The ecological role of intertidal microphytobenthos (MPB) is increasingly recognized in coastal production systems. MPB primary production (PP) measured in coastal wetlands of Korea, Cambodia, and Australia confirmed large variability at the global scale. Surprisingly, MPB biomass in mangrove forests almost doubled those measured in nearby bare tidal flats. However, MPB productivity (P) in vegetated habitats was significantly reduced (by ~50%) compared to that on bare tidal flats. Extensive measurements of MPB biomass, PP, and P across 12 Korean tidal flats revealed large spatiotemporal variations, suggesting complex sediment-MPB coupled dynamics. The key factors included sediment type, tide, bed elevation, irradiation, temperature, and vegetation. Winter MPB blooms and the elevated P seem to be unique characteristics of the Korean intertidal flats. The present study provides the baseline data of MPB PPs in mudflat, saltmarsh, and mangrove habitats in the highly productive zones of the Western Indo-Pacific Rim.

Grey mullets (family Mugilidae) are widespread across coastal, brackish, and freshwater habitats, and have supported fisheries for millennia. Despite their global distribution and commercial value, little is known about their movement ecology and its role in the co-existence of sympatric mullet species. Gaps in knowledge about migratory behaviour, seasonal occurrence, and movement scales have also impeded effective management, highlighting the need for further research.

Coastal ecosystems play a major role in marine carbon budgets, but substantial uncertainties remain in the sources and fluxes of coastal carbon dioxide (CO). Here, we assess when, where, and how submarine groundwater discharge (SGD) releases CO to shallow coastal ecosystems. Time-series observations of dissolved CO and radon (Rn, a natural groundwater tracer) across 40 coastal systems from 14 countries revealed large SGD-derived CO fluxes.

Artificially planted mangroves are widely used for tidal flat restoration, but their effectiveness in restoring these ecosystems remains unclear. Macrobenthos, as key indicators of tidal flat ecosystem health, can reflect changes in environmental conditions and quality resulting from the introduction of artificial mangroves. This study aimed to investigate the ecological restoration effects of artificially planted mangroves in northern China by surveying macrobenthic communities across four regions in June 2023.

Article Synopsis
- Tidal flats are critical for biodiversity along coastlines but are often confused with turbid waters in mapping efforts due to similar sediment characteristics.
- A new Tidal Flats-Water Difference Index (TWDI) was developed using time series Sentinel-2 data for accurate tidal flat mapping in China for 2020, achieving a 0.97 overall accuracy.
- The resulting Tidal Flats Map of China (TFMC) identified a total area of 9195.80 km of tidal flats and serves as a valuable tool for enhancing conservation and sustainable development in coastal wetland ecosystems.

Article Synopsis
- Tidal flats, located behind mangrove forests, are important coastal ecosystems impacted by both ocean and land activities, and this study examined microplastics (MPs) in these areas in southwest Puerto Rico.
- Researchers found an average of 148.64 MPs per kg in sediment samples, with most MPs being small (0.3-1 mm) and increased concentrations found farther from mangroves at three sites.
- Notably, polyethylene was the most common type of plastic identified, and while mangrove cover helped reduce MP accumulation, better waste management is also essential to protect these ecosystems from plastic pollution.
