Animals communicate with each other using specific behaviors that are controlled by the interaction of muscles, hormones, and the central nervous system. However, it is not yet known whether species that exhibit the same patterns of behavior have similar muscular, hormonal, and neural traits (collectively referred to as mechanisms of behavior), or if different combinations of these traits can produce the same behaviors. This project uses a group of 26 lizard species in the genus Anolis to determine the mechanisms that underlie two social behaviors: communication with other lizards through the extension of a throat fan, and copulation. Because these behaviors are simple, but can be directly compared across multiple species, this study allows a clear and comprehensive assessment of the interactions between the neuromuscular traits that control behavior in all vertebrates. This study is comprised of two components, both of which aim to determine the evolutionary relationships between social behaviors and their mechanisms. First, by combining detailed observations of the animals' natural behavior with biochemical assays that measure the neuromuscular traits of the animals, this project will determine if species that live in similar habitats have similar behaviors and their underlying mechanisms, and if species in different habitats exhibit different behaviors and behavioral mechanisms. Next, a laboratory experiment will manipulate rates of social behavior in males of four species by altering their levels of testosterone. This experiment will determine whether hormone-enhanced behaviors are associated with the same combination of neuromuscular traits across species. Overall, this project will provide intensive, hands-on research experiences for 12 undergraduate students, and will form the basis of a program for fifth grade science teachers and their students in urban public schools in San Antonio. These efforts will focus on providing accessible training in the science of behavior and physiology to a diverse community.Data will be made available: EthoBank (http://www.indiana.edu/~ethobank/index.html) and lizardbase(http://lizardbase.org/pages/index.html)

动物使用特定的行为相互交流，这些行为是由肌肉，激素和中枢神经系统相互作用控制的。但是，尚不清楚表现出相同行为模式的物种是否具有相似的肌肉，荷尔蒙和神经性状（统称为行为机制），或者这些特征的不同组合是否会产生相同的行为。该项目使用Anolis属中的26种蜥蜴物种来确定基于两种社会行为的机制：通过扩展喉咙风扇与其他蜥蜴的交流和交配。由于这些行为很简单，但可以在多种物种之间直接进行比较，因此该研究允许对控制所有脊椎动物的行为的神经肌肉性状之间的相互作用进行清晰而全面的评估。这项研究由两个组成部分组成，这两种组成部分旨在确定社会行为及其机制之间的进化关系。首先，通过将动物自然行为的详细观察与测量动物神经肌肉性状的生化测定相结合，该项目将确定生活在相似栖息地的物种是否具有相似的行为及其潜在机制，以及在不同栖息地中的物种是否表现出不同的行为和行为机制。接下来，实验室实验将通过改变其睾丸激素水平来操纵四种男性的社会行为率。该实验将确定激素增强的行为是否与跨物种的神经肌肉性状相同。总体而言，该项目将为12名本科生提供密集的，动手的研究经验，并将为圣安东尼奥市城市公立学校的五年级科学教师及其学生构成计划。这些努力将着重于为多元化的社区提供可访问的行为和生理科学培训。Data将提供：Ethobank（http://wwwwwww.indiana.edu/~ethobank/index.html）和lizardbase（http://lizardbase.orgase.org/pages/pages/index.html）
