Summary: The study compared ecosystem organic carbon stocks and soil organic carbon sources between two 12-year-old mangrove sites with different species. Results showed that mangrove vegetation sequestered organic carbon more rapidly than soil pool, with different species impacting carbon sequestration performance. This suggests that attention should be paid to the carbon sequestration features of rehabilitated mangrove forests in future programs.

Summary: This study investigated the impact of nitrogen deposition on the sequestration potential of PhytOC in coastal wetland soils through indoor tidal simulation experiments. The results showed that the introduction of Kandelia obovata significantly increased the occluded carbon content of soil phytoliths and the PhytOC content in the soil. However, exogenous nitrogen input reduced the PhytOC content in the soil, with a greater impact on the non-plant group. Soil microbial biomass carbon and microbial biomass nitrogen were identified as the main factors influencing changes in PhytOC.

Summary: In this study, the toxic effects of three typical microplastics (polyethylene, polypropylene, and polyvinylchloride) in mangroves were investigated using the plant species Kandelia obovata. The microplastics were mixed into the soil at a concentration of 5% (w/w) and the cultivation was carried out in a mangrove tide-tank system for 12 months. The results showed that the microplastics significantly inhibited root growth, leaf ionome, chlorophyll concentration, and photosynthetic efficiency of the Kandelia obovata plants. The microplastics also affected soil properties, reducing bulk density but increasing porosity.

Summary: Soil carbon burial is crucial for mangroves to function as carbon sinks, however, the contribution of allochthonous or autochthonous inputs to the soil carbon pool remains uncertain. This study constructed carbon budgets to estimate mangrove-derived carbon burial rates for two species (K. obovata and A. marina) with different root structures. The results showed positive correlations between carbon burial rates and litterfall production, indicating that 14.8% and 10.9% of litterfall production rate can be used to estimate carbon burial rates for K. obovata and A. marina, respectively. Factors such as wind speed and precipitation were found to affect carbon burial in both species.

Summary: Mangroves are important in carbon sequestration but can also be sources of greenhouse gas emissions, especially methane. This study in Taiwan found that mangrove soils were significant sources of methane emissions, with Avicennia marina mangroves emitting much more than Kandelia obovata mangroves. Soil salinity and pH were key factors affecting methane emissions in K. obovata mangroves, while pneumatophore density was a major factor in A. marina mangroves. The root structure was found to affect greenhouse gas emissions from mangroves.

Summary: This study investigated the toxic effects of decabromodiphenyl ether (BDE-209) on the antioxidative and non-antioxidative responses of the mangrove species Kandelia obovata. Results showed that BDE-209 did not negatively affect the growth of K. obovata seedlings, but stimulated the activity of certain enzymes only in weeks 1 and 4. The production of reactive oxygen species was induced only at high concentrations of BDE-209, and BDE-209 was taken up, translocated, and accumulated by the plants. These findings highlight the ability of mangrove plants to accumulate PBDEs and the difficulty in removing BDE-209 from mangrove systems.

Summary: In this study, a virus-induced gene silencing system (VIGS) was established in K. obovata, using tobacco rattle virus (TRV) as the vector and the phytoene desaturase gene KoPDS as the target gene. The system was successfully used to verify the role of a Chlorophyll a/b binding protein (Cab) gene KoCAB in leaf carbon sequestration of K. obovata. The TRV-mediated VIGS system established in this study is the first genetic analysis tool for mangroves, which may greatly advance functional genomics studies in mangrove plants.

Summary: This study quantified the soil organic carbon (SOC) and labile organic carbon (LOC) in different depths of soil at four sites in Yingluo Bay, China. The results showed that the natural expansion of mangroves has a positive impact on SOC and LOC, with the 80-year old mangrove site having the highest concentrations of SOC, LOC, and CMI. Therefore, promoting the natural expansion of mangroves can maximize the storage potential of soil organic carbon.

Summary: By studying the impact of new conservation management (NCM) and conventional tillage (CT) on soil organic carbon (SOC) in summer maize monocultures in Northeast China, it was found that NCM had significantly higher microbial biomass carbon (MBC) and light fraction organic carbon (LFOC) content than CT in the upper 0-10 cm layer. Additionally, NCM reduced organic carbon storage in microaggregates. Therefore, NCM is an effective management choice for enhancing soil carbon sequestration in maize field systems in Northeast China.

Summary: This study analyzed the effects of site and climate on the self-thinning line in Scots pine forests in Europe. The results showed that species tolerance, temperature, and precipitation influenced the slope of the self-thinning line. In terms of the intercept, latitude and radiation had compensating effects. Time did not show significant trends in the self-thinning line. The study highlights the need to adapt management strategies and models based on self-thinning to different latitudes. Climate change has not yet significantly impacted the self-thinning trajectory, but a continuous rise in temperature and high precipitation may accelerate the self-thinning process and result in increased biomass accumulation.

Summary: Secondary forests play a crucial role in ecosystem dynamics and biodiversity recovery. This study investigated the mechanisms underlying secondary succession in a restored secondary forest and found that deciduous tree species transition from diversity accumulators to repellents as they progress through different life history stages, while evergreen tree species can act as accumulators or remain neutral. The study also revealed the effects of density dependence on the mortality and regeneration of different tree species, and highlighted the importance of early-arriving tree species in facilitating the establishment and diversity of late-arriving counterparts.

Summary: Fagus sylvatica L. is a competitive tree in European temperate deciduous forests, but often sporadic or absent in present-day stands where Quercus spp. are dominant. Through soil charcoal analysis in the Lorraine Plateau in France, the presence of Fagus and Quercus in mature Quercus stands was confirmed. Radiocarbon dating results indicated that historical forest management caused the replacement of Fagus by Quercus, starting from the Bronze Age.

Summary: Regeneration failures in the closed-crown boreal forest, resulting in the creation of open lichen woodlands, can be restored through clear-cutting, scarification, and natural seeding. Clear-cutting combined with scarification promotes seedling establishment, and scarification creates suitable microsites for germination. Seedling growth in lichen woodlands is higher when logging and scarification are combined, but lower compared to feather moss stands. Afforestation through natural seeding following scarification could be a cost-effective option for restoring lichen woodlands.
