Climate and Land-Use Changes Predicted to Jointly Drive Soil Fungal Diversity Losses in One-Third of North American Coniferous Forests. [PDF]
Glob Chang BiolThis study assessed the potential impacts of climate and land‐use change on soil fungal diversity across four North American biomes. We found that climate change typically caused both diversity losses and gains, particularly in coniferous forests and among arbuscular mycorrhizal fungi, whereas land‐use change mainly reduced diversity, especially in ...

Mechanistic approaches to investigate soil microbe‐mediated plant competition
Journal of Ecology, Volume 111, Issue 8, Page 1590-1597, August 2023., 2023 Our review highlights recent experimental advancements for uncovering microbial mechanisms that alter plant host resource competition and coexistence. We synthesize these mechanisms into a conceptual model that provides a framework for future experiments to investigate the importance of plant–microbe interactions in structuring plant populations and ...

Effects of Biochar Application on Nitrogen and Phosphorus Availability in Soils: aReview [PDF]
, 2016 利用生物炭在贫瘠的土壤上培育出肥沃的"黑土"正成为土壤学家研究的热点.氮、磷等大量养分是衡量土壤肥力高低的重要指标,生物炭对其有效性影响表现出极大的复杂性.不同研究得出的结论不尽相同,关键是缺乏对其机制的深入研究.由于氮和磷的不合理利用还可能造成非点源污染而带来环境风险,再加之生物炭施用的不可逆性,必须确保生物炭在任何情况下都不会对土壤和环境带来不利的影响.为此,本文综述了生物炭添加对氮肥和磷肥在土壤-植物系统迁移转化过程中的作用,重点讨论了不同生物炭处理方式对土壤磷素吸附解吸和形态转化的影响 ...

The Role of Microorganisms in the Geochemical Iron Cycle [PDF]
, 2016 铁元素虽然只在地壳含量中位列第4,但却是地球上分布最广的变价金属元素之一,微生物介导的铁循环及其与生源要素碳、氮、氧和硫等耦合的氧化还原反应是微生物地球化学循环的重要驱动力.由于铁循环过程中氧化态三价铁Fe(Ⅲ)在环境p H条件下大多以不溶状态存在,因而由其参与的地球化学循环进程通常较为缓慢.研究表明,微生物在铁元素的地球化学循环过程中起着举足轻重的作用,并在该过程中参与矿物的生成与转化.近年来的最新研究发现,参与地球化学铁循环的微生物之间,微生物与矿物之间,以及矿物介导的微生物之间存在着多样的相互作用,

紫茎泽兰入侵下喀斯特退化天坑的土壤微生物群落特征 [PDF]
, 2019 紫茎泽兰入侵到宏大地表负地形的喀斯特退化天坑后,会通过改变其立地环境的土壤微生物群落来影响退化天坑的植物多样性、群落演替与自然生态恢复.以云南沾益天坑群的典型退化天坑巴家陷塘为研究区,选择不同生境的紫茎泽兰根系土壤,采用Biolog微平板法探究紫茎泽兰根系土壤微生物群落特征.结果表明:受退化天坑内生境异质性影响,紫茎泽兰的入侵程度表现为坑坡灌草地>坑底草地>坑坡林地>坑口灌草地,并且不同生境的紫茎泽兰性状特征存在差异;紫茎泽兰根系土壤微生物代谢活性、优势度指数、丰富度指数 ...
