Thermal behaviour and the prospect spread of an invasive benthic top predator onto the Euro‐Arctic shelves
Abstract Aim A focal task for invasion biology is to identify the environmental variables and biological traits that set and underpin realised and potential habitats of invasive species. Ecophysiology provides powerful empirical knowledge that connects theory with natural phenomena and may improve t...
