RPG: Genetic and Behavioral Analysis of an Avian Social System

9407310约翰逊摘要动物交配系统是进化生物学的中心话题，因为交配模式可以极大地影响种群的进化速度和路径。分子生物学的最新进展表明，鸟类的交配系统并不总是像它们看起来的那样：例如，许多长期以来被认为是忠实的一夫一妻制的物种，实际上是相当混杂的。约翰逊博士将描述一群大尾巴幼虫的社会交配系统(行为)，使用DNA微卫星来描述遗传交配系统(亲子关系)，并测试现有的关于一夫多妻制交配系统进化的假设。

9407310 Johnson ABSTRACT Animal mating systems are a central topic in evolutionary biology, because mating patterns can greatly affect the speed and path of evolution in a population. Recent advances in molecular biology have revealed that avian mating systems are not always as they appear: for example, many species long thought to be faithfully monogamous are actually quite promiscuous. Dr. Johnson will describe the social mating system (behavior) in a colony of Great-Tailed Grackles, use DNA microsatellites to characterize the genetic mating system (parentage), and test existing hypotheses for the evolution of polygynous mating systems.
