Understanding how environmental and human pressures impact the temporal stability of fish community biomass on shallow reefs is essential for effective conservation management. These influence directly, by affecting species’ asynchrony in fluctuations. However, their effects may also indirectly depend functional traits species composing community, which remains poorly understood. Here, we examine both direct indirect, trait-mediated variability impacts 215 Australian reefs. communities span a 10-degree sea surface temperature (SST) gradient have been monitored over 14 years. Our results indicate higher tropical owing to trait diversity redundancy colder, temperate mean trophic level. Human impacts, through negative diversity, were main destabilizing factor biomass. Temporal change SST destabilized while increasing level communities. Overall, our findings show that comprehensive analysis multiple facets crucial better understand forecast long-term marine ecosystems under global change.
