Un hongo ya borró buena parte de la diversidad de los Andes, y que la sierra colombiana se salve revela qué condiciones frenan a la enfermedad. Para la Argentina, que comparte fauna y cadenas de agua con esa región, cuidar los ambientes aislados vale tanto como cuidar la especie que se ve. Un ecosistema que se salva no se improvisa: se protege antes de que haga falta.","quienFirma":"Universidad de origen de la investigación (según la fuente Phys.org)","confianza":"revisado","consulta":null},"sello":{"hash":"0e2ce89fc733592dede20a98676ec792f3e1cdbb90288ab547ff5f9347c5c845","sello":"5d080cd8aff3c512fe3b5a71e4f94be0fbfd0993c3dcb1537fde2ec7fc95630e","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6590860,"aleatorio":"739cb4168eed1a0cc0398c95170d2079057f86b7146eb865f09b24fd31847899","tiempo":"2026-10-28T03:07:00.000Z"},"nist":{"cadena":2,"pulso":2002363,"salida":"7653890124C8B7FB3C146E79C2445C53C9E40C6CD77E05142D07B353A7179172ED2B049F243E231A9DE45BF640FD35D1E8668E895EA3B4A254055AA28D02FAA1","tiempo":"2026-10-28T03:05:00.000Z"},"noAntes":"2026-10-28T03:07:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 28 03:07:04 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Researchers discover why some frogs have escaped the current amphibian mass extinction","descripcion":"Amphibians are the most threatened vertebrates on Earth, with 41% of species facing extinction. In the highlands of Central and South America, a killer fungus has wiped out much of the once-abundant amphibian diversity. Yet in the Sierra Nevada de Santa Marta, an isolated mountain range in northern Colombia, amphibians still thrive. The mountain range is home to a remarkable amphibian community of at least 48 species, including 25 found nowhere else on the planet.","pubDate":"Tue, 27 Oct 2026 21:20:01 EDT","url":"https://phys.org/news/2026-10-frogs-current-amphibian-mass-extinction.html"},"indexado":"2026-10-28T03:05:33.666Z"}}
