2020-07-29The effects of invasive plants on the health of forest ecosystems on small tropical coral islands were complex and desynchronizedAuthor: CAI Hongyue E-mail: hongyuecai@scbg.ac.cn Paper link: https://doi.org/10.1016/j.ecolind.2020.106656 Online time: 1 July 2020 Plant invasion is a major factor leading to the degradation of indigenous vegetation on tropical coral islands, where ecosystems are fragile and endemism tends to be high. The holistic effects of biological invasions on island forests and their belowground organisms are poorly understood.Read More

2020-07-23Nitrogen deposition differentially changes the carbon metabolisms of dominant woody species in an evergreen broad-leaved forestAuthor: LIU Nan E-mail: liunan@scbg.ac.cn Paper link: https://doi.org/10.1016/j.scitotenv.2020.138738 Online time: 17 April 2020 Human activities have significantly increased atmospheric nitrogen emissions and nitrogen deposition, such that atmospheric nitrogen deposition has become a major focus of environmental science and policy. Because nitrogen deposition is a global problem, the effects of nitrogen deposition on forest plants have been widely studied. The effects of...Read More

2020-07-22Vegetation has different sustainable potential regeneration in different areas on tropical coral islandAuthor: HUANG Yao E-mail: huangyao.ok@scbg.ac.cn Paper link: https://doi.org/10.1016/j.ecolind.2020.106689 Online time: 9 July 2020 Vegetation is integral to coral reef as it facilitates accretion and stabilization, previous research proposed that vegetation was affected by habitat heterogeneity across a narrow, but clear environmental gradient. However, the restoration potential of vegetation and relationship to habitat is unclear.Read More

2020-07-22Nitrogen deposition differentially affect the metabolism of Psychotria rubra, a dominant shrub species in an evergreen broad-leaved forestAuthor: LIU Nan E-mail: liunan@scbg.ac.cn Paper link: https://doi.org/10.1016/j.scitotenv.2020.138183 Online time: 25 March 2020 Since the Industrial Revolution, human activities have significantly increased atmospheric nitrogen emissions and nitrogen deposition back to the earth surface. With the rapid advancement of industrialization and urbanization, South China has experienced one of the highest rates of global nitrogen deposition. In addition to experiencing a very h...Read More

2020-07-14Plant residue amendment enhances nitrate immobilization by fungi and bacteria in soilAuthor: LI Xiaobo E-mail: lixiaobo@scbg.ac.cn Paper link: https://doi.org/10.1016/j.geoderma.2020.114450 Online time: 21 May 2020 Plant residue incorporation improves soil microbial nitrate immobilization, which in turn alleviates nitrate accumulation, thereby improving N retention capacity and reducing N losses. However, how and why the respective nitrate immobilization by fungi and bacteria, which are dominant microorganisms in soil, responds to residue addition remains ...Read More

2020-06-01Responses of the structure and health of plant and soil organism communities to canopy and understory nitrogen additions under a mature subtropical forestAuthor: TIAN Yang E-mail: tianyang16@scbg.ac.cn Paper link: https://doi.org/10.1016/j.scitotenv.2020.137438 and https://doi.org/10.1016/j.ecolind.2019.105459 Online time: 20 February 2020 The increase in human activity has caused a severe increase in the emission of N to the atmosphere and the effects of N deposition have been especially severe in tropical and subtropical areas. Forest was served as the main acceptor of atmospheric N deposition, and its responses have received wide interest. The majority of experiments now add N ...Read More
