The recent rise of red tide harmful algal blooms has induced ecosystem degradation,
economic losses, and aquaculture damage, yet little is known on prevention and mitigation …

Marine plankton support global biological and geochemical processes. Surveys of their
biodiversity have hitherto been geographically restricted and have not accounted for the full …

The eukaryotic picoplankton is a heterogeneous collection of small protists 1 to 3 μm in size
populating surface oceans at abundances of 102 to 104 cells ml− 1. Pigmented cells are …

The ocean is home to myriad small planktonic organisms that underpin the functioning of
marine ecosystems. However, their spatial patterns of diversity and the underlying drivers …

Although protists are critical components of marine ecosystems, they are still poorly
characterized. Here we analysed the taxonomic diversity of planktonic and benthic protist …

Microbial eukaryotes are key components of the ocean plankton. Yet, our understanding of
their community composition and activity in different water layers of the ocean is limited …

Marine plankton form complex communities of interacting organisms at the base of the food
web, which sustain oceanic biogeochemical cycles and help regulate climate. Although …

High-throughput sequencing (HTS) is revolutionizing environmental surveys of microbial
diversity in the three domains of life by providing detailed information on which taxa are …

Marine phytoplankton, the photosynthetic microorganisms drifting in the illuminated waters
of our planet, are extremely diverse, being distributed across major eukaryotic lineages …

Phagotrophic protists are key players in aquatic food webs. Although sequencing-based
studies have revealed their enormous diversity, ecological information on in situ abundance …
