Marine organisms experience multiple stressors in their environment simultaneously, some of which are becoming more extreme with climate change. We analyzed the proteomic responses of gill tissue of the spider crab, Hyas araneus, and the intertidal porcelain crab, Petrolisthes cinctipes, to simultaneous emersion, pH, and temperature stress. The major proteomic changes indicate that gill responds in specific ways to all three stressors. The changes involve structural elements of the cuticle, protein maturation, ion transport, as well as nitrogen metabolism. The results provide insights into the complexity of the cellular response to multiple stressors and generate several novel hypotheses about how these stressors affect crustaceans.
