  1. Spring diet and trophic partitioning in an alpine lizard community from Morocco

    Spring diet and trophic partitioning in an alpine lizard community from Morocco

    Item type: Journal Article • Journal: African Zoology
    Oukaïmeden Plateau is a herpetologically rich locality in the High Atlas (Morocco) where four lizard species coexist in strict sympatry: three lacertids (Lacerta perspicillata chabanaudi, L. andreanszkyi and Podarcis vaucheri – formerly P. hispanica vaucheri) and one gekkonid (Quedenfeldtia trachyblepharus)...
  2. Genetic variation among spiny-footed lizards in the <em>Acanthodactylus pardalis</em> group from North Africa

    Genetic variation among spiny-footed lizards in the <em>Acanthodactylus pardalis</em> group from North Africa

    Item type: Journal Article • Journal: African Zoology
    The systematics of the genus Acanthodactylus was classically based on external morphological traits, osteological characters and morphology of the hemipenes. Although the identification of species complexes is relatively easy, the distinction within some groups is difficult due to a high...
  3. Phylogeography of <em>Buthus</em> Leach, 1815 (Scorpiones: Buthidae): a multigene molecular approach reveals a further complex evolutionary history in the Maghreb

    Phylogeography of <em>Buthus</em> Leach, 1815 (Scorpiones: Buthidae): a multigene molecular approach reveals a further complex evolutionary history in the Maghreb

    Item type: Journal Article • Journal: African Zoology
    The distribution of the scorpion genus Buthus Leach, 1815 includes southwestern Europe, North and Central Africa and extends east towards the Arabian Peninsula. Phylogenetic relationships within the genus are complex and remain partially unresolved despite several previous assessments. A set...
  4. Genetic variability in the ocellated lizard <em>Timon tangitanus</em> in Morocco

    Genetic variability in the ocellated lizard <em>Timon tangitanus</em> in Morocco

    Item type: Journal Article • Journal: African Zoology
    The ocellated lizards in the Timon lepidus/tangitanus/pater complex include the largest lacertids living in continental Europe and North Africa. Long considered a single species (T. pater), the division of the North African ocellated lizards into two species, T. pater in...
  5. Cryptic variation in the Moroccan high altitude lizard <em>Atlantolacerta andreanskyi</em> (Squamata: Lacertidae)

    Cryptic variation in the Moroccan high altitude lizard <em>Atlantolacerta andreanskyi</em> (Squamata: Lacertidae)

    Item type: Journal Article • Journal: African Journal of Herpetology
    Atlantolacerta andreanskyi is a mountain specialist lacertid lizard, restricted to areas above 2400 m of the High Atlas Mountains of Morocco, with apparently no geographic connection between different populations. In a recent molecular study, populations from A. andreanskyi collected across...
  6. Review of the leaf-litter skinks (Scincidae: <em>Panaspis</em>) from the Gulf of Guinea Oceanic Islands, with the description of a new species

    Review of the leaf-litter skinks (Scincidae: <em>Panaspis</em>) from the Gulf of Guinea Oceanic Islands, with the description of a new species

    Item type: Journal Article • Journal: African Journal of Herpetology
    Leaf-litter skinks of the genus Panaspis are currently represented in the oceanic islands of the Gulf of Guinea by two species, Panaspis africana and P. annobonensis. Here we describe a third species, Panaspis thomensis sp. nov., endemic to São Tomé...
  7. The Response of <em>Pinus radiata</em> to Manganese Applications at the Ruitersbos State Forest

    Item type: Journal Article • Journal: South African Forestry Journal
    Although ranked as a minor nutritional problem when compared to the serious phosphate shortages in the Cape forest regions, manganese deficiencies are recorded from time to time, and growth losses have been recorded in P. radiata. Species such as P...
  8. The production of four ryegrass cultivars oversown at various seeding rates into irrigated kikuyu

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    An irrigated kikuyu pasture was oversown, in late March, with four ryegrass cultivars at four seeding rates at Cedara (Natal Mistbelt) and n'Tabamhlope (Highland Sourveld). The oversowing procedure shows promise with the cultivars producing well at both sites. There were...
  9. Methods of capture and transfer to the laboratory of wild pelagic fish

    Methods of capture and transfer to the laboratory of wild pelagic fish

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Two successful methods of capturing anchovy, pilchard and other pelagic fish and transporting them to the laboratory are described.
  10. A note on the incidence and treatment of a bacterial infection of wild pelagic fish maintained in the laboratory

    A note on the incidence and treatment of a bacterial infection of wild pelagic fish maintained in the laboratory

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The pathogens of an eye infection affecting capture-stressed pelagic fish were isolated and identified. Prophylactic use of veterinarian tetracycline was found to be an effective treatment.
