Risk, Networks, and Ecological Explanations for the Emergence of Cooperation in Commons Governance
The commons literature increasingly recognizes the importance of contextual factors in driving collaboration in governance systems. Of particular interest are the ways in which the attributes of a resource system influence the dynamics of cooperation. While this may occur through many pathways, we investigate the mechanisms by which ecological factors influence both the risk of cooperation as w...
متن کاملEvolving ecological networks and the emergence of biodiversity patterns across temperature gradients.
In ectothermic organisms, it is hypothesized that metabolic rates mediate influences of temperature on the ecological and evolutionary processes governing biodiversity. However, it is unclear how and to what extent the influence of temperature on metabolism scales up to shape large-scale diversity patterns. In order to clarify the roles of temperature and metabolism, new theory is needed. Here,...
متن کاملEmergence of Communication Networks
C ommunication networks are the patterns of contact between communication partners that are created by transmitting and exchanging messages through time and space. These networks take many forms in contemporary organizations, including personal contact networks, flows of information within and between groups, strategic alliances between firms, and global network organizations , to name but a fe...
متن کاملShape of ecological networks.
We study the statistics of ecosystems with a variable number of coevolving species. The species interact in two ways: by prey-predator relationships and by direct competition with similar kinds. The interaction coefficients change slowly through successful adaptations and speciations. They are treated as quenched random variables. These interactions determine long-term topological features of t...
متن کاملEmergence of robustness in networks of networks.
A model of interdependent networks of networks (NONs) was introduced recently [Proc. Natl. Acad. Sci. (USA) 114, 3849 (2017)PNASA60027-842410.1073/pnas.1620808114] in the context of brain activation to identify the neural collective influencers in the brain NON. Here we investigate the emergence of robustness in such a model, and we develop an approach to derive an exact expression for the rand...
