Fig. 21. A in Systematics Of Funnel-Eared Bats (Chiroptera: Natalidae)

Fig. 21. A, Plot of means (black dots), two standard deviations around the mean (gray bars), and two standard errors of the mean (vertical black lines) of greatest skull length of Natalus espiritosantensis from five geographic areas: (A) Bolivia (5 females, 6 males); (B) SW Brazil [Mato Grosso do Sul], Paraguay (4 females, 6 males); (C) SE Brazil (Espirito Santo, Goiás, Minas Gerais, São Paulo; 7 females, 7 males); (D) NE Brazil (Ceará, Bahia, Rio Grande do Norte; 4 females, 2 males); (E) N Brazil (Pará; 2 males). Although the observed mean greatest skull length of males from NE Brazil was smaller, the difference was not statistically significant (MANOVA, P. 0.01). B, Plot of canonical scores for 6 cranial measurements of N. espiritosantensis from five geographic areas (same as above). Variable loadings are listed in table 12. The lack of morphometric separation between distant geographic units of N. espiritosantensis is congruent with the morphological homogeneity of the species (see text).
