“…The most detailed information available in the literature concerns the recognition of vocal signals by birds (e.g., Falls, 1982). Many studies have demonstrated the ability of nonhuman mammals to discriminate individuals by the use of chemicals (e.g., Halpin, 1980Halpin, , 1986Brown et al, 1990;Hurst et al, 2001). Particularly in the last few years, considerable effort has been directed at defining in vertebrates the processes of identification and recognition (Beecher, 1989): at the cognitive analysis level, questions have been addressed on the nature of individual representation exhibited by a handful of vertebrate taxa and on the evolutionary pathways leading to high-order knowledge about individuals (e.g., Johnston and Bullock, 2001).…”

Unraveling the Nature of Individual Recognition by Odor in Hermit Crabs

Abstract-Individual recognition is a key element in the social life of many invertebrates. However, most studies conducted so far document that several species are capable of a Bbinary^discrimination among conspecifics, but not of a Btrue individual recognition.^Our objective was to learn more about the mechanisms that underlie individual recognition by odor in hermit crabs by individuating some of its properties. Using Pagurus longicarpus Say 1817 as a model species, we conducted four series of experiments in which the response of every test crab (the Breceiver^) to the different odor treatments (emitted by a Bsender^) was evaluated from its investigative behavior toward an empty, high-quality shell. After having excluded the possibility that crabs chemically recognize familiar/unfamiliar shells and /or shells of high/low quality, we explored whether the receivers discriminate odors from two familiar senders and whether this discrimination also occurs with unfamiliar crabs. We also asked whether crabs form an association between the odor of a familiar sender and some of its relevant attributes, i.e., rank, size, and shell quality. Finally, the shells inhabited by familiar individuals were manipulated to modify the association between odor and shell quality. Results showed that: (1) there is no odor specific of a rank; (2) individual crabs discriminate their own odor from the odor of other individuals; (3) they can chemically discriminate between larger crabs inhabiting higher-quality shells and smaller crabs inhabiting lower-quality shells, provided that these crabs are familiar to them; (4) they associate the odor of an individual crab with the quality of the shell it inhabits; and (5) this association quickly changes when social partners switch to shells of different quality. These results indicate that the nature of chemical recognition in P. longicarpus is more refined than a simple binary 0098-0331/05/1200-2877/0 # 2005 Springer Science + Business Media, Inc. 2877Journal of Chemical Ecology, Vol. 31, No. 12, December 2005 DOI: 10.1007/s10886-005-8400-5 * To whom correspondence should be addressed.

The receiver appears able to associate a type of information from the sender with memories of past experiences, therefore suggesting the hermit crab's potential for relatively high-order knowledge about conspecifics.
