Hormonal mechanisms of cooperative behaviour
TLDR
The aim here is to focus on the potential role of neuroendocrine mechanisms on the regulation of the expression of cooperative behaviour in vertebrates and to evaluate how hormones may influence known cognitive modules that are involved in decision-making processes that may lead to cooperative behaviour.
Inclusive fitness theory and eusociality
TLDR
It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.
Red colobus and Diana monkeys provide mutual protection against predators
TLDR
Since neither monkey species improves its foraging success when associated, this study shows that predation can both maintain and be the ultimate cause of interspecific associations.
The Predator Deterrence Function of Primate Alarm Calls
TLDR
It is concluded that the high alarm call rates to leopards are part of an anti-predator strategy in primates that may have evolved to deter predators that depend on surprise.
Biting cleaner fish use altruism to deceive image–scoring client reef fish

TLDR
It appears that cleaners indeed have an image score, which selects for cooperative cleaners, however, it is suggested that image–scoring individuals may be exploitable by cheaters if pay–offs vary between interactions.
The cleaner wrasse, Labroides dimidiatus, is a key organism for reef fish diversity at Ras Mohammed National Park, Egypt
TLDR
It is demonstrated that cleaner fish are a key organism for local reef fish diversity, and effects were most pronounced for client species that visit reef patches and soon move off again, and less pronounced for resident clients that do not move between reef patches.
Image scoring and cooperation in a cleaner fish mutualism
TLDR
It is found that eavesdropping clients spent more time next to ‘cooperative’ than ‘unknown cooperative level’ cleaners, which shows that clients engage in image-scoring behaviour, which provides experimental evidence for both of the requirements in a cleaning mutualism involving the cleaner fish Labroides dimidiatus.
Asymmetric cheating opportunities and partner control in a cleaner fish mutualism
TLDR
The chasing of cleaners appeared to be a form of punishment, imposing costs on the cleaner at the client's (momentary) expense, as jolts were on average less frequent during interactions between cleaners and individuals that had terminated their previous interaction by aggressive chasing.
