A team of American and British scientists has created a model, based on the ecological, geographical and evolutionary characteristics of the species to assess their level of threat. The results, published in the journal Current Biology , reveal that at least 1,000 more species are in danger. More than a thousand data-deficient amphibians are in danger of extinction, of which nearly 500 are critically endangered. “We found that more than a thousand amphibians with deficient data are in danger of extinction, and of them almost 500 are critically endangered, especially in South America and Southeast Asia,” explains Pamela González-del-Pliego, first author of the work and researcher at the University of Sheffield (UK) and Yale University (USA).

The authors also warn three species could already Guadeloupe Email Lists be extinct. “Urgent conservation actions are needed to prevent the loss of these species,” adds González-del-Pliego. According to scientists, the high number of species with insufficient data is due to high species description rates and a lag in assessment rates in the last 15 years. To predict the threat status of these species whose conservation status was unknown, the research team applied a spatial-phylogenetic statistical framework, based on the ecological, geographical and evolutionary characteristics of these species. They then compared these attributes with the risk of extinction, and thus they were able to know which ones are actually in danger of extinction. The priority, amphibians without data
The findings suggest that some of the most vulnerable species may also be the least known. However, the researchers emphasize that, thanks to this work, in some areas of the world, efforts to protect species known to be threatened could benefit endangered and data-deficient species. The findings suggest that some of the most vulnerable species may also be the least known. “In the South American jungles, the species that we know are threatened have very similar geographic distributions to species with little data that could be in danger,” says the scientist. “So if we try and conserve the areas where the threatened species are, we will also protect these other species,” he says. However, the situation in Southeast Asia or Central Africa is
