Table 2. Microsatellites and mitochondrial mtCOI marker variation for sampling locations of A. cephalotes from the Pacific, Andean 1, and Andean 2 regions of Colombia. N is the sample size (number of nests). Na : mean number of alleles; AR : mean allelic richness; He : mean expected heterozygosity; F IS: inbreeding coefficient; HWE : Hardy-Weinberg Equilibrium test; h : number of haplotypes; Hd : haplotype diversity; π: nucleotide diversity. (***) P < 0.0001. Location abbreviations are as presented in Table 1.
