Exploration of Horizontal Information Transmission through Social Learning in Juvenile Atlantic Spotted Dolphins (Stenella frontalis) [PDF]
Although vertical (mother-to-offspring) information transfer has been reported in dolphins, it is unclear whether horizontal information transfer takes place between peers of non-parental individuals.

Trophic relationships and habitat preferences of delphinids from the southeastern Brazilian coast determined by carbon and nitrogen stable isotope composition. [PDF]
To investigate the foraging habitats of delphinids in southeastern Brazil, we analyzed stable carbon (δ(13)C) and nitrogen (δ(15)N) isotopes in muscle samples of the following 10 delphinid species: Sotalia guianensis, Stenella frontalis, Tursiops ...

Diagnosing gastric ulcers in bottlenose dolphins (Tursiops sp.) using gastroscopy and cytology
Gastroscopy remains the most accurate method for diagnosing gastric ulcers in bottlenose dolphins (Tursiops sp.). Of the cytological parameters (pH, white blood cells, epithelial cells, basal cells and fluid colour), measured from the gastric fluid of eight dolphins, none were significantly related to the presence or severity of gastric ulcers ...
