Dolphins are among the most intelligent and endearing inhabitants of our oceans, captivating the hearts of people worldwide and connecting us to marine life. Unfortunately, many dolphin species face potential extinction due to human-induced threats such as habitat degradation, pollution, bycatch in fishing nets, climate change, and collisions with...

O litoral sul de Santa Catarina é uma área reprodutiva da baleia-franca-austral, que usa regularmente a região em intervalos trianuais. Entretanto, fatores como fenômenos climáticos podem afetar essa regularidade. A fim de testar se estas flutuações se mantêm, os dados coletados no monitoramento terrestre dos anos de 2020 e 2021 foram comparados co...

Após o fim da caça das baleias-francas, a interação com as atividades antrópicas, como a atividade pesqueira, é uma das principais ameaças à conservação desses animais no Sul do Brasil. De modo a identificar potenciais áreas de interação, foram realizadas entrevistas com pescadores artesanais ao longo da Área de Proteção Ambiental (APA da Baleia-Fr...

• The small population paradigm assumes that populations with low numbers of individuals intrinsically have a high probability of extinction. The small population of Lahille’s bottlenose dolphins Tursiops truncatus gephyreus that specializes in foraging with artisanal fishers in Laguna, southern Brazil, faces human pressures including bycatch in fi...

A subset of the bottlenose dolphin Tursiops truncatus gephyreus population in Laguna, southern Brazil, specialize in foraging cooperatively with fishermen. In this study, we describe reproductive parameters for these dolphins and investigate whether this specialized tactic generates reproductive advantages for females that frequently engage in this...

A small population of coastal bottlenose dolphins ( Tursiops truncatus gephyreus ) inhabits the inland waters of Laguna, southern Brazil. A subset of this population interacts with artisanal fishermen. This specialized foraging tactic structures dolphin society into ‘cooperatives' (participants of the interaction) and ‘non‐cooperatives' (non‐partic...

Individuals often associate socially with those who behave the sameway. This principle, homophily, could structure populations into distinct social groups. We tested this hypothesis in a bottlenose dolphin population that appeared to be clustered around a specialized foraging tactic involving cooperation with net-casting fishermen, but in which oth...

Adverse effects of exposure to persistent organic pollutants (POPs) threaten the maintenance of odontocete populations. In southern Brazil, coastal bottlenose dolphins from the Laguna Estuarine System (LES) and Patos Lagoon Estuary (PLE) were sampled using remote biopsies during the winter and summer months. Levels of bioaccumulated POPs were measu...

Recent years have seen an increasing interest in individual behavioral variation. However, the implications of such variation for population dynamics are often unknown. We studied the dynamics of a bottlenose dolphin (Tursiops truncatus gephyreus) population from southern Brazil, where some individuals forage cooperatively with artisanal fishermen....

Acoustic communication is a taxonomically widespread phenomenon, crucial for social animals. We evaluate social sounds from bottlenose dolphins (Tursiops truncatus) of Laguna, southern Brazil, whose social structure is organized around a cooperative for- aging tactic with artisanal fishermen. This tactic involves stereotyped and coordinated behavio...

Ship strikes are one of the major threats to large whales worldwide. The potential impact from increasing vessel traffic therefore is a concern for the future of the Brazilian humpback whale ( Megaptera novaeangliae ) population. In order to evaluate the risk of collision between large vessels and humpback whales along coastal shipping routes in th...
