去年夏天，一种神秘的疾病开始在北美西海岸的海星中传播，影响范围比以往任何时候都更远，影响的物种也更多。类似的事情似乎也在东海岸发生。为了识别病原体，研究人员正在进行实验并寻找遗传线索。他们还在关注这些顶级掠食者的消失对生态的影响。
This past summer, a mysterious disease began to spread among sea stars on the west coast of North America, reaching farther and striking more species than ever before. Something similar seems to be happening on the east coast as well. To identify the pathogen, researchers are conducting experiments and searching for genetic clues. They are also watching for ecological impacts from the loss of these top predators.
