Dear colleagues,
I am delighted to share with you my latest study for a better understanding of
dolphin vocal communication and social behaviour:
Diaz Lopez, B. Context-dependent and seasonal fluctuation in bottlenose dolphin
(Tursiops truncatus) vocalizations. Animal Cognition (2022).

AbstractA fundamental question in animal behaviour is the role of vocal
communication in the regulation of social interactions in species that organise
themselves into social groups. Context dependence and seasonality in
vocalizations are present in the communication of many species, although very
little research has addressed this dependence in marine mammals. Thestudy
presented here examined variations in the rate at which free-ranging dyads of
bottlenose dolphins emit social-signals in an effort to better understand the
relationship between vocal communication and social context. The results
demonstrate that changes in the social-signal production in bottlenose dolphins
are related to the sex of the partner, mating season and social affiliation
between the components of the dyad. In a context of foraging behaviour on the
same feeding ground, mixed (male–female) dyads were found to emit more pulsed
burst sounds during the mating season. Another relevant aspect of the study
seems to be the greater production of agonistic social-signals in the dyads
formed by individuals with a lower degreeof social affiliation. Overall, this
study confirms a clear relationship between dyad composition and
context-specific social-signals that could reflect the motivational state of
individuals linked to seasonal changes in vocal behaviour.
