摘要:

我们用特有性简约性分析方法对中国蚱科昆虫分布格局和各分布区之间的关系进行了探讨。根据蚱科昆虫的分布, 构建特有性简约性分析所需的矩阵, 以东北区作为外群, 用最大简约法通过穷尽式搜索得到分布区分支图。分布区分支图上8大生物地理分布区可分成4个聚类群: 第一个聚类群是东北区; 第二个聚类群是蒙新区; 华中区、华东区及华北区组成第三个聚类群; 华南区、西南区及青藏区则组成第四个聚类群。分布区分支图表明东北区与蒙新区比其他生物地理分布区形成要早, 其原因我们推测可能与更新世的冰川活动有关。总体上来说, 中国蚱科昆虫生物多样性南部比北部丰富, 我们认为可从两方面来解释, 一是更新世森林避难所的形成, 二是生态环境的恶化。

Abstract

We studied patterns of distribution and relationships among distributional areas of Tetrigidae insects in China using parsimony analysis of endemism (PAE). We constructed a matrix based on distribution data for Chinese Tetrigidae insects and an area cladogram using northeastern China area as an outgroup. Exhaustive searches were conducted under the maximum parsimony criterion. Cluster analysis divided eight biogeographic areas into four groups; group 1 was composed of northeast China, group 2 was composed of Mongolia-Xinjiang, group 3 was composed of central, eastern, and northern China, and group 4 was composed of southern and southwestern China and Qinghai-Xizang. The area cladogram suggested that northeastern China and Mongolia-Xinjiang formed earlier than others. This phenomenon is likely related to Pleistocene glacier movements. In general, Tetrigidae insect diversity was higher in southern China than northern China. We speculate that this pattern can be partially explained by the Pleistocene forest refuge theory and eco-environmental deterioration.
