species, and their population sizes, at multiple trophic levels. E. Keystone species are critical to maintaining the diversity and stability of an ecosystem. F. Identifying the interactions among species in an ecosystem and determining how species numbers and population sizes are regulated requires experiments conducted over long time periods.A key mediator of trophic cascades is body mass, as it both strongly influences and evolves in response to predator–prey interactions. Here, we use Gillespie eco-evolutionary models to explore EETCs resulting from top predator loss and mediated by body mass evolution.
