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.

Bacterial Diversity in Deep‐Sea Sediments of the North Atlantic Ocean and Their Biosynthesis of Secondary Metabolites

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
In this study, we isolated culturable bacteria associated with oceanic sediments and studied their production of secondary metabolites using metabolomics and genetic screening. Bacteria were cultivated from depths as great as 2000 m below sea level, with the majority of culturable taxa from all sampling sites belonging to the Pseudomonadota phylum. Our

The Role of Summer Temperature on Aquatic Insect Diversity at Multi‐Decadal Scales Within the Holocene

Global Change Biology, Volume 31, Issue 8, August 2025.
We show that regionally across Europe during the last 10,000 years, there is a significant negative relationship between summer temperature and aquatic insect diversity. However, at local, low‐frequency intervals of the same period, we observe only a minor relationship between summer temperature and aquatic insect diversity.

Larval ecomorphology of 13 Libellulidae (Anisoptera, Odonata) of the Middle Rio Doce Valley, Minas Gerais, Brazil

Brazilian Journal of Biology
In the lakes of the Middle Rio Doce, Minas Gerais (MG), two groups of larval Libellulidae are distinguished by preferences of habitat use: one uses mainly aquatic macrophytes and the other uses the bottom substrate. The goal of this work was to verify if
