Intraspecific behavioural variation in the lacertid lizard Meroles cuneirostris (Strauch, 1867) (Sauria:Lacertidae)

摘要: AbstractWe characterised behavioural variation between adult male, female and juvenile Meroles cuneirostris, a diurnal lacertid lizard endemic to the Namib Desert. Variation in microhabitat preference was significant age classes, as adults spent more time underneath vegetative cover than juveniles. Movement patterns varied demographic classes juveniles exhibited movements of higher average durations overall, greater percentage moving females. Juveniles turned their heads often adults; all individuals scan surroundings frequently open sand near vegetation. An analysis foraging behaviour indicates that M. cuneirostris exhibits relatively few per minute (MPM) wide range (PTM), making it difficult categorise this species either an ambush or active forager. Furthermore, intraspecific within exists, m...
