However, clear differences in water temperature, habitat features and fish abundance between SA and Tasmania may contribute to the contemporary isolation observed between dolphin populations. Our findings have important consequences for developing conservation management strategies, because SA has the largest ...
at various scales. In cetaceans, intraspecific variation in acoustic repertoires has been linked to ecological factors, geographical barriers, and social processes. For the common bottlenose dolphin (Tursiops truncatus), studies on acoustic variability are scarce, focus on a...

Diet changes due to the stock depletion of the main prey have already been suggested for common dolphin in Portugal (i.e. sardine, Marçalo et al., 2018) and minke whales in the Barents Sea (i.e. capelin and herring, Haug et al., 2002). In addition to the reported geographical ...
Conservation status: “Least Concern.” The bottlenose dolphin has a conservation status of “Least Concern” on the Red List of the International Union for Conservation of Nature notwithstanding the following continuous threats: –Bycatch in gillnets, trawls and draft nets. ...
An adult common bottlenose dolphin (Tursiops truncatus) was found dead and in advanced autolysis in Paraíba state, northeastern Brazil, on July 19th, 2020. Upon gross examination, 80% of the body surface presented disseminated rhomboid cutaneous lesions ranging from 4 to 6 cm-width, characterized...
The Amazon River Dolphin, also known as the boto or pink river dolphin, lives exclusively in freshwater. Their estimated population throughout the Amazon River basins is tens of thousands. These dolphins are born gray but gradually turn pink as they age. They are recognizable by their unique sm...
The dose-response data of AgNPs on the leukocytes of cetaceans are invaluable for evaluating the adverse health effects in cetaceans and for proposing a conservation plan for marine mammals. Silver nanoparticles (AgNPs) have been extensively used in numerous commercial products including textiles, ...
Fig. 1. Hepatic concentrations and minimum dolphin age (years) (A) and principal component analysis (PCA) (B) of trace elements detected in mass-stranded common dolphin (Delphinus delphis) in Okukari Bay, Marlborough Sounds (27 February 2019) and Taupō Bay, Northland (13 April 2019), New...
However, the lack of conservation of the ELP/CTI C-terminus suggested these areas may have species-specific effects. Interestingly, the conservation of the TGA codon used by the tammar, koala, pig, dolphin and cow for all species but the cat (CGA) suggested it was the ancestral ELP/CTI ...
