Humpback whaleViv Tulloch recently presented her research findings at the International Whaling Commission (IWC) Scientific Meeting.

Viv recently completed her PhD with CEED, which involved working on several different collaborative threat-management problems with the Wildlife Conservation Society, The Nature Conservancy, CSIRO, and the International Whaling Commission.

At the IWC Scientific Meeting, she presented findings from the multi-species model developed in her PhD in collaboration with CSIRO. It models interactions between krill and five key baleen whale predators, and predicts their future recovery given changes in primary productivity from climate change.

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.
