    Landscape agricultural simplification correlates positively with the spatial distribution of a specialist yet negatively with a generalist pest

    Agricultural expansion at the cost of natural or semi-natural habitats is simplifying human-dominated landscapes. As croplands provide a large resource of food to herbivores, pest damage may increase, but such...
