Homesick plants - a study on Plant-soil feedback in home and foreign soil following a latitudinal sampling gradient from Morocco to Svalbard
Plant-soil feedbacks receive increasing attention as impactors of plant performance and drivers of plant community composition. How plant-soil feedbacks act in introduction events regarding both native and foreign species is a topic requiring more research. In this aspect, two particular theories ar...

This study concludes that plant-soil feedbacks and climate may limit establishment of populations outside their native ranges, and that plant-soil feedbacks might be controlled more by positive interactions than what earlier studies have concluded.
