The great Redwood
tree. Tall, hearty, majestic, mighty, these are all apt descriptors, and there
are many more. But the Redwood is a dying breed, and not because it can’t stand
up to the tests of the world, quite the contrary really, the Redwood is brutally
tough. We’re the ones (as usual) that killed them all off.
With less than 1.5
million acres left in the world, these trees need our protection, now more than
ever, because it seems a strange abnormality in these trees has been under
scrutiny as of late. The albino and chimera mutations that occur in some of
these trees is a marvel to botanists and phytology enthusiasts the world over
(myself included. Yay tree nerds!)
Before we get too
far along I want to clarify something. When I say 1.5 million acres that sounds
like a lot, but when you take into consideration that the Earth is 36,819,200,000
(yes that’s 36 billion) acres, 1,500,000 acres is kind of small potatoes. That’s
similar to the scale equivalent of shoving the Redwoods off to a single prison
cell. Considering the tallest one is over 350 feet in height, that’s not cool.
We’ve talked about some
monster trees before (Cosmic Radiation + 1,250 Year Old Cherry Tree = ???) but today we’re going deeper
into the woods to see if we can’t solve a peculiar little mystery. Like just
how in the heck do you get an albino tree?
Today at TI&IT
we’re going to talk briefly about some of the cool aspects of Redwood trees and
some of the parks that protect them. We’re also going to discuss a little bit
about albinism as it relates to humans. Finally we’re going to talk about these
bizarre arboreal oddities that, like Methuselah, have hidden coordinates to
protect it from vandalism.
But first and
foremost the question you’re all probably asking.
“Now…when you say vampire…?”
Nosfera-tree
The leaves of the
albino redwood look almost plastic, but they’re very, very real. The problem
with them is, while they’re beautiful, they lack a very important ingredient
that is essential to the life of every
plant on this planet. The ability to produce chlorophyll. This is how the plant
produces energy.
These trees don’t
produce chlorophyll effectively, thereby making it impossible to get energy.
Therefore they have to vampirize their neighbors. (“I vant to suck your sap!
Bwah!”) We’ll dig deeper into that in a bit. Let’s take a quick biology lesson
first.
Plants are actually
quite remarkable. Think of them in terms of humans. (This will come in handy
later in the article.) In order for humans and other animals to function we
have to produce energy of some kind. Plants are no different in that regard. In
order for them to survive they have to be able to produce energy of their own.
So if plants and trees are like us, we can think of smaller plants like ferns
and flowers as in respect to animals and insects, and we can think of trees as
people, comparing their more complex systems to our own.
A dandelion, while
it operates on the same sort of principles as trees, has things a little
easier. A tree sometimes has to pump nutrients from the soil hundreds of feet
up into the air to get them to its leaves. A dandelion is much closer to the
ground so it needs a less complex physiology in order to accomplish this same
task.
Trees have a series
of transporters built into their biology that function much in the same way our
circulatory system does. Using what’s known as Xylem and Phloem they are able
to provide their leaves with the nutrients and water they need to stimulate the
photosynthetic process. Xylem essentially functions like veins, taking raw
nutrients and water to the leaves to be cycled through photosynthesis and
converted into sucrose and glucose (sugars) and carried to the rest of the
plant. The structure that takes the nutrient rich sap, or blood if we think
like humans, is called Phloem. Phloem works like our arteries which carry
oxygen rich blood to our extremities for our muscles and other organs to
function properly.
Xylem and Phloem
can be visible if a cross section of a tree is taken.
Xylem is
represented in the trees growth rings. The inner rings closest to the heartwood
or Pith are the functioning Xylem. As the tree grows the rings extend toward
the outer layers, this Xylem dies off and becomes non-functioning as new Xylem
forms. It isn’t useless at this stage however, not only does it tell scientists
how old a tree is it still stores vital nutrients for the rest of the tree.
Think of old Xylem like fat in people.
