Abstract

Peak density of animals ranged from 17-35 animals per hectare (not including hatchlings). Males were most abundant in May and June. Females peaked in abundance in August after the eggs hatched. Yearlings were significantly smaller than adults until the end of June. Hatchlings were first seen August 2. Skinks were sexually dimorphic with males having wider heads and tails than females. Females were significantly heavier than males prior to oviposition and significantly lighter afterwards. The weight of females remained depressed during the nesting period. Sex ratios were unbiased during the breeding period. Individuals aggregated spatially within age and sex classes. Males and females significantly associated during the breeding period. Yearlings and males were significantly more likely to be non-resident than females. Yearlings were found using twice as many microsites as adults. Artificial debris made up almost 50 per cent of microhabitat available to and used by the skinks. (Abstract shortened by UMI.)Dept. of Biological Sciences.
