摘要

海洋浮游生物群落驱动生态系统功能,但它们在水产养殖系统中的动态仍然知之甚少,限制了对扰动下生态系统稳定性的预测。本研究以亚热带贻贝养殖系统为研究对象,结合扩增子测序和亚转录组测序,对该系统进行了1.5年的时间序列研究,分析了原核生物和浮游植物群落的组成和功能动态。在群落组成、多样性和结构上存在明显的季节变化,原核生物对环境波动表现出更大的敏感性。结果表明,两种群落的成分稳定性与植物的多样性密切相关。夏季降水中,降水多样性的减少与降水的不稳定性一致,表明在季节性压力下存在脆弱性阈值。网络分析揭示了原核生物群落与浮游植物群落的时间共生模式,并揭示了5 - 7月间原核生物与浮游植物的相互作用增强,特别是黄杆菌门或红杆菌门与Dinophyta门之间的相互作用。亚转录组学数据强调,夏季与浮游植物衍生的分子代谢、不稳定底物降解、植物激素和维生素的生物合成以及鞭毛组装相关的基因表达高峰,表明原核生物和浮游植物群落之间的代谢合作增强。对浮游植物的特殊依赖可能是原核生物群落多样性和组成稳定性较低的部分原因。我们的研究结果强调了环境波动和功能相互作用在塑造水产养殖生态系统稳定性中的相互作用,为预测浮游生物对自然和人为扰动的响应提供了一个多组学框架,对可持续水产养殖管理具有重要意义。

Multi-omics insights into seasonal dynamics and interaction networks underpinning planktonic community stability in a subtropical mussel aquaculture system

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.
