Magnetoreception, meaning the perception of mag-netic fields, is supposed to play an important role for orientation/ navigation in some terrestrial and aquatic species. Although some spatial observations of free-ranging cetaceans' migration routes and stranding sites led to the assumption that cetaceans may be sensitive to the geomagnetic field, ex...

Bottlenose dolphins are highly social cetaceans with an extensive sound production including clicks, burst-pulsed sounds, and whistles. Some whistles, known as signature whistles, are individually specific. These acoustic signatures are commonly described as being emitted in contexts of stress during forced isolation and as group cohesion calls. In...

Bottlenose dolphins (Tursiops truncatus) are highly social odontocetes that live in a fission-fusion society and demonstrate production of a varied sound repertoire, including clicks, whistles, and burst-pulsed sounds, as well as a diverse behavioral repertoire. To better understand the species’ behavior, it is necessary to compare visual and acous...

Bottlenose dolphins are social cetaceans that strongly rely on acoustic communication and signaling. The diversity of sounds emitted by the species has been structurally classified into whistles, clicks and burst-pulsed sounds. Although click sounds and individually-specific signature whistles have been largely studied, not much is known about non-...

Synchronous behaviours occur when two or more animals display the same behaviour at the same time. However, the mechanisms underlying this synchrony are not well understood. In this study, we carried out an experiment to determine whether or not Bottlenose dolphins use acoustic cues when performing a known synchronised exercise. For this, we record...

Exploratory behaviorincludes all the actions that an animal performs to obtain information about a new object, environment,or individual through using its different senses of perception. Here, we studied the development of the exploratory behavior of a bottlenose dolphin (Tursiops truncatus) calf aged from 39 to 169 days by investigating its acoust...

Bottlenose dolphins are highly social cetaceans that strongly rely on acoustic communication and signaling. The diversity of sounds emitted by the species has been structurally classified in whistles, clicks and burst-pulsed sounds, with some whistles called « signature whistles » that are used as cohesion calls. During this thesis, we developed an...

Sensory perception is the process by which an organism detects and interprets information from the external world by means of sensory receptors. Its study is of particular interest in cetaceans due their particular evolutionary history for returning from terrestrial to aquatic life. In order to test three different sensory modalities in these anima...

The respiratory rate is a variable commonly used to measure disturbances caused by human activities on cetaceans. Here a feasibility study of respiratory changes in response to two potential stressors (tagging events and vessels noise) was made with a registry from 12 individuals belonging to a population of short-finned pilot whales in Tenerife an...
