Disease as an ecological force
Are diseases playing a role in salmon decline?
Chinook, coho and steelhead populations in Puget Sound have declined dramatically over the past 30 years. In some cases, counts of fish returning to the rivers are just a tenth what they were in the 1980s. While many possible causes of this decline are under consideration, some researchers are focusing on the combined effects of predators and disease. This article continues our coverage of the ecological impacts of disease in Puget Sound.
Going viral: Concerns rise over potential impacts of disease on the ecosystem
Recent high-profile sewage spills into Puget Sound could mean more pathogens in the environment, prompting us to re-publish this story from 2016. From orcas to starfish to humans, disease affects every living creature in the ecosystem. Scientists are increasingly alarmed by its potential to devastate already compromised populations of species in Puget Sound.
