Both dendrograms generated using the Raup--Crick and Simpson similarity coefficients (Fig.
Analysis of morphological data through cluster analysis groups species together based on their overall similarity and this grouping can be presented in form of cladograms, dendrograms, or even phylogenetic trees.
Based on the BOX-PCR dendrogram constructed, it was found that the 29 isolates were genetically diverse and heterogeneous.
A dendrogram was prepared on the basis of a similarity matrix using the UPGMA algorithm and separated the 24 genotypes into four groups.
The clustering steps of four different methods (single, complete, k-min and k-max linkage) for the datasets given in Table I are summarized via dendrograms in Figure 6 and Figure 7.
Numerical Taxonomy and Multivariate Analysis System--NTSYS (Exeter Software version 2.1, 2000) (ROHLF, 2000), the coefficient of cophenetic correlation (r) between the original genetic distances and those represented by the dendrogram among the genotype pairs was calculated according to SOKAL & ROHLF (1962).
There was a significant difference between the secondary forest and pine plantation in terms of ant assemblages (ANOSIM; Global R = 0.630, p = 0.001) and other arthropod assemblages (ANOSIM; Global R = 0.603, p = 0.001) which is also clearly seen in NMDS ordinations (Figures 4(a) and 4(b)) and dendrogram (Figures 5(a) and 5(b)).
After analyzing all three dendrograms, the clustering shown in Figures 6-8 appears reasonable, although the dendrogram in Figure 6 appears to be more consistent from the clinical point of view, because one cluster is formed by strains belonging to one biotype.
A dendrogram was prepared using the similarity coefficient of RAPD marker.
Based on the Mahalanobis distance matrix obtained from the original data transformed into Lorey height, the single, complete and average linkage methods and Ward's method were obtained, resulting in the respective dendrograms (Figures 1 and 2).
