Negotiation, Sanctions, and Context Dependency in the Legume-Rhizobium Mutualism

Abstract: Two important questions about mutualisms are how the fitness costs and benefits to the mutualist partners are determined and how these mechanisms affect the evolutionary dynamics of the mutualism. We tackle these questions with a model of the legumerhizobium symbiosis that regards the mutualism outcome as a result of biochemical negotiations between the plant and its nodules. We explore the fitness consequences of this mechanism to the plant and rhizobia and obtain four main results. First, negotiations permit… Show more

“…Trader classes can belong to the same species as in mating or cooperative breeding markets (13,19) or to different species (mutualisms) (20,21). In mutualistic biological markets, both trader classes have an advantage over the other class in producing and providing their specialized commodity (22,23).…”

“…The term "negotiation" is used in the context of several studies of animal behavior, even for organisms for which the use of cognitive mechanisms can safely be excluded (Akçay and Roughgarden 2007;Akçay and Simms 2011), but the term obviously has different meanings for different authors. Most empirical studies concern negotiations over parental care within reproductive pairs or between parents and offspring: birds (Aves: Hinde and Kilner 2007;Kosztolanyi et al 2009;Lendvai et al 2009;Lessells and McNamara 2012;Meade et al 2011); beetles (Coleoptera: Smiseth et al 2006).…”

“…In the future, we should ask how far punishment or partner switching, in addition to the threat of early termination, may push the quality of service provided by cleaners towards higher levels of cooperation (for models addressing this issue, see [54][55][56]). More generally, given that there are so many possible mechanisms of partner control, we suggest that it is only by studying the impact of each mechanism on the level of cooperation versus exploitation that empirical studies can determine which forms of partner control are of real biological significance.…”
