%X A micrometeorological model was derived for the dispersal of winged
or plumed seeds from a point source, based on mean release height,
mean and standard deviation of the terminal velocities of seeds,
standard deviation of vertical wind velocities, and the mean and
standard deviation of the natural logarithms of horizontal wind
velocities. Predictions include 1) the distribution of the dispersal
curve (defined as numbers vs. distance from source) is right skewed;
2) the median and long-range dispersal distances need not be well
correlated; and 3) increased variance in flight trajectories for
a seed population will place the mode of the dispersal curve closer
to the source. Winged seeds do not detach from the parent randomly
with respect to horizontal wind velocity. -from Authors
