Biological control of Rhizoctonia solani by two Trichoderma species isolated from South African composted soil
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: K.S. Yobo --- , Republic of South Africa M.D. Laing --- , Republic of South Africa C.H. Hunter --- , Republic of South Africa M.J. Morris --- , Republic of South AfricaStrains of two Trichoderma species isolated from composted soil were evaluated for biological control of Rhizoctonia solani. Macroscopic observations of in vitro bioassays revealed that the Trichoderma isolates overgrew the pathogen completely and that a brownish discolouration occurred at the... -
Host plants of Osyris lanceolata (African Sandalwood) and their influence on its early growth performance in Tanzania
Item type: Journal Article • Journal: The Southern African Forestry Journal • Authors: P.L. Mwang'ingo Z. Teklehaimanot L.L. Lulandala S.T. MwihomekeIdentification of the host plants of the hemi-parasitic African sandalwood (Osyris lanceolata) and the influence of some on its early growth performance was investigated at Image, Nundu, Sao Hill and Iringa in the southern highlands of Tanzania. The aim was... -
Dual parasitism of Fork-tailed Drongos by African and Jacobin Cuckoos
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Tom P Flower --- Percy FitzPatrick Institute of African Ornithology, DST–NRF Centre of Excellence, South Africa Benjamin J Ashton --- Percy FitzPatrick Institute of African Ornithology, DST–NRF Centre of Excellence, South Africa Elisabet Zöttl --- Percy FitzPatrick Institute of African Ornithology, DST–NRF Centre of Excellence, South Africa Ryan M Olinger --- Percy FitzPatrick Institute of African Ornithology, DST–NRF Centre of Excellence, South Africa Philip AR Hockey --- Percy FitzPatrick Institute of African Ornithology, DST–NRF Centre of Excellence, South AfricaDifferent species of brood parasitic birds, which lay their eggs in the nests of host foster-parents, rarely target the same host species population. We report brood parasitism of Fork-tailed Drongos Dicrurus adsimilis in the southern Kalahari Desert by both African... -
Removal (and attempted removal) of material from a Hooded Vulture Necrosyrtes monachus nest by a starling and a Hooded Vulture
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Lindy J Thompson --- School of Life Sciences, South Africa John P Davies --- Lawson’s Birding, Wildlife and Custom Safaris, South Africa Keith L Bildstein --- Acopian Centre for Conservation Learning, Hawk Mountain Sanctuary, USA Colleen T Downs --- School of Life Sciences, South AfricaRelatively little is documented about nest material theft in vultures. We used camera traps to monitor Hooded Vulture Necrosyrtes monachus nests for a year. We report camera trap photographs of a starling Lamprotornis sp. removing what appeared to be dung... -
Distribution and breeding ecology of the Ferruginous Duck Aythya nyroca in Algeria
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Assia Djelailia --- Laboratoire de Conservation des Zones Humides, Algeria Nasser Baaziz --- Department of Animal Biology, Algeria Farrah Samraoui --- Laboratoire de Conservation des Zones Humides, Algeria Ahmed H Alfarhan --- Department of Botany and Microbiology, Saudi Arabia Boudjéma Samraoui --- Laboratoire de Conservation des Zones Humides, AlgeriaWe conducted a survey of the distribution of Ferruginous Duck Aythya nyroca across Algeria and analysed the influence of nest-site characteristics on nesting success at a Ramsar site, Lake Tonga. The species was found to occupy different wetlands (freshwater lakes,... -
First account of the metazoan parasite fauna of oilfish Ruvettus pretiosus Cocco, 1829 (Perciformes: Gempylidae) in South African waters
Item type: Journal Article • Journal: African Zoology • Authors: Irfan Nunkoo --- Department of Biological Sciences, South Africa Mark J Weston --- Department of Biological Sciences, South Africa Cecile C Reed --- Department of Biological Sciences, South Africa Carl D van der Lingen --- Marine Research Institute and Department of Biological Sciences, South Africa Sven Kerwath --- Department of Biological Sciences, South AfricaParasites are an important but neglected component of ecosystems that can be used as indicators of host biology and ecology. In the present study, the metazoan parasite assemblage of Ruvettus pretiosus, an understudied but widely distributed predatory gempylid, caught off... -
Biology of Litosermyle ocanae in Colombian Pinus patula plantations
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Carlos A Rodas --- Forest Health Protection Programme, Colombia Brett P Hurley --- Department of Zoology and Entomology, Forestry and Agricultural Biotechnology Institute (FABI), South Africa María D Bolaños --- Forest Health Protection Programme, Colombia Ginna M Granados --- Forest Health Protection Programme, Colombia Michael J Wingfield --- Department of Zoology and Entomology, Forestry and Agricultural Biotechnology Institute (FABI), South AfricaPlantations of Pinus spp. in Colombia are severely damaged by various phasmid (Phasmatodea: Diapheromeridae) insects. Of these, Litosermyle ocanae is one of the most serious defoliators. Since 1988, several outbreaks have been recorded in Pinus patula plantations, resulting in substantial... -
Macroparasites of angelfish Brama brama (Bonnaterre, 1788) in the southern Benguela Current ecosystem
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: AL Mackintosh --- Department of Biological Sciences, South Africa CC Reed --- Department of Biological Sciences, South Africa MAI Nunkoo --- Department of Biological Sciences, South Africa PH King --- Department of Biology, South Africa CD van der Lingen --- Department of Biological Sciences, South AfricaThe angelfish Brama brama is a mesopelagic species distributed circumglobally in temperate to warm-temperate waters, including continental-shelf-edge and upper-slope waters of the Benguela Current ecosystem. Little is known about the parasite assemblage of Benguela B. brama, with only three parasite... -
The breeding ecology of Mallard Anas platyrhynchos at Lake Tonga, north-eastern Algeria

Breeding was mainly carried out in stumps of alder carr (Alnus glutinosa)... -
Ectoparasites infecting the heads and gills of commercially valuable marine fishes in South Africa
Item type: Journal Article • Journal: African Zoology • Authors: Mark Weston --- , South Africa Irfan Nunkoo --- , South Africa Cecile Reed --- , South Africa Carl D van der Lingen --- , South AfricaThe South African marine environment is highly diverse, containing >12 000 species of flora and fauna.

A review of parasitic fauna of Egyptian amphibia
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Osama MS Mostafa --- Ain Shams University, Egypt Kareem Morsy --- King Khalid University, Saudi Arabia Saad Bin Dajem --- King Khalid University, Saudi Arabia Mahmoud HY Fedda --- Ain Shams University, EgyptThe world's biodiversity is facing a significant threat, and amphibians are particularly susceptible, being the most vulnerable vertebrate group globally. The decline in the amphibian population has been attributed, in part, to parasitic infection. Egyptian amphibian fauna was poorly studied,...
