2019-07-17Global Pattern and Controls of Biological Nitrogen Fixation under Nutrient EnrichmentAuthor: ZHENG Mianhai E-mail: zhengmianhai@scbg.ac.cn Paper link: https://doi.org/10.1111/gcb.14705 Biological nitrogen (N) fixation (BNF), an important source of N in terrestrial ecosystems, plays a critical role in terrestrial nutrient cycling and net primary productivity. Currently, large uncertainty exists regarding how nutrient availability regulates terrestrial BNF and the drivers responsible for this process.Read More

2019-07-08Researchers Reveal Contributions of Competition and Climate on Radial Growth of Pinus Massoniana in Subtropics of ChinaAuthor: LIANG Hanxue E-mail: hanxuel@scbg.ac.cn Paper link: https://doi.org/10.1016/j.agrformet.2019.04.014 The limiting factor of tree growth in subtropical regions of China has not been conclusive. Numerous studies have shown that climate is not the primarily limit factor of tree growth. Therefore, it is widely speculated that competition may play a vital role, but there is no relevant report at present, and there is no more quantifying the effect.Read More

2019-07-02Distinct Responses of Soil Fungal and Bacterial Nitrate Immobilization to Land Conversion from Forest to AgricultureAuthor: LI Xiaobo E-mail: lixiaobo@scbg.ac.cn Paper link: https://www.sciencedirect.com/science/article/pii/S0038071719300847 Forest conversion to agriculture has recently been found to result in a substantial decrease in microbial nitrate (NO3-) assimilation in soil, which is a key cause of NO3- accumulation and thus increases the risk of nitrogen losses from agricultural soils.Read More
However, how and why the respective NO3- assimilation of fungi and bacteria, the domin... -
2019-06-18Leaf Mechanical Strength Varies Independently with Photosynthetic CapacityOne research paper published in New Phytologist describes the independent relationship between leaf mechanical strength and photosynthetic capacity across 57 woody species with contrasting light requirements in Dinghushan Biosphere Reserve. Author: HE Pengcheng E-mail: hepengcheng@scbg.ac.cn Paper link: https://nph.onlinelibrary.wiley.com/doi/1... One research paper published in New Phytologist describes the independent relationship between leaf mechanical strength and photosynthetic capacity across 57 woody species with contrasting light requirements in Dinghushan Biosphere Reserve.Read More
Forest species can be clarified as either ‘light demanding’ or ‘shade tolerant’ according to their... -
2019-06-06Soil Moisture Drives Microbial Controls on Carbon Decomposition in SubtropicsAuthor:Huang Wenjuan E-mail:wjhuang@scib.ac.cn Paper link:https://www.sciencedirect.com/science/article/abs/pii/S0038071718304279 Researchers provide strong evidence of microbial control over soil carbon (C) decomposition and suggest the future trajectory of soil C may be more responsive to changes in soil moisture than temperature in subtropics. Researchers from Dinghushan Forest Ecosystem Research Station of South China Botanical Garden, Chinese Academy of Sciences (SCBG) provide strong evidence of microbial control over soil carbon (C) decomposition and suggest the future trajectory of soil C may be more responsive to changes in soil moisture than temperature in subtropics.Read More

2019-05-22Interactive effects of nitrogen and phosphorus additions on plant growthJIANG Jun performed a meta-analysis of 133 independent studies conducted in four natural terrestrial ecosystems to examine the interactive effects of N and P additions on ten plant growth-related variables. Author: JIANG Jun E-mail: jiangjun@scbg.ac.cn Paper link: https://doi.org/10.1007/s11104-019-04119-5 Plant growth in terrestrial ecosystems is commonly limited by nitrogen (N) or phosphorus (P). At high latitudes, temperature is low, soil N mineralization is also low, and plant growth is often limited by available N. In tropical forests on old soils, available soil P is low, and plant growth is often limited by P. In recent years, co-limitation...Read More

2019-05-22Nitrogen-phosphorous interactions can promote plant uptake of both nutrientsChinese researchers have disclosed that the nitrogen and phosphorous interactions can promote uptake of both nutrients by plants. （Xinhua） Chinese researchers have disclosed that the nitrogen and phosphorous interactions can promote uptake of both nutrients by plants.Read More
Nitrogen and phosphorus are two of the essential nutrient elements for plant growth. But how the interactions of the two elements differ among different terrestrial ecosystems remains unclear, according to the res... -
2019-05-16Precipitation or Phylogeny: Which Drives the Variation of Plant Hydraulics of Subtropical Trees?Author: LIANG Xingyun E-mail: liangxingyun@scbg.ac.cn Paper link: https://authors.elsevier.com/a/1YgZzcFXJSYMP In a recent article in Agricultural and Forest Meteorology, a research group led by Professor YE Qing of South China Botanical Garden (SCBG) of Chinese Academy of Sciences (CAS), has made advances in understanding the drivers of the va... Plant hydraulic traits represent strategies of water transport efficiency and safety, affecting the growth, survival and distribution of trees under different environmental conditions.Read More
Although both can contribute to the variation of plant hydraulic traits, the effects of environment and phylogeny have not been clearly distinguished.
