Factors that shape large‐scale gradients in clonality
Journal of Biogeography, Volume 50, Issue 5, Page 827-837, May 2023., 2023 Abstract Aim Many plant species reproduce clonally. However, ecologists still have much to learn about the factors that shape large‐scale patterns in plant clonal growth and reproduction, especially in the southern hemisphere. We addressed this knowledge gap by quantifying relationships between reproductive mode and a suite of plant characteristics and

Are ecophysiological adaptive traits decoupled from leaf economics traits in wetlands?
Functional Ecology, Volume 33, Issue 7, Page 1202-1210, July 2019., 2019 Plain Language Summary Abstract Wetland plants have developed a suite of traits, such as aerenchyma, radial oxygen loss and leaf gas films, to adapt to the wetland environment characterised by, for example, a low redox potential and a lack of electron acceptors.

Rare Metals, EarlyView.ABSTRACT Recently, cobalt/nitrogen co‐doped materials have emerged as heterogeneous catalysts to activate peroxymonosulfate (PMS) and have been applied to advanced oxidation processes for environmental remediation. However, their recyclability and reusability remain major barriers to practical application.

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 ...

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 ...

长期氮沉降和地上凋落物处理对半干旱区沙质草地表层土壤碳氮组分的影响
Shuitu Baochi Xuebao, 2023 为揭示半干旱区沙质草地生态系统中表层土壤C、N组分对长期氮添加和地上凋落物处理的响应特征,以科尔沁沙地西南部国家野外科学观测研究站建立的长期(9年)氮添加和凋落物处理样地为平台,测定并分析该样地表层土壤环境因子、铵态氮、硝态氮、总有机碳、不同碳氮组分。结果表明:(1)持续9年的氮添加和地上凋落物处理对表层土壤环境因子和不同碳氮组分无交互作用;(2)氮添加处理显著降低土壤pH ...

Shuitu Baochi Xuebao, 2007 大气氮沉降对受氮限制的陆地生态系统碳截存/损耗的机理尚不清楚,尤其是对土壤有机碳(SOC)的输入、转化和输出过程的认识明显不足。本文论述了外源性氮素(氮沉降、人为增氮)对凋落物分解、土壤有机碳各组分周转的影响,以及土壤呼吸各组分(根系自养呼吸、根际微生物呼吸和SOM分解)对增氮的响应等领域的最新研究进展,指出了在上述研究领域中存在的问题,并提出拟解决的途径以及未来的可能研究方向,以期为该领域的研究提供参考。

Shuitu Baochi Xuebao, 2021 采用田间试验探究了不同施肥处理对稻田氮素流失的影响，其中不同施肥包括对照（CK）、常规施肥（CT）、有机肥替代（BS）和炭基肥（CB）4个处理。结果表明：CB和BS组对降低稻田氮素径流流失的效果显著（p < 0.05），其中稻田铵态氮的径流流失总量CT组（20.08 kg/hm2） > BS组（15.53 kg/hm2） > CB组（12.68 kg/hm2） > CK组（0.63 kg/hm2）。通过估算不同深度土壤的铵态氮与硝态氮淋溶流失量可知，BS和CB组对降低稻田氮素淋溶流失的效果有限。CT ...
