Variation in parental investment and relative clutch mass of the spiny-tail iguana, Ctenosaura pectinata (Squamata: Iguanidae) in central México

We measured the length, width, volume, and weight of 871 freshly laid eggs of 28 clutches of Ctenosaura pectinata. The iguanas were obtained from a tropical dry forest area in central Mexico. The relative clutch mass was related positively to the average egg weight but not to average egg volume. Unl...
