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 ...

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,

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

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 ...

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.

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 ...

Shuitu Baochi Xuebao, 2011 以太湖流域典型蔬菜地为研究对象,采用田间径流池法进行田间小区试验,研究不同施肥模式下蔬菜地地表径流氮磷流失特征。结果表明:地表径流总氮流失量为45.76～60.45 kg/hm2,总磷流失量为2.67～3.95 kg/hm2。与常规施肥相比,优化施肥可使地表径流氮磷流失量分别减少2.48,0.31 kg/hm2;而增氮施肥和增磷施肥处理的地表径流总氮流失量分别增加了7.76%,3.83%,总磷流失量增加2.84%,9.55%。总氮、总磷流失量与径流量呈显著线性相关,且总磷流失量与径流量的相关性更强(R2=
