  1. Rediscovery of <em>Boulengerula denhardti</em> Nieden 1912 (Amphibia: Gymnophiona: Caeciliidae) in Meru County, Kenya

    Rediscovery of <em>Boulengerula denhardti</em> Nieden 1912 (Amphibia: Gymnophiona: Caeciliidae) in Meru County, Kenya

    Item type: Journal Article • Journal: African Zoology
    The dearth of information on caecilian amphibians is most likely due to a lack of directed field studies. Here we report the rediscovery of a population of Boulengerula denhardti nearly a century after its description by Nieden in 1912. Morphological...
  2. The occurrence of taste buds in adults of the terrestrial ceacilian <em>Boulengerula boulengeri</em> Tornier, 1898 (Lissamphibia: Gymnophiona: Herpelidae)

    The occurrence of taste buds in adults of the terrestrial ceacilian <em>Boulengerula boulengeri</em> Tornier, 1898 (Lissamphibia: Gymnophiona: Herpelidae)

    Item type: Journal Article • Journal: African Zoology
    Two generations of gustatory organs occur during amphibian ontogeny in frogs and salamanders (Anura and Caudata), and are classified as taste buds or taste discs. Taste buds are present in larval forms, whereas taste discs are typical for adults. The...
  3. Chameleons on the move: survival and movement of the Cape dwarf chameleon, <em>Bradypodion pumilum,</em> within a fragmented urban habitat

    Chameleons on the move: survival and movement of the Cape dwarf chameleon, <em>Bradypodion pumilum,</em> within a fragmented urban habitat

    Item type: Journal Article • Journal: African Zoology
    Reptiles have an amazing diversity of life-history attributes ranging from the shortest- to longest-lived of vertebrate species. Estimating survival in wild populations is of key importance when understanding population dynamics and life-history evolution. However, data are lacking for a large...
  4. Annual variation of ovarian structures of <em>Boulengerula taitana</em> (Loveridge 1935), a Kenyan caecilian

    Annual variation of ovarian structures of <em>Boulengerula taitana</em> (Loveridge 1935), a Kenyan caecilian

    Item type: Journal Article • Journal: African Journal of Herpetology
    The Kenyan caecilian, Boulengerula taitanus inhabits a climate characterised by two distinct dry and wet seasons, and a single thermal minimum in June. It is oviparous with direct development and a remarkable dermatophagous maternal care, but the female reproductive cycle...
  5. A new species of <em>Zygaspis</em> (Reptilia: Squamata: Amphisbaenidae) from north-eastern Mozambique

    A new species of <em>Zygaspis</em> (Reptilia: Squamata: Amphisbaenidae) from north-eastern Mozambique

    Item type: Journal Article • Journal: African Journal of Herpetology
    We describe a new species of Zygaspis based on a single specimen collected in north-eastern Mozambique and deposited in the Natural History Museum of Zimbabwe, Bulawayo. The new species is characterised by its extensively black pigmentation, 191 body annuli, discrete...
  6. Genetic diversity and differentiation of the Western Leopard Toad (<em>Sclerophrys pantherina</em>) based on mitochondrial and microsatellite markers

    Genetic diversity and differentiation of the Western Leopard Toad (<em>Sclerophrys pantherina</em>) based on mitochondrial and microsatellite markers

    Item type: Journal Article • Journal: African Journal of Herpetology
    Intraspecific genetic diversity provides the basis for evolutionary change and is therefore considered the most fundamental level of biodiversity. Mitochondrial DNA (mtDNA) and microsatellite loci are the markers most typically used in population-level studies; however, their patterns of genetic variation...
  7. Freshwater crayfish invasions in South Africa: past, present and potential future

    Freshwater crayfish invasions in South Africa: past, present and potential future

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Freshwater crayfish invasions have been studied around the world, but less so in Africa, a continent devoid of native freshwater crayfish. The present study reviews historical and current information on alien freshwater crayfish species introduced into South Africa and aims...
  8. Cyclic variation of the oviduct structure of <em>Boulengerula taitana</em>, an oviparous species of Gymnophiona: morphological changes, proliferation and apoptosis

    Cyclic variation of the oviduct structure of <em>Boulengerula taitana</em>, an oviparous species of Gymnophiona: morphological changes, proliferation and apoptosis

    Item type: Journal Article • Journal: African Journal of Herpetology
    Functioning of the amphibian oviduct is the subject of many studies, but detailed understanding of caecilian reproduction exists for very few species. In this study, a description is made of morphological changes of the oviduct of the caecilian Boulengerula taitana...
