Future global climate and land use changes will probably have strong impacts on tropical biodiversity hotspots and need to be addressed scientifically. Past environmental changes and their role in the development and dynamic of ecosystems can be reconstructed by palaeoecological methods, which help to understand ecosystem functioning. A relatively large number of palaeoecological data sets from the Podocarpus National Park (PNP) region, provided during previous phase, and a few additional data sets as well as modern vegetation/pollen rain studies will be used to reveal patterns of mountain vegetation and plant diversity dynamics. Their response to past climate, fire, land use changes will be investigated in detail. Results of in the southern Ecuadorian Andes and the Mata Atlantica biodiversity hotspot in South America will be compared and synthesised as a contribution for management and conservation concepts in biodiversity hotspots. Gaps regarding the reconstruction of vegetation and other environmental changes in the eastern PNP region will be filled. The visualisation and modelling of the data as well as studies on the upper forest line dynamics during the past will be extended.

未来的全球气候和土地利用变化可能会对热带生物多样性热点产生强烈影响，需要科学地解决。过去的环境变化及其在生态系统发展和动态中的作用可以通过古生态学方法重建，这有助于了解生态系统的功能。前一阶段提供的罗汉松国家公园（PNP）地区相对大量的古生态数据集以及一些额外的数据集以及现代植被/花粉雨研究将用于揭示山地植被和植物多样性的模式动力学。他们对过去气候、火灾、土地利用变化的反应将得到详细调查。将比较和综合厄瓜多尔安第斯山脉南部和南美洲马塔大西洋生物多样性热点地区的结果，作为对生物多样性热点地区管理和保护概念的贡献。东部 PNP 地区植被重建和其他环境变化方面的差距将得到填补。数据的可视化和建模以及过去对林线上游动态的研究将得到扩展。
