Two distinct lineages in the radiolarian Order Spumellaria having different ecological preferences
International audience The radiolarian group Spumellaria compose a diverse assemblage of marine microzooplankton with widespread geographic and vertical distributions. Spumellarians are useful paleoceanographic indicators, because their siliceous shells are preserved in the sediment at water depths...

Recent studies on molecular phylogeny based on small subunit ribosomal DNA (SSU rDNA) confirmed spumellarian taxonomic position within radiolarians.

In order to clarify the taxonomy of widely distributed spumellarians, we obtained seven novel SSU rDNA sequences of specimens collected from the subarctic region.

Notably, two groups (Spumellaria land II) are composed of ecologically different species: Spumellaria I consists of temperate to cold water species and one group of Spumellaria II consists of warm water species. These two distinct groups have probably evolved in cold and warm environments, respectively. (C) 2012 Elsevier Ltd. All rights reserved.
