We studied the distribution of polycystine radiolarians in the northern South China Sea (SCS) in September 2005 in order to document the relation between radiolarian assemblages and environmental parameters. Vertical plankton tows were collected at depth-intervals

Radiolarians are a very diverse microzooplanktonic group, often distributed in regionally restricted assemblages and responding to specific environmental factors. These properties of radiolarian assemblages make the group more conducive for the development

Radiolarian settling fluxes and standing stocks from the central equatorial Pacific are more indicative of physical process than the living environment of the organism. Polycystine radiolaria were collected from plankton and in moored sediment traps along

Since the 1950s, it has become apparent that Radiolaria have significant biostratigraphical potential throughout Phanerozoic time, including the Late Neogene and Quaternary. Radiolarian biozonation schemes for this period have been developed, including

The mean growth, longevity and vitality (based on axopodial morphology and cytoplasmic flow) ofDidymocyrtis tetrathalamus tetrathalamus were assessed in laboratory culture in relation to variations in temperature, salinity and light. Maximum longevity

All present radiolarian taxa were recognized down three Pleistocene piston-cores from the temperate Indian Ocean (38°S–45°S). A biostratigraphical framework was provided byTheocalyptra davisiana curves, major nannofossil events (first appearance ofEmiliania
