OBSERVATIONS ON THE DISTRIBUTION, EMERGENCE AND BEHAVIOUR OF CENTRAL AFRICAN CHAOBORIDAE
Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa • Authors: SA Mitchell --- Unit for Limnology, South AfricaThe distribution of four species of Chaoboras over selected parts of Zimbabwe is given. The effect of temperature on the duration of the larval life cycle is discussed in relation to the generation time and the lunar periodicity of the... -
Occurrence of larval fishes in a rocky shore-associated nursery area in temperate South Africa, with emphasis on temperature-related growth in dominant Sparidae
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: NA Strydom --- Nelson Mandela Metropolitan University, South Africa AJ Booth --- Department of Ichthyology and Fisheries Science, South Africa A McLachlan --- Nelson Mandela Metropolitan University, South AfricaLarval fishes were studied in Shark Bay on the warm, temperate south-east coast of South Africa. The bay is a small, shallow, subtidal area associated with a rocky shore. Sampling took place fortnightly for a period of one year (September... -
Foraging behaviour of two rodent species inhabiting a kopje (rocky outcrop) in Tsavo West National Park, Kenya
Item type: Journal Article • Journal: African Zoology • Authors: Benjamin G. Fanson --- Department of Biological Sciences, U.S.A. Kerry V. Fanson --- Department of Biological Sciences, U.S.A. Joel S. Brown --- Department of Biological Sciences, U.S.A.We employed patch use theory to evaluate how several environmental factors influence the foraging behaviour of two rodent species: Grammomys dolichurus and Acomys cahirinus. Foraging efficiency was determined by measuring the remaining food in artificial food patches (giving-up densities: GUDs)... -
>Utilization of shallow subtidal bays associated with warm temperate rocky shores by the late-stage larvae of some inshore fish species, South Africa
Item type: Journal Article • Journal: African Zoology • Authors: Nadine A. Strydom --- South African Institute for Aquatic Biodiversity, South Africa>This work describes the utilization of shallow, subtidal bays, associated with rocky shores, by the late-stage larvae and early juveniles of some common inshore fishes. Larval and early juvenile fishes were collected in seven small bays (30–50 m wide) between...
