Resistance of rocky intertidal communities to oceanic climate fluctuations

intertidal communities of Oregon and Northern California appear to have been broadly resis- tant to oceanic climate fluctuations over the past 14 years. Supporting information S1 Appendix.

(DOCX) Acknowledgments We thank the numerous technicians and students who performed the community surveys, including Roy Anderson, Silke Bachhuber, Allison Barner, Kris Bauer, Melissa Britsch, Jamie Canepa, Elizabeth Cerny-Chipman, Amanda Chiachi, John Dickens, Kamala Earl, Maya Fee- zell, Laurel Field, Emma Fraser, Heather Fulton-Bennett, Sean Garrity, Angela Johnson, Kailey Kraus, Chantelle MacAdams, Kinsey Matthews, Zech Meunier, Sydney Ngo, Skyler Peven, Megan Poole, Jerod Sapp, Haley Schmidt, Chenchen Shen, Seth Strumwasser, Barbara Spiecker, Jenna Sullivan-Stack, and Megan Urton. This research builds on studies begun by B. Menge, T. Gouhier, S. Hacker, F. Chan, and K. J. Nielsen. We thank Marti Anderson for a great PERMANOVA workshop where she helped us formulate our approach and Cristia´n Monaco for a helpful review. B. Menge conceived of the project and S. Gravem refined its scope. All authors collected the data and J. Robinson managed the data. S. Gravem and B. Poir- son performed the analyses. S. Gravem wrote the manuscript with editing by B. Menge. This is contribution number 536 by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO, www.PISCOweb.org). Author Contributions Conceptualization: Bruce A. Menge.
