Marine microbial eukaryotes are ubiquitous, comprised of phylogenetically diverse groups and play key roles in food webs global biogeochemical cycling. However, their vertical distribution the deep sea has received little attention. In this study, we investigated composition diversity both 0.2-3 μm >3 size fractions from surface to hadal zone (8727 m) Mariana Trench using Illumina MiSeq sequencing for 18S rDNA. The eukaryotic community structure differed substantially across depths....
Abstract Deciphering the spatiotemporal dynamics and relative competitive advantages of trophic functional traits under multiple stressors has been a long-standing challenge. Here, we integrated core taxa identification with robust simulation modeling to reveal key environmental factors influencing three groups (autotroph, heterotroph, mixotroph), particular focus on mixoplankton. Temporally, mixoplankton exhibited higher proportion in spring winter contrast heterotrophs more uniform spatial...
Phytoplankton are diverse and abundant as primary producers in the ocean, with diversity community compositions varying spatially. How fundamental processes (e.g., selection, dispersal, drift) regulate their global biogeography remains to be comprehensively explored.
Nutrient pollution in the coastal environment has been accelerated by progressively intensifying aquaculture activities. Excessive nutrients can lead to eutrophication with serious economic and ecological consequences. In this study, we studied planktonic microbial community over a year understand impact on water quality function. We observed increased total inorganic nitrogen concentrations active fish farms favor diverse Alpha- Gammaproteobacteria. Bacterial alpha diversity was positively...
Abstract Aim In microbial biogeography, it is crucial to link spatial patterns with underlying drivers in natural ecosystems. Bacterial communities driving key biogeochemical processes coastal zones, which are important interfaces between terrestrial and marine ecosystems, affected by perturbations due both anthropogenic factors. However, the assembly of bacterioplankton communities, either free‐living (FL) or particle‐associated, ecosystems still poorly understood. Location Coastal South...
Cold seeps are biological oases of the deep sea fueled by methane, sulfates, nitrates, and other inorganic sources energy. Chemolithoautotrophic bacteria archaea dominate seep sediment, their diversity biogeochemical functions well established. Fungi likewise diverse, metabolically versatile, known for ability to capture oxidize methane. Still, no study has ever explored functional role mycobiota in cold biome. To assess complex fungi fill gaps, we performed network analysis on 147 samples...
Picoeukaryotes (<2–3 μm) perform key roles for the functioning of marine ecosystems, but little is known regarding composition and diversity picoeukaryotes in aquaculture areas. In this study, Illumina MiSeq platform was used sequencing V4 variable region within 18S rDNA gene to analyse genetic relative abundance picoeukaryotic communities Qinhuangdao scallop cultivation area Bohai Sea. The community dominated by three super groups, alveolates (54%), stramenopiles (41%) chlorophytes (3%),...
Abstract Background Nutrient stoichiometry of phytoplankton frequently changes with aquatic ambient nutrient concentrations, which is mainly influenced by anthropogenic water treatment and the ecosystem dynamics. Consequently, can markedly alter metabolism growth zooplankton. However, effects nutrient-imbalanced prey on interplay between zooplankton their gut microbiota remain unknown. Using metatranscriptome, a 16 s rRNA amplicon-based neutral community model (NCM) experimental validation,...
Abstract Unicellular cyanobacterial diazotrophs (UCDs) are important nitrogen (N) fixers in marine ecosystems. However, the top‐down control on UCDs is poorly understood, especially for microzooplankton grazing that often considered to be dominant loss factor primary production oligotrophic oceans. In this study, we investigated growth and rates of major UCD taxa (UCYN‐A1, UCYN‐A2/3/4, UCYN‐B, UCYN‐C) South China Sea Luzon Strait using a combination dilution experiments quantitative PCR. All...
Summary Mesoscale eddies are ubiquitous oceanographic features that influence the metabolism and community structure of Synechococcus . However, metabolic adaptations this genus to eddy‐associated environmental changes have rarely been studied. We recovered two high‐quality metagenome‐assembled genomes (MAGs) from in South China Sea compared their variations using metatranscriptomic samples obtained at same time. The MAGs (syn‐bin1 syn‐bin2) affiliated with marine subclusters 5.2 (S5.2) 5.3...
Many deep-sea invertebrates largely depend on chemoautotrophic symbionts for energy and nutrition, some of them have reduced functional digestive tracts. By contrast, mussels a complete system although in their gills play vital roles nutrient supply. This remains can utilise available resources, but the associations among gut microbiomes these remain unknown. Specifically, how microbiome reacts to environmental change is unclear.The meta-pathway analysis showed nutritional metabolic mussel...
The size structure of microeukaryotic plankton communities exerts a fundamental control on marine ecosystem functions, such as food web dynamics and element flows. global expansion nitrogen (N) phosphorus (P) nutrient pollutants into estuaries coastal waters is causing public health environmental concerns associated with activities. In the context eutrophication, understanding how biotic activities responds to anthropogenic inputs vital evaluate future fate ecosystems. Here, we conducted...
Abstract Effects of nutrient‐imbalanced diet on the growth and fitness zooplankton were widely reported as key issues to aquatic ecology. However, little is known about molecular mechanisms driving physiological changes under nutrient stress. In this study, we investigated transcriptomic response Daphnia magna when exposed nitrogen (N)‐limited or phosphorus (P)‐limited algal ( Chlamydomonas reinhardtii ) compared regular algae (N P saturated). D. showed higher ingestion rates overexpression...
Zooplankton grazers, like copepods, can feed on toxic microalgae and live normally. We hypothesize that gut microbial communities (GMCs) may contribute to the detoxification of host by changing their compositions recruiting more beneficial bacteria. Here, we measured physiological responses two copepod species ( Acartia sp. Paracalanus sp.) fed with Alexandrium tamarense ) non-toxic andersonii dinoflagellates, respectively. Both copepods maintained consistently high survival rates but...
