Here we present a continental-scale study on soil microbiomes of ten forests in China, spanning latitudes from 18°54′N to 50°48′N, resulting in a comprehensive catalog of bacterial and fungal operational taxonomic units (OTUs). Both bacterial and fungal communities exhibited discernible spatial variations in taxonomic and phylogenetic diversity. The composition of bacterial communities varied distinctively due to climatic zones—cold temperate, temperate, subtropical, and tropical—whereas fungal communities did not exhibit such pronounced distinctions. The co-occurrence network complexity of bacterial communities displayed a decremental trend along the cold temperate, temperate, subtropical, and tropical zones, whereas that of fungal communities displayed an incremental pattern. These results may be attributed to the facts that low temperatures sustain a high biomass of bacteria and foster increased interactions, while high temperatures and precipitation stimulate fungi-plant interactions. Furthermore, community assembly modeling revealed that forest soil microbial communities were dominated by stochastic processes. The bacterial community structure was mainly driven by homogeneous selection (26–41%) and dispersal limitation (35–44%), whereas dispersal limitation (51–56%) had the greatest impact on fungal community structure. Notably, bacterial functional genes associated with carbon fixation were more abundant in cold temperate soils compared to tropical soils. This study sheds light on spatial variations of forest soil microbiomes in China, enhancing further understanding of their response to global changes and implications for soil organic carbon cycles.</p></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141954130","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}

Existing research on glacial lake changes primarily concentrates on specific regions or decadal timescales, impeding a comprehensive understanding of the spatial and temporal variation of glacial lakes. This study tracks the annual evolution of global glacial lakes larger than 1 km² (totally 3,133) from 2013 to 2022 based on Landsat OLI imagery. We investigated the lake area variation and glacier mass balance to explore interactions between glacial lake expansion and glacier mass loss. We aim to reveal the potentially diverse changes in the area of glacial lakes in various regions and of different types over the past decade. Our results show that, for the study glacial lakes, the total area has increased remarkably from 14,612 ± 21.13 km² to 15,034 ± 18.54 km² from 2013 to 2022. Among them, the glacier-contacted lakes experienced a rapid increase from 6,220 km² to 6,625 km², contributing to ∼ 96 % of the net area increment of the glacial lakes worldwide, whereas non-glacier-contacted lakes remain relatively stable at approximately 8,400 km². Overall, glacier-contacted lakes grew relatively fast in the sub-periods of 2013–2014 and 2018–2019 and maintained slightly slow growth in other years. Remarkable expansion of glacial lakes was observed in Alaska, Iceland, and New Zealand. The significant expansion of glacier-contacted lakes was primarily attributed to the water inundation sprawl upward to the glacier tongues, which accelerated melting rates of the mother glaciers as feedback. Our analysis of the trend and inter-annual variation of glacial lake area reveal contrasting evolution of glacial lakes in different regions and of different types, which serves as a key reference for comprehending the impact of climate change, the interaction between glaciers and glacial lakes, and mitigating natural disasters like glacial lake outbursts.</p></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141946361","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 calibrated the Hydrus-1D model in a data-rich monitoring area of Mu Us Sandy Land to explore the differences in liquid and water vapor transport processes between bare land (BL) and shrubland (SL), then elucidate the regulatory mechanisms of sparse shrubs on soil water flux during the dry period. The result showed that shrubs regulated and remolded the soil hydrological processes, significantly changing the soil water transport pattern, prompting the liquid and water vapor flux to be continuously transported to the vicinity of the root zone (30–120 cm). Specifically, during the dry period, SL has multiple divergent zero-flux planes, mainly located at 0–30 cm depth of the ground. However, due to transpiration demand and soil temperature lag caused by the canopy, the liquid and water vapor flux below the zero-flux plane of SL constantly moved to the root zone, resulting in its soil water flux exhibiting the consistent downward cumulative flux in liquid and water vapor, accounting for 63% and 36% of the total water flux. In contrast, the BL's zero-flux plane was 60–75 cm inside the soil. The liquid water flux constantly migrated from the zero-flux plane up to the ground during the day and night. While the water vapor flux transferred to the zero-flux plane during the day and inverse at night. Therefore, the cumulated upward liquid and downward water vapor flux were dominated in the BL, accounting for 62% and 21% of the total water flux, respectively.

To examine the effects of residue decomposition on the microbial contribution to SOC, and how microbial groups (¹³C-phospholipid fatty acids (PLFAs)) and soil enzymes regulate necromass accumulation (¹³C-amino sugars) and SOC, a 163-d decomposition experiment with ¹³C-enriched aboveground residue of <em>Stipa bungeana</em> was conducted. The δ¹³C value of above-ground residue decreased whereas that of soil increased, thus providing direct evidence for the contribution of residue-derived C to SOC. Residue-derived ¹³C in SOC, microbial biomass C, and dissolved organic C increased during decomposition. The soil microbial groups shifted from gram-negative to gram-positive bacteria and actinobacteria upon decomposition. C-cycling enzyme activity increased as decomposition proceeded. Bacterial necromass dominated in the early decomposition stage, fungal necromass dominated thereafter, and the total necromass increased with decomposition. The SOC and necromass were significantly correlated with residual mass, the residue C to nitrogen (N) ratio, and ¹³C-arbuscular mycorrhizal fungal (AMF) PLFAs. By incorporating aboveground grassland residues into the soil, microorganisms regulate soil enzyme activity, control residue-derived C through the soil food chain and facilitate the transformation of microbial products into SOC through microbial anabolism. Our findings underscore how variations in the residue decomposition stage shape the primary microbial groups, influencing enzyme activity that, in turn, determines necromass turnover, and thus SOC formation.</p></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141946363","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}

