This study explores how altitude and the recovering period of patchily degraded meadow affect surface layer SOC and its forms in alpine meadow on the Qinghai-Tibet Plateau. The key pathways of environmental factors influencing SOC and its forms were determined via structural equation modeling (SEM). The results showed that SOC, light fraction organic carbon (LFOC), heavy fraction organic carbon (HFOC), dissolved organic carbon (DOC), easily oxidizable organic carbon (EOC) and particulate organic carbon (POC) exhibit negative correlations with elevation, whereas microbial biomass carbon (MBC) shows a positive correlation. SOC and its forms exhibit positive correlations with recovery length, SOC, LFOC, HFOC, DOC, MBC, EOC and POC increased by 20.67 %, 23.10 %, 20.64 %, 27.35 %, 36.98 %, 16.13 % and 33.62 % from 0.5 to 30 years. The content of SOC and its forms exhibited a significant downward trend (<em>P</em> &lt; 0.05) with elevation in a shorter period of recovery, over which SOC became more sensitive to altitude. Individually, recovery length is more important to SOC variation than altitude, but only after a certain threshold. Altitude regulates SOC dynamics via multiple mechanistic pathways. SEM showed that recovery length had a direct positive effect on DOC, MBC, POC, TC, and SC (path coefficients of 0.823, 0.715, 0.489, 0.879, and 0.586, respectively). Elevation had direct negative effects on SOC, temperature and soil water content (path coefficients of −0.674, −0.639, −0.808, respectively), while exhibiting direct positive effects on POC and precipitation (path coefficients of 0.388 and 1.127, respectively). Secondly, through precipitation, elevation specifically influenced DOC and MBC. Additionally, elevation indirectly affected DOC, POC and MBC by influencing temperature and precipitation. The spatial distribution of SOC content is regulated by altitude and ecosystem factors such as vegetation characteristics and soil physicochemical properties during the recovery of degraded patches. Therefore, vegetation restoration and artificial precipitation enhancement should be prioritized in the rehabilitation of patchily degraded alpine meadows. This study provides a theoretical foundation for SOC management in alpine meadows, and recommends implementing differentiated restoration measures across various elevational zones.</div></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":"256 ","pages":"Article 109135"},"PeriodicalIF":5.4,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143931545","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}

Soil matrix infiltration and total infiltration were measured using a surface-positioned double-ring infiltrometer, while preferential flow was quantified by subtraction. The soil infiltration process model applicability exhibited land-use dependency, which also reflected the variations in their infiltration mechanisms. Cumulative total infiltration (CTI, 380–3152 mm) and preferential flow (PFCI, 176–2755 mm) both followed: WL &gt; OL &gt; AL &gt; SFL &gt; CL, with PFCI contributing 42.8 % to 82.4 % of CTI. Cumulative matrix infiltration (CMI, 169–268 mm) followed: CL &gt; WL &gt; SFL &gt; OL &gt; AL, with CL showing the highest CMI contribution to CTI at 57.2 %, compared to 23.8 %, 22.0 %, 21.3 %, and 17.6 % for SFL, OL, WL, and AL, respectively. Total porosity was the primary factor promoting both matrix infiltration and preferential flow. Increasing silt and decreasing clay promoted matrix infiltration and inhibited preferential flow, enhancing soil water storage. Tillage impacted infiltration more than soil properties, resulting in CL exhibiting the highest matrix infiltration and the lowest preferential flow. To enhance soil and water conservation in karst landscape, we recommend allocating CL and OL to depressions and SFL and WL to hillslopes.

