Whistle source levels of free-ranging bottlenose dolphins and Atlantic spotted dolphins in the Gulf of Mexico

The Journal of the Acoustical Society of America, 2014
Whistles of bottlenose dolphins (Tursiops truncatus) and Atlantic spotted dolphins (Stenella frontalis) in the eastern Gulf of Mexico were recorded and measured with a calibrated towed hydrophone array. Surveys encountered groups of both bottlenose (N = 10) and spotted dolphins (N = 5).

Echolocation signals of wild Atlantic spotted dolphin (Stenella frontalis)

The Journal of the Acoustical Society of America, 2003
An array of four hydrophones arranged in a symmetrical star configuration was used to measure the echolocation signals of the Atlantic spotted dolphin (Stenella frontalis) in the Bahamas. The spacing between the center hydrophone and the other hydrophones was 45.7 cm.

Primary uterine T-cell lymphoma with metastasis in an Atlantic spotted dolphin (Stenella frontalis), Canary Islands, Spain.

Journal of Wildlife Diseases, 2015
We describe gross, histopathologic, and immunonocytologic features of a primary uterine T-cell lymphoma with multiple metastases in an adult female Atlantic spotted dolphin (Stenella frontalis).

High-grade Astrocytoma (Glioblastoma Multiforme) in an Atlantic Spotted Dolphin (Stenella frontalis)

Journal of Comparative Pathology, 2015
This report describes the gross, microscopical and immunohistochemical features of a high-grade astrocytoma (glioblastoma multiforme) in an adult male Atlantic spotted dolphin (Stenella frontalis). On necropsy examination, a 5 × 2.5 × 2 cm, poorly demarcated, red, friable and locally expansile mass effaced the thalamus and the left periventricular ...

Examining shark bite scars on dolphins off Bimini, The Bahamas: Comparisons between bottlenose and Atlantic spotted dolphins

Marine Mammal Science, 2021
AbstractShark predation risk impacts many facets of dolphin life, including habitat use and foraging strategies. Because direct predation is rarely observed, researchers instead examine dolphins in situ for past injuries that can be attributed to sharks.

Understanding trophic transference role in mercury biomagnification and bioaccumulation in the Atlantic spotted dolphin (Stenella frontalis)

Chemosphere, 2023
Mercury is a metal of toxicological importance that occurs naturally. However, its concentration can be affected by anthropogenic activities and has the potential to bioaccumulate and biomagnify in food webs. Thus, knowing how its concentration varies along the trophic levels allows us to understand its potential risks to the biota.

Whistles emitted by Atlantic spotted dolphins (Stenella frontalis) in southeastern Brazil

The Journal of the Acoustical Society of America, 2010
The whistles of Atlantic spotted dolphins have been studied in a few localities of the North Atlantic Ocean and those studies revealed that the species emits whistles within a broad frequency range, with a high number of inflection points and presence of harmonics.

Contamination by chlorinated pesticides, PCBs and PBDEs in Atlantic spotted dolphin (Stenella frontalis) in western South Atlantic

Chemosphere, 2012
Chlorinated pesticides, PCBs and PBDEs were analysed in nine blubber samples of Atlantic spotted dolphins, Stenella frontalis, incidentally captured during fishing operations in southern and southeastern Brazil between 2005 and 2007. The majority of compounds analysed were detected, suggesting widespread contamination over the region.

Context specificity of Atlantic spotted dolphin acoustic signals in the Canary Islands

Ethology Ecology & Evolution, 2016
The behavioural context provides opportunities for studying the use and characteristics of acoustic signals. We analysed the context-specific use of acoustic signals in a population of Atlantic spotted dolphins around the Canary archipelago. We calculated the whistle diversity, the mean value of whistle stereotypy and the repetition rate of both tonal ...

Cerebral toxoplasmosis in Atlantic spotted dolphin stranded in Canary islands

2023
Toxoplasma gondii is a parasitic protozoan species belonging to the Family Sarcocystidae. The life cicle of T.gondii has two phases; a sexual phase, which take placein a definitive host (members of the family Felidae); and an asexual phase, in the intermediate hosts (any warm-blooded animal, including several species of marine mammals).
