森林热带生态系统在受到干扰后重建所需的时间受到广泛关注。然而，迄今为止，还没有对热带生物群落进行比较研究，以确定森林再生长的速度，以及它们在空间和时间上的变化。在这里，我们提出了一个荟萃分析的古生态记录，使用化石花粉作为植被变化的代理在过去的20,000年。71项研究报告了四个热带地区共283起森林扰动和恢复事件。研究结果表明，中美洲和非洲的森林从过去的干扰中恢复的速度一般比南美洲和亚洲的森林快，与气候和人类影响后相比，遭受大规模罕见自然干扰的森林也是如此。结果还表明，随着时间的推移，在一个网站的干扰事件的频率增加，提高恢复率，表明一定程度的弹性暴露于经常性的过去干扰的森林。 在过去的干扰之后恢复森林有助于了解森林将如何应对未来的情景。在这里，作者分析了热带森林的古生态记录，发现中美洲和非洲的森林在干扰后比南美洲和亚洲的森林恢复得更快。
The time taken for forested tropical ecosystems to re-establish post-disturbance is of widespread interest. Yet to date there has been no comparative study across tropical biomes to determine rates of forest re-growth, and how they vary through space and time. Here we present results from a meta-analysis of palaeoecological records that use fossil pollen as a proxy for vegetation change over the past 20,000 years. A total of 283 forest disturbance and recovery events, reported in 71 studies, are identified across four tropical regions. Results indicate that forests in Central America and Africa generally recover faster from past disturbances than those in South America and Asia, as do forests exposed to natural large infrequent disturbances compared with post-climatic and human impacts. Results also demonstrate that increasing frequency of disturbance events at a site through time elevates recovery rates, indicating a degree of resilience in forests exposed to recurrent past disturbance. Forest recovery after past disturbances can help to understand how forests will respond to future scenarios. Here, the authors analyse palaeoecological records from tropical forests and find that Central American and African forests have recovered faster after disturbances than those in South America and Asia.
