| Outline of Final Research Achievements |
For the comparisons of calling songs in Platypleura species, seven characteristics including phrase length and six variables characterizing the power spectra were extracted from three segments of a phrase, and then tested whether these characteristics could be used to discriminate between species and localities. Discriminant analysis based on all measured variables resulted in perfect prediction of P. albivannata versus P. yayeyamana, even after a cross validation method was implemented, although no differences could be distinguished in some variables of the ending segment of a phrase. For the examination of weevils, it was determined that the characteristics of distress sounds were differentiated among different reared lineages. In particular, although the slope of the regression between body size and the mean duration of the echeme varied significantly among lineages in males, the regression slopes were almost isotropic throughout localities in females.
