Institute Publications

Rising seawater temperatures can increase the risk of disease outbreaks in many taxa. Pathogens are potentially the ultimate keystone species in that their small biomass can have massive impacts that ripple through ecosystems. Disease outbreaks can be particularly damaging when they affect ecosystem engineers, such as seagrasses. Outbreaks of wasting disease in seagrasses are one of a myriad of stressors associated with declining temperate and tropical seagrass meadows around the globe. Levels of eelgrass wasting disease are high in the San Juan Islands and Puget Sound. These increasing levels of disease are a threat to sustainability of eelgrass meadows, our …
