Identifying hotspots of faunal data deficiency to direct urgent research and monitoring
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Data deficiency is a substantial challenge for extinction risk assessments because incomplete data means we cannot accurately identify priority protected areas for conservation. Here, we use the International Union for Conservation of Nature (IUCN) distributions of amphibians, sharks and rays, fish, mammals, birds, and reptiles to identify ...
