Functional Ecology, Volume 39, Issue 9, Page 2327-2341, September 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract While elevational patterns of soil bacterial and fungal communities in mountain ecosystems have been well documented, the assembly processes of soil archaeal and protistan communities, and their linkage with ecosystem multifunctionality (EMF), remain poorly understood ...

Functional Ecology, Volume 39, Issue 8, Page 2149-2169, August 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants assemble beneficial rhizosphere microbiomes through a ‘cry for help’ mechanism upon pathogen or insect herbivore attack. The arbuscular mycorrhizal fungi (AMF) can influence the composition of microbial communities in the plant rhizosphere. However, their impacts

Journal of Ecology, Volume 113, Issue 7, Page 1746-1759, July 2025.In forests dominated by large clonal plants, such as giant moso bamboo, drought can alter the allocation of newly assimilated C within the tissues of source ramet but may not affect its allocation among interconnected ramets or within plant–soil systems.

Shuitu Baochi Xuebao, 1994 黄土高原地区土壤养分从黄土丘陵区、鄂尔多斯台地风沙区向内环辐射，由低增高；但是黄土高原地区氮磷缺乏，钾肥在一些地区和一些土壤上有显著增产效果，并能提高作物的品质。微量元素在一些土壤上也是缺乏的。今后在肥料上要进行二元或多元复合肥的施用。

Functional Ecology, Volume 39, Issue 4, Page 1096-1111, April 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Many invasive plant species have demonstrated a better ability to tolerate and accumulate heavy metals than their co‐occurring native plants. Given the potential biological toxicity of heavy metals to phytopathogens, we postulated that heavy metal contamination could ...

Shuitu Baochi Xuebao, 2019 为研究喀斯特高原峡谷石漠化治理区林草植被恢复对土壤团聚体的粒径分布，土壤结构稳定性及各粒径团聚体有机碳的影响，以期为喀斯特石漠化治理区土壤结构改善，植被重建，土壤碳库的维持与提高提供理论依据。以贵州喀斯特高原峡谷石漠化治理示范区5种常见林草植被（金银花、火龙果、花椒、荒草地和原生灌木林地）为研究对象，通过湿筛法对土壤团聚体粒径进行分组，对比分析5种林草植被模式下0-40 cm土层垂直剖面各土层土壤中团聚体和有机碳含量的分布规律。结果表明：在0-40 cm土层垂直剖面中，5种林草植被的土壤团聚体在>5，2~

Plant nutrient‐acquisition strategies contribute to species replacement during primary succession
Journal of Ecology, Volume 113, Issue 4, Page 988-1003, April 2025.Pioneer species Hippophae acquires phosphorus and nitrogen mainly by ‘mining’ and N2‐fixing strategies and thus dominates in the beginning of primary succession. As soil nutrient availability increases with the mobilization of apatite‐P and input of N‐rich plant residues, Hippophae' strategies become less efficient than Populus's scavenging strategies.

Shuitu Baochi Xuebao, 2006 采用田间采样及室内培养方法，对内蒙古武川县耕地、退耕还灌地和放牧草原3种类型土地土壤微生物各类群的数量分布和层化比率进行了研究。结果表明：在土壤耕作层（0～30cm）土壤微生物数量呈逐层下降趋势，3种类型土地的土壤微生物总数相差不大，3种类型土地土壤微生物层化比率存在明显差异。同时提出了土壤微生物层化比率的概念，并认为土壤微生物层化比率可能是一个比较好的指示动态土壤质量（土壤演替方向）的指标，当一个区域土壤微生物层化比率大于2时，土地一般不会发生退化现象。在研究的3块实验区域中，耕地存在较高的退化风险 ...
