Sensitivity of a tucuxi (Sotalia fluviatilis guianensis) to airborne sound

The Journal of the Acoustical Society of America, 2005
Auditory 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.

Burst pulses of Guiana dolphin (Sotalia guianensis) in southeastern Brazil

The Journal of the Acoustical Society of America, 2017
Acoustic 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 ...

Evidence for signature whistles in Guiana dolphins (Sotalia guianensis) in Ilhéus, northeastern Brazil

The Journal of the Acoustical Society of America, 2014
Signature whistles have been widely studied in bottlenose dolphins (Tursiops truncatus). A recent study suggested the occurrence of signature whistles in Guiana dolphins (Sotalia guianensis) but could not identify the whistlers. The objective of this study is to describe the whistle characteristics in the population of S.

Characterisation and classification method of burst pulses produced by Guiana dolphins (Sotalia guianensis)

Bioacoustics, 2021
Although burst pulses are the least studied sounds produced by odontocetes, their characterisation is essential to describe the acoustic repertoire of a species.

Twelve microsatellite loci for marine and riverine tucuxi dolphins (Sotalia guianensis and Sotalia fluviatilis)

Molecular Ecology Notes, 2007
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 ...
