More and more endangered species. According to a study published in a scientific journal Biology of communicationsalmost half of the species whose risk of extinction cannot be assessed by the International Union for Conservation of Nature (IUCN), are at risk due to lack of sufficient data.

Thanks to the algorithm, researchers have calculated that of the 7,699 species for which information is missing, nearly 4,336 of them are likely to be endangered. They are 85 % of amphibians for which information is missing, as well as 40 % of ray-finned fish, 61 % of mammals, 59 % reptiles and 62 % of insects.

The study estimates that one-third to one-half of data-deficient marine species are at risk of extinction on the world’s coasts. As for terrestrial species, they are mainly found in Central Africa, South Asia and Madagascar.

As a reminder,IUCN publishes an annual global red list endangered species. The last update was on July 21 last year and now includes 147,517 species, including 41,459 threatened species.
