Phylogeographic analysis of selected Hawaiian Rhodophyta. Statistical parsimony networks (95% connection limit) of four Hawaiian red algal taxa for which multiple collections were analyzed (a - Asparagopsis taxiformis, b - Ceramium dumosertum, c - Dasya iridescens, d - Amansia glomerata). The number of sequences for each haplotype is given in parentheses. Rectangles represent the hypothesized ancestral haplotype. Small circles indicate hypothetical intermediate haplotypes with single nucleotide changes. Haplotype size is proportional to frequency (relative for each taxon).
