Patterns of genetic variation and geographical distribution. (A) Fine-scale geographic sampling at Fushan Botanical Garden in Taiwan. A total of 106 tree sites constituting 286 substrates were sampled in this region. Different colors represent different lineages, and filled circles denote sampled trees from which S. cerevisiae was not successfully isolated. (B) Genetic and geographic distance of isolate pairs identified in A. (C) Lack of correlation between genetic diversity θW at the synonymous site and geographical range across lineages. Diversity for lineages in which the geographical range is unavailable is indicated with dashed lines. (D) Frequency of asexual per sexual generations across lineages.
