14. Radiolarians from Leg 134, Vanuatu Region, Southwestern Tropical Pacific1
Greene, H.G., Collot, J.-Y., Stokking, L.B., et al., 1994 Proceedings of the Ocean Drilling Program, Scientific Results, Vol. 134 14. RADIOLARIANS FROM LEG 134, VANUATU REGION, SOUTHWESTERN TROPICAL PACIFIC1 Amy L. Weinheimer,2 Annika Sanfilippo,2 and W.R. Riedel2 ABSTRACT In the cores obtained during Leg 134 of the Ocean Drilling Program, radiolarians occur intermittently and usually in a poor state of preservation, apparently as a result of the region having been at or near the boundary between the equatorial current system and the south-central Pacific water mass during most of the Cenozoic. A few well-preserved assemblages provide a record of the Quaternary forms, and some displaced middle and lower Eocene clasts preserve a record of radiolarians near that subepochal boundary. There are less satisfactory records of middle Miocene and early Miocene to late Oligocene forms. INTRODUCTION RADIOLARIANS AT EACH SITE The locations of Leg 134 drilling sites are indicated in Table 1. All Site 827 of the cores from these sites were examined for radiolarians, but this One or two samples were examined from each of the cores from microfossil group occurred so sparsely and intermittently (see Table Hole 827A.

In this study, we sequenced the Received in revised form 3 August 2009 18S rRNA gene of H. pachydermum and of three spherical spumellarians of Cladococcus viminalis Haeckel, Accepted 7 August 2009 Arachnosphaera myriacantha Haeckel, and Astrosphaera hexagonalis Haeckel. Our molecular phylogenetic analysis revealed that the spumellarian species of C. viminalis, A. myriacantha, and A. hexagonalis form a Keywords: monophyletic group. Moreover, this clade occupies a sister position to the clade comprising the spongodiscid Radiolaria fi Entactinarida spumellarians, coccodiscid spumellarians, and H. pachydermum. This nding is contrary to the results of Spumellarida morphological studies based on internal spicular morphology, placing H. pachydermum in the order Nassellarida Entactinarida, which had been considered to have a common ancestor shared with the nassellarians. 18S rRNA gene © 2009 Elsevier B.V.

First Application of PDMPO to Examine Silicification in Polycystine Radiolaria
Plankton Benthos Res 4(3): 89–94, 2009 Plankton & Benthos Research © The Plankton Society of Japan First application of PDMPO to examine silicification in polycystine Radiolaria KAORU OGANE1,*, AKIHIRO TUJI2, NORITOSHI SUZUKI1, TOSHIYUKI KURIHARA3 & ATSUSHI MATSUOKA4 1 Institute of Geology and Paleontology, Graduate School of Science, Tohoku University, Sendai, 980–8578, Japan 2 Department of Botany, National Museum of Nature and Science, Tsukuba, 305–0005, Japan 3 Graduate School of Science and Technology, Niigata University, Niigata 950–2181, Japan 4 Department of Geology, Faculty of Science, Niigata University, Niigata 950–2181, Japan Received 4 February 2009; Accepted 10 April 2009 Abstract: 2-(4-pyridyl)-5-[(4-(2-dimethylaminoethylaminocarbamoyl)methoxy)-phenyl] oxazole (PDMPO) is a fluo- rescent compound that accumulates in acidic cell compartments. PDMPO is accumulated with silica under acidic con- ditions, and the newly developed silica skeletons show green fluorescent light. This study is the first to use PDMPO in polycystine radiolarians, which are unicellular planktonic protists. We tested Acanthodesmia sp., Rhizosphaera trigo- nacantha, and Spirocyrtis scalaris for emission of green fluorescence. Entire skeletons of Acanthodesmia sp. and Sr. scalaris emitted green fluorescent light, whereas only the outermost shell and radial spines of Rz. trigonacantha showed fluorescence. Two additional species, Spongaster tetras tetras and Rhopalastrum elegans did not show fluorescence. Green fluorescence of the entire skeleton is more like the “skeletal thickening growth” defined by silica deposition throughout the surface of the existing skeleton. The brightness of the fluorescence varied with each cell. This difference in fluorescence may reflect the rate of growth in these cells. Green fluorescence in PDMPO-treated polycystines sug- gests the presence of similar metabolic systems with controlled pH. -

