Analysis of biogeographic patterns in the Holarctic via comparative molecular phylogenetics of dispersal-limited harvestmen (Arachnida: Opiliones)

在本项目的范围内，将一组扩散能力差的动物的分子进化与北方（泛北极）的地质历史情景进行了比较。我的目标是将新的生物学方法应用于过时的分子生物学，以明确地测试关于地球上最大的动物地理区域内多样性和分布原因的不同假设。陆生收割者（蛛形纲：Opiliones）是模式类群，在南方苗族的地理研究中已被证明是有价值的。分子系统发生学将使用几个标记来重建，以确定系统分类目的的自然（单系）组，并概述它们作为离散的单位，为植物地理学的目的。测序和系统分类的准备工作将在几个合作项目中分配，其中地理学项目是中央协调机构。该项目促进了申请人科学发展的稳定，跨学科和国际网络的建立。

Within the scope of the presented project is the comparison of the molecular evolu-tion of a group of animals with poor dispersal abilities with scenarios of the geological history of the northern hemisphere (Holarctic). My objective is to apply novel statistic-al methods to dated molecular phylogenies to explicitly test different hypotheses about causes of diversity and distribution within the largest zoogeographic realm on Earth. Terrestrial harvestmen (Arachnida: Opiliones) are featured as model taxa, which have already proved valuable in biogeographical studies of the southern he-misphere. Molecular phylogenies will be reconstructed using several markers to de-fine natural (monophyletic) groups for systematic-taxonomic purposes, and to outline them as discrete units for biogeographic purposes. Sequencing and systematic-taxonomic preparations will be distributed among several collaborations, for which the biogeographic project represents the central coordinating body. This project pro-motes the establishment of a stable, interdisciplinary and international network for the scientific development of the applicant.
