Summary

Yeasts, as predominantly unicellular fungi, differ profoundly from other fungi in terms of ecological adaptation. Yeasts prefer liquid or surface environments. Their thallus combines both growth and dispersal functions. Notwithstanding these important differences, it is hoped that many concepts that are relevant to the ecology and biogeography of ascomycetous yeasts will also find application for other fungi and contribute to setting the stage for fungal ecological genomics as a whole. A deep understanding of biodiversity necessitates an accurate representation of the evolutionary history of species. The ability to discuss mechanisms of adaptation of yeast species to their environments is also limited by the relatively small number of phenotypic characteristics available for yeast descriptions. The major themes of interest to biogeography include the respective roles of dispersal and vicariance (allopatry) in speciation, glaciations, continental drift, and the major ecological regions of the earth.
