  1. All samples were grouped according to (A) lake/river from which individuals were collected, (B) the freshwater basin containing each lake/river, and ocean (Pacific or Atlantic) into which each basin, (C) currently drains, or (D) histocially drained [i.e. ancient refers to the conditions before the last glacial maximum (LGM) approximately 10,000-20,000 BP]. Further post-hoc regional analysis was conducted for a subset of collection locations in Chile between latitudes 34°S and 40°S. We grouped each population as "coastal" or "Andean" for AMOVA analysis based on two criteria: (2A) location of headwaters and (2B) location of collection site (Table 1). Variation is reported as a percentage of the total with degrees of freedom (d.f.).
