Fig. 4From: Distribution patterns of haplotypes for symbionts from Umbilicaria esculenta and U. muehlenbergii reflect the importance of reproductive strategy in shaping population genetic structureThe haplotype network of photobionts. The result was calculated by TCS (95 % parsimony probability, the connection limit of 20 mutational steps and gaps treated as the fifth character state) and decorated using Adobe Illustrator CS4.0. Each circle represents a certain photobiont haplotype, and the size of the pie chart is proportional to the numbers of the samples. Different color of pie charts stands for different lichen species; and in each pie chart, the side surface with different color marks for the collection locations, which are abbreviated as two capitals with the same means as those in Fig. 1 Back to article page
