\"\"<\/a>Si le probl\u00e8me de la pollution sonore\u00a0<\/span>a d\u00e9j\u00e0 fait l’objet de plusieurs alertes de la part de scientifiques, c’est une d\u00e9couverte inattendue<\/strong> qu’a r\u00e9v\u00e9l\u00e9e une \u00e9tude publi\u00e9e mercredi dans la revue de la Soci\u00e9t\u00e9 britannique d’\u00e9cologie,\u00a0Functional Ecology.<\/strong> Celle-ci d\u00e9montre que les criquets sont capables d’ajuster le volume de leur m\u00e9lodie pour couvrir le vacarme ambiant.<\/strong> Or, la chose avait d\u00e9j\u00e0 \u00e9t\u00e9 observ\u00e9e chez des oiseaux, des baleines ou encore des grenouilles mais jamais chez des insectes<\/strong> souligne la Soci\u00e9t\u00e9 britannique d’\u00e9cologie dans un communiqu\u00e9.<\/span><\/p>\n

Pour arriver \u00e0 cette conclusion, une \u00e9quipe de biologistes de l’Universit\u00e9 de Bielefeld (Allemagne), a captur\u00e9 188 sp\u00e9cimens m\u00e2les de \u00ab\u00a0criquets m\u00e9lodieux\u00a0\u00bb (Chorthippus biguttulus)<\/strong> au chant\u00a0m\u00e9tallique (produit par le frottement de leurs pattes post\u00e9rieures sur leurs ailes ant\u00e9rieures<\/strong>) caract\u00e9ristique. La moiti\u00e9 de ces insectes ont \u00e9t\u00e9 attrap\u00e9s dans des endroits calmes, et l’autre moiti\u00e9 pr\u00e8s de routes tr\u00e8s fr\u00e9quent\u00e9es. Puis les chercheurs ont \u00e9tudi\u00e9 les chants des deux groupes d’insectes. Apr\u00e8s avoir analys\u00e9 un millier d\u2019enregistrements les scientifiques ont alors constat\u00e9 que les criquets vivant au bord des routes bruyantes produisaient des sons diff\u00e9rents de leurs cong\u00e9n\u00e8res habitu\u00e9s au calme.<\/strong><\/span><\/p>\n
