Última Heliconia acuminata reproductive success is independent of local floral density Acta Amazonica Bruna,Emilio M.; Kress,W. John; Marques,Francisco; Silva,Osmaildo Ferreira da. Reproductive plants in tropical forests are patchily distributed, with some in large aggregations of reproductive consepecifics while others are relatively isolated. This variation in floral density is hypothesized to have a major effect on plant reproductive success, since individuals in higher density neighborhoods can attract more or higher quality pollinators. We experimentally tested this hypothesis with populations of the understory herb Heliconia acuminata in central Amazonia. We created replicated plots in which reproductive plant density spanned the range of naturally occurring floral neighborhood size, then measured three surrogates of plant fitness in focal plants in each array. There was no significant difference between any of the three floral... Tipo: Info:eu-repo/semantics/article Palavras-chave: Phaethornis; Resource limitation; Pollinator limitation; Transplants.
