Fascinating.

Graduate student Kevin Beiler has uncovered the extent and architecture of this network 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. He has found that all trees in dry interior Douglas-fir (Pseudotsuga menziesii var. glauca) forests are interconnected, with the largest, oldest trees serving as hubs, much like the hub of a spoked wheel, where younger trees establish within the mycorrhizal network of the old trees. Through careful experimentation, recent graduate Francois Teste determined that survival of these establishing trees was greatly enhanced when they were linked into the network of the old trees.Through the use of stable isotope tracers, he and Amanda Schoonmaker, a recent undergraduate student in Forestry, found that increased survival was associated with belowground transfer of carbon, nitrogen and water from the old trees. This research provides strong evidence that maintaining forest resilience is dependent on conserving mycorrhizal links, and that removal of hub trees could unravel the network and compromise regenerative capacity of the forests.

Reading this article, I was again reminded of Lynn Margulis and Dorion Sagan's book, Dazzle Gradually, and the Gaia hypothesis. Fascinating to think that the planet is regulating itself - and if it's a sentient organism as proposed, why wouldn't it?

A team of UK scientists have discovered a natural process that could delay, or even end, the threat of global warming.

The researchers, aboard the Royal Navy’s HMS Endurance, have found that melting icebergs off the coast of Antarctica are releasing millions of tiny particles of iron into the southern Ocean, helping to create huge ‘blooms’ of algae that absorb carbon emissions. The algae then sinks to the icy depths, effectively removing CO2 from the atmosphere for hundreds of years.

According to lead researcher, Prof. Rob Raiswell of Leeds University, “The Earth itself seems to want to save us.”
