A total of 27 haplotypes was defined by 23 variable nucleotide sites in the examined COI region. Pairwise population FST estimates and neighbor-joining tree inferred distinct genetic differentiation between the representative samples from the Pacific Ocean off the Eastern Hokkaido Island and the Sea of Japan, while others intermediated these two groups. AMOVA also showed a weak but significant differentiation among these three groups. The present results suggest a moderate population structure of hair crab, probably influenced by high gene flow between regional populations due to sea current dependent larval dispersal of this species.Springer New York2008-01engjournal articleAMhttp://hdl.handle.net/2115/33865http://www.springerlink.comhttps://doi.org/10.1007/s10126-007-9033-1179552931436-22281436-2236Marine Biotechnology1013948https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/33865/1/azuma.pdfapplication/pdf173.13 KB2008-01
