Summary Microbial metacommunities normally comprise generalists and specialists. Uncovering the mechanisms underlying diversity patterns of these two sub‐communities is crucial for aquatic biodiversity maintenance. However, little known about ecological assembly processes co‐occurrence habitat specialists across large spatial scales in plateau lake sediments, particularly regarding their environmental adaptations. Here, we investigated sediment Tibetan lakes role stability metacommunity...
Different types of inlet water are expected to affect microbial communities lake ecosystems due changing environmental conditions and the dispersal species. However, knowledge effects changes in export assemblages on is limited, especially for glacier-fed lakes. Here, we collected samples from surface a its two fed streams Tibetan Plateau investigate importance glacial non-glacial as sources diversity bacterial communities. Results showed that stream was an important source microorganisms...
Background Bacteria play critical roles in marine nutrient cycles by incorporating and redistributing dissolved organic matter (DOM) inorganic nutrients the ocean. TonB-dependent transporter (TBDT) proteins allow Gram-negative bacteria to take up scarce resources from nutrient-limiting environments as well siderophores, heme, vitamin B12, recently identified carbohydrates. Thus, characterization of TBDT distribution functions is essential better understand contribution DOM assimilation its...
Geographic patterns of bacteria and microeukaryotes have attracted increasing attention. However, mechanisms underlying geographic in the community composition both microbial groups are still poorly resolved. In particular, knowledge whether bacterial communities microeukaryotic subject to same or different assembly is limited. this study, we investigated biogeographic 23 lakes on Tibetan Plateau quantified relative influence shaping communities. Results showed that water salinity was major...
Abstract Viruses are major players in the biosphere, yet little is known about their dynamics and life strategies alpine lakes, particularly those on Tibetan Plateau. We investigated microbial abundance, viral dynamics, 10 high‐altitude lakes found that they harbor high levels of active viruses. Salinity was identified as a crucial factor influencing well strategies. Lytic lysogenic productions moderate‐ high‐salinity were significantly higher than freshwater lakes. A trade‐off between...
Little is known about the functional capability of microbial communities in shallow-sea hydrothermal systems (water depth <200 m). This study analyzed two high-throughput pyrosequencing metagenomic datasets from vent and surface water system offshore NE Taiwan. exhibited distinct geochemical parameters. Metagenomic data revealed that were predominated by Epsilonproteobacteria (Nautiliales-like organisms) Gammaproteobacteria (Thiomicrospira-like organisms), respectively. A significant...
Cryoconite holes, water-filled pockets containing biological and mineralogical deposits that form on glacier surfaces, play important roles in mass balance, glacial geochemistry carbon cycling. The presence of cryoconite material decreases surface albedo accelerates loss, a problem particular importance the rapidly melting Tibetan Plateau. No studies have addressed microbial community composition holes their associated ecosystem processes glaciers. To further enhance our understanding these...
The free-living (FL) and particle-attached (PA) bacteria have different dispersal potentials ecological roles in aquatic ecosystems. However, our knowledge of their diversity regional biogeographic patterns high-altitude alpine lakes is limited. In this study, to investigate the geographic FL PA bacterial communities quantify relative influence environmental filtering limitation shaping communities, we collected surface water samples from 26 over 1000 kilometers on Tibetan Plateau. majority...
Alpine lakes, characterized by isolation, low temperatures, oligotrophic conditions, and intense ultraviolet radiation, remain a poorly explored ecosystem for RNA viruses. Here, we present the first comprehensive metatranscriptomic study of viruses in Lake Nam Co, high-altitude alkaline saline lake on Tibetan Plateau. Using combination sequence- structure-based homology searches, identified 742 virus species, including 383 novel genus-level groups 84 family-level exclusively found Co. These...
Abstract Understanding the diversity and functionality of carbon-fixing microorganisms in glacial ecosystems is crucial for elucidating carbon cycling processes extreme environments. This study investigates composition, diversity, metabolic potential Tibetan cryoconite. Through metagenomic sequencing, we identified 13 metagenome-assembled genomes (MAGs) spanning ten known three unclassified genera. DNA-stable isotope probing (DNA-SIP) experiments with 13C-labeled sodium bicarbonate (NaHCO3)...
Abstract Mountain glaciers are frequently assessed for their hydrological connectivity from to proglacial lakes. Ecological process on glacier surfaces and downstream ecosystems have often been investigated separately, but few studies focused the between different glacial habitats. Therefore, it remains a limited understanding of bacterial community assembly across habitats along continuum. In this study, we sampled catchment supraglacial snow, cryoconite holes, runoff, ice-marginal moraine...
It is widely accepted that bacterial community composition and diversity in remote alpine lakes are structured by environmental conditions such as nutrient status temperature. However, the mechanisms underlie structure remain unclear. We used 16S rRNA gene-based Illumina MiSeq sequencing to investigate complex ecological interactions between communities Kalakuli Lake, an glacial-fed lake Muztagh Ata of westernmost Tibetan Plateau. Our results indicated was dominated Actinobacteria...

Abstract Roseobacter clade bacteria are ubiquitous in marine environments and now thought to be significant contributors carbon sulfur cycling. However, only a few strains of roseobacters have been isolated from the deep-sea water column not thoroughly investigated. Here, we present complete genomes phylogentically closed related Thiobacimonas profunda JLT2016 Pelagibaca abyssi JLT2014 Southeastern Pacific. The genome sequences showed that two carry genes for versatile metabolisms with...
