Evolution of mutualism through spatial effect

WebAbstract. Historically, studies of the population ecology of mutualism have been largely divorced from the key principles (e.g., density dependence, functional responses, consumer–resource theory) that have shaped our understanding of the dynamics of predation and competition.
