Tidepools and rocky shores are among the most physically stressful environments on earth. When the tide is high, waves can sweep over plants and animals at velocities as high as 60 miles per hour, while at low tide, the same organisms dry up and bake in the sun. Yet despite this seeming inhospitality, tidepools and rocky shores are exceptionally complex and biologically diverse. This comprehensive encyclopedia is an authoritative, one-stop reference for everyone interested in the biology and ecology of this fascinating and uniquely accessible environment. Conveniently arranged alphabetically, nearly 200 wide-ranging entries written in clear language by scientists from around the world provide a state-of-the-art picture of tidepools and rocky shore science. From Abalones, Barnacles, and Climate Change through Seagrasses, Tides, and Wind, the articles discuss the animals and plants that live in tidepools, the physics and chemistry of the rocky shore environment, the ecological principles that govern tidepools, and many other interdisciplinary topics. * Generously illustrated with hundreds of color photographs, drawings, and diagrams * The only comprehensive volume available on tidepools and rocky shores * Articles include in-depth looks at animal and algal diversity and overviews of the history of research, rocky shore management, and conservation * Contributors are experts on physics and physical oceanography, experimental ecology, population genetics, taxonomy, and other disciplines
