Figure 1 in Using 3D geometric morphometrics to aid taxonomic and ecological understanding of a recent speciation event within a small Australian marsupial (Antechinus: Dasyuridae)
Figure 1. Distribution map of the specimens used for this study. Labelled are Antechinus stuartii south, A. stuartii north, A. subtropicus, specimens of unknown identity within the A. stuartii–A. subtropicus species complex, the holotype of A. subtropicus and the neotype of A. stuartii. All figures in this paper are labelled: A. stuartii south in orange, A. stuartii north in pink and A. subtropicus in green. The phylogeny is adapted from Mutton et al. (2019).
Figure 2. A in Using 3D geometric morphometrics to aid taxonomic and ecological understanding of a recent speciation event within a small Australian marsupial (Antechinus: Dasyuridae)
Figure 2. A, box plot and dot plot of centroid size labelling each clade as per Figure 1. Centroid size differences were clear only between the larger Antechinus subtropicus and the smaller A. stuartii (both mean comparisons between A. subtropicus and the two clades of A. stuartii were significant; P = 0.003), but not between A. stuartii south and A. stuartii north (P = 0.282). B, allometry plot consisting of centroid sizes versus shape scores obtained from the regression of shape on size (Drake & Klingenberg, 2008).

Figure 2 in Cranial variation between coastal and offshore boưlenose dolphins, Tursiops truncatus (Cetacea: Delphinidae) in Ecuador and the Mediterranean: a three-dimensional geometric morphometric study
Figure 2. Three-dimensional landmarks used in this study, showed in dorsal (A), ventral (B), lateral (C), and occipital (D) aspects of the boưlenose dolphin skull.
Figure 6 in Cranial variation between coastal and offshore boưlenose dolphins, Tursiops truncatus (Cetacea: Delphinidae) in Ecuador and the Mediterranean: a three-dimensional geometric morphometric study
Figure 6. Ward's clustering analysis based on the first 55 PCs of principal component analysis (PCA) Euclidean distances: A, automatic landmarking; B, manual landmarking. Location shown indicates the origin of the majority of specimens within each cluster.
Figure 1 in Cranial variation between coastal and offshore boưlenose dolphins, Tursiops truncatus (Cetacea: Delphinidae) in Ecuador and the Mediterranean: a three-dimensional geometric morphometric study
Figure 1. Map showing sample number of common boưlenose dolphin individuals per location. Offshore populations in dark red, coastal populations from Guayaquil (Ecuador) in purple, coastal populations from the Mediterranean Sea in orange.
