西北太平洋海岸带大弹涂鱼复合体的隐存种与进化历史
CRYPTIC SPECIES AND EVOLUTIONARY HISTORY OFBOLEOPHTHALMUS PECTINIROSTRIS COMPLEX ALONG THE NORTHWESTERN PACIFIC COAST
摘要
Abstract
The species range ofBoleophthalmus pectinirostrissensu lato includes two disjunctive areas, i.e., East Asia and Strait of Malacca in Malaysia along the northwestern Pacific coast. However, the species status of Malaysian populations remains disputed. MitochondrialND5 gene (718 bp) and nuclearRag1 gene (1395 bp) were used to reconstruct phyloge-netic relationships among Boleophthalmus pectinirostris fishes by sampling 45 specimens from 11 locations in the north-western Pacific. The results showed thatBoleophthalmus pectinirostrisfishes could be divided into two major mono-phyletic groups, i.e., East Asian lineage and Malaysian lineage, and which together formed the sister-group relationship. Species delineation using the analyses of GMYC and *Beast species tree supports that East Asian lineage and Malasian lineage ofBoleophthalmus pectinirostrissensu lato should be placed into two different species. Molecular dating revealed that the divergence time between East Asian lineage and Malaysian lineage ofBoleophthalmus pectinirostrissensu lato was 2.73 Ma. We concluded thatBoleophthalmus pectinirostrissensu lato was a complex, including two species. The East Asian populations isBoleophthalmus pectinirostris sensu stricto,and the Malaysian populations is a cryptic species (Bo-leophthalmus sp.). Our findings suggested that species split betweenBoleophthalmus pectinirostris sensu strictoandBo-leophthalmus sp. was attributed to geographical isolation during lowing sea levels of ice ages and the barrier of gene flow induced by ocean currents during interglacial period in the late Pliocene.关键词
