Behavioral determinations of thresholds for n-butyl acetate and nbutyl alcohol in the tiger salamander (Ambystoma tigrinum)

Two groups of tiger salamanders (Ambystoma tigrinum) were conditionedto respond to odorant-air mixtures of n-butyl acetate (8.9 x10^–5M) or n-butyl alcohol (6.7 x l0^–5M). They werethen given tests with various concentrations of the trainingodorants presented using a temporal forced-choice method ofascending limits. Results showed that reliable responses toodorant-air presentations were obtained with concentrationsof n-butyl acetate above 2.4 x l0^–7M and with concentrationsof n-butyl alcohol above 8.5 x 10^–8M. These results arein substantial agreement with previous dectrophysiological findings.
