[[Catch composition of monofilament gillnet netting with different mesh sizes in Qingcaosha Reservoir, Shanghai, China].

During 2010 to 2012, fish diversity in Qingcaosha Reservoir was studied based on gillnets (multi-mesh monofilament gillnets and single-mesh trammel gillnets), electric fishing, bottom trawl and cage. The investigation collected a total of 34 fish species, belonging to 8 orders, 12 families. Cypriniformes contained the largest number of species (19 species) in the collection, followed by Perciformes (6 species).

[Simulation of Stipa purpurea distribution pattern on Tibetan Plateau based on MaxEnt model and GIS].

The impact of climate change on species distribution is a hot issue in biogeography research. This study utilized the constructive species Stipa purpurea as the research object, which was widely distributed in alpine meadow of the Tibetan Plateau, investigated its distribution in the Tibetan Plateau through the field survey and herbarium search, and used MaxEnt model to simulate its historical, current and future distribution trends to analyze its distribution pattern in each historical period and explore the cause of species distribution changes. Research results showed that diversity of Stipa species in alpine grassland of the Tibetan Plateau was high, its main distribution area was the hinterland of the Tibetan Plateau and areas along the Himalaya, and its distribution was strongly affected by precipitation of warmest quarter, precipitation of wettest quarter and annual precipitation.

[Predicting the dispersal routes of alpine plant Pedicularis longiflora (Orobanchaceae) based on GIS and species distribution models].

Pedicularis longiflora experienced extensive populations' expansion in Quaternary, but the dispersal corridors were still unclear. According to the distribution patterns of haplotypes based on chloroplast DNA variation, the dispersal routes were predicted using species distribution models (MXENT) and the least-cost path method. Two possible dispersal routes from the southeastern part of Tibetan Plateau (TP) to interior were identified.

[Macrozoobenthos community structure and its indicative significance in water quality bioassessment of Fenshuijiang Reservoir, Zhejiang Province of East China].

A monthly investigation was conducted on the macrozoobenthos at 7 stations of Fenshuijiang Reservoir in Zhejiang Province of East China from November 2008 to October 2009. A total of 37 taxa were collected, most of which belonged to Oligocheata and Chironomidae. Limnodrilus hoffmeisteri was dominant in spring, summer and autumn, and Chironomus gr.

[Structure and function of Fenshuijiang Reservoir ecosystem based on the analysis with Ecopath model].

Based on the 2008-2009 survey data of fishery resources and eco-environment of Fenshuijiang Reservoir, a mass balance model for the Reservoir ecosystem was constructed by Ecopath with Ecosim software. The model was composed of 14 functional groups, including silver carp, bighead carp, Hemibarbus maculates, Cutler alburnus, Microlepis and other fishes, Oligochaeta, aquatic insect, zooplankton, phytoplankton, and organic detritus, etc. , being able to better simulate Fenshuijiang Reservoir ecosystem.

[Macrobenthos community structure and its relations with environmental factors in Taihu River basin].

An investigation was conducted on the macrobenthos at 37 sampling sites in the Taihu River basin in August 2009 and May 2010. A total of 69 macrobenthos species were collected, of which, 15 species (21.7% of the total) were oligochaetas, 16 species (23.

[Phytoplankton community structure in Mingzhu Lake of Chongming Island, Shanghai].

A preliminary study was conducted on the phytoplankton community structure and the annual variation of species diversity in Mingzhu Lake of Chongming Island from January to December 2007. A total of 120 phytoplankton species belonging to 8 phyla and 63 genera were collected, among which, Phormidium tenue, Meismopedia tenuissima, M. convoluta, Microcystis incerta and Synedra ulna were the dominant species.

Distinct symmetry and limited peptide refolding activity of the thermosomes from the acidothermophilic archaea Acidianus tengchongensis S5(T).

Recombinant thermosomes from the Acidianus tengchongensis strain S5(T) were purified to homogeneity and assembled in vitro into homo-oligomers (rATcpnalpha or rATcpnbeta) and hetero-oligomers (rATcpnalphabeta). The symmetries of these complexes were determined by electron microscopy and image analysis. The rATcpnalpha homo-oligomer was shown to possess 8-fold symmetry while both rATcpnbeta and rATcpnalphabeta oligomers adopted 9-fold symmetry.

[Structural characteristics of chironomid community and their indicative significance in bioassessment of water quality in Mingzhu Lake of Chongming Island, Shanghai].

The structural characteristics of chironomid (Diptera: Chironomidae) community in Mingzhu Lake of Chongming Island, Shanghai, China were studied from July 2006 to April 2008. A total of eleven chironomid species belonging to 10 genera and 3 subfamilies were collected, among which, Propsilocerus akamusi and Microchironomus sp. were predominant.
