I would like nothing more than the proof of various cryptids, alien civilizations, even alien visitors to be found. But that proof will come only through rigorous science and objective analysis, and by holding evidence to the highest standards of scrutiny. Born in south eastern Pennsylvania, i have found myself at one time or another living in Chicago, Cleveland, Raleigh-Durham, on the island of Kaua'i and finally landed on the Olympic Peninsula of Washington State. I have turned my hand to various professions from early work in 3d graphics to historic building restoration, carpentry and log home building to working in a bronze art foundry on the WWII Veterans Memorial. Currently I am a writer, script writer and working for a non profit organization called Empowerment Through Connection which is involved in equine assisted therapy for veterans, at risk teens and women.

Yggdrasil is an immense tree that is central in Norse cosmology, in connection to which the nine worlds exist.

I know that I hung on a windy tree
nine long nights,
wounded with a spear, dedicated to Odin,
myself to myself,
on that tree of which no man knows
from where its roots run.

Maybe they weren’t so far wrong?

In a study from the Natural Environment Research Council in the UK

10 May 2013

Plants use underground fungal networks to warn their neighbours of aphid attack, UK scientists have discovered.

The study, published this week in Ecology Letters, is the first to reveal plants’ ability to communicate underground in this way.

The research, funded by a NERC studentship with Rothamsted Research, changes our understanding of the ways in which living things interact with one another. If crops can be managed in a way that exploits this natural communication channel, it could provide a new weapon in the battle against insect pests.

Scientists from the University of Aberdeen, the James Hutton Institute and Rothamsted Research grew the bean plant (Vicia faba) in groups of five. They allowed three in each group to grow underground networks of mycelia – a thread-like fungus that grows from one set of roots to another. They kept the two remaining plants free of the fungal links.

They then infested one of the plants in each group with aphids, triggering the release of a suite of chemicals designed to repel aphids but attract wasps, one of the aphid’s predators.

Remarkably, plants which were not under attack themselves, but which were connected to the victim by the underground fungal network, also began to produce the defensive chemical response. Unconnected plants didn’t mount a chemical defence, so remained vulnerable to aphid attack.

Previous research had shown that plants could communicate chemically through the air, but the researchers covered the plants with bags to rule out above-ground signalling.

“We knew that plants produce volatile chemicals when attacked, and we knew they communicate danger to each other above ground. Now we know that they communicate danger through these underground fungal networks as well. Connected plants that weren’t infested by the aphids behaved as though they were. We don’t quite know the mechanism, but it’s likely to be a chemical signal.”

“Our understanding of ecological systems has not considered the fact that plants are interconnected in this way. It could have major implications for our understanding of how one organism affects another,”

The roots of virtually all groups of plants, including important food crops such as wheat, rice, maize and barley, are colonised by symbiotic fungi.

Another of the study’s authors, Professor John Pickett of Rothamsted Research, an independent research institute strategically funded by the BBSRC, says, “Aphids affect all higher-latitude agricultural regions, including the UK, the EU, North America, and North East Asia. This research could provide a new, sustainable and natural intervention. In a field of plants that have some inducible resistance to aphids, we could use a plant that’s susceptible to aphid attack to ‘switch on’ the defence mechanism through the natural underground connection. There’s the potential to deal with other pests and diseases, in other regions, in a similar way.”

Among the oldest living organism on Earth is called Pando, also known as The Trembling Giant, a clonal colony of a single male Quaking Aspen (Populus tremuloides) determined to be a single living organism by identical genetic markers and one massive underground root system. The root system of Pando is estimated 80,000 years old. Some experts speculate that Pando’s reign since 1992 as the heaviest-known organism may be short lived. Less well-studied Quaking Aspens in Utah may be 80 hectares in extent and one million years old.

Kind of adds a whole new level to the story of a haunted forest doesn’t it?

    This sounds similar to the fiction portrayal of the animal and & plant symbiotic communications networks in the Avatar movie.
    It would seem to give added weight to some of the Gaia arguments.
    It’ll be interesting to see how this develops in professional environmentalist and environmental/land management circles.
