    Evidence for exploitative interspecific competition in mud snails (Hydrobiidae) (1976)
    Wiley-Blackwell
    In:  Oikos, 27 (3). pp. 367-376.
    Details
    Publication Date: 2017-03-31
    Description: Some of the basic assumptions implied in the theory of limiting similarity of coexisting competitors were investigated experimentally in the case of three congeneric, deposit feeding snails. The species show character displacement with respect to size when coexisting. In experimental containers with a natural substrate, interspecific, exploitative competition between snails of the same size range is as intense as intraspecific competition. Diatoms of a given size range, which constitute the most important food, show a "logistic" growth response to grazing, and individual growth of the snails is linearly related to diatom density. The previous observation that the snails show size dependent selection for ingested particle sizes is extended to show that this mechanism leads to a real resource partitioning between snails of different sizes. Size frequency distribution of diatoms in the sediment is a function of the sizes of grazing snails. Size selection of ingested sand grains may also be significant for resource partitioning since the migration rate of the attached microflora between sand grains seems to be slow relative to its growth on the individual sand grains.

    The blind octopus, Cirrothauma (1978)
    Nature Publishing Group
    In:  Nature, 275 (5680). pp. 547-549.
    Details
    Publication Date: 2019-06-20
    Description: THE rare deep-sea octopod Cirrothauma murrayi Chun 1910 was first described from a single specimen caught during the Michael Sars Expedition of 1910 (ref. 1). Until now it has been caught only four more times2. We describe here three specimens of this species that were recently caught during biological cruises of RRS Discovery (Fig. 1). All of these animals, including the Discovery ones, have been caught at depths of more than 1,500 m, except one that was dip-netted through the ice of the Arctic Ocean3.

    Volcanics from the Sierra Leone Rise (1978)
    Nature Publishing Group
    In:  Nature, 275 (5680). pp. 536-538.
    Details
    Publication Date: 2018-01-22
    Description: THE Sierra Leone Rise, located in the east equatorial Atlantic, forms a discontinuous chain of seamounts as shallow as 2 km extending with a general NE–SW trend from near the Sierra Leone coast of Africa, to the St Paul fracture zone near the Mid-Atlantic Ridge (Fig. 1). The origin of this feature has remained a topic of discussion. Sheridan et al.1 have hypothesised that the Sierra Leone Rise is a volcanic structure formed at the beginning of the opening of the Atlantic in the early Cretaceous period. The twin features of the Sierra Leone and the Ceara Rises are probably of oceanic origin and were created 80 Myr ago or later in their present-day position with respect to Africa and South America2. The Atlantic ocean exhibits several similar aseismic structures which appear symmetrically oriented with respect to the mid-oceanic ridge, such as the Walvis–Rio Grande Rise and the Iceland Faeroes–Iceland Greenland Ridges. These structures are volcanic edifices having a composition similar to that found in their associated islands3–7. Deep sea drilling of the Ceara Rise8,9 penetrated a basaltic basement of the upper Cretaceous period (Maestrichtian) (Leg 39, Site 354). Similarly, a DSDP hole (Leg 41, Site 366) on the Sierra Leone Rise, penetrated sediments of the same period, without reaching basement10. We report here the discovery of alkali-rich volcanics in an area of the Sierra Leone Rise. The sediment overlying the rock fragments is aged ∼45 Myr.

    Continental margin fault pattern mapped south-west of Ireland (1977)
    Nature Publishing Group
    In:  Nature, 268 (5622). pp. 720-722.
    Details
    Publication Date: 2016-04-15
    Description: 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.

    The effects of salinity and temperature on the development and survival of fish parasites (1978)
    Wiley-Blackwell
    In:  Journal of Fish Biology, 12 (4). pp. 311-323.
    Details
    Publication Date: 2017-07-11
    Description: In brackish water the variety of marine and freshwater parasite species is considerably reduced. The distribution in brackish water of most marine endoparasites is restricted by the salinity tolerance of their hosts, most of the parasite species are more tolerant than their hosts. The influence of salinity and temperature on nine species has been examined; first stage larvae of Contracaecum aduncum develop in 0-32‰ salinity; Cryptocotyle lingua proved to be infective at salinities down to 4‰. The greatest resistance was found in Anisakis larvae from herring Clupea harengus, which survived for more than half a year. Parasites in the fish intestines appear to be unaffected by changing water salinities, as the osmolarity in the intestines stays nearly constant. Marine ectoparasites (Acanthochondria depressa, Lepeophtheirus pectoralis) survive about three times longer than freshwater species (Piscicola geometra, Argulus foliaceus) when salinity is 16‰. High temperature increases the effects of adverse salinities on parasites. There is evidence that none of these ecto-parasitic species can develop within the range of 7-20‰ salinity.

    Sand deserts during glacial maximum and climatic optimum (1978)
    Nature Publishing Group
    In:  Nature, 272 (5648). pp. 43-46.
    Details
    Publication Date: 2016-09-02
    Description: The past 20,000 yr have witnessed tremendous climatic changes, a glacial maximum at about 18,000 yr BP and a climatic optimum centred on about 6,000 yr BP, both of which mark extreme situations for the Quaternary. This paper attempts to show that active sand dunes were extensive 18,000 yr ago. Conversely, it seems that sand dunes were generally dormant 6,000 yr ago. Thus the former textbook concept1,2 of an arid climatic optimum and a pluvially active glacial maximum is reversed.

    First fossil records of cephalopod statoliths (1975)
    Nature Publishing Group
    In:  Nature, 257 (5525). pp. 380-381.
    Details
    Publication Date: 2016-11-15
    Description: 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.

    Respiration and the effects of pressure on the mesopelagic vertically migrating squid Histioteuthis heteropsis (1978)
    Wiley-Blackwell
    In:  Limnology and Oceanography, 23 (4). pp. 735-739.
    Details
    Publication Date: 2020-11-05
    Description: The effects of hydrostatic pressure and dissolved oxygen concentration on oxygen consumption rates were examined in the mesopelagic, vertically migrating squid Histioteuthis heteropsis from southern California offshore waters. Elevated hydrostatic pressure (to 136 atm) had no significant effects on oxygen consumption rates at 5°C. Lox oxygen concentrations (〈0.5 ml O2 liter -1) depressed rates of oxygen consumption. These findings suggest that biosis may be necessary to supply the total nergy needs of this species at daytime depths in the oxygen minumum layer off southern California.
