FIG. 3 in Cranial shape and diet variation in Myotis species (Chiroptera: Vespertilionidae): testing the relationship between form and function

FIG. 3. Ordination plots of the first two canonical axes from two skull modules among dietary groups. A — Ordination plot of the first two canonical axes from parieto-occipital region (skull module 1) with deformation grids derived of each the canonical axis. The horizontal arrow indicated the direction of change in M. vivesi with respect to the consensus shape. The vertical arrow indicated the directions of change in insectivores with respect to the consensus shape; B — Ordination plot of the first two canonical axes from frontal-maxillary region (skull module 2) with deformation grids derived of each the canonical axis. The vertical arrow indicated the direction of change in M. vivesi with respect to the consensus shape. The horizontal arrow indicated the directions of change in facultative piscivores with respect to the consensus shape. Three diets were compared: insectivorous species (×), and facultative piscivorous species (●) and piscivorous species (é)
