permanently altered? How does the ecology change? These are the questions driving University of Glasgow and IBIS researcher Dr Jennifer Dodd. An aquatic ecologist “with a bent towards freshwater”, Jennifer has been fascinated by aquatic systems since she was old enough to wear a pair of “wellies” and go grubbing around in rivers looking for the small things: a childhood enchantment she has turned into a successful and varied career. Join us as we discuss everything from killer shrimp to jewellery, and get an insight into Jennifer’s fascinating research.
