  1. The influence of pool size on species diversity and water chemistry in temporary rock pools on Domboshawa Mountain, northern Zimbabwe

    The influence of pool size on species diversity and water chemistry in temporary rock pools on Domboshawa Mountain, northern Zimbabwe

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The effect of pool size (area and depth) on species diversity and physicochemical characteristics of rock pool habitats on Domboshawa Mountain, northern Zimbabwe, was studied from December 2006 to May 2007. Pools were categorised based on maximum depth. Pool duration...
  2. Variations and changes in habitat, productivity, composition of aquatic biota and fisheries of the Kyoga lake system: lessons for management

    Variations and changes in habitat, productivity, composition of aquatic biota and fisheries of the Kyoga lake system: lessons for management

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The Kyoga lake system, which is c. 4 m deep, originally had a diverse fish fauna, extensive macrophytes and wetlands. Most (82%) of its water comes from Lake Victoria, is controlled through three dams and has a short residence time...
  3. Sympatric <em>Biomphalaria</em> species (Gastropoda: Planorbidae) in Lake Albert, Uganda, show homoplasies in shell morphology

    Sympatric <em>Biomphalaria</em> species (Gastropoda: Planorbidae) in Lake Albert, Uganda, show homoplasies in shell morphology

    Item type: Journal Article • Journal: African Zoology
    The three known sympatric Biomphalaria species that occur in Lake Albert; B. choanomphala, B. stanleyi and B. sudanica, were studied using both molecular (COI, 16S and ITS) and shell morphometric data. An unidentified sample of 18 Biomphalaria specimens from Lake...
  4. Sexual dimorphism based on body proportions and ontogenetic changes in the Brazilian electric ray <em>Narcine brasiliensis</em> (von Olfers, 1831) (Chondrichthyes: Narcinidae)<xref ref-type="fn" rid="FN0000"/>

    Sexual dimorphism based on body proportions and ontogenetic changes in the Brazilian electric ray <em>Narcine brasiliensis</em> (von Olfers, 1831) (Chondrichthyes: Narcinidae)<xref ref-type="fn" rid="FN0000"/>

    Item type: Journal Article • Journal: African Journal of Marine Science
    Sexual dimorphism in the Brazilian electric ray Narcine brasiliensis from the south‑western Atlantic coast was evaluated based on body proportions and ontogenetic changes. All regions of the body were found to have differences in body proportions between the sexes, except...
  5. Relationship between somatic growth and otolith growth: a case study of the ornate jobfish <em>Pristipomoides argyrogrammicus</em> from the coast of Réunion (SW Indian Ocean)

    Relationship between somatic growth and otolith growth: a case study of the ornate jobfish <em>Pristipomoides argyrogrammicus</em> from the coast of Réunion (SW Indian Ocean)

    Item type: Journal Article • Journal: African Journal of Marine Science
    The ornate jobfish Pristipomoides argyrogrammicus Valenciennes 1832 occurs in the Indo-West Pacific Ocean, where it is harvested by small-scale coastal fisheries. Management of this species is hindered by lack of adequate biological data. We sampled a total of 113 individuals...
