Structure-forming invertebrates (SFI) represent an important refuge for many demersal and benthic fishes and crustaceans. Bottom-tending fishing gear is a potential source of disturbance to SFI that is frequently mitigated through the use of marine protected areas (MPAs). Here, we examined the prevalence of SFI assemblages in the eastern Bering Sea as a function of 1) spatial policy-based protections and 2) predicted habitat disturbance. Overall the assemblage richness and prevalence of SFI increased in the MPAs in the years post-fishing closure; however, similar increases also occurred in the open areas. No significant relationship was found between overall SFI and habitat disturbance. Most SFI assemblages decreased as habitat disturbance increased except for tunicate and anemone assemblages. These results suggest that changes in assemblages is likely driven by broader spatiotemporal processes rather than solely MPA influence.
