Toward an organismal, integrative, and iterative phylogeography

Phylogeography involves the analysis of gene genealogies in a spatial context, to infer the historical processes that have shaped the current population structure and distribution of organisms. The field has expanded rapidly in the last three decades, triggered by important technical and methodological advances. However, these technical improvements have not been paralleled by major changes in theoretical paradigms. I suggest that phylogeographic techniques are underutilized, and that adopting an organismal, integrative, and iterative research program in phylogeography will reinforce the explanatory power of the discipline.
