Genetic Admixture In Multidimensional Niche Space: Asymmetrical Niche Similarity Promotes Gene Flow In Armadillos (Dasypus Novemcinctus), Maria Arteaga, John Mccormack, Luis Eguiarte, Rodrigo Medellín

We unite genetic data with a robust test of niche divergence to test the hypothesis that patterns of gene flow between two lineages of the nine-banded armadillo are influenced by their climatic niches. We collected Geographical Information System (GIS) data on climate using locality information from 111 individuals from two lineages that had associated genetic material. We tested whether niches of these lineages were more conserved or divergent than the background environments of their geographic ranges and found evidence for niche conservatism on two axes and no evidence for divergence on any axis. To address the role of niche similarity …
