RII Track-4: Enhancement of technical and analytical skills for the application of genomics to research in molecular ecology and comparative phylogeography

非技术性描述：由于气候变化，生物多样性或生态系统中物种的多样性在世界许多地区正在下降。生态系统如何应对不断变化的环境条件，包括不断变化的气候，以及生物多样性如何受到大规模环境变化的影响，这些问题仍然没有得到解答。这项研究金将使研究利用遗传技术来研究生物体如何应对过去和最近的环境变化。PI将与俄亥俄州州立大学的同事合作，了解在阿巴拉契亚南部森林中发现的四种无脊椎动物物种的数量和遗传变异性如何随着环境的变化而变化。PI获得的新技能将为研究员，家乡机构（密西西比大学）和家乡提供长期利益。研究金还将为与东道机构（俄亥俄州州立大学）的持续合作创造新的机会。研究结果将促进对整个社区是否有能力共同应对环境变化的理解，或者作为单个物种。这些信息将有助于保护和管理美国森林fause.Technical描述：了解不同的历史事件和经常性的微进化过程的影响如何共同分布的物种表现出一致的与独立的响应环境变化允许更强的预测生态群落将如何应对未来的变化。这种比较的方法可以探测物种之间的生态共同协会的力量，在限制或促进他们的反应的重要性。作为该奖学金的一部分，人口基因组数据将生成和分析一组四个南部阿巴拉契亚森林无脊椎动物物种，共同使生态协同作用的强度的影响对地理一致性进行评估。主办机构（俄亥俄州州立大学）将与PI合作，对简化代表性文库进行测序，采用计算方法进行下游生物信息学处理，并实施已建立和新出现的生物地理学分析。PI和主机还将合作开发分析，扩展比较地理推断的范围。

Non-technical description:Biodiversity, or the variety of species in an ecosystem, is declining in many areas of the world due to climate change. Many unanswered questions remain as to how ecosystems respond to changing environmental conditions, including changing climates, and how biodiversity is affected by large scale environmental changes. This fellowship will enable research using genetic techniques to study how organisms have responded to past and recent environmental change. The PI will collaborate with colleagues at the Ohio State University to understand how the numbers and genetic variability of four invertebrate species found in southern Appalachian forests change as their environment changes. The new skills gained by the PI will provide long-term benefits to the fellow, the home institution (University of Mississippi), and home state. The fellowship will also generate new opportunities for sustained collaboration with the host institution (Ohio State University). Findings will advance understanding of whether whole communities have the ability to respond to environmental change together, or as individual species. This information will aid in conservation and management of US forest fauna.Technical description:Understanding the impact of different historical events and recurrent microevolutionary processes on how co-distributed species show concerted versus independent responses to environmental change allows stronger predictions about how ecological communities will respond to future change. Such a comparative approach can probe the importance of the strength of ecological co-associations among species in constraining or facilitating their responses. As part of this fellowship, population genomic data will be generated and analyzed for a set of four southern Appalachian forest invertebrate species that together enable the impact of strength of ecological co-association on phylogeographic congruence to be assessed. The host institution (Ohio State University) will work with the PI in sequencing reduced representation libraries, computational approaches for performing downstream bioinformatics processing, and implementation of established and emerging phylogeographic analyses. The PI and host will also collaborate on developing analyses that extend the scope of comparative phylogeographic inference.
