Intra-annual variation of arthropod-plant interactions and arthropod trophic structure in an endangered grassland in the Free State province, South Africa
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: F Buschke --- Centre for Environmental Management, South Africa M Kemp --- Centre for Environmental Management, South Africa M Seaman --- Centre for Environmental Management, South Africa S Louw --- Department of Zoology and Entomology, South AfricaArthropods are valuable biological indicators owing to strong relationships with primary producers. The supposition that arthropod-plant interactions are constant over seasons was tested using Mantel tests on correlations between these groups. A total of 78 plant species and 108 arthropod... -
Habitat use pattern of three species of egrets in a small coastal lagoon in Ghana
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Francis Gbogbo --- Department of Animal Biology and Conservation Science, Ghana Gideon Kwarteng Acheampong --- Department of Animal Biology and Conservation Science, Ghana John-Mark Yaw Atiemo --- Department of Animal Biology and Conservation Science, Ghana Quist Elorm Crepindale --- Department of Animal Biology and Conservation Science, GhanaThe foraging and pattern of habitat use of Western Reef Heron Egretta gularis, Little Egret Egretta garzetta and Great Egret Egretta alba were studied in Sakumo II Lagoon in Ghana to determine the extent of utilisation of non-fish resources by... -
Echidnophaga suricatta (Siphonaptera: Pulicidae), a new species of flea from the Northern Cape Province, South Africa
Item type: Journal Article • Journal: African Zoology • Authors: Michael W. Hastriter --- Monte L. Bean Life Science Museum, Brigham Young University, U.S.A.Echidnophaga suricatta (Pulicidae), a new species of flea collected from the meerkat (Suricata suricatta Schreber, 1776) near Garies (30°22’S, 17°31’E) and Brandvlei (30°27’S, 20°29’E), Northern Cape Province, South Africa, is described. Based on chaetotaxy of the tarsal segments, this new... -
Effect of location and season on the arthropod prey of Nycteris grandis (Chiroptera: Nycteridae)
Item type: Journal Article • Journal: African Zoology • Authors: Sarah Bayefsky-Anand --- Abraham Joshua Heschel School, U.S.A.Analysis of culled arthropod prey parts collected from beneath four feeding perches was used to assess prey taken by Nycteris grandis from November 1987 to May 1988. The perches were located along the Zambezi River in Mana Pools National Park... -
Faecal analysis suggests generalist diets in three species of Western Cape cordylids
Item type: Journal Article • Journal: African Zoology • Authors: S. Clusella-Trullas --- Department of Botany and Zoology, South Africa A. Botes --- Department of Botany and Zoology, South AfricaClimate has been proposed as an explanation for the present-day distribution of closely-related melanistic and non-melanistic cordylid species in the southwestern Cape of South Africa. However, diet may also contribute towards shaping geographic distributions. We present preliminary data on diet... -
Assessing local scale impacts of Opuntia stricta (Cactaceae) invasion on beetle and spider diversity in Kruger National Park, South Africa
Item type: Journal Article • Journal: African Zoology • Authors: M.P. Robertson --- Centre for Invasion Biology, Department of Zoology and Entomology, South Africa K.R. Harris --- Centre for Invasion Biology, Department of Zoology and Entomology, South Africa J.A. Coetzee --- Department of Zoology and Entomology, South Africa L.C. Foxcroft --- Conservation Services, South African National Parks, South Africa A.S. Dippenaar-Schoeman --- Plant Protection Research Institute, Agricultural Research Council, South Africa B.J. van Rensburg --- Centre for Invasion Biology, Department of Zoology and Entomology, South AfricaThere is a paucity of studies examining direct impacts of introduced alien species on biodiversity, a key need for motivating for alien species control in conservation areas. The introduced prickly pear (Opuntia stricta) has invaded some 35 000 ha of... -
Nestling diet of the Algerian Nuthatch Sitta ledanti, an endemic threatened bird in Babors’ Kabylia region (north-eastern Algeria)
