Die Allgemeine Lebensform des Erziehers,highly productive systems in waters which are otherwise low in nutrients and phytoplankton. Their complex, wave-resistant structures are built almost entirely by biological activity. The dominant reef-forming organisms are the scleractinian ( = stony) corals which grow by means of an accretionary ex

Two of the most characteristic coastal communities of this nature are saltmarshes, which are found mainly in temperate to subpolar climates, and mangrove swamps which are of tropical to subtropical occurrence (Figure 7

The animals so far neglected include fish, birds and mammals including man. This chapter considers some of our ‘remaindered’ habitats.
