“…Studies of signature whistles have most often analyzed captive or temporarily captured bottlenose dolphins (but see Cook, Sayigh, Blum, & Wells, 2004). Atlantic spotted dolphins have a different ecological niche, in terms of feeding strategies and diet, group size, physical size, and home range of the sexes, as compared to bottlenose dolphins (spotted: Herzing & Johnson, 1997;bottlenose: Wells & Scott, 1999). While both species may use signature whistles for cohesion and reunions, these ecological dissimilarities may result in different pressures for signature whistle development.…”

“…However, the two species have different life histories, such as dispersal patterns and foraging strategies (spotted: Herzing & Johnson, 1997;bottlenose: Wells & Scott, 1999). We investigated whether the signature whistles of male Atlantic spotted dolphin calves are more likely to be similar to the signature whistles of their mothers, as previous research has found with bottlenose dolphins (Sayigh et al, 1990(Sayigh et al, , 1995.…”

-We assessed the degree of similarity between signature whistles of mother and offspring pairs in freeliving Atlantic spotted dolphins (Stenella frontalis). As a means of qualitative evaluation, judges compared the timefrequency contour patterns of signature whistle spectrograms. We also evaluated quantitative measurements of whistle frequency and duration. All five female offspring produced signature whistles that were similar to their mothers' whistles by a least one means of comparison, whereas two of the four male offspring produced signature whistles that were dissimilar from their mothers' by both methods of comparison. However, statistically, male offspring were just as likely to produce signature whistles like their mothers' as female offspring (p = 0.167). We compared whistle similarity between mothers and offspring to the degree of association for each pair. Offspring that most often associated with their mothers when they were four years of age had whistles that were more similar to their mothers' whistles both qualitatively (r(4) = 0.92, p = 0.009) and quantitatively (r(4) = 0.92, p = 0.004). Because signature whistles are developed within a dolphin's first year, our finding likely reflects the level of bond between mother and calf.

“…His study showed that aggression was more the result of an object-oriented play than aggressive behaviour displayed by one species competing for food, mate, or space. In the western edge of Great Bahama Bank, Herzing et al (2003) observed interspecific interactions between Atlantic spotted dolphins (Stenella frontalis ) and bottlenose dolphins, with male spotted dolphins displaying dominant mounting behaviour towards bottlenose dolphin males. In Hawaiian waters, Psarakos et al (2003) also observed aggressive behaviour between sympatric spinner and spotted dolphins.…”

Interspecific associations between two or more species of the family Delphinidae have been reported by many scientists, but the sympatric ecology of such dolphin associations has not been studied in great detail. A few field investigations have been conducted on this subject in different parts of the world on species such as bottlenose dolphins (Tursiops spp.), short-beaked common dolphins (Delphinus delphis ), and killer whales (Orcinus orca ). Sympatric dolphins seem to use different strategies to co-exist when resources appear to be limited, including dietary divergence (different prey preference, slightly diverse diet, different feeding time) and/or different habitat use (shallow versus deep waters, flat areas versus submarine canyons and escarpments, different travel routes). This paper presents a review of some well-studied dolphin species found in sympatry and discusses the nature of habitat and resource partitioning as well as studies on aggressive behaviour displayed by species living in the same habitat.

-Although vertical (mother-to-offspring) information transfer has been reported in dolphins, it is unclear whether horizontal information transfer takes place between peers of non-parental individuals. We hypothesized that horizontal information transmission takes place within juvenile social play-forage subgroups and within pairs of juveniles in the form of social learning, as a way for older juveniles to contribute to the further development of younger juveniles' foraging skills. Since 1985, a long-term study in the Bahamas has involved the collection of underwater videos and sound recordings on the social structure of a resident community of free-ranging Atlantic spotted dolphins Stenella frontalis. Foraging behaviors of juvenile dolphins were analyzed in 24 independent foraging events recorded on video from 1994 to 2013. Forty-nine juveniles in total were observed, including eight individually identified juveniles foraging alone, eight individually identified juveniles foraging in pairs, and 33 juveniles foraging in eight subgroups of three or more dolphins. The comparison of older juveniles' behavior against younger juveniles' behavior in juvenile play-forage subgroups suggested the potential for horizontal transmission of information about prey location. However, we found no direct evidence for social learning or of teaching in pairs. This new information about wild Atlantic spotted dolphin social structure is a starting point in horizontal information transmission research and is important in terms of cognitive processes and welfare implications.
