The encoding of individual identity in dolphin signature whistles : how much information is needed? [PDF]

, 2013
Bottlenose dolphins (Tursiops truncatus) produce many vocalisations, including whistles that are unique to the individual producing them. Such “signature whistles” play a role in individual recognition and maintaining group integrity.

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

The vocal imitation of bottlenose dolphin (Tursiops truncatus) signature whistles: their use in vocal matching interactions and their role as vocal labels [PDF]

, 2012
The bottlenose dolphin uses vocal learning to develop its own unique acoustic signal. This signal encodes the identity of the signaller, and is known as the animal’s signature whistle.

Concentration of mercury and selenium in tissues of five cetacean species from Croatian coastal waters [PDF]

Archives of Biological Sciences, 2015
Mercury (Hg) and selenium (Se) concentrations were measured in muscle, liver, kidney, spleen and lung tissues of five cetacean species, three dolphin (Stenella coeruleoalba, Tursiops truncatus and Grampus griseus) and two whale species ...

Fishing Activity Affected Odontocete Cetacean Distribution in a Marine Protected Area in the East China Sea

Integrative Zoology, EarlyView.
Spatiotemporal distribution of odontocete cetaceans within China's Jiushan Archipelago National Nature Reserve was investigated. Fishing vessels significantly reduced both cetacean acoustic detections and feeding activity, whereas gillnets selectively suppressed cetacean feeding behavior without affecting overall cetacean detection rates.

Evolutionary Mechanisms of Coagulation Factors in Cetaceans During Aquatic Adaptation

Integrative Zoology, EarlyView.
Compared with Bos taurus, T. truncatus showed shorter prothrombin time and thrombin time but prolonged activated partial thromboplastin time, indicating pathway‐specific remodeling of coagulation. Evolutionary analyses identified 18 positively selected genes and accelerated F11 evolution, while functional assays revealed increased coagulation factor ...

Sex, Age, and Individual Differences in Bottlenose Dolphins (Tursiops truncatus) in Response to Environmental Enrichment [PDF]

Animal Behavior and Cognition, 2015
Application of environmental enrichment, as a means to successfully decrease undesired behaviors (e.g., stereotypic) and improve animal welfare, has been documented in a variety of zoological species.

Maximizing eDNA detections of rare marine organisms: A case study of a delphinid species

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) is an emerging tool for surveying marine organisms. Advances in molecular assay designs and bioinformatic methods provide new opportunities for detecting rare species; however, overcoming methodological challenges of rare species detection remains an important obstacle for the widespread deployment of eDNA methods for ...

Is Gillnet Prey Subsidizing Ontogenetic Diet Shifts and Early Weaning in Common Coastal Bottlenose Dolphins From the Southwestern Gulf of Mexico?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Artisanal gillnet fisheries can concentrate prey and provide incidental food subsidies to marine predators, but their effects on early‐life foraging behavior and demography remain poorly resolved. The Alvarado bottlenose dolphin population that lives off the coast of Veracruz, Mexico, is well known for having chronic, frequent, and recurring ...

Population genetics of bottlenose dolphins (Tursiops truncatus) from an Anglo-Saxon archaeological site in comparison with modern populations. [PDF]

, 2004
Bottlenose dolphins {Tursiops truncatus) exhibit a cosmopolitan distribution, being found in temperate and tropical oceans throughout the world. Members of this species in the waters surrounding Britain are the most northerly populations and show a ...
