  1. Mitochondrial and nuclear DNA reveals a complete lineage sorting of <em>Glossogobius callidus</em> (Teleostei: Gobiidae) in southern Africa

    Mitochondrial and nuclear DNA reveals a complete lineage sorting of <em>Glossogobius callidus</em> (Teleostei: Gobiidae) in southern Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Glossogobius callidus exhibits broad salinity tolerance and is distributed in both estuarine and freshwater environments in southern Africa. Previous studies revealed substantial morphological and molecular variation among populations, suggesting they constitute a species complex. The present study utilised phylogenetic and...
  2. High-latitude connectivity of the scleractinian coral <em>Acropora tenuis</em> in the south-western Indian Ocean, identified using nuclear intron and mitochondrial sequence data

    High-latitude connectivity of the scleractinian coral <em>Acropora tenuis</em> in the south-western Indian Ocean, identified using nuclear intron and mitochondrial sequence data

    Item type: Journal Article • Journal: African Journal of Marine Science
    All scleractinian corals in southern Africa occupy the high-latitude margins of their biogeographical range, with some straddling multiple biogeographical regions. Connectivity among these populations is essential to maintain genetic diversity, and thus their conservation value. Therefore, the aim of this...
  3. Comparative phylogeography of northwest African <em>Natrix maura</em> (Serpentes: Colubridae) inferred from mtDNA sequences

    Comparative phylogeography of northwest African <em>Natrix maura</em> (Serpentes: Colubridae) inferred from mtDNA sequences

    Item type: Journal Article • Journal: African Zoology
    While the comparative phylogeography of European fauna is relatively well understood, with Pleistocene climatic oscillations leading to ‘southern refugia’ for many species, the equivalent pattern has not been determined for North Africa. In this context variation within North African populations...
  4. Cryptic lineages of little free-tailed bats, <em>Chaerephon pumilus</em> (Chiroptera: Molossidae) from southern Africa and the western Indian Ocean islands

    Cryptic lineages of little free-tailed bats, <em>Chaerephon pumilus</em> (Chiroptera: Molossidae) from southern Africa and the western Indian Ocean islands

    Item type: Journal Article • Journal: African Zoology
    We investigate mitochondrial DNA and craniometric variation in southern African and Malagasy populations of the small and morphologically variable, house-roosting molossid bat, Chaerephon pumilus in relation to Malagasy populations of the related, smaller-sized species, C. leucogaster. Both cytochrome b and...
  5. West-Central African Pleistocene lowland forest evolution revealed by the phylogeography of Misonne’s soft-furred mouse

    West-Central African Pleistocene lowland forest evolution revealed by the phylogeography of Misonne’s soft-furred mouse

    Item type: Journal Article • Journal: African Zoology
    We studied the phylogeographical structure of Praomys misonnei (Rodentia: Muridae) in west-Central Africa based on 113 individuals from 31 localities and the sequencing of two mitochondrial genes (Cytb and CO1). Two clades can be identified through maximum likelihood, bayesian and...
  6. Past connection of the upper reaches of a Lake Tanganyika tributary with the upper Congo drainage suggested by genetic data of riverine cichlid fishes

    Past connection of the upper reaches of a Lake Tanganyika tributary with the upper Congo drainage suggested by genetic data of riverine cichlid fishes

    Item type: Journal Article • Journal: African Zoology
    The Lufubu River is the largest tributary to the southern Lake Tanganyika and its upper reaches are eparated from the lake by rapids that prevent upstream movement of lacustrine fish. Thus, the ichthyofauna of the upper Lufubu River is clearly...
  7. 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...
  8. A comparison of genetic structure in two low-dispersal crabs from the Wild Coast, South Africa

    A comparison of genetic structure in two low-dispersal crabs from the Wild Coast, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    The Wild Coast in south-eastern South Africa is strongly influenced by the warm, southward-flowing Agulhas Current. This current has a significant impact on dispersal in the coastal biota of the region, and facilitates high levels of connectivity among populations. However,...
  9. <em>Marcusenius desertus</em> sp. nov. (Teleostei: Mormyridae), a mormyrid fish from the Namib desert

    <em>Marcusenius desertus</em> sp. nov. (Teleostei: Mormyridae), a mormyrid fish from the Namib desert

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    We critically compared Marcusenius specimens from the mouth of the Cunene River on the Namibia/Angola border, a harsh desert environment on the Atlantic Ocean coast virtually devoid of aerial insects with aquatic larvae which are an important food item, with...
  10. Significant genetic differentiation among meroplanktonic barrel jellyfish <em>Rhizostoma pulmo</em> (Cnidaria: Scyphozoa) in the Mediterranean Sea

    Significant genetic differentiation among meroplanktonic barrel jellyfish <em>Rhizostoma pulmo</em> (Cnidaria: Scyphozoa) in the Mediterranean Sea

    Item type: Journal Article • Journal: African Journal of Marine Science
    Molecular data have shown that jellyfishes are more geographically restricted and evolutionarily divergent than previously thought. We examined genetic variation and divergence within the meroplanktonic barrel jellyfish Rhizostoma pulmo in the Mediterranean Sea; specific sampling areas were the northern Adriatic,...
