FIGURE 16 in Larval anatomy of Andean tadpoles of Telmatobius (Anura: Ceratophryidae) from Northwestern Argentina
FIGURE 16. Modeled suprarostrals along the first three eigenshapes, at minimum, 25%, 50%, 75%, and maximum scores. Open curves, more evident on ES2 models, are due to the modeling technique, which generates mathematically constructed shapes (MacLeod 1999; Krieger et al. 2007). Figures within the squares at right show overlapped curves to highlight places where the shape change is more evident: ES1 shows a change at the corpus-ala ventral junction, ES2 is mainly associated with alae shortening and dorsolateral process orientation, and ES3 reveals a slight change on corpusala dorsal junction. Note also the minimum number of points calculated by EEA to describe each outline segment (i.e., 3, 13, 23, 28, and 19).
FIGURE 15 in Larval anatomy of Andean tadpoles of Telmatobius (Anura: Ceratophryidae) from Northwestern Argentina
FIGURE 15. Extended eigenshape analysis on suprarostral cartilages. A high superposition among specimens is evident, and ES3 helps to discriminate species that overlap on ES1-ES2 morphospace. The classification according to biogeographical regions is based on Laurent (1970) and Olson et al. (1998).
FIGURE 14 in Larval anatomy of Andean tadpoles of Telmatobius (Anura: Ceratophryidae) from Northwestern Argentina
FIGURE 14. Principal component analysis on the combined matrices of chondrocranium and hyobranchial skeleton shape variables (almost identical to the PCA on the hyobranchial skeleton matrix). The discrimination of species is clearer on the PC2; grids depict modeled specimens on this axis, with maximum (top) and minimum (bottom) scores. Shape change implies a slight enlargement of the relative size of the branchial basket (enclosed area), and a widening of the buccal pocket (arrow). The classification according to biogeographical regions is based on Laurent (1970) and Olson et al. (1998).
