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

2020-06-01Variations of leaf eco-physiological traits in relation to environmental factors during forest successionAuthor: HAN Taotao E-mail: hantt@scbg.ac.cn Paper link: https://doi.org/10.1016/j.ecolind.2020.106511 Online time: 27 May 2020 Changes in leaf physiological traits and shifts in their relationships are expected to reveal plant ecological strategies during succession, and how they interact with the changing environment are thought to be useful in forest restoration and management. Although the relationships between leaf physiological traits and other structural and chemi...Read More

2020-05-22Soil organic carbon turnover following forest restoration in south China: Evidence from stable carbon isotopesAuthor: XIONG Xin E-mail: xiongx@scib.ac.cn Paper link: https://doi.org/10.1016/j.foreco.2020.117988 Online time: 21 February 2020 As over half of the world’s tropical forests are reforested or afforested, understanding the resilience of carbon (C) pool in these forests is critical for global C balance. Studies regarding the influence of afforestation on soil C stocks have been conducted extensively in recent years. However, how forest restoration affects soil C turnover i...Read More

2020-05-07Alternative pathway to trans-cinnamic acid from L-phenylalanine in plants was uncoveredAuthor: zenglanting@scbg.ac.cn E-mail: ZENG Lanting Paper link: https://pubs.acs.org/doi/10.1021/acs.jafc.9b07467 Online time: 20 February 2020 A recent research paper published in Journal of Agricultural and Food Chemistry describes an alternative pathway to the formation of trans-cinnamic acid (CA) derived from L-phenylalanine (L-Phe) in tea (Camellia sinensis) plants and other plants.Read More
The researchers from South China Botanical Garden of Chinese Academy of Sciences found that CA i... -
2020-05-06Shifts in fungal biomass and activities of hydrolase and oxidative enzymes explain different responses of litter decomposition to nitrogen additionAuthor: TAN Xiangping E-mail: tanxp@scbg.ac.cn Paper link: http://link.springer.com/10.1007/s00374-020-01434-3 Online time: 25 January 2020 Exogenous nitrogen (N) input is a key factor affecting litter decomposition. Yet our mechanistic understanding of microbial community and EE response to N addition and their associated effect on litter decomposition is still limited.Read More
In a research article recently published in the journal Biology and Fertility of Soils, researchers from Sout... -
2020-04-30Autumn phenology controls the temporal change in growing season length of herbaceous plants on the Qinghai–Tibetan PlateauAuthor: SUN Qingling E-mail: sunqingling@scbg.ac.cn Paper link: https://doi.org/10.1016/j.agrformet.2019.107896 Online time: 7 January 2020 Plant phenology is a sensitive bio-indicator of climate and natural environment change. Shift in plant phenology and its response to climate change on the Qinghai–Tibetan Plateau (QTP) have been a hot research topic during the recent decade. On the QTP, previous phenological studies have shown an overall lengthening trend of the growing season ...Read More
