Gower dissimilarity is just 1 minus Gower similarity, 1 − G S. So, they are "the same", and limitations of one are the limitations of the other. Ward clustering computes cluster centroids and in order for those to be geometrically "real" it demands (squared) euclidean distances as its input. Euclidean distance is metric.

Proportional similarity index

WebbSimilarity index (community coefficient) is calculated for determining the number of species which are shared among the sites to assess the extent of variation in the species composition. Similarity index is based on percentage of matched text out of total number of words in the document. Webb18 dec. 2009 · Sample 1 or the ‘baseline’ contains four species. Samples 2, 4 and 5 also contain four species (the species richness is the same for each sample) but there are differences in species composition and total biomass.
