Mangroves have long been associated with human populations, as coastal communities rely on the various ecosystem services that mangroves provide. However, human degradation and destruction of mangrove forests is common, despite and because of our reliance on them as valuable ecosystems. Mangrove research and management must elucidate and reconcile these conflicts to maintain mangrove forests and the services that humans depend on. To better understand the complex dynamics, interactions and relationships that exist between mangroves and coastal communities, the 5^th Mangrove Macrobenthos and Management (MMM5) conference was held in Singapore in July 2019, with the theme “Mangroves and People: Impacts and Interactions”. This theme was chosen because Southeast Asia is the epicentre of ongoing mangrove loss, and a large number of coastal communities in the region rely on the ecosystem services that mangroves provide. The 32 papers published in this Special Issue represent the breadth of mangrove research presented at MMM5, including topics in faunal biology, ecosystem ecology, genetics, physical geography, biogeochemistry, remote sensing and the social sciences. The articles are characterized under the following topics: 1) mangrove ecosystem functioning; 2) range expansion of mangroves; 3) ecosystem services of mangroves; 4) anthropogenic and natural threats to mangroves; and 5) the management and social-ecology of mangroves. This Special Issue highlights the current state of the art of mangrove research and application, and describes a number of emerging new ideas and research opportunities that will continue to advance mangrove ecosystem science into the future.

由于沿海社区依赖于红树林提供的各种生态系统服务，所以红树林一直与人口息息相关。然而，尽管并且由于我们依赖于它们作为宝贵的生态系统，人类对红树林的退化和破坏还是很普遍的。红树林的研究和管理必须阐明和调解这些冲突，以维护红树林和人类赖以生存的服务。为了更好地理解红树林与沿海社区之间存在的复杂动力，相互作用和关系，2019年7月在新加坡举行了^第五届红树林宏观底栖动物与管理会议（MMM5），主题为``红树林与人：影响与相互作用''。之所以选择这个主题，是因为东南亚是红树林持续流失的中心，并且该地区的许多沿海社区都依赖红树林提供的生态系统服务。本期特刊中发表的32篇论文代表了在MMM5上发表的关于红树林研究的广度，包括动物生物学，生态系统生态学，遗传学，自然地理学，生物地球化学，遥感和社会科学等主题。这些文章的主题如下：1）红树林生态系统功能；2）扩大红树林的范围；3）红树林的生态系统服务；4）对红树林的人为和自然威胁；5）红树林的管理和社会生态。本期专刊重点介绍了红树林研究和应用的最新状况，
