项目摘要

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. Increasingly, secondary forests, plantations and other human-modified habitats will 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 biodiversity and the important biogeochemical cycles and ecosystem services associated with it in tropical landscapes 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 disturbance 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 the extent to which different elements of biodiversity (e.g. species of conservation concern) are associated with measures of ecosystem function (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 modelling.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 functioning and the distribution of species of conservation concern; and (4) Explore policy scenarios for optimising biodiversity and function protection.

热带森林支持世界上三分之二的陆地生物多样性。但是，已经降低了35％至50％的热带森林，森林砍伐的速度继续增加。越来越多的次要森林，人工林和其他人类修饰的栖息地将主导热带景观，导致人们担心这些景观的人类退化将提高温室气体的排放，并在地方，地区和全球范围内危害生态系统服务。受保护的森林地区将来不太可能大大增加，因此生物多样性的持久性以及与热带景观相关的重要生物地球化学周期和与之相关的生态系统服务在很大程度上取决于我们对待更广泛的热带热带景观的方式。人类改良的热带森林计划旨在“显着提高我们对热带森林中生物多样性与生物地球化学循环之间联系的理解”，通过“综合观察结果以及与森林修饰中梯度相关的建模”。为了实现这一目标，我们的财团将使用Sabah（马来西亚婆罗洲）安全景观中的干扰梯度进行调查来检测模式，并结合操纵性现场实验，以获得对生物多样性功能联系的机械理解。我们将评估不同生物多样性元素（例如，保护问题）与生态系统功能的度量（生物地球化学周期）有关的程度。然后，我们将从实验地点上升到景观尺度，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，以告知政策场景模型。因此，（1）（1）表征土壤微生物功能和测量相关的生物地球化学通量；（2）实验测试地上生物多样性与土壤功能之间的联系；（3）构建并添加到现有的鸟类和哺乳动物的数据集中，并探索功能与保护物种的分布之间的相关性；（4）探讨用于优化生物多样性和功能保护的政策方案。
