Aim The world's islands support disproportionate levels of endemic avian biodiversity
despite suffering numerous extinctions. While intensive recent research has focused on …

Most empirical research on biological shortfalls has focused on vertebrate taxa. This is
important given many species in poorly studied groups such as invertebrates, plants, and …

We created a database of lost and rediscovered tetrapod species, identified patterns in their
distribution and factors influencing rediscovery. Tetrapod species are being lost at a faster …

Fungal conservation is gaining momentum globally, but many challenges remain. To
advance further, more data are needed on fungal diversity across space and time …

The IUCN recently coordinated the first assessment of extinction risk of the world's reptile
species. This monumental undertaking allows, for the first time, an examination of threats …

Tetrapods (amphibians, reptiles, birds, and mammals) are model systems for global
biodiversity science, but continuing data gaps, limited data standardisation, and ongoing flux …

Human-driven extinction threatens entire lineages across the Tree of Life. Here we assess
the conservation status of jawed vertebrate evolutionary history, using three policy-relevant …

The register of global extinctions of marine invertebrates in historical time is updated. Three
gastropod and one insect species are removed from the list of extinct marine species, while …

Conservation management cannot proceed in the absence of the basic ecological data
necessary to develop conservation strategies for a species. Species considered Data …

In the current biodiversity crisis, conservation efforts are often focused on extinction
prevention. However, it can be difficult to determine if a species is extinct, especially if the …
