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

Shuitu Baochi Xuebao, 2007 采集广州市中心城区部分公园绿地表层土壤（0-20 cm）,研究了土壤pH、有机质、粘粒、氮、磷、钾含量等肥力特性和脲酶、蔗糖酶、磷酸酶活性。结果表明,广州公园绿地土壤以酸性（pH 4.5-5.5）和中性（pH 6.5-7.5）占的比例高,部分土壤呈碱性,土壤pH值较自然土壤有增高的趋势;土壤有机质含量以中等水平为主,土壤全氮、碱解氮以中等到低水平为主。土壤全磷和有效磷以中等以上水平为主,土壤全钾、速效钾以中等以上水平为主,土壤脲酶、蔗糖酶和磷酸酶活性平均分别为0.36 m g NH3-N/g,12.29

Functional Ecology, Volume 39, Issue 5, Page 1274-1287, May 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Interactions between plants and soil microorganisms in the rhizosphere are vital for maintaining the nutrient cycle and stability of terrestrial ecosystems. Nitrogen, closely related to carbon (C) cycling and ecosystem productivity, undergoes transformation by soil ...

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.

Effects of Aegiceras corniculatum Mangrove Rehabilitation on Benthic Macro-fauna and Soil Properties at Jiulongjiang River Estuary and Some of Their Mechanisms [PDF]
, 2007 以福建九龙江口桐花树（Aegicerascorniculatum）林为研究对象，在龙海市角美镇的白礁海岸选取10yr生和5yr生人工桐花树林及天然成熟桐花树林，以光滩为对照，比较不同林龄桐花树林对大型底栖动物和土壤底质的影响；在龙海市浮宫镇的草埔头海岸选8yr生桐花树林和光滩与白礁红树林对照，比较潮位、盐度等因素的影响，为红树林植被恢复的生态系统改造提供科学指导和理论依据。研究结果表明，大型底栖动物物种的丰度及群落的物种多样性与红树林的发育状况具有相关性，且随盐度降低而减少。整体而言 ...

Functional Ecology, Volume 38, Issue 11, Page 2433-2446, November 2024.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phosphorus (P) acquisition strategy is considered to be an intrinsic driver behind plant succession. However, variations in plant P acquisition strategies in connection to soil P fraction changes after wetland drainage remain unclear.

, 2008 采用土培模拟方法研究了不同浓度Cd (0～50 mg/kg)对桐花树(Aegiceras corniculatum )土壤酶活性的影响. 试验 结果表明:低浓度Cd (0. 5 mg/kg)胁迫,可刺激脲酶的活性;在高浓度Cd (20～50 mg/kg)处理条件下,脲酶、蛋白酶、蔗糖 酶、过氧化物酶活性均受到不同程度的抑制,最大抑制率均达到25%以上; Cd处理对过氧化氢酶活性无显著影响.
