Biotic resistance: Exclusion of native rodent consumers releases populations of a weak invader

Formally Refereed

Abstract

Biotic resistance is a commonly invoked hypothesis to explain why most exotic plant species naturalize at low abundance. Although numerous studies have documented negative impacts of native consumers on exotic plant performance, longer-term multi-generation studies are needed to understand how native consumer damage to exotics translates to their population-level suppression over large landscapes.
