Figure 1.

Position of the 316 tortoises blood-sampled on EspaƱola in 2003. Circles represent individuals. The star corresponds to the position of individual E1465. The contour dotted-line indicates the 100 meter altitude level. The concentration of sampled individuals in two main areas reflects the localization of suitable habitat where the vast majority of tortoises congregate.
