中文拼音 [qúnbiànbǎifēnlǜ]
群變百分率
英文
group variation per cent-
The blastn results show that gyn - 15 is closely related to a symbiont of anemones, s. californium, and the free - living strain, gymnodinium varians. sequence comparison show that the similarities among each part of the sequences from these three strains are all above 99 %. phylogenetic reconstruction with neighbor - joining ( nj ) method using sequences of variable regions ( v1 + v2 + v3 ) of ssu rdna indicated that gyn - 15, s. californium and g. varians form a new clade with 100 % bootstrap support
以ssurdna序列中的三個可變區（ vz + vz + v3 ）和鄰接法困eighbor一joiningmethod ， nj法）構建共生甲藻屬的系統進化樹表明， gyn一巧與5 . cal扣rnium和g . varian :在共生甲藻屬內構成一個獨立的、自檢支持百分率為100 %的子類群（ clade ） ，根據這些結果可將gyn一巧初步鑒定為屬于共生甲藻屬。X2 test with 2 2 contingency table and ochiai indices were used to analyze the interspecific association of 12 dominant species of meadow community and 20 dominant species of scrub community and 18 dominant species of tree community. pearson ' s correlation coefficient and spearman ' s rank correlation coefficient were also applied to calculate correlations between species
在該地區植被的優勢種的種間關系的研究方面，運用2 2列聯表、 x ~ 2檢驗方法對群落優勢種進行總體相關性和種對間的聯結性檢驗，利用共同出現百分率jaccord指數測定種對間的關聯度，應用pearson相關系數和spearman秩相關系數刻畫種對間的數量變化關系。Several results were concluded : firstly, the population of t. jackii was decreasing sharply and its living area was contracting, so the percentage of genetic variance among t. jackii populations was lower than that within its population ; secondly, its genetic diversity index was relatively high ; thirdly, according to its gene flow index, the population disintegration of the species could be prevented by genetic communication among populations of the species ; finally, the similar index between the populations from jiangshi nature reserve and from xufan reservoir was higher than that between the populations from jiangshi nature reserve and from xufanggeng, corresponding with the fact that it is nearer between jiangshi nature reserve and xufan reservoir than that between jiangshi nature reserve and xufanggeng
2 、長葉榧的遺傳多樣性分析，分析了多態位點百分率（ percentageofpolymorphicsites ） 、 nei氏基因多樣性指數（ nei 』 sgenediversityindex ） 、 shannon信息指數（ shannon 』 sinformationindex ） 、居群間的相似系數（ geneticsimilarityindex ）和遺傳距離（ geneticdistance ） 、遺傳變異在居群間和居群內的分佈（ thepercentageofvarianceamongandwithinpopulation ）及基因流（ geneflow ） 。結論是：分佈在群體間的遺傳變異較分佈在群體內的遺傳變異小，說明該生物的分佈范圍越來越狹小。
