Sharks, rays, and chimaeras (Class Chondrichthyes; herein 'sharks') are the earliest extant
jawed vertebrates and exhibit some of the greatest functional diversity of all vertebrates …

Sharks are considered the apex predator of coral reefs, but the consequences of their global
depletion are uncertain. Here we explore the ecological roles of sharks on coral reefs and …

In an era of accelerated biodiversity loss and limited conservation resources, systematic
prioritization of species and places is essential. In terrestrial vertebrates, evolutionary …

Overexploitation of large apex marine predators is widespread in the world's oceans, yet the
timing and extent of declines are poorly understood. Here we reconstruct a unique fisheries …

One third of chondrichthyan species (sharks, rays, and chimeras) are threatened with
extinction, mainly due to unsustainable fishing. Large accessible international markets for …

Sharks are charismatic predators that play a key role in most marine food webs. Their
demonstrated vulnerability to exploitation has recently turned them into flagship species in …

In ecosystems, sharks can be predators, competitors, facilitators, nutrient transporters, and
food. However, overfishing and other threats have greatly reduced shark populations …

Coastal and marine management require the evaluation of multiple environmental threats
and issues. However, there are gaps in the necessary data and poor access or …

Rays (superorder Batoidea) are the most diverse group of elasmobranchs, and many are
threatened with extinction. However, there remain areas where research on the ecology of …

Sharks are a diverse group of mobile predators that forage across varied spatial scales and
have the potential to influence food web dynamics. The ecological consequences of recent …
