Invasion pathway predicts the axis of ecological niche reorganisation in freshwater crayfish

Kristian Miok, Olga N. Petko, Marko Robnik‐Šikonja, Lucian Pârvulescu

This study shows that invasive crayfish species reorganize their ecological niches along different environmental axes depending on their invasion pathway, with intercontinental invaders shifting more along climate variables and within-continent invaders showing balanced climate and topographic influences.
