When streams in tropical rain forests flood, their fish populations often swim into the adjacent forests, in some cases for dozens of miles. Fish species that feed on tropical fruits may then disperse seeds over large areas beyond the normal stream boundaries. Previous studies have revealed that fish of the genus Brycon are major components of this seed dispersal system. Accordingly, the P.I. proposes to investigate the diet of Brycon, and particularly the use of figs, and the nature and degree of seed dispersal into forest next to tropical streams in Costa Rica. The study will provide important insights into an unknown component of the maintenance of tree diversity and community structure in tropical rain forests.

当热带雨林中的溪流泛滥时，它们的鱼群经常游到邻近的森林里，有时游到几十英里外。以热带水果为食的鱼类可能会将种子传播到超出正常溪流边界的大片地区。以前的研究表明，Brycon属的鱼类是这个种子传播系统的主要组成部分。因此，P.I.建议调查Brycon的饮食，特别是无花果的使用，以及种子传播到哥斯达黎加热带溪流旁森林的性质和程度。这项研究将为热带雨林中树木多样性和群落结构维持的未知组成部分提供重要见解。
