“…This suggests a phenomenon roughly analogous to the consumptive impacts of “keystone” predators ( sensu Paine, ; see also Valls, Coll, & Christensen, ), where relatively small numbers of individuals, through their feeding on other species, have disproportionate impacts that radiate out to impact the community as a whole. Indeed, the prototypical keystone predator, the seastar Pisaster ochraceus , impacts other community members at least in part through nonconsumptive means (Morgan, Gravem, Lipus, Grabiel, & Miner, ). Our findings complement several other recent studies demonstrating that NCEs exerted by species‐rich predator communities reflect mechanisms analogous to those leading to predator diversity effects through consumptive channels (e.g., Hatcher, Dick, & Dunn, ).…”
