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 …

Elasmobranchs (sharks, rays and skates) are among the most threatened marine
vertebrates, yet their global functional diversity remains largely unknown. Here, we use a …

Knowledge of the three-dimensional movement patterns of elasmobranchs is vital to
understand their ecological roles and exposure to anthropogenic pressures. To date …

Measures of trophic position (TP) are critical for understanding food web interactions and
human‐mediated ecosystem disturbance. Nitrogen stable isotopes (δ15N) provide a …

The impact of fishing on chondrichthyan stocks around the world is currently the focus of
considerable international concern. Most chondrichthyan populations are of low productivity …

The decline of predators in a variety of ecosystems has transformed community structure
through mesopredator release and trophic cascades. Elasmobranch fishes, one of the …

This contribution, which reviews some broad trends in human history and in the history of
fishing, argues that sustainability, however defined, rarely if ever occurred as a result of an …

Evidence for severe declines in large predatory fishes is increasing around the world.
Because of its long history of intense fishing, the Mediterranean Sea offers a unique …

The estimation of fractional trophic levels (TROPHs) is essential for the management
offisheries resources as well as for quantifyingthe ecosystem effects of fishing. We …
