Dispersal capacity and seed production in anemochorous plants

Summary Salisbury has argued that anemochory is less efficient than zoochory. His evidence indicates that zoochores produce fewer seeds and that far dispersing anemochores produce more seeds than do near dispersing anemochores. Limiting our discussion to the anemochore's part of the hypothesis, we reformulate Salisbury's measure of dispersal capacity into a more correct aerodynamic measure. This more correct equation does not support the relationship of increasing seed number per individual in further dispersing anemochores.
