Identification of Tibicen cicada species by a Principal Components Analysis of their songs
Specific identification of three Tibicen cicadas, T. japonicus, T. flammatus and T. bihamatus, by their chirping sounds was carried out using Principal Components Analysis (PCA). High quality recordings of each species were used as the standards. The peak and mean frequencies and the pulse rate were...

| description | Specific identification of three Tibicen cicadas, T. japonicus, T. flammatus and T. bihamatus, by their chirping sounds was carried out using Principal Components Analysis (PCA). High quality recordings of each species were used as the standards. The peak and mean frequencies and the pulse rate were used as the variables. Out of 12 samples recorded in the fields one fell in the vicinity of T. japonicus and all other were positioned near T. bihamatus. Then the cluster analysis of the PCA scores clearly separated each species and allocated the samples in the same way.<br>A identificação de três espécies de cigarras do gênero Tibicen, T. japonicus, T. flammatus e T. bihamatus, através de seus sons estridentes foi realizada por meio da Análise de Componentes Principais (PCA). Gravações de alta fidelidade de cada espécie foram usadas como referencias. As variáveis usadas foram as freqüências máxima e média e a taxa de pulsos. Das 12 amostras gravadas no campo, uma foi colocada perto de T. japonicus e as outras perto de T. bihamatus. A análise de conglomerados dos valores da PCA separou claramente cada espécie e posicionou as amostras da mesma maneira. |
