The collected materials were stained with pdmpo and observed by the following method. As this is the first report to apply pdmpo to polycystine radiolarians, the detailed procedures are explained as follows (fig. 2): 1) the collected material was filtered through a sieve with a 1-mm opening to remove 1mm plankton,.

Collodaria is a unicellular order under the phylum radiozoa and the infrakingdom rhizaria. Like most of the radiolaria taxonomy, collodaria was first described by ernst haeckel, a german scholar who published three volumes of manuscript describing the extensive samples of radiolaria collected by the voyage of hms challenger. Recent molecular phylogenetic studies concluded that there are collodaria contains three families, sphaerozodae, collosphaeridae, and collophidilidae.
Forty-six samples were collected from all slices of the bancheng formation in the shiti section. The fragmented samples were soaked in a 4% hf solution for 10 h at room temperature. After discarding the supernatant liquid, the acid residues were transferred to other containers, then water was added until the residues were greatly diluted.

This report summarizes the radiolarian analyses from plankton-tow samples, comparing fauna1 abund- ances with those reported from the open ocean as well as with fauna preserved in the underlying recent sur- face sediments. Methods radiolaria were collected at 14 stations using 75 cm diameter, 64 micron-mesh plankton nets equipped.

Hays radiolaria slide collection consists of tens of thousands of slides from hundreds of mostly lamont-doherty earth observatory deep-sea sediment cores. The slides, prepared between the late 1960’s and 2012, are primarily from the antarctic south of 40° latitude, the north pacific north of 40°, and the equatorial pacific between 10°n and 10°s.

The radiolaria have been sourced and identified by collection of fossil samples from barbados sites at bissex hill, bath cliff, pico de teneriffe and the most famous, springfield. Although there's relatively little distance between them, each location presents differences in the distribution of species.
Radiolarians were collected from surface seawater (up to 3 m depth) on may 28, 1999, using a plankton-net (60-cm circle opening with 37-μm mesh net) at one station (site 990528; 26°37′18″n, 127°47′35″e) approximately 5 km northwest of okinawa island, japan plankton samples were diluted with seawater collected at the sampling site.

It has been hypothesized that increased water column stratification has been an abiotic “universal driver” affecting average cell size in cenozoic marine plankton. Gradually decreasing cenozoic radiolarian shell weight, by contrast, suggests that competition for dissolved silica, a shared nutrient, resulted in biologic coevolution between radiolaria and marine diatoms, which expanded.
