Relationships between breeding and spatial pattern in some dioecious tropical rainforest trees

Abstract

The process of pollen movement between the population members of three species of insect pollinated dioecious trees is examined in northern Australian tropical rainforests. Flowering patterns, fruit production, pollinator periodicities and efficiences and the quantities of pollen transferred to pistillate trees are described. Ways in which the distance between staminate and pistillate trees affects pollen capture and fecundity in pistillate trees are analysed.
