Integrating cooperative breeding into theoretical concepts of cooperation
In cooperative breeding systems, some individuals help to raise offspring that are not their own. While early explanations for such altruistic behaviour were predominantly based on kin selection,Expand

Hormonal mechanisms of cooperative behaviour
Research on the diversity, evolution and stability of cooperative behaviour has generated a considerable body of work. As concepts simplify the real world, theoretical solutions are typically alsoExpand

Red colobus and Diana monkeys provide mutual protection against predators
We tested the hypothesis that red colobus monkeys, Procolobus badius and Diana monkeys, Cercopithecus diana in Taï National Park, Ivory Coast, associate to increase safety from predation. We recordedExpand

The Predator Deterrence Function of Primate Alarm Calls
It is generally assumed that alarm calls function in intraspecific communication, for example to warn close relatives about the presence of a predator. However, an alternative hypothesis suggestsExpand

The cleaner wrasse, Labroides dimidiatus, is a key organism for reef fish diversity at Ras Mohammed National Park, Egypt
Summary 1 In marine cleaning symbioses, small fish or shrimps remove ectoparasites and other material from cooperating ‘client’ fish. Until now, there has been conflicting evidence with respectExpand

Asymmetric cheating opportunities and partner control in a cleaner fish mutualism
How can cooperation persist if, for one partner, cheating is more profitable than cooperation in each round, while the other partner has no option to cheat? Our laboratory experiments suggest thatExpand

Adult Cleaner Wrasse Outperform Capuchin Monkeys, Chimpanzees and Orang-utans in a Complex Foraging Task Derived from Cleaner – Client Reef Fish Cooperation
The insight that animals' cognitive abilities are linked to their evolutionary history, and hence their ecology, provides the framework for the comparative approach. Despite primates renowned dietaryExpand
