Age-specific foraging performance and reproduction in tool-using wild bottlenose dolphins
Effective foraging is necessary for nearly all animals, but most animals are not born with adult-like foraging performance. Instead, foraging skills are developed during an individual’s lifetime. Life-history theory predicts that adult-level foraging performance should be reached prior to the start of reproduction, but for most species, we know little about age-specific foraging in the wild. He...
متن کاملCalf Inspections of Fish Catches in Bottlenose Dolphins (tursiops Sp.): Opportunities for Oblique Social Learning?
In recent years, the study of social learning and culture in wild cetaceans has visibly increased (Rendell and Whitehead 2001, Mann and Sargeant 2003, Krützen et al. 2005). Some of the best evidence for some type of social learning in wild cetaceans comes from studies of vocal traditions in killer whales (Deecke et al. 2000, Yurk et al. 2002), song change in humpback whales (Noad et al. 2000), ...
متن کاملThe structure of a bottlenose dolphin society is coupled to a unique foraging cooperation with artisanal fishermen.
Diverse and localized foraging behaviours have been reported in isolated populations of many animal species around the world. In Laguna, southern Brazil, a subset of resident bottlenose dolphins (Tursiops truncatus) uses a foraging tactic involving cooperative interactions with local, beach-casting fishermen. We used individual photo-identification data to assess whether cooperative and non-coo...
متن کاملForaging Ecology and Maternal Transmission of Foraging Specializations of Bottlenose Dolphins (Tursiops truncatus) by
Bottlenose dolphins use a variety of foraging specializations to detect and pursue prey. Like other mammals, individual dolphins may use specialized foraging techniques that are shaped in response to habitat or particular prey resources. The long duration of the mother-calf bond presents an opportunity for mothers to transmit such specializations to their calves, and cases of observational lear...
متن کاملThe Ecological Conditions That Favor Tool Use and Innovation in Wild Bottlenose Dolphins (Tursiops sp.)
Dolphins are well known for their exquisite echolocation abilities, which enable them to detect and discriminate prey species and even locate buried prey. While these skills are widely used during foraging, some dolphins use tools to locate and extract prey. In the only known case of tool use in free-ranging cetaceans, a subset of bottlenose dolphins (Tursiops sp.) in Shark Bay, Western Austral...
