Salt marsh and mangrove have been recognized as being among the most valuable ecosystem types globally in terms of their supply of ecosystem services and support for human livelihoods. These coastal ecosystems are also susceptible to the impacts of climate change and rising sea levels, with evidence of global shifts in the distribution of mangroves, including encroachment into salt marshes. The encroachment of woody mangrove shrubs and trees into herbaceous salt marshes may represent a substantial change in ecosystem structure, although resulting impacts on ecosystem functions and service provisions are largely unknown. In this review, we assess changes in ecosystem services associated with mangrove encroachment. While there is quantitative evidence to suggest that mangrove encroachment may enhance carbon storage and the capacity of a wetland to increase surface elevation in response to sea-level rise, for most services there has been no direct assessment of encroachment impact. On the basis of current understanding of ecosystem structure and function, we theorize that mangrove encroachment may increase nutrient storage and improve storm protection, but cause declines in habitat availability for fauna requiring open vegetation structure (such as migratory birds and foraging bats) as well as the recreational and cultural activities associated with this fauna (e.g., birdwatching and/or hunting). Changes to provisional services such as fisheries productivity and cultural services are likely to be site specific and dependent on the species involved. We discuss the need for explicit experimental testing of the effects of encroachment on ecosystem services in order to address key knowledge gaps, and present an overview of the options available to coastal resource managers during a time of environmental change.

“…Our results showed that the nematode assemblage at the mangrove habitat (stations 4, 6–8) was different from that at the mangrove habitat with reed (stations 9–12). Habitat type is considered important in structuring benthic metacommunities at both local and global scales (Fu et al, 2017; Pinto et al, 2013; Song et al, 2017). The most dominant nematode genera at the mangrove habitat (groups A, stations 4, 6–8) and at mangroves with reed (group B, stations 9–12) were Parodontophora and Anoplostoma , respectively.…”

“…It is known that meiofaunal communities provide a valuable tool for environmental assessments because of their fast response to environmental changes, and that they are more tolerant to oxygen depletion than benthic macrofauna (Alves, Caetano, Costa, Costa, & Marques, 2015; Austen & Wibdom, 1991; Della Patrona et al, 2016; Josefson & Widbom, 1988; Semprucci, Sbrocca, Baldelli, Tramontana, & Balsamo, 2017). Meiofauna are well studied in estuaries (Ansari & Parulekar, 1993; Bownes & Perissinotto, 2012; Capdeville et al, 2018; Costa, Valenca, & dos Santos, 2016; Fu, Cai, Cao, & Chen, 2017; Smol, Willems, Govaere, & Sandae, 1994; Soetaert, Vincx, Wittoeck, Tulkens, & Gansbeke, 1994; Yin, Tan, Yuan, Hu, & Liu, 2017). But there are only a few studies about meiofauna communities from upstream to the mouth of a river estuary, where those communities are exposed to steep environmental gradients (Quang et al, 2018; Semprucci et al, 2015).…”

This study aims to determine whether the benthic meiofaunal assemblages on the intertidal zone of Danshuei River estuary (DRE) in Taiwan vary from the estuary to the upper stream, and in response to different habitats. A total of six major taxa (Nematoda, Copepoda, Ostracoda, Polychaeta, Oligochaeta and Gastrotricha) of meiofauna and 44 nematode genera were recorded at 12 sampling stations in DRE in October, 2013. Meiofauna densities ranged between 4.67 ± 2.08 and 294.00 ± 180.40 ind./10 cm2, the average was 162.31 ± 84.36 ind./10 cm2. Nematodes were the dominant group (relative abundance, RA: 89.27%) in the meiofaunal community at all stations, with its assemblage in DRE dominated by nonselective deposit feeders (55.14%). There were striking differences in nematode assemblages between mangroves and mangroves with reed habitats. Pearson's correlation analysis showed that the dominances of the genera Anoplostoma, Metacylicolaimus and Deontostoma were significantly negative while Terschellingia correlated positively with salinity. These genera showed either decreasing or increasing trends at stations from the estuary to the upper stream. The dominances of the genera Megadesmolaimus and Theristus were significantly positively correlated with the proportion of sand and negatively correlated with the proportion of silt and clay. Our results indicate that salinity and sediment type influenced nematode assemblages in the DRE.
