Sensitivity of a tucuxi (Sotalia fluviatilis guianensis) to airborne sound
The Journal of the Acoustical Society of America, 2005Auditory systems of cetaceans are considered highly specialized for underwater sound processing, whereas the extent of their hearing capacity in air is still a point of issue. In this study, the sensitivity to airborne sound in a male tucuxi (Sotalia fluviatilis guianensis) was tested by means of a go/no go response paradigm.

AbstractTwelve dinucleotide polymorphic microsatellite loci were isolated from the marine tucuxi dolphin (Sotalia guianensis). Levels of genetic diversity were assessed using 34 individuals from the coasts of Rio de Janeiro and Pará, Brazil. Numbers of alleles varied between two and 14, and observed and expected heterozygosities ranged from 0.040 to 0 ...

Burst pulses of Guiana dolphin (Sotalia guianensis) in southeastern Brazil
The Journal of the Acoustical Society of America, 2017Acoustic studies of Guiana dolphin have been focused on whistles, with little known about pulse signals in this species. This study characterized the temporal and spectral properties of Guiana dolphin burst pulses. Groups of 2 to 23 Guiana dolphins were recorded while feeding and socializing in shallow waters in Guanabara Bay, southeastern Brazil, in ...

Whistles of boto, Inia geoffrensis, and tucuxi, Sotalia fluviatilis
The Journal of the Acoustical Society of America, 2001Whistles were recorded and analyzed from free-ranging single or mixed species groups of boto and tucuxi in the Peruvian Amazon, with sonograms presented. Analysis revealed whistles recorded falling into two discrete groups: a low-frequency group with maximum frequency below 5 kHz, and a high-frequency group with maximum frequencies above 8 kHz and ...
