Quantitative tools for comparing animal communication systems: Information theory applied to bottlenose dolphin whistle repertoires
Article Abstract:
Comparative analysis of animal communication systems, particularly in comparison to human language, has been restricted by the lack of extensive data sets and suitable analytic tools. Information theory has been applied to animal communication and it is suggested that it can be applied to animal communication systems at the level for which the tool was originally designed. Dolphin whistle vocalizations were analyzed using information theory measures, providing useful tools to evaluate and compare the structure of animal communicative repertoires in relation to behavioural ecology and evolutionary theory.

Barking in domestic dogs: Context specificity and individual identification
Article Abstract:
Univariate and multivariate analyses of bark vocal parameters were conducted to determine whether dog barks could be divided into subtypes based on context. Discriminant analysis reveal that dog barks could be divided into different subtypes based on context even within individual dogs, and that dogs could be identified by their bark spectrograms despite the context of the bark.

The fallacy of 'signature whistles' in bottlenose dolphins: a comparative perspective of 'signature information' in animal vocalizations
Article Abstract:
Bottlenose dolphins are isolated and their whistles are recorded in order to determine whether or not they have a unique sound for identification. Whistle frequencies are graphed, analyzed, and categorized, showing that signature whistles are not produced in isolation.
