  1. The taxonomy and growth of a <em>Crypthecodinium</em> species (Dinophyceae) isolated from a brackish-water fish aquarium

    The taxonomy and growth of a <em>Crypthecodinium</em> species (Dinophyceae) isolated from a brackish-water fish aquarium

    Item type: Journal Article • Journal: African Journal of Marine Science
    An unidentified heterotrophic dinoflagellate found growing in abundance in a brackish-water fish aquarium was isolated and serially cultivated using a fish cell line as the food source. Prominent characteristics of this dinoflagellate included a cingulum that did not fully encircle...
  2. 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...
  3. Significant population genetic structuring of the holoplanktic scyphozoan <em>Pelagia noctiluca</em> in the Atlantic Ocean

    Significant population genetic structuring of the holoplanktic scyphozoan <em>Pelagia noctiluca</em> in the Atlantic Ocean

    Item type: Journal Article • Journal: African Journal of Marine Science
    Pelagia noctiluca is thought to have a global distribution, yet our understanding of genetic connectivity across the range of this problem animal is poor. Here, we investigate the genetic structure of populations off southern Africa using mitochondrial COI and nuclear...
  4. Phylogenetic relationships among members of the <em>Pachydactylus capensis</em> group of southern African geckos

    Phylogenetic relationships among members of the <em>Pachydactylus capensis</em> group of southern African geckos

    Item type: Journal Article • Journal: African Zoology
    Phylogenetic relationships among members of the Pachydactylus capensis group of southern African geckos
  5. The phylogenetic affinities of the Socotra Bunting <em>Emberiza socotrana</em>

    The phylogenetic affinities of the Socotra Bunting <em>Emberiza socotrana</em>

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    The monophyly of the African ‘brown bunting’ complex was corroborated by a recent molecular study. However, the little-known Socotran endemic Emberiza socotrana, which is morphologically similar to the other taxa in this complex, was not included. Here we present a...
  6. Identification of the marine diatom <em>Pseudo-nitzschia multiseries</em> (Bacillariophyceae) as a source of the toxin domoic acid in Algoa Bay, South Africa

    Identification of the marine diatom <em>Pseudo-nitzschia multiseries</em> (Bacillariophyceae) as a source of the toxin domoic acid in Algoa Bay, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    A unialgal culture of a Pseudo-nitzschia species dominant in the plankton of Algoa Bay in the spring of 2012 was established by isolation of clonal chains of cells. Identification of the species as Pseudo-nitzschia multiseries was based on frustule morphometrics...
  7. Host use does not clarify the evolutionary history of African ticks (Acari: Ixodoidea)

    Host use does not clarify the evolutionary history of African ticks (Acari: Ixodoidea)

    Item type: Journal Article • Journal: African Zoology
    Where host-parasite associations are rigid and unique, the host preference(s) of parasites and the evolutionary relationships between their hosts may offer insights into the parasites’ evolu–tionary history. Where such associations are less rigid, however, the assumption that current host preferences...
  8. Relationships of the <em>Pachydactylus rugosus</em> group of geckos (Reptilia: Squamata: Gekkonidae)

    Relationships of the <em>Pachydactylus rugosus</em> group of geckos (Reptilia: Squamata: Gekkonidae)

    Item type: Journal Article • Journal: African Zoology
    We examined phylogenetic relationships of the Pachydactylus rugosus complex using DNA sequence data from segments of the mitochondrial genes cytochrome b and 16S ribosomal RNA. These molecular data support the contention that members of the rugosus complex, as defined by...
  9. Phylogeography and genetic diversity of <em>Psammophis schokari</em> (Serpentes) in North Africa based on mitochondrial DNA sequences

    Phylogeography and genetic diversity of <em>Psammophis schokari</em> (Serpentes) in North Africa based on mitochondrial DNA sequences

    Item type: Journal Article • Journal: African Zoology
    The snake Psammophis schokari has a widespread distribution across North Africa, and in Morocco/Western Sahara is represented by three different morphotypes: striped, unicoloured and the Western-Sahara morph. ND4 mitochondrial DNA sequences from 28 specimens comprising 20 P. shokari, two P...
  10. 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...
