Dissertation Enhancement: Impacts of a migratory detritivorous fish on nitrogen cycling in a tropical stream

这篇论文增强补助金支持布拉德利泰勒的方向下，罗伯特O。霍尔的怀俄明州大学，研究在委内瑞拉的热带流中的氮循环的一种洄游性食虫鱼的影响。该奖项支持在整合单一鱼类对氮循环多个组成部分的影响方面的新颖研究。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。虽然植物类群的物种多样性与生态系统功能之间的关系已引起人们的广泛关注，但我们对动物如何影响生态系统功能的认识仍处于初级阶段。（Prochilodus mariae），这是一个潜在的强大的相互作用在热带安第斯溪流，并建立在以前的工作，以测试是否这个单一的物种影响流氮循环，生态系统功能的基本组成部分。

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.
