Eavesdropping on dolphins: Investigating the habits of bottlenose dolphins (Tursiops truncatus) through fixed acoustic stations.

PLoS ONE, 2019
This study investigates the bottlenose dolphin (Tursiops truncatus, Montagu 1821) habitat use in the Portofino marine protected area (NW Italy) and adjacent waters, a core area for the dolphins and a highly touristic area in the Mediterranean Sea.

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

Scientific 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 ...

Multi‐Platform Deployments of Low‐Cost Devices for Cetacean Passive Acoustic Monitoring

Remote Sensing in Ecology and Conservation, EarlyView.
Recent advances in affordable, user‐friendly devices offer new opportunities to overcome cost constraints of underwater passive acoustic monitoring (PAM) and expand acoustic data collection. In this study, we deployed low‐cost acoustic recorders and underwater cameras across a range of platforms in the Western Mediterranean, including fishing gear ...

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

Scientific 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 ...

The Greatest Show (Birds) on Earth: Public Presentations and Their Welfare Impacts on Zoo‐Housed Birds

Zoo Biology, EarlyView.
Birds involved in bird shows were compared against non‐show birds regarding show paticipation, behaviour, body score condiiton, and feather condition. Additionally, comparisons between on and off show days as well as before and after the show were made to investigate differences in behaviour and condition. Show birds demonstrated a closer to ideal body

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

PLoS 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

Integrative 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

Interspecies Retinal Diversity and Optic Nerve Anatomy in Odontocetes

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

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 ...

Comparative Genomics and Functional Evidence for Convergent Adaptation to Hypoxia in Mammals

Integrative Zoology, EarlyView.
This study reveals convergent selection in mammals adapted to hypoxia. Functional assays demonstrate that amino acid mutations reduce oxidative stress, attenuate hypoxia‐induced injury, and modulate the hypoxia‐inducible transcription factor (HIF)‐driven hypoxic response.
