A translated, thoroughly revised, and updated edition of the German work. Part I presents the geographic distribution of seaweeds and seagrasses around the world, environmental factors, floral history, and relevant paleoceanographic considerations, covered geographically. Part II covers seaweed ecophysiology, including the relationships of light, temperature, salinity, and other abiotic factors on seaweed distribution, as well as biotic factors such as competition, herbivory, predation, and parasitism, in order to elucidate the ecophysiologic bases for the distribution patterns examined in Part I.
