Phylogeography of northern North America with insights from paleontological, geological, and molecular data - Introduction.

Recent analytical, methodological and technological advances have brought new insights to our interpretation of the phylogegeographic patterns of plant taxa. This symposium examines phylogeographic patterns of plant species from glaciated areas of North America, a geographic region that has been relatively neglected in phylogeographic analyses to date. New phylogeographic approaches are presented which incorporate spatio-geographic and paleoclimatic modeling, palynological and macro-fossil data, and paleoecology and paleoclimatology studies. Integrated with molecular data, which reveal relationships in closely related taxa, these multiple sources of information provide a means of better interpreting recurrent biogeographic patterns in northern North America. The second half of the symposium is devoted to case studies focused on a variety of important north boreo-temperate taxa from, for example, Asteraceae, Rosaceae, and Salicaceae. Hypotheses of postglacial colonisation and migration patterns are evaluated taking into consideration historical, ecological and genetic processes to explain present distributions and to test refugia hypotheses.
