藤本植物在新热带森林中的密度、生物量和生产力都在增加，迄今为止有12项研究记录了这种模式。已经提出了几种假设来解释新热带森林中藤本植物丰度增加的现象，包括森林干扰和周转的增加（例如，土地利用和破碎化的变化）、季节性干旱强度和年降雨量减少、大气CO2浓度升高和养分沉积。本章综合了现有的支持证据，表明在过去的三十年里，新热带森林中的藤本植物的丰度和生物量都有所增加。它回顾了热带森林中藤本植物丰度增加的最可能驱动因素的假设，并为每个假设提供了证据（或缺乏证据）。它的结论与未来的研究模式，机制，并在新热带森林藤本植物增加的潜在大规模的影响的建议。
Lianas are increasing in density, biomass, and productivity in neotropical forests and there are 12 studies to date documenting this pattern. Several hypotheses have been proposed to explain the phenomenon of increasing liana abundance in neotropical forests, including increases in forest disturbance and turnover (e.g., changes in land use and fragmentation), intensity of seasonal drought and lower annual rainfall, elevated atmospheric CO2, and nutrient deposition. This chapter synthesizes the available supporting evidence that lianas have increased in abundance and biomass over the past three decades in neotropical forests. It reviews the hypotheses for the most likely drivers of increasing liana abundance in tropical forests and provides the evidence (or lack thereof) for each of them. It concludes with recommendations for future studies of the patterns, mechanisms, and potential large‐scale ramifications of liana increases in neotropical forests.
