50. Pando the Trembling Giant

MISCONCEPTION: The Blue whale is the largest organism in existence.

TRUTH: Many would say that Ant colonies count as one organism, but they are also just too small. What we are talking about now is a super-organism, and in the world of super-organisms, ant colonies are small fry.

The largest(known)  super-organism is called Pando, Latin for ‘I spread’. Pando is a tree, or not. It varies depending on your definition of a tree. Pando (a.k.a. the Trembling Giant) is a clonal colony of a single male, Quaking Aspen(Populus Tremuloides). It is located in Utah in the United States of America.

The way it works is this; when the Quaking Aspen wants to reproduce, it both flowers and produces a clone of itself. The cloning just means extending its network of roots and forcing them up through the ground, thus starting a new tree. This new tree has the same genetic makeup and even has genetic markers to say that it actually belongs to the first tree.

The new tree grows with the old one and together they establish a large root network which produces more and more Quaking Aspen, essentially causing the single tree to expand into a clonal colony with a vast root network.

Just how vast is it?Part of a larger Aspen Colony, note the people in the bottom left for a scale reference.

Normally clonal colonies are 0.1 hectares in size, Pando is 43 hectares in size, and weighs 6,000 tons. Now wait, there is more.

The trees on the surface die, the root network is the real Trembling Giant, and it does not die. It constantly sends up new shoots, renews dieing trees and stops supplying nutrients to those which are dead. The reason it cannot die is because the heart of Pando lies too far beneath the ground to be reached by the frequent forest fires. These forest fires are in fact a boon for Pando as it kills off the pesky invading conifers and frees up space for many more extensions of Pando to be sent up.

Due to this invulnerability and protection from competition the heart of Pando is considered the oldest known organism in existence. Experts pin it down to being approximately 80,00 years old. This impressive longevity makes it the oldest known living organism on our fair planet.

Quaking Aspen clones 80,000 years ago the Trembling Giant was but a lone tree living in the perfect environment for it to spread, grow, flower and produce clones. However the environment has changed so much over time that it is much less hospitable towards Quaking Aspens. Experts believe that the changes in the environment have been so pronounced that  Pando has not successfully flowered in the last 10,000 years, meaning its survival is dependent upon producing more clones and hoping for forest fires to wipe out the pesky conifers.

This is impressive but there are many more super-organisms out there, many under-analysed or even unknown. So while this is good, it is almost certain that there are other things even more impressive than this.

It’s an interesting world out there.

36. Lightning Shrooms!

FACT: Lightning, according to Mary Shelley, author of Frankenstein among other novels, is a vital ingredient for any mad scientist wishing to bring their amalgamation of dead corpse parts to life. However far fetched it may be, it now seems to have some mysterious life boosting properties.

According to the lore of Japanese farmers(I assure there is such a thing), plentiful mushroom harvests follow lightning storms. So at Iwate University in northern Japan some scientists tested this, by spending several years electrocuting various species of mushroom with artificial lightning, as you do.The results have confirmed the Japanese farming legend, mushrooms can more than double their yield when shocked with lightning

The reason lightning  causes these Frankenshrooms to multiply at an increase rate is currently unknown, however it is so successful that the scientists are currently at work producing machines for farmers that will zap a veritable cornucopia of mushrooms with lightning to increase their yields. The testing has now moved to different species and early results show that the lightning works at least partially on the following: radish, rapeseed, beans and some varieties of lily. However more studies are required to confirm this.
