Old divergence and restricted gene flow between torrent duck (Merganetta armata) subspecies in the Central and Southern Andes.

ABSTRACT:

Aim

To investigate the structure and rate of gene flow among populations of habitat-specialized species to understand the ecological and evolutionary processes underpinning their population dynamics and historical demography, including speciation and extinction.

Location

Peruvian and Argentine Andes.

Taxon

Two subspecies of torrent duck (Merganetta armata).

Methods

We sampled 156 individuals in Peru (M. a. leucogenis; Chillón River, n = 57 and Pachachaca River, n = 49) and Argentina (M. a. armata; Arroyo Grande River, n = 33 and Malargüe River, n = 17), and sequenced the mitochondrial DNA (mtDNA) control region to conduct coarse and fine-scale demographic analyses of population structure. Additionally, to test fo
