   abstract = {A highly variable fraction of final-sized fruits (on average, 80.1% and 55.5% in consecutive study years) contained empty seeds, either because of embryo abortion or parthenocarpy, but these fruits were retained and eventually consumed by birds. A total of 26 bird species consumed the fruits, with 19 being seed dispersers accounting for the removal of 82.5% and 83.3% of the final-sized fruit crop in 2 study years. Only 4 bird species removed 82.2% of the seeds and pulp/seed predators took 6.0%. Plant characteristics directly related to fecundity had strong effects on estimates of dispersal success relevant to finess, accounting for 82.4% of its variance when holding constant the effects of fruit-design traits; the latter accounted for 1.8% of this variance. Fruit removal by frugivores had a negligible contribution to variation in realized reproductive output, largely attributable to the cumulative effects of the pre-dispersal phase, when great losses of potential fecundity occurred as abortion of embryos or production of parthenocarpic fruit. -from Author},
