Abstract
We report the effects of incubation temperature on the duration of incubation and hatchling size in the insular lizard Podarcis hispanica atrata. Freshly-laid eggs were placed in artificial nests that were exposed to a natural cyclical variation of microclimate. We monitored substrate temperatures and egg size throughout the incubation period, and measured hatchling size at birth. The mean incubation period was 54 days at average incubation (substrate) temperatures that ranged from 23.5 to 26.5 C. We found a negative relation between the duration of incubation and mean incubation temperature. Overall survival of eggs to hatching was high (83%), even though eggs were frequently exposed for short periods (1-5 h) to high substrate temperatures ( > 35 C). We found no effect of duration of: incubation or incubation temperature on the size of hatchlings.
