Fig. 41 in Systematics Of Funnel-Eared Bats (Chiroptera: Natalidae)

Fig. 41. Variation of forearm length in Natalidae in relation to geographic distribution. Vertical gray bars represent the observed range of variation per species per region and the horizontal black line represents the median. Large gray rectangles frame populations that occur in sympatry. Sample sizes: Bahamas (Ctu, 53; Nyl, 45); Cuba (Npr, 51; Cma, 20; Nyl 24); Hispaniola (Nma, 34; Cmi, 6); Jamaica (Nja, 21; Cmi, 48); SAP 5 San Andrés and Providencia islands, Colombia (Nme, 7; Cmi, 36); M-CA 5 Mexico–Central America (Nme, 298; Nla, 33); SAN 5 South America N of the Amazon (230); SAS 5 South America S of the Amazon (37); LA 5 lesser Antilles (65). There is no overlap in forearm length neither among genera nor among insular populations that occur in sympatry. Representatives of the composite fauna of San Andrés and Providencia islands (i.e., the West Indian derived C. micropus, and the continental derived N. mexicanus) show the least amount of difference in forearm length among sympatric members of these two genera.
