High initial and minimum frequencies of Sotalia guianensis whistles in the southeast and south of Brazil

The Journal of the Acoustical Society of America, 2013
Recent studies have proposed latitudinal variations for the whistles of Sotalia guianensis, since parameters of frequency increase from the southernmost distribution of the species (State of Santa Catarina, Brazil) toward the North. The last study on the whistles of S.

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 ...

Collateral fishing mortality of Guiana dolphins (Sotalia guianensis) at a World Heritage Site

Collateral fishing mortality is a major threat to small cetaceans worldwide, yet comprehensive spatio-temporal assessments remain limited, particularly in biodiversity hotspots. We analysed eight years (2016–2023) of stranding data for Guiana dolphins (Sotalia guianensis) along the Paraná coast, southern Brazil, including a UNESCO World Heritage Site ...
