Frugivory‐mediated trophic cascades: how apex predators can shape the recruitment of a fleshy‐fruited tree

open access: yesOikos, EarlyView.
The recovery of large carnivores offers unique opportunities to study their cascading impacts on plant population dynamics. Medium‐sized carnivores, both prey and seed dispersers, are suppressed by apex predators, indirectly increasing seed‐eating rodent's populations and potentially altering plant establishment.
