Abstract
Lavine, B.K., Morel, L., Vander Meer, R.K., Gunderson, R.W., Han, J.H., Bonanno, A. and Stine, A., 1990. Pattern recognition studies in chemical communication: nestmate recognition in Camponotus floridanus. Chemometrics and Intelligent Laboratory Systems, 9: 107–114. The combination of gas chromatography and pattern recognition (GC/PR) analysis is a powerful tool for investigating complicated biological problems. Clustering, mapping, and principal component modelling are necessary to analyze large chromatographic data sets and to seek meaningful relationships between chemical constitution and biological variables. We have applied GC/PR to the problem of deciphering the complex chemical messages of Camponotus floridanus (a carpenter ant) and have learned that GC traces of soaks obtained from the carpenter ants are characteristic of their colony of origin, social caste, and social experience. In this study gas chromatographic data obtained from 119 red carpenter ants was analyzed using principal component analysis and the FCV clustering algorithm.
