Table 2. Calculated values from the similarity index for the ascidian species in the study.
A | Santa Barbara Ascidian Populations | Total Markers | Monomorphic Markers | Total Bands Scored | Average Bands/Marker | Average bands/individual±SD |
Styela plicata | 233 | 29 (12.4%) | 8152 | 35 | 163±10 | |
Botryllus schlosseri | 328 | 24 (7.3%) | 11406 | 35 | 228±15 | |
Ciona intestinalis | 175 | 26 (14.9%) | 5890 | 34 | 118±7 | |
Botrylloides violaceus | 234 | 13 (5.6%) | 7422 | 32 | 148±11 | |
Aplidium californicum | 280 | 14 (5.0%) | 8269 | 30 | 165±14 | |
Styela clava | 261 | 24 (9.2%) | 7230 | 28 | 145±11 | |
Botrylloides diegensis | 389 | 3 (0.8%) | 10631 | 27 | 213±27 | |
Ascidia ceratodes | 353 | 17 (4.8%) | 7430 | 21 | 149±12 | |
Ascidia zara | 242 | 6 (2.5%) | 5156 | 21 | 103±16 | |
Ciona savignyi | 356 | 4 (1.1%) | 6413 | 18 | 128±23 |
Part A of the table is for the ascidian species from SBYH. The species are sorted according to the values in the Average Bands/Marker row. Species which have higher numbers of average bands per marker have a higher degree of similarity and therefore lower levels of polymorphism. Part B contains the information from the Ventura C. savignyi and C. intestinalis populations.
