Understanding the processes and factors influencing carbon accumulation is critical for elucidating the principles governing peatland carbon dynamics, thereby supporting global climate change mitigation efforts. This study reconstructed the carbon accumulation history of the Sihe (SH) peatland, a minerotrophic fen in the Changbai Mountains of northeastern China, over the past 2200 years. Carbon stable isotopes (δ¹³C) of α-cellulose in <em>Carex</em> spp. and grain-size-sensitive components were identified as effective indicators of peatland moisture and hydrological conditions, whereas plant macrofossil analysis was performed to track the temporal changes in vegetation composition. The results indicated that the moisture condition and hydrological supply in the SH peatland have exhibited a declining trend over the past 2200 years, reflecting a strong sensitivity to centennial-scale variations in precipitation and humidity within the Changbai Mountains. During the Roman Warm Period (RWP) and the Dark Age Cold Period (DACP), despite higher summer solar insolation, greater seasonality, elevated regional temperatures, and abundant precipitation, the CAR in the SH peatland remained relatively low. This suggested that the influence of climate on CAR was constrained by other factors. During the Medieval Warm Period (MWP) and Little Ice Age (LIA), climate had a pronounced impact on CAR. Under warm and humid conditions, peatlands exhibited an elevated CAR, whereas the cold and arid conditions of the LIA led to a significant decline. Notably, the CAR of the SH peatland demonstrated no significant response to local moisture, indicating a complex relationship between hydrological conditions and carbon accumulation dynamics. This study emphasized that climate could not always be the primary driver of CAR in peatlands, with vegetation composition and local autogenic processes playing critical roles. However, the influence of climate on carbon accumulation dynamics may intensify as the peat layers accumulate.</div></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":"255 ","pages":"Article 109056"},"PeriodicalIF":5.4,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143833402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we leverage the negligible content of organic-complexed Fe and Al in three Podzol profiles from Ilha Comprida (Southeastern Brazil) to determine the particle size distribution and sedimentary structures inherited from the parent material that enhances podzolization. The investigated Podzols have unique sequences of sedimentary facies, i.e., a body of sediments with a specific combination of mineral assemblages, fabrics, grain size, and depositional or penecontemporaneous structures, both biological and physical, reflecting specific depositional processes. Our results indicate that podzolization via DOM retention increases in response to two hydrologic mechanisms: (i) <em>capillary break</em> at the interface of sedimentary facies with a mean sand size of 2.6 ± 0.3 phi (small pores) over a layer of a mean sand size of 1.9 ± 0.2 phi (large pores); and (ii) <em>physical barrier</em> for vertical water percolation at the abrupt textural transition between sandy-over-clayey sedimentary facies.

While machine learning techniques have been widely applied to LSA with notable progress, they face limitations in LSA precision, and struggle to capture micro-topographic features with multi-points instead of single one in slope units. To address these limitations, this study proposes an LSA model based on contour topographic features and Graph Convolution Networks (ConToGCN). First, the graph structure for each slope unit is built by generating nodes and edges from contour lines. Next, 9 factors, including elevation, are extracted for graph nodes using feature engineering, and the steepness between nodes is calculated to identify critical features such as steep scarps and flow zones. The ConToGCN model is then developed to aggregate adjacent node features and generate landslide probability. Changxing County in Zhejiang, China, was selected as the study area. A dataset comprising 124 landslide and 124 non-landslide samples was collected, with 70% used for training and 30% for testing. A comparative performance evaluation was conducted against Graphormer, a GCN model based on slope unit centroids (CentGCN), Random Forest (RF), and Support Vector Machine (SVM). The results demonstrate ConToGCN model outperforms these other models, with an area under the ROC (AUROC) of 0.93 and an area under the PR curve (AUPR) of 0.94. This represents improvements of 14.81% and 14.63% over the SVM model, respectively. The ConToGCN model effectively captured the complex topographic structures and improved the LSA precision significantly. We believe the model provides a novel approach to landslide disaster prevention and mitigation.</div></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":"255 ","pages":"Article 109029"},"PeriodicalIF":5.4,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143837925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a multi-proxy approach, including pollen and plant macrofossil data, stable carbon and oxygen isotopes, and grain size distributions, we assess the impact of local hydrological conditions on sedimentation and climatic signals. Biogenic sequences record vegetation succession and climatic fluctuations throughout the Eemian, with Kozłów preserving a more continuous archive, whereas Struga exhibits hydrological instability affecting depositional patterns. Pollen data enabled the identification and detailed characterisation of regional pollen assemblage zones (RPAZ), facilitating correlations with regional frameworks across Western and Eastern Europe. Isotopic records at Kozłów indicate evaporative enrichment linked to river inflow and intensified evaporation. In contrast, Struga functioned as a closed basin, with prolonged water residence time and isotope values reflecting internal hydrological balance. Grain size results highlight contrasting sedimentation regimes, with Kozłów showing a transition towards coarser material, suggesting growing fluvial influence, while Struga reveals episodic hydrological fluctuations within a closed-lake system. Climate reconstructions using PPPbase indicate pronounced seasonality and shifts in precipitation patterns during the interglacial. Our findings underscore the contrasting hydrological regimes of Kozłów and Struga, illustrating how local geomorphology and water balance shaped lake evolution. The palaeobotanical record further enhances understanding of catchment dynamics.

The aim of this work is to determine the influence of selected temperature conditions on soil surface deformation caused by the splash phenomenon at the initial stage of erosion. The goal was achieved by measuring the morphology of craters formed by the impact of a single drop. The research included the use of three soils varying in particle size distribution: loamy sand, sandy loam, and silty loam. Additionally, the work took into account two variants of initial soil moisture and three temperature conditions (including various temperatures of soil, air, and drop-forming water). The measurements were taken with a 3D scanner, determining depth, equivalent diameter, volume of the craters, and a dimensionless parameter α (depth-to-diameter ratio). Temperature effects were observed in silty loam, where craters became wider (from average diameter of 9.41 ± 0.31 to 10.47 ± 0.21 mm for pF = 1) but shallower (from average depth of 1.28 ± 0.05 to 1.00 ± 0.05 mm for pF = 1) with increasing temperature, and in loamy sand, where temperature influenced the differences in diameter and volume of craters formed between varying moisture conditions. The differences in crater morphology could be due to the influence of temperature on the viscosity and surface tension of water, which may have led to a change in susceptibility to deformation.

To address this gap, we constructed a global database of fire-induced soil changes, which includes data from 253 studies (1,896 observations of grassland soil properties and 3,425 observations of forest soil properties). We found that, globally, fire increased soil bulk density (BD), pH, and available phosphorus (AP) by 1.1–17.9 %, while it decreased soil water content (SWC), mean weight diameter (MWD), soil respiration (SR), soil total carbon (TC), total nitrogen (TN), soil organic matter (SOM), and the C/N ratio by 3.7–22.9 %. In forests, soil properties were more strongly affected by fire compared to grasslands, with effect sizes 1.02–32.0 times greater, except for soil potassium and magnesium, which exhibited contrary changes. Variation partitioning indicated that fire-induced soil changes in forests were explained by geoclimatic conditions (72.1 %) and fire characteristics (24.3 %), whereas in grasslands, the soil changes were predominantly explained by fire characteristics (79.1 %) rather than geoclimatic conditions (15.4 %).
