Loss of genetic diversity and isolation by distance and by environment in populations of a keystone ungulate species

Adaptive genetic and neutral variations are essential for maintaining population viability in changing environmental conditions. Habitat loss and fragmentation can be reflected in the patterns of genetic variation in the populations. White-lipped peccaries (WLPs, Tayassu pecari ) are wide-ranging Neotropical ungulates with important ecological roles in the ecosystem suffering local extinctions worldwide. Here, we used a RAD-seq protocol to genotype 192 individuals. After filtering, we identified sets of SNP markers (ranging from 147 to 151,792 SNPs) to assess the genetic diversity and population structure of WLPs from Pantanal, Cerrado, and Atlantic Forest in Brazil. We found signals of loss (θw
