Herpesviral infection in a Guiana dolphin ( Sotalia guianensis ) from the northern coast of Brazil
We describe herein herpesvirus-associated genital lesions in a Guiana dolphin ( Sotalia guianensis) from the northern Brazilian coast. Papillary lesions on the vulva, with epithelial hyperplasia, swollen keratinocytes, and intranuclear inclusions, were positive for a herpesvirus ( Gammaherpesvirinae subfamily).

Guiana dolphin strandings are spatially concentrated and increasing in Brazil
Guiana dolphins (Sotalia guianensis) serve as critical environmental sentinels, yet they face escalating threats from human activities in coastal and estuarine ecosystems. Despite extensive data collection, integrated assessments of large-scale stranding

This chapter explores the two species of the genus Sotalia, riverine Sotalia fluviatilis and marine S. guianensis. The two Sotalia species are very similar in coloration, differing mainly in body size and number of teeth, and somewhat resembling a small ...

Feeding habits of the Guiana dolphin, Sotalia guianensis (Cetacea: Delphinidae), in Norte Bay, southern Brazil [PDF]
The stomach contents of 18 Guiana dolphins stranded or accidentally caught by fishing around Norte Bay of Santa Catarina Island between 1990 and 2006 were examined. The small population of Guiana dolphins studied showed a varied diet, and prey was caught

Studying the abundance, distribution, and habitat use of dolphins can provide essential information for preserving marine biodiversity, managing coastal ecosystems, and enhancing our understanding of aquatic life. Herein, we investigated the abundance, distribution, and habitat use of two dolphin populations—Guiana dolphins (Sotalia guianensis) and ...

Portable Molecular Diagnostics for Cetacean Morbillivirus: Development of a Reverse Transcription Insulated Isothermal PCR (RT-iiPCR) for Global Surveillance. [PDF]
Cetacean morbillivirus (CeMV) drives recurrent unusual‐mortality events, yet surveillance is uneven where laboratory capacity is limited. We developed a portable reverse transcription‐insulated isothermal PCR (RT‐iiPCR) assay targeting a conserved phosphoprotein (P)‐gene segment and evaluated analytical performance, tissue‐level clinical sensitivity ...

Response of Guiana dolphins to the construction of a bridge in Ilhéus, Northeastern Brazil. [PDF]
This study aimed to investigate whether the use of space and movements of Guiana dolphins were altered during the construction of a cable-stayed bridge at the mouth of the Cachoeira River estuary in Ilhéus, Brazil. We described and compared the visitation rate, use of space, and movements of the Guiana dolphins across two periods: before the ...

Eye morphology of Guiana dolphins (Sotalia guianensis) and Clymene dolphins (Stenella clymene)
Recent studies showed that vision and hearing in dolphins are mechanisms for perception of the environment, and transmission of information among individuals. Considering that Guiana dolphins (Sotalia guianensis) are distributed in costal regions, and Clymene dolphins (Stenella clymene) are found in oceanic environments, the objective of this study was

In many regions of the world, the use of cetaceans as bait or protein source has been reported. In most cases the individuals are from bycatch but also from intentionally killed animals.
