R code and Y-tube olfactometer data from: Floral and bird excreta semiochemicals attract western carpenter ants

This data set described here is supplementary to a published paper titled: “Floral and bird excreta semiochemicals attract western carpenter ants”. Few studies have examined if ants use odours to locate food resources. Using Western carpenter ants, Camponotus modoc, as a model organism, we tested the hypotheses that ants would be generally attracted to all food resources (aphid honeydew, floral, carrion and animal (bird) excreta) tested. As floral resources have overlapping odourant chemicals in their odours, we further hypothesized ants would be attracted to shared semiochemicals between floral resources. The full methodology, results and their interpretation can be found in the publication.
