Survivorship of eggs of the lizard Anolis limifrons was monitored at two sites at Barro Colorado Island in Panama. At AVA and Lutz sites, egg survivorship was 34% and 17%, respectively, over the 40-day incubation period. Of the eggs that did not survive, 15 were killed by ants (Solenopsis spp.), 3 were killed by snails, 2 were killed by unknown predators, and 18 disappeared. At AVA site, the density of lizards was about two times greater than at Lutz site. The results of life-table analyses suggest that the greater density of lizards at AVA site can be attributed to greater egg survival at AVA than at Lutz site.
