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

Phylogeography of unicellular plankton, as representative pelagic organisms, is fundamental to understanding their evolution in the ocean. Historically, these microplankton were believed to have cosmopolitan distributions achieved through passive transport

Plankton tows and surface sediments from the Japan Sea, a marginal sea of the northwestern Pacific, were examined to study the depth distribution of modern radiolarians. The depth distribution patterns between the living assemblage in the water-column

We studied time-series fluxes of radiolarian particles collected by two sediment traps deployed at the eastern (Sta. NAP12t) and western (Sta. CAP12t) sides of the Chukchi Borderland in the Chukchi Sea from 04 October 2012 to 18 September 2013. In order

Radiolarian assemblages were analyzed using samples from the IODP Site U1340 to reconstruct the paleoceanographic conditions in the Bering Sea. Based on the characteristic faunal changes, the radiolarian evolution at Site U1340 was divided into four major
