ABSTRACT Barnacles are a foundation species in intertidal habitats. During the Pacific Marine Heatwave (PMH), barnacle cover increased northern Gulf of Alaska (GoA); however, role pelagic larval supply this increase was unknown. Using long-term monitoring data on benthic (percent cover) and populations (nauplii cyprid concentrations), we examined potential environmental drivers (temperature, chlorophyll-a, mixed layer depth) concentration whether including at regional annual scales improved percent models two study regions GoA. In both regions, concentrations were slightly higher following PMH. Percent by (but not nauplii), effect strength varied site tidal elevation. This indicates that contributes as bottom–up driver abundance. There is little evidence direct PMH either life stage. Instead, our results may illustrate positive feedback between stages, where adult abundance concentrations, which then supplied more new recruits to benthos. As heatwaves continue occur, integrating various types can provide insights into factors influencing communities.
