This study will examine the physiological and evolutionary responses to the Gulf of Mexico oil leak of a small crustacean, the copepod Eurytemora affinis. This species is a dominant member of coastal ecosystems, especially those in the Gulf of Mexico. This project will address the following questions: (1) How quickly and to what extent can organisms evolve in response to the toxic effects of crude oil? (2) Which traits evolve in response to crude oil exposure? (3) Do different populations (independently-derived selected lines, and populations from different locations in the field) respond in a similar manner? (4) Is there a cost to adaptation to the toxic effects of crude oil? It will accomplish these goals by conducting a laboratory selection and comparing those reponses to evolutionary changes in Gulf populations.Understanding evolutionary responses is essential for determining the long-term survival and recovery of the impacted populations, given the acute toxicity of crude oil. Beyond the copepods, the results of this study will provide critical information for understanding responses in other gulf species. The project will also result in the training of two graduate students.

这项研究将考察墨西哥湾漏油事件对一种小型甲壳类动物Eurytemora affinis的生理和进化反应。该物种是沿海生态系统的优势成员，特别是墨西哥湾的沿海生态系统。该项目将解决以下问题：(1)生物进化对原油毒性影响的反应有多快，程度有多大？(2)对原油暴露的反应有哪些特征？(3)不同的种群(独立衍生的选育品系，以及来自田间不同地点的种群)是否以相似的方式作出反应？(4)适应原油毒性效应是否有成本？它将通过进行实验室选择并比较这些对墨西哥湾种群进化变化的反应来实现这些目标。鉴于原油的急性毒性，了解进化反应对于确定受影响种群的长期生存和恢复至关重要。除了桡足类，这项研究的结果将为理解其他海湾物种的反应提供关键信息。该项目还将培训两名研究生。
