Editor's choice: threatened species

Biodiversity is in crisis and according to some estimates tens of thousands of species disappear every year. Many others are on the verge of extinction. We can only halt this decline if we have a fundamental understanding of threatened species and are able to put in place effective conservation plans to guarantee their survival.

Following the IUCN Red List categories, this collection brings together some of the latest research on the biology and conservation efforts of a wide variety of threatened species from around the world.
