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... -
Solitary individuals in populations of the group-living lizard Ouroborus cataphractus: voluntary or forced?
Item type: Journal Article • Journal: African Zoology • Authors: P. le Fras N. Mouton --- Department of Botany & Zoology, South Africa Janine L. Glover --- Department of Botany & Zoology, South Africa Alexander F. Flemming --- Department of Botany & Zoology, South AfricaWe compared crevice fidelity among solitary and group-living individuals in a population of the group-living lizard Ouroborus cataphractus.

Foraging mode of serpentiform, grass-living cordylid lizards: a case study of Cordylus anguina
Item type: Journal Article • Journal: African Zoology • Authors: A. du Toit --- Department of Zoology, South Africa P. le F.N. Mouton --- Department of Zoology, South Africa H. Geertsema --- Department of Entomology and Nematology, South Africa A.F. Flemming --- Department of Zoology, South AfricaForaging mode of the Cape grass lizard, Cordylus anguina, was determined by using three criteria: 1) the number of movements per minute (MPM) and the percentage of time spent moving (PTM) during periods of activity; 2) prey chemical discrimination ability;... -
