Despite the disparities in size and volume of marine and freshwater realms, a strikingly
similar number of species is found in each–with 15 150 Actinopterygian fishes in fresh water …

Nursery areas are critical to the survival of many marine species, and it is widely accepted
that elasmobranch species use nursery areas where they improve species fitness. A 2007 …

The scale and drivers of marine biodiversity loss are being revealed by the International
Union for Conservation of Nature (IUCN) Red List assessment process. We present the first …

Extinctions on land are often inferred from sparse sightings over time, but this technique is ill-
suited for wide-ranging species. We develop a space-for-time approach to track the spatial …

An annotated checklist of the chondrichthyan fishes (sharks, batoids and chimaeras) of the
world is presented. As of 7 November 2015, the number of species totals 1188, comprising …

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

Over the past 4 decades there has been a growing concern for the conservation status of
elasmobranchs (sharks and rays). In 2002, the first elasmobranch species were added to …

A global survey of coral reefs reveals that overfishing is driving resident shark species
toward extinction, causing diversity deficits in reef elasmobranch (shark and ray) …

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 …

Marine protected areas (MPA s) are increasingly advocated for the conservation and
management of sharks and rays. However, substantial uncertainty remains regarding which …
