| Abstract: | The rapid evolution of increased dispersal rate during a population's range expansion provides a unique opportunity to detect trade‐offs between dispersal and reproduction. If a high reproductive rate slows down an individual's dispersal, vanguard individuals should exhibit a lower reproductive output than conspecifics from long‐colonized areas. In the present study, we demonstrate a reduction in reproductive rate in highly dispersive invasion‐front populations of cane toads in tropical Australia. |
