Table E1: Ponds prioritized for bullfrog control, due to their high connectivity at the landscape level, in San Carlos, Maldonado (Uruguay). These are the priority ponds to attend to in an eradication plan; eliminating or preventing the arrival of the bullfrog would slow down the invasion process. For each pond, the geographic coordinates in UTM 21S, the invasion category of L. catesbeianus and the reason for its prioritization, are included.

Figure E1: Topological ponds network at San Carlos, Maldonado (Uruguay), according to distances related to the dispersal capacity of L. catesbeianus. The size of each node is proportional to the degree centrality value of each pond (top left). The size of each node is proportional to the value of betweenness centrality of each pond (top right). The squares represent the ponds with the topological role of connector, and the triangles represent the peripheral hubs (bottom left). In these first three, uninvaded ponds appear in blue and those invaded by L. catesbeianus, in red, orange and yellow (according to their degree of invasion, described in Methods). In the latter, the colors identify the different modules of the network. Invaded ponds appear in larger sizes (bottom right).
