dc.description.abstractSexual dimorphism in dioecious plants is a common phenomenon that has received widespread attention, yet the implications for reproductive function and fitness remain poorly understood. Using data from a long term study of a population of 839 dioecious Iryanthera, hostmannii, (Myristicaceae 'nutmeg') trees in a large permanent plot in a lowland tropical rain forest, we examined the effects of greater investment in reproduction by females compared to males for various aspects of life history. Although male trees often produced more inflorescences than females, total dry mass of flowers was roughly equal in two out of three years for both sexes, implying that any investment differential lies in fruit production. There was no difference in the 125year relative growth rate of males and females, suggesting that females can compensate somehow for their greater reproductive investment, although there were weak suggestions that mortality might have been greater in females. Male flowers opened slightly earlier in the day than female flowers and were short lived, lasting at most two nights compared to up to four nights in females. Understanding the interacting effects of resource availability (studied here) and pollen movement (currently unknown in Iryanthera) on reproduction is essential in terms of life history theory. Knowledge of reproductive biology is key in considering the ecology and conservation of tropical forest communities.en_US
