Adjustments of levels of cooperation in cleaner wrasse "Labroides dimidiatus" : the effects of an audience and satiation

Pinto, Ana Isabel ; Bshary, Redouan (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2015.

Cooperation, the mutual helping between unrelated individuals, is an evolutionary puzzle. This is because helping is often an investment that must yield future benefits in order to be under positive selection. Generally, natural selection favours individuals that perform self-serving behaviour, and hence cheating is a major conceptual issue. However, examples of cooperation are abundant in...

Partner control mechanisms in repeated social interactions

Wubs, Matthias ; Bshary, Redouan (Dir.) ; Lehmann, Laurent (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Individuals that interact socially regularly have to make decisions whether to help another individual (provide some payoff benefit, possible at a personal payoff cost) or not. Here, a pair of individuals is best off if both individuals help each other, but a single individual may gain a relative payoff advantage by not helping (defecting) while the partner does choose to help, thus creating a...

Conflict management in free-ranging wolves, Canis lupus

Baan, Candice ; Bergmüller, Ralph ; Smith, Douglas W ; Molnar, Barbara

In: Animal Behaviour, 2014, vol. 90, p. 327-334

Individuals should invest in conflict management when the costs of conflicts outweigh their benefits. We investigated whether free-ranging wolves engage in conflict resolution. We predicted that reconciliation and consolation should occur because pack members are highly interdependent upon each other owing to the benefits that group members derive from cooperative breeding, cooperative hunting...

Strategic social behaviour in wild vervet monkeys

Borgeaud, Christèle ; Bshary, Redouan (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

In comparison to other vertebrates, primates have a large brain in relation to their body size. It has been hypothesised that the degree of social complexity is the major predictor for such variation. In group living species, individuals face various social challenges which can include finding the right balance between cooperation and competition with other group members. Thus to survive and...

The ecology underlying decision rules of bluestreak cleaner wrasse during client interactions

McAfoose, Sharon ; Bshary, Redouan (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Cooperation is defined as a ‘helping’ behaviour that provides direct fitness benefits to other individuals. Such behaviours have long intrigued biologists, as it poses a problem for classic evolutionary theory, i.e. why should an individual perform a behaviour that is beneficial to other individuals? Indeed, an expansive body of work on evolutionary game theory, as well as, empirical studies,...

La coopération européenne et les langues: retour aux fondements discursifs

Sokolovska, Zorana

In: Bulletin VALS-ASLA, 2017, vol. N° spécial, no. 1, p. 39-49

The aim of this paper is to examine the basis of the Council of Europe's discourse on "linguistic diversity" as resource for the achievement of the interstate cooperation. The study focuses on the discourse construction and legitimation processes in and by an institution with a specific political agenda of uniting European states and in a specific historical context. It draws on the analysis of...

Variation in Cleaner Wrasse Cooperation and Cognition: Influence of the Developmental Environment?

Wismer, Sharon ; Pinto, Ana I ; Vail, Alex L ; Grutter, Alexandra S ; Bshary, Redouan

In: Ethology, 2014, vol. 120, no. 6, p. 519-531

Deviations from model-based predictions of strategies leading to stable cooperation between unrelated individuals have raised considerable debate in regards to decision- making processes in humans. Here, we present data on cleaner wrasse (Labroides dimidiatus) that emphasize the importance of generalizing this discussion to other species, with the aim to develop a coherent theoretical...
