Keystone Predation: What Is It, and Is It Supported by Empirical Evidence? [PDF]
Ecol EvolKeystone predation has been widely cited as a key ecological mechanism controlling community structures, but is supported by limited theoretical and experimental studies. Reviewing these studies showed keystone predation has been documented across realms, appears to be most prevalent in sessile and dispersal‐limited communities and can be modified by ...
