Abstract

Elephants’ flexible cognitive abilities and fission-fusion societies make them an excellent study species to investigate individual social recognition. Despite the substantial role chemical cues play in elephant social communication, there is a considerable lack of research into their chemosensory social recognition, especially in Asian elephants (Elephas maximus). Using two-choice tests, I assessed Asian elephants’ chemosensory ability to discriminate between individuals by both presence and familiarity. I also used a habituation-discrimination paradigm to assess individual recognition in elephants by determining whether elephants integrate odor cues (i.e., urine and feces) to form multi-cue representations of individuals. Responses between samples were not significantly different in the two-choice tests, failing to provide evidence that Asian elephants can discriminate between these conditions. While the habituation-discrimination series with unfamiliar elephants indicated subjects were not matching unfamiliar urine and feces through individually distinct components present in both odor types, the series with familiar elephants failed to support the use of individual representations. Though these results were inconclusive due to methodological limitations, they lend important insights informing the methodology of future studies as well as new directions to investigate individual representation.
