Catchment scale hydro-biogeochemical fluxes and aquatic diversity under global change

拟议的研究有助于实现以下总体目标：（一）更好地了解热带山地森林系统在自然和改变条件下复杂的水文地球化学和生物相互作用;（二）将这一知识纳入一个综合建模系统，该系统将在长期和空间密集的数据集上进行测试;以及（iii）预测气候变化情景对水文地球化学和生物过程可能产生的影响，同时考虑每个过程预测的不确定性范围。该项目的一个主要交付成果将是扩大的CMF建模工具，能够模拟土地使用和气候变化对水文地球化学过程和生物相互作用的综合影响。该项目遵循实验者和建模者之间合作研究的一般理念，从而促进了最先进的系统理解到仿真工具的实施。因此，D4中开发的综合模型框架将能够评估全球变化对厄瓜多尔热带山地雨林生态系统的可能影响。

The proposed research contributes to the following overarching goals: (i) better understanding of the complex hydro-biogeochemical and biological interactions in tropical montane forest systems under natural and altered conditions; (ii) the integration of this knowledge in an integrated modeling system that will be tested to long-term and spatially dense datasets; and (iii) prognosis of the likely impact of climate change scenarios on the hydro-biogeochemical and biological processes considering for each process the uncertainty range on the prediction. A main deliverable of the project will be the expanded CMF modeling tool enabling the simulation of the combined impact of land use and climate change on hydro-biogeochemical processes and biological interaction. The project follows the general philosophy of cooperative researchers between experimentalists and modelers, thereby facilitating the implementation of state-of-the-art system understanding into simulation tools. The integrated modelframework developed in D4 will therefore allow to assess the likely impacts of global change on tropical montane rainforest ecosystems of Ecuador.
