2011-01-17How Nitrogen Deposition Affects Tropical Forest Plant DiversityIn 2010,Dr. ,Global Change Biology,2010,16:2688–2700).On the base of this finding,their further study in Dinghushan Biosphere Reserve for six years showed that responses of plant diversity in reforested forests varied with different land-use history. It also has great significance for valuing changes of forest biodiversity under the background ... In 2010, Dr. LU Xiankai, Prof. MO Jiangming and his colleagues from SCBG found that elevated N deposition may decrease plant diversity of “N-rich” forests (see Lu et al., Global Change Biology, 2010, 16: 2688–2700). On the base of this finding, their further study in Dinghushan Biosphere Reserve for six years showed that responses of plant di...Read More -
2010-12-24Gibberellins (GAs) modulate jasmonate (JA) signalingGibberellins(GAs)modulate jasmonate(JA)signaling,which is essential for stress response and development of plants. A great progress achieved on this field recently. Because DELLAs serve as central regulators that mediate the crosstalk of various phytohormones,our mode lalso suggests a candidate mechanism by which JA signaling may be fine-tuned b... Gibberellins (GAs) modulate jasmonate (JA) signaling, which is essential for stress response and development of plants. However, the molecular details of such phytohormone interaction remain largely unknown.Read More

2010-12-10South China Institute of Botany Gets Grant of Key Program from Natural Science Foundation of China on Forest TranspirationHow forests regulate transpiration in order to adapt to the new distribution pattern of water and to maintain effective water use is a pressing issue needing to be addressed. The new project hypothesizes that hydraulic conductance and canopy stomatal conductance of trees jointly control the response of forest water use to evaporative demand in c... With previous projects funded by Natural Science Foundation of China (NSFC), Chinese Academy Science Knowledge Innovative Program and Natural Science Foundation of Guangdong Province, the Research Group of Ecosystem Physiology, headed by Prof. ZHAO Ping, has conducted research on plantation water use and H2O/CO2 exchange fluxes between forest ca...Read More

2010-11-28The Ecological Economic Study of Rice Production System in Pearl River DeltaChina is the largest rice producing and consuming country in the world,but rice production has given way to the production of vegetables during the past twenty years. An economic analysis clearly showed that the reason for this conversion was simply that the economic output/input ratio and the benefit density of the vegetable production system w... China is the largest rice producing and consuming country in the world, but rice production has given way to the production of vegetables during the past twenty years. The government has been trying to stop this land-use conversion and increase the area in rice-vegetable rotation. ''What is the reason behind this conversion?''; ''Which system is...Read More

2010-11-23New Advance on Ecological Economic Research of Aquaculture Systems on Wetlands Surrounding the Pearl River Estuary, ChinaPearl River is one of the produce and export area for aquacultural products,and the rapid development of aquaculture is also one of the main results for the past shrinkage of mangrove ecosystem and the difficult restoration of it. Counter intuitively,the high economic input and output mode did not have higher environmental impact or lower sustai... Pearl River is one of the produce and export area for aquacultural products, and the rapid development of aquaculture is also one of the main results for the past shrinkage of mangrove ecosystem and the difficult restoration of it. Thus, the ecological economic benefit and impact of these aquaculture systems have great effect on regional sustai...Read More
