Leonardo DiCaprio Instagram – A groundbreaking study unravels the science of rediscovering lost species. The study’s authors—a team of researchers across the globe, including conservationists from @rewild—found that 856 tetrapod species (four-limbed animals; mammals, birds, reptiles and amphibians) are currently lost to science. The paper also reveals what we often see with the world’s most wanted lost species: that while many species are difficult to find, new techniques and a bit of effort can result in incredible rediscoveries and conservation measures. “Everything is connected,” Christina Biggs, study co-author and Re:wild lost species officer, told @scientific_american. “Every single species does matter. It behaves in an ecosystem and fulfills a purpose within it that then underpins all of the life that we have on Earth.” Link in bio to learn more. Photo: A male Santa Marta Sabrewing.
