Table 3.
Factor loadings, eigenvalues and percentage of total variation explained by the two significant ‘axes of territoriality’ extracted by a phylogenetic PCA (λML = 0.849). Bold denotes factor loadings > 0.5, which were used to interpret the two principal components. BGE, between-group encounter.
