“…To understand the correlation between ocean current transportation and genetic structure, we compared the genetic A map depicting sampling sites, distribution of lineages and intra-lineage haplotype groups and summer hydrographical conditions (drawn based on Yuan et al, 2017;Liu et al, 2021). Sampling sites are numerically coded from south to north: 1.…”

“…We divided the study region into the marginal seas in coastal China (Figure 1, Wei et al, 2011;Han et al, 2015;Xu et al, 2021), i.e., the South China Sea (SCS, sites 1-4), the East China Sea (ECS, sites 5-9), the South Yellow Sea (SYS, sites 10-12), the North Yellow Sea (NYS, site 13), and the Bohai Sea (BS, site 14). In summer, the SCS and ECS are affected by several northward and northeastward coastal currents, e.g., the South China Sea Coastal Currents, the Guangdong Coastal Current, and the Taiwan Strait Current (TSC, Liu et al, 2021). We used the Taiwan Strait Current to represent all the northward currents affecting the SCS and ECS.…”

“…The coasts of NYS, SYS, and BS are mainly affected by two coastal currents; the Yellow Sea Coastal Currents (YSCC, Liu et al, 2021), and the Subei Coastal Current (SBCC, Yuan et al, 2017). The YSCC merges with the Changjiang Diluted Water (CDW) and is deflected eastward (Figure 1, Yuan et al, 2017;Liu et al, 2021).…”

Currents shaped the genetic structure of Tridentiger barbatus (Günther 1861) along the Chinese coast

The modern coast of China is characterized by complicated hydrology, which might be a potential factor shaping genetic structure of marine organisms. Tridentiger barbatus is a widespread benthic goby in coastal China whose range expansion might depend on larval dispersal in its spawning season. We explored the genetic structure of T. barbatus and its interrelationships with coastal currents, planktonic larval duration, and Pleistocene climate fluctuations. Genealogies of Cytb, Rh, and RAG1 reveal two lineages in T. barbatus, namely the southern and northern lineages. The southern lineage is distributed through the South China Sea to the South Yellow Sea but is absent from the North Yellow Sea and Bohai Sea. The HYCOM average flow field indicates an eddy between the North and South Yellow Seas, which might cause larval retention and limit dispersal of the southern lineage into the North Yellow Sea and the Bohai Sea. The northern lineage is distributed through the South Yellow Sea to the Bohai Sea but is absent from the South China Sea and East China Sea. The distribution of the northern lineage fits the eastward deflection of the Yellow Sea Coastal Current at the boundary of the East China Sea and South Yellow Sea, which might limit southward larval dispersal of the northern lineage into the East China Sea. We also uncovered two Cytb haplotype groups within the southern lineage, namely groups A and B, whose distributions might be shaped by the northward Taiwan Strait Current. The coincidence between the genetic structure of T. barbatus and the coastal currents and eddies strongly implies significant roles of larval dispersal and current transportation in shaping the genetic structure of T. barbatus. In addition, significant isolation by distance is found in the southern lineage, which coincides with its short planktonic larval duration (20–30 days). The inference on divergence time suggests that the observed lineages and haplotype groups in T. barbatus originated in the Pleistocene glaciations. Therefore, the coastal currents, planktonic larval duration, and historical glacial isolation are proposed as important factors shaping the genetic structure of T. barbatus.

“…The KC and the Taiwan warm Current (TC) strongly influence the surface and subsurface waters of the ECS (e.g., Matsuzaki et al., 2016), respectively. The KC intrusion into the ECS is seasonally controlled by volume transport fluctuations (Z. Liu et al., 2021; Zhou, Song, Yuan, Wang, et al., 2018) in the transport of warm, highly saline waters from low to middle latitudes (D. Hu et al., 2015; D. Zhao et al., 2017; Zheng et al., 2016). The KC brings oxygen‐rich, warm, saline, and oligotrophic water to the ECS from the north equatorial Pacific region (Gallagher et al., 2015; Lee et al., 2001; Matsuzaki et al., 2016, 2019; Vats et al., 2020), while subsurface KC‐driven upwelling (Chen, 1996; Chen et al., 1995; K. K. Liu et al., 1992; Vats et al., 2020; Wu et al., 2008; Zhou, Song, Yuan, Cao, et al., 2018) brings nutrients and influences primary productivity.…”

The East China Sea (ECS) seasonally receives a high organic input due to the terrestrial organic matter influx, which is controlled by the East Asian Summer Monsoon (EASM), and the increased productivity driven by upwelling of the subsurface Kuroshio Current (KC). Changes in benthic foraminiferal assemblage composition in combination with paleoceanographic proxy data (CaCO3 (%), TOC (%), δ13Cpf, and δ18Obf) are used to reconstruct bottom water oxygenation and organic export flux variability over the last 400 kyr in the ECS. Multivariate analyses of benthic foraminiferal census data identified six biofacies characteristic of varying environmental conditions. These results suggest that enhanced EASM precipitation and KC upwelling directly influenced organic export flux and bottom water oxygen content in the ECS. The ECS bottom water was suboxic during Marine Isotope Stage (MIS) 11 to 8; suboxic to dysoxic between MIS 7 and 6, strongly dysoxic between mid‐MIS 5 and 4, and exhibited high variability between MIS 3 and 1. Spectral analysis of relative abundances of representative genera Quinqueloculina (oxic), Bulimina (suboxic), and Globobulimina (dysoxic) reveals a robust 23 kyr signal, which we attribute to precessionally‐paced changes in surface productivity and bottom water oxygenation related to KC variability over the past 400 kyr.
