Abstract Large‐scale anthropogenic mangroves have been constructed in coastal regions worldwide but our understanding of their ecological effects is limited. In particular, the question whether and how influence biodiversity patterns remains elusive. Here, we investigated large‐scale on mangrove macrobenthos. Specifically, measure seek to explain differences species richness, abundance, assemblage composition distance‐decay effect before after construction mangroves. We surveyed assemblages gastropod, bivalve crab over a wide latitudinal extent (24–28°N) subtropical China. For each, calculated relationship After mangroves, found richness gastropods, bivalves crabs increased by 23.81%, 100% 20%, respectively. The gastropods decreased 25% 91.43%, while that remained virtually unchanged, which mediated dispersal rate With plantation, compositional similarity 28.57% 38.46%, suggesting monospecific planting exacerbate biotic homogenization. Altogether, these results indicate habitats increase diversity macrobenthos change taxonomic compositions reducing increasing Synthesis applications . emphasize afforestation wetlands can drive major changes benthonic communities. Monitoring assessing for presence functional faunas will be important determining future restoration maintaining economic aquaculture. Quantifying those terms regional contribute management based upon macroevidence rather than one‐sided local perspective.

Comparison of the coexistence pattern of mangrove macrobenthos between natural and artificial reforestation

Abstract The abandoned pond‐to‐mangrove restoration project provides greater advantages than tidal flats afforestation in restoring mangrove ecosystem services and will be the primary method for future. existing methods include artificial through ‘dike‐breaking, filling with imported soil tree planting’ natural ‘dike‐breaking succession’. However, little is known about which strategy (natural or restoration) more benefits to biodiversity of macrobethos. Given a prevailing view suggested that should preferred approach accelerating recovery vegetation structure tropical regions, we hypothesised higher macrobenthic complex community restoration. To test this hypothesis, ecological processes were monitored typical area Dongzhaigang Bay, China, where used concurrently. Differences biodiversity, compared using diversity indices, network analysis null models. Similar species composition niche overlap width among macrobenthos observed at sites. biotic heterogeneity interaction sites Macrobenthos assembly was both determined by deterministic processes, environmental filtering dominating, explained 52% 54% variations structures respectively. Although our findings did not validate research could support as projects, because it nature‐based solution

Drivers of the spatiotemporal patterns of the mangrove crab metacommunity in a tropical bay

Abstract Revealing community patterns and driving forces is essential in ecology a prerequisite for effective management conservation efforts. However, the mangrove ecosystem its important fauna group such as crabs, still lack multi‐processes research under metacommunity framework, resulting evidence theorical application gaps. To fill these gaps, we selected China's most representative bay reserve tropical zone stable experimental system conducted seasonal investigation (July 2020, October January 2021, April 2021) of crabs. We performed multi‐approach analysis using both pattern‐based mechanistic method to distinguish processes crab metacommunity. Our results showed that exhibits Clementsian pattern bay‐wide but influenced by local environmental heterogeneity spatial processes, thus representing combined paradigm species sorting mass effect. Moreover, long‐distance constraints are more pronounced compared factors. This reflected greater importance broad‐scale Moran's Eigenvector Maps, distance‐decay similarity, difference beta diversity dominated turnover component. changes throughout year, mainly due dominant functional groups caused stress water salinity temperature induced air precipitation. provides multi‐dimension data relevant analysis, offering clear understanding related mangroves, verifies applicability some general laws system. Future studies can address diverse spatiotemporal scales, gaining clearer serve ecosystems economically fishery species.
