Analyzing the role of indirect connections in empirical networks

Advanced System Analysis (ASA) Program researchers develop methods and case studies analyzing empirical networked systems from ecological to economic, energy, financial and other ones. They also analyze newly available big data sets on social networks.

Systems ecology attempts to study ecological systems in a holistic fashion. In this vein, food webs are treated as networks of nodes – species or functional groups – interacting with each other by means of predation. Such considerations motivated the development and application of the network analysis methods for quantifying effects of both direct and indirect (i.e., those involving intermediate nodes) interactions in ecological networks. Based on analyses of the matrix of stationary systems flows, these methods allow reveal ecological relationships among system components.

ASA researchers further applications of network analysis aiming to study vulnerability of food webs with respect to anthropogenic stresses. By introducing network perspective, insights regarding a more sustainable way of managing natural systems can be obtained
