U.S.-Russian/Kazakhstan Dissertation Research: Analysis of A Ring Species

INT 97-24817价格 这个美国-俄罗斯的博士论文研究项目是关于一个环物种的分析。主要研究人员是加州大学圣地亚哥分校的特雷弗普莱斯博士和他的研究生达伦欧文，以及俄罗斯克拉斯诺亚尔斯克的“斯托尔比”国家自然保护区的根纳季V.凯尔伯格博士。 PI和他的研究生计划调查一个所谓的Phylloscopus环物种的结构和物种限制的动态。 他们将通过在整个复合体的不同位置收集血液样本来研究遗传变异的模式，以测试该物种复合体是否真的是一个环形物种。 他们还将通过播放实验和分析歌曲结构来研究生殖隔离。 该项目对基因流、局部适应和物种形成中的物种相互作用的作用具有普遍意义。 更具体地说，它将评估地理变化在歌曲和歌曲识别的物种形成的初始阶段的作用。 这个种群生物学研究项目实现了将美国和俄罗斯的领先专家聚集在一起的计划目标，在平等，互惠和互利的基础上，在具有强烈共同利益和能力的领域联合收割机互补努力和能力。

INT 97-24817 Price This U.S.-Russian dissertation research project is on the analysis of a ring species.The principal investigators are Dr. Trevor Price and his graduate student, Darren Irwin, of the University of California, San Diego and Dr. Gennady V. Kelberg of the "Stolbi" National Nature Reserve in Krasnoyarsk, Russia. The PI and his graduate student plan to investigate the structure and dynamics of species limits in a purported Phylloscopus ring species. They will test whether the species complex is truly a ring species by collecting blood samples at various locations throughout the complex to study patterns of genetic variation. They will also investigate reproductive isolation by using playback experiments and analyzing song structures. The project has general implications for the role of gene flow, local adaptation, and species interactions in species formation. More specifically, it will evaluate the role of geographical variation in song and song recognition during the initial stages of speciation. This project in population biology research fulfills the program objectives of bringing together leading experts in the U.S. and Russia to combine complementary efforts and capabilities in areas of strong mutual interest and competence on the basis of equality, reciprocity, and mutuality of benefit.
