The Asian monsoon system is a major feature of the Earths climate and impacts on almost half of the population of the world. The monsoon also has a profound effect on the regions flora, fauna and ecosystems. Moreover large parts of China are also noted for their exceptionally high biodiversity. We also know that the monsoon system has changed over geological time and this is intimately linked to the growth of Tibet and the Himalayas which occurred during the Paleogene (66 to 23 million years ago) and early Neogene (23 million years ago to 3 million years ago). And finally we know that this time interval also witnessed the birth of this modern vegetation patterns. So how are all of these aspects linked together. Why is biodiversity so high in parts of China? When did these ecosystems develop? And how is this all connected to Tibetan uplift and the evolution of the monsoon?Our project aims to bring together a unique group of world leading researchers in palaecology, geology and climate modelling to identify the nature of ecological change during the Paleogene and early Neogene and establish the underlying mechanism of changes and thresholds.We will do this with a series of three field trips to span the latitudinal and elevation gradients within China, from Tibet, Yunnan and S. China. These field trips will enable us to collect new information on the changes in ecosystem and biodiversity. We will be able to assess the amount of change, and in a few key sites identify whether the changes have been smooth or relatively abrupt, the latter indicating possible threshold behaviours of the system. We will also use this data to reconstruct estimates of the climate and palaeoelevation of the sites. This information can then be used to help develop and test climate, ecosystem, and biodiversity models. These models will allow us to identify the key mechanisms that have driven change in this region over geological time, and the interactions between the ecosystem and climate change.The outcomes will be a fuller understanding of the evolution of life on the planet, and will also enable a unique evaluation of the models used for future climate change projections.

亚洲季风系统是地球气候的主要特征，对世界几乎一半的人口影响。季风也对区域动植物，动物群和生态系统产生了深远的影响。此外，中国的大部分地区也因其异常高的生物多样性而闻名。我们还知道，季风体系在地质时期发生了变化，这与西藏和喜马拉雅山脉的增长密切相关，该增长发生在古近纪（66至2300万年前）和新纪（2300万年前）（300万年前）。最后，我们知道这个时间间隔也见证了这种现代植被模式的诞生。因此，所有这些方面如何联系在一起。为什么中国部分生物多样性如此之高？这些生态系统何时发展？这一切如何与藏族的隆起和季风的演变有关？我们的项目旨在将一群独特的世界领先的研究人员汇集在一起​​，领域领域的领先研究人员，地质学，地质和气候模型，以确定古次和新吻合元期间的生态变化的性质，并建立了一系列变化和Threshold的基本机制，我们将在一系列的范围内与范围升级。云南和中国。这些实地考察将使我们能够收集有关生态系统和生物多样性变化的新信息。我们将能够评估变化的量，并且在一些关键站点中，我们将确定更改是平稳还是相对突然的，后者表明系统可能的阈值行为。我们还将使用这些数据来重建对站点气候和古征的估计。然后，这些信息可用于帮助开发和测试气候，生态系统和生物多样性模型。这些模型将使我们能够确定在地质时期驱动该地区变化的关键机制，以及生态系统与气候变化之间的相互作用。结果将是对地球上生命进化的更深刻理解，还将对用于未来气候变化预测的模型进行独特的评估。
