Species composition and diversity of Euphausiacea in the East China Sea
Based on the data of four seasonal oceanographic censuses in the East China Sea (23°30′～33°00′N, 118°30′～128°00′E) in ～, the species composition and the diversity of Euphausiacea were discussed as well as their relations with environmental variables. Results showed that there were totally 23 different species of Euphausiacea, in which 16 occurred in spring and autumn respectively; 15 were present in summer and only 10 were observed in winter. According to the calculated alternation fraction (R), the species composition showed a clear seasonal alternation with the changes ofseasons. Moreover, the environmental variables had different impacts on the distribution of Euphausiacea in different seasons. The distribution in summer was not significantly related to water temperature and salinity. However, the surface salinity was a major determinant of the distribution in spring. In autumn, both surface and bottom temperatures were influencing factors. The distribution in winter depended on salinity at the surface and 10 m depth as well as the temperature at 10 m depth. Regarding to the seasonal variation of species composition, the variations in spring, summer and autumn were not so significant as those in winter. Except in summer, the species number changed with synchronous water temperature and salinity, as a result of the presence of warm currents in the East China Sea and the habitability of the dominant species. Since Euphausiacea tend to agglomerate, the distribution of different species was uneven, which was the major reason for the low diversity of Euphausiacea in the East China Sea.

There are 3048 species offish occurring in the China Seas (CS), of which at least 2321 species are found in the South China Sea (SCS), belonging to 35 orders, 236 families and 822 genera. The fish species diversity is analyzed in this paper based on biogeography, biostatisties, fishing methods, etc. It is found that the regional environment, especially biological factors, plays an important role in the distribution of faunas, and there are two fish faunas in the SCS, one in the north and another in the center and south. This regional division is of value for sustainable fishery production and efficient management of fishery resources.

Diversity and regeneration of woody species were investigated in two ecological niches viz. gap and intact vegetation in old-growth seasonally dry Shorea robusta (Gaertn. f.) forests in Nepal. We also related varieties of diversity measures and regeneration attributes to gap characteristics. Stem density of tree and shrub components is higher in the gap than in the intact vegetation. Seedling densities of S. robusta and Terminalia alata (B. Heyne ex Roth.) are higher in the gap than in the intact vegetation, while contrary result is observed for T. bellirica (Gaertn. ex Roxb.) and Syzigium cumini (L. Skeels) in term of seedling density. The complement of Simpson index, Evenness index, and species-individual ratio in the seedling layer are lower in the gap than the intact vegetation. Gap size can explain species richness and species establishment rate. Gaps created by multiple tree falls in different years have higher seedling density of S. robusta than gaps created by single and/or multiple tree falls in the same year. In conclusion, gaps maintain species diversity by increasing seedling density, and favor regeneration of Sal forests. In addition to gap size, other gap attributes also affect species diversity and regeneration.

Look! There is a rainbow! On the first day of my university life, when I walked into the campus, there was a rainbow bridging over the fountain, I hadn’t seen rainbow for a long time. I was so excited, and leaped high with joy. My ponytail danced with my happiness. It was a propitious sign indicated that my life in university would be colorful, and actually it is!After my entry into university, I found my life so busy. What I should do is not only gaining the scholarship but also being a good monitor and leader of shanghai university percussion band. I got the 1st and 2nd price of scholarship in my 2 years of study. I organized charity donations for schoolmates with financial difficulty or disease. Every week, I give drum lesson to new members of our percussion band. And there are always a lot of non-business performances, such as entertaining guests, celebrating party, cultural exchange with foreign students delegations and their bands. Of course, part-time job is indispensable in my vacations. I ask for no payment but aim at getting accustomed to the society.
Sometimes, my friends advise me not to tire myself out with such a tight schedule. I wake up before the rooster crow, and continue working till very late when others are enjoying their sweet dreams. Every time I come back from the rehearsal of percussion band, I have to finish my homework with the help of my own charged light because of the blackout in out dormitory. Maybe such kind of life is something like an ascetic, but we should work hard and try hard in our youth, aren’t we?
When I represented shanghai university to take part in the POND’s new century lady competition held in May, when I show off on the stage, when I emerged as “the girl of vitality”, I made use of every bit of time to compensate the classes I had missed, I made use of every chance to learn from other girls with vitality, versatility and intelligence, I made use of this opportunity to present our university students’ state
Molecular genetic diversity of bacteria in the bottom section of arctic sea ice from the Canada Basin
PCR-DGGE approach was used to analyze bacterial diversity in the bottom section of seven arctic sea ice samples colleted from the Canada Basin. Thirty-two 16S rDNA sequences were obtained from prominent DGGE bands. The closest relatives of these sequences are found to be those of cultivated or uncultured bacteria from antarctic or arctic sea ice. Phylogenetic analysis clustered these sequences or phylotypes within α- proteobacteria, γ-proteobacteria and CFB (cytophaga-flexibacter-bacteroides) group. Sequences belonging to γ-proteobacteria were dominant and members of the CFB group were highly abundant. It was suggested that the CFB group was the representative of the bottom section of sea ice samples.
