Orca
If you want to know how healthy an ecosystem is, you need only look as far as the top predator. Dietmar Bago (Nadab, Romania) and Melanie Norman (Booragoon, Australia) will help Ken Balcomb and Dr. Astrid van Ginneken continue their long-term research on orca to put a finger on the pulse of ecosystem viability. Last year, resident orca whales in the southern Puget Sound in the state of Washington (USA) apparently stabilized their population size after nearly a decade of population decline. June 5-15
