  1. Relocate nests/eggs for artificial incubation: Lizards

    A replicated, controlled study in 1998 in Cádiz province, southern Spain (Díaz-Paniagua 2007) found that artificially incubating common chameleon Chamaeleo chamaeleon eggs resulted in high hatching success, and that hatchling size was affected by the length of an initial cold period during incubation. Overall hatching success was 96%, with just one egg failing during the cold period of incubation (14°C) and two during the warm period (25°C). Hatchling length and body mass were affected by the length of the initial cold period of incubation (results presented as statistical model). In 1998, eggs were collected from seven chameleon nests (82 eggs, 10 or 12 eggs/nest) and incubated in sealed plastic boxes, completely buried in moist vermiculite. Eggs were initially incubated at 14°C for zero, 84, 119 or 149 days (cold period) and then kept at 25°C until hatching (warm period).
