While it contains as much radiolarian informa- tion as you may wish, unfortunately infos from a couple working groups did not make it in print, mostly due to both the intervening holiday season and/or travelling chairmen. I wanted however to get the newsletter out, in order to provide good enough coverage of the coming Interrad meeting... and before it is too late to submit abstracts and register for it. Warm thanks to all those who provided material, information and references for this issue. PRESIDENT’S LETTER Chris Hollis Tena koutou katoa (Greetings to you all), You have barely two months to submit your abstract and register for InterRad 11, the first international radiolarian conference ever to be held in the Southern Hemisphere and hopefully the last international conference I’ll endeavour to convene! I can now confirm what you may have heard from Peter, Paula and others – it’s a big job. But, rest assured of two things: (i) it’s coming together and (ii) the NZ dollar is signifi- cantly lower than it was this time last year. If you’re thinking of choosing a time when the exchange rate is favourable – now is good. When you visit the web site you will note our sponsors’ page is filling up nicely. It has been very heartening to receive generous support from my own institution, Institute of Geological and Nuclear Sciences, our venue hosts, Te Papa Tongarewa, the Royal Society of New Zealand and Ministry of Research Science and Technology, through the Interna- tional Conference Fund, the National Institute of Water and Atmospheric Research (NIWA), the Wellington City Council, Webster Drilling and Exploration and Carl Zeiss Australasia. We hope that some more sponsors will come on board shortly. Really all we need now is YOU! Please register as soon as possible so we can confirm the symposia programmes and excursion details. 1 Forum Radiolaria 23 One further enticement for you, excursion-wise, is the addition of a significant new di- mension to excursion 1A – the Auckland-Wellington tour via the Rotorua-Taupo geother- mal area. Local experts will guide participants through the spectacular morphology changes that track biologically-mediated phase transitions within siliceous sinter deposits in the alkali-chloride and acid-sulphate thermal areas of Waiotapu and other sites in the Rotorua-Taupo area. For some details on current studies see: Lynne, B.Y.; Campbell, K.A. 2004: Morphologic and mineralogic transitions from opal-A to opal-CT in low-temperature siliceous sinter diagenesis, Taupo Volcanic Zone, New Zealand.

Updated information on this and other excursions and other conference information is given on the website: http://www.gns.cri.nz/interrad If you have trouble accessing this website or completing the online registration, I can email or post you the conference details and registration form. Ka kite ana (see you soon), Chris Hollis, convenor InterRad 11 RECENT AND CENOZOIC WORKING GROUP Annika Sanfilippo During the past year the Combined Late Cretaceous-early Paleogene, Cenozoic and Re- cent Working Group had no specific working group projects nor meetings to report on. References with abstracts to the published papers resulting from work by this energetic group are compiled in the general Bibliography section at the end of this newsletter. Despite the Triassic flavour to next year's InterRad conference in New Zealand, the two non-Triassic symposia, the Nigrini Symposium and and the Biosilica Symposium, have a strong focus on themes relevant to Cenozoic workers: paleoclimate, paleoproduc- tivity, paleoceanography, advances in biostratigraphy, radiolarian biology and evolution. Northland and Marlborough excursions provide an opportunity for Cenozoic workers to examine the only radiolarian-rich Cenozoic sedimentary sections known from the Southern Hemisphere: including Cretaceous-Tertiary, Paleocene-Eocene and Eocene-Oligocene boundary sequences. 2 Forum Radiolaria 23 News from Working Group Members and from other colleagues Demetrio Boltovskoy keeps busy on a little project together with Stan Kling, Kozo Takahashi and Kjell Bjorklund, which involves compiling of all the distributional (species specific) Recent rad data, including sediment traps, sediments and plankton samples. The authors are about to finish the first phase of the project - the compilation itself, and will start "cleaning" the data shortly. Below a more detailed description of their effort.... WoRaDD (World Radiolarian Distributional Database) PI’s: Demetrio Boltovskoy, Kjell Bjorklund, Stanley Kling and Kozo Takahashi. Despite the fact that the first radiolarian studies date as far back as the middle of the 19th century, so far there is not a single species for which the world wide distribution in the plankton has been mapped. This situation, common to many marine plankton groups, is chiefly due to the lack of interest in undertaking the complicated and time-consuming task of compiling the abundant distributional information that appeared over the years in individual publications. Absence of this larger, unifying picture not only retards advance- ment of the knowledge in the field of radiolarian biogeography s.s., but also hinders devel- opment of other areas, including assessment of mismatches in the plankton and the sedi- ments, interpretation of sedimentation modes and rates, application of microfossil remains for paleoecologic purposes, etc. This project will compile all the existing (published and unpublished) information on radiolarian (Polycystina) distribution from plankton and sediment trap samples, and from surface sediment materials. The compiled information will be critically “cleaned” and analyzed with the aid of objective numerical and GIS techniques in order to derive global distributional patterns of both species and cell numbers. The project comprises the following phases: Identification and location of the sources of information (publications, web-based databases, internal institutional reports, MSc and PhD theses, etc.). We expect to have identified and located over 95% of the useful data available. So far we have completed entry of the yields of 1118 plankton samples, 492 sediment trap sam- ples, and 2240 surface sediment samples. Data acquisition and entry. Some of the latest databases are available in electronic format, but most earlier information is available in hardcopy format only. Critical evaluation of the data and “cleaning” of the database. This is a crucial aspect of the work, as taxonomic inconsistencies plague the radiolarian

