Tropical ecosystems are particularly valuable not only because they harbour high biodiversity, but also because they provide a number of ecosystem services, carbon storage being among the most important ones. Forests in the tropics have been under significant pressure due to timber harvest, land use change and fragmentation. Furthermore, there is a growing body of evidence suggesting that climate change is likely to have a significant impapact on tropical systems. The interaction between forest degradation and climate change threatens the sustainability of tropical ecosystems and good knowledge of the forest dynamics is needed to inform effective forest management and conservation efforts. Lianas are large woody vines that have been observed to raise in abundance in neotropical forests most likely due to human-mediated global change. They have the potential to contribute to forest degradation by inducing collateral damage during tree fall by pulling neighbouring trees down, smothering seedlings and biasing forest regeneration towards faster growing species, ultimately reducing the forest capacity to store carbon. Therefore, pantropical understanding of liana dynamics is of increasing importance.Lianas in Southeast Asia have been particularly understudied and this project aims to contribute to filing this knowledge gap. Analysis of liana cover will determine what are the best predictors of diversity and abundance and comparison between is rare vs. common and early vs. late-successional species will pinpoint the traits that make lianas successful. Unprecedented large scale sequencing of functional elements in non-model organisms will provide insights of liana evolution and employed strategies. Further components of the project will look into the impact of liana on carbon storage as well as effect of palm oil cultivation and forest fragmentation on liana cover

热带生态系统特别有价值，不仅因为它们拥有高度的生物多样性，还因为它们提供了许多生态系统服务，碳储存是最重要的服务之一。由于木材采伐、土地利用变化和破碎化，热带地区的森林承受着巨大的压力。此外，越来越多的证据表明，气候变化可能对热带系统产生重大影响。森林退化和气候变化之间的相互作用威胁着热带生态系统的可持续性，因此需要充分了解森林动态，以便为有效的森林管理和养护工作提供信息。藤本植物是大型木本藤本植物，在新热带森林中被观察到数量增加，这很可能是由于人类介导的全球变化。它们有可能导致森林退化，在树木倒下时造成附带损害，将邻近的树木拉倒，使幼苗窒息，使森林更新倾向于生长更快的物种，最终降低森林储存碳的能力。因此，对藤本植物动力学的泛热带理解变得越来越重要。对东南亚藤本植物的研究尤其不足，本项目旨在弥补这一知识缺口。藤本植物覆盖度的分析将决定什么是多样性和丰度的最佳预测因子，而将其罕见与常见、早期与晚期演替物种进行比较将确定使藤本植物成功的特征。在非模式生物中前所未有的大规模功能元件测序将提供藤本植物进化和使用策略的见解。该项目的进一步组成部分将研究藤本植物对碳储存的影响，以及棕榈油种植和森林破碎化对藤本植物覆盖的影响
