Tree species richness differentially affects the chemical composition of leaves, roots and root exudates in four subtropical tree species

open access: yesJournal of Ecology, Volume 110, Issue 1, Page 97-116, January 2022., 2022
In the BEF‐China experiment, metabolomics samples were collected from four different species and three organs (a). The metabolomes are species and organ specific (b), and the metabolome specificity is attributed to different chemical classes (c). Tree species diversity affects the metabolome composition (d), but more controlled interaction experiments ...

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

open access: yesFunctional 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 ...

Ecological Restoration of Rubber Monocultures: Strategies for Biodiversity and Ecosystem Recovery in Tropical Regions 题目:如何将橡胶林恢复为多样森林?

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 345-353, September 2025.
Restoration of monoculture in protected and marginal areas can be organized into two phases (1) identification and prioritization of restoration sites based on remote sensing or field survey then assessing degradation level, and (2) implementation of appropriate restoration interventions.

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

open access: yesNew 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

Geochemistry of surface sediments from the continental shelf of the East China Sea and small rivers of SE China: Constraints on chemical weathering and provenance [PDF]

open access: yes, 2015
沉积物元素地球化学特征可为沉积环境演化历史提供重要信息,包括沉积物物源、物源成分特征、物源区岩石风化侵蚀程度、成岩作用、沉积物传输、沉积过程及古气候变化等。本研究于东海大陆架,瓯江、闽江和晋江河口共采集79个表层沉积物样品,分析其常微量元素地球化学特征并探讨物源区性质及化学风化特征。UCC和UC-YC标准化蛛网图表明,CaO、Na2O、Ba和Sr呈现出不同程度的亏损,而Rb元素则轻微富集。硅酸盐风化指数(CIA、PIA和CIW)及三角形图(A-CN-K、(A-K)-C-N和A-CNK-FM ...

Comparative efficacy of selenoureido carbonic anhydrase inhibitors and azole antifungal drugs against clinical isolates of Malassezia pachydermatis

open access: yesVeterinary Dermatology, Volume 36, Issue 3, Page 302-313, June 2025.
Background – Malassezia pachydermatis (MP) is implicated in severe dermatitis and otitis externa (OE) of companion animals and recently gained attention for its increasing resistance to azole compounds. For this reason, developing novel therapeutic strategies is of great interest. In a previous work, we used reference yeast isolates to evaluate several

不同植被恢复对侵蚀型红壤活性碳库的影响

open access: yesShuitu Baochi Xuebao, 2004
为了解侵蚀型红壤不同植被恢复后,土壤有机碳的演变状况,采集了持续时间为17年和9年的2个定位试验点土壤样品,分析了土壤总有机碳、微生物量碳、水溶性碳和矿化态碳含量.结果表明侵蚀型红壤植被恢复后,土壤总有机碳和各类活性碳含量均明显增加,并随着恢复时间的延长,土壤各类碳含量显著上升.同样是杉木林,恢复17年的土壤(0~20 cm)总有机碳、微生物量碳、水溶性碳和矿化态碳的含量分别是恢复9年土壤的2.18倍、2.95倍、2.25倍和2.01倍.不同处理比较来看,木荷林土壤各类碳含量明显高于杉木林土壤 ...

Spatial and temporal distribution of nitrite-dependent anaerobic ammonium and methane oxidation bacteria in mangrove wetland [PDF]

open access: yes, 2017
厌氧氨氧化(anaerobicammoniumoxidation,ANAMMOX)和反硝化型厌氧甲烷氧化(nitrite-dependentanaerobicmethaneoxidation,N-DAMO)反应是新发现的两类能够参与碳氮循环的微生物,它们的发现对完善全球碳氮循环理论具有重要意义。红树林湿地生态系统位于陆地和海洋交界处,周期性受海水浸淹,并且能够接受来自海洋和陆地的各种污染物,因此物质资源和生物资源都很丰富。同时,红树林湿地沉积物能够为ANAMMOX和N-DAMO微生物创造一个厌氧环境 ...

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

open access: yesFunctional 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 ...
