ParAquaSeq, a Database of Ecologically Annotated rRNA Sequences Covering Zoosporic Parasites Infecting Aquatic Primary Producers in Natural and Industrial Systems

Molecular Ecology Resources, Volume 25, Issue 6, August 2025.
ABSTRACT Amplicon sequencing tools such as metabarcoding are commonly used for thorough characterisation of microbial diversity in natural samples. They mostly rely on the amplification of conserved universal markers, mainly ribosomal genes, allowing the taxonomic assignment of barcodes.

A Scavenging Behavior of Cyclammina cancellata (Foraminifera, Rhizaria) on a Crustacean Carcass: Amino Acid Nitrogen Isotope and Microbiome Analyses

Marine Ecology, Volume 46, Issue 3, May/June 2025.
ABSTRACT Cyclammina cancellata is a common benthic foraminifer found at bathyal depths across the world's oceans. Despite its important role in deep‐sea food webs and biogeochemical cycles, the feeding habits of this species remain poorly understood. In this study, we document an aggregation of C.

Geomorphic consequences of freshwater discharge and microbial mats in a macrotidal environment: The case of the beach of Dannes (northern France)

Earth Surface Processes and Landforms, Volume 50, Issue 5, April 2025.
This transdisciplinary study analyses the geomorphic consequences of microbial mats associated with freshwater outflows in a macrotidal environment. Microorganisms were identified using the DNA metabarcoding approach. SEM analysis of quartz collected from the beach surface provided data on the marine and aeolian forces, as well as biological processes ...

Revisions to the Classification, Nomenclature, and Diversity of Eukaryotes

Journal of Eukaryotic Microbiology, Volume 66, Issue 1, Page 4-119, January/February 2019., 2019
Abstract This revision of the classification of eukaryotes follows that of Adl et al., 2012 [J. Euk. Microbiol. 59(5)] and retains an emphasis on protists. Changes since have improved the resolution of many nodes in phylogenetic analyses. For some clades even families are being clearly resolved.
