Patterns of Ant-mediated Pollen Dispersal in Diamorpha smallii (Crassulaceae)

Abstract
Gene flow distances in Diamorpha smallii (Crassulaceae) effected through pollen dispersal by ants (Formica schaufussi and F. subsericea) are extremely short and their frequency distributions are strongly leptokurtic in form. Increased plant density is associated with decreased pollen dispersal distances. This pattern of pollen dispersal may explain earlier electrophoretic data indicating a highly subdivided population structure in D. smallii.
