%X Coatis (Procyonidae; Nasua) are considered the only truly social meso-carnivore mammals in Neotropical forests. In Mexico, white-nosed coatis (Nasua narica) are suspected to have undergone population reduction due to habitat loss and fragmentation and led to a lack of genetic adaptability and genetic isolation throughout its range. We examined patterns of genetic diversity and connectivity of five populations of Nasua narica distributed throughout Mexico (n = 60) by sequencing an ¡Ö 800 bp fragment of the mitochondrial cytochrome-b gene and also by screening 12 microsatellite loci. We found moderate to high levels of genetic variability for both genetic markers. We recorded twenty-two different cytochrome-b haplotypes throughout the 5 sampled areas and found that each of the sampled population of white-nosed coatis in Mexico harbors unique haplotypes and only three haplotypes were shared among two different populations that were closer geographically. All populations had high haplotype diversity (h) (0.968 ¡À 0.008 (SD)) but lower levels of nucleotide diversity (¦Ð) of 0.007 ¡À 0.001 (SD). All microsatellite loci were polymorphic in all of the populations and the mean number of alleles per locus was 5.033 ¡À 1.545 (SD) with expected (HE) and observed (HO) heterozygosity values of 0.774 and 0.664, respectively. However, low Wright F statistic values suggest the existence of a reduced heterozygosity (FST = 0.203, FIS = 0.134 and FIT = 0.310). Significant differences between the five populations confirmed isolation by distance, which suggests genetic structure among five subpopulations.
