Fruit phenology observations and consumption of Dimorphandra mollis (Leguminosae) were analyzed during seven months in an area of cerrado stricto sensu. We analysed 81 fecal samples collected at six different places of lowland tapirs (Tapirus terrestris) in central Brazilian cerrado. In addition, from the feces of five tapirs at the Brasília Zoo to which fruit had been offered, seeds were collected and used in germination tests. The results suggest that the tapir is an important fruit consumer and a potential seed disperser of D. mollis. In the field, however, fruit consumption was found to be very low, probably because of both fruit palatability and the low density of frugivores, especially tapirs. The possibility that the original dispersal agents of D. mollis seeds belonged to the South American Pleistocene megafauna is discussed.
在严格意义上的塞拉多地区,对柔毛孪叶豆(豆科)的果实物候观测和消耗量进行了为期七个月的分析。我们分析了在巴西中部塞拉多低地貘(南美貘)六个不同地点采集的81份粪便样本。此外,从巴西利亚动物园五只投喂过水果的貘的粪便中收集种子,并用于发芽试验。结果表明,貘是柔毛孪叶豆重要的果实消费者和潜在的种子传播者。然而,在野外发现果实消耗量非常低,这可能是由于果实的适口性以及食果动物,尤其是貘的低密度所致。文中还讨论了柔毛孪叶豆种子最初的传播媒介属于南美洲更新世巨型动物群的可能性。
