Ryu, Jong-Seong Khim, and Ui-Wook Hwang (2012) Benthic fauna were collected from the
intertidal rocky shores of Dokdo Is., Republic of Korea. Four
qualitative surveys were performed at 9 stations between Aug. 2007 and
June 2008. In total, 98 marine invertebrate species in 57
families were identified during the study period. Of these 98
species, 21 (> 20%) were newly recorded on Dokdo Is. shores
including members of the Arthropoda (n
= 8), Mollusca (n
= 4), Annelida (n = 4),
Echinodermata (n = 2),
Porifera (n = 1), Cnidaria (n = 1), and Platyhelminthes (n = 1). By comparing related
references, we identified that the 98 species found at Dokdo exist in
mainland areas of both Korea and Japan. Topographical
descriptions and ecological comments are given for each of the major
species. Among the 7 phyla presented, the Mollusca and Arthropoda
predominated, accounting for > 70%-100% of the total taxa at each
station. A cluster analysis showed that the faunal composition
and distribution of invertebrates considered by habitation types
(attached, sessile, or mobile species) were possibly related to the
topographical characteristics of each station. Altogether, 403
species (of 10 phyla and 172 families) from a combination of the
present and previous studies indicate that the marine invertebrates
inhabiting the rocky bottoms in the Dokdo ecosystem show high and
dynamic biodiversity.
Key words: Dokdo, Marine Invertebrates,
Macrofauna, Far East, Biodiversity.
