title: Biomass and nutrient allocation in a neotropical dioecious palm.
abstract: The sexes of Chamaedorea ernesti-augusti are largely undifferentiated in the distribution of biomass, nitrogen, phosphorus, potassium, and total non-structural carbohydrates, among leaves and stems. Males bear more inflorescences that are cheaper except in nitrogen, but most females bear greater annual energetic and nutritional burdens due to seed production. The ratio of vegetative to reproductive biomass is 3.5 for males but only 1.2 for females on a per module basis.
