魚芒科、棘脂?科、叉尾?科、長臀?科、刀鯰科與鬍子鯰科在三種方法構建的分子系統樹中均結合在一起，形成一大單系群； ?科均與來自中國的刀鯰科魚類聚在一起；粒鯰科與鈍頭跪科也均聚在一起；但鯰科、 ?科和油鯰科的系統發育位置不定。The results show that ( 1 ) loops are in general more variable than stems, and in loops a strong adenine bias are observed : ( 2 ) there does not exist a saturation effect in stems, loops or all positions of the 16s rrna gene fragments : ( 3 ) in the molecular cladogram, bagarius forms a sister group with glyptothorax, and euchiloganis forms a sister group with pareuchiloglanis, and exostoma forms a sister group with glyptosternum : ( 4 ) the phlogenetic positions of pseudecheneis, exostoma and glyptosternum are not recognized ; the glyptosternoid fishes are not monophyly although they are defined by 13 osteological apomorphies ; the incongruence of cladograms between molecular and morphological sets may be caused by less informative sites of the 550 homologous sites ; ( 5 ) e. davidi and e. kishinouyei could be the same species according to the genetic distances ; p. sinensis and p. anteanalis could be too
結果表明： （ 1 ）環區平均變異位點較莖區多，有很強的a偏好性； （ 2 ）沒有替代飽和現象； （ 3 ）分子系統樹上?屬和紋胸?屬構成姐妹群，石爬?屬和?屬構成姐妹群， ?屬和原?屬構成姐妹群； （ 4 ） ?屬、原?屬和褶?屬的系統發育位置不定， ? ?魚類並未形成一個單系類群；可能的原因是所得到的16srrna基因片段信息位點太少； （ 5 ）青石爬?和黃石爬?可能是同一物種，中華?和前臀?可能是同一物種。In nature conditions, without the injection of the extraneous hormone, the females and males of f _ 9 - f _ 12 could mate each other to produce new next generation of tetraploids. with the stable genetic tetraploidy and the fertility in the nature environments, this allotetraploid population possessed the key factors to form a new species with 200 chromosomes
F _ 9 ? f _ （ 12 ）染色體數目的穩定性和正常的性腺結構以及自然條件下的生殖傳代行為，說明該異源四倍體鯽鯉已成為一個染色體數目為4n = 200 、遺傳性狀穩定的新型四倍體魚群體，具備形成一個新的種群所需的關鍵因素。There are different kinds of villas with foreign style, some special ethnic villages, hot spring pools, spectacular forests and etc. all these special and stuff attract thoundsands of travelers come here for traveling
島內的景色也十分獨特，各種異國情調的別墅群，別具風採的民族村，天然形成的溫泉泳池，蔚為壯觀的紅樹林，飲譽中外的鮑魚龍蝦，也同樣令遊人目不暇接。Multivariate morphometrics was conducted on the endemic asian genus sinibrama wu, 1939 in east asia in order to investigate the morphological variations among the 4 nominal species and subspecies known from south china. principal component analysis ( pca ) was performed respectively for seven meristic and thirty - two morphometric characters that were based on 224 specimens
運用多變量形態度量學方法，研究東亞特有魚類類群?華鯿屬魚類的形態差異，對其在分類學上存在疑問的物種的不同地理居群的18個框架測量距離、 14個常規測量距離和7個可數性狀進行了主成分分析。All patches adjacent to water are excotone and they have twist edges and narrow figure, which is suitable with the function of the frequency of exchanging the matter and energy, what ' s more, these patches are mixture in the plant community styles, which is according with the importance character of the excotone which is that many system coexist. 3 ) : the dissimilarity of plant community is key factor in composing the landscape heterogeneity
鄰水斑塊邊界曲折，形狀狹長，多為混合型斑塊，這與生態交錯帶多系統共存特性是相適應的。樹種結構組成差異是構成花港觀魚公園綠地景觀異質性的主要因素，不同木本植物群落類型在花港觀魚公園不同綠地斑塊類型中交錯分佈，同一斑塊類型內部群落相異性指數較高。In a word, the landscape heterogeneity exist in different scales and so the green space has a landscape pattern which is much favor to the stability of ecosystem. 4 ) : its green patch ' s figuration index and fractal index are correlating with its tree diversity index and the shape design of different styles patches in this park is adapted to the planning of its trees diversity. 5 ) : its gr een patch ' s figuration index and fractal index are not correlating with its plant community dissimilarity index and so the design of the landscape heterogeneity in the interal patch is not suitable for its pattern
花港觀魚公園綠地景觀格局參數中斑塊形狀系數與分維數都與各斑塊樹種多樣性指數表現出相關性，滿足了生態系統空間相關性的要求。花港觀魚不同類型綠地斑塊形狀與樹種多樣性配合設計是成功的。花港觀魚綠地不同類型斑塊內部群落相異性指數與其對應的斑塊格局參數沒有呈現相關性，這個綠地生態系統的植物群落差異性屬性不具有空間相關性，花港觀魚綠地斑塊內部異質性設計與其景觀格局不匹配。What makes this island special is that it is the only oceanic island not connected to the continental shelf in malaysia rising 2, 000 feet 600 meters on a limestone pinnacle that mushrooms out near the surface. pulau sipadan have the largest variety of soft corals in the world. turtles swim and frolic freely in the waters around sipadan and divers will find lobster, barracudas, beautiful coral fishes and sometimes even sharks swimming by
