對所測量的形態特徵的數據在個體水平上進行聚類結果表明,同一種群的個體並不是完全有序地聚在一起,而不同種群間的個體常無序地聚在一起,同時也有一些大的表徵群不出現某些種群的個體,說明部分種群間有一定的分化,這也反映了種群內部個體間的遺傳異質性或由於種群內部微生境的差異導致的種群內個體間的形態異質性。Meanwhile, according to the requirement that the government is a primary impetus of the economic structure adjustment, the operating capability of the industry should be improved continually, and an organic ecologic community, an ordered industrial development mechanism and a harmonious industry ecosystem will be formed, and a harmoniously stable industry structure will be finally set up

Dcca排序大大提高了種與環境的相關性,更有利於排序軸生態意義的解釋,但其二維排序圖與dca排序圖相比,點的分佈更加緊湊、集中,使得群落類型間的界限變得更加模糊,因而如果同分類方法結合使用, dca在樣地和物種排序上的效果好於dcca和cca 。Using a set of primers shared by endogenous and exogenous alvs ( a > b > c, d, e ), gp85 gene was amplified by polymerase chain reaction ( pcr ) from dna extracted from common cef and exogenous alv positive samples
