  1. The complete nucleotide sequence of the mitochondrial genome of f. limnocharis was detailedly compared with those of 5 other amphibians. the nucleotide sequences of 22 trna encoded by 6 amphibians mitochondrial genomes were combined and aligned to the homologous sequences of the 11 veterbrate taxa. using teleosts as outgroup, the phylogenetic analyses results show that mp, nj and ml trees all strongly support the monophyly of living amphibians with respect to other living tetrapods and favor a sister group relationship for caecilians and salamanders

    我們在測定了澤蛙線粒體全基因組序列的基礎上,與已知其它的5種兩類進行詳細的比較分析,同時選擇了11種高等脊椎的線粒體全基因序列,以硬骨魚類做外,用22個trna基因合併數據進行系統發生重建分析,結果明mp 、 nj和ml樹都強力地支持現生兩為單系並且蠑螈類和蚓螈類為姐妹關系(自引導值分別為92 、 99 、 100 ) 。
  2. In summary, the exotic species can affect native bird species in four main ways, 1 ) predation of birds or eggs by the exotic mammals ; 2 ) competition for habitats and foods with exotic birds, and loss of genetic diversity by hybridization with the closely - related exotic species ; 3 ) direct and indirect alterations of native habitats and food resources, and predation by the exotic invertebrates ; and 4 ) loss and fragmentation of habitats for native birds through altering species composition and structure of native plant communities by exotic plants

    外來生對鳥類的影響主要現在以下幾方面: ( 1 )外來哺乳對成鳥、幼鳥或鳥卵的捕食作用; ( 2 )外來鳥類與本地鳥類競爭息地和食資源,與當地的近緣種雜交而造成基因流失; ( 3 )外來無脊椎改變本地鳥類的息環境和食狀況,甚至直接捕食本地鳥類; ( 4 )外來植入侵改變入侵地的植落組成和結構,造成本地鳥類的息地喪失或破碎化,並通過改變入侵地生態系統的食鏈結構而對高營養級的鳥類產生影響。
  3. Compared with the studies on macrofauna in bohai sea and southern yellow sea, the macrobenthic abundance and biomass in jiaozhou bay were less than those of two seas. but the macrobenthic secondary production in jiaozhou bay was more than that of the bohai sea. using the sieves with 0. 5mm aperture mesh in sorting quantitative macrobenthic samples shows more advantages than that of using sieves with 1mm aperture mesh

    本研究同時使用了1mm和0 . 5mm孔徑的網篩進行大型底的分選,通過兩種孔徑網篩篩留大型底的種數、豐度和生量比較,說明0 . 5mm孔徑的網篩對大型底分選在種類和數量組成優於1mm孔徑網篩,使落結構更完整,樣品代性更高。
