Biogeography is an integrative discipline, as is reflected in familiar combinatorial neologisms including bio⋅geography itself and disciplines such as phylo⋅geography and macro⋅ecology. One recently introduced term — geo⋅genomics — represents interdisciplinary approaches using “large-scale genetic data to test or to constrain geological hypotheses” (sensu Baker et al. 2014, p.38). Geogenomics is eight years young, arguably in its foundational phase, and its relationship with other disciplines of biogeography is developing. This virtual issue reviews the origins of geogenomics, compiles a suite of new papers that reflect geogenomics’ current purview (as practiced by biogeographers), and considers its potential to change the way we combine genetics and geology for answering biogeographic questions.
