摘要

生命史知识对于理解种群生态学非常重要。Diploderma属是龙舌兰科中最具多样性的属之一,迄今为止还没有关于Diplodera物种生活史特征的数据报道。本文首次用骨骼年表揭示了米仓藻种群的年龄和生长情况。雌性比雄性有更大的口鼻部通气口长度(SVL),但性别之间的平均SVL没有显著差异。男女的年龄从1岁到4岁不等,男性的平均年龄为2.24±0.10岁,女性为2.28±0.12岁。无论是年龄结构还是平均年龄,都没有发现显著的性别差异。年龄和体型在两性中均呈显著正相关。生长系数k(雄性:0.510;雌性:0.441)和生长率(雄性:4.33±0.38;雌性:4.91±0.39)在两性中相似。这些结果对该物种的种群动态和管理具有启示意义。

Age and growth of the mountain dragon, Diploderma micangshanense (Squamata: Lacertilia: Agamidae)
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.
