Data from: Semicircular canals in Anolis lizards: ecomorphological convergence and ecomorph affinities of fossil species
Anolis lizards are a model system for the study of adaptive radiation and convergent evolution. Greater Antillean anoles have repeatedly evolved six similar forms or ecomorphs: crown-giant, grass-bush, twig, trunk, trunk-crown and trunk-ground. Members of each ecomorph category possess a specific set of morphological, ecological and behavioural characteristics which have been acquired convergently. Here we test whether the semicircular canal system—the organ of balance during movement—is also convergent among ecomorphs, reflecting the shared sensory requirements of their ecological niches. As semicircular canal shape has been shown to reflect different locomotor strategies, we hypothesized that each Anolis ecomorph would have a unique canal morphology. Using three-dimensional semilandmarks and geometric morphometrics, semicircular canal shape was characterized in 41 Anolis species from the Greater Antilles and the relationship between canal shape and ecomorph grouping, phylogenetic history, size, head dimensions, and perch characteristics was assessed. Further, canal morphology of modern species was used to predict the ecomorph affinity of five fossil anoles from the Miocene of the Dominican Republic. Of the covariates tested, our study recovered ecomorph as the single-most important covariate of canal morphology in modern taxa; although phylogenetic history, size, and head dimensions also showed a small, yet significant correlation with shape. Surprisingly, perch characteristics were not found to be significant covariates of canal shape, even though they are important habitat variables. Using posterior probabilities, we found that the fossil anoles have different semicircular canals shapes to modern ecomorph groupings implying extinct anoles may have been interacting with their Miocene environment in different ways to modern Anolis species.

Fig. 8 in A Comprehensive Phylogeny of Tettigoniidae (Orthoptera: Ensifera) Reveals Extensive Ecomorph Convergence and Widespread Taxonomic Incongruence
Fig. 8. Convergence in the false-leaf katydids (Pseudophyllinae). Four distinct and distantly related lineages are currently described under Pseudophyllinae. (A) Simoderini is an Afrotropical (Malagasy) tribe that resulted from an early divergence from the remaining Phaneropteroid clade. (B) Ischnomelini is a New World tribe of false-leaf katydids that are recovered as sister to the remaining katydids in the Mecopodinae group. (C) The Australian Phricta (Redtenbacher, 1892) is nested within the Australasian mecopodine tribe Sexavaini. (D) The remaining katydids make up the Pseudophyllinae group. Posterior probabilities over 90 are marked with a circle at the node. Photo credits are as follows: (A) Orthoptera species file online, (B) Joseph Mugleston, (C) Neil Hewett, (D) Tom Murray.
Figure 5 in Phylogeny, taxonomic reassessment and 'ecomorph' relationship of the Orientallactaga sibirica complex (Rodentia: Dipodidae: Allactaginae)
Figure 5. Variation in the shape and principal component analysis of the dorsal and ventral views of the cranium and lateral views of the mandible in voucher specimens. Principal component plots of the dorsal, ventral and mandible cranium are given in (A), (B) and (C), respectively. Canonical variant plots of the dorsal, ventral and mandible cranium are given in (D), (E) and (F), respectively. The data points on these plots are coloured according to the taxonomic status based on the phylogenetic tree. The ellipses give 90% confidence equal frequencies for the four phylogenetic groups.
