UPGMA cluster analysis

Figure 4 Dendrogram of UPGMA cluster analysis of representative isolates from different hosts of the six European Epichloe spp E. clarkii is sexually compatible with the E. typhina mating population, but is characterized by a distinct morphology. The distance measure is based on Nei s genetic identity using allozyme variation at 12 loci. (Modified from Leuchtmann and Schardl, 1998.)...

Fig. 1 Dendrogram based on cluster analysis of digitized (GTG)j-PCR fingerprints of type, reference and Bryndza cheese strains. The dendrogram was constructed using the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) using correlation levels expressed as percentage values of the Pearson correlation coefficient. Numbered clusters (1-9) correspond to identified species of Enterococcus sp. and Lactococcus sp.

Figure 30.1 Cluster analysis on presence-absence of genera UPGMA, Jaccard coefficient used. Data from Potter and Boucot (1992 table I) and from the Bardahessiagh Formation (Candela, 2000) see Potter and Boucot (1992) for key to the assemblages names.

FIGURE 16.4 Results of a similarity-based compaiison producing a distance square matrix (lower window) on which two different clustering methods were applied. The top-left window represents a UPGMA tree where one additional criterion was printed (bands of one-dimensional electrophoresis profiles). The top-right window is a three-dimensional representation of the OTUs presented on the distance matrix below that have been reordered using the principal coordinate analysis ordination method.
