As part of the Flow-MER Food Webs and Water Quality theme, we are developing a bioenergetic food web model by incorporating a range of existing and new data relating to food web dynamics in wetlands, flood channels and rivers during Commonwealth environmental watering. In this webinar, we talk about the model and how we plan to use it to demonstrate rates of carbon transfer and production in food webs under different environmental flow scenarios, exploring two key questions:
- How does environmental watering influence the flow of energy through to vertebrate consumers such as fish and birds?
- How can energetics response model support the prediction of trophic carrying capacity of rivers and wetlands in response to environmental water delivery?
Paul’s research focus areas include food webs, how energy flow in ecosystems may be changed by both biotic and abiotic disturbance, or by man-made intervention, and how invasive species alter the structure and function within freshwater ecosystems. He is also interested in the responses of basal resources to altered ecosystem conditions, and how this influences food webs.
James research focuses on food webs, water quality, and ecosystem productivity. He is interested in understanding how human activity is disrupting aquatic food webs and assessing potential management interventions. James has experience conducting environmental flow studies in inland and coastal catchments and has worked for the NSW government implementing water quality and ecological aspects of the MDB Plan.
