  1. Cyclonic eddies reveal Oegopsida squid egg balloon masses in the Agulhas Current, South Africa

    Cyclonic eddies reveal Oegopsida squid egg balloon masses in the Agulhas Current, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    In 2005, 2006, 2007 and 2011, distinct Oegopsida squid egg masses were observed by scuba divers on the narrow southern KwaZulu-Natal (KZN) shelf in depths of 35–50 m off the coastal resorts of Park Rynie, Pumula and Port Edward, South...
  2. Does <em>Serranochromis altus</em> (Teleostei: Cichlidae) exist in the Okavango Delta, Botswana?

    Does <em>Serranochromis altus</em> (Teleostei: Cichlidae) exist in the Okavango Delta, Botswana?

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Two possibly synonymous fish species in the Okavango Delta, Botswana, Serranochromis altus and S. angusticeps, were compared. Ecological data, morphometrics, meristics, allozymes, and genomic fingerprints — generated with six Inter-Simple Sequence Repeat (ISSR) analyses, and DNA barcoding primers — were...
  3. Inadequate taxonomy and highly divergent COI haplotypes in laboratory and field populations of earthworms used in ecotoxicology. A case study

    Inadequate taxonomy and highly divergent COI haplotypes in laboratory and field populations of earthworms used in ecotoxicology. A case study

    Item type: Journal Article • Journal: African Zoology
    DNA barcoding was used to investigate the phylogenetic delimitations of Eisenia sp. populations used in ecotoxicological research in South Africa. A total of three focal groups (used in published works) and two non-focal groups were assessed. These focal groups, including...
  4. DNA barcoding for identification of cryptic species in the field and existing museum collections: a case study of <em>Aethomys</em> and <em>Micaelamys</em> (Rodentia: Muridae)

    DNA barcoding for identification of cryptic species in the field and existing museum collections: a case study of <em>Aethomys</em> and <em>Micaelamys</em> (Rodentia: Muridae)

    Item type: Journal Article • Journal: African Zoology
    DNA barcoding has been proposed as a method for species identification. However, this method has been criticised for its over-reliance on a single mitochondrial gene. In this study, four mitochondrial gene regions and one nuclear gene region were used to...
  5. The invasive Asian green mussel <em>Perna viridis</em> in South Africa: all that is green is not viridis

    The invasive Asian green mussel <em>Perna viridis</em> in South Africa: all that is green is not viridis

    Item type: Journal Article • Journal: African Journal of Marine Science
    The Asian green mussel Perna viridis is an invasive Indo-Pacific species recently reported from South African harbours. To verify the invasion, a phylogenetic (and morphological) analysis of green-shelled mussels (n = 39), found in six South African harbours, was conducted...
  6. The ‘suitcase hypothesis’: Can entrainment of meroplankton by eddies provide a pathway for gene flow between Madagascar and KwaZulu-Natal, South Africa?

    The ‘suitcase hypothesis’: Can entrainment of meroplankton by eddies provide a pathway for gene flow between Madagascar and KwaZulu-Natal, South Africa?

    Item type: Journal Article • Journal: African Journal of Marine Science
    Similarities in the marine fauna found off the coasts of southern Madagascar and KwaZulu-Natal Province (KZN), South Africa, led to the development of the ‘suitcase project,’ with the aim of establishing whether eddies that form off southern Madagascar may package...
  7. Record of Blue tilapia <em>Oreochromis aureus</em> (Steindachner, 1864) in the Eerste River catchment, Western Cape province, South Africa

    Record of Blue tilapia <em>Oreochromis aureus</em> (Steindachner, 1864) in the Eerste River catchment, Western Cape province, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Oreochromis aureus was imported from Israel into South Africa in 1959 but data on its current status in South Africa are lacking. Genomic DNA was extracted and the COI gene amplified at the South African Institute for Aquatic Biodiversity. The...
