Título: | Reproduction of Chamaeleo chamaeleon under contrasting environmental conditions |
Autor: | Díaz-Paniagua, Carmen CSIC ORCID; Cuadrado, Mariano; Blázquez, M.C.; Mateo, José A. | Fecha de publicación: | 2002 | Editor: | British Herpetological Society | Citación: | Herpetological Journal 12: 99- 104 (2002) | Resumen: | Reproductive characteristics of Chamaeleo chamaeleon are described and compared between a dry and a wet year. Nesting occurred in September and October, beginning later in the dry year when females also excavated their nests in longer (but not deeper) tunnels. Females were significantly smaller, with lower body mass, lower clutch mass and lower clutch size in the dry year. Relative clutch mass and body condition did not differ between the two years. Females laid a single clutch of 4-40 eggs, with a mean relative clutch mass of 60-70%. Clutch size was correlated with maternal size, being larger in the wet year, whereas egg variables were independent of maternal characteristics. Higher mortality rate was recorded in the dry than in the wet year. The observed variation in reproductive output may be explained as a consequence of lower availability of food resources in the dry year, resulting in lower fecundity and survival of females. | URI: | http://hdl.handle.net/10261/65826 | Identificadores: | issn: 0268-0130 |
