Climate and Land-Use Changes Predicted to Jointly Drive Soil Fungal Diversity Losses in One-Third of North American Coniferous Forests. [PDF]
This 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
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 ...

Rewilding in the face of climate change
Abstract Expansion of the global protected‐area network has been proposed as a strategy to address threats from accelerating climate change and species extinction. A key step in increasing the effectiveness of such expansion is understanding how novel threats to biodiversity from climate change alter concepts such as rewilding, which have underpinned ...

塔里木沙漠公路防护林土壤微生物生物量与土壤环境因子的关系 [PDF]
为探讨极端干旱区风沙土土壤微生物与土壤环境因子的作用规律,采用相关分析法研究了塔里木沙漠公路防护林地土壤微生物生物量与理化因子和酶活性的关系.结果表明:土壤容重和粒径减小(R0.85)时,防护林地中土壤微生物数量和生物量有增大趋势,由容重与微生物量的相关性主导;土壤养分含量与土壤微生物数量和生物量呈正相关,主要由速效养分和放线菌、微生物生物量C、P的相关性所致;土壤酶活性与土壤微生物数量和生物量的相关性差异较大,R在0.51~0.91,主要取决于蔗糖酶、磷酸酶与放线菌、微生物量C的相关 ...

土壤呼吸作用时空动态变化及其影响机制研究与展望. [PDF]
测定不同陆地生态系统土壤呼吸速率及其时空波动,阐明其影响因子,对于全球碳素平衡预算和全球变化潜在效应估计是最为基本的数据。然而,有关土壤呼吸作用变异性及其影响因素的知识仍存在局限性,一些关键的过程和机制还有待阐明。该文综述了近年来土壤呼吸作用时空动态规律、影响机制和模拟方面的研究进展,指出环境因子和生物因子共同驱动着土壤呼吸作用的时间动态变化;土壤呼吸作用在不同时间尺度上还具有明显的空间异质性,这主要是植被覆盖、根系分布、主要的环境因素和土壤特性空间分布的异质性造成的 ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract Nitrogen (N) deposition strongly affects litter decomposition and nutrient release, thereby reshaping carbon cycling in terrestrial ecosystems. Although most studies have focused on above‐ground litter, the effects of N addition on fine root decomposition and their ...
