Multiple Factors May have Forced Ephedra przewalskii Distribution Shrink in Ice Age: Study[Feb 15, 2017]

A recent study carried out on a desert shrub by scientists from the Chinese Academy of Sciences may provide some clues about the genetic variation pattern of species in the Quaternary ice age. Ephedra przewalskii is a drought-tolerant shrub with an extensive geographic range. It inhabits extremely dry semi-deserts, piedmont, and gravelly saline soil, and usually forms a large area within the plant community. It is usually taken as an indicator species in plant communities of the deserts in northwestern China.

Scientists Reveal Mast Seeding and Related Hypotheses in Temperate Deciduous Korean Pine Forest[Mar 16, 2017]

Dr. WANG Yunyun and other colleagues in the research group of Natural Forest Ecology, Institute of Applied Ecology (IAE) of the Chinese Academy of Scie analyzed seed rain data of 20 woody plant species collected from the big sample plot of 25 hectares Deciduous-Korean Pine Forest on Changbai Mountain in successive 8 years for variations and synchronism of seeding, then they tested the pollination hypothesis and the proximate effect of meteorological factors.

"Unusual" Behavior of Active Galactic Nuclei in Quiescence[Feb 28, 2017]

Active galactic nuclei (AGNs) and black hole X-ray binaries (BHBs) are the key directions in high-energy astrophysics. Recently, researchers at Shanghai Astronomical observatory (SHAO) of Chinese Academy of Sciences found that the quiescent AGNs follow a different radio/X-ray correlation (thus a different fundamental plane) from that of normal AGNs. They further proposed to investigate the fundamental plane under a revised parameter space.

Temperature Variations Affect Seasonal Variations in GPS Station Positions[Mar 16, 2017]

Dr. XU Xueqing's team at Shanghai Astronomical Observatory of Chinese Academy of Sciences calculated the displacements of GPS stations due to surface temperature variations based on a global thermoelastic model. They found that the seasonal GPS observations, the transverse displacements in particular, can be better explained after considering the thermoelastic effects caused by temperature variations.

Environmental Filtering Structures Functional Strategies of Plants in Xishuangbanna Tropical Rainforest[Mar 15, 2017]

Prof. CAO Min's team of Xishuangbanna Tropical Botanical Garden (XTBG) analyzed the relationships between traits and environmental gradients in phylogenetic and spatial contexts in the 20-ha Xishuangbanna Forest Dynamics Plot in Yunnan province, southwest China.

Manipulating the Evolution of Two-dimensional Liquid Foams Realizes A General Patterning Approach[Mar 15, 2017]

Based on the principle that micropatterned surface can effectively regulate the gas-liquid interface, Prof. SONG Yanlin from Institute of Chemistry of Chinese Academy of Sciences has focused on manipulating the evolution of 2D liquid foams with a mciropatterned surface. Researchers found that when foams evolve in the quasi-2D space consisted of a micropatterned surface and a flat glass cover-plate, the phenomenon of Ostawald ripening doesn't necessarily occur. The micropatterned surface can guide the evolution of 2D foams into equal sized bubble patterns.
