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

Shuitu Baochi Xuebao, 2008 2003—2004年开展对9个有代表性的不同产量的苹果园秋季土壤的养分、微生物类群及土壤酶活性的研究,获得不同产量苹果园的土壤微生物生态状况。结果表明,各苹果园的土壤养分、微生物数量、多样性和酶活性均表现出较大差异。随土壤碱解氮、速效磷、速效钾、总碳含量的增加,产量水平呈增高趋势。高产园土壤微生物数量高,多数土壤酶活性强,微生物多样性好。土壤微生物中细菌数量、微生物多样性、蛋白酶、磷酸酶活性可作为评价果园土壤肥力的生物指标。果树产量与土壤微生物类群和数量具有显著正相关,与速效磷、速效钾 ...

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 ...

Shuitu Baochi Xuebao, 2007 土壤微生物数量、土壤酶活性可以反映土壤的肥力状况。本文研究了东营泥质海岸不同林分下土壤养分、微生物数量、土壤酶活性及分布特征,结果表明：①土壤微生物、土壤酶和土壤养分主要分布在0-20 cm的土层,20-50 cm的较少;②不同林分微生物数量差异显著。白蜡林微生物数量最多,柳林、枣园数量较少,柽柳林数量最少。③不同林分土壤酶的活性表现出差异性,各种酶之间过氧化氢酶活性最高;④土壤养分含量差异显著,柳林土壤养分含量相对较高于其它样地,白蜡和桑园土壤养分含量次之 ...

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, 2011 以耐盐品种中棉所44为材料,模拟滨海混合盐土成分,研究了正常灌水(土壤相对含水量保持在75±5%)和轻度干旱(55±5%)下,不同程度盐胁迫(0,0.35%,0.60%,0.85%,1.00%)对棉田土壤微生物量和土壤养分的影响.结果表明,棉花产量及产量构成(铃数和铃重)、生物量、根重均随着盐浓度的升高而显著递减.棉田土壤微生物量C和N在棉花各个生育期内均随着盐浓度的升高而显著降低,花铃期达到最大,土壤有机质、全氮、速效N、有效P、速效K等养分含量的变化趋势与土壤微生物量C和N基本一致,但降幅较小 ...
