Dolphin interactions with the mullet artisanal fishing on Southern Brazil: a qualitative and quantitative approach

TLDR
A detailed analysis of the interactions between Tursiops truncatus and the artisanal fishing of mullets is presented at two localities in the south of Brazil: Laguna and Inibe/Tramandai.
Abstract
A detailed analysis of the interactions between Tursiops truncatus (Montagu, 1821) and the artisanal fishing of mullets (Mugil spp.) is presented at two localities in the south of Brazil: Laguna (Santa Catarina) and Inibe/Tramandai (Rio Grande do Sul). Its behavioral strategies and the advantages of their association are re-described and quantified based on the success of the capture and on the selectivity of the prey sizes. The mullets are the main resource involved (92% to 75%) both at numerical level and as biomass. Twenty individuals of Tursiops truncatus participated in the interactions in Laguna and 9 in Imbe/Tramandai. The participation and learning of calves is also reported.

Culture in whales and dolphins

TL;DR: The complex and stable vocal and behavioural cultures of sympatric groups of killer whales (Orcinus orca) appear to have no parallel outside humans, and represent an independent evolution of cultural faculties.

Culture and conservation of non-humans with reference to whales and dolphins: review and new directions

TL;DR: It is suggested that non-human culture should be integrated into conservation biology when considering populations with such attributes, and also more generally by refining definitions of evolutionarily significant units and considering how cultural attributes may change the authors' perspectives of non-humans.

Specialization and development of beach hunting, a rare foraging behavior, by wild bottlenose dolphins (Tursiops sp.)

TL;DR: Beach hunting likely involves vertical social learning by calves, while individual, horizontal, and (or) oblique learning may occur among individuals who frequent coastal habitats.

Culture in Whales and Dolphins

Hal Whitehead
TL;DR: It is shown that much of the behavioral repertoire of many cetaceans is learned socially and constitutes culture, and culture may also be an important attribute of other marine mammals, with the foraging techniques of sea otters.

On Optimal Use of a Patchy Environment

TL;DR: A graphical method is discussed which allows a specification of the optimal diet of a predator in terms of the net amount of energy gained from a capture of prey as compared to the energy expended in searching for the prey.

Theory of Feeding Strategies

TL;DR: Throughout, emphasis will be placed on strategic aspects of feeding rather than on what Holling (75) has called "tactics," and possible answers to the first problem may be given to the second problem.

The Ecology of Mutualism

TL;DR: In this paper, the authors define mutualism as "an interaction between species that is beneficial to both" since it has both historical priority (311) and general currency (general currency).
