Reproductive Synchrony of a Tropical Shrub: Experimental Studies on Effects of Pollinators and Seed Predators in Hybanthus Prunifolius (Violaceae)

摘要: This study compares reproductive success of individual plants flowering and fruiting in an out synchrony with the population. I test hypotheses that enhances a plant's ability to: (1) attract pollinators, (2) avoid seed predators. The prediction is its population has higher fruit ovule set after pollination more seeds at dispersal time than synchrony. species Hybanthus prunifolius (Schult.)
