oa Madoqua - The distribution of the genus Rhoptropus (Reptilia, Gekkonidae) in the central Namib Desert
The diurnal gecko genus Rhoptropus is typical to the northern Namib Desert and adjacent inland areas. Three species extend southwards into the Namib-Naukluft Park. A detailed survey of the distribution shows very diverging patterns for each of these species south of the Swakop River and this situation is discussed with reference to habitat preference related to stratigraphy, substratum and possible effect of competition with sympatric lizard species.
