In this paper we test two simple hypotheses: (1) that -diversity has a stronger influence than - diversity on pollen spectra.
Hypothesis 1: -diversity has a stronger influence than -diversity on pollen spectra.
Above 3900 m, subp'ramo shrub taxa a decreased and the pollen spectra reflect the grass p'ramo belt.
Within the forested zone long-distance pollen dispersal is of rather small i mportance, and t he downslope limit of forest taxa was reflected accurately in pollen spectra.
Within the tropical lowlands where pollen spectra from specific community types have been identified, a few key indicator taxa have lain at the heart of the statistical separations.
