It was a call from a reporter that first made ecologist Jason Hoeksema think things had gone too far. The journalist was asking questions about the wood wide web — the idea that trees communicate with each other through an underground fungal network — that seemed to go well beyond what Hoeksema considered to be the facts. …The idea has enchanted the public, appearing in bestselling books, films and television series. It has inspired environmental campaigners, ecology students and researchers in fields including philosophy, urban planning and electronic music. …But in the ecology community there is a groundswell of unease with the way in which the ideas are being presented in popular forums. …The dispute offers a window into how scientific ideas take shape and spread in popular culture — and raises questions about what the responsibilities of scientists are as they communicate their ideas more widely.
