Combining different stereotyped vocal signals into specific sequences increases the range of information that can be transferred between individuals. The temporal emission pattern and the behavioral context of vocal sequences have been described in detail for a variety of birds and mammals. Yet, in cetaceans, the study of vocal sequences is just in its infancy. Here, we provide a detailed analy...
peak flow readings begins and hence this measurement is of less diagnostic value. Technically it is quite easy to alter the whistle so that more accurate readings are obtained above 300 1./min., but when this is done the performance of the whistle is less discriminating for small variations at low flow rates. Overestimation of the peak expiratory flow rate by the whistle is negligible (2%). The...
This paper handles the issue of identifying the whistle of a dolphin in the presence of noise. When a recorded underwater signal containing other sounds is given to a system, it detects and identifies the presence of dolphin whistle. Analyzing the extracted underwater sounds gives meaningful information about the environment. Also, the presence of a particular underwater species and their behav...
We examine the interplay between social norms and the enforcement of laws. Agents choose a behavior (e.g., tax evasion, production of low-quality products, corruption, harassing behavior, substance abuse, etc.) and then are randomly matched with another agent. There are complementarities in behaviors so that an agent’s payoff decreases with the mismatch between her behavior and her partner’s, a...
We show that dolphin whistle types tend to be used in specific behavioral contexts, which is consistent with the hypothesis that dolphin whistle have some sort of “meaning”. Besides, in some cases, it can be shown that the behavioral context in which a whistle tends to occur or not occur is shared by different individuals, which is consistent with the hypothesis that dolphins are communicating ...
The developments of marine observatories and automatic sound detection algorithms have facilitated the long-term monitoring of multiple species of odontocetes. Although classification remains difficult, information on tonal sound in odontocetes (i.e., toothed whales, including dolphins and porpoises) can provide insights into the species composition and group behavior of these species. However,...
