The research project examines how female swordtail fishes assess multiple male traits when choosing a mate. Female swordtail fish prefer vertical-bar pigment patterns that are symmetrical with many dark bars. The various components of this pigment pattern on males can be manipulated to determine if females from different species (1) have different preferences for the bars that could explain differences in the bar pattern across species, (2) prefer males with symmetrical bars because they are in better condition, and (3) have stronger preferences for components that provide better information about male condition. The educational plan is to develop an interactive Web page for Introduction to Zoology, increase opportunities for students to gain hands-on research experience, and expand collaborative interactions with Mexican colleagues where these fish are found.One of the more important decisions any animal makes is deciding with whom it will mate. Researchers are finding that, for a diverse group of organisms including humans, mate-choice decisions are based on multiple male traits, and yet we currently know very little about how multiple preferences interact. This research project will provide a more realistic view of the process of mate choice, while the educational plan will increase the interest of students from Ohio and Mexico in research.

该研究项目考察了雌性剑尾鱼在选择配偶时如何评估多种雄性特征。 雌性剑尾鱼更喜欢垂直的酒吧色素模式是对称的许多黑暗的酒吧。 雄性动物的这种色素图案的各种成分可以被操纵，以确定来自不同物种的雌性动物是否（1）对可以解释物种间条形图案差异的条形有不同的偏好，（2）更喜欢具有对称条形的雄性动物，因为它们处于更好的状态，以及（3）对提供更好的雄性状况信息的成分有更强的偏好。 教育计划是开发一个互动的网页，介绍动物学，增加机会，让学生获得实际的研究经验，并扩大与墨西哥同事的合作互动，在这些鱼的发现。任何动物作出的一个更重要的决定是决定与谁交配。 研究人员发现，对于包括人类在内的各种生物群体来说，择偶决定是基于多种男性特征的，但我们目前对多种偏好如何相互作用知之甚少。 这个研究项目将提供一个更现实的择偶过程的观点，而教育计划将增加来自俄亥俄州和墨西哥的学生对研究的兴趣。
