“…Previous studies have suggested that aquatic and benthic signals from the Changjiang River Estuary can be observed in the Jiangsu coastal waters. For example, Li et al (2021) suggested that newly colonized Littorina brevicula on the Jiangsu Coast south of ~33.5°N originated from natural rock‐dwelling populations in the Changjiang River Estuary, indicating that the transport of larvae from the estuarine region played a key role in this colonization. It is notable that the plume transport along the Jiangsu Coast occurs at all water depths.…”

The distribution of the early life stages of Larimichthys polyactis indicates the availability of suitable spawning and nursing grounds and enables a better understanding of the distribution of its geographic subpopulations and isolation. Large‐scale quantitative ichthyoplankton surveys of L. polyactis were performed from March to July 2018, and a numerical hydrodynamic model was applied to explore the spatiotemporal distribution and habitats of L. polyactis early life stages adjacent to the Changjiang River Estuary. Two distinct early life stage distribution patterns were found. One occurred during March and April in the deep waters seaward of the Changjiang River bottom plume front, to the east and southeast of the Changjiang River Estuary. The other occurred in May and June throughout the entire water column in coastal waters to the east and north of the Changjiang River Estuary. Rising seasonal temperatures, and the local dynamic processes such as the Changjiang River plume, determined the transitions between the two distribution patterns. A potential fish larval migration route from the southern deep shelf waters to the northern coastal waters within the motor‐trawl prohibition line was suggested. This study contributes to our understanding of the mixture of habitats used by the two L. polyactis subpopulations in the southern Yellow Sea and the East China Sea.

“…The abundant Yangtze River‐derived mud deposit on the inner shelf, combined with contribution from other rivers, has created a large delta plain (3 × 10 4 km 2 ) and a muddy tidal flat along the coastline from the Northern Jiangsu Province (~35° N) to the Southern Zhejiang Province (30° N) over about 500 km wide (Zhu et al., 2008). A few studies have revealed the Yangtze River Estuary as a physical barrier for several intertidal molluscs (Dong et al., 2012; Li et al., 2021; Ni et al., 2015; Wang et al., 2015) or macroalga (Cheang et al., 2010) due to the unusual substrate and/or the effect of freshwater discharge. As Z. japonica could tolerate short‐term exposure to zero salinity in situ (Kaldy & Shafer, 2013; Shafer et al., 2011) and survive in very muddy bottom (Zhang, Lin, et al., 2019), neither the salinity nor the substrate conditions seem to have limited the survival of Z. japonica in the Yangtze River Estuary.…”

AimThe seagrass Zostera japonica is a dramatically declined endemic species in the Northwestern Pacific from the (sub)tropical to temperate areas, however, it is also an introduced species along the Pacific coast of North America from British Columbia to northern California. Understanding the population's genetic patterns can inform the conservation and management of this species.LocationNorth Pacific.MethodsWe used sequences of the nuclear rDNA internal transcribed spacer (ITS) and chloroplast trnK intron maturase (matK), and 24 microsatellite loci to survey 34 native and nonnative populations (>1000 individuals) of Z. japonica throughout the entire biogeographic range. We analysed the phylogeographic relationship, population genetic structure and genetic diversity of all populations and inferred possible origins and invasion pathways of the nonnative ones.ResultsAll markers revealed a surprising and significant deep divergence between northern and southern populations of Z. japonica in the native region separated by a well‐established biogeographical boundary. A secondary contact zone was found along the coasts of South Korea and Japan. Nonnative populations were found to originate from the central Pacific coast of Japan with multiple introductions from at least two different source populations, and secondary spread was likely aided by waterfowl.Main ConclusionsThe divergence of the two distinct clades was likely due to the combined effects of historical isolation, adaptation to distinct environments and a contemporary physical barrier created by the Yangtze River, and the warm northward Kuroshio Current led to secondary contact after glacial separation. Existing exchanges among the nonnative populations indicate the potential for persistence and further expansion. This study not only helps to understand the underlying evolutionary potential of a widespread seagrass species following global climate change but also provides valuable insights for conservation and restoration.
