Role of behavior in invasive potential

Cane toad and a map of their native/invasive distributionA variety of traits have been proposed to explain the success of an invasive species but an overarching explanation of what makes a particular species invasive has long escaped biologists. Our work combines behavioral essays, stable isotopes and niche modeling techniques to investigate a highly invasive species, the cane toad (Rhinella, marina, formerly Bufo marinus). This is an ideal species to study behavioral changes associated with the invasion process given its well-known history of introductions. Extensive research has been done on cane toads in Australia. The situation there, however, is unique since there were not native toads before the introduction of cane toads.
