Our 2016 article “Killer whale miscarriages linked to low food supply” provided an early look at a study published this week in the journal PLOS ONE.
PSI senior writer Christopher Dunagan wrote the article based on research that was presented at the 2016 Salish Sea Ecosystem Conference, and it remains a helpful summary of the newly published findings.
Scientists have found that Puget Sound’s endangered Southern Resident Killer Whales are experiencing a high rate of miscarriages in large part because they are not getting enough food. The whales depend primarily on diminished populations of Chinook salmon and this scarcity magnifies other existing threats ranging from toxic PCBs to noise pollution.
The PLOS ONE study was co-authored by Samuel K. Wasser , Jessica I. Lundin, Katherine Ayres, Elizabeth Seely, Deborah Giles, Kenneth Balcomb, Jennifer Hempelmann, Kim Parsons, and Rebecca Booth. Dunagan’s article summarizing their findings is available on the Encyclopedia of Puget Sound.
