Abstract
The dispersal mechanisms of 37 species of plants which occur on Amazonian white sand campinas were studied. 75.67 percent of the species have the potential for long distance diaspore dispersal, including 59.46 percent which are bird-dispersed. This dispersal disharmony towards long-distance dispersal and especially towards ornithochory is characteristic of islands in general. The campinas of the lower Rio Negro region of Amazonia may be treated biogeographically as islands surrounded by large areas of tropical rain forest. A total of eight dispersal types was observed and details of these mechanisms are presented. The type of germination of many of the species studied is reported for the first time.This publication has 1 reference indexed in Scilit:
