A comprehensive study of the phylogeography and population genetics of the
largest wild artiodactyl in the arid and cold-temperate South American
environments, the guanaco (Lama guanicoe), was conducted to detail
patterns of molecular genetic structure related with phylogeographic
history, barriers to gene flow, to describe and contrast the evolutionary
history and patterns of gene flow among populations. Analyses of 514 bp of
mtDNA sequence and 14 biparentally-inherited microsatellite markers of 314
individuals from 17 localities throughout their current distribution
across Peru, Bolivia, Argentina and Chile confirm the well-defined genetic
differentiation and subspecies designation of populations geographically
separated to the northwest (L. g. cacsilensis) and southeast (L. g.
guanicoe) of the central Andes plateau. However, these populations are not
completely isolated, as shown by admixture prevalent throughout a limited
contact zone and a strong signal of expansion from north-to-south in the
beginning of Holocene. Microsatellite analyses differentiated 3
northwestern and 4-5 southeastern populations, suggesting patterns of
genetic contact among these populations, and identified possible genetic
refuges and source-sink patterns of gene flow at historical and recent
time scales. These results confirm that conservation and management of
guanaco should be implemented with an understanding of local population
dynamics while considering the preservation of broader adaptive variation
and evolutionary processes.
