Abstract Background Microorganisms in rivers and lakes are essential for nutrient recycling aquatic ecosystems. Understanding the ecological processes shaping microbial communities is of crucial importance ecology biogeography. However, diversity microorganisms forces that control this poorly understood. This particularly true within framework river-lake continuum arid regions. Results Using a whole catchment-sampling effort, we explored biogeographical patterns mechanisms community (bacteria archaea) assembly catchment largest inland once freshwater lake (Lake Bosten) China. Water samples from headstream tributaries, mainstream River Kaidu to downstream Lake Bosten were characterized using amplicon sequencing 16S rRNA genes. Higher α-diversity was found tributaries compared with Bosten. And composition also significantly different between its connected river habitats. Canonical correspondence analysis demonstrated salinity total suspended solids most important environmental factors variations. Overall, pure spatial explained 13.7 5.6% variation, respectively, while 32.0% variation by combined variables. These observations suggested spatially structured variations mainly shaped biogeography region. Both deterministic stochastic influenced habitats, pattern pronounced microbiome habitat. Co-occurrence network revealed more abundant complicated correlations among frequently occurred taxa habitat habitat, implying multispecies interactions (e.g., competition) structures. Conclusions Our findings demonstrate an succession along across basin China, highlight effects on regional β -diversity species local assembly.

Disentangling the biogeographic patterns of rare and abundant microbes is essential in order to understand generation maintenance microbial diversity with respect functions they provide. However, little known about ecological assembly processes environmental adaptation across large spatial-scale wetlands. Using Illumina sequencing multiple statistical analyses, we characterized taxonomic phylogenetic bacteria fungi Qinghai-Tibet Plateau wetland soils. Abundant taxa exhibited broader thresholds stronger signals for traits than ones. By contrast, showed higher sensitivity changes closer clustering The null model analysis revealed that dispersal limitation belonging stochastic process dominated community assemblies bacteria, fungi, while variable selection deterministic governed bacteria.

Abstract Cyanobacteria harmful algal blooms (cHABs) are increasingly becoming an emerging threat to aquatic life, ecotourism, and certain real estate investments. Their spontaneous yet sporadic occurrence has made mitigation measures a cumbersome task; moreover, current trends regarding anthropogenic activities, especially in agriculture industry portend further undesirable events. Apart from the aesthetic degeneration they create their respective habitats, equally capable of secreting toxins, which altogether present grave environmental medical consequences. In this paper, we gave update on factors that influence cHABs, cyanotoxin exposure routes, public health implications, impacts fish, pets, livestock. We discussed social economic impacts, risk assessment, management problems for cHABs and, thereafter, assessed extant approaches including prevention, control, proliferation cyanobacterial blooms. light this, suggest more intensified research should be directed standardization procedures analysis. Also, provision standardized reference material quantification cyanotoxins is vital routine monitoring as well development strong situ sensors quantifying detecting HABs cells toxins waterbodies prevent adverse cHABs. investigations into natural environmentally friendly approach cyanobacteria necessary appropriate deployment artificial intelligence required.

ABSTRACT Our ability to describe the highly diverse pool of low abundance populations present in natural microbial communities is increasing at an unprecedented pace. Yet we currently lack integrative view key taxa, functions and metabolic activity which make-up this communal pool, usually referred as ‘rare biosphere’, across domains life. In context, review examines rare biosphere its broader sense, providing historical perspective on representative studies enabled bridge concept from macroecology ecology. It then addresses our current knowledge prokaryotic biosphere, covers emerging insights into ecology, taxonomy evolution microeukaryotic, viral host-associated communities. We also recent methodological advances provide a synthetic overview how fits different conceptual models used explain community assembly mechanisms, composition function.

Estuarine salt marshes are highly productive ecosystems subjected to regular disturbances by hydrodynamic exchange. However, little is known about how distinct assembly processes and co-occurrence of taxa influence the structure abundant rare bacterial biospheres in these soil systems. This study aims at unravelling intricacies studying a typical estuarine marsh located Hangzhou Bay, China. Our provides important pieces evidence on diverse distribution biospheres. We show that few central nodes species co-occurrence, potentially playing roles as keystone system. In addition, we highlight dynamic interplay structuring two subcommunities.

In deep drinking water reservoir ecosystems, the dynamics and interactions of community compositions phytoplankton eukaryotes during mixing periods are still unclear. Here, morphological characteristics combined with high-throughput DNA sequencing (HTS) were used to investigate variations eukaryotic in a large canyon-shaped, stratified located at Heihe River Shaanxi Province for three months. The results showed that Bacillariophyta Chlorophyta dominant taxa community, accounting more than 97% total abundance, which mainly consisted Melosira sp., Cyclotella Chlorella respectively. Illumina Miseq suggested biodiversity increased over time species distribution was even. Arthropoda (6.63% 79.19%), Ochrophyta (5.60% 35.16%), Ciliophora (1.81% 10.93%) Cryptomonadales (0.25% 11.48%) keystone common, contributing 50% community. Cryptomycota as unique fungus observed possess significant synchronization algal density, reaching maximum 10.70% December (when density distinctly decreased) suggesting it might affect growth algae through parasitism. Co-occurrence network patterns revealed complicated diverse between phytoplankton, respond dynamic structure although there be antagonistic or mutualistic them. Redundancy analysis (RDA) environmental variables collectively explained 96.7% variance 96.3% microorganisms, indicating temporal microorganisms significantly affected by conditions. This study shows potential exist microorganism communities, andcould improve our understanding ecological roles changing aquatic ecosystems. However, long-term investigations necessary order obtain comprehensive understandings their associations.

Abstract Background Mangrove ecosystems are vulnerable due to the exotic Spartina alterniflora ( S. ) invasion in China. However, little is known about mangrove sediment microbial community assembly processes and interactions under invasion. Here, we investigated co-occurrence networks of archaeal bacterial communities along coastlines Fujian province, southeast Results Assembly overall was driven predominantly by stochastic processes, relative role stochasticity stronger for bacteria than archaea. Co-occurrence network analyses showed that structure more complex The keystone taxa often had low abundances (conditionally rare taxa), suggesting abundance may significantly contribute stability. Moreover, increased drift process (part processes), improved complexity stability, but decreased stability bacteria. This could be attributed influenced diversity dispersal ability, as well soil environmental conditions. Conclusions study fills a gap patterns both archaea ecosystem Thereby provides new insights plant on biogeographic distribution patterns.
