|Abstract||In June 2004, we examined a population of Ameiva erythrocephala in substantially altered habitat on St. Eustatius, Netherlands Antilles. Snout-vent lengths (SVL) of males were greater than those of females for a sexual size dimorphism (SSD) index of 1.37. The adult sex ratio (M:F) of 5:13 differed significantly from 1:1. Estimated population density was 375/ha and biomass was 5.4 kg/ha. Home range size and SVL were not correlated. Male home range sizes did not differ significantly from those of females or those of adults from juveniles. The lowest home range overlaps were between adult males and between adults and juveniles; the highest values were between juveniles, between adult females, and between adult males and females. Activity was unimodal, beginning at about 0930 h, peaking at midday, and ceasing by 1600 h. The proportion of males with regenerated tails was significantly higher than that of females, and individuals with regenerated tails were significantly larger than those with entire tails.|
