“…These arguments are in line with basic optimal foraging theory predictions that satiated individuals should be risk averse. The empirical results by Triki and colleagues [21] suggest that the opposing forces are overall in balance. Data sets were not big enough to determine whether client species differ in the way they adjust evasive action probabilities to changes in market conditions.…”

“…Most models of biological market theory explored evolutionary time scales [10,[16][17][18][19]; for partial exceptions see [20,21]. Some species may be adapted to market conditions that are relatively stable over evolutionary time, while others are assumed to be adapted to react optimally to fluctuations in the market values of individuals and/or good and services [12].…”

“…21,[38][39][40][41][42] that have not been used in reviews but affect our thinking on BMT. In one paper, a reduction in cleaner densities did not lead to predicted changes in service quality [21]. Another paper documented in detail how partner choice options must be combined with other variables such parasite load, mucus quality and manoeuvrability to predict realised service quality [43].…”

“…Data sets were not big enough to determine whether client species differ in the way they adjust evasive action probabilities to changes in market conditions. If they did, the prediction would be that cleaners may selectively increase or decrease service quality according to client species when the market shifts in their favour [21].…”

“…prioritise clients according to own preferences rather than according to client choice options [38]. Combining data with a learning model [21,40,55] revealed that temporal discounting mechanism allows for such a decision-rule when market conditions favour cleaners, and also to prioritise visitors if market conditions are more balanced [38].…”

Most mutually beneficial social interactions (cooperation within species, mutualism between species) involve some degree of partner choice. In an analogy to economic theory as applied to human trading practices, biological market theory (BMT) focusses on how partner choice affects payoff distributions among non-human traders. BMT has inspired a great diversity of research, including research on the mutualism between cleaner fish Labroides dimidiatus and other marine fish, their ‘clients’. In this mutualism, clients have ectoparasites removed and cleaners obtain food in return. We use the available data on L. dimidiatus cleaner–client interactions to identify avenues for future expansion of BMT. We focus on three main topics, namely how partner quality interacts with supply-to-demand ratios to affect service quality, the role of threats and forms of forceful intervention, and the potential role of cognition. We consider it essential to identify the specifics of each biological market as a basis for the development of more sophisticated BMT models.

Game theory in biology: 50 years and onwards

Game theory in biology gained prominence 50 years ago, when Maynard Smith & Price formulated the concept of an evolutionarily stable strategy (ESS). Their aim was to explain why conflicts between animals of the same species usually are of a ‘limited war’ type, not causing serious injury. They emphasized that game theory is an alternative to previous ideas about group selection, which were used by ethologists to explain limited aggression. Subsequently, the ESS concept was applied to many phenomena with frequency dependence in the evolutionary success of strategies, including sex allocation, alternative mating types, contest behaviour and signalling, cooperation, and parental care. Both the analyses of signalling and cooperation were inspired by similar problems in economics and attracted much attention in biology. Here we give a perspective on which of the ambitions in the field have been achieved, with a focus on contest behaviour and cooperation. We evaluate whether the game-theoretical study of the evolution of cooperation has measured up to expectations in explaining the behaviour of non-human animals. We also point to potentially fruitful directions for the field, and emphasize the importance of incorporating realistic behavioural mechanisms into models. This article is part of the theme issue ‘Half a century of evolutionary games: a synthesis of theory, application and future directions’.
