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.

The bottlenose dolphin (Tursiops truncatus) faecal microbiota [PDF]

FEMS Microbiology Ecology, 2016
Cetaceans have evolved from herbivorous terrestrial artiodactyls closely related to ruminants and hippopotamuses. Delphinidae, a family included in this order, represent an extreme and successful re-adaptation of mammalian physiology to the marine habitat and piscivorous diet.

The influence of fish farm activity on the social structure of the common bottlenose dolphin in Sardinia (Italy) [PDF]

PeerJ, 2021
In a wide variety of habitats, including some heavily urbanised areas, the adaptability of populations of common bottlenose dolphin (Tursiops truncatus) may depend on the social structure dynamics.

Comparative analysis of three brevetoxin-associated bottlenose dolphin (Tursiops truncatus) mortality events in the Florida Panhandle region (USA).

PLoS ONE, 2012
In the Florida Panhandle region, bottlenose dolphins (Tursiops truncatus) have been highly susceptible to large-scale unusual mortality events (UMEs) that may have been the result of exposure to blooms of the dinoflagellate Karenia brevis and its ...

Spatial and temporal variation in the occurrence of bottlenose dolphins in the Chesapeake Bay, USA, using citizen science sighting data.

PLoS ONE, 2021
Bottlenose dolphins (Tursiops truncatus) are migratory marine mammals that live in both open-ocean and coastal habitats. Although widely studied, little is known about their occurrence patterns in the highly urbanized estuary of the Chesapeake Bay, USA ...

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.

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 ...

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.

Comparisons of Serum Progesterone and Progestagen Concentrations in Normal and Abnormal Bottlenose Dolphin (Tursiops truncatus) Pregnancies

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 ...

Hearing abilities and acoustic signalization of the bottlenose dolphin Tursiops Truncatus with early hearing loss

Frontiers in Marine Science
Common bottlenose dolphins (Tursiops truncatus) are among non-human mammals that possess the ability for vocal production learning, which strongly depends on learning from conspecifics. The hearing sensitivity and acoustic signals of a 4-year-old captive-
