Roaring to Go: Engagement With Positive Reinforcement Training as a Valid and Reliable Indicator of Positive Welfare in Zoo Big Cats

open access: yesZoo Biology, EarlyView.
A figure summarising the information conveyed by the abstract in graphical form ABSTRACT Engagement with positive reinforcement training is a non‐invasive, easily recorded, and valid indicator of welfare in captive bottlenose dolphins. However, despite the ubiquitousness of training programs in zoo‐housed mammals in accredited zoos, this metric has yet

Novel prey item identified for estuarine bottlenose dolphins (Tursiops erebennus) in the Southeastern United States

open access: yesScientific Reports
The community of Tamanend’s bottlenose dolphins (Tursiops erebennus) inhabiting the St. Johns River (SJR) in Jacksonville, Florida, is affected by a suite of challenges including dredging, vessel traffic, fishing gear entanglements, pollution, and ...

Vocal universals and geographic variations in the acoustic repertoire of the common bottlenose dolphin

open access: yesScientific Reports, 2021
Acoustical geographic variation is common in widely distributed species and it is already described for several taxa, at various scales. In cetaceans, intraspecific variation in acoustic repertoires has been linked to ecological factors, geographical ...

Future Challenges and Opportunities for the Viability of Animal Populations in Zoos and Aquariums

open access: yesZoo Biology, EarlyView.
ABSTRACT Maintaining sustainable animal populations is fundamental to zoo and aquarium missions in education, visitor engagement, entertainment, scientific advancement, public health and wellbeing, advocacy, and conservation impact. Yet, sustaining viable populations remains a persistent challenge.

Evidence for distinct coastal and offshore communities of bottlenose dolphins in the north east Atlantic.

open access: yesPLoS ONE, 2015
Bottlenose dolphin stock structure in the northeast Atlantic remains poorly understood. However, fine scale photo-id data have shown that populations can comprise multiple overlapping social communities.

Modeling Skin Mark Temporal Variations to Estimate the Sex of Delphinids with Low Sexual Dimorphism: Implications for Management and Conservation

open access: yesIntegrative Zoology, EarlyView.
This work aimed to apply the principles of skin mark analysis to a cetacean species to build a sex‐discrimination model exclusively based on photographic material. Relevant differences between sexes emerged in markings, with males presenting more social, aggression‐related, and fishing‐related marks overall, and a stronger tendency of mark accumulation

Genetic characterisation and social structure of the East Scotland population of bottlenose dolphins (Tursiops truncatus) [PDF]

open access: yes, 2010
The Eastern Scottish population of bottlenose dolphins (Tursiops truncatus) is the northernmost population of this species. The resident core of this population consists of 120 to 150 different individuals.

Acoustic behaviour of Risso's dolphins, Grampus griseus, in the Canary Islands, Spain [PDF]

open access: yes, 2013
The Risso's dolphin (Grampus griseus) is a poorly studied species, particularly with respect to its acoustic behaviour. The little we know about Risso's dolphin acoustics shows that they are an interesting case study given that they combine acoustic ...

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

open access: yesIntegrative 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 ...

Interspecies Retinal Diversity and Optic Nerve Anatomy in Odontocetes

open access: yesAnimals, 2023
Throughout evolution, odontocete vision has had to readapt to the aquatic environment, which has had far-reaching effects on ocular anatomy and neurology.
