The Accommodation of Nitrogen to Polycyclic Aromatic Hydrocarbons (PAHs) Pollution in Avicennia marina [PDF]

, 2011
近年来，红树林湿地有机污染问题越来越突出，日益引起了人们的关注。根际是植物进行物质交换频繁的特殊微型生态区域，是有机物特别是持有性有机污染物进入红树植株内部的门户。根际微域复杂的微生物对植物的生长非常重要，并与有机污染物的吸收、转化和降解等生态化学行为及毒理效应密切相关。然而有关红树林湿地，营养元素对有机污染物毒害调节作用的研究鲜见报道，特别是对红树植物根际的微生物生态效应我们仍然所知甚少。 本研究通过自制根际套管，完全做到了根际研究器皿体积小，能避免施毒不匀、植物个体差异等实验干扰因素 ...

Factors influencing fine roots decomposition rates in response to nitrogen addition vary across root characteristics

Functional Ecology, Volume 39, Issue 12, Page 3504-3516, December 2025.
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 ...

模拟氮沉降对华北落叶松人工林土壤微生物碳和微生物氮的动态影响

Shuitu Baochi Xuebao, 2020
为揭示过量的大气氮沉降对华北落叶松人工林土壤微生物碳、氮和土壤呼吸的影响，通过对照（N0：0 g/（m2·a））、轻度施氮（N1：8 g/（m2·a））、重度施氮（N2：15 g/（m2·a））3个外源施氮水平下5年的野外定点试验和观测，模拟过量氮沉降条件下华北落叶松人工林土壤微生物碳、氮和土壤呼吸的变化，旨在阐明林下土壤微生物和呼吸对过量氮沉降的响应及其对土壤碳氮循环的影响。结果表明：在5—10月生长季中，土壤微生物碳和氮的平均含量分别为1 098.93，97.31 mg/kg ...

Effects of Cadmium on Soil Microbial Biomass and Enzyme Activities in Rhizosphere of the Kandelia candel Seedlings [PDF]

, 2009
近年来，红树林湿地重金属污染问题越来越突出，日益引起了人们的关注。根际是物质交换频繁的特殊微型生态区域，是重金属进入红树植株内部的必经之路。根际微域复杂的微生物对植物的生长非常重要，并与重金属的吸收、转化和迁移等生态化学行为及毒理效应密切相关。然而有关红树林根际微生物对重金属胁迫的响应的研究鲜见报道，重金属污染对红树植物根际的微生物生态效应我们仍然所知甚少。本研究通过根箱盆栽红树植物秋茄（Kandeliacandel(L.)Druce）幼苗，分离根际与全土区域 ...

Altered nutrient cycling functionality in seagrass meadows under a simulated future marine heatwave event

New Phytologist, Volume 247, Issue 6, Page 2616-2629, September 2025.
Summary Seagrasses are important contributors to environmental nutrient cycling in marine ecosystems and can improve water quality by absorbing excess nitrogen (N). However, these ecosystems are vulnerable to human‐mediated pressures, including marine heatwaves (MHWs), particularly those of longer duration. We performed an experiment simulating a 30‐d,

Arbuscular mycorrhizal fungus reshapes the rhizosphere microbiome of alfalfa in response to above‐ground attack by aphids and a fungal plant pathogen

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

Tree mycorrhizal associations regulate relationships between plant and microbial communities and soil organic carbon stocks at local scales in a temperate forest

Functional Ecology, Volume 39, Issue 6, Page 1550-1566, June 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Forests store substantial amounts of soil organic carbon (SOC), but SOC stocks differ strongly between forest ecosystems dominated by arbuscular mycorrhizal (AM) or ectomycorrhizal (EcM) fungi.

Plant–microbe interactions drive the rhizosphere microbial assembly and nitrogen cycling in a subtropical forest

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 ...
