Preface

Part 1: History and conceptual background



This section introduces the meaning and purview of phylogeography, describes the history of the discipline on both the empirical and theoretical sides, and highlights novel perspectives that the field has spawned. It concentrates in particular on the tight connections between genealogy and population demography, and the nonequilibrium (i.e., historical) nature ofpopulation genetics.

Part 2: Empirical intraspecific phylogeography



Theories of lineage sorting and the coalescent indicate that a great diversity of intraspecific phylogeographic patterns might be anticipated as functions of species' varied demographic histories. Empirical findings (primarily from mt DNA assays) appear to have borne this out. This section illustrates the wide assortment of idiosyncratic phylogeographic patterns documented to date. It asks whether general trends nontheless have emerged that carry predictive power in relating comparative phylogeographic patterns across taxa to particular categories of natural history or environmental circumstance.

Summary

Part 3: Genealogical concordance: Toward speciation and beyond



Much of the effort of empirical phylogeography summarized in Part 2 involved molecular examinations of the genealogical histories of single genes (usually mtDNA) in particular species, one at a time. The third section of this book extends such approaches to multiple genes, multiple codistributed species, and comparisons with more traditional kinds of biogeographic data. Such extensions into comparative phylogeography introduce several distinct aspects of genealogical concordance germane to evolutionary inference at the scale of landscape history. Interpretations of phylogeographic population structure at the interspecific level often grade into broader issues of species concepts and taxonomic assignments, so this concluding section also addresses these issues in greater detail. In particular, phylogeographic studies can be highly informative about population demography, geography, and temporal durations of the speciation process.
