Comparison of network tolerance to taxa removal based on different types of attack. The resistance of the networks to directed (left), cascading (middle) or random (right), removal of nodes was measured in non-protective E. faecalis (green line), ancestral E. faecalis (black line), E. coli OP50, P. mendocina, and protective E. faecalis (red line) networks. Nodes removal was based on their betweenness centrality (BNC) value. Loss of connectivity values range between 0 (maximum of connectivity between nodes) and 1 (total disconnection between nodes).
