Contribution of Vouacapoua americana fruit-fall to the release of biomass in a lowland Amazon forest

Abstract Fruit-fall provides the transfer of biomass and nutrients between forest strata and remains a poorly understood component of Amazon forest systems. Here we detail fruit-fall patterns including those of Vouacapoua americana a Critically Endangered timber species across 25 km2 of lowland Amaz...
