Temporal dynamics and biogeography of sympagic and planktonic autotrophic microbial eukaryotes during the under-ice Arctic bloom

This study examines the taxonomic composition and biogeography of sympagic and planktonic autotrophic microbial eukaryotes during the Arctic under-ice bloom using metabarcoding.

The community of Marine Alveolate parasites in the Atlantic inflow to the Arctic Ocean is structured by season, depth and water mass

This study examines the seasonal, depth, and water mass structure of marine alveolate parasite communities in the Atlantic inflow to the Arctic Ocean using metabarcoding data.

Arctic phytoplankton spring bloom diversity across the marginal ice zone in Baffin Bay

The paper examines phytoplankton community structure across the marginal ice zone in Baffin Bay using 18S rRNA sequencing and environmental data, identifying distinct community features in under-ice, marginal ice zone, and open water sectors.

metaPR2: a database of eukaryotic 18S rRNA metabarcodes with an emphasis on protists.

The paper introduces metaPR2, a database of processed 18S rRNA metabarcodes annotated with the PR2 reference database, to facilitate comparative studies of protist diversity across environments.

Global patterns and rates of habitat transitions across the eukaryotic tree of life

The paper investigates habitat transitions across eukaryotes, finding frequent salt barrier crossings in major lineages, with fungi showing high transition rates and suggesting non-saline habitats as ancestral.

An 18S V4 rDNA metabarcoding dataset of protist diversity in the Atlantic inflow to the Arctic Ocean, through the year and down to 1000 m depth.

This paper presents a metabarcoding dataset of protist diversity in the Atlantic inflow to the Arctic Ocean, showing seasonal and depth-related variations in protist communities.

No evidence of phago-mixotropy in Micromonas polaris, the dominant picophytoplankton species in the Arctic

The study investigates whether Micromonas polaris is phago-mixotrophic and finds no evidence of bacterial ingestion in any strain.

pr2-primers: an 18S rRNA primer database for protists

The paper develops a database of 179 primers and 76 primer pairs for 18S rRNA metabarcoding of protists, along with a web tool to evaluate their performance.

Taxonomic reassignment of Pseudohaptolina birgeri comb. nov. (Haptophyta)

The paper reassigns Chrysochromulina birgeri to the genus Pseudohaptolina as Pseudohaptolina birgeri comb. nov., based on molecular and morphological data from a cultured strain.

Annual phytoplankton dynamics in coastal waters from Fildes Bay, Western Antarctic Peninsula.

The paper analyzes phytoplankton dynamics in Fildes Bay, Western Antarctic Peninsula, using metabarcoding to reveal seasonal and size-fractionated community patterns and a potential new Micromonas clade.

A user guide to environmental protistology: primers, metabarcoding, sequencing, and analyses

This paper provides a guide for studying protist diversity using molecular methods, focusing on metabarcoding and primer selection for ecological research.

Temporal dynamics of Bacteria, Archaea and protists in equatorial coastal waters

The paper examines microbial community dynamics in equatorial coastal waters of Singapore, finding distinct seasonal patterns in the Singapore Strait but not in the Johor Strait.

Culturable diversity of Arctic phytoplankton during pack ice melting

The paper isolates and characterizes Arctic phytoplankton strains using multiple culturing methods, identifying 276 strains across five divisions and highlighting potential new species.

Mantoniella beaufortii and Mantoniella baffinensis sp. now. (Mamiellales, Mamiellophyceae), two new green algal species from the high Arctic

The paper describes two new green algal species from the Arctic, identified through molecular analysis and morphological comparison with existing species.

Novel diversity within marine Mamiellophyceae (Chlorophyta) unveiled by metabarcoding

The paper uses metabarcoding data to uncover novel diversity within marine Mamiellophyceae, identifying new clades in three genera and suggesting ecological niche adaptations.
