Tiny niches and translocations: The challenge of identifying suitable recipient sites for small and immobile species
Abstract Assisted colonisation, one form of species translocation, has been proposed as a tool for helping species to track suitable conditions in a changing climate. There are considerable practical challenges associated with it, including predicting where to place translocated individuals. This pr...

Abstract Assisted colonisation, one form of species translocation, has been proposed as a tool for helping species to track suitable conditions in a changing climate.
