DESCRIPTION:In ecology\, interactions are important. That is why ecologist
 s use network models to study communities and ecosystems. It is only a sma
 ll step to recognise that some interactions will be more important than ot
 hers. Yet\, until recently\, in ecological theory the strength of interact
 ions has been largely neglected. In this talk I will show how observations
  of the energy flow in ecosystems reveal characteristic patterns in intera
 ction strength underlying system stability. Through the quantification of 
 feedbacks\, closed chains of interactions\, these patterns shed light on t
 he much debated relation between complexity and stability in ecosystems.\n
