This dissertation enhancement grant supports Bradley Taylor under the direction of Robert O. Hall of the University of Wyoming to study the impacts of a migratory detrivorous fish on nitrogen cycling in a tropical stream in Venezuela. This award supports research that is novel in integrating the impacts of a single fish species on multiple components of the nitrogen cycle. Ecologists are fundamentally interested in the degree to which organisms influence ecosystem structure and function. Although much attention has focused on the relationship between species diversity and ecosystem function for plant taxa, our understanding of how animals influence ecosystem function is still in its infancy.This proposal focuses on migratory fish (Prochilodus mariae) that is a potentially strong interactor in tropical Andean streams and builds on previous work to test whether this single species affects the stream nitrogen cycle, a fundamental component of ecosystem function.

这笔论文增强资助支持布拉德利·泰勒在怀俄明大学罗伯特·O·霍尔的指导下研究迁徙的食性鱼类对委内瑞拉热带溪流中氮循环的影响。该奖项支持整合单一鱼类对氮循环多个组成部分影响的新颖研究。生态学家从根本上对生物体影响生态系统结构和功能的程度感兴趣。尽管人们对植物类群的物种多样性与生态系统功能之间的关系给予了很多关注，但我们对动物如何影响生态系统功能的理解仍处于起步阶段。该提案重点关注洄游鱼类（Prochilodus mariae），它是热带安第斯溪流中潜在的强相互作用者，并建立在之前的工作基础上，测试该单一物种是否影响溪流氮循环，这是生态系统功能的基本组成部分。
