Functional Ecology | Adam Devenish: Mutualistic interactions facilitate invasive species spread

Functional Ecology author Adam Devenish chats to Amelia Macho about his research article, 'Mutualistic interactions facilitate invasive species spread' Adam's study explored the impact of invasive Argentine ants on seed dispersal involving both native and invasive plants. Through field experiments comparing invaded and non-invaded areas, he observed shifts in seed dispersal patterns and examined how traits like seed size and chemical composition affected ant-seed preferences. Adam's findings, that in areas invaded by Argentine ants, seeds from invasive plants were three times more likely to be dispersed than native seeds, highlight that impact of invaders may be greater than initially perceived, driving losses in both biological and functional plant diversity.
