Network evolution in novel environments

“How do ecological network dynamics mediate the response of organisms to novel environments?”

A collaborative research project designed by Shai Pilosof (Ben-Gurion University of the Negev, Israel), Manlio de Domenico (Fondazione Bruno Kessler, Italy), and James Hall (University of Liverpool, UK). Funded by Human Frontier Science Program.

Our goal is to advance understanding of how communities respond to environmental change. We are using lab experiment, ecological and evolutionary models, and multi-layer network theory to study short- and long-term changes in the dynamics of inter-species interactions and of horizontal gene transfer in small bacterial communities, as we subject these systems to various environmental perturbations.

A community of bacteria, carrying plasmids, with a network of positive and negative interactions, which changes depending on environmental conditions.
