Morbillivirus Infections in Aquatic Mammals: A Brief Overview
Journal of Veterinary Medicine Series A, 2005SummarySince 1987, at least eight morbillivirus infection (MI) epidemics have caused mass mortality of several free‐living pinniped and cetacean populations around the world. The responsible agents, all belonging to the genus Morbillivirus (family Paramyxoviridae), have been characterized as either ‘canine distemper virus’ strains, infecting pinnipeds,

Lower size limit of aquatic mammals
American Journal of Physics, 1999Warm blooded aquatic mammals require a minimum diameter of about 15 cm in order to survive in cold oceans. This follows from the thermal balance and the diameter-to-length aspect ratio D/L≈1/4 of minimum drag, which is characteristic for fast swimming animals.

1989
Cold water has been described as the harshest thermal environment encountered by mammals anywhere on earth (Irving 1973). This is a perception undoubtedly reinforced by our own limited thermoregulatory competence in the aquatic medium. In 0°C water, the rectal body temperature (Tb) of an adult human may drop at a rate of 0.07–0.08°C min-1, resulting in

Evoked Potential Audiometry in Aquatic Mammals
2012Investigation of the influence of noise on the hearing of aquatic mammals requires appropriate methods of audiometry to assess any temporal or permanent hearing sensitivity shift. The auditory evoked potential (AEP) method is widely used for this purpose. It does not require long training of the subject, is not time consuming, and therefore may be used

Somatic Sense in Aquatic Mammals
2001Somatic sense in cetaceans did not attract as much attention of investigators as the auditory and visual ones. So available data in this field are restricted. Morphological studies have shown the presence of both incapsulated and free nerve endings in the dolphin’s skin, especially numerous at the head and snout, around the blowhole, and around the ...

Method for communicating with aquatic mammals
The Journal of the Acoustical Society of America, 1982A phonetic alphabet for communicating with dolphins, porpoises and whales includes three basic geometric shapes, various combinations of which are used to represent speech sounds. The alphabet consists of eighteen symbols which may be understood by animals trained to identify these symbols with words by using their innate echolocation sensory ...
