TL;DR: This empirical work supports long-standing theory about the role of top-down forcing in ecosystems but also highlights the unanticipated impacts of trophic cascades on processes as diverse as the dynamics of disease, wildfire, carbon sequestration, invasive species, and biogeochemical cycles.

TL;DR: The goals for this review are to lay the groundwork on supporting services to facilitate future efforts to estimate their economic value, to highlight gaps in knowledge, and to point to future directions for additional research.

TL;DR: It is proposed that resistance to herbivores is likely to change during plant development in a non-linear fashion and the role of ontogeny should be incorporated as an important factor in new syntheses of plant defense theory.

TL;DR: A global dataset is used to investigate host range for over 7,500 insect herbivore species covering a wide taxonomic breadth and interacting with more than 2,000 species of plants in 165 families to ask whether relatively specialized and generalized herbivores represent a dichotomy rather than a continuum from few to many host families and species attacked and whether diet breadth changes with increasing plant species richness toward the tropics.