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.

These new data allowed the definition of an updated and sound calpionellid biozonation scheme for the section. In this scheme, the drowning event of a carbonate platform displayed by the facies of the San Vicente Member, the lowermost unit of the section, is dated as Late Tithonian, Boneti Subzone. The Jurassic/Cretaceous boundary was recognized within the facies of the overlying El Americano Member on the basis of the acme of Calpionella alpina Lorenz. The boundary is placed nearly six meters above the contact between the San Vicente and the El Americano Members, in a facies linked to a sea-level drop. The recorded calpionellid bioevents should allow correlations of the Cuban biozonation scheme herein proposed, with other previously published schemes from distant areas of the Tethyan Domain.

  • The Eagle's Nest Is Located in Berchtesgaden
    media information… The Eagle’s Nest (Kehlsteinhaus 1,834m) The so-called Eagle’s Nest teahouse (Kehlsteinhaus) was offered to Adolf Hitler on the occasion of his 50th birthday with the aim of using it for representation purposes for official guests. The challenging construction of the Eagle’s Nest, including the access road was completed in some 13 months’ time. The road leading up to the Eagle’s Nest upper bus terminal area is Germany’s highest and is considered a unique feat of engineering. The brass-line elevator that gives access to the summit is also a distinctive feature of this world-famous attraction. Today the Eagle’s Nest is open to the public and can be seen in its original form. Thanks to its many visitors, proceeds from this sightsseing attraction are used for charitable purposes. Location: The Eagle's Nest is located in Berchtesgaden. Special mountain buses depart every 25 min from Obersalzberg (Kehlsteinbusabfahrt). The journey takes about a quarter of an hour each way. From the parking area at the top, visitors walk 124m (406ft) through a tunnel to the original elevator. The lift transports up to 46 passengers at a time up into the Eagle's Nest building. Local Events and cultural highlights: Road and weather conditions permitting, the building and its road access are open from around mid-May through October. On clear days, visitors to the Eagle’s Nest are rewarded with spectacular views over the Berchtesgaden area, Lake Königssee and Salzburg, as well as with a grandiose mountain panorama of the majestic Berchtesgaden Alps.

FOREWORD Nature conservation and protected areas continue to offer hope to the world un- der circumstances through which the planet faces many profound challenges. De- spite the ongoing destruction and degradation of natural ecosystems as a result of human development, persistent poverty, natural and man-made disasters and accel- erating global climate change, the protected area systems of the world continue to grow in number and extent and attract an increasing share of investment of gov- ernments, development agencies and a wide variety of public and private interests. The Protected Planet Report 2012 provides quantitative measures of this success. It also points towards challenges that remain pertinent, including the challenge of achieving most dimensions of protected area quality. Despite of all the good work, there remain many situations in which protected areas are not managed effectively and at the same time degraded, in which poor governance results in ongoing con- flict and harm, and either as a result of or perhaps leading to situations of unsus- tainable financing.

  • 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.

