Mycologists refer to fungi as ecosystem engineers because they perform essential roles. Approximately 80 percent of terrestrial plant species partner with fungi, according to a number of studies. Ectomycorrizal fungi, for example, form a dense, protective sheath around the root tips of trees, including oaks, beeches, and pines. It’s a symbiotic relationship: The fungus provides the tree with nutrients, such as phosphorus and nitrogen, from the soil, in exchange for carbohydrates produced by the trees through photosynthesis. Fungi increase the surface area of trees’ root systems, allowing them to live in nutrient-poor or even toxic conditions.
Small bands moved through Slovakia, then Transylvania (now Romania), surviving in tiny remnant groups. The decades of flight and persecution took a severe spiritual toll. By the early to mid-18th century the communal life that defined Hutteritism had effectively collapsed — the community of goods had been abandoned, and the movement was on the verge of extinction, with perhaps only a small remnant still formally identifying as Hutterite.
