Podcast Overview

Asili, mot swahili qui signifie nature, origine, essence. Chaque semaine, un épisode pour explorer le vivant : la biologie, l'écologie, les mécanismes extraordinaires qui font que la vie existe, résiste et s'adapte. Une conversation curieuse et enthousiaste avec quelqu'un qui aime profondément ce dont elle parle ; avec de la rigueur scientifique, mais surtout avec émerveillement et curiosité. Parce qu'on ne protège que ce qu'on aime. Et on n'aime que ce qu'on a pris le temps de regarder.

Les réseaux secrets des arbres

<p>Sous chaque forêt, à quelques centimètres sous la surface, il y a un réseau invisible de fils microscopiques qui relie les arbres entre eux depuis 450 millions d&#39;années. On l&#39;appelle le Wood Wide Web. Et ce qu&#39;on y a découvert est à la fois fascinant et plus nuancé qu&#39;on ne le dit souvent.</p><p>Dans cet épisode d&#39;Asili, on plonge sous la forêt.
