Purpose

Carbonate components in soils and sediments play a crucial role in the study of surface processes and the reconstruction of paleoclimates. The extraction of carbonate components from soils and sediments is often carried out using different types of acids. However, which reagents can effectively extract the carbonate components while minimizing the destruction of non-carbonate minerals in soils and sediments has not been fully explored yet.

Methods

The present study conducted a series of conditional leaching experiments on six standard soil and sediment samples with diverse geological backgrounds and varying carbonate contents.

Results

The results revealed that dilute acetic acid (HOAc, 0.5 mol/L) performed better than acid solution (HCl) and acetic acid buffer solution (NaOAc-HOAc) in promoting the complete dissolution of carbonate minerals and avoiding the dissolution of clay minerals. It was also observed that pre-treating the samples with neutral ammonium acetate buffer solution (NH₄OAc) or potassium chloride buffer solution (KCl) was necessary to remove exchangeable components. The Mg/Ca ratios of the silicate components after leaching carbonate in the standard soil and sediment samples we used exhibited significant differences (ranging from 0.41 to 1.60).

Conclusion

The dilute acetic acid (HOAc, 0.5 mol/L) is advisable for the extraction of carbonate components from soils and sediments, and the pre-treatment of removing exchangeable components is essential for samples with low carbonate content. It is more reasonable to use the element ratios of the dilute acid insoluble fraction or the average compositions of minerals in soils and sediments for individual correction for the contribution of the silicate components.

目的土壤和沉积物中的碳酸盐成分在研究地表过程和重建古气候方面起着至关重要的作用。从土壤和沉积物中提取碳酸盐成分通常使用不同类型的酸。本研究对六种具有不同地质背景和不同碳酸盐含量的标准土壤和沉积物样品进行了一系列条件浸出实验。结果结果表明，稀醋酸（HOAc，0.5 mol/L）比酸性溶液（HCl）和醋酸缓冲溶液（NaOAc-HOAc）更能促进碳酸盐矿物的完全溶解，避免粘土矿物的溶解。此外，还发现用中性醋酸铵缓冲溶液（NH4OAc）或氯化钾缓冲溶液（KCl）对样品进行预处理对于去除可交换成分是必要的。结论用稀醋酸（HOAc，0.5 mol/L）萃取土壤和沉积物中的碳酸盐成分是可取的，而去除可交换成分的预处理对于碳酸盐含量低的样品是必不可少的。使用稀酸不溶部分的元素比率或土壤和沉积物中矿物的平均成分对硅酸盐成分的贡献进行单独校正更为合理。

Purpose

The interplay between microbial taxonomy, functional diversity, and land-use changes across diverse ecosystems must be better understood. This study explores, through a statistical modeling approach, the intricate relationships between microbial communities, soil properties (nutrient contents and physicochemical parameters), and land-use changes, using stable isotopes ratio (δ¹³C/δ¹⁵N) as ecosystem function indicator.

Methods

Using Structural Equation Modeling (SEM) this study aims to investigate how soil microbial communities, soil properties and ecosystem function are interconnected in three ecosystems undergoing land-use change in Nevado de Toluca, Mexico.

Results

Multivariate analyses of microbial communities and soil parameters for the different land-uses reveal significant variation in both microbial composition and soil properties (i.e. nutrient contents) mainly explained by the land-use history of the studied ecosystems. Through the SEM approach, it was possible to disentangle the relative contribution of land-use change, microbial community composition and nutrient contents to the ecosystem function defined as the δ¹³C/δ¹⁵N ratio.

Conclusions

Microbial communities are the main drivers of soil ecosystem functioning. However, through SEM approach it is possible to formally test direct and indirect relationships impacting microbial communities and the resulting functional consequences, contributing to a mechanistic understanding of the ecological implications of land-use change, aiding in sustainable land-use decision-making.

