Decades-long social memory in bottlenose dolphins.
Long-term social memory is important, because it is an ecologically relevant test of cognitive capacity, it helps us understand which social relationships are remembered and it relates two seemingly disparate disciplines: cognition and sociality. For dolphins, long-term memory for conspecifics could help assess social threats as well as potential social or hunting alliances in a very fluid and ...
متن کاملVocalizations in social interactions among captive dolphins
In order to understand the role of vocalization in dolphin social interactions, we need to know which animals are engaged with which other animals, what activity they are engaged in, and which animals are vocalizing. In this poster we describe our efforts to address the linked problems of identifying individual animals and identifying which animal produced which sounds. Solving these problems i...
متن کاملPhonation behavior of cooperatively foraging spinner dolphins.
Groups of spinner dolphins have been shown to cooperatively herd small prey. It was hypothesized that the strong group coordination is maintained by acoustic communication, specifically by frequency-modulated whistles. Observations of groups of spinner dolphins foraging at night within a sound-scattering layer were made with a multibeam echosounder while the rates of dolphin sounds were measure...
متن کاملTrawling and bottlenose dolphins' social structure.
Human activities can affect the behaviour of mammals through the modification of habitats, changes in predation pressure or alterations in food distribution and availability. We analysed the association and ranging patterns of 242 individually identified bottlenose dolphins (Tursiops aduncus) in eastern Moreton Bay, Queensland, Australia, and distinguished two separate communities of dolphins. ...
متن کاملThe broadband social acoustic signaling behavior of spinner and spotted dolphins.
Efforts to study the social acoustic signaling behavior of delphinids have traditionally been restricted to audio-range (<20 kHz) analyses. To explore the occurrence of communication signals at ultrasonic frequencies, broadband recordings of whistles and burst pulses were obtained from two commonly studied species of delphinids, the Hawaiian spinner dolphin (Stenella longirostris) and the Atlan...
