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...

The cleaning goby mutualism: a system without punishment, partner switching or tactile stimulation

In the cleanerfish–client mutualism involving the Indo-Pacific cleaner wrasse Labroides dimidiatus and its reef fish clients, mechanisms such as ‘tactile stimulation’, partner switching and punishment are used by clients to control cheating by cleaners. We sought to establish whether these behaviours are general features of cleaning mutualisms by examining their presence in...

Punishment and partner switching cause cooperative behaviour in a cleaning mutualism

Bshary, Redouan ; Grutter, Alexandra S.

In: Biology Letters, 2005, vol. 1, no. 4, p. 396-399

What are the mechanisms that prevent partners from cheating in potentially cooperative interactions between unrelated individuals? The cleaner fish Labroides dimidiatus and client reef fish both benefit from an interaction as long as the cleaner eats ectoparasites. However, the cleaner fish prefers some client mucus, which constitutes cheating. Field observations suggested that clients...

Experimental evidence that partner choice is a driving force in the payoff distribution among cooperators or mutualists : the cleaner fish case

Bshary, Redouan ; Grutter, Alexandra S.

In: Ecology Letters, 2002, vol. 5, p. 130-136

Supply and demand largely determine the price of goods on human markets. It has been proposed that in animals, similar forces influence the payoff distribution between trading partners in sexual selection, intraspecific cooperation and interspecific mutualism. Here we present the first experimental evidence supporting biological market theory in a study on cleaner fish, Labroides dimidiatus....
