Application and Prospect of Morphometry in the Identification of Three Commonly Involved Parrot Eggs
In order to improve the efficiency of identifying the species and species of parakeet eggs in practi-cal work,and to explore the morphological differences of parakeet eggs,parakeet eggs and eclectic parakeet eggs,the experimental samples from the Forest Public Security Forensics Center of State Forestry Administration were studied by using traditional morphometry and geometric morphometry.The results of conventional morphom-etry showed that there were significant differences in the short diameter length between the eggs of Parakeet SUNS and the eggs of Parakeet SUNS and the eggs of Parakeet SUNS and the eggs of Parakeet SUNS and the eggs of Parakeet SUNS and the eggs of Parakeet greys(P＜0.05).There was no significant difference between eclectic parrot eggs and grey parrot eggs.The 50 points on the parrot egg were selected by using TPSDig 232 software through the method of outline,and the known data were superimposed by Past 4.01 software.Finally,SPSS soft-ware was used to conduct multivariate analysis of variance and discriminant analysis respectively to study the fea-sibility of using shape to distinguish three kinds of parrot eggs.TPSRelw software was used to analyze the relative distortion of three kinds of Parrot eggs after Platt's superposition,and the differences of the three kinds of Parrot eggs could be seen more clearly.The results of geometric morphometry showed that 100％of the original grouped cases could be correctly classified.After removing the influence of size,the three kinds of parrot eggs were dif-ferent in shape,which could be used to distinguish the grey parrot,the sun cone parrot and the eclectic parrot.
