“…There are two general methods for analyzing the organizational structure within sequences of events: chi-square tests (X 2 ) and information theory techniques (Chatfield and Lemon, 1970). These methods are similar (see review by Chatfield and Lemon, 1970), although X 2 tests allow for more detailed investigation of specific associations of calls within bouts.…”

“…Information theory has been utilized by a number of studies looking at sequences of events (e.g., Shannon, 1948;Chatfield and Lemon, 1970;McCowan et al, 1999;Riesch et al, 2008), including the structure of humpback whale song (Suzuki et al, 2006;Miksis-Olds et al, 2008). Information theory investigates the degree of diversity and organizational structure in a sequence of events by quantifying the amount of entropy that is lost in a system through knowledge of repertoire diversity (zero-order approximation of entropy), the frequency of occurrence of all behaviors (e.g., words or calls) in a repertoire (first-order approximation of entropy), and the conditional probabilities for which behaviors are combined (second-, third-, fourth-order, etc., approximation of entropy or n À 1 order Markov chain) (Shannon, 1948).…”

The use of stereotyped calls within structured bouts has been described for a number of species and may increase the information potential of call repertoires. Humpback whales produce a repertoire of social calls, although little is known about the complexity or function of these calls. In this study, digital acoustic tag recordings were used to investigate social call use within bouts, the use of bouts across different social contexts, and whether particular call type combinations were favored. Call order within bouts was investigated using call transition frequencies and information theory techniques. Call bouts were defined through analysis of inter-call intervals, as any calls within 3.9 s of each other. Bouts were produced significantly more when new whales joined a group compared to groups that did not change membership, and in groups containing multiple adults escorting a female and calf compared to adult only groups. Although social calls tended to be produced in bouts, there were few repeated bout types. However, the order in which most call types were produced within bouts was non-random and dependent on the preceding call type. These bouts appear to be at least partially governed by rules for how individual components are combined.

“…Although rarely applied to the study of animal communication [4,5,[22][23][24][25] and references therein], information theory has generally been applied to the communication in social species. Undoubtedly, social species have the potential to have an immediate impact on researchers interested in animal communication because of the evident need that grouped individuals have to communicate amongst them.…”

Abstract:The outstanding levels of knowledge attained today in the research on animal communication, and the new available technologies to study visual, vocal and chemical signalling, allow an ever increasing use of information theory as a sophisticated tool to improve our knowledge of the complexity of animal communication. Some considerations on the way information theory and intraspecific communication can be linked are presented here. Specifically, information theory may help us to explore interindividual variations in different environmental constraints and social scenarios, as well as the communicative features of social vs. solitary species.

“…Due to this limitation, few investigators (e.g. Chatfield and Lemon, 1970;Hailman and Ficken, 1986;Hailman et al, 1985Hailman et al, , 1987Ficken et al, 1994;Hailman, 1994;Da Silva et al, 2000) have been able to apply information measures to sequential signaling as a means for deciphering the structure and organization of communication systems at the individual, population, or species level.…”

Using information theory to assess dynamics, structure, and organization of crayfish agonistic repertoire

Information theory measures provided useful quantitative tools for describing the transfer of information in interacting pairs of the eastern white-river crayfish, Procambarus acutus acutus, and furnished hints for deciphering the dynamics, structure, and organization of the agonistic repertoire in this species. As a confirmation of the predictive and heuristic potentials of the theory, results suggested hypotheses on the mechanisms underlying the formation and maintenance of dominance hierarchies in crayfish and indicated the directions that future developments of the research should follow.