    Memorial to Rudolf Oskar Brunnschweiler 1915-1986 KEITH R. COLWILL 26 Wattle Avenue, Beaumaris, Victoria 3193 Australia URSULA B. BRUNNSCHWEILER 7Arkana Street, Yarralumla ACT 2600 Australia Why “Pigeons on the Roof’? asked Rudi Brunnschweiler’s daughters when they saw the title page of their father’s latest spare-time project, the draft of a book subtitled “Memoirs of an Explorer.” The title, he replied, was bor­ rowed from an old Swiss proverb that admonishes “rather than chasing pigeons on the roof, be content with the spar­ row in your hand.” No doubt many would have been happy with the sparrow, but not Rudi. He aimed his sights higher, and the challenge this philosophy presented was for him the spice of life, its joy and fulfillment. Rudolf Oskar Brunnschweiler was bom in St. Gallen, Switzerland, on December 12, 1915, the oldest of four children of accountant and pioneer sports pilot Oskar Emmanuel Brunnschweiler and his wife Johanna Martha (nee Vogel), concert pianist; they were citizens of Hauptwil, Canton Thurgau. After his early schooling in Ennenda and Glarus, Rudi entered college at Schiers, from which he matriculated in 1935. He then attended the Federal Technological Institute in Zurich to study civil engineering until mid-1938, when he transferred to the faculty of natural sciences at the University of Zurich. In 1941 he married Emmy (“Micky”) Alwine Kiene. Starting a family in those turbulent war years while still a student took considerable courage. Rudi and Micky’s faith in each other and the future proved to be fully justified, and they shared a happy and adventurous lifetime together.

E-mail: [email protected] Abstract We describe for the first time subtropical intertidal foraminiferal assemblages from beach sands on São Vincente, Cape Verdes. Sixty-five benthic foraminiferal species were recognised, representing 47 genera, 31 families, and 8 superfamilies. Endemic species were not recognised. The new checklist largely extends an earlier record of nine benthic foraminiferal species from fossil carbonate sands on the island. Bolivina striatula, Rosalina vilardeboana and Millettiana milletti dominated the living (rose Bengal stained) fauna, while Elphidium crispum, Amphistegina gibbosa, Quinqueloculina seminulum, Ammonia tepida, Triloculina rotunda and Glabratella patelliformis dominated the dead assemblages. The living fauna lacks species typical for coarse-grained substrates. Instead, there were species that had a planktonic stage in their life cycle. The living fauna therefore received a substantial contribution of floating species and propagules that may have endured a long transport by surface ocean currents. The dead assemblages largely differed from the living fauna and contained redeposited tests deriving from a rhodolith-mollusc carbonate facies at <20 m water depth.

  • Protist Phylogeny and the High-Level Classification of Protozoa
    Europ. J. Protistol. 39, 338–348 (2003) © Urban & Fischer Verlag http://www.urbanfischer.de/journals/ejp Protist phylogeny and the high-level classification of Protozoa Thomas Cavalier-Smith Department of Zoology, University of Oxford, South Parks Road, Oxford, OX1 3PS, UK; E-mail: [email protected] Received 1 September 2003; 29 September 2003. Accepted: 29 September 2003 Protist large-scale phylogeny is briefly reviewed and a revised higher classification of the kingdom Pro- tozoa into 11 phyla presented. Complementary gene fusions reveal a fundamental bifurcation among eu- karyotes between two major clades: the ancestrally uniciliate (often unicentriolar) unikonts and the an- cestrally biciliate bikonts, which undergo ciliary transformation by converting a younger anterior cilium into a dissimilar older posterior cilium. Unikonts comprise the ancestrally unikont protozoan phylum Amoebozoa and the opisthokonts (kingdom Animalia, phylum Choanozoa, their sisters or ancestors; and kingdom Fungi). They share a derived triple-gene fusion, absent from bikonts. Bikonts contrastingly share a derived gene fusion between dihydrofolate reductase and thymidylate synthase and include plants and all other protists, comprising the protozoan infrakingdoms Rhizaria [phyla Cercozoa and Re- taria (Radiozoa, Foraminifera)] and Excavata (phyla Loukozoa, Metamonada, Euglenozoa, Percolozoa), plus the kingdom Plantae [Viridaeplantae, Rhodophyta (sisters); Glaucophyta], the chromalveolate clade, and the protozoan phylum Apusozoa (Thecomonadea, Diphylleida). Chromalveolates comprise kingdom Chromista (Cryptista, Heterokonta, Haptophyta) and the protozoan infrakingdom Alveolata [phyla Cilio- phora and Miozoa (= Protalveolata, Dinozoa, Apicomplexa)], which diverged from a common ancestor that enslaved a red alga and evolved novel plastid protein-targeting machinery via the host rough ER and the enslaved algal plasma membrane (periplastid membrane).

They may be hollow or solid and serve mainly to sediments and as palaeo-oceanographical indicators. support the axopodia. The tangential elements, where Heliozoa are free-floating protists with roughly present, generally form a porous lattice shell of very spherical shells and thread-like pseudopodia that variable morphology, such as spheres, spindles and extend radially over a delicate silica endoskeleton.
