Using species distribution models to inform IUCN Red List assessments

red - an R package to facilitate species red list assessments according to the IUCN criteria

The International Union for the Conservation of Nature Red List is the most useful database of species that are at risk of extinction worldwide, as it relies on a number of objective criteria and is now widely adopted. The R package red - IUCN Redlisting Tools - performs a number of spatial analyses based on either observed occurrences or estimated ranges. Functions include calculating Extent o...

The Iucn Red List of Threatened Speciestm

Polar Bears (Ursus maritimus) are facing a range of threats that might impact their future population status (see section Threats below). The IUCN Polar Bear Specialist Group (PBSG) regards loss of sea-ice habitat due to climate warming as the most serious threat to future Polar Bear survival. We therefore based our Red List assessment on this threat factor only, recognizing that sea-ice condit...

Biotelemetry and biologging in endangered species research and animal conservation: relevance to regional, national, and IUCN Red List threat assessments

The current biodiversity crisis is characterized by the decline and extinction of numerous animal populations and species world-wide. To aid in understanding the threats and causes of population decline and the assessment of endangerment status of a species, conservation scientists and practitioners are increasingly relying on remote assessments using biotelemetry (radio telemetry, acoustic tel...
