Experiment/Study abstract: We tested the effects of predation, competition and facilitation on the annual colonization of rocky intertidal invertebrates from 2011-2023 at 6 sites along the Oregon coast. Mid zone factorial experiments testing the interactive effects of predation (primarily by whelks), competition, and facilitation on colonizers of annually cleared plots in the mid zone at core sites (ACE = Annual Colonization Experiment). The long-term goal was to determine if whelk-prey interactions varied with environmental change. Effects (interaction strengths) of each interaction were determined at the end of each experiment (fall of each year) by calculating the difference between cage controls and predator exclusion cages (predation effect, presumably by whelks in this mid-intertidal zone), exclusion cages with mussels removed after settlement (competition effect, primarily of mussels on barnacles), and exclusion cages with barnacles removed (facilitation effect of barnacles on mussels). ACE is now in its 14th year, and results through 2023 show that strengths of each of these interaction types have varied in space and time. The relative importance of interactions on prey abundance varied among types; facilitation by barnacles on mussels was the strongest effect, followed by predation effect of whelks on sessile invertebrates, with weak effects of competition between sessile invertebrates. Barnacle and mussel colonization rate was quantified using replicated marked plots that are cleared each spring prior to initiation of heavy settlement and then photographed in fall (October-December) after abatement of settlement and growth.