Vegetation in semiarid regions forms in patches, relying on runoff from bare-soil interpatches, but increased hydrological connectivity from vegetation loss can disrupt this balance. Microtopography influences these dynamics by shaping water and sediment flow patterns. However, limited empirical knowledge exists on the effects of microtopographic changes on vegetation performance. We examined the relations between the size of vegetated soil mounds, the soil organic carbon (SOC) in mounds and inter-mound areas, and the stress of the plants on the mounds for two grazing pressures in semiarid shrublands in Cyprus. We found that mound size increased with plant size, but plant size decreased with grazing pressure due to goat browsing. We thus normalized the mound size by the plant canopy size to study the variation in mound size related to the potential for sediment redistribution. Soil fertility and plant stress varied with the normalized mound size but grazing pressure altered these relations. In the lower-grazed site, larger mounds (relative to plant size) increased SOC in mounds, whereas in higher-grazed sites, they led to decreased SOC in both mound and inter-mound areas, as well as higher plant stress. Combined, our results suggest that larger mounds in low-grazed sites enhanced resource retention while larger mounds in high-grazed sites reduced resource availability and vegetation performance. These findings highlight a dual role of microtopography in dryland ecosystem functioning, especially under conditions of high erosion and grazing pressure. The role of mound development on plant performance in degrading hillslopes has been so far overlooked and deserves further investigation.</div></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":"256 ","pages":"Article 109121"},"PeriodicalIF":5.4,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143929637","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}

However, the optimal functionality of soil–water dynamics for rice cultivation, is constrained by poor soil fertility, waterlogging condition, or high soil salinity. Climatic variability, including unpredictable rainfall, droughts, and extreme weather, exacerbates these issues. Additionally, economic and social factors, including limited access to resources, labor shortages and market instability, further hinder farmerś ability to adapt, increasing mangrove swamp rice production (MSRP) vulnerability, threatening yields and food security. Soil characterization and suitability assessment serve as the foundational steps to investigate, describe, and identify constraints that small-scale farmers face daily in their production activities. In this study, soil profiles and nursery topsoils were described, sampled, and analyzed between 2022 and 2023 in three coastal areas and four villages of Guinea-Bissau, serving as study cases: Elalab (North), Malafu and Enchugal (Center), and Cafine (South). The physicochemical properties of soil were analyzed in the laboratory, and then subsequently utilized for classification and suitability assessment. Results revealed that soil profiles in the northern region exhibit structural limitations and low nutrient levels [nitrogen(N), phosphorus(P), potassium(K)] due to high sodicity concentration (&gt; 5 cmol (+) kg⁻¹), which consequently limit rice growth and yield. Conversely, soils in the southern and central regions show significant acidification and salinization, induced by reduction conditions and jarosite formation. Shallow nursery upland soils (Oio region, center) exhibit low nutrient content and water retention capacity, restricting seedling root growth. In conclusion, the establishment of enduring and adaptable strategies for innovative soil management practices in MSRP demands bridging farmers’ traditional agricultural knowledge and practices with scientific insights. Innovations will be produced through the systematic collaboration between experts, scientists and farmers, who will share observations, experiences and knowledge to foster the development of nature-based solutions.</div></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":"256 ","pages":"Article 109131"},"PeriodicalIF":5.4,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143921772","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}

In this study, we analyze distributions of branched glycerol dialkyl glycerol tetraethers (brGDGTs) in the sediments of Girraween Lagoon from northern Australia to investigate the temperature and hydroclimate changes spanning the past 10.4 ± 0.1 kyr. Our reconstructed Holocene mean annual air temperature using the tropical lake-specific brGDGT calibration displays a long-term warming trend with amplitude of 2 °C. This overall warming pattern is generally consistent with other brGDGT-based terrestrial temperatures, alkenone-derived sea surface temperatures from the tropical Australasia and model simulations, but not with those inferred from planktonic foraminiferal Mg/Ca paleothermometers. The reconstructed pH values suggest a significant acidification process in Girraween Lagoon during the Holocene, which mainly results from a reduction in the input of alkaline waters from the underlying carbonate sinkhole regulated by hydroclimate change in northern Australia, but also an enhancement of acid production from sedimentary organic matter. Combined with other proxy records, we suggest that changes in the El Niño-Southern Oscillation have played an important role in the transition from a cool and wet to a warmer and seasonal drier climate in tropical Australasia over the Holocene.
