Classification of generalists and specialists. a The distribution of the number of environment clusters that a species belongs to was compared to the expected distribution derived from 100,000 permutations. The insets show the detailed histograms for species that belong to five or more environment clusters. b The rate of new habitat acquisition (the y-axis, “Ratio of Number of Species”), as represented by ratio of the number of species that belong to N + 1 environment clusters over the number of species that belong to N clusters, are higher than expected, especially for classified generalists (species that belong to at least five environment clusters). The x-axis indicates the number of clusters, N
