Viv Tulloch has developed a multi-species model, in collaboration with CSIRO, as part of her PhD research.
It models interactions between krill and five key baleen whale predators, and predicts their future recovery given changes in primary productivity from climate change.
Viv was invited to present her research findings to the International Whaling Commission (IWC) Scientific Meeting held in Slovenia.
As stated in an executive summary of the presentation:
"...the model presents an updated assessment for blue, fin, humpback, right and minke whales as a basis for exploring ecosystem dynamics in the Southern Hemisphere. Results demonstrate key differences in population trajectories and estimates between models that account for, or ignore, predator-prey linkages. This is a strategic model that provides a platform for exploring additional hypotheses and management strategies, and is being modified in a step-wise fashion to explore predator-prey interactions and the effects of future environmental change on krill and whales."
The full report from the meeting will be available from the IWC soon.
