Sexes show contrasting patterns of leaf and crown carbon gain in a dioecious rainforest shrub

Nicotra, Adrienne; Chazdon, Robin; Montgomery, Rebecca


The sexes of dioecious species may differ in a range of vegetative and reproductive traits as well as in physiological traits. In Siparuna grandiflora, a Neotropical dioecious shrub, we examined differences in leaf-level photosynthesis of different classes of leaf age and, using simulation models, explored whether differences in leaf-level carbon gain led to sex differences in whole-plant daily carbon gain. Male plants had higher photosynthetic capacity at the leaf level. As leaves of both...[Show more]
