Aspects écologiques de la zonation intertidale sur les côtes rocheuses des Îles Galapagos / G.T. Houvenaghel et N. Houvenaghel. - 1974. - 135-152 p.
Features of the intertidal zonation on the rocky shores of the Galapagos Islands are described and discussed in relation to environmental factors, in particular temperature — which varies with regional hydrology and climatology. Owing to 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 temperatures, 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 species dominate in sheltered areas and in middle and upper shores.
