Animal Behavior ProgramNontechnical AbstractProposal #: 9900975PI: Elisabeth Arevalo HolderTitle: Development of a microsatellite gene library for Sceloporus grammicus (Squamata, Phrynosomatidae), and a preliminary assessment of male mating success in the Tulancingo hybrid zoneLizards are an excellent model system for ecological, behavioral and population genetic studies. The genetically variable species Sceloporus grammicus complex, consisting of at least eight different chromosomal races, provides a unique resource for such studies. This project is aimed at developing markers for genetic characterization of individuals and populations in the S. grammicus complex. These markers will be used to examine a variety of basic questions. The mating system of this group will be characterized and the reproductive success of females and territorial males will be assessed. It will be possible to compare the territory sizes of males from a single chromosomal race versus that of males that are hybrids. This research will provide basic information concerning the maintenance of hybrid zones and the process of speciation. It integrates across the organismal and population levels of analysis and constitutes an integrated approach to behavioral components of reproductive success and subsequent population level consequences. In addition, it will foster collaboration between Providence College and the University of Mexico.

动物行为计划非技术摘要提案编号：9900975PI：Elisabeth Arevalo Holder标题：开发 Sceloporus grammicus（Squamata、Phrynosomatidae）微卫星基因库，并对图兰辛戈杂交区雄性交配成功率进行初步评估蜥蜴是生态、行为和群体遗传学研究。 遗传变异物种 Sceloporus grammicus 复合体由至少八个不同的染色体种族组成，为此类研究提供了独特的资源。 该项目旨在开发用于 S. grammicus 复合体中个体和种群遗传特征的标记。 这些标记将用于检查各种基本问题。 该群体的交配系统将被表征，雌性和领地雄性的繁殖成功率将被评估。 将有可能比较来自单一染色体种族的雄性与杂种雄性的领地大小。 这项研究将提供有关混合区维持和物种形成过程的基本信息。 它整合了有机体和种群水平的分析，并构成了生殖成功的行为组成部分和随后的种群水平后果的综合方法。 此外，它将促进普罗维登斯学院和墨西哥大学之间的合作。
