ResumoAbstract The endemic New Zealand skinks, Cyclodina aenea and C. ornata, were examined in the field and laboratory to determine factors that influence their distribution patterns. These lizards share similar population dynamics, reproduction, activity patterns, and habitat selection. Differences were observed in morphology, ethology and, to a certain extent, diet. It is likely that the distribution patterns are controlled by a complex of interrelated factors. Human pressures are probably the most important; directly by habitat destruction or transformation, and indirectly by the introduction of mammalian predators. A model is proposed to help explain current distribution patterns.
