Phylogeography is a relatively young discipline that aims at explaining the geographic distributions of genealogical lineages. In doing so, the distributions of genealogical lineages of animal and plant species are correlated with historical components. A central field of phylogeographic research is speciation.
Phylogeographic studies integrate data from phylogeny, population genetics, (palaeo)geography and palaeontology to describe the extant genetic diversity as the result of a historical diversification process. Phylogeographic studies often have a direct impact on taxonomy and conservation (identification of cryptic lineages, of native or introduced animals, prediction of range shifts in changing environments).
Phylogeographic research is embedded within the Senckenberg Research Field Biodiversity and Systematics.
