  1. The autumn occurrence and spatial distribution of cetaceans in the waters of Mauritania during a geophysical survey in 2012

    The autumn occurrence and spatial distribution of cetaceans in the waters of Mauritania during a geophysical survey in 2012

    Item type: Journal Article • Journal: African Journal of Marine Science
    This study aimed to identify the occurrence and spatial distribution of cetaceans in Mauritanian waters (eastern Atlantic). A geophysical survey was conducted over 92 days between September and December 2012. Over 967 km was surveyed, with 1 017 h of...
  2. <em>Scaeurgus unicirrhus</em> (Orbigny, 1840) (Cephalopoda, Octopodidae): first record from the South-East Atlantic

    <em>Scaeurgus unicirrhus</em> (Orbigny, 1840) (Cephalopoda, Octopodidae): first record from the South-East Atlantic

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The first recorded specimens of Scaeurgus unicirrhus from the South-East Atlantic are described. Five males and two females were captured on the Valdivia Bank, Walvis Ridge, between 24 and 27°S, 400 miles off the Namibian coast. They are compared with...
  3. Imbibition and germination of seeds of three <em>Acacia</em> species from Ethiopia

    Imbibition and germination of seeds of three <em>Acacia</em> species from Ethiopia

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Imbibition and germination of seeds of three Acacia species from Ethiopia, namely Acacia nubica, A. seyal and A. horrida, were tested in laboratory conditions. Heat treatments had a positive effect on imbibition rates for all three species. The best treatment...
  4. Ecological factors affecting the early development of seedlings of three <em>Acacia</em> species from Ethiopia

    Ecological factors affecting the early development of seedlings of three <em>Acacia</em> species from Ethiopia

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Three Acacia species from Ethiopia, namely Acacia nubica, A. seyal and A. horrida, were tested for growth and resistance to drought during the establishment phase in glasshouse and laboratory conditions. The experiments showed that each species has different preferences for...
  5. The importance of cephalopods to trawl fisheries in the western Mediterranean

    The importance of cephalopods to trawl fisheries in the western Mediterranean

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The aim of the study was to define the commercial importance of cephalopods caught by trawlers from five Italian and Spanish Mediterranean ports. From summer 1995 to spring 1996, samples of the catches of trawlers were taken on board. The...
  6. A preliminary investigation on how meteorological changes may affect beach-seine catches of <em>Lougo vulgaris</em> in the Thracian Sea (Eastern Mediterranean)

    A preliminary investigation on how meteorological changes may affect beach-seine catches of <em>Lougo vulgaris</em> in the Thracian Sea (Eastern Mediterranean)

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Daily catches of Loligo vulgaris and the fishing effort of commercial beach-seiners operating along the coasts of the Thracian Sea were recorded between October 1994 and May 1995. Taking into account the spatial distribution of the ports, the squid fishing...
  7. Composition and spatial distribution of cephalopods in two north-western Mediterranean areas

    Composition and spatial distribution of cephalopods in two north-western Mediterranean areas

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The faunistic composition and the spatial distribution of the cephalopod fauna were studied and compared in two areas of the north-western Mediterranean: the Catalan Sea (Spanish coast) and the northern Tyrrhenian Sea (Italian coast). In all, 46 species were collected...
  8. On Moduli of Convexity in Banach Spaces

    On Moduli of Convexity in Banach Spaces

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    We provide an example to show that the moduli of convexity δE and βE are different. Our example allows us to prove that 2 is the best possible constant in the inequality δE ≤ β E ≤ 2 δ E...
  9. On moduli of convexity and some applications

    On moduli of convexity and some applications

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    We provide some properties of both moduli of convexity δ and β and derive some applications of the modulus β to the geometry of Banach spaces as well as fixed point theory.
  10. Morphological and molecular evidences within <em>Osmundea</em> (Ceramiales, Rhodophyta) from the Canary Islands, eastern Atlantic Ocean

    Morphological and molecular evidences within <em>Osmundea</em> (Ceramiales, Rhodophyta) from the Canary Islands, eastern Atlantic Ocean

    Item type: Journal Article • Journal: African Journal of Marine Science
    The genus Osmundea is a strongly supported monophyletic group within the Laurencia complex and shows a disjunct distribution occurring in the North-East and South-West Pacific, the Indian and Atlantic oceans and the Mediterranean Sea. Its phenotypic plasticity on the Canary...
