“[Fungal networks] have recently been discovered by Professor Suzanne Simard and her graduate students to connect the roots of trees and facilitate the sharing of resources in Douglas-fir forests of interior British Columbia, thereby bolstering their resilience against disturbance or stress and facilitating the establishment of new regeneration.” http://www.botanicalgarden.ubc.ca/potd/2010/03/mycorrhizal_networks.php
The use of new technology has made significant changes to shared knowledge in this particular instance through ” the use of new molecular tools that can distinguish the DNA of one fungal individual from another, or of one tree’s roots from another.” In this RLE the changes in shared knowledge would not seem in any way to undermine confidence in current shared knowledge.
