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
