[Chapter Abstract] We investigate the genetic diversity and structure of guigna populations throughout their known distribution range by analyzing 1,798 bp of the mtDNA and 15 microsatellite loci in 116 individuals sampled from 32.5°S to 46.5°S in Chile and Argentina. MtDNA data reveals a moderate separation between northern and southern populations, supporting previously proposed subspecific partitions. Microsatellite data supports this north–south pattern of subdivision, showing also further structure detail revealing current demographically isolated groups. Spatial analysis of molecular variance shows a finer scale yet consistent population structure compared to the genetic assignment and clustering method. High positive correlations between genetic and geographic distances in both mtDNA and microsatellite loci suggest a consistent historical and contemporary isolation by distance pattern. The population structure uncovered by this study identifies at least five different Conservation Units for guigna populations throughout their distribution range in southern South America.
