La caída en la reproducción indica que algo en el ambiente está cambiando de forma profunda, aunque el estudio no alcanza a identificar una causa única. Para el lector argentino, es un recordatorio de que las señales de deterioro ambiental muchas veces llegan primero a través de especies que casi nadie mira. El silencio de un lago puede ser el primer aviso de algo que nos afecta a todos.","quienFirma":"Birds Canada","confianza":"revisado","consulta":null},"sello":{"hash":"b631152491952547122072ae495e4efe37a53ffd66379a3b16faa62cc3e4567a","sello":"a84565a7ad1bd08bbeb0dc76738a8a3587a154953b0ab9395ce1f1c00e65f884","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6610131,"aleatorio":"389992d945afab39017c549918c727dabd34eb85094ec21cfcb806b7911ea753","tiempo":"2026-11-03T19:42:30.000Z"},"nist":{"cadena":2,"pulso":2011999,"salida":"7AB146AAB11F3DDCD096F09E03554EAA0EB43998B674BD60F464C3F9ECAAE2D65975F0F8C560740A79AEA3337CEC10CAB0DFCDC6EDC153555B28BB53E6E7F056","tiempo":"2026-11-03T19:41:00.000Z"},"noAntes":"2026-11-03T19:42:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Nov  3 19:42:38 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Silent lakes ahead? Long-term study finds common loon productivity is dropping across North America","descripcion":"The eerie call of the common loon has long been the sound of North America's northern lakes, but new research shows it may not be that way in the future. A new study led by Birds Canada analyzed breeding attempts across nine Canadian provinces and seven U.S. states. The researchers found a widespread, long-term plunge in loon chick production across their range.","pubDate":"Tue, 03 Nov 2026 14:40:12 EST","url":"https://phys.org/news/2026-11-silent-lakes-term-common-loon.html"},"indexado":"2026-11-03T19:42:30.618Z"}}
