TEMPORAL AND SPATIAL VARIATION IN SURVIVAL RATES OF THE TROPICAL LIZARD ANOLIS-LIMIFRONS

Evaluated survival of Anolis limifrons at 2 sites, AVA and Lutz, at Barro Colorado Island, Panama. Survival of adult females and males did not differ nor did survival of juveniles and adults. Survival was significantly higher at Lutz during 1971-1976 than during 1976-1979 and survival was significantly higher at AVA than at Lutz during 1976-1979. On an annual basis, mean survival rates were 0.042, 0.013, 0.055 for Lutz 1971-1976, Lutz 1976-1979, and AVA 1976-1979, respectively, rates in accord with reports of annual population turnover for this and other small mainland Anolis. Temporal and spatial variation in survival was not associated with habitat, season, year of observation, or numbers and abundances of avian predators. -from Authors
