Reproductive morphology of female Guiana dolphins (Sotalia guianensis) [PDF]

Anais da Academia Brasileira de Ciências, 2015
The reproductive morphology of cetaceans is poorly studied and, despite the large number of strandings, reports on this subject are scarce due to access to carcasses mostly in an advanced state of decomposition. The present study aimed to describe histological characteristics of the female genital tract ofSotalia guianensis, in order to assist in ...

Feeding Strategies of the Guiana Dolphin Sotalia guianensis [PDF]

The Open Marine Biology Journal, 2009
The aim of this study was to characterize the feeding behavior of the Guiana dolphin, S. guianensis, through description and quantification of the strategies used by the dolphins, and possibly to apply this patterns to other areas in its distribution. Data were collected during systematic boat surveys, between November/1996 and May/1997, with 120 hours

Tidal and seasonal influences in dolphin habitat use in a southern Brazilian estuary

Scientia Marina, 2017
In this study we describe how franciscana and Guiana dolphin habitat use is influenced by tidal cycles and seasonality in Babitonga Bay. The franciscanas use a greater area in winter and a smaller area in summer, but the extent of the area used did not ...

Health conditions of Guiana dolphins facing cumulative anthropogenic impacts

Mammalian Biology, 2022
AbstractCoastal areas are associated with anthropogenic activities and stressors that can expose the marine fauna to negative cumulative impacts. Apex predators, such as dolphins, can flag the quality of their environment through health parameters such as cutaneous and body conditions.
