＜正＞Myospalax baileyi and Microtus oeconomus are native rodents living at Qinghai-Tibet plateau in China. Myospalax baileyi lives in burrows underground at altitude of about 32.0 m for its whole life cycle,enduring hypoxia and a～2. fold higher carbon dioxide condition;whereas Microtus oeconomus resides in meadows above 3 000 m on the Qinghai-Tibet plateau,suffering a different content of hypoxia due to the smaller depth of its caves.

The Longgan Lake is a shallow mesotrophic macrophyte-dominated lake. According to the high-resolution diatom research from its sediment core, the diatom community succession was built, and the total phosphorus (TP) and chlorophyll-a (Chl-a) concentration were quantitatively reconstructed for the past 2.00 years, based on the diatom-TP and diatom-Chla transfer functions. The shifts of diatom assemblages also mirrored the developments of aquatic plant, reflecting the characters of aquatic ecosystem evolution. The inferred epilimnetic TP concentration fluctuated within a small range of 36 to 62.g/L, indicating the lake remained a relative stable mesotrophic status in the long historical period. The periodical variations of the diatom assemblage and trophic status suggest a mitigating function of shallow macrophyte-dominated lakes to nutrient input. The changes of lakes’ trophic status don’t linearly respond to the human disturbance in the catchment. The dynamics mechanism of phosphorus in macrophyte-dominated lakes, as inferred from diatoms, will provide a scientific foundation for the prediction of trophic status change in a shallow lake, as well as the lake ecological restoration and management decisions.

The 9-bp deletion in the COII/tRNALys intergenic region (region V) of human mitochondrial DNA was screened in 152. chinese from 16 ethnic groups and 9 Han geographic groups. The highest frequency was found in populations of Miao (32.4%) and Bouyei (30.8%) from Cuizhou Province, whereas no deletion was found in Kazak population in Xinjiang. In the populations of Wa and Lahu from Yunnan Province, Uygur and Mongolian from Xinjiang, the deletion frequency was relatively low (≤4%), while in the remaining 18 groups, the frequency was moderate (6% - 2. %). Except those Hans in Xinjiang, Guizhou and that reported in Taiwan, the deletion frequency in the Han geographic groups did not show a substantial difference. However, the deletion frequency in some ethnic groups from the same geographic region or with similar ethnohistory did not show similarity. A general decrease tendency in the deletion frequency was found from south to north and from coastal to inland. The frequency of the 9-bp deletion was approximate

Wetland plays an important role in the tempo spatial evolution of climate, biogeochemistry and biodiversity of the terrestrial ecosystems of the earth. To trace the patterns of wetland changes in the past and predict the changing trends in the future in the dimension of human activities is an arduous task for geographers and ecologists. The paper describes how to combine GIS with geo informatics and geography to simulate the wetland changes happened in Jianghan Plain in the middle reaches of the Yantze River in the last 40 years, and presents the results. The environmental implications of the wetland changes are discussed.

Viruses of thermophiles are of great interest due to their roles in gene transfer, global geochemical cycle and evolution of life on earth. However, the thermophilic bacteriophages have not been studied extensively. In this investigation, a typical bacteriophage BV1 was obtained from a thermophilic bacterium Geobacillus sp. 6k512. which was isolated from an inshore hot spring in Xiamen of China. The BV1 contained a double-stranded linear DNA of 35 055 bp, which encodes 54 open reading frames （ORFs）. Interestingly, eight of the 54 BV1 ORFs shared sequence similarities to genes from human disease-relevant bacteria. Seven proteins of the purified BV1 virions were identified by proteomic analysis. Determination of BV1 functional genomics would facilitate the better understanding of the mechanism for virus-thermophile interaction.
