To investigate the differences in soil hydrolytic enzyme activity and stoichiometry among different mangrove communities, as well driving factors behind these variations, we will explore their implications for nutrient limitations of microbes availability nutrients. This study focus on Rhizophora stylosa communities (RS), Aegiceras corniculatum (AC), RS-AC mixed (MF) within Hainan Xinying Bay conservation area, using adjacent bare flats (BF) a control group. We analyse physicochemical properties at depths 0–20 cm 20–40 across to uncover synergistic changes between variables. The results indicate following. (1) Except acid phosphatase (ACP), activities stoichiometric ratios differ significantly. In layer 0~20 cm, β-glucosidase (BG) is markedly diminished MF community relative other communities. Conversely, β-1,4-N-acetylglucosaminidase (NAG) leucine aminopeptidase (LAP) are most elevated MF. 20~40 layer, cellulase (CBH) was found be highest community, while BG NAG were significantly lower than those Overall, five enzymes decreased with increasing depth.

Mangrove forests are intertidal ecosystems that harbor diverse microbial communities essential for biogeochemical cycles and energy flow. This study investigated the seasonal spatial patterns of bacterial in artificially introduced mangrove sediments Ao River estuary using 16S rRNA gene amplicon high-throughput sequencing. Alpha diversity analyses indicated community was similar to those natural-formed mangroves, with Shannon index ranging from 5.16 6.54, which significantly higher winter compared other seasons. The dominant phyla included Proteobacteria (43.65%), Actinobacteria (11.55%), Desulfobacterota (11.16%), Bacteroidetes (5.52%), while beta analysis revealed substantial differences structure across different seasons regions. For instance, relative abundance Woeseiaceae Bacteroidota during summer than observed And Bacillaceae autumn increased by one order magnitude spring summer. Woeseiaceae, Desulfobulbaceae, Thermoanaerobaculaceae, Sva1033 (family Desulfobacterota) exhibited unvegetated area, whereas S085 Chloroflexi) demonstrated greater area. Seasonal variations primarily attributed changes environmental factors, including temperature salinity. Regional associated stressors, such as wave action, fluctuations salinity, organic matter content, further complicated changes. is significant understanding dynamics estuarine wetlands, it contributes assessment wetland restoration efforts Zhejiang Province, providing important guidance development strategies maintain health future.

Abstract Mangroves are coastal environments that provide resources for adjacent ecosystems due to their high productivity, organic matter decomposition, and carbon cycling by microbial communities in sediments. Since the industrial revolution, increase of Greenhouse Gases (GHG) released fossil fuel burning led many environmental abnormalities such as an average temperature ocean acidification. Based on hypothesis climate change modifies diversity associated with decaying mangrove sediments, this study aimed evaluate under simulated conditions during litter decomposition process emission GHG. Thus, microcosms containing from three main plant species found mangroves throughout State São Paulo, Brazil ( Rhizophora mangle , Laguncularia racemosa Avicennia schaueriana ) were incubated simulating changes (increase pH). The decay rate was higher first seven days incubation, but differences between treatments minor. GHG fluxes ten samples increased temperature. variation time resulted substantial impacts α-diversity community composition, initially a greater abundance Gammaproteobacteria all despite variations. PCoA analysis reveals chronological sequence β-diversity, indicating Deltaproteobacteria at end process. varied function source elevated temperature, concurrent rise population. these results indicate expected scenario century, emissions will be potentially higher, leading harmful feedback loop production. This can happen independently impact bacterial structure changes.
