Sargassum blooms in the tropical North Atlantic have surged to unprecedented levels, causing massive algal tides that severely impact coastal ecosystems. To ...

Many animals benefit from microbial symbionts that aid digestion, supply essential nutrients, or provide defense. When this dependence becomes obligate, as in gutless marine oligochaetes that have los...

Coral skeletons host diverse microbial communities, including endolithic green algae that contribute to holobiont functioning. The siphonous green alga Ostreobium (Bryopsidales) is arguably the best-....

The amoeba Incendiamoeba cascadensis demonstrates that eukaryotic life can withstand temperatures beyond what was thought possible and sheds light on molecular strategies for survival in extreme heat.

Symbiotic interactions involving single-celled eukaryotes have been studied for over a century. This is in part because these microbes occupy nearly all environments and have adapted to survive throu...

The International Society of Protistologists is an association of scientists devoted to research on single-celled eukaryotes, or protists. The ISOP promotes the presentation and discussion of new or i...

Carnivorous sponge–associated iridovirus (CaSpA-IV) is a recently described virus identified in two deep-sea cladorhizid sponge species from the Gulf of Maine and Baffin Bay. To assess its ecological ...

GORG-Dark presents genomes of 9,698 individual bacterial and archaeal cells from the ocean’s sunless interior. The atlas resolves depth stratification to abyssal waters, uncovers particle-attached Pel...

Efficient degradation of fucoidans depends on complementary bacterial guilds that cooperatively break backbone and side-chain sugars, revealing a conserved, globally relevant mechanism that shapes marine carbon cycling.

The Earlham Institute has been awarded funding by the Gordon and Betty Moore Foundation to develop Protist Omics at Scale, a three-year international methods-development programme run in partnership with the Scottish Association for Marine Science, home of the Culture Collection of Algae and Protozoa, and Aalborg University.

Researchers analyzed 369 giant virus genomes and identified widespread genomic islands, regions of rapid gene turnover that help these viruses adapt to hosts and even exchange genes with bacteria, rev...

Background The symbiosis between corals and dinoflagellate algae is disrupted by heat stress, leading to bleaching and subsequent coral mortality, devastating reef habitats. Despite its planetary-scal...

Positive species interactions underpin ecological resilience, which is critical for counteracting anthropogenic pressures on ecosystems. Current research focuses on intra-holobiont interactions betwee...

Abstract. Warnowiid dinoflagellates are known for possessing two of the most complex structures known in single cells: multi-projectile nematocysts and the

Microbial symbionts influence ecological and evolutionary processes in their multicellular hosts; yet they remain poorly characterised in marine systems. Sponges host exceptionally diverse microbiome...

Abstract. Symbiont-bearing benthic foraminifera, like corals, rely on endosymbionts for growth and nutrition and experience bleaching under heat stress. So

Phytoplankton fix half of global CO2 annually and drive key global nutrient cycles. They depend on interactions with bacteria, viruses, and protists. Yet our understanding of these interactions remain...

Labyrinthulomycetes are a class of fungus-like heterotrophic protists from the Stramenopiles lineage, recognized for their ecological role as decomposers and contributors to nutrient cycling. They co...
