Data from: The influence of the arid Andean high plateau on the phylogeography and population genetics of guanaco (Lama guanicoe) in South America

Juan Carlos Marín, Benito A. Gonzalez, Elie Poulin, Ciara S. Casey & Warren E. Johnson
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...

Data from: High frequency echolocation, ear morphology, and the marine–freshwater transition: a comparative study of extant and extinct toothed whales

Carolina S. Gutstein, Constanza P. Figueroa-Bravo, Nicholas D. Pyenson, Roberto E. Yury-Yañez, Mario A. Cozzuol & Mauricio Canals
This study compares the bony ear morphology of freshwater and marine odontocetes (toothed whales). Odontocetes are unique among marine mammals in two important respects: 1) they use echolocation; 2) at least three lineages have independently evolved obligate freshwater habits from marine ancestries. Freshwater odontocetes include the so-called “river dolphins,” a paraphyletic group that each evolved convergent external morphological characters that distinguish them from oceanic dolphins (Delphinoidea). In addition to their convergent external morphology, “river dolphins”...
