Abstract: Identifying essential nodes in complex networks is a central problem for social, biological and ecosystems. In this talk I will discuss the topic of influencers or essential nodes in three paradigmatic cases of complex networks: biological networks, mutualistic ecosystems and social media. We will discuss the relevance of these influencers to systems characterized by (i) second order transitions like information spreading in Twitter, (ii) mutualistic ecological systems dominated by abrupt first order tipping points and (iii) biological networks dominated by positive and negative interactions and argue that these systems need a new paradigm beyond network theory to be understood.
