Numerous species of cetaceans have been recorded in mixed-species groups (MSGs). By
forming groups with individuals of different species, cetaceans may reduce predation risk …

The genus Balaenoptera comprises seven species and 15 subspecies whose conservation
statuses range from “Endangered” to “Least Concern” and “Data Deficient”. In addition to …

We describe the temporal and spatial patterns of three tetrapod groups (sea turtles,
seabirds, and cetaceans) stranded in southeast Brazil, based on daily beach surveys of …

Coastal and offshore ecotypes of common bottlenose dolphins have been recognized in the
western South Atlantic, and it is possible that trophic niche divergence associated with social …

The ingestion of debris by marine fauna is a growing threat to biodiversity. This study aimed
to evaluate and characterize litter ingestion by odontocetes from the Western South Atlantic …

We investigated the trophic structure and habitat use of ten cetacean species occurring in
the oceanic waters of the western South Atlantic using naturally-occurring stable isotopes …

Characterizing the patterns of stable carbon (δ 13 C) and nitrogen (δ 15 N) isotopes at the
base of the food webs (baseline) is essential in ecological studies for assessing the feeding …

Due to their worldwide distribution and occupancy of different types of environments,
bottlenose dolphins display considerable morphological variation. Despite limited …

Large diversity and abundance of cetacean species occur along the Brazilian outer
continental shelf and slope waters. In the present study, we analyzed carbon (δ 13 C) and …

Kogia sima and Kogia breviceps are apex predators of mesopelagic trophic webs being far
from most anthropogenic threats. However, chemical pollutants and naturally synthesized …
