Montane forests in the Andes and the South-eastern Brazilian Mountain Range host the highest plant biodiversity on Earth. Current rates of warming in the Andes are three times higher than elsewhere in S. America, and higher than average warming of 5-6oC is predicted by the end of this century. Hence, the (sub)tropical mountain ranges in Latin America form a high-priority area in which to study the response of tropical trees under future environmental change. Tropical forests also play a crucial role in the global carbon budget, accounting for more than half of terrestrial net primary production and storing around 40% of plant biomass. Uncertainty in the response of tropical forests to global warming is responsible for a large uncertainty in atmospheric CO2 concentrations under any given scenario of anthropogenic CO2 emissions. However, the current generation of Dynamic Global Vegetation and Earth System Models do not include a representation of montane forest functioning, which stems from a lack of empirical understanding, leading to a consideration of only lowland tropical forests in models. We intend to address this knowledge gap by initiating a Latin America-wide network of tropical montane forest sites to gather existing understanding in order to model the contribution of these forests to the regional and global carbon and water cycles, under current and future climate change. This will be achieved via a dedicated workshop at the Uni-Campinas, Brazil, hosted by PP-FAPESP Nagy, with the participation of empirical experts across the network together with DGVM and ESM modellers.

安第斯山脉和巴西东南部山脉的山地森林拥有地球上最高的植物生物多样性。安第斯山脉目前的升温速度是南美洲其他地区的三倍，预计到本世纪末将比平均升温5-6摄氏度更高。因此，拉丁美洲的(亚)热带山脉构成了研究热带树木在未来环境变化中的反应的高度优先区域。热带森林在全球碳收支中也发挥着至关重要的作用，占陆地净初级生产量的一半以上，储存了约40%的植物生物量。热带森林对全球变暖的反应的不确定性是造成在任何给定的人为二氧化碳排放情景下大气二氧化碳浓度存在很大不确定性的原因。然而，当前一代动态全球植被和地球系统模型没有包括山地森林功能的表示，这是由于缺乏经验认识，导致在模型中只考虑低地热带森林。我们打算通过发起一个拉丁美洲范围的热带山地森林地点网络，收集现有的认识，以模拟在当前和未来气候变化下，这些森林对区域和全球碳和水循环的贡献，从而解决这一认识差距。这将通过由PP-FAPESP Nagy主办的在巴西Uni-Campinas举办的专门讲习班实现，整个网络的经验专家将与DGVM和ESM模型师一起参加。
