the loud whispering of trees

"Water and sugar have already been shown to move from older trees into the mycelial network (they are feeding the fungi, after all), so it’s possible including young trees in the network helps establish them by providing them with food while they are still trying to stand on their own two feet; indeed, this has been demonstrated experimentally before. You can also see what this implies about only cutting the biggest trees in the forest — doing so greatly diminishes the connectedness and hence resilience of the network.

To my surprise, I discovered when researching this post that it has also been known for a while that trees of different species can communicate with and support one another via their mycorrhizae. It’s long been known that plants can communicate with unrelated species through the air; plants getting chomped by herbivores release volatile chemicals that are sensed by neighboring plants, who up their defenses pro-actively just in case. But communicating — and even sharing resources — through mutual root fungi was news to me."

um tema mais que fascinante, no blog da national geographic. e que diz muito sobre o vício humano de dividir e reordenar usado como método não só de investigação mas também de transmissão de conhecimentos e de organização do mundo. nos mais pequenos gestos, naqueles quintais que as mulheres velhas mantêm com vasos de hortenses ou de amores-perfeitos e que os reformados alinham alfaces num lado, batatas do outro. gosto da espiral de aromáticas dos permaculturistas. os humanos e a geometria, uma atracção fatal. na geometria julgamos ver o dedo divino, desde bach a mandelbrot. dividir para conseguir ver e perder assim o essencial. (ainda estou influenciada pela última produção la féria para crianças).
