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: EEH is corroborated by biomass patterns, by patterns in the structure and dynamics of carnivore, folivore, and plant communities, and by experimental results, but critical empirical evidence for or against the capacity of folivorous insects to regulate plant biomass has not yet been obtained.

TL;DR: The numerical predator-to-prey ratio advocated by Pearson (1966, 1971) might not reflect the intensity of predation, and estimates ofpredation based on identifiable prey remains found from predator scats could be far too low.

TL;DR: The observed scenario is consistent with the hypothesis that vole cycles represent a mustelid-microtine limit cycle, because cycles created by this mechanism should disappear when the productive habitats, capable of supporting resident predators, become fragmented and embedded in a vast unsuitable area.
