    Continental margin fault pattern mapped south-west of Ireland (1977)
    Nature Publishing Group
    In:  Nature, 268 (5622). pp. 720-722.

    Beschreibung: A SIMPLE model for continental basement structures at rifted continental margins comprises large fault blocks which trend approximately parallel to, and step down towards, the continental–ocean boundary (for example, see ref. 1). These blocks may be cut by faults which strike across the margin, and, in many theoretical discussions, are shown as being separated from the true oceanic crust by an intermediate zone (see transitional crust of Fig. 3, ref. 2). On many rifted margins these features are deeply buried by young sediments and cannot be stutied in detail. On Goban Spur (Fig. 1), a marginal plateau south-west of Ireland, the young sediment cover is abnormally thin, however, and we have been able to map in detail a 150 km wide continental basement fracture pattern of horsts and grabens using a simple seismic reflection system (160 inch3 air-gun and two-channel hydrophone array). We also suggest a location for the continent–ocean boundary between the Spur and Porcupine Abyssal Plain. There are few previously published data from Goban Spur relevant to our study, although valuable sampling3 and geophysical3–5 results have been obtained north and south of the area.

    Beschreibung: Processes from above and below influence the sea bottom and its sedimentary cover. The evolution of the lithosphere is being as passionately discussed today as was the evolution of the biosphere a century ago. The physical, chemical and biological interactions at the sea bottom, of "benthic boundary", call for interdisciplinary research.

    Ectothiorhodospira halochloris sp. nov., a new extremely halophilic phototrophic bacterium containing bacteriochlorophyll b (1977)
    Springer
    In:  Archives of Microbiology, 114 (2). pp. 115-121.
    Details
    Publikationsdatum: 2015-03-24
    Beschreibung: A new bacteriochlorophyll b containing phototrophic bacterium was isolated from extremely saline and alkaline soda lakes in Egypt. Enrichment and isolation were performed using a synthetic medium with high contents of sodium carbonate, sodium sulfate and sodium chloride. Photoautotrophic growth occurred with hydrogen sulfide as photosynthetic electron donor. During oxidation of sulfide to sulfate extracellular elemental sulfur globules appeared in the medium. Cells were also capable to grow under photoheterotrophic conditions with acetate, propionate, pyruvate, succinate, fumarate or malate as carbon sources and electron donors. Under these conditions sulfate was assimilated. Optimal growth under the applied experimental conditions occurred at a total salinity of 14–27%, a pH-range between 8.1 and 9.1 and a temperature between 47°C and 50°C. The cells were 0.5–0.6 μm wide and, depending on cultural conditions, 2.5–8.0 μm long; they were spiral shaped, multiplied by binary fission and were motile by means of bipolar flagella. Intercytoplasmic photosynthetic membranes were present as stacks. Bacteriochlorophyll b was the main photosynthetic pigment; small amounts of carotenoids were mainly present as glucosides of rhodopin and its methoxy derivative. The new organism is described as Ectothiorhodospira halochloris.

    First fossil records of cephalopod statoliths (1975)
    Nature Publishing Group
    In:  Nature, 257 (5525). pp. 380-381.
    Details
    Publikationsdatum: 2016-11-15
    Beschreibung: THE class Cephalopoda is represented by over 10,000 fossil species and about 1,000 living species. Almost the entire fossil record so far described consists of external or internal calcareous shells of the Ammonoidea, the Nautiloidea and some members of the Coleoidea. The subclass Coleoidea includes all but three (Nautilus spp.) of the living species of cephalopods, and is represented in the fossil record largely by the order Belemnitida which is important from the early Jurassic to the Eocene. Another coleoid order, the Sepioidea, including the living Sepia and Spirula have internal calcareous shells, and have left traces from the Upper Jurassic (Voltzia) to the present. The three remaining coleoid orders, the Teuthoidea, the Vampyromorpha and the Octopodida include all the remaining living cephalopods, comprising 29 teuthoid or squid families, one vampyromorph family and 12 octopod families.

    Identity of the properties if the Cholinesterases of the optical ganglion fo the squid Ommastrephes bartrami from the South Atlantic and the great Australian Bight (1977)
    Pleiades Publishing | Springer

    Beschreibung: The identity of substrate-inhibitor specificity with respect to several choline esters and organophosphorus compunds was demonstrated for the cholinesterases of the optical ganglion of the squid Ommastrephes bartrami, inhabiting the South Atlantic and the Great Australian Bight. Two cholinesterases with different properties were found in optical ganglia of these squid.
