摘要
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.
Abstract
In order to investigate the growth and development of Spheniscus demersus chicks,we measured the body mass,body length,bill length,foot length and wing length of 0-7 months old chicks of S.demersus in Shanghai Zoo.Two nonlinear models,Logistic and Gompertz,were used to fit and analyze each body size index of the hatchlings.The results show that both Logistic and Gompertz models had a high fitting degree for each growth indicator of S.demersus,and the fit-ting coefficient(r2)was above 0.970.The Logistic model was used to better fit the growth process of the body mass,body length,bill length and foot length of S.demersus(r2>0.980),while Gompertz model was more suitable for fitting the growth process of wing length.There was a significant correlations between the body size indexes(p<0.01).It is suggested that the body weight and body length could be used as important indicators to monitor and evaluate the health status of S.demer-sus chicks.
