Abstract Ecosystem responses to disturbance depend on the nature of perturbation and ecological legacies left behind, making it critical understand how climate‐driven changes in regimes modify resilience properties ecosystems. For coral reefs, recent increases severe marine heat waves now co‐occur with powerful storms, historic agent disturbance. While storms kill remove their skeletons, bleach corals but leave skeletons intact. Here, we explored material legacy dead modifies two key processes that underpin reef resilience: ability herbivores control macroalgae (spatial competitors corals), replenishment new colonies. Our findings, grounded by a major bleaching event at our long‐term study locale, revealed presence structurally complex reduced grazing turf algae ~80%. macroalgae, browsing was >40% less preferred (unpalatable) taxa, only ~10% more taxa. This enabled unpalatable reach ~45% cover 2 years. By contrast, prevented from becoming established adjacent reefs lacked skeletons. Manipulation reached after 1 year (~20%) recruitment 50%. The effect juvenile growth contingent timing settlement relative If settled directly (before colonized), enhanced colony 34%, this benefit lost if colonized once had proliferated. These findings underscore changing regime can alter ecosystem disrupting trophic competitive interactions shape post‐disturbance community dynamics.

Abstract For restoration projects conducted in environments with strong predation, effective predator mitigation can be key to the successful recruitment of habitat‐forming species, and development associated ecological communities. Predator may involve exclusion through caging, or provision protective spaces complex habitat mimics. The relative efficacy two approaches vary across environmental gradients, according predation stress. To inform most methods for oyster reef restoration, we compared community between uncaged concrete blocks, caged blocks biodegradable mimics (BESE), three tidal elevations sites eastern Australia. After 1 year, invertebrate was low at all elevations. Whereas BESE supported greater abundance richness than elevations, performance facilitating spatially variable. In subtidal, were less excluding small‐bodied mesopredatory fishes units recruitment. intertidal, where exposure fish is due emersion tide, there concrete. Synthesis applications . effectiveness used small‐scale gradients. Understanding strength predator–prey interactions local scales, identity predators, crucial designing that allow colonisation target species exclude predators.

Cryptic genetic variation is increasingly being identified in numerous coral species, with prior research indicating that different cryptic lineages can exhibit varied responses to environmental changes. This suggests a potential link between and local conditions. In this study, we investigate how communities of vary along gradients. We began by identifying within six species sampled around St. Croix, USVI based on 2b-RAD sequencing data. then analyzed associations the distributions across (i.e., “cryptic community composition”) ecoregions, or geographically distinct Our findings show depth more significant predictor composition than ecoregions most influential factor among 40 abiotic variables characterize ecoregions.
