Bunias orientalis (image) Helmholtz Centre for Environmental Research - UFZ Caption Invasive exotic plant species, such as the Turkish rocket (Bunias orientalis), are often fast-growing and competitive. They may alter ecosystems by gaining dominance, increasing productivity and replacing native plant species. The current study shows that in grassland ecosystems, native generalist herbivores such as voles -- which are usually considered as a pest -- may provide substantial resistance to plant invasions.
