Pollen representation, source area, and basin size: toward a unified theory of pollen analysis

Auteur :
PRENTICE, J. C.

Description :
The concepts of pollen source area and of production and dispersal biases in pollen representation are quantified by means of a simple theoretical model. Source areas and relative pollen representation are shown to depend on basin size according to functions that describe the amount of pollen remaining airborne at increasing distances from single pollen sources. The integrated form of Sutton's equation for particle dispersal from a ground-level source gives usefull approximations applicable to pollen transport over a forest canopy. Results of simulations using this equation are given.