The Distribution of Recent Radiolaria in Surficial Sediments of the Continental Margin Off Northern Namibia
J.rnicropalaeontol.,2: 31 - 38, July 1983 The distribution of Recent Radiolaria in surficial sediments of the continental margin off northern Namibia SIMON ROBSON Marine Geoscience Unit, University of Cape Town, Rondebosch, Cape 'Town 7700, Republic of South Africa ABSTRACT-47 Species of radiolaria have been identified from 30 surface sediment samples collected along transects across the continental margin of northern Namibia between the Kunene River and Walvis Bay. From the distribution patterns of the 24 most abundant species, it was possible to identify a warm water, high salinity population and a cold water, low salinity population. The distribution patterns of each population shows a close correspondence with the known positions of the Angola Current (warm, high salinity water) and the Benguela Current (cold, low salinity water) respectively. Two other trends are apparent from the overall radiolaria distribution ; dilution of the nearshore samples by terrigeneous input and a strong preference for open ocean conditions. There is no apparent correlation with upwelling. REGIONAL SETTING The continental margin of Namibia is a region of Entering the margin from the north is the warm water strong oceanic upwelling (Hart & Currie, 1960; Bremner, ( 16-1 8" C), high salinity (35.3O,100), oxygen poor 1981 and others) and it is situated off an extremely arid (3 mlil) Angola Current. This current reaches a maxi- coastline from which there is low terrigerieous input mum velocity of more than 70cms~sec.off Angola (Bremner, 1976).

Previous work has divided eukaryotic diversity into a small number of high-level ‘supergroups’, many of which receive strong support in phylogenomic analyses. However, the abundance of data in phylogenomic analyses can lead to highly supported but incorrect relationships due to systematic phylogenetic error. Further, the paucity of major eukaryotic lineages (19 or fewer) included in these genomic studies may exaggerate systematic error and reduces power to evaluate hypotheses. -

Von Dr. Ludwig Will Privatdocent für Zoologie (Rostock). I. Allgemeines. A. Weismann wendet sich in seiner Arbeit lieber Leben und Tod (Jena 1884), in der er der Theorie Goette's über den Ursprung des Todes entgegentritt, auch gegen jene Ansicht des letzteren Autors, nach der man in dem Encystirungsprozess der Einzelligen das Analogon des Todes der Metazoen zu sehen habe. Da man einen wirklichen Tod, der Fäulniss und Zersetzung im Gefolge habe, bei den Protozoen künstlich hervor- rufen könne, könne man den gleichen Namen Tod nicht auf die Zustände während der Encystirung anwenden. Verfasser bleibt bei seiner früheren Ansicht, dass bei den einzelligen Organismen ein Tod aus inneren Ursachen, ein natürlicher Tod, nicht vorkomme. Anknüpfend an die Arbeiten Bütschli's, Goette's und Weismann's tritt Moehius der Weismann 'sehen Lehre von der Unsterblichkeit der Protozoen gegenüber. „Nach der bisher allgemein gebräuchlichen Definition versteht man unter Unsterblichkeit eines lebenden indi- viduellen Wesens die ihm innewohnende und durch äussere Ursachen nicht zerstörbare Eigenschaft, als Individuum ewig fortzudauern."

RESUMEN Los radiolarios son protozoos planctónicos marinos, los cuales, a pesar de ser sólo una célula, son sofisticados y complejos organismos. La Subclase Radiolaria está formada por 2 superórdenes: Trypilea y Polycystina, siendo el último el más estudiado, pues su esqueleto de opal es más resistente a la disolución en agua de mar y por ende, más comúnmente preservados en el registro fósil. Los radiolarios han sido usados como una útil herramienta oceanográfica, bioestratigráfica y paleoambiental, gracias a su esqueleto de sílice y a su gran rango geológico. En nuestro país el conocimiento de este grupo es muy escaso, es por esto que el presente trabajo, tiene como principal objetivo, aportar con la identificación y descripción de especies de radiolarios Polycystinos, no antes registrados para esta zona en particular. El material fue recolectado por la Expedición PUCK R/V Sonne Cruise SO-156 Valparaíso-Chiloé-Talcahuano realizada en mayo de 2001.
