Positive plant–plant interactions expand the upper distributional limits of some vascular plant species
Abstract Biotic interactions can shape species’ distributions through their impact on species’ realized niches, potentially constraining or expanding the range of conditions under which species occur. We examine whether fine‐scale plant–plant interactions scale up to shape broad‐scale species’ distr...
