Figure 1

Data availability matrix. Graphical representation of our concatenated alignment, showing the availability of sequence data. The color of column and row headers indicate the amount of data available for that column or row. Green indicates high data availability, red indicates low data availability and yellow/orange represents intermediate data availability. The matrix density is 34% in a locus × OTU context and 35% in a character × OTU context. Numbers in cells indicate length of sequence in alignment, which may include gaps and/or exclude ambiguously aligned regions. Figure generated with the gDAM software http://www.phycoweb.net.
