Las plantas no son completamente silenciosas. Hacen crujidos, según un estudio

Published Fri, 21 Feb 2025 18:47:08 GMT

(CNN) — Las plantas hacen sonidos que el oído humano no puede detectar, según las grabaciones realizadas en un nuevo estudio, y suenan más cuando están deshidratadas o bajo otros tipos de estrés.La investigación cuestiona radicalmente lo que la mayoría de los botánicos pensaban que sabían sobre el reino vegetal, que era considerado en gran parte silencioso. También sugiere que el mundo que nos rodea es una cacofonía de sonidos de plantas, dijo la coautora del estudio, Lilach Hadany.Hadany dijo que durante mucho tiempo fue escéptica de que las plantas fueran completamente silenciosas.“Hay tantos organismos que responden al sonido que pensé que no había una buena razón para que las plantas fueran sordas y mudas”, dijo Hadany, profesora de la Facultad de Ciencias de las Plantas y Seguridad Alimentaria y directora del programa de la Facultad George S. Wise de Ciencias de la Vida en la Universidad de Tel Aviv.Los neandertales podían escuchar y hacer los mismos sonidos q...
