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...

Intra- and interspecific challenges modulate cortisol but not androgen levels in a year-round territorial damselfish

Ros, Albert F. H ; Vullioud, Philippe ; Bruintjes, Rick ; Vallat, Armelle ; Bshary, Redouan

In: The Journal of Experimental Biology, 2014, vol. 217, no. 10, p. 1768-1774

Interactions between individuals of different species are commonplace in animal communities. Some behaviors displayed during these interspecific social interactions may be very similar to those displayed during intraspecific social interactions. However, whether functional analogies between intra- and interspecific behaviors translate at the proximate level into an overlap in their underlying...

Wild vervet monkey infants acquire the food-processing variants of their mothers

Van de Waal, Erica ; Bshary, Redouan ; Whiten, Andrew

In: Animal Behaviour, 2014, vol. 90, p. 41-45

In the ability and motivation to copy others, social learning has been shown to provide a mechanism for the inheritance of behavioural traditions. Major questions remain about the circumstances and models that shape such social learning. Here, we demonstrate that behavioural food-processing variants among wild vervet monkey, Chlorocebus aethiops, mothers are matched by their infants in...

Negotiations over Grooming in Wild Vervet Monkeys (Chlorocebus pygerythrus)

Van de Waal, Erica ; Spinelli, Martina ; Bshary, Redouan ; Ros, Albert Frank Huascar ; Noë, Ronald

In: International Journal of Primatology, 2013, vol. 34, no. 6, p. 1153-1171

Mutual grooming plays a central role in the establishment and maintenance of social relationships in primates. Allogrooming has two main functions: hygiene and bonding with partners. The duration of grooming bouts is commonly used in studies of the functional aspects of grooming, but few reflect on the proximate mechanisms that determine grooming bout lengths. As it is highly unlikely that...

Referential gestures in fish collaborative hunting

Vail, Alexander L ; Manica, Andrea ; Bshary, Redouan

In: Nature Communications, 2013, vol. 4, p. 1765

In humans, referential gestures intentionally draw the attention of a partner to an object of mutual interest, and are considered a key element in language development. Outside humans, referential gestures have only been attributed to great apes and, most recently, ravens. This was interpreted as further evidence for the comparable cognitive abilities of primates and corvids. Here we describe a...
