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

这个美国-俄罗斯的论文研究项目是关于环类物种的分析。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“斯托尔比”国家自然保护区的根纳迪·v·凯尔伯格博士。PI和他的研究生计划在一个所谓的Phylloscopus环物种中调查物种限制的结构和动力学。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，来测试物种复合体是否真的是一个环状物种。他们还将通过回放实验和分析歌曲结构来研究生殖隔离。该项目对基因流动、局部适应和物种相互作用在物种形成中的作用具有普遍意义。更具体地说，它将评估在物种形成的初始阶段，地理变异在鸣声和鸣声识别中的作用。这个种群生物学研究项目实现了将美国和俄罗斯的顶尖专家聚集在一起的计划目标，在平等、互惠和互利的基础上，在共同感兴趣和能力强的领域结合互补的努力和能力。

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.
