Partioning of a restricted food source in a territorial iguanid (Anolis carolinensis)

Abstract

Following a 48-h deprivation period, time samplings of behavior of six pairs of lizards were taken from 9:30 a.m. to 5:40 p.m. each day for 5 days.

Food offered during the first day of observation was taken in equal amounts by the dominant and nondominant lizards; food offered on the fifth day was taken almost exclusively by the dominant animals (90.4%). This increase is statistically significant (p
