Abstract

A developing concept in ecology is that broad niches predict geographical range size. Plasticity in resource use is often considered to be important for responding to novel environments, and study of species that are established across different ranges provides a model for determining the drivers of species spread and distribution. Contrasting distributions of invasive species are often associated with species-specific feeding ecology, but comparisons are rarely made for multiple taxa, spatial scales or between native and invaded ranges.
