Summary: Mangrove, seagrass, and coral habitats in tropical and subtropical regions are interconnected and have varying effects on CO2 dynamics and air-water fluxes. Different habitats contribute differently to atmospheric CO2, and biogeochemical processes along coastal areas play a key role in carbon cycling.

Summary: This study provides a scientific understanding and classification of nested mangrove-coral (CMC) habitats, and reports the discovery of a highly rich CMC habitat type in Panama. Based on literature review and field data, the researchers created a classification framework for CMC habitat categories and used GIS modeling to predict potential global distribution of CMC habitats.

Summary: Crab activities influence various ecological and biogeochemical processes in mangroves through bioturbation, leaf litter consumption, and fecal deposition. Factors such as sediment characteristics and seasonal variations play a significant role in burrow dynamics and maintenance. The study highlights the importance of understanding the spatial and seasonal variations in order to estimate the bioturbation effects on mangrove biogeochemical cycles.

Summary: This study evaluates the biophysical limitations to mangrove-seedling persistence by measuring the anchoring force of two mangrove species. The study found that the anchoring force of Rhizophora mangle seedlings was consistently higher than Avicennia germinans, but the rate of increase in anchoring force with growth was faster for Avicennia germinans. Increasing the density of surrounding vegetation had a positive effect on the anchoring force of both species.

Summary: Mangrove estuaries are economically valuable and biologically diverse coastal ecosystems. However, knowledge about emerging pollutants in mangrove estuaries is limited. This study investigated PFAS concentrations in a continuous river-mangrove estuary-bay system in China, revealing a declining trend of PFAS concentrations from the river to the bay. The primary sources of PFAS pollution were identified as wastewater treatment plant effluent, domestic and production wastewater discharge, aqueous film-forming foam emissions, and fluorochemistry industry wastewater. PFAS pollution in the mangrove creek was mainly influenced by domestic and production wastewater discharge, particularly during the rainy season.

Summary: As the transition zone between urban and rural areas, the metropolis fringe is characterized by the competition and permeation of various functions. Understanding land use functions (LUFs) and their relationships is crucial for sustainable development. This study established a conceptual framework and an improved evaluation method to quantify LUFs at the grid scale in the urban fringe. The findings showed pronounced spatiotemporal heterogeneity in LUFs trade-offs.

Summary: Plant-microbial fuel cells (PMFCs) are a sustainable technology that integrates plants, microorganisms, and electrode systems to convert sunlight into electricity. This study demonstrates that PMFCs installed on green roofs in a subtropical metropolis can effectively lower floor slab temperatures and potentially save energy for air conditioning. Different plant species in PMFC systems can affect electricity generation efficiency, with vegetation of PMFCs relieving soil heat flux and potentially leading to energy savings.

Summary: The mangrove ecosystem can efficiently alleviate nitrogen pollution, especially through nitrate reduction by Desulfobacterales. Nitrogen metabolism activities are significantly higher in the wet season compared to the dry season, with Desulfobacterales playing a key role in nitrogen cycling. Furthermore, environmental factors such as total phosphorus, available iron, and total organic carbon influence the distribution of nitrogen cycling genes.

Summary: Recent research indicates that the well-known South Atlantic coral reefs have ceased vertical growth and are dominated by non-coral calcifying organisms. In the southernmost subtropical Atlantic reef, calcareous algae and bryozoans play a key role in limiting erosion and maintaining the stability of the reef structure.

Summary: A 2-year study in subtropical Hong Kong waters revealed that external erosion caused by sea urchin grazing is the primary factor contributing to coral skeletal loss. Controlling the sea urchin population density is crucial to reducing coral erosion.

Summary: This study evaluates mangrove restoration efforts in the Leizhou Peninsula and Beibu Gulf in China, revealing that although the mangrove area has increased, the majority of patches exhibit low resilience. Therefore, relying solely on the increase in mangrove area as a measure of successful restoration is limited. Instead, expanding conservation boundaries to include remnant mangroves outside protected areas may be a more ecologically optimal solution.

Summary: This study investigates the methane emission fluxes from different species of trees in coastal mangrove wetlands. The results show that tree stems and pneumatophores are important conduits for methane emissions, with variations between different mangrove communities. The study also highlights the seasonal variations in methane fluxes, but no significant changes in the partitioning of ecosystem methane fluxes between the two seasons were observed.

Summary: Nitrogen (N) pollution and eutrophication can harm estuarine ecosystems, with understanding N sources and cycling crucial for management. In the Pearl River Estuary (PRE), a multiple-isotopic approach revealed contrasting N dynamics between the west and east, with NO3- largely influenced by mixing in the west and assimilation/nitrification in the east. River discharge and nitrification were major contributors to the NO3- pool, while NH4+ mainly originated from river discharge.

Summary: Polychaetes play a vital role in the structure and functioning of benthic communities in mangrove ecosystems. However, there is limited understanding of the diversity and functional structure of polychaete assemblages in different habitats in the Persian Gulf and Gulf of Oman. This study investigated the species and trait composition of polychaetes and environmental variables in vegeatated and mudflat habitats of three subtropical mangroves. The results showed significant differences in polychaete abundance, taxonomic diversity, species composition, and trait composition between habitats and regions.

Summary: Although many signals are known to regulate synapses, the mechanisms organizing initial synapse assembly are still unclear. This study introduces a new tool called SynTAMs, which enable localized perturbations of cAMP signaling, to investigate its role in synaptic development. The findings suggest that postsynaptic cAMP signaling is crucial for excitatory synapse formation, while not affecting neuronal maturation or inhibitory synapse formation. In addition, the study reveals the general importance of postsynaptic cAMP signaling in synapse replacement throughout life. These results provide insights into the spatial organization of postsynaptic specializations during synapse formation.
