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 and… Expand

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. These… Expand

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 horizontally… Expand

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 to… Expand

Experimental demonstration of species coexistence enabled by dispersal limitation
Summary 1 Dispersal limitation is widely invoked to explain species coexistence and cooperation in the face of competition and cheating. However, empirical evidence from natural ecosystems for… Expand

The reproductive phenology of an Amazonian ant species reflects the seasonal availability of its nest sites
In saturated tropical ant assemblages, reproductive success depends on queens locating and competing for scarce nest sites. Little is known about how this process shapes the life histories of… Expand

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 sometimes… Expand

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 neotropical… Expand

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 on… Expand
