Partner control mechanisms in repeated social interactions

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

Thèse de doctorat : Université de Neuchâtel, 2017.

Les individus qui interagissent socialement doivent souvent décider entre aider leur prochain, en leur procurant un bénéfice a un possible cout, ou pas. Tandis qu'une paire d'individus s'en sort mieux si les deux s'entraident, un individu peut tirer un bénéfice relatif s'il se décide à ne pas aider tandis que l'autre l'aide. Cette situation crée un dilemme social. Parce que les...

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.

La coopération est définie comme un «comportement d'aide» qui offre des avantages directs à d'autres individus. Un tel comportement a longtemps intrigué les biologistes car il pose un problème pour la théorie évolutive classique : pourquoi un individu devrait-il effectuer un comportement qui bénéficie un autre individu plutôt que lui-même? En effet, un vaste ensemble de travaux sur...

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...

Indo-Pacific parrotfish exert partner choice in interactions with cleanerfish but Caribbean parrotfish do not

Soares, Marta C ; Cardoso, Sónia C ; Nicolet, Katia J ; Côté, Isabelle M ; Bshary, Redouan

In: Animal Behaviour, 2013, vol. 86, no. 3, p. 611-615

Cooperation theory puts a strong emphasis on partner control mechanisms that have evolved to stabilize cooperation against the temptation of cheating. The marine cleaning mutualism between the Indo-Pacific bluestreack cleaner wrasse, Labroides dimidiatus, and its reef fish ‘clients’ has been a model system to study partner control mechanisms and counterstrategies. These cleaners...
