Examples of network connectivity modelled from meat ant nests: (a) complete networks are highly resilient and very costly to build; (b) a minimum spanning tree network, where the minimal number of connections are made between each node. Minimum spanning trees are cheap to build and maintain, but are vulnerable to disturbances; (c) real meat ant network. Red circles indicate nests, or nodes, and are connected by black lines, indicating trails or edges. Adapted from Cabanes et al. [18]. (Online version in colour.)
