Abstract

A review is given of the various botanical evidences for changes in vegetation cover of the Neotropics during the Pleistocene dry periods. Authors who have discussed vegetation changes in terms of plant geography are treated. There are considerable phytogeographic data which support the findings of palynology and geomorphology. The climate changes appear to have affected the vegetation of the entire neotropical region since evidence is presented from Mexico to Southern Brazil and from both the lowland and highland regions. The comparatively recent recognition of climatic and related vegetational changes have caused botanists to re-evaluate some of their earlier theories of speciation and biological diversity in the lowland tropics.
