Abstract
为探讨斑嘴环企鹅(Spheniscus demersus)雏鸟的生长发育特征,对上海动物园0~7月龄斑嘴环企鹅雏鸟的体质量、体长、喙峰长、脚长和翅长进行测定,并利用Logistic和Gompertz两种非线性数学模型对各项体尺指标进行拟合分析。结果表明:Logistic和Gompertz两种模型的拟合度均较高,拟合系数(r2)均达0.970以上。斑嘴环企鹅的体质量、体长、喙峰长和脚长的生长过程用Logistic模型的拟合效果更佳(r2>0.980),而翅长的生长过程用Gompertz模型效果更佳。斑嘴环企鹅各项体尺指标存在极显著相关性(p<0.01),建议将体质量和体长作为监测斑嘴环企鹅健康状况的重要指标
