Abstract

Decma fissa is the most widely distributed species of the genus Decma occuring in southern China. This study presents the first phylogeographic work of D. fissa based on COI, Cytb and ITS sequence. We examined genetic diversity with ITS and mitochondrial sequence respectively, and phylogenetic work was based on the mitochondrial data. A high-level genetic diversity was revealed based on mitochondrial data but a low-level diversity was shown with ITS sequence. For the mitochondrial data, divergence time analysis displayed five lineages. Based on the Mantel test, geographic and genetic distances among D. fissa populations revealed a significant positive correlation. Bayesian skyline plot (BSP) analyses implied that none of three major lineages of D. fissa was seemingly affected by the last glacial maximum (LGM, 0.015-0.025 Mya). Ecological niche modeling was used to predict the distribution of D. fissa in four periods (LGM, Mid-Holocene, current and 2070) in China. Analysis of the ancestral area reconstruction indicated that D. fissa occurred in the South China area.

中国南方小蟋蟀Decma fissa的系统地理学和遗传结构(直翅目，蚱科)。

赤藓是赤藓属中分布最广的一种，产于中国南方。本文首次基于COI、Cytb和ITS序列进行了沙蚕的系统地理学研究。我们分别用ITS和线粒体序列检测遗传多样性，并基于线粒体数据进行系统发育工作。线粒体数据显示出高水平的遗传多样性，ITS序列显示出低水平的多样性。对于线粒体数据，发散时间分析显示了五个谱系。Mantel检验结果表明，不同居群间的地理距离和遗传距离呈显著正相关。贝叶斯天际线图(BSP)分析表明，三种主要系均未受到末次盛冰期(LGM, 0.015 ~ 0.025 Mya)的影响。利用生态位模型对中国4个时期(LGM、中全新世、当前和2070年)的沙蝇分布进行了预测。祖先区重建分析表明，裂裂裂齿出现在华南地区。
