Table 1 Canga areas, geographic distances and genetic differentiation of I. cavalcantei and I. marabaensis populations. The values along diagonal (in bold) are areas of Cangas (km²). Values above diagonal are the shortest distances between Canga islands (km). The pairwise genetic differentiation measured by the population descriptive statistics is shown below the diagonal. The F _ST values from the plastome (pt) gene alleles, emphasized by italics font, and internal transcribed rDNA spacer alleles (ITS2) are combined in the same cells. Asterisk are the p values: ^*<0.05; ^**<0.01; ^***<0.001.
