Abstract
Knowledge of life history is important for understanding population ecology. The genus Diploderma is one of the most diverse genera in the family Agamidae, and no data on the life history traits of Diploderma species have been reported to date. Here, the age and growth of a population of D. micangshanense were revealed using skeletochronology for the first time. Females have greater snout-vent length (SVL) than males, but the mean SVL did not significantly differ between the sexes. Age ranged from one to four years in both sexes, and mean ages were 2.24 ± 0.10 years for males and 2.28 ± 0.12 years for females. No significant sexual differences were detected in either age structure or mean age. Age and body size were significantly positively correlated in both sexes. The growth coefficient k (males: 0.510; females: 0.441) and growth rate (males: 4.33 ± 0.38; females: 4.91 ± 0.39) were similar in both sexes. These results have implications for the population dynamics and management of this species.
期刊介绍：
Animal Biology publishes high quality papers and focuses on integration of the various disciplines within the broad field of zoology. These disciplines include behaviour, developmental biology, ecology, endocrinology, evolutionary biology, genomics, morphology, neurobiology, physiology, systematics and theoretical biology. Purely descriptive papers will not be considered for publication.
Animal Biology is the official journal of the Royal Dutch Zoological Society since its foundation in 1872. The journal was initially called Archives Néerlandaises de Zoologie, which was changed in 1952 to Netherlands Journal of Zoology, the current name was established in 2003.
