From pole to pole: the potential for the Arctic seastar Asterias amurensis to invade a warming Southern Ocean
Abstract Due to climatic warming, Asterias amurensis , a keystone boreal predatory seastar that has established extensive invasive populations in southern Australia, is a potential high‐risk invader of the sub‐Antarctic and Antarctic. To assess the potential range expansion of A. amurensis to the So...
