| Abstract |
Features of the intertidal zonation on the rocky shores of the Galapagos Islands are described and discussed in relation to environmental factors, in particular temp -which varies with regional hydrology and climatology. Owing the thermal properties of the coastal waters and to the nature of the substrate (mainly basalt), intertidal organisms are exposed to a wide range of temps, which fluctuate with tide, day, and season. As a result, life is mostly restricted to the lowest levels of the shore; the middle-and upper-level populations are sparse. Local variations (biofacies) resulting from water agitation are described. Biota consist of tropical, subtropical, and warm-temperate components. Tropical spp dominate in sheltered areas and in middle and upper shores. |
