Aggregation in the Banded Gecko, Coleonyx variegatus

Abstract

Aggregation of Ceoleonyx variegatus in diurnal shelter sites is shown to be a statistically valid phenomenon, confirming earlier reports based on subjective impressions.  Preliminary data on causative factors suggest that limited burrow availability promoted aggregation.  Experiments in which two individuals were placed in cages having an excess of burrows revealed no indication of interindividual attraction.  However, these results do not exclude the operation of social factors in aggregation.  On the contrary, pilot data provide hints that the sexes may differ in aggregative behavior.  We hypothesis that lizard density, sex, and physical variables such as temperature and moisture may be associated with joint burrow occupancy.
