The evolution of dispersal at invasive range edges. Dispersal rate determines how rapidly invasive species expand their range. At expanding range edges, evolution consistently increases dispersal rate
Description
The evolution of dispersal at invasive range edges. Dispersal rate determines how rapidly invasive species expand their range. At expanding range edges, evolution consistently increases dispersal rate, accelerating invasion speed. But can dispersal evolution also limit range expansion? Focusing on cane toads—one of Australia’s most damaging invaders—at a newly formed arid range edge, my project will test the novel hypothesis that dispersal evolution stabilises range edges and, thus, constrains the spread of invaders. Expected outcomes include resolving longstanding questions about how evolution shapes species distributions and structures range edges—with broad benefits through the development of innovative, science-driven strategies to halt the spread of invaders..
