Cumulated Bibliography of Biographies of Ocean Scientists Deborah Day, Scripps Institution of Oceanography Archives Revised December 3, 2001
Cumulated Bibliography of Biographies of Ocean Scientists Deborah Day, Scripps Institution of Oceanography Archives Revised December 3, 2001. Preface This bibliography attempts to list all substantial autobiographies, biographies, festschrifts and obituaries of prominent oceanographers, marine biologists, fisheries scientists, and other scientists who worked in the marine environment published in journals and books after 1922, the publication date of Herdman’s Founders of Oceanography. The bibliography does not include newspaper obituaries, government documents, or citations to brief entries in general biographical sources. Items are listed alphabetically by author, and then chronologically by date of publication under a legend that includes the full name of the individual, his/her date of birth in European style(day, month in roman numeral, year), followed by his/her place of birth, then his date of death and place of death. Entries are in author-editor style following the Chicago Manual of Style (Chicago and London: University of Chicago Press, 14th ed., 1993). Citations are annotated to list the language if it is not obvious from the text. Annotations will also indicate if the citation includes a list of the scientist’s papers, if there is a relationship between the author of the citation and the scientist, or if the citation is written for a particular audience. This bibliography of biographies of scientists of the sea is based on Jacqueline Carpine-Lancre’s bibliography of biographies first published annually beginning with issue 4 of the History of Oceanography Newsletter (September 1992). It was supplemented by a bibliography maintained by Eric L. Mills and citations in the biographical files of the Archives of the Scripps Institution of Oceanography, UCSD. -

Martin Sander Institute of Palaeontology, University of Bonn, Nussallee 8, 53115 Bonn, Germany The palaeoecology of basal turtles from the Late Triassic was classically viewed as being semi-aquatic, similar to the lifestyle of modern snapping turtles. Lately, this view was questioned based on limb bone proportions, and a terrestrial palaeoecology was suggested for the turtle stem. Here, we present independent shell bone microstructural evidence for a terrestrial habitat of the oldest and basal most well- known turtles, i.e. -

Cerda Co-director: Dr. Marcelo S. de la Fuente 2018 Tesis Doctoral UNCo J. Marcos Jannello 2018 Resumen Las inusuales estructuras óseas observadas entre los vertebrados, como el cuello largo de la jirafa o el cráneo en forma de T del tiburón martillo, han interesado a los científicos desde hace mucho tiempo. Uno de estos casos es el clado Testudinata el cual representa uno de los grupos más fascinantes y enigmáticos conocidos entre de los amniotas. Su inconfundible plan corporal, que ha persistido desde el Triásico tardío hasta la actualidad, se caracteriza por la presencia del caparazón, el cual encierra a las cinturas, tanto pectoral como pélvica, dentro de la caja torácica desarrollada. Esta estructura les ha permitido a las tortugas adaptarse con éxito a diversos ambientes (por ejemplo, terrestres, acuáticos continentales, marinos costeros e incluso marinos pelágicos). Su capacidad para habitar diferentes nichos ecológicos, su importante diversidad taxonómica y su plan corporal particular hacen de los Testudinata un modelo de estudio muy atrayente dentro de los vertebrados. Una disciplina que ha demostrado ser una herramienta muy importante para abordar varios temas relacionados al caparazón de las tortugas, es la paleohistología. Esta disciplina se ha involucrado en temas diversos tales como el origen del caparazón, el origen del desarrollo y mantenimiento de la ornamentación, la paleoecología y la sistemática. -

O’Driscoll National Institute of Water and Atmospheric Research Ltd, Private Bag 14901, Wellington 6241, New Zealand (Received 16 April 2012, Accepted 18 September 2012) The diet of Antarctic silverfish Pleuragramma antarcticum was evaluated by examining stomach ◦ ◦ ◦ ◦ contents of specimens collected in the Ross Sea (71 –77 S; 165 –180 E) in January to March 2008. Pleuragramma antarcticum (50–236 mm standard length, LS) and prey items were analysed for stable-isotopic composition of carbon and nitrogen. According to index of relative importance (IRI), which incorporates frequency of occurrence, mass and number of prey items, the most impor- tant prey items were copepods (81%IRI over all specimens), predominantly Metridia gerlachei and Paraeuchaeta sp., with krill and fishes having low IRI (2·2and5·6%IRI overall). According to mass of prey (M) in stomachs, however, fishes (P. antarcticum and myctophids) and krill domi- nated overall diet (48 and 22%M, respectively), with copepods being a relatively minor constituent of overall diet by mass (9·9%M). Piscivory by P. antarcticum occurred mainly in the extreme south- west of the region and near the continental slope. Krill identified to species level in P. antarcticum stomachs were predominantly Euphausia superba (14·1%M) with some Euphausia crystallopho- rias (4·8%M). -

Of a to− tal of 60 samples, 554 colonies of fungi belonging to 19 genera were identified. Colonies of the genus Cladosporium, Penicillium and non−sporulating fungus (Mycelia sterilia) domi− nated in the examined samples. The microbiological assessment of air for the presence of fungi was also conducted at two points in the station building and two others outside the sta− tion. A total of 175 fungal colonies belonging to six genera were isolated. Colonies of the ge− nus Penicillium were the commonest in the air samples. The potential epidemiological conse− quences for indigenous species as a result of unintentional transport of fungal propagules to the Antarctic biome are discussed in the light of rapid climate change in some parts of the Ant− arctic and adaptation of fungi to extreme conditions. -
