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一个主要特征，影响着世界上近一半的人口。季风对该地区的动植物和生态系统也有深远的影响。此外，中国的大部分地区也以其异常高的生物多样性而闻名。最后我们知道，这段时间间隔也见证了现代植被模式的诞生。那么这些方面是如何联系在一起的呢？为什么中国部分地区的生物多样性如此之高？这些生态系统是什么时候形成的？我们的项目旨在汇集一批世界领先的古生态学、地质学和气候模型研究人员，以确定古近纪和新近纪早期生态变化的本质，并建立变化的潜在机制和阈值。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数量，并在几个关键地点确定变化是平稳的还是相对突然的，后者表明系统可能的阈值行为。我们还将利用这些数据重建对这些遗址的气候和古海拔的估计。这些信息可以用来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。研究结果将使人们对地球上生命的进化有更全面的了解，也将使人们能够对用于未来气候变化预测的模型进行独特的评估。
