“…3). These results support the idea that macroalgae surfaces are highly selective, and physiological and biochemical properties (e.g., polysaccharides, hydrogen peroxide, and polyphenols) of different macroalgal groups could provide some explanation for the specificity of macroalgae-microbiota interactions (van der Loos et al 2019, Paix et al 2021b.…”

“…Macroalgal surfaces are the primary physiological and ecological interface with the environment, involved in the exchange of nutrients and chemical signals (Saha and Weinberger 2019). As a marine holobiont, macroalgae are capable of manipulating the composition of associated microbiota through chemical defenses (e.g., proline, dimethylsulphoniopropionate [DMSP], and fucoxanthin; Paix et al 2021a) and/or chemoattractants released at their surface (Kessler et al 2018, van der Loos et al 2019. In turn, microbial communities play a crucial role in macroalgal growth (Marshall et al 2006, Singh and Reddy 2014, Wichard 2022, morphogenesis (Spoerner et al 2012, Tapia et al 2016, protection against pathogens (Vallet et al 2018), and adaptation/acclimation to environmental stress (Paix et al 2021b, Ghaderiardakani et al 2022.…”

“…However, some microbes cause tissue bleaching (Zozaya-Valdés et al 2016) and/or tissue degradation (Egan et al 2013). Although most of the studies on host-microbial interactions are limited to economically importance species (e.g., domesticated plants; Cordovez et al 2019) and some specific model systems (e.g., mice and coral; Cornwell and Hernandez 2021), there has been an increase in studies demonstrating the diverse communities of hostassociated microbiota in macroalgae (van der Loos et al 2019).…”

“…In temperate waters, Sargassum species that maintain in the winter months a relatively high biomass, including marine animals (e.g., fish and invertebrates), are thought to have an especially high conservation value. Apart from the important ecological benefits, Sargassum have great economic value, and could be processed for food, fertilizers, and cosmetics (Liu et al 2021). However, anthropogenic global warming and habitat loss have jointly led to shifts in species distributions.…”

Host-related microbiota are critically important for the adaptation/acclimation of hosts to changing environments, but how environmental factors and host characteristics shape the microbial communities remains largely unknown. We investigated the effects of temperature on habitat-forming macroalgae and their associated bacterial communities. Three Sargassum species (S. horneri, S. fusiforme, and S. thunbergii) and seawater samples were sampled in Gouqi Island, China, and these macroalgal samples were incubated at different temperatures (10, 20, and 27°C) for 7 d. Bacterial communities were identified from the 16S rRNA gene V3-V4 regions. The algae-associated bacterial communities of the field samples were significantly different from seawater, implying host specificity. During laboratory incubation, decreased physiological status (photosynthetic rate and oxidative stress response) was detected for all the species at 10°C, especially with regard to S. horneri and S. fusiforme. For each host, associated bacterial communities at 20 and 27°C clustered closely, and these were separated from samples at 10°C based on constrained PCoA analyses. Permutational multivariate analysis of variance revealed that algae-associated bacterial communities were more affected by host species (23.3%) than by temperature (2.48%) during laboratory incubation. The changes in bacterial community composition may be influenced by algae metabolites, which should be tested in a future study. These results further contribute to our understanding of algal microbiome changes in response to environmental changes.

Coastal artificial structures on the former mudflats provide available habitats for the rocky intertidal species which can establish new populations in these emerging habitats over their former distribution range limits. As a former southern species, the oyster Crassostrea sikamea has become a pioneer and rapidly invaded the artificial shorelines in northern China. We used a seascape genomics approach to investigate the population structure and genetic sources of C. sikamea on the coastal artificial structures, which is crucial for understanding the genetic mechanisms driving species distribution range expansion and invasion pathway of intertidal species. Five C. sikamea populations, including two artificial substrate populations (WGZ and ZAP), one oyster reef population (LS), and two natural rocky shore populations (ZS and XM), were measured using single nucleotide polymorphism (SNPs) obtained from double digest restriction‐site associated DNA sequencing (ddRAD‐Seq). Redundancy analyses (RDA) were implemented for investigating the relationship between local temperature variables and the temperature adaptability of C. sikamea. Genetic diversity, direction and strength of gene flow, and population structure all revealed that the LS and ZS populations were the genetic sources for the oyster populations on the emerging northern coastal artificial structures. Results of RDA showed that there were different adaptive potentials for northern and southern populations to local temperature variables and the oyster reef population which frequently suffers from heat stress owned high heat adaptability. The ZS population as a genetic source nearby the Yangtze River estuary provided mass larvae for the northern populations, and the other genetic source, the heat‐tolerant LS population, in the oyster reef played an important role in the post‐settlement success by providing preadapted genotypes. These results highlight the importance of multiple sources with divergent adaptative capabilities for biological invasion, and also emphasize the importance of the oyster reef in coastal biodiversity and conservation.
