Plankton metabarcoding is increasingly implemented in marine ecosystem assessments and more cost-efficient less time-consuming than monitoring based on microscopy (morphological). 18S rRNA gene the most widely used marker for groups’ species’ detection classification within eukaryotic microorganisms. These datasets have commonly relied acquisition of organismal abundances directly from number DNA sequences (i.e. reads). Besides inherent technical biases metabarcoding, largely varying copy...
The procedures and methodologies employed to study microbial eukaryotic plankton have been thoroughly discussed. Two main schools exist—one insisting on classic microscopy the other supporting modern high-throughput sequencing (DNA metabarcoding). However, few studies attempted combine both these approaches; most implement one method while ignoring other. This work aims contribute this discussion examine advantages disadvantages of each methodology by comparing marine community results from...
Abstract Mixotrophs combine photosynthesis with phagotrophy to cover their demands in energy and essential nutrients. This gives them a competitive advantage under oligotropihc conditions, where nutrients bacteria concentrations are low. As the for mixotroph depends on light, competition between mixo- heterotrophic bacterivores should be regulated by light. To test this hypothesis, we incubated natural plankton from ultra-oligotrophic Eastern Mediterranean set of mesocosms maintained at 4...
The European Marine Omics Biodiversity Observation Network (EMO BON) is an initiative of the Biological Resource Centre (EMBRC) to establish a persistent genomic observatory among designated coastal marine sites, sharing same protocols for sampling and data curation. Environmental samples are collected from water column, at some soft sediments hard substrates (Autonomous Reef Monitoring Structures - ARMS), together with set mandatory discretionary metadata (including Essential Ocean...
Molecular methods such as DNA/eDNA metabarcoding have emerged useful tools to document the biodiversity of complex communities over large spatio-temporal scales. We established an international Marine Biodiversity Observation Network (ARMS-MBON) combining standardised sampling using autonomous reef monitoring structures (ARMS) with for genetic marine hard-bottom benthic communities. Here, we present data our first campaign comprising 56 ARMS units deployed in 2018-2019 and retrieved...
Continuing the international efforts of ARMS Marine Biodiversity Observation Network (ARMS-MBON), we present data from second sampling campaign, coming 56 Autonomous Reef Monitoring Structures (ARMS) deployed in 2020 and 2021 along European coasts under Omics (EMO BON). The set includes information on locations conditions, sample archiving, quality reports collected samples. Data metadata are openly accessible can be downloaded associated GitHub repository. Sequence accessed via Nucleotide...

The effect of episodicity Saharan dust deposition on the pelagic microbial food web was studied in oligotrophic Eastern Mediterranean by means a mesocosm experiment May 2014. Two different treatments triplicates (addition natural single-strong pulse or three smaller consecutive doses same total quantity), and unamended controls were employed; chemical biological parameters measured during 10-day experiment. Temporal changes primary (PP) bacterial (BP) production, chlorophyll (Chla)...
Marine ecosystems, ranging from coastal seas and wetlands to the open ocean, accommodate a wealth of biological diversity small microorganisms large mammals. This biodiversity its associated ecosystem function occurs across complex spatial temporal scales is not yet fully understood. Given wide range external pressures on marine environment, this knowledge crucial for enabling effective conservation measures defining limits sustainable use. The development application omics-based approaches...
The release of silver nanoparticles (AgNPs) is expected to rise in the near future, with possible negative effects on aquatic life and enhancement microbial resistance against AgNPs.
Abstract A new mesocosm setup containing both water column and sediment suitable for benthic‐pelagic coupling experiments is described. The presence of a large volume (>1.5 m 3 ) with sufficient depth (4 m) on the top sediment, combined bottom (30 cm height, 80 L volume) offers opportunities scale. experimental includes bag, securing ring cap top, container bottom, traps, an autonomous sampling system at specific depths, newly developed sampler collecting samples without disturbing...

Omic BON is a thematic Biodiversity Observation Network under the Group on Earth Observations (GEO BON), focused coordinating observation of biomolecules in organisms and environment. Our founding partners include representatives from national, regional, global observing systems; standards organizations; data sample management infrastructures. By strategies, methods, flows, will facilitate co-creation omics meta-observatory to generate actionable knowledge. Here, we present key elements...
Marine microbial eukaryotes play crucial roles in water-column ecosystems; however, there are regional gaps the investigation of natural eukaryote communities, and uncertainties concerning their distribution persevere. This study combined 18S rRNA metabarcoding, biomass measurements statistical analyses multiple environmental variables to examine planktonic at different sites water layers ultra-oligotrophic Eastern Mediterranean Sea (Western Levantine Basin). Our results showed that...
Abstract. The extracellular concentration of H2O2 in surface aquatic environments is controlled by a balance between photochemical production and the microbial synthesis catalase peroxidase enzymes to remove from solution. In any kind incubation experiment, formation rates equilibrium concentrations reactive oxygen species (ROSs) such as may be sensitive both experiment design, particularly regulation incident light, abundance different groups, cellular catalase–peroxidase enzyme differ...
Excessive primary productivity due to nutrient inputs is a potential problem in coastal areas when resulting high organic matter sedimentation rates. Microphytobenthos and heterotrophic bacteria are two components of the benthic ecosystem that contribute cycling decomposition matter. In this context, effects addition associated situ produced on microphytobenthos community composition bacterial viability were assessed mesocosm experiment for 58 days. The experimental setup included triplicate...
Benthic–pelagic coupling studies have shown that the response of benthic system to eutrophication is subject complex nonlinear dynamics with specific thresholds beyond which abrupt changes in ecosystem occur and time lags between inputs responses. The “HYPOXIA: regime shifts ” project aimed investigate how nutrient input water column results ecological processes eutrophication, may lead significant, irreversible eastern Mediterranean marine ecosystems within a short period time. included...
