2012-07-27Reintroduction of Tigridiopalma magnifica, a Rare and Critically Endangered Herb Endemic to ChinaThe main findings are as following:Twelve locations with populations of T. Magnifica only grows in the surface soil on stone walls or rocks under the canopy of secondary forests and plantations and has no specific associated plant species. After 11 months survival rate was 40–58% but survival was higher and plantlet crowns were larger at the lo... Tigridiopalma magnifica, a perennial herb and the only species in the genus Tigridiopalma (Family Melastomataceae) is rare, and endemic to China, where it is categorized as Critically Endangered on the national Red List. During past 7 years, Dr REN Hai and Dr. ZENG Songjun co-operated to research the reintroduction of the species. The main findi...Read More -

2012-05-31The Spatial and Temporal Patterns of Carbon Storage in forest Ecosystems in Guangdong, Southern ChinaThey found that the forest coverage percent in Guangdong increased from 37.1% in 1992 to 57.2% in 2002 while the total forest C storage in Guangdong increased from 144.73±6.20 Tg in 1992 to 215.03±8.48 Tg in 2002.The order of average forest biomass C storage increase during 1992-2002 among the four regions was Western Guangdong(。 GW)>Eastern ... Dr. REN Hai at South China Botanical Garden and Dr. CHEN Hua at University of Illinois co-operated to examine the spatial and temporal patterns of C storage from 1992 to 2002 in forest ecosystems in Guangdong, China.Read More

Albumand in water and nutrient transport in the host-parasite association. Many lysosomes present and large-scale digestion of host cells occur at the interface between the hemiparasite sandal tree and the host. Albumpenetration into the host suggested there was a function of mecha... Santalum album is a small tropical tree. This species has been utilized, cultivated and traded for thousands of years for its fragrant, perfume and medicinal purpose.For these reasons it has been extensively exploited, to the point where the wild population is vulnerable to extinction. However, the tree is an obligate root hemi-parasitic tree. C...Read More
