Summary: This study assessed the spatiotemporal variation in marsh NPP (Net Primary Productivity) in the western Songnen Plain and found that climate change has an impact on it. The results showed that the NPP of marshes in the western Songnen Plain significantly increased from 2000 to 2020, with increased precipitation enhancing marsh vegetation NPP while increased mean summer temperature reducing it. Additionally, the study discovered the asymmetric effects of summer minimum and maximum temperature on marsh vegetation NPP for the first time.

Summary: Soil erosion has caused landscape problems in many parts of the world, especially in cold regions where permafrost conditions have changed due to climate warming. The Tibetan Plateau, strongly affected by global warming and human activities, has been a case of such erosion. Monitoring technologies, such as remote sensing and field surveys, have limitations in exploring soil erosion rates in this region due to resolution and disturbance factors.

Summary: Sediment cores from Lake Khanka (Xingkaihu) and Amur Bay were analyzed for Cs-137 and Pb-210 concentrations, mineralogical and elemental composition. The results showed that the investigated area is not contaminated, with maximum Cs-137 activity of 10 Bq/kg and inventory of 0.16 Bq/m(2). The sedimentation rate was estimated to be 1.6 mm/year in the eastern part of Lake Khanka and 0.43-0.5 mm/year in Amur Bay.

Summary: Modeling severe accident management guidelines (SAMG) into Level 2 probabilistic safety assessment (PSA) is crucial for realistically quantifying the safety of nuclear power plants (NPPs) and the effectiveness of SAMG. The inclusion of SAMG in the Level 2 PSA model led to a significant increase in the conditional containment intact probability and a considerable decrease in NPP risk, as demonstrated in the application to the OPR-1000 plant.

Summary: Quantitative assessment was conducted to analyze the impacts of climate change and human activities on marsh wetland in the Yellow River source region. The study used residual analysis and simulation models to evaluate the net primary productivity (NPP) of marsh wetland vegetation. The results showed that between 2000 and 2020, there was an increase in NPPa of marsh wetland vegetation, with climate change and human activities contributing to this increase. Human activities were found to have a significant impact on the decline of NPPa in certain areas.

Summary: Coastal marshes in Louisiana play a significant role in soil carbon accumulation and burial, affecting the global carbon budget. Saline marshes have lower total carbon density and accumulation rates compared to other marsh habitats. The total carbon burial rate in Louisiana in 2013 was estimated at 4.3 Tg TC yr(-1), with a potential significant impact on the global carbon budget if wetland loss continues.

Summary: Coastal saltmarsh restoration can efficiently store carbon and uptake greenhouse gases. Globally, saltmarshes store approximately 1.41-2.44 Pg carbon. Restored saltmarshes have low greenhouse gas emissions and rapid carbon accumulation, with the potential to offset up to 0.51% of global energy-related CO2 emissions.

Summary: The purpose of this study was to characterize the Molina de Aragon archaeological site in Guadalajara, Spain using gamma spectrometry. Different samples with historical influences were analyzed using gamma spectrometry and X-ray fluorescence to determine their chemical composition. Box-and-whisker plots, cluster analysis, and principal component analysis were used to study the activity concentration of radionuclides and evaluate sampling reproducibility. The results provided insights into the classification of areas based on different influences and identified least altered areas based on activity concentrations.

Summary: Root traits play a significant role in regulating plant growth and ecosystem functioning. This study found that the root traits of exotic Spartina alterniflora were more sensitive to changing soil nutrient availability compared to native Phragmites australis. Climate and soil nutrient availability had different effects on the productivity of the two species, with root traits playing a species-specific role in mediating these effects.

Summary: Wetlands, though vulnerable, provide multiple ecosystem services, especially carbon storage. Climate change may lead to large impacts on high-latitude wetlands, causing some wetlands to disappear and putting wetland organic carbon storage at risk. Predictions indicate that the southern Deyeuxia angustifolia communities will migrate northward in response to future climate changes, reducing the carbon sequestration capacity of wetlands.

Summary: Marshes in high plateaus play a critical role in governing the carbon cycle due to their large yet unstable soil organic carbon (SOC) storage. The Yarlung Zangbo River (YZR) is the world's highest river, and it harbors widespread alpine marshes and meadows with huge SOC storage but high vulnerability to climate change. This study systematically evaluated the effects of environmental factors on SOC storage along the YZR and found that climate, plant biomass, soil nutrients, and molecular features of organic matter all have significant impacts. The findings suggest that rising temperatures and decreased precipitation relative to temperature could have adverse effects on SOC storage in the future.

Summary: Phenology monitoring is important for understanding forest functioning and climate impacts. This research compares the phenological behavior of European beech forests using Tree-Talker (TT+) and Sentinel 2 satellite data. The study finds differences in the information derived by the two sensor types, particularly in terms of season length, phenology changepoints, and leaf period variability. TT+ with its higher temporal resolution demonstrates precision in capturing the phenological changepoints, especially when satellite image availability is limited.
