  1. Hybridisation between native <em>Oreochromis</em> species and introduced Nile tilapia <em>O. niloticus</em> in the Kafue River, Zambia

    Hybridisation between native <em>Oreochromis</em> species and introduced Nile tilapia <em>O. niloticus</em> in the Kafue River, Zambia

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The Nile tilapia Oreochromis niloticus has been introduced throughout Africa outside its native range for aquaculture purposes. Hybridisation between escaped O. niloticus and native Oreochromis species is of concern due to potential negative effects on wild genetic resources for conservation,...
  2. A microsatellite panel for triploid verification in the abalone <em>Haliotis midae</em>

    A microsatellite panel for triploid verification in the abalone <em>Haliotis midae</em>

    Item type: Journal Article • Journal: African Journal of Marine Science
    A method for ploidy verification of triploid and diploid Haliotis midae was developed using molecular microsatellite markers. In all, 30 microsatellite loci were tested in control populations. A final micro satellite multiplex consisting of seven markers were optimised and a...
  3. Preliminary evidence suggests extra-pair mating in the endangered echo parakeet, <em>Psittacula eques</em>

    Preliminary evidence suggests extra-pair mating in the endangered echo parakeet, <em>Psittacula eques</em>

    Item type: Journal Article • Journal: African Zoology
    Parrots are generally considered monogamous, forming strict pairs when breeding. Echo parakeets are unusual in that, although traditional breeding pairs occur, there are also multi-male breeding groups. This raises questions about the potential for extra-pair copulations. Genotype data were obtained...
  4. Spatial genetic pattern in an economically beneficial insect, the cyclical African wild silk moth (<em>Gonometa postica</em>)

    Spatial genetic pattern in an economically beneficial insect, the cyclical African wild silk moth (<em>Gonometa postica</em>)

    Item type: Journal Article • Journal: African Zoology
    The African wild silk moth (Gonometa postica) exhibits large inter-annual population size fluctuations in the Kalahari region of southern Africa. Spent cocoons from this species are currently being utilized in a local silk industry. An understanding of the recolonization dynamics...
  5. Microsatellite DNA analyses reveal population subdivisions among the recently introduced Nile perch (<em>Lates</em> spp.) in Lake Victoria

    Microsatellite DNA analyses reveal population subdivisions among the recently introduced Nile perch (<em>Lates</em> spp.) in Lake Victoria

    Item type: Journal Article • Journal: African Zoology
    Nile perch (Lates spp.) was introduced into Lake Victoria only five decades ago but is now well established and distributed throughout the lake. Given the extensive size of the lake, there is a possibility of isolation by distance that can...
  6. Preliminary insights into the level of genetic variation retained in the endangered echo parakeet (<em>Psittacula eques</em>) towards assisting its conservation management

    Preliminary insights into the level of genetic variation retained in the endangered echo parakeet (<em>Psittacula eques</em>) towards assisting its conservation management

    Item type: Journal Article • Journal: African Zoology
    This study examined a suite of microsatellite markers, originally developed for other parrot species, for their usefulness in providing details about the amount of genetic variation that has been retained in the endangered echo parakeet of Mauritius. Biological samples were...
  7. Genetic diversity within two Tunisian wild jirds: <em>Meriones shawi</em> and <em>Meriones libycus</em> (Rodentia, Gerbillinae)

    Genetic diversity within two Tunisian wild jirds: <em>Meriones shawi</em> and <em>Meriones libycus</em> (Rodentia, Gerbillinae)

    Item type: Journal Article • Journal: African Zoology
    Three Meriones species inhabit Tunisia, namely M. shawi, M. libycus and M. crassus, but little genetic data exist on these gerbils. We collected Meriones from eight localities in Tunisia, and obtained mitochondrial (cytochrome b) and nuclear (IRBP) gene sequence data...
  8. Genetic stock structure of white steenbras <em>Lithognathus lithognathus</em> (Cuvier, 1829), an overexploited fishery species in South African waters

    Genetic stock structure of white steenbras <em>Lithognathus lithognathus</em> (Cuvier, 1829), an overexploited fishery species in South African waters

    Item type: Journal Article • Journal: African Journal of Marine Science
    White steenbras Lithognathus lithognathus (Teleostei: Sparidae) is an overexploited marine fish species endemic to South Africa. Overexploitation in recreational, subsistence and commercial fisheries has resulted in stock collapse and the need for improved management of the species. Adults are thought...
  9. Genetic structure of wild and domesticated grasscutters (<em>Thryonomys swinderianus</em>) from south-western Nigeria

    Genetic structure of wild and domesticated grasscutters (<em>Thryonomys swinderianus</em>) from south-western Nigeria

    Item type: Journal Article • Journal: African Zoology
    Grasscutter (Thryonomys swinderianus) is a large rodent distributed across sub-Saharan Africa that is highly valued as a source of protein. There has been little effort to evaluate the genetic structure of grasscutters despite long-term harvesting pressure and over 40 years...
  10. Genomic resources for the spotted ragged-tooth shark <em>Carcharias taurus</em>

    Genomic resources for the spotted ragged-tooth shark <em>Carcharias taurus</em>

    Item type: Journal Article • Journal: African Journal of Marine Science
    Genomic data can be a useful tool in the management and conservation of biodiversity. Here, we report the development of genomic resources for the spotted ragged-tooth shark Carcharias taurus using genome-wide DNA data from Illumina next-generation sequencing. We explored two...
