In the last decades, environmental metabarcoding has revolutionised biodiversity research, particularly for microbial organisms such as protists, enabling large-scale assessments of diversity and ecol...

Sandin et al. reveal a vast, overlooked molecular diversity of Radiolaria, likely skeleton-less, contrasting the traditional view of their star-shaped skeleton. Such comprehensive Radiolaria diversity...

Abstract. Marine planktonic Radiolaria harboring symbiotic microalgae are ubiquitous in the oceans and abundant in oligotrophic areas. In these low-nutrien

Eukaryotic microorganisms, or “protists,” while often inconspicuous, play fundamental roles in the Earth ecosystem, ranging from primary production and nutrient cycling to interactions with human heal...

The microbial world is diverse and critically important to understanding evolution and global ecology, but we lack teaching and communications resources. This Essay provides a series of technical diag...
