  1. 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...
  2. 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...
  3. 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...
  4. 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...
  5. 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...
  6. 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...
  7. Nest boxes for Cape Parrots <em>Poicephalus robustus</em> in the Hogsback area, Eastern Cape, South Africa

    Nest boxes for Cape Parrots <em>Poicephalus robustus</em> in the Hogsback area, Eastern Cape, South Africa

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Breeding propensity of tree-cavity nesting bird species are often limited by a shortage of natural nesting sites. Artificial nests can be used to provide alternative nest sites. Cape Parrots Poicephalus robustus are nationally endangered and nest in existing tree-cavities in...
  8. Site Indicator Species for Predicting Productivity of Pine Plantations in the Southern Cape

    Item type: Journal Article • Journal: South African Forestry Journal
    A means of predicting site potential for pine species in the Southern Cape based on 10 vegetation associations is presented.
  9. Reductions in Plant Species Richness under Stands of Alien Trees and Shrubs in the Fynbos Biome

    Item type: Journal Article • Journal: South African Forestry Journal
    The reduction of species richness of indigenous plants is one of the major problems associated with the presence of dense stands of invasive alien trees and shrubs in the Fynbos Biome of the Cape Province, South Africa. A synthesis was...
  10. Floristic and Structural Composition of Wonderwoud Forest in the Wolkberg, North-Eastern Transvaal

    Item type: Journal Article • Journal: South African Forestry Journal
    The closed, evergreen forest of 450 ha was studied by means of a survey of 55 circular plots of 0,04 ha, distributed in a grid pattern. TWINSPAN classification separated the forest into four stand types: Olea capensis macrocarpa—Xymalos monospora—Syzygium gerrardii...
