Over the past few decades, we have realized that the silica cycle is strongly intertwined with
other major biogeochemical cycles, like those of carbon and nitrogen, and as such is …

Among the many inhabitants of planktonic communities, several lineages have
biomineralized intricate skeletons. These have existed for millions of years and include the …

Radiolaria are unicellular holoplanktonic protozoa with siliceous or strontium sulfate
skeletons. Mainly studied by micropaleontologists because of their excellent fossil record …

Silicon (Si) is a pivotal element in the biogeochemical and ecological functioning of the
ocean. The marine Si cycle is thought to be in internal equilibrium, but the recent discovery …

Ongoing climate change is predicted to trigger major shifts in the geographic distribution of
marine plankton species. However, it remains unclear whether species will successfully …

The~ 90% biodiversity loss among marine invertebrate species during the end-Permian
mass extinction, the most severe Phanerozoic biocrisis, has been attributed to widespread …

Symbiotic interactions between pelagic hosts and microalgae have received little attention,
although they are widespread in the photic layer of the world ocean, where they play a …

Advances in in situ imaging allow enumeration of abundant populations of large Rhizarians
that compose a substantial proportion of total mesozooplankton biovolume. Using a quasi …

Marine planktonic diatoms are, today, among the world's main primary producers as well as
the main organic carbon exporter to the deep sea despite the fact that they were a very …

Abstract Analysis of 307 species of Radiolaria Polycystina in a worldwide dataset of 4774
plankton, sediment trap, and surface sediment samples allows recognizing six major …
