DNA metabarcoding on a single organism is a promising approach to clarify the biological
interactions (eg, predator–prey relationships and symbiosis, including parasitism) of difficult …

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 …

ABSTRACT A revised taxonomy of Cenozoic radiolarian families is of particular importance
because exhaustive molecular phylogenetic analyses for Collodaria, Entactinaria …

In marine ecosystems, many planktonic organisms precipitate biogenic silica (bSiO2) to
build silicified skeletons. Among them, giant siliceous rhizarians (> 500 μm), including …

The last two decades have shown the importance of Rhizaria in the biogeochemical cycles
of carbon and silicon in modern oceans. This eukaryotic supergroup, which includes …

Nassellaria are marine protists belonging to the Radiolaria lineage (Rhizaria). Their
skeleton, made of opaline silica, exhibit an excellent fossil record, extremely valuable in …

Metabarcoding technology using high-throughput sequencing has revolutionized the current
understanding of the diversity and ecology of eukaryotic microorganisms. The aim of the …

The phylogenetic affiliation of Oroscenidae, a family of Radiolaria possessing large siliceous
skeletons, was thoroughly revised in this study. Plankton sampling was conducted over …

Polycystina (~ 400-800 living species and several thousand extinct forms) and Phaeodaria
(~ 400-500 living species) are exclusively marine, open-ocean plank-tonic protists, most of …

Entactinaria, an order of Radiolaria, are defined by a specific skeletal structure called “initial
spicular system (ISS)”. The oldest entactinarians appeared in the Ordovician period, and the …
