Tropical forests support over two-thirds of the world's terrestrial biodiversity. However, between 35% and 50% of tropical forests have already been degraded, and the rate of deforestation continues to increase. Secondary forests, plantations and other human-modified habitats now dominate tropical landscapes, leading to concerns that human degradation of these landscapes will elevate greenhouse gas emissions and jeopardise ecosystem services at local, regional and global scales. The area of protected forests is unlikely to increase greatly in the future, so the persistence of tropical biodiversity and the important biogeochemical cycles and ecosystem services associated with it will depend to a large extent on the way we treat the wider tropical landscape. The Human Modified Tropical Forests programme seeks to 'significantly improve our understanding of the links between biodiversity and biogeochemical cycles in tropical forests' through 'integrated observations and modelling linked to gradients in forest modification'. To contribute towards this goal our consortium will use surveys along a modification gradient within the SAFE landscape in Sabah (Malaysian Borneo) to detect patterns, combined with manipulative field experiments to gain a mechanistic understanding of biodiversity-function linkages. We will assess links between above- and belowground components of tropical biodiversity and investigate the extent to which different elements of biodiversity (e.g. species of conservation concern) are associated with measures of ecosystem function (decomposition processes and biogeochemical cycles). We will then upscale from the experimental sites to the landscape-scale to generate spatial layers of ecosystem function, biodiversity, and greenhouse gas fluxes to inform policy scenario modeling. Our work will thus (1) characterise soil microbial function and measuring associated biogeochemical fluxes; (2) Experimentally test the links between aboveground biodiversity and soil function; (3) Build and add to existing datasets for bird and mammals, and explore correlations between ecosystem functioning and the distribution of species of conservation concern; and (4) Explore policy scenarios for optimising biodiversity and function protection.

热带森林支持着世界上三分之二以上的陆地生物多样性。然而，35%到50%的热带森林已经退化，森林砍伐率继续上升。次生林、种植园和其他人为改变的栖息地现在主导着热带景观，导致人们担心这些景观的人类退化将增加温室气体排放，并危及地方、区域和全球规模的生态系统服务。受保护森林的面积在未来不太可能大幅增加，因此热带生物多样性的持久性以及与之相关的重要生物地球化学循环和生态系统服务在很大程度上将取决于我们对待更广泛的热带景观的方式。人类改良热带森林方案试图通过“与森林改良中的梯度有关的综合观测和建模”，“显著提高我们对热带森林生物多样性和生物地球化学循环之间的联系的了解”。为了实现这一目标，我们的联合体将使用沙巴州(马来西亚婆罗洲)安全地貌内沿修改坡度的调查，以发现模式，并结合操纵性实地实验，从机械上了解生物多样性与功能之间的联系。我们将评估热带生物多样性地上和地下组成部分之间的联系，并调查不同的生物多样性要素(例如，受保护的物种)与生态系统功能(分解过程和生物地球化学循环)的衡量标准之间的关联程度。然后，我们将从试验点升级到景观规模，以生成生态系统功能、生物多样性和温室气体通量的空间层，为政策情景建模提供信息。因此，我们的工作将(1)表征土壤微生物功能并测量相关的生物地球化学通量；(2)通过实验测试地上生物多样性和土壤功能之间的联系；(3)建立和增加现有的鸟类和哺乳动物数据集，并探索生态系统功能与受保护物种分布之间的关系；(4)探索优化生物多样性和功能保护的政策方案。
