Multi-omics insights into seasonal dynamics and interaction networks underpinning planktonic community stability in a subtropical mussel aquaculture system
Marine planktonic communities drive ecosystem functions, but their dynamics in aquaculture systems remain poorly understood, limiting predictions of ecosystem stability under perturbations. Focusing on a subtropical mussel aquaculture system, a unique environment shaped by mussel-derived organic matter and filter-feeding activity, we conducted a 1.5-year time-series study integrating amplicon and metatranscriptomic sequencing to resolve compositional and functional dynamics of prokaryotic and phytoplankton communities. Distinct seasonal shifts in community composition, diversity and structure were observed, with prokaryotes exhibiting greater sensitivity to environmental fluctuation. We found that the compositional stability was strongly associated with ɑ-diversity in both communities. The reduced ɑ-diversity in summer coincided with destabilization, suggesting a vulnerability threshold under seasonal stress. Network analysis delineated temporal co-occurrence patterns of prokaryotic and phytoplankton communities, and uncovered intensified prokaryote-phytoplankton interactions from May to July, particularly between Flavobacteriales or Rhodobacterales and Dinophyta. Metatranscriptomic data highlighted a summer peak in gene expression related to phytoplankton‐derived molecule metabolism, labile substrate degradation, biosynthesis of phytohormones and vitamins, and flagellar assembly, indicating heightened metabolic cooperation between prokaryotic and phytoplankton communities. The specific dependence on phytoplankton might partly explained the low diversity and compositional stability in the prokaryotic community. Our findings emphasize the interplay of environmental fluctuations and functional interactions in shaping stability of the aquaculture ecosystem, providing a multi-omics framework for predicting planktonic responses to natural and anthropogenic perturbations, with implications for sustainable aquaculture management.
期刊介绍:
Water Research, along with its open access companion journal Water Research X, serves as a platform for publishing original research papers covering various aspects of the science and technology related to the anthropogenic water cycle, water quality, and its management worldwide. The audience targeted by the journal comprises biologists, chemical engineers, chemists, civil engineers, environmental engineers, limnologists, and microbiologists. The scope of the journal include:
•Treatment processes for water and wastewaters (municipal, agricultural, industrial, and on-site treatment), including resource recovery and residuals management;
•Urban hydrology including sewer systems, stormwater management, and green infrastructure;
•Drinking water treatment and distribution;
•Potable and non-potable water reuse;
•Sanitation, public health, and risk assessment;
•Anaerobic digestion, solid and hazardous waste management, including source characterization and the effects and control of leachates and gaseous emissions;
•Contaminants (chemical, microbial, anthropogenic particles such as nanoparticles or microplastics) and related water quality sensing, monitoring, fate, and assessment;
•Anthropogenic impacts on inland, tidal, coastal and urban waters, focusing on surface and ground waters, and point and non-point sources of pollution;
•Environmental restoration, linked to surface water, groundwater and groundwater remediation;
•Analysis of the interfaces between sediments and water, and between water and atmosphere, focusing specifically on anthropogenic impacts;
•Mathematical modelling, systems analysis, machine learning, and beneficial use of big data related to the anthropogenic water cycle;
•Socio-economic, policy, and regulations studies.
