Resumen
Descripción
This study explicitly examines reproductive phenology and seed production as influenced by multiple interacting factors across scales. We predicted that: (1) climatic cues would be most important in determining population level phenology and seed production due to potential for large-scale resource limitation;(2) seed production would be significantly higher in occasionally inundated forests based on previous research indicating species preference for swamp forest; (3) tree attributes such as diameter and liana load would be strongly implicated in determining individual seed production potential and would be consistent across forest types. We chose Carapa guianensis as a model species because it is a tropical tree that demonstrates pronounced temporal variability in seed production.
