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...

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...

Social games between bonobos and humans: evidence for shared intentionality?

Pika, Simone ; Zuberbühler, Klaus

In: American Journal of Primatology, 2008, vol. 70, no. 3, p. 207-210

"Triadic social games are interesting from a cognitive perspective because they require a high degree of mutual social awareness. They consist of two agents incorporating an object in turn-taking sequences and require individuals to coordinate their attention to the task, the object, and to one another. Social games are observed commonly in domesticated dogs interacting with humans, but they have...

Vocal, gestural and locomotor responses of wild chimpanzees to familiar and unfamiliar intruders : a playback study

Herbinger, Ilka ; Papworth, Sarah ; Boesch, Christophe ; Zuberbühler, Klaus

In: Animal behaviour, 2009, vol. 78, no. 6, p. 1389-1396

Wild chimpanzees can be dangerously violent against individuals that do not belong to their community, indicating a strong selection pressure on decision-making abilities in this context. The presence of a neighbouring male indicates a serious threat, although encountering an unfamiliar male is potentially even more dangerous because it indicates the arrival of a new group with whom the subjects...

Distinguishing four fundamental approaches to the evolution of helping

Bshary, Redouan ; Bergmüller, Ralph

In: Journal of Evolutionary Biology, 2008, vol. 21, no. 2, p. 405–420

The evolution and stability of helping behaviour has attracted great research efforts across disciplines. However, the field is also characterized by a great confusion over terminology and a number of disagreements, often between disciplines but also along taxonomic boundaries. In an attempt to clarify several issues, we identify four distinct research fields concerning the evolution of helping:...
