Hybridization in the wild between Tursiops truncatus (Montagu 1821) and Delphinus delphis (Linnaeus 1758) [PDF]

, 2019
A case of intergeneric hybridization in the wild between a female bottlenose dolphin (Tursiops truncatus) and a short-beaked common dolphin (Delphinus delphis), considered members of 'vulnerable' and 'endangered' subpopulations in the Mediterranean ...

INTRACEREBRAL HEMORRHAGE IN A BOTTLENOSED DOLPHIN (Tursiops truncatus) [PDF]

Journal of Wildlife Diseases, 1977
A neurologic condition closely resembling a common human disease, hypertensive intracerebral hemorrhage, is described in a captive dolphin. Motor deficits and the possibiltiy that behavioral changes resulted in the animal's being attacked and driven off by its herdmates, are discussed in terms of damage resulting from the hemorrhagic lesion.

Behavioural laterality in foraging bottlenose dolphins (Tursiops truncatus) [PDF]

Royal Society Open Science, 2019
Lateralized behaviour is found in humans and a wide variety of other species. At a population level, lateralization of behaviour suggests hemispheric specialization may underlie this behaviour.

Bottlenose dolphins (Tursiops truncatus) do also cast neutrophil extracellular traps against the apicomplexan parasite Neospora caninum

International Journal for Parasitology: Parasites and Wildlife, 2017
Neutrophil extracellular traps (NETs) are web-like structures composed of nuclear DNA decorated with histones and cytoplasmic peptides which antiparasitic properties have not previously been investigated in cetaceans.

Why do dolphins form mixed-species associations in the Azores ?

, 2008
Mixed-species associations are temporary associations between individuals of different species that are often observed in birds, primates and cetaceans.

Acoustic behavior of melon-headed whales varies on a diel cycle. [PDF]

, 2015
Many terrestrial and marine species have a diel activity pattern, and their acoustic signaling follows their current behavioral state. Whistles and echolocation clicks on long-term recordings produced by melon-headed whales (Peponocephala electra) at ...

The Development of Social Play in Bottlenose Dolphins (Tursiops truncatus) [PDF]

Animal Behavior and Cognition, 2014
For the young of many species, social play is an important aspect of development. Previous research has shown that bottlenose dolphin calves engage in social play early in life.

A case study of monofilament line entanglement in a common bottlenose dolphin (Tursiops truncatus): entanglement, disentanglement, and subsequent death

BMC Veterinary Research, 2020
Background Free-ranging common bottlenose dolphins (Tursiops truncatus) can become entangled in fishing line and other marine debris. Infrequently, dolphins can be successfully disentangled, released back into the wild, and later examined postmortem to ...

Temporal changes in the dietary niche of sympatric seals provides insight into the role of competition in population declines

Oikos, EarlyView.
Competition theory suggests that interspecific prey competition can result in changes to the dietary niche, but obtaining timeseries of data from sympatric species experiencing temporal variation in competition is challenging. Scotland is an important area for two species of seals, but over the past 20 years, populations of harbour seals Phoca vitulina