While the decrease in water levels during shrub encroachment into peatlands is known to increase soil carbon emissions, the role of the genetic potential of microbial metabolic processes mediated by root exudates in affecting rhizosphere soil carbon emissions is less well understood. Here, we conducted in situ field monitoring of shrub and herb peatlands, combined with laboratory incubation experiments involving the addition of root exudates. Using metagenomics and metabolomics technologies, we aimed to elucidate the microbiological mechanisms behind changes in carbon emissions. This study found that the rhizosphere soil under shrubs had a higher CO₂ emission rate with greater genetic potential for CO₂ production (19.36%), but exhibited a lower CH₄ emission rate conferring a lower genetic potential for CH₄ production (52.30%) than that under herbs. These differences were attributed to the distinct ways in which the root exudates of shrubs and herbs influence the structure and function of the microbial community, thereby favoring CO₂ and CH₄ emissions differently. Specifically, the relatively higher amounts of sugars and amino acids in shrub root exudates stimulate the genetic potential for cellulose and hemicellulose decomposition, leading to a 13.23% increase in CO₂ emissions. In contrast, the relatively higher amounts of lipids in herb root exudates promote the genetic potential for the acetic acid-type methanogenic process, resulting in a 33.50% increase in CH₄ emissions. Shrubification increased the genetic potential for labile carbon decomposition while decreasing the genetic potential for chitin and lignin decomposition, possibly promoting recalcitrant carbon conservation in the rhizosphere soil. Altogether, shrubification of herbaceous peatlands increases rhizosphere soil carbon emissions by regulating root exudates. It is recommended that appropriate ecosystem management measures be implemented to control shrub expansion, thereby optimizing carbon emissions from peatlands.</p></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141946364","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}

It is important to understand the hydrodynamic mechanism of slope covered by both vegetation and BSC to clarify the water erosion dynamics. However, the coupling effects of vegetation and BSC on overland flow characteristics are still unclear. In this study, simulated rainfall was employed to explore the effects of different combinations of grasses, shrubs and BSC on the hydrodynamic characteristics of flow. The results showed that grasses, shrubs, BSC and vegetation combinations significantly reduced the flow velocity. Compared with the control check (CK), the flow velocities of the more BSC (MBSC), grass cover (GC) and shrub cover (SC) treatments were reduced by 50 %, 32 % and 14 %, respectively. The detention coefficient of different treatments increased with increasing BSC coverage. This result indicated that BSC played a dominant role in slowing the flow velocity under low-cover vegetation. The Froude number (<em>Fr</em>) of CK, GC, SC, and SC+GC were &gt; 1 during rainfall, indicating supercritical flow. The average <em>Fr</em> of the other treatments was &lt; 1, but <em>Fr</em> &gt; 1 was found in the less BSC (LBSC) and SC+LBSC treatments. The total flow resistance under different vegetation combinations did not conform to the simple linear stacking relationship. The interaction effect between different covers generated additional resistance, which varied among different ground cover combinations. The relationship between resistance coefficient (<em>f</em>) and Reynolds number (<em>Re</em>) gradually changed from a negative correlation for bare slopes to a positive correlation when vegetation or BSC existed, indicating that form resistance played a dominant role. It was concluded that BSC had a dominant effect on the hydraulic characteristics of overland flow in all ground cover treatments.

The C:N and N:P ratios increased and decreased with soil depth, respectively, while the C:P ratios showed no significant changes with soil depth.

The C:P ratios in bulk soils and all fractions significantly increased with increasing AI for the surface soil layers, but first increased and then decreased with increasing AI in the deep soil layers. N:P ratios in bulk soils and all fractions were positively related to increasing AI along the transect, but the growth rate slowed in wetter areas with a threshold at an AI value of 0.2. Across the transect, C:N ratios in bulk soils were positively related to clay contents in all soil layers, while N:P ratios in bulk soils were positively related to clay contents only in deep soil layers.

In this study, the all-year-round CO₂ fluxes from the flatland, gully sidewalls and terrace sidewalls were monitored <em>in-situ</em> in a gully-dominated catchment on the Chinese Loess Plateau. The instantaneous responses of CO₂ fluxes to bank failure and drying-rewetting cycles were further examined by manual detachment and rainfall simulation. We observed that: 1) The sidewalls emitted CO₂ in all seasons, from warm rainy summer to freezing dry winter. The average CO₂ emission rates from the sidewalls reached 26% of that from the flatland, even though the soil organic carbon, dissolved organic carbon and soil microbial biomass carbon content of the barren soil on the sidewalls was disproportionally lower as 57%, 44%, and 76% of that on the flatland. 2) The simulation of bank failure and drying-rewetting cycles could rejuvenate the sidewalls and thus enhance the CO₂ emission rates, respectively by 49%, 27%, and collectively by 82%. 3) Based on the digital terrain model developed from the imagery acquired by the unmanned aerial vehicle, the actual exposed area of the study site was 46% larger than its ortho-projected area. This not only challenges the plausibility of conventional orthographic projection to estimate the actual soil surface area in similar regions predominated with eroded scarps and bench terraces, but also highlights the non-negligible contributions from lateral CO₂ emissions to local carbon source strength. The vigorous responses of lateral CO₂ emissions to soil water, temperature and layer detachment further emphasize the vulnerability of bank failure, which may potentially introduce more exposed area and thus trigger more CO₂ fluxes under future climate conditions. Therefore, the lateral CO₂ emissions from steep slopes or eroded scarps should not be ignored but deserve systematic investigations in complex terrains similar to the Chinese Loess Plateau.</p></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141946287","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}
