Item type: Journal Article • Journal: African Zoology • Authors: D. Peinke --- Wildlife and Reserve Management Research Group, Department of Zoology and Entomology, South Africa R.T.F. Bernard --- Wildlife and Reserve Management Research Group, Department of Zoology and Entomology, South AfricaThe life history of the springhare (Pedetes capensis, Forster, 1778) at 33°S, in the Eastern Cape Province of South Africa, was characterized by continuous, aseasonal and asynchronous reproduction.

Does the cellphone radio-frequency electromagnetic radiation during ringing or talking modes induce locomotor disturbance in Drosophila melanogaster?
Item type: Journal Article • Journal: African Zoology • Authors: Mervat A Seada --- Zoology Department, Faculty of Science, Egypt Samar E Elkholy --- Zoology Department, Faculty of Science, Egypt Wesam S Meshrif --- Zoology Department, Faculty of Science, EgyptDebate regarding the biological effect of electromagnetic radiation has been recently raised. The effects of this radiation on locomotor activity are not well known. Hence, in this study, we used Drosophila melanogaster as a model organism to investigate the possible... -
Behavioural response as a reliable measure of acute nanomaterial toxicity in zebrafish larvae exposed to a carbon-based versus a metal-based nanomaterial
Item type: Journal Article • Journal: African Zoology • Authors: Sarel J Brand --- Unit for Environmental Sciences and Management, South Africa Tarryn L Botha --- Unit for Environmental Sciences and Management, South Africa Victor Wepener --- Unit for Environmental Sciences and Management, South AfricaProduction, use and disposal of products containing nanomaterials can lead to an increased presence of these particles in the environment and exposure to the organisms found there. It is therefore becoming increasingly necessary to develop methods for screening these materials...
