Viv Tulloch recently completed her PhD with CEED working on several different threat-management problems in collaboration with the Wildlife Conservation Society, The Nature Conservancy, CSIRO, and the International Whaling Commission (IWC).
At the most recent IWC Scientific Meeting in Slovenia, she presented findings from the multi-species model developed during her PhD. The model explores interactions between krill and five key baleen whale species that feed on krill, and predicts the future recovery of the whales given changes in primary productivity caused by climate change.
“The model presents an updated assessment for blue, fin, humpback, right and minke whales,” says Tulloch. “It provides 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.
