A major concern in conservation biology is the effects of invasive species that cause aesthetic, cultural, economic, and ecological disasters. Species invasions are prevalent in aquatic systems; for example, fish communities have been intensively altered due to intentional and accidental introductions. A key objective is to understand how effects of invasive species impact native species and alter ecosystem processes. This research will explore the influence of an invasive fish, common carp (Cyprinus carpio), on ecosystem dynamics at multiple spatial scales of mesocosms and lakes. The hypothesis to be explored is that the impact of an invasive species will vary with native species richness. Understanding the ability of native biodiversity to buffer the effects of invasive species is important as local biodiversity represents an important line of defense against the spread of invaders and is a strong determinant of ecosystem processes.This study will provide insights into basic ecological processes by linking changes in biodiversity to ecosystem processes. The results of this study will also improve predictions of invasive species effects allowing informed, integrated management decisions for conservation. In addition, this project will provide opportunities for undergraduate training in field and laboratory techniques associated with research in aquatic ecology.

保护生物学中的一个主要问题是造成美学、文化、经济和生态灾难的入侵物种的影响。物种入侵在水生系统中很普遍；例如，由于故意和意外的引入，鱼类群落发生了强烈的变化。一个关键目标是了解入侵物种的影响如何影响本地物种和改变生态系统过程。本研究将探讨入侵鱼类鲤鱼(Cyprinus Carpio)在中尺度和湖泊多个空间尺度上对生态系统动力学的影响。有待探索的假设是，入侵物种的影响将随本地物种的丰富度而变化。了解本地生物多样性缓冲入侵物种影响的能力很重要，因为当地生物多样性是抵御入侵者扩散的重要防线，也是生态系统过程的强大决定因素。这项研究将通过将生物多样性的变化与生态系统过程联系起来，提供对基本生态过程的洞察。这项研究的结果还将改善对入侵物种影响的预测，从而为保护做出知情的综合管理决策。此外，该项目将为本科生提供与水生生态学研究相关的野外和实验室技术方面的培训机会。
