Changes in organismic diversification rates with regard to the uplift of the Qinghai-Tibetan Plateau and associated climate and vegetation changes

青藏高原隆升及相关气候和植被变化导致的生物多样性变化

基本信息

项目摘要

We aim at comparing temporal shifts in diversification rates across various organismic groups (plants, birds, oomycetes and stream insects) with regard to major geological, climatic and palaeo-vegetation changes in the Qinghai-Tibetan Plateau (QTP) region, one of the earth's most significant topographic features. By focusing on the evolution of organisms from the Palaeogene up to the Pleistocene, we want to address the following questions: (1) Do changes in diversification rates of various taxonomic groups temporally coincide with major geological/tectonic or climatic events in the QTP region? (2) Are diversification rates higher for taxonomic groups occurring in the QTP region than in other high elevation areas of the world? Is the QTP biodiversity hotspot a result of increased diversification rates of its biotas? (3) Did major changes in palaeo-vegetation in the QTP region influence diversification rates of some, but not all of the study groups (e.g. birds)?
我们的目的是比较时间变化的多样性率在不同的有机类群(植物,鸟类,卵菌和流昆虫)的主要地质,气候和古植被变化在青藏高原(QTP)地区,地球上最重要的地形特征之一。通过对古近纪至更新世生物演化的研究,我们希望解决以下问题:(1)QTP地区不同分类群的多样性变化是否与主要的地质/构造或气候事件在时间上一致?(2)QTP地区分类群的多样化率是否高于世界其他高海拔地区?QTP生物多样性热点是生物多样性多样化率增加的结果吗?(3)QTP地区古植被的重大变化是否影响了某些而非所有研究群体(如鸟类)的多样化率?
