Un estudio de genética de una región de Estados Unidos no dice todavía cómo está la fauna de la Argentina, pero deja claro que aislar poblaciones pequeñas puede debilitarlas en silencio.","quienFirma":"Universidad Estatal de Carolina del Norte","confianza":"revisado","consulta":null},"sello":{"hash":"191b264d57b2cf51a19e8543cffc3dba0f5abf200c420acd9a6adc72414a7cc2","sello":"7c343882d50c9f785a5a4485a1814d7423228e1193612126078dd0cd93cf7040","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6572630,"aleatorio":"3b61eea1a1d58138777a2ab0fdc89b64a9d43bdd34ee3b5b3b884b2e4aaad8c1","tiempo":"2026-10-21T19:12:00.000Z"},"nist":{"cadena":2,"pulso":1993520,"salida":"4E4FAE9469F450209E912CB63FA3D817A321B3FEEDE00FD0A7D2DF2BFFDF5029C28BA9D44D9B3BD08780293F7AE9EE666659770C3C6F35AB64F5F5A977F715A5","tiempo":"2026-10-21T19:11:00.000Z"},"noAntes":"2026-10-21T19:12:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 21 19:12:23 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Genetic snapshot of North Carolina black bears could improve population resilience","descripcion":"A recent genomic survey of North Carolina black bears from mountain and coastal habitats reveals distinct differences in genetic health and diversity between the populations, with coastal bears exhibiting greater genetic fragility than mountain bears.
