Figure 2

Unrooted network of 72 unique rDNA sequence types. Sequence type network constructed from the concatenated ITS and 28S (C2-D2 region) alignment using statistical parsimony. Numbers with the prefix "S" indicate sequence type number [compare with Additional Table 1] and small black dots denote hypothetical (not observed) intermediate sequence types. The size of the white circles indicates the relative frequency of the sequence type in the data set. Large clades are color coded according to their main geographic distribution. Blue: Northwest Pacific; green: Southern Pacific; orange: Philippines; red: Indian Ocean.
