Temporal Changes in Nudibranch Composition at a Coastal Site off Penghu (the Pescadores) in the Taiwan Strait
Yeng Su, Li-Jin Huang, Yen-Wei Chang, and Hin-Kiu Mok (2009) In total, 74 nominal species and 7 possible new species of sea slugs were recorded at a site off the coast of Wai-an in Penghu (the Pescadores) in the Taiwan Strait from 20 survey dives (including 17 monthly surveys). The Chromodorididae and Phyllidiidae were the 2 most-speciose families. The mean number of species sighted per monthly survey was 12. The increase in new species recorded reached a plateau at the 18th survey. The number of families recorded per survey ranged 2-9. High nudibranch species diversity is a site-specific attribute of Wai-an. Except for 1 survey, no species at this site were considered dominant in terms of the abundance of individuals. Similarities in species composition for pair-wise monthly samples were low. No obvious trends in temporal changes in the number of species or species composition were noted.
