“…Divergence values between 10% and 22% at CO1 are considered sufficient to identify separate bivalve species (Therriault et al 2002, Therriault et al 2004, Xue et al 2012, whereas values around of 0.6%-2.0% are typically observed at the intraspecific level (Baldwin et al 1996, Arnaud et al 2000, Xue et al 2012. Thus, the results of the current study are in accord with the hypothesis of Matsubara (2011) that P. generosa and P. japonica are distinct species.…”

Population Genetic Structure and Demographic History of Atrina pectinata Based on Mitochondrial DNA and Microsatellite Markers

The pen shell, Atrina pectinata, is one of the commercial bivalves in East Asia and thought to be recently affected by anthropogenic pressure (habitat destruction and/or fishing pressure). Information on its population genetic structure is crucial for the conservation of A. pectinata. Considering its long pelagic larval duration and iteroparity with high fecundity, the genetic structure for A. pectinata could be expected to be weak at a fine scale. However, the unusual oceanography in the coasts of China and Korea suggests potential for restricted dispersal of pelagic larvae and geographical differentiation. In addition, environmental changes associated with Pleistocene sea level fluctuations on the East China Sea continental shelf may also have strongly influenced historical population demography and genetic diversity of marine organisms. Here, partial sequences of the mitochondrial Cytochrome c oxidase subunit I (COI) gene and seven microsatellite loci were used to estimate population genetic structure and demographic history of seven samples from Northern China coast and one sample from North Korea coast. Despite high levels of genetic diversity within samples, there was no genetic differentiation among samples from Northern China coast and low but significant genetic differentiation between some of the Chinese samples and the North Korean sample. A late Pleistocene population expansion, probably after the Last Glacial Maximum, was also demonstrated for A. pectinata samples. No recent genetic bottleneck was detected in any of the eight samples. We concluded that both historical recolonization (through population range expansion and demographic expansion in the late Pleistocene) and current gene flow (through larval dispersal) were responsible for the weak level of genetic structure detected in A. pectinata.

“…populations in southern China. In our previous study, A. chinensis in southern China contained two lineages: the Beibu Gulf lineage and the northern South China Sea lineage (Xue et al, 2012). The Beibu Gulf is a semienclosed gulf with only one sea gate in the Qiongzhou Strait connected to the northern South China Sea.…”

“…The morphological and genetic characteristics of lineage 4 (the yellow form) match those of A. pectinata Linnaeus, which is restricted to Indonesia in the Indian Ocean (Huber, 2010;Lemer et al, 2016). Lineage 5 (the scabrous form) has been identified as A. chinensis through the investigation of morphological and genetic data (Xue et al, 2012). However, lineage 3 (the green form) was only reported as one morphological type of A. pectinata distributed in South China Sea (Yu et al, 2000(Yu et al, , 2004.…”

Phylogeographic studies contribute to addressing questions regarding the geographic patterns and evolutionary scenarios within and among species and also shed light on the taxonomic status of widely distributed species complexes. The pen shell Atrina pectinata species complex is a widely distributed and economically important bivalve in the northwestern Pacific. Previous phylogeographic studies have identified four genetically distinct cryptic species within the A. pectinata species complex along the coast of China, of which three cryptic species were distributed in the South China Sea. However, less attention has been given to their identification and delimitation. Herein, we report the phylogeography and taxonomic revision of the A. pectinata species complex in the South China Sea using DNA sequence data from mitochondrial cytochrome oxidase I (COI) and 16S ribosomal RNA (16S rRNA), and nuclear 28S ribosomal RNA (28S rRNA) gene markers. Using a combination of phylogenetic and DNA-based species delimitation analysis methods, we found strong support for four genetically valid species in the A. pectinata species complex and defined them as A. japonica, A. lischkeana, Atrina sp., and A. pectinata based on our results as well as on previous morphological and genetic studies. A demographic historical analysis showed that all three species in the South China Sea had populations that were relatively stable over time and then subjected to sudden expansion during the late Pleistocene (60,000–90,000 years ago). These results provide new insights into the systematics and evolution of the A. pectinata species complex and have important conservation and management implications.
