Development of a Microsatellite Gene Library for Sceloporus grammicus (Squamata, Phrynosomatidae), and a Preliminary Assessment of Male Mating Success in the Tulancingo Hybrid Zone

项目编号：9900975PI: Elisabeth Arevalo HolderTitle：建立grammicus（鳞目，狐尾虫科）微卫星基因库，并初步评估图兰ingo杂交区雄性交配成功率。狐尾虫是生态学、行为学和种群遗传学研究的良好模型系统。由至少8个不同的染色体种族组成的遗传变异物种Sceloporus grammicus复合体为这类研究提供了独特的资源。本项目旨在开发葡萄球菌复合体个体和群体的遗传特征标记。这些标记将用于检查各种基本问题。这一群体的交配系统将被描述，雌性和领地雄性的繁殖成功率将被评估。这将有可能比较来自单一染色体种族的雄性和杂交雄性的领地大小。该研究将为杂交带的维持和物种形成过程提供基础信息。它综合了有机体和人口两级的分析，对生殖成功的行为组成部分和随后在人口一级的后果采取了综合办法。此外，它还将促进普罗维登斯学院和墨西哥大学之间的合作。

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.
