Multiple competitive mechanisms underlie the effects of a strong invader on early‐ to late‐seral tree seedlings

1. Certain non‐native invaders reduce the species diversity and alter the structure of natural communities by displacing native species with differing life histories, successional roles or resource requirements. Few studies have tested the potential for these ‘strong invaders’ to exert multiple mechanisms of control on natives that differ in these traits.
