Summary: Understanding the spatial distribution of urban forest ecosystem services is crucial for urban planning and sustainable development. This study used the i-Tree Eco model and kriging interpolation to quantify and map the services in Zhengzhou, China. The results showed significant spatial heterogeneity, with higher ecosystem services in watershed and woodland areas. This study provides a basis for future urban construction and management, contributing to improved ecosystem services and the health of urban residents.

Summary: This study investigated the spatial distribution of phytoliths and PhytOC in wheat ecosystems and found that soil physiochemical factors and climate factors have a positive impact on the production of phytoliths and PhytOC. The estimated PhytOC storage in wheat ecosystems is significant and plays an important role in mitigating climate warming.

Summary: The destruction of vegetation structure and quantity weakens the carbon sequestration capacity of the ecosystem. Building an ecological spatial network is an effective method for studying vegetation distribution structures, but the relationship between vegetation spatial distribution structure and carbon sequestration through complex network theory perspective is understudied. This study investigates the eco-space network and vegetation spatial structure characteristics in the ecologically sensitive area of the middle reaches of the Yellow River. The study provides insights into optimizing vegetation distribution and enhancing carbon sequestration capacity.

Summary: Orchards have a high potential for carbon sequestration, but research on their spatial variability at catchment scale and the difference between tree areas and lanes is lacking. In a Southern Spain catchment with olives on a vertic soil, we analyzed the spatial variability of soil organic carbon stock (SOCstock) at 90 cm depth. Results showed higher SOC concentration in the tree area compared to the lane up to 60 cm depth, but this had negligible impact on SOCstock due to higher soil bulk density in the lane. The overall SOCstock of the orchard was 4.14 kg m-2, similar to other intensive field crops and agroforestry under comparable rainfall conditions.

Summary: In the Bering Sea, surface waters are oversaturated with aragonite due to high biological removal, while subsurface waters show generally low saturation states and even strong undersaturation, likely caused by remineralization. Despite being relatively low, aragonite saturation states in the shallow nearshore regions of the Bering Sea remain above the saturation horizon throughout the water column, possibly due to high local primary production. Ocean acidification in the Bering Sea is influenced not only by natural processes, but also by the accumulation of anthropogenic CO2, a result of climate change.

Summary: This study investigates the pros and cons of six popular sediment transport capacity methods for soil erosion/deposition simulation at watershed scales. The KR and EH methods outperformed others by producing more accurate sediment concentration predictions. Erosion mainly occurred upstream of watersheds with steep slopes and unbalanced initial sediment concentrations, while deposition typically appeared in flat terrain areas.

Summary: Gully erosion in southern Iran poses a threat to local communities, with the QUEST model demonstrating superior predictive performance compared to conventional statistical models. The model offers a practical and adaptable susceptibility map, highlighting the need for pragmatic mitigation plans in highly susceptible areas. Further studies on machine learning models for gully erosion are warranted.

Summary: Understanding the spatial variability of soil organic carbon (SOC) and its main influencing factors is crucial for sustainable land use management and climate change mitigation. Results show that elevation and vegetation coverage have significant positive effects on SOC, while wind erosion and deposition can alter SOC content and increase its spatial variability. SOC exhibits spatial autocorrelation and varies with land uses.

Summary: The Hassink (1997) equation was found to inaccurately predict the maximum fine-fraction OC in UK grasslands, with Quantile Regression (QR) estimates significantly higher than Linear Regression and Boundary Line (BL) analysis. Sward age had inconsistent effects on measured variables and potential maximum fine-fraction OC, highlighting the need for accurate methods in predicting carbon sequestration potential.

Summary: Understanding forest functioning is crucial for sustainable ecosystem services, with a focus on carbon sequestration potential and nutrient stoichiometry in Uttarakhand, India. The study found that nitrogen, phosphorus, and organic carbon content in forest soil increased with altitude, while stoichiometric ratios remained consistent. Soil carbon sequestration potential varied across tree species, indicating Abies pindrow > Cedrus deodara > Quercus leucotrichophora > Pinus roxburghii. This information aids in forest management and mitigation strategies.

Summary: This paper aims to establish a general framework for shallow foundation to quantify the influence of stratum uncertainty on bearing capacity. Geological uncertainty is simulated using Markov random field, while spatial variability is characterized using random field theory. Shenzhen Mawan's borehole data and soil properties are adopted as an example to illustrate the proposed framework. Reduction factor and contribution rate indicator are developed to evaluate the impact of uncertainties.

Summary: This study created an updated rainfall erosivity map for Austria and its main agricultural production zones based on a larger number of rainfall stations and a recent time series. The study identified differences in temporal and spatial distribution of rainfall erosivity, erosion index, and erosivity density, indicating areas at risk of soil erosion and vulnerability. The significantly larger number of rainfall stations and an updated time series increased the representativeness of rainfall erosivity estimation in Austria, contributing to a more precise soil erosion risk assessment.

Summary: This study examines the debate surrounding the extent of forest coverage in the central highlands of Madagascar and analyzes the carbon and sediment dynamics of grassland and forest soils. The study finds that grassland soils have lower organic carbon content compared to forest soils, and that the grasslands have developed on soils previously dominated by C-3 plants. Additionally, the grasslands in valley positions contain more recent grass-derived organic carbon, likely due to higher productivity and erosion.

Summary: The study used a geothermal gradient in Canada to investigate the warming effects on soil organic matter in a forest ecosystem, finding that soil organic carbon responded similarly to warming in both topsoil and subsoil. There was a negative relationship between soil temperature and whole-profile SOC stocks, with the largest share of total SOC losses coming from POM-C. Losses in N were not observed, indicating a redistribution with accumulation in the silt and clay fraction.

Summary: The study found that the warming caused by climate change in the northern circumpolar permafrost region has allowed agricultural production to expand, leading to the conversion of forests to arable land. This conversion has resulted in the loss of soil organic carbon (SOC) that was previously protected by frozen ground. The interaction between permafrost abundance and deforestation on SOC stocks has been poorly studied. The study sampled soils from both permafrost and non-permafrost areas to assess the impact of land-use change on SOC stocks. It found that the conversion of permafrost-affected forest soils to cropland and grassland resulted in significant SOC losses, while sites without permafrost did not show significant changes. The fate of SOC after land-use change depended on the abundance of permafrost, with climate conditions playing a major role. The study suggests that considering the initial conditions of forest soils is important to minimize climate impact in regions with discontinuous permafrost.
