1 Global Meta-Network Figure (IMAGE) University of Maryland Caption Introduced species blur natural geographic signatures in the global network of mutualistic interactions between plants and seed dispersers. Each point represents a plant or animal species and links show interactions observed at any location. Geographic patterns emerge when visualizing only interactions among native species (a) but are blurred when interactions involving introduced species are included (b).
