Influence of incubation conditions on hatching success, embryo development and hatchling phenotype of common chameleon ( Chamaeleo chamaeleon ) eggs

摘要: Chameleons lay flexible-shelled eggs that are affected by environmental characteristics during incubation. We incubated of six clutches under four treatments using two different constant temperatures (25 and 29°C) water potentials (-150 kPa and-600 kPa). Eggs gained mass in all treatments, especially the wetter warmer conditions. Temperature, not potential, hatching rate, which was 100% 25°C 64% 29°C. Development time considered as period were both differed between from an average length 98.8 days wettest warmest media to 144.2 driest coldest one. Differences hatchling phenotype mostly explained clutch identity, although it also incubation with bigger heavier hatchlings colder treatments. Incubation conditions did affect growth nor survival rates, but survivors differentiated their higher increase egg Los huevos de los camaleones tienen la cascara flexible, estando influidos por las caracteristicas del medio en que se encuentran. Se incubaron seis puestas cuatro tratamientos, usando dos temperaturas incubacion constantes y potenciales hidricos y-600 incrementaron peso todos principalmente condiciones mas humedas calidas. La tasa eclosion resulto influida el efecto temperatura, pero no potencial hidrico. Eclosiono incubados a apreciaron diferencias duracion desarrollo entre distintos variando promedio dias (en calidas) seco frio). Las apreciadas fenotipo crias atribuyen su origen materno, aunque tambien influencias incubacion, resultando mayor tamano tratamientos menor temperatura. afectaron al crecimiento ni supervivencia crias, sobreviviendo procedian con incremento durante incubacion.