目的必须更好地了解不同生态系统中微生物分类、功能多样性和土地利用变化之间的相互作用。本研究以稳定同位素比值（δ13C/δ15N）作为生态系统功能指标，通过统计建模方法探讨微生物群落、土壤特性（养分含量和理化参数）以及土地利用变化之间的复杂关系。方法本研究采用结构方程建模（SEM）方法，旨在研究墨西哥内瓦多-德-托卢卡（Nevado de Toluca）三个正在经历土地利用变化的生态系统中，土壤微生物群落、土壤特性和生态系统功能是如何相互关联的。结果对不同土地利用下的微生物群落和土壤参数进行多元分析后发现，微生物组成和土壤特性（即养分含量）都存在显著差异，这主要是由所研究生态系统的土地利用历史造成的。通过 SEM 方法，有可能将土地利用变化、微生物群落组成和养分含量对生态系统功能（定义为 δ13C/δ15N 比率）的相对贡献区分开来。然而，通过 SEM 方法可以正式检验影响微生物群落的直接和间接关系以及由此产生的功能后果，有助于从机理上理解土地利用变化对生态的影响，有助于可持续的土地利用决策。

Purpose

Although the combined plant-biochar remediation in improving soil contaminated by polycyclic aromatic hydrocarbons (PAHs) is considered efficient (Singha and Pandey in Crit Rev Biotechnol 41:749–766, 2021), the potential for application remains poorly known. This study used clones of Buchloe dactyloides to evaluate the effects of biochar on the capability of phytoremediation and rhizosphere soil contaminated with PAH.

Materials and methods

Pot experiments were conducted to assess the effects of biochar on growth physiological parameters of B. dactyloides growth, accumulation of PAHs in B. dactyloides, and soil environment.

Results and discussion

The results showed that the application of biochar increased the levels of antioxidants (free proline, glutathione, and ascorbic acid), antioxidant enzymes (catalase and laccase), and phytohormones (abscisic acid, indole acetic acid, jasmonic acid, salicylic acid, and gibberellin), decreased the accumulation of reactive oxygen species and lipid peroxidation in the roots, thereby enhancing the antioxidant defense ability and improving PAHs tolerance in roots of B. dactyloides. Moreover, the activities of enzymes (catalase, dehydrogenases, urease and protease) and soil nutrients in the rhizosphere soil were significantly increased, the content of PAHs decreased, and the health of the rhizosphere soil was improved.

Conclusions

Biochar treatment promoted the accumulation of PAHs, improved soil environment and significantly enhanced the effects of phytoremediation. Therefore, the combined application of B. dactyloides and biochar can be considered as a feasible approach for the phytoremediation of PAH-contaminated soil.

目的虽然植物-生物炭联合修复被多环芳烃（PAHs）污染的土壤被认为是有效的（Singha 和 Pandey 在 Crit Rev Biotechnol 41:749-766, 2021 中），但其应用潜力仍鲜为人知。本研究利用 Buchloe dactyloides 的克隆来评估生物炭对植物修复能力和多环芳烃污染的根瘤土壤的影响。材料和方法进行了盆栽实验，以评估生物炭对 B. dactyloides 生长的生理参数、B. dactyloides 中多环芳烃的积累以及土壤环境的影响。结果与讨论结果表明，施用生物炭提高了抗氧化剂（游离脯氨酸、谷胱甘肽和抗坏血酸）、抗氧化酶（过氧化氢酶和漆酶）和植物激素（脱落酸、吲哚乙酸、茉莉酸、水杨酸和赤霉素）的水平，减少了根中活性氧的积累和脂质过氧化，从而增强了根的抗氧化防御能力，提高了根对多环芳烃的耐受性。dactyloides根系对多环芳烃的耐受性。此外，根瘤土壤中酶（过氧化氢酶、脱氢酶、脲酶和蛋白酶）和土壤养分的活性显著提高，多环芳烃含量降低，根瘤土壤的健康状况得到改善。因此，在多环芳烃污染土壤的植物修复中，联合应用 B. dactyloides 和生物炭是一种可行的方法。

Purpose

Soil salinization severely hinders the development of agriculture. Pristine biochar (BC) has a considerable impact on improving soil quality and maximizing crop yield. However, applying biochar has the risk of aggravating soil salinization. Acid-modified biochar may have a good effect on the improvement of saline-alkali soil.

Methods

Nitric acid and phosphoric acid were used to modify the pristine biochar (BC). The pristine biochar (BC), nitric acid-modified biochar (NC) and phosphoric acid-modified biochar (PC) were used at 1%, 2%, and 3% (w/w), respectively. There were ten treatments in total: CK, BC₁, BC₂, BC₃, NC₁, NC₂, NC₃, PC₁, PC₂, and PC₃.