Phloem on the other
hand is the innermost layer of the bark. The bark is like our skin, protecting
the tree from the elements, predation, and disease. While Xylem is mostly
comprised of dead tissues and cells, Phloem is very much alive. It transports the
glucose to the roots or bulbs for storage and can move in any direction
throughout the tree provided it’s structurally feasible. Xylem is
unidirectional, meaning it can only flow upward.
*Whew!*
So now we know why
they need photosynthesis, how does it work? It’s pretty cool actually. The
plant takes in light through small vascular openings kind of like capillaries
on the leaves called Chloroplasts. Chloroplasts are responsible for producing
Chlorophyll, which is a key ingredient in converting raw nutrients and water
into sap. It also produces the trees pigmentation.
The spectrum of
light is basically the Rainbow. (ROY G. BIV. Remember him?) Red, orange,
yellow, green, blue, indigo, and violet. For one reason or another, the only
colors of light in the spectrum that plants seem to have use for are the ones on
the far left and right of the green, the blues and the reds. Green isn’t taken
in, that’s why most plants appear green, they reflect the color of light they
don’t have in them.
Chlorophyll works
like Melanin in people. It’s the factor that determines the pigmentation of the
plant. Depending on what the plant pulls in from the light spectrum to use
photosynthesis, it could range from light green, to reds and yellows, even pink
and black leaves have been noted.
So what happens
when the plant can’t utilize the light spectrum for pigmentation let alone
photosynthesis? You end up with something called albinism.
Albino Is The New
Green
Albinism, or
Achromia can strike anyone. It doesn’t matter what your racial background is.
It doesn’t care if your family’s rich or poor, old or young, skinny or fat, it’s
a recessive gene. If it’s in your bloodline, being born just becomes a crap
shoot. But what causes the disorder?
A lack of the
pigment melanin. The body is unable to produce the enzyme Tyrosinase. This
enzyme is copper containing and is directly responsible for the production of
melanin. Without this enzyme melanin cannot form within the skin, leaving the
afflicted with a ghostly pale appearance in the skin, hair, and eyes.
It isn’t just color
that’s affected by this disorder in humans and animals. Vision can be affected
as well. The eyes are highly dependent on melanin in order to function
properly. In fact, melanin is what gives eyes their wide variations in color.
The more melanin someone has in their eyes the darker the colors will be,
presenting with usually a brown or black iris. The less melanin they have the
lighter the color will be, i.e. blue or green eyes.
Melanin protects
the skin from harmful U.V. radiation by altering the pigmentation to block
excess rays that cause damaging effects. (This is why there is such a wide
array of skin color pending geographic location. Race is really just an arbitrary
term.) This same phenomena applies to the eyes. People with darker eye color
are less sensitive to light than those of us with blue eyes.
In those who suffer
from albinism, since they lack the protective melanin, their eyes are far more
susceptible to the damaging effects of ultraviolet radiation. It can cause eyes
to cross, retinal failure, or worse yet, photophobia. This is not to be
confused with heliophobia which is a goofy morbid fear of light. Photophobia isn’t
a fear but rather a physical discomfort or pain caused by the exposure of
light. In short, Heliophobics are sissies, photophobics can’t help it, it hurts.
Fortunately for
humans, we don’t photosynthesize our energy through the pores of our skin.
Plants on the other hand aren’t so fortunate.
So now we know that
albino humans can’t produce melanin and albino plants can’t produce
chloroplasts. We know that this has damaging effects on the bodies of humans
and this prevents plants from undergoing photosynthesis. Humans with albinism
can still eat and drink to produce energy, but how do plants do it?
For that we have to
get a little help from classic horror.
Vampires.
The Roots of All Evil
Alright, so vampire
trees may be a little bit misleading. They actually don’t uproot themselves at
night stalking the forest in search of stamens to bite. They’re vampiristic
actions are far more subtle than that. It all takes place away from the prying
eyes of humans. Right beneath our feet.
