SUMMARY:

Mangroves and saltmarshes are two of the most relevant coastal habitats for humans. Those coastal ecosystems offer several services like coastal protection, climate mitigation, and serve as nursery habitats for many artisanal and commercial exploited fish. Mangroves and saltmarshes occur on different latitudinal ranges with little overlap, thus many studies focus exclusively on one of them and few on the ecological interactions between them and how they relate to climate change. Here, we review the current scientific knowledge on saltmarsh-mangrove ecological interactions. A search was performed on both Science Direct and Web of Science platforms. We screened 1,319 articles from 1945 to 2020 and selected 25 that assessed saltmarsh-mangrove ecological interactions. Most studies were on mangrove encroachment in the Gulf of Mexico due to climate change. Several articles showed higher retention, establishment, and survival of mangrove propagules inside saltmarshes, i.e. facilitation, than on bare flats. They also showed a higher effect of saltmarsh grass when compared to the succulent marsh species. Nevertheless, articles assessing seedlings, saplings, or trees found mostly competition between mangrove and saltmarsh, with a negative effect on mangrove growth. By and large, in the absence of extremely low temperatures, mangroves are likely to be facilitated and outcompete saltmarshes. Our review showed that plant interactions play an important role in the mangrove-saltmarsh transition, like climate-change-induced mangrove encroachment into saltmarshes. Additionally, propagule facilitation by saltmarsh should be considered in mangrove restoration projects. Future studies should focus on mangrove-dominated regions (e.g., tropical systems), where changes in saltmarsh and mangrove interactions due to sea-level rise and coastal changes are virtually unknown.
