Collodaria

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.

Radolaria #1

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.

Collodaria

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.

Collodaria

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.
