Biotic interchange in the Anthropocene: strong asymmetry in East Asian and eastern North American plant invasions

摘要

Aim Modern species invasions result in the global reshuffling of regional floras, but biogeographical biases in floristic exchanges (origin effects) are underexplored. We compared habitat-level invasion patterns in two environmentally similar regions, and ask whether plant exchanges are also similar or if one region largely invades the other.
