PREGNANCY IS A DRAG FOR BOTTLENOSE DOLPHINS

Journal of Experimental Biology, 2011
![Figure][1] Lumbering around during the final weeks before delivery is tough for any pregnant mum. Most females adjust their movements to compensate for the extreme physical changes that accompany the later stages of pregnancy.

Bottlenose dolphin communities from the southern Brazilian coast: do they exchange genes or are they just neighbours?

, 2015
The genetic structure of bottlenose dolphin communities found along the southern Brazilian coast is reported in this study. Genetic structure analysis using biopsy samples from free ranging dolphins and tissue samples from stranded dolphins revealed a ...

Language Studies with Bottlenosed Dolphins

2004
Louis Herman conducts his dolphin research in tanks located at the Kewalo Basin Marine Mammal Laboratory in Honolulu, Hawaii. Visitors ascend stairs into a tower above two seawater tanks, one situated to the north and another to the south of the structure. The tanks are circular, 50 feet in diameter.

“The Bottlenose Dolphin” (An Eco-comic)

2020
Comics is a medium for transporting messages and information in a very direct and efficient way, since it is primarily based on visual information, which may be extremely reduced and focused. This makes it not only suitable especially for children, but also for adult people. Although comic magazines once have been considered as “junk”, comics today has

Echolocation system of the bottlenose dolphin

Acoustical Physics, 2004
The hypothesis put forward by Vel’min and Dubrovsky [1] is discussed. The hypothesis suggests that bottlenose dolphins possess two functionally separate auditory subsystems: one of them serves for analyzing extraneous sounds, as in nonecholocating terrestrial animals, and the other performs the analysis of echoes caused by the echolocation clicks of ...

Sounds Emitted by the Bottlenose Dolphin

Science, 1961
The sonic emissions of the bottlenose dolphin are remarkably complex. Three classes of these sounds are discussed and presented graphically. The sine-type wave whistles range in frequency from about 4000 to 18,000 cycles per second. The clicks contain components of this same frequency range plus some components of higher frequencies.

Modeling PCB-bioaccumulation in the Bottlenose Dolphin ( Tursiops truncatus ): estimating a dietary threshold concentration.

Environmental Science and Technology, 2013
An individually based (IB) model to predict PCB concentrations in the bottlenose dolphin population of Charleston, SC, USA, was developed with the aim to gain a better understanding of the bioaccumulation behavior and health risk of dietary PCBs across ...

Hematology of the bottlenose dolphin (Tursiops truncatus)

American Journal of Physiology-Legacy Content, 1964
The hematology of six bottlenose dolphins, kept in an aquarium filled with simulated sea water, has been studied. Blood samples were easily collected from a branch of the brachial vessels. With the exceptions of the low total red cell count, larger mean corpuscular volume, and the high normal eosinophil count, the other hematological parameters are ...

Directional properties of bottlenose dolphin (Tursiops truncatus) clicks, burst-pulse, and whistle sounds.

Journal of the Acoustical Society of America, 2012
The directional properties of bottlenose dolphin clicks, burst-pulse, and whistle signals were measured using a five element array, at horizontal angles of 0°, 45°, 90°, 135°, and 180° relative to a dolphin stationed on an underwater biteplate.

A DNA vaccine against dolphin morbillivirus is immunogenic in bottlenose dolphins

Veterinary Immunology and Immunopathology, 2007
The immunization of exotic species presents considerable challenges. Nevertheless, for facilities like zoos, animal parks, government facilities and non-profit conservation groups, the protection of valuable and endangered species from infectious disease is a growing concern.
