(vii) THE ROLE OF CAIMANS IN THE NUTRIENT REGIME IN THE MOUTH-LAKES OF AMAZON AFFLUENTS.

This article provides a summary of the paper "The Role of Caimans in the Nutrient Regime in the Mouth-Lakes of Amazon Affluents" presented by E.-J. Fittkau at the Spring Meeting of the Tropical Group of the British Ecological Society held in London, England, on April 24, 1969. According to the paper, the formerly abundant caimans of the central Amazon region have nearly become extinct because of the demand for their hides. It highlights the existence of close interdependence between caimans and the fish in the Amazonian water-bodies.