Results

Our results indicated that the application of biochar further aggravated soil salinization. Soil pH and EC significantly increased by 0.08–0.42 units and 215.51–362.07 μS.cm⁻¹, respectively. Additionally, the BC application reduced the activities of C-, N- and P-acquiring enzymes in saline-alkali soil. Compared with BC, NC and PC decreased the alkaline metal elements by 84.34% and 79.29%, respectively, and enhanced the specific surface area. Acid-modified biochar significantly reduced the content of Na⁺, Cl⁻, SO₄²⁻, CO₃²⁻ and HCO₃⁻. Meanwhile, the application of acid-modified biochar reduced soil pH and EC by 0.16–0.59 units, 228.38–788.93 μS.cm⁻¹, respectively. Furthermore, the application of acid-modified biochar enhanced N fixation ability and the activity of C-acquiring enzymes and P-acquiring enzymes.

Conclusions

The application of pristine cotton straw biochar will further aggravate soil salinization, thereby inhibiting the soil enzyme activities. In contrast, acid-modified cotton straw biochar can reduce soil salinity, improve soil available nutrients and also enhance the enzymatic activities, which is advantageous to the restoration of saline-alkali soil.

目的土壤盐碱化严重阻碍了农业的发展。纯净的生物炭（BC）对改善土壤质量和最大限度地提高作物产量有很大影响。然而，施用生物炭有可能加剧土壤盐碱化。方法用硝酸和磷酸对原始生物炭（BC）进行改性。原始生物炭（BC）、硝酸改性生物炭（NC）和磷酸改性生物炭（PC）的使用浓度分别为 1%、2% 和 3%（重量比）。结果表明，施用生物炭进一步加剧了土壤盐碱化。土壤 pH 值和 EC 值分别明显增加了 0.08-0.42 个单位和 215.51-362.07 μS.cm-1。此外，施用 BC 还降低了盐碱地中 C、N 和 P 获取酶的活性。与 BC 相比，NC 和 PC 分别减少了 84.34% 和 79.29% 的碱金属元素，并增加了比表面积。酸改性生物炭显著降低了 Na+、Cl-、SO42-、CO32- 和 HCO3-的含量。同时，施用酸改性生物炭后，土壤 pH 值和 EC 值分别降低了 0.16-0.59 个单位、228.38-788.93 μS.cm-1。结论原生棉秆生物炭的施用会进一步加剧土壤盐碱化，从而抑制土壤酶的活性。相比之下，酸改性棉秆生物炭能降低土壤盐渍化程度，提高土壤可利用养分，还能增强酶的活性，有利于盐碱地的修复。

Purpose

The invasive plant Flaveria bidentis (L.) Kuntze, known as the "ecological killer", poses a significant threat to the ecosystem stability due to its strong phenotypic plasticity and high fertility. Previous studies have reported a close relationship between plant invasion and soil microbial communities. This study aimed to gain a deeper understanding of the relationship between the invasion of F. bidentis, the diversity of soil microbial communities, and soil physiochemical properties.

Methods

In this study, we established a common garden experiment by planting F. bidentis and Chenopodium ficifolium Sm. separately and mixed, in Lanfang, China. We analyzed microbial communities in both bulk soil and rhizosphere soil using the high-throughput sequencing technology.

Results

The results showed that F. bidentis invasion significantly increased bacterial and fungal diversities in rhizosphere soil, irrelevant with or without the existence of native plant species. Meanwhile, F. bidentis increased the content of organic matter and ammonium nitrogen (NH₄⁺) in bulk soil and decrease the content of NH₄⁺ in rhizosphere soil. Significant correlations were observed between nitrogen contents or acid phosphatase and specific soil microbial communities.

Conclusions

These results underly that regardless of competition with native plants, the invasion of F. bidentis alters soil physicochemical properties and increases microorganism community diversity. This study establishes a theoretical foundation for further research on the invasion mechanisms of F. bidentis and provides valuable references for other studies about F. bidentis.

