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

INT 97-24817普莱斯这个美俄学位论文研究项目是对一种环状物种的分析。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”国家级自然保护区的根纳季·V·凯尔伯格博士。皮尔和他的研究生计划研究一种所谓的竹环类物种的物种限制的结构和动态。他们将通过在整个复合体的不同位置采集血液样本来研究遗传变异的模式，以测试物种复合体是否真的是环状物种。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、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，它将评估地理变异在歌曲和歌曲识别中的作用，以及物种形成的初始阶段。这一人口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，在平等、互惠和互利的基础上，在共同利益和能力强的领域结合互补努力和能力的计划目标。

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.
