Communities may be reshaped by increasing rates of human-caused species invasions and extinctions and alter the structure, dynamics, and stability of species interactions. To investigate how changes affect communities, we conducted analyses of seed dispersal networks. Networks exhibited modular and specialized structure at regional and local scales, despite interaction dissimilarity across communities, were largely dominated by introduced species, and consisted of publication interactions. Furthermore, the stability and structure of the novel networks were similar to native-dominated communities. Our findings suggest that evolutionary history that is shared isn’t a essential procedure for the emergence of complex community construction, and interaction routines may be highly conserved, regardless of species identification and environment. Species can easily become well incorporated making restoration of ecosystems harder than previously believed.