目的被称为 "生态杀手 "的入侵植物Flaveria bidentis (L.) Kuntze，由于其表型可塑性强、肥力高，对生态系统的稳定性构成了严重威胁。以往的研究表明，植物入侵与土壤微生物群落之间存在密切关系。本研究旨在更深入地了解双子叶榕入侵、土壤微生物群落多样性和土壤理化性质之间的关系。结果表明，无论是否存在本地植物物种，二叉金花的入侵都显著增加了根圈土壤中细菌和真菌的多样性。同时，双叉穗状花序菌增加了土壤中有机质和铵态氮（NH4+）的含量，降低了根圈土壤中 NH4+的含量。这些结果表明，无论是否与本地植物竞争，双叉蕨入侵都会改变土壤理化性质并增加微生物群落多样性。本研究为进一步研究二叉金线莲的入侵机制奠定了理论基础，并为其他有关二叉金线莲的研究提供了有价值的参考。

Purpose

Viruses are the largest genetic repository and most diverse host-associated replicating organisms in a wide range of ecosystems in the entire biosphere. Although playing crucial roles in numerous processes such as nutrient cycles, viral shunt, and population control within marine ecosystems, viral communities continue to be the least explored biological entities, particularly in extreme marine habitats. Therefore, details about the viral diversity and their metabolic potential from Arctic sediments has great importance.

Methods

Sediment samples were collected from two Arctic fjords, Kongsfjorden and Krossfjorden, in Svalbard. Viral nucleic acids were extracted from both fjord sediments after a pre-processing step. Illumina Novaseq based shotgun sequencing was performed and bioinformatic analysis was done to explore viral communities and their functional potential.

Results

An array of DNA and RNA viruses especially bacteriophages along with viruses infecting algae, plants, molluscs, shrimps, fishes, amphibians, reptiles, birds, humans, and other mammals were detected from both fjords. The double-stranded DNA viruses were the most abundant (Siphoviridae, Podoviridae, Myoviridae, and Phycodnaviridae), followed by single-stranded DNA (Inoviridae) and RNA (Retroviridae and Betaflexiviridae) viruses from both metavirome. Functional analysis explored genes encoding virus structures, enzymes for phage replication, integration and excision and proteins related to phage regulation of gene expression.

Conclusions

Fjord metavirome analysis revealed the occurrence of virus groups endemic to Arctic freshwater and marine habitats along with an extra pool of unclassified or unassigned virus reads. Viruses infecting a variety of bacterial groups, and other higher trophic levels in fjord environments were explored. Functional annotation revealed the abundance of phage-related structural genes and metabolic genes. Comparative analysis revealed the abundance of dsDNA viruses from Caudovirales (Myoviridae, Podoviridae and Siphoviridae) in all the analysed Arctic samples in different proportions. The present study enhances our understanding of viral diversity and their metabolic potential in Arctic fjord sediments.

目的病毒是整个生物圈广泛生态系统中最大的基因库和最多样化的宿主相关复制生物。虽然病毒群落在海洋生态系统的营养循环、病毒分流和种群控制等众多过程中发挥着至关重要的作用，但它仍然是探索最少的生物实体，尤其是在极端的海洋生境中。因此，详细了解北极沉积物中的病毒多样性及其新陈代谢潜力具有重要意义。经过预处理步骤后，从这两个峡湾的沉积物中提取了病毒核酸。结果在两个峡湾中都检测到了一系列 DNA 和 RNA 病毒，尤其是噬菌体病毒，以及感染藻类、植物、软体动物、虾、鱼类、两栖动物、爬行动物、鸟类、人类和其他哺乳动物的病毒。双链 DNA 病毒数量最多（Siphoviridae、Podoviridae、Myoviridae 和 Phycodnaviridae），其次是单链 DNA 病毒（Inoviridae）和 RNA 病毒（Retroviridae 和 Betaflexiviridae）。功能分析探讨了编码病毒结构的基因、噬菌体复制、整合和切除的酶以及与噬菌体调控基因表达有关的蛋白质。研究还探讨了峡湾环境中感染各种细菌群和其他较高营养级的病毒。功能注释显示了噬菌体相关结构基因和代谢基因的丰富程度。比较分析表明，在所有分析的北极样本中，dsDNA 病毒（Caudovirales）（Myoviridae、Podoviridae 和 Siphoviridae）的数量和比例各不相同。本研究加深了我们对北极峡湾沉积物中病毒多样性及其代谢潜力的了解。