As we know they can’t
produce chlorophyll, which means they can’t stimulate photosynthesis, so how do
they get food? Well luckily albino redwoods still have roots. They intertwine
these roots with those of what’s called “The Parent Tree” in order to suckle
nutrients from it.
What’s more
incredible is that albino redwoods don’t appear to be growths unto themselves
but rather branches from said parent tree. They don’t grow as trees so much as
have the appearance of shrubs and bushes. Take a look at the example below.
Researchers have no
idea why these redwoods sprout these genetic mutations. Some conclude it’s an
abnormality in the genetic structure of the redwood. Genetically, redwoods are
what’s known as a hexaploid meaning they have 66 chromosomes. Humans by
contrast are diploids only containing 23. With 43 more chromosomes than us,
coupled with the fact that some of the oldest redwoods alive today date back to
the Roman Empire, this allows for a lot of variables that could result in this
genetic mutation.
What’s even more
incredible is that some of these albino redwoods present as chimeric, meaning
they have both white and green
leaves. This means that to some extent these chimera albino redwoods are
capable of producing chlorophyll and therefore living on their own, however
they are still more fragile than their full sapped redwood counterparts.
Chimera redwoods
are much rarer than their preciously numbered counterparts. Not only that, they’re
gold mines for researchers studying these trees and their genetic composition.
Since it contains both the green and the white needles on the same tree it
gives them the opportunity to study how the healthy tree operates in tandem
with the albino tree. They are strange to say the least.
What’s even
stranger is that during times of necessity, the parent tree can cut off the
sugar supply to the albino mutation, effectively killing it. But the plant does
not completely die. Redwood forests are extremely complicated in their ecology.
The root systems can span for miles, entangling with the systems of neighboring
trees, forming one gigantic networked forest. This can strengthen the trees
from high winds, floods, droughts, you name it. Now that’s a support group.
The parasitic root
system of the albino redwood is no different in this respect. While the part of
the plant above the ground withers and dies, the roots are unaffected. This is
how this arboreal apparition seems to disappear one season and reappear another
in the same spot.
Some scientists
have linked this genetic mutation to times of great stress and that
hypothetically this could be some sort of coping mechanism. On top of that the
increased number of chromosomes allows for a number of other possible genetic
mutations, so in a sense, they could be looking for anything.
Not much is known
about these trees, including their exact number. Reports range anywhere from 10
to over 500. The official number typically agreed upon is around 50. They were
discovered in 1866, and first published about in the California Academy of
Sciences Proceedings in 1866. Some published articles include elusions to their
use in sacred Native American rituals and spiritual rituals. I could not track
down a verifiable source of this information so I will only include the above
sentence with the following, I have not verified the truth of these accounts,
if someone has verification please feel free to leave it in the comments
section. I will be more than happy to paw through it.
These mysterious
trees will continue to fascinate us until we figure out exactly what it is that
makes them tick. Perhaps the albino redwood is a disease, an abnormal growth
that the parent plant has no control over. Perhaps it’s a way for the tree to
deal with environmental stressors. Or perhaps (and this is my personal theory) it’s
a way to store excess sugars for the host trees or other trees on the “network”
and is consumed before a drought or other disaster strikes because the tree
knows the excess stores will be needed.
If anyone
researching these wonders of the wild reads this article and is willing to
share, I would love to read any more information you have on these trees.
Anything that keeps atmosphere around for us to enjoy is alright by me, and
trees have been a fascination of mine since I was a young boy. After all, I
live in an area of the United States not known for its Redwoods, but I have one
growing in my backyard. That’s darned cool to me.
All I know is these
albino redwoods are beautiful, and I hope we discover thousands more of these
elusive forest ghosts. Hopefully one day I’ll get to see one in person. But for
now, I’ll settle for Google images. Thanks for reading everyone!
