Integrating the effects of climate and seed fall velocities on seed dispersal by wind: A model and application

A numerical model of seed dispersal by wind is presented which integrates the effects of wind speeds and directions during seed dispersal season, height of seed release, seed terminal velocities and effects of wind speed/atmospheric humidity on seed release rates. A histogram of terminal velocities...

Summary:A numerical model of seed dispersal by wind is presented which integrates the effects of wind speeds and directions during seed dispersal season, height of seed release, seed terminal velocities and effects of wind speed/atmospheric humidity on seed release rates. A histogram of terminal velocities of maple ( Acer spp.) seeds and climatic data of Minneapolis, MN, are used to derive a seed dispersal pattern for an isolated tree. Under these conditions seed dispersal is asymmetric around the seed source. Maximum seed deposition occurs 100 m northeast of the seed source (13 seeds m −2 per 10 6 seeds released); this declines to 1 seed m −2 at 300 m and 0.03 seeds m −2 at 600 m distance from the seed source.
