  1. <em>Ochthebius</em> (<em>s.str</em>.) <em>capicola</em> (Coleoptera) re-discovered in the Cape Peninsula, South Africa

    <em>Ochthebius</em> (<em>s.str</em>.) <em>capicola</em> (Coleoptera) re-discovered in the Cape Peninsula, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    New distributional records and ecological observations are presented for the Cape endemic hydraenid Ochthebius capicola. Considered extinct on the Cape Peninsula, the species has been re-discovered at two adjacent locations as well as at a new site in Tsitsikamma National...
  2. Spawning migrations of Lake Tana <em>Labeobarbus</em> spp. (Teleostei: Cyprinidae) in the Ribb River, Ethiopia

    Spawning migrations of Lake Tana <em>Labeobarbus</em> spp. (Teleostei: Cyprinidae) in the Ribb River, Ethiopia

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Spawning migration of the endemic Labeobarbus species of Lake Tana upstream and downstream of a proposed site for a large dam on the Ribb River, Ethiopia, were investigated to assess the dam's potential impact on these fish. Fish were collected...
  3. Patterns of endemicity and range restriction among southern African coastal marine invertebrates

    Patterns of endemicity and range restriction among southern African coastal marine invertebrates

    Item type: Journal Article • Journal: African Journal of Marine Science
    Southern Africa supports a rich marine biota of 12 734 currently described marine species. Although the distribution and overall species-richness patterns of several component taxa are well documented, studies considering range sizes are absent. This study considers range size frequencies...
  4. Conservation biology and management of a critically endangered cyprinid, the Twee River redfin, <em>Barbus erubescens</em> (Teleostei: Cyprinidae), of the Cape Floristic Region, South Africa

    Conservation biology and management of a critically endangered cyprinid, the Twee River redfin, <em>Barbus erubescens</em> (Teleostei: Cyprinidae), of the Cape Floristic Region, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The Twee River redfin Barbus erubescens is a critically endangered small cyprinid endemic to the Twee River System, a subcatchment of the Olifants-Doring River System of South Africa. It is currently the most threatened freshwater fish in both the Cape...
  5. Conserving the fishes of the Twee River, Western Cape, South Africa: revisiting the issues

    Conserving the fishes of the Twee River, Western Cape, South Africa: revisiting the issues

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The Twee River catchment contains two endemic fish species — the Twee River redfin and the Twee River galaxias — which are threatened by water abstraction, habitat degradation, and the presence of introduced fishes. Fyke nets were used to determine...
  6. Breeding ecology of the Seychelles Black Parrot <em>Coracopsis barklyi</em>

    Breeding ecology of the Seychelles Black Parrot <em>Coracopsis barklyi</em>

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Knowledge of breeding ecology is required for many conservation interventions. The Seychelles Black Parrot Coracopsis barklyi, endemic to the island of Praslin, is vulnerable to extinction. We aimed to improve understanding of C. barklyi breeding ecology to aid conservation planning...

    Item type: Journal Article • Journal: African Journal of Marine Science
    Hydrolagus africanus (Gilchrist, 1922) is a little‑known chimaeroid species, originally described from the KwaZulu‑ Natal coast of South Africa, with a range spanning the western Indian Ocean from Kenya, south to Mozambique and South Africa, and extending into the south‑eastern...
  8. Bird diversity in the savanna habitats of Akagera National Park, Rwanda, in the post-war recovery period

    Bird diversity in the savanna habitats of Akagera National Park, Rwanda, in the post-war recovery period

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    The biodiversity of Akagera National Park (ANP), Rwanda, has reportedly been declining since 1990 due to conflict and war in the country between 1990 and 1994. In this paper, we describe bird diversity in the post-war recovery period. We used...
  9. Effect of large weirs on abundance and diversity of migratory <em>Labeobarbus</em> species in tributaries of Lake Tana, Ethiopia

    Effect of large weirs on abundance and diversity of migratory <em>Labeobarbus</em> species in tributaries of Lake Tana, Ethiopia

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Lake Tana has a remarkable fish diversity, including 17 endemic Labeobarbus species, of which nine spawn in the inflowing rivers. Three of the migratory species are threatened, namely the endangered Labeobarbus macrophtalmus and the vulnerable L. acutirostris and L. platydorsus...
  10. Evidence of multiple divergent mitochondrial lineages within the southern African diplopod genus <em>Bicoxidens</em> Attems, 1928 (Spirostreptida)

    Evidence of multiple divergent mitochondrial lineages within the southern African diplopod genus <em>Bicoxidens</em> Attems, 1928 (Spirostreptida)

    Item type: Journal Article • Journal: African Zoology
    Two recent studies have suggested that divergent mitochondrial lineages may be present within spirostreptid genera such as Bicoxidens Attems, 1928. Bicoxidens, similar to many other endemic soil invertebrates, exhibits low dispersal capabilities and strict microclimate habitat preferences, attributes that often...
