Dr. Greg Ruggerone joins us in-studio to discuss interesting biennial trends related to the boom and bust abundance levels of pink salmon and Southern Resident killer whale births and deaths. Since Southern Resident killer whales don’t directly prey upon pink salmon in a significant way, what’s the connection here? Dr. Greg Ruggerone walks us through how he has tried to answer this question and explains other biennial trends seen throughout marine ecosystems in the Pacific.
Dr. Greg Ruggerone is President of Natural Resources Consultants with over 35 years of experience studying salmon. His recent paper on possible interactions between pink salmon and killer whales caught the attention of the media earlier this year.
