Abstract

Those who practice organic or traditional agricuture have the sense that the biodiversity within their farms offers ecosystem services that contribute to the stability, productivity and sustainability of their systems. However, due to their complexity, ecological interactions are very dificult to tease out empirically,especially when these interactions are embedded in complex networks.The science of complexity offers a new platform to help us tease out those complex intercations and their consequences for agroecosystems. Recent studies that incorporate complex networks, non-linearities, stochasticity and, in particular, an added spacial dimension, reveal persistant ecological systems that generate ecosystem services as a result of ecological interactions. Here we describe our theoretical and empirical research of a complex interaction network that has an effect on at least four coffee pests, the coffee berry borer, the gree coffee scale, the coffee rust and the coffee leafminer.
