Economic game theory for mutualism and cooperation.
We review recent work at the interface of economic game theory and evolutionary biology that provides new insights into the evolution of partner choice, host sanctions, partner fidelity feedback andExpand
Stability and phylogenetic correlation in gut microbiota: lessons from ants and apes
Correlation between gut microbiota and host phylogeny could reflect codiversification over shared evolutionary history or a selective environment that is more similar in related hosts. TheseExpand
Conflict over Reproduction in an Ant‐Plant Symbiosis: Why Allomerus octoarticulatus Ants Sterilize Cordia nodosa Trees
The evolutionary stability of mutualism is thought to depend on how well the fitness interests of partners are aligned. Because most ant‐myrmecophyte mutualisms are persistent and horizontallyExpand
Economic contract theory tests models of mutualism
Although mutualisms are common in all ecological communities and have played key roles in the diversification of life, our current understanding of the evolution of cooperation applies mostly toExpand
Current issues in the evolutionary ecology of ant-plant symbioses.
Ant-plant symbioses involve plants that provide hollow structures specialized for housing ants and often food to ants. In return, the inhabiting ants protect plants against herbivores and sometimesExpand
Ant species confer different partner benefits on two neotropical myrmecophytes
The dynamics of mutualistic interactions involving more than a single pair of species depend on the relative costs and benefits of interaction among alternative partners. The neotropicalExpand
Ants and Ant Scent Reduce Bumblebee Pollination of Artificial Flowers
Ants on flowers can disrupt pollination by consuming rewards or harassing pollinators, but it is difficult to disentangle the effects of these exploitative and interference forms of competition onExpand
Why ant pollination is rare: new evidence and implications of the antibiotic hypothesis
The antibiotic hypothesis proposes that ant pollination is rare at least in part because the cuticular antimicrobial secretions of ants are toxic to pollen grains. We tested this hypothesis byExpand
Seed handling behaviours of native and invasive seed‐dispersing ants differentially influence seedling emergence in an introduced plant
Myrmecochory, or ant‐mediated seed dispersal, is an important ecological interaction in which ants benefit by gaining nutrition from lipid‐rich elaiosomes attached to seeds and plants benefit fromExpand
