Echoic Object Recognition by the Bottlenose Dolphin [PDF]
Comparative Cognition & Behavior Reviews, 2008 Object recognition, essential to many animals, often occurs underwater and in poor visibility conditions for bottlenose dolphins. Bottlenose dolphins can use sound through their ability to echolocate in order to recognize objects. Echoic object recognition is an unusual faculty that offers rich research opportunities and is the focus of this article ...

Personality structure in bottlenose dolphins (Tursiops truncatus). [PDF]
Journal of Comparative Psychology, 2021 Comparative studies can help identify selective pressures that contributed to species differences in the number and composition of personality domains. Despite being adapted to an aquatic lifestyle and last sharing a common ancestor with primates some 95 million years ago, bottlenose dolphins (Tursiops truncatus) resemble nonhuman primate species in ...

Alkenones in oceanic odontocetes as a potential proxy of environmental water temperature
Ecological Indicators, 2021 The alkenones C37:2 and C37:3 are produced exclusively by some haptophyte species. Their relative proportion (Uk’37 index) may be used to infer the water temperature where the synthesising haptophyte lived.

Trawling and bottlenose dolphins' social structure [PDF]
Proceedings of the Royal Society of London. Series B: Biological Sciences, 2001 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 ...

Marine Biology, 2017 The evolutionary processes that shape patterns of diversity in highly mobile marine species are poorly understood, but important towards transferable inference on their effective conservation. In this study, bottlenose dolphins (Tursiops sp.) are studied

Unihemispheric sleep deprivation in bottlenose dolphins [PDF]
Journal of Sleep Research, 1992 SUMMARY Unihemispheric and bihemispheric sleep deprivation were performed in bottlenose dolphins. One brain hemisphere was capable of being deprived of delta (0.5‐3.0 Hz) sleep in the former condition. Here, an increase in sleep pressure was observed during sleep deprivation in the deprived hemisphere.

Ecology and Evolution, 2017 Due to their worldwide distribution and occupancy of different types of environments, bottlenose dolphins display considerable morphological variation. Despite limited understanding about the taxonomic identity of such forms and connectivity among them ...

Frontiers in Marine Science, 2021 Although previous studies have described progesterone profiles during pregnancy in the bottlenose dolphin (Tursiops truncatus), most of these focused on normal pregnancy (NORM) or compared NORM to only one or two abnormal pregnancy types, such as ...

Tour boats affect the activity patterns of bottlenose dolphins (Tursiops truncatus) in Bocas del Toro, Panama [PDF]
PeerJ, 2020 Bottlenose dolphins (Tursiops truncatus) of the Bocas del Toro archipelago are targeted by the largest boat-based cetacean watching operation in Panama. Tourism is concentrated in Dolphin Bay, home to a population of resident dolphins.
