Amber’s research is centred on improving our understanding of the biology, ecology, physiology, movement behaviour and habitat connectivity of estuarine and coastal fishes, with emphasis on the impacts of overfishing and climate change. For the past two decades, her research has focused on the movement ecology and habitat connectivity (using acoustic telemetry), and the role of critical nursery habitats for estuarine and coastal fishes. She realised that identification of essential fish habitats is key to effective marine and estuarine spatial planning. More recently, she has focused on the causes and consequences of fish movement behaviour at an individual, population and species level through pattern-based field and process-based physiological research. As a result, she has recently expanded her research interests into examining behavioural plasticity of fishes through investigating fisheries-induced evolution on fish physiology. This research involves understanding the proximate causes (mechanisms and processes e.g. physiology) and ultimate causes (ecological and evolutionary consequences) of fish behaviour to better understand anthropogenic impacts such as climate change and overexploitation. Amber is also involved in the biological and social aspects of recreational fisheries to ultimately improve angler behaviour and fish health and survival – she came to realise that to effectively manage fish; you need to manage people.
