“…The typical seasonal dynamics of phytoplankton in ecosystems usually consist of two peaks: winter–spring and autumn. Algae autumnal blooms may be the primary biological factors that cause changes in the proportion of Cyanobacteria (Xie et al, 2021 ). A high proportion of Cyanobacteria in the guts of invasive silver carp ( Hypophthalmichthys molitrix ), indicating a connection to their green algae feeding habits in the Mississippi River Basin (Ye et al, 2014 ).…”

Gut microbiota is associated with host health and its environmental adaption, influenced by seasonal variation. Pomacea canaliculata is one of the world's 100 worst invasive alien species. Here, we used high‐throughput sequencing of the 16S rRNA gene to analyze the seasonal variation of gut microbiota of P. canaliculata . The results suggested that the predominant gut microbial phyla of P. canaliculata included Firmicutes and Proteobacteria, which helped digest plant food and accumulate energy. The gut microbiota of P. canaliculata in summer group showed the highest diversity, whereas the winter group possessed the lowest, probably due to the shortage of food resources of P. canaliculata in winter. Principal coordinate analysis analysis based on unweighted unifrac and weighted unifrac indicated that the composition of gut microbiota of P. canaliculata significantly varied across seasons. Bacteroidetes tended to be enriched in summer by linear discriminant analysis effect size analysis. Actinobacteria and Cyanobacteria were extremely abundant in autumn, while Fusobacteria and Cetobacterium enriched in winter. In conclusion, the structure of the gut microbiota of P. canaliculata was significantly different among seasons, which was beneficial to the environment adaptation and the digestion and metabolism of food during different periods.

“…Our results showed that algal blooms enhanced the co-occurrence relationships of the surrounding prokaryote communities, which may indicate that the interactions of those prokaryotes are signi cantly regulated by organic substrates. Previous research results also support this view but lack in-depth mining of network topology features (Xie et al 2021).…”

“…Some members of this group were reported to have algicidal activity (Lupette et al 2016;Yarimizu et al 2018). The previous studies focused more on the dominant groups' potential functions in the algal blooms or excavated the strong correlation between microbes and algae (Needham and Fuhrman 2016; Xie et al 2021;Zhang et al 2018). Although the speci c role of biotic interactions in prokaryotic community variations is unknown at this time, our nding revealed the crucial importance of the keystone taxa with low abundance during the algal blooms, which could be potential prokaryotic indicators to diagnose the ecosystem (Wang et al 2020a).…”

“…The cooccurrence network including the whole blooming progress revealed that some bacteria may play an important part in the formation or termination of the Noctiluca scintillans bloom (Zhou et al 2020). Another co-occurrence network analysis showed that the relative abundances of Litorimicrobium and Micromonas were substantially linked with the Skeletonema costatum bloom, and at each bloom stage, the relationships between microeukaryotes were more intricate than those between prokaryotes (Xie et al 2021). However, these network analyses rarely compare the topological characteristics of prokaryote cooccurrence networks at different stages of algae outbreaks, which usually re ects some ecological meanings (Yang et al 2017).…”

“…In addition to the co-occurrence network, assembly mechanisms are also signi cant factors in uencing the prokaryote community structure and composition (Stegen et al 2013). Some studies have made preliminary studies on the assembly mechanisms of the microbial community during the algal bloom (Shao et al 2020;Xie et al 2021). In this framework, stochastic and deterministic processes are important forces shaping microbial communities (Stegen et al 2013).…”

Algal blooms are severe ecological disasters in the marine environment, affecting the biogeochemical cycles substantially. It is critical to explore how the prokaryotic community responds to the dynamics of algal blooms in the marine environment. The shifts in prokaryotic communities during the algal blooms have been extensively investigated, while the interactions and assembly mechanisms of prokaryotic communities are still incompletely understood. We conducted nutrient addition cultivations for the brackish water from the Pearl River estuary to simulate the algal bloom process and monitored the prokaryotic community compositions over forty days. Results showed evident differences between blooming and after-bloom stages of prokaryotic communities in diversity and taxonomic compositions. Bacillus, Gimesiaceae, and Fibrobacteraceae were dominant before the cultivation. Mesoflavibacter, Rhodobacteraceae, and Acinetobacter were accumulated in the blooming stage. Acinetobacter, Comamonadaceae, and Gimesia were enriched in the after-blooming stage, while Mesoflavibacter, Rhodobacteraceae, and Acinetobacter were active during the whole blooming period. Co-occurrence networks analysis showed that prokaryotic interactions were predominantly driven by positive relationships that impacted the algal blooming fates. Rhodobacteraceae, Flavobacteriaceae, Winogradskyella, and Pseudomonas are the keystone groups of the prokaryotic communities in the blooming stage network, while Marinobacter, Thalassobaculum, Actinobacteria, Flavobacterium, and Rhodobacteraceae are the keystone groups of the after-bloom stage network. Functional prediction by FAPROTAX showed that dissimilatory nitrate reduction increased in the after-bloom stage. Our study revealed the dynamic of the prokaryotic communities and the characteristics of their co-occurrent profiles, which shed light on revealing the potential functions of prokaryotic behaviors during estuarine algal blooming events.
