Abstract EN
Coral reef habitats in the Papahānaumokuākea Marine National Monument (PMNM) are characterized by abundant top-level predators such as sharks and jacks.
The predator assemblage is dominated both numerically and in biomass by giant trevally (Caranx ignobilis) and Galapagos sharks (Carcharhinus galapagensis).
A lower diversity of predatory teleosts, particularly groupers and snappers, distinguishes the PMNM from other remote, unfished atolls in the Pacific.
Most coral reef top predators are site attached to a “home” atoll, but move extensively within these atolls.
Abundances of the most common sharks and jacks are highest in atoll fore reef habitats.
Top predators within the PMNM forage on a diverse range of prey and exert top-down control over shallow-water reef fish assemblages.
Ecological models suggest ecosystem processes may be most impacted by top predators through indirect effects of predation.
Knowledge gaps are identified to guide future studies of top predators in the PMNM.
