2022-03-21New progress on phylogenomic study of FagaceaYet to be sufficiently described across Fagaceae .Figure 1 Phylogenetic relationships and divergence time estimation of Fagaceae .Read More
Northern Hemisphere forests changed drastically since the early Eocene due to global climate change. Central to the floristic replacement with significant ecological consequence are the roughly 900 species currently recognized within Fagaceae (oak, beech, chestnut, stone oak). Fossils of modern Fagaceae are well represented in the Northern ... -
2022-02-25The development of a new technology to discriminate geographical origins of wolfberry (Lycium barbarum L.)To develop sophisticated approaches for distinguishing goji origins , 325 wolfberry fruit samples of a certain cultivar , plant age , drying method and collection season were gathered from 26 producing areas across Northwest China in 2017 and.The indices selected in this study can distinguish gojis produced in Zhongning County from fruit origina...Read More
To develop sophisticated approaches for distinguishing goji origins, 325 wolfberry fruit samples of a certain cultivar, plant age, drying method and collection season were gathered from 26 producing areas across Northwest China in 2017 and 2018. We employed 49 indices, including stable isotopes, earth elements, soluble amino acids, and sacc... -
2022-01-22Joint approaches to reduce cadmium exposure risk from rice consumptionHeavy metals in situ .Rice is a crop that can easily accumulate cadmium ( Cd ) . With the rapid development of economy, heavy metal pollution of farmland soil and crops caused by various natural and human factors is becoming more and more serious. In situ passivation remediation technology is a highly respected treatment method at present. It can reduce the absorption of heavy metals by crops by applying soil passivator to s...Read More -
2021-12-20New research progress on conservation of rare tree fern Sphaeropteris lepiferaSphaeropteris lepifera , a tree fern belonging to the family Cyatheaceae , is valued medicinally and horticulturally .Tried to reintroduce artificially bred fiddleheads near the native environment such as Nan ' ao County of Shantou City in Guangdong Province . Based on the suitability distribution results of maximum entropy ( MaxEnt ) model and ... Sphaeropteris lepifera, a tree fern belonging to the family Cyatheaceae, is valued medicinally and horticulturally. Despite its present conservation status, this fern represents an ancient lineage that originated ca. 300 million years ago, became relatively widespread, and, later, underwent extinctions leading to its present restricted distribut...Read More -
2021-12-17Effects of nitrogen addition and increased precipitation on xylem growth of Quercus acutissima Caruth. in central ChinaWeekly intervals during 2014 –.Interactive effect of nitrogen addition ( N0 and N1 ) , precipitation increase ( P0 and P1 ) , and season ( S1 , S2 , and S3 ) on relative xylem growth in 2015 made using the “ pairs ”.Function in R package “ lsmeans ” . Atmospheric nitrogen (N) deposition and increasing precipitation affect carbon sequestration in terrestrial ecosystems, but how these two concurrent global change variables affect xylem growth in trees (i.e. independently or interactively) remains unclear. South China Botanical Garden conducted novel experiments in central China to monitor the x...Read More -

2021-11-25High retention of 15N-labeled nitrogen in a N-rich legume forestEcosystems because of symbiotic biological N-fixation . However , until now , considerable progress on the role of legumes in the N cycle has mainly focused.Labeling experiment in a legume plantation forest ( Acacia auriculiformis ) and a nearby non-legume forest ( Eucalyptus urophylla ) , which has been.Legume forest than the non-legume forest ...Read More
Human activities have increased atmospheric nitrogen (N) deposition and affected the structure and function of forest ecosystems. The effects of increased N deposition on forests greatly depend on the fates of the deposited N. Legume trees are widely distributed across terrestrial forests, especially in the tropics. They play a key role in ... -
2021-11-16Nitrogen deposition does not always induce soil acidification in tropical forestsAnthropogenic nitrogen ( N ) deposition rates have rapidly increased at the global scale , which has become an environmental issue that receives wide-spread concerns .The results showed that long-term N addition did not affect soil acidity in the two plantations , with no significant changes in soil pH values and exchangeable non-acidic and acid... Anthropogenic nitrogen (N) deposition rates have rapidly increased at the global scale, which has become an environmental issue that receives wide-spread concerns. It is well documented that elevated N deposition often exacerbates soil acidification in tropical/subtropical forests, characterized by the decreases in soil pH values and acidic cati...Read More
