abstract = {Comparative analysis of nonhuman animal communication systems and their complexity, particularly in comparison to human language, has been generally hampered by both a lack of sufficiently extensive data sets and appropriate analytic tools. Information theory measures provide an important quantitative tool for examining and comparing communication systems across species. In this paper we use the original application of information theory, that of statistical examination of a communication system’s structure and organization. As an example of the utility of information theory to the analysis of animal communication systems, we applied a series of information theory statistics to a statistically categorized set of bottlenose dolphinTursiops truncatus, whistle vocalizations. First, we use the first-order entropic relation in a Zipf-type diagram (Zipf 1949Human Behavior and the Principle of Least Effort) to illustrate the application of temporal statistics as comparative indicators of repertoire complexity, and as possible predictive indicators of acquisition/learning in animal vocal repertoires. Second, we illustrate the need for more extensive temporal data sets when examining the higher entropic orders, indicative of higher levels of internal informational structure, of such vocalizations, which could begin to allow the statistical reconstruction of repertoire organization. Third, we propose using ‘communication capacity’ as a measure of the degree of temporal structure and complexity of statistical correlation, represented by the values of entropic order, as an objective tool for interspecies comparison of communication complexity. In doing so, we introduce a new comparative measure, the slope of Shannon entropies, and illustrate how it potentially can be used to compare the organizational complexity of vocal repertoires across a diversity of species. Finally, we illustrate the nature and predictive application of these higher-order entropies using a preliminary sample of dolphin whistle vocalizations. The purpose of this preliminary report is to re-examine the original application of information theory to the field of animal communication, illustrate its potential utility as a comparative tool for examining the internal informational structure of animal vocal repertoires and their development, and discuss its relationship to behavioural ecology and evolutionary theory.},

abstract = {The immune repertoire is characterized by a complex and dynamic organization. Here I suggest, based on the presence of well-defined immune reactivity patterns (RP) analyzed using a linguistic analogy, that the B cell repertoires could possess a fractal structure. A simple estimation method of the fractal dimension (D) for a given immune B repertoire was developed, and D demonstrated to be an useful tool to define what complexity is regarding the immune repertoire, and to evaluate the complexity level of the immune B repertoire among age-structured groups of mice sensitized with the hemagglutinin (HA) molecule of influenza virus. Also, since a fractal-linguistic point of view, considerations are made about the ontogeny, connectivity, chaotic regimes, and size of the immune repertoire. Fractal analysis indicates that the immune repertoire shows a Zipf-like scaling behavior, a statistical property of natural languages. This result suggests that immune repertoire is structured like a powerful language.},

abstract = {The Zipf law, an approach to analyzing linguistic texts, was applied to study the Cytotoxic T Lymphocytes (CTL) repertoire, one of the major components of the immune system. A Zipf-scaling behavior was observed in those CTL repertoires obtained in normal or conventional mice. In contrast, CTL repertoires from irradiated chimeric animals, showed a non-scaling statistical behavior when tested by the Zipf analysis,suggesting that normal repertoires work like a structured biological language. The fractal dimension (D) was derived from the Zipf plots, and correlates well with the nature of the repertoires: high, D > 0.8, in conventional mice. Non-fractal, D > 1, in chimeric animals, and low, D < 0.3, in athymic mice. Then, D seems to be an useful tool to characterize the current status of the immune system.},

abstract = {Chick-a-dee calls of the Mexican Chickadee (Parus sclateri) are composed of combinations of three common note types (A, C and D) and one very rare type (B). Calls have the invariant sequence of notes A-B-C-D, where any note type may be omitted, given once or repeated a variable number of times before transiting to the next type. The B and C notes are phonologically similar to the B and C notes of chick-a-dee calls of the Black-capped Chickadee (P. atricapillus), but the A note is markedly different and the D note somewhat different from equivalent notes of the congener. A total of 2,071 calls recorded yielded 60 different call types, and Zipf-Mandelbrot plots show that the call system is "open"; as the sample size is increased new call types will be found without demonstrable bound. In relatively undisturbed contexts (with mate on territory, in fall flocks, alone in fall) birds gave mainly [A][D] calls with lesser numbers of [A] and [C] calls, where brackets indicate variable repetition of note types. In disturbed contexts (mobbing plastic Great Horned Owl, mobbing speaker playing calls of the Northern Pygmy-Owl, observer sitting under the nest cavity) the birds gave more [C] calls with [A][C] as well. In the longest mobbing session to owl calls, birds gave mainly [A] calls when approaching, switched to [C] calls while flying about the speaker, and then resumed [A] calls and moved off when the playback was stopped. Outside of human language, this is the second truly combinatorial system of vocal communication found in animals, the first being chick-a-dee calls of the Black-capped Chickadee. This study provides the first data substantiating quantitative differences in calls from different contexts, an important step toward understanding what kinds of information combinatorial chick-a-dee calls encode.},

abstract = {Examined the vocalizations of 2 wild-caught black-lored tits. It was found that the Ss gave chick-a-dee-like calls in response to a stuffed owl. The tit used combinations of 4 note types to create 65 different call types. The repertoire of call types had the language-like property of openness to formation of new call types without limit. Calling under constant stimulus conditions changed unidirectionally during the course of mobbing, with the 4 note types replacing each other in calls, as time progressed. Thus, the tit had a constrained type of permuted order of note types, which enlarged the potential for call variety and closely resembled properties of language.},

abstract = {The problem of the degree of complexity and semantic capabilities of the acoustic communicative system in bottlenose dolphins has been under discussion for over a quarter of a century, ever since John Lilly published his book ``Man and Dolphin'' (Lilly, 1962). Nowadays, there is an abundance of literature, with different viewpoints, but no consensus has been reached so far among researchers. The problem proved to be very complicated, both methodologically and experimentally, while the methods used turned-out to be labor-consuming and, on the whole, inefficient; all kinds of straightforward attacks failed. Meanwhile, one can try and assess potential capabilities of communicative system by analysing dolphins' mechanisms ensuring its productivity, i.e. the creation of signals and messages in amounts nessesary for communication. These mechanisms ensure the encoding of information and, in accordance with the theory, their functioning, in this way or other, affects the structure of signals and their sequences, in other words, it affects the organization of communicative system.},

The 2nd feature suggests semantic properties of D-notes. A chicakadee call is thought to resemble a natural sentence of spoken human language.},
