Plant functional trait dissimilarity drives plant mixture effects on fine root biomass and trait variations

New Phytologist, Volume 249, Issue 2, Page 764-776, January 2026.
Summary Fine roots are critical for soil resource uptake, yet how declining plant diversity alters fine root biomass (RB) and traits remains unclear. We tested how plant functional trait dissimilarity in shade tolerance, drought tolerance, growth rate, and nitrogen‐fixation ability drives variation in root attributes.

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 ...

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,

Wild Cicer species exhibit superior leaf photosynthetic phosphorus‐ and water‐use efficiencies compared with cultivated chickpea under low‐phosphorus conditions

New Phytologist, Volume 247, Issue 1, Page 144-159, July 2025.
Summary Domesticated chickpea cultivars exhibit limited genetic diversity. This study evaluated the effects of chickpea domestication on phosphorus (P)‐use efficiency (PUE) under low‐P conditions, using a diverse Cicer collection, including wild species. Two wild Cicer species – 54 C. reticulatum accessions and 15 C. echinospermum accessions, and seven

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 ...

青海湖环湖区表土有机碳氮储量估算

, 2011
分析了沿青海湖湖岸采集的81个表土样品的总有机碳和氮含量得出:环湖区表土有机碳储量为27.81×106t,总氮储量为30.24×105t。占研究区面积最大的栗钙土,其表层土壤有机碳密度(8.19kg/m2)显著高于同类研究,氮含量(3.63mg/g)亦高于青海省同类土壤的平均值,说明环湖区表土碳氮储量都是相当大的。同时 ...

Guanotrophy: Waterbirds Pay for Using Resources at Their Wintering Habitats 鸟粪营养学 ：水鸟在越冬栖息地使用资源后留下回报

Integrative Conservation, Volume 3, Issue 4, Page 382-397, December 2024.
Significant waterbird colonisation was recorded in the wintering period (October through March in 2018–2019 and 2019–2020) in wetlands on Central Asian and East Australasian Flyways. Different limnochemical conditions influenced nitrate and phosphate concentrations.

Trade‐off between soil carbon sequestration and net ecosystem economic benefits for paddy fields under long‐term application of biochar

GCB Bioenergy, Volume 16, Issue 1, January 2024.
The use of biochar increased greenhouse gas (GHG) emissions but countered the harm caused by GHG emissions by considerable soil carbon sequestration resulting in a negative carbon footprint. Furthermore, the use of biochar lowered the proportion of CH4 and N2O, demonstrating that biochar usage has a considerable positive effect on GHG emissions ...

富营养化治理应放宽控氮、集中控磷

, 2009
传统上普遍认为,湖泊富营养化及蓝藻水华治理需要严格控制氮的排放.国际上最新研究否定了这一观点.文中首先通过分析指出传统控氮观念的科学基础并不可靠,其中氮磷比假说只是一种臆断,而封闭瓶营养添加实验未能模拟自然固氮过程.然后介绍在长江流域40多个湖泊多年比较研究的最新成果:无论总氮浓度是高还是低,总磷浓度都是限制浮游藻类生长的最重要因素,藻类总量决定于总磷而不是总氮,从而证明在野外条件下控氮不能减少藻类总量.研究结果得到北美长期全湖实验的证实.这两个研究点面结合,共同阐明了"减氮不能控制藻类总量 ...
