Oceanic currents drove population genetic connectivity of the brown alga Sargassum thunbergii in the north-west Pacific. Since S. horneri can grow rapidly under low temperatures (10°C –15°C) (Yoshida et al., 1998, 2004), the lower SST in the past might have only shortened its growth period or slowed its growth rate instead of causing its large-scale extinction.

The generation time, g (1 yr) and the mutation rate of cox3 (2.6–4.1%/Myr) (Uwai et al., 2009) were used to convert the output units into years. Previous studies have amplified the cox3 sequences for S. horneri populations ranging from Hokkaido, Japan (43°12′N) to Zhanjiang, China (20°53′N), including 54 sites in Japan (Uwai et al., 2009; Watanabe et al., 2019), 14 sites in Korea (Byeon et al., 2019), and 8 sites in China (Hu et al., 2011). In particular, non-buoyant seaweed and/or invertebrates could hitchhike on floating rafts formed by positive buoyant seaweeds (e.g., Sargassum, Durvillaea, Macrocystis), to colonize to newly available suitable habitats (Fraser et al., 2013; Boo et al., 2014; Guillemin et al., 2014; van Hees et al., 2019).

Under RCP 8.5, the more severe climate change scenario, by 2050 the highest habitat suitability was found along the coasts of Central-Pacific-Japan, and the southern and eastern coasts of Korea (Figure 2).

Environmental predictors used in species distribution models (MAXENT and GARP) of the seaweed Sargassum horneri. (2018). Sargassum is highly tolerant to environmental parameters such as desiccation, full sunlight and variations in salinity and temperature. (2018a). Under the assumption of neutrality, negative values represent population expansions, while positive values are considered a signature of recent bottlenecks (Excoffier and Lischer, 2010). During the LGM, the Yellow-Bohai Sea and East China Sea were reduced to Okinawa Trough, and Seto Inland Sea was terrestrial (Wang, 1999).

F., Ramos, E., Puente, A., and Juanes, J. Habitat. (2019) investigated how climatic-driven substitutions of two foundation species, Laminaria hyperborea (cold-affinity) and L. ochroleuca (warm-affinity), influenced community, trophic structure and functioning through processes associated with the cycling of organic matter (including biomass production, detritus flow, herbivory, and decomposition). Sargassum horneri is a habitat‐forming species in the Northwest Pacific and an important contributor to seaweed rafts. 107, 91–104. doi: 10.1007/s10531-019-01716-9, Cheang, C. C., Chu, K.

Apart from temperature, the monthly maximum and minimum average sea surface RCP scenarios also included simulations of salinity changes arising from alterations to the hydrological cycle. These large biotic rafts that can support an extensive pelagic habitat Sargassum Horneri tends to grow in dense, underwater canopies, that grow to be approximately 16 feet in length. The haplotype network revealed deep genetic splits among populations along the NW-Pacific (Figures 1A,B). doi: 10.1016/j.ecolmodel.2005.03.026, Posada, D., and Crandall, K. A. In our study, the divergence time between lineages ranged from 0.175 Mya to 0.266 Mya, much earlier than the LGM (0.018–0.020 Mya). (2019). The cold Oyashio current in this region may mitigate the rate of ocean warming and facilitate the growth of cold-water adapted species kelps (Saccharina, Alaria, Costaria) (Sudo et al., 2020) and warm-temperate species, such as Undaria pinnatifida (Sato et al., 2016) and Sargassum thunbergii (Li et al., 2017a). In Wakasa Bay it began to grow in early autumn through winter, becoming matured in Spring, when the sea water temperature was 11.6–15.2 °C (53–59 °F) in average. 24, 38–49. doi: 10.1016/j.aquabot.2014.08.004, Boo, G. H., Qiu, Y. X., Kim, J. Y., Ang, P. O., Bosch, S., De Clerck, O., et al. Our study area ranged from the Leizhou Peninsula in Guangzhou, China, to Sakhalin Bay in Russia (20–55°N, 109–150°E), thus covering the entire distribution of S. horneri in the NW-Pacific. Modeling effects of climate change and phase shifts on detrital production of a kelp bed. (2011). Although up to 17 local Sargassum species are distributed along the coast of the Yellow Sea and East China Sea, which are fixed to substrate (Lu and Tseng, 2004; Huang et al., 2017), S. horneri was identified as the only dominant species of drifting Sargassum in the Yellow Sea (Su L. et al., 2018). (2018). Most of these refugial populations, especially those at low latitude ranges, will likely become extinct under varying scenarios of climate change, resulting in the loss of this ancient genetic diversity (Assis et al., 2018a). 64, 526–540. Mar. Syst. Sargassum, also called gulfweed or sea holly, genus of about 150 species of brown algae (family Sargassaceae) generally attached to rocks along coasts in temperate regions or occurring as pelagic (free-floating) algae in the open sea. Projected climate changes threaten ancient refugia of kelp forests in the North Atlantic. (2007). We randomly selected 20% of the distribution records for training, reserving the remaining 80% for testing. Sci. To avoid overfitting the models to the occurrence records, we used the R package ‘MaxentVariableSelection’ (Jueterbock, 2015) to excluding a set of environmental variables with a relative contribution score < 5% or a correlation of > 0.7 with other variables (Supplementary Figures S1, S2, Table S4). 46, 183–189. Global Ecol. In all cases, the projected distribution area was restricted in space by a 17.5-km buffer zone from the coastline. The model with the lowest AIC was built based on the following three uncorrelated environmental variables (Supplementary Figure S1, S2, Table S4): mean primary productivity, LTA of maximum sea surface temperature (MaxSST) and LTA of minimum surface sea salinity (MinSSS) (Table 1). In this way, a total of 171 occurrence records of S. horneri in the NW-Pacific were finally compiled (Figure 1A, Supplementary Table S2). Mismatch distributions implemented in Arlequin 3.5 were also used to test demographic history (Rogers and Harpending, 1992). Mol. Such ancient refugia were often rich in unique phylogeographic lineages that are potentially essential for their adaptation to environmental change (Gurgel et al., 2020). Identifying climate refugia and areas that harbor high biodiversity is essential to operationalize and enforce marine conservation under ongoing climate change (Rilov et al., 2019).
