PISCO researchers at Stanford University have found that certain species of barnacles use heat shock protein 70 as a "preparative defense" strategy, maintaining high levels of Hsp70 in their cells as a mechanism for protection against periods of extreme and unpredictable heat stress. Barnacles are a key animal in the intertidal both as a source of prey and a source of larvae which are an important food source in the near shore pelagic environment. This research has important implications to predict the response of these animals to changing climatic conditions and provide managers information about the reaction of the environment to climate change and allow preparative strategies to be developed.
