Fig. 8From: What you sample is what you get: ecomorphological variation in Trithemis (Odonata, Libellulidae) dragonfly wings reconsideredFrequency histograms for Trithemis forewing and hindwing shape distinctions for species preferring different landscape and water body habitats based on the direct assessment of wing-image datasets. Note the minimum extent of shape-range overlap and clear distinction exists between the central tendencies of these habitat-based wing shape differences. Statistical comparisons of the between-groups separation relative to within-groups dispersion using a bootstrapped version of Hotelling's T2 test indicate that all four comparisons are significant at well beyond the p = 0.95 confidence levelBack to article page
