Regulation of keystone predation by small changes in ocean temperature

  volume={283 5410},
Key species interactions that are sensitive to temperature may act as leverage points through which small changes in climate could generate large changes in natural communities. Field and laboratory experiments showed that a slight decrease in water temperature dramatically reduced the effects of a keystone predator, the sea star Pisaster ochraceus, on its principal prey. Ongoing changes in patterns of cold water upwelling, associated with El Nino events and longer term geophysical changes, may… CONTINUE READING
