Underwater Noise in an Impacted Environment Can Affect Guiana Dolphin Communication

Marine Pollution Bulletin, 2017
This study focused on whistles produced by Guiana dolphin under different noise conditions in Guanabara Bay, southeastern Brazil. Recording sessions were performed with a fully calibrated recording system. Whistles and underwater noise levels registered during two behavioral states were compared separately between two areas.

Habitat use of Guiana dolphin Sotalia guianensis in a heavily urbanized embayment

Marine Ecology Progress Series, 2023
Understanding environmental and anthropogenic variables that influence the presence of dolphins in coastal areas is fundamental for conservation planning and forecasting. In this study, we applied generalized additive models to identify areas of high probability of occurrence of Guiana dolphins in Mucuripe embayment, a heavily urbanized area in ...

Population parameters of Guiana dolphins (Sotalia guianensis) in a southern Brazilian estuary

Mammalian Biology, 2023
Populations of many coastal cetaceans are threatened by negative anthropogenic impacts. Key precursors to effective recovery plans include understanding life histories and population parameters to establish baselines for subsequent changes. Here, we provide this information for one of the largest populations of Guiana dolphins (Sotalia guianensis), in ...

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 ...

Ecologically driven differences in individual diet specialization across three populations of Guiana dolphin

Oecologia, 2023
Populations usually considered foraging generalists may include specialized individuals that feed on a restricted subset of the prey spectrum consumed by the population. By analyzing the time series of δ13C and δ15N values in sequential growth layer groups within tooth dentin, we measured population- and individual-level variation in resource use of ...

Guiana Dolphin (Sotalia guianensis) in the Southern Gulf of Venezuela: Seasonal Distribution, Group Size, and Habitat Use

Regional Studies in Marine Science, 2019
Small cetaceans, such as the Guiana dolphin (Sotalia guianensis), do not migrate long distances to forage but use rather small areas subject to food source variations.
