We also found a positive correlation between the water column stratification estimated via the mixed-layer depth , suggesting that the collodarian diversity increase with a deeper stratification of the ocean.Next

All sequences have been deposited in the GenBank database under accession numbers , —. Later the Radiolaria during the late Paleozoic showed a progressive decrease until the end of the Jurassic, where they underwent an accelerated diversification. Despite our extensive geographical coverage, most of the stations sampled were located in tropical and temperate zones, with only a few coastal conditions and a limited number of polar sampling stations.
For each sampling station, we did not find significant differences in OTU composition between the four different size fractions nor the two depths and consequently pooled all the sequences from different samples collected in the same sampling station for statistical analyses of the OTU composition and richness.

Besides their diversity of form, radiolarians also exhibit a wide variety of behaviors.

Swarm: robust and fast clustering method for amplicon-based studies.
The life cycle of radiolaria is complex, since they are voracious predators of large prey, that is, they need to eat other microorganisms of the same size or greater than theirs every day or every two days. The horizontal purple bars indicate latitudes known for good radiolarian silica preservation, based on surface sediment composition.Next

It is common for the Spumellarians to have several concentric shells connected by radial bars.
Brandotodium nutricula is a common endosymbiont of Collodarians. We found no significant correlation between OTU richness and sea temperature , whereas it has been suggested earlier that collodarian diversity may increase towards warmer waters.Next
Indian Ocean LM Pylospira octapyle Haeckel? It was estimated that the lineage of Radiolarians, the ancestors of Collodaria, arose in early.
