And also, some indoor gardening tax... and since I have a feel you might like these, but given the fact I still didn't figure out that front page edit, let me tell you, if this hits FP, send me pictures of your hands... palms... i have an ongoing and quite lasting study of relation of hands and palms with personality...

I'd send you a pic of my hands, but I don't like the idea of you touching them.

As a high school teacher, I wish Freshmen had crown shyness. Really I'll settle for any type of affliction where they don't touch each other

Thank you, thank you, thank you! I couldn't look past the first two pictures. Seeing your post makes me feel less odd about that.

What kind of trees do this?

What trees are these? Because not all tress exemplify Crown Shyness.

Only if they're the same species. Motherfuckers will choke out other species though.

Why do trees do that? Or what causes this to happen? Wouldn't more exposed surface area for leaves only benefit the tree?
ShamnusMcfee
People don't seem to know. Could simply be that trees of similar heights growing into one another would both start to block sunlight
ShamnusMcfee
for the other, creating an energetically expensive investment of low return.
eroso
This might prevent some pests/infections from spreading as quickly as they could with contact. Evolution: Only non-touchy trees survived
eroso
There is lots what we don't know about trees. Just recently it was found out how some stronger trees help weaker ones. They communicate.

These trees are probably all male and thinking "It's only gay if our leaves touch."
mrose50
Why no content @OP? Imgur likes facts more than it like tree pics.
adriedupoldprune
Cause we don't know why the trees do what the tress do.
mrose50
Imma biologist mate (though ethology not botany). There is definitely some theories on the mechanism here. Even if not OP could have said so
adriedupoldprune
But do you know why the trees do what they do?
mrose50
As mentioned above Ethologist not Botanist. Those are as far apart you can be and still be an Ecologist. Biology covers a pretty big range.

Tried googling why this happens and here's the answer from the scientific community: dunno. https://en.wikipedia.org/wiki/Crown_shyness
donkeymoney
Those edge-leaves would be less productive due to conflict with adjacent trees. Cool how the tree figures it out though.
modicumjones
I love when things have a current status of "fuck if i know for sure". That's someones thesis defence in the making
avavilina
Might be a way to avoid getting knocked over in windy conditions? If the crowns are tangled, several trees might come down together.
Bizarkly
"As the result of abrasions and collisions, there is an induced crown shyness response." Well -- hello, Jean Baptiste LaMarck!
HelloWorldThisIsDog
I read somewhere that if they touch, the new tender leaves would get damaged when there is wind because of the other tree. But dunno
PoliticalWanderer
1. Years ago I remember hearing about certain forests that were either found to be a single organism, or where every tree was connected
PoliticalWanderer
2. underground through a massive root system. If one tree was dying it would flush all its nutrients into the roots to make others healthier
PoliticalWanderer
3. Maybe crown shyness is a similar sort "greater good" for all the trees, like by not blocking each other from sunlight or something?
Hobbes777
Hey, thanks.
TheRelevancyOfMyNameIsRelativelyIrrelevant
nah, thats easy. Even trees have their own personal space. YOU HEAR THAT JOHN? EVEN TREES LIKE THEIR OWN PERSONAL SPACE.
DaveYanakov
Speaking for the forestry community, it's due to wind action abrasion and competition for light between trees. Bigger crown means it gets >
DaveYanakov
More sugar to spend on minerals in the mycelium exchange network, allowing the tree to grow taller, resulting in more sun exposure
jinglehimerschmidt
Sounds like they don't appreciate running into each other. It's also a good way to let light in
Enoan
As an educated person in a totally unrelated field, my first guess is that it prevents parasites from spreading as quickly.
fleacollerindustry
I suspect that the motion of the tree branches hitting other tree branches have a physical sheering effect, cutting the sides b4 they grow.
TachyonCode
As one with minute gardening experience: it's probably just trying to maximize photosynthesis opportunities by avoiding leaf entanglement.
TheDivineUsersub
But wouldn't the competition for light push them to encroach on one another?
TachyonCode
I mean, the branches grow towards light. Guess where light isn't? Where those leaves already are!
TachyonCode
Different, lower levels of light are of course reflected by their neighbors, but it's obviously going to be weaker than direct sun.
TachyonCode
And as for the mention of some trees doing this only with their own kind, someone should compare their reflective index to other species'.
bugbrained
Perhaps not under, but then why wouldn't the trees compete by trying to grow their canopies over the other and close the gap? You're right..
bugbrained
..that the branches would grow toward the light, and there is all that light resource that neither tree is using! Why do you think they..
TachyonCode
It wouldn't be beneficial to their competition if they couldn't sense where to grow, after all; strongly hinting at the mechanism in play.
bugbrained
I think this is a great hypothesis. The next step would be to identify the potential parasites (or herbivores or pathogens) that the trees..
bugbrained
..are trying to avoid and see how they disperse. Anything dispersing through wind or with a vector would not be avoided with this behavior.
SlightlyRelatedToThePost
Maybe so, but the trees don't know that. We're looking to see what causes it, not the potential benefits.
avavilina
Evolutionarily they do know that. As in, the crown shy trees are less prone to getting parasites, and they survive and breed/

That still doesn't answer the question. The question is, what causes it. If I raise my arm to grab something, it goes up because of electric

Miramooke

bugbrained
The potential benefits would be what causes this, evolutionarily speaking. The trees may not "know" this, but these specific species may..
SlightlyRelatedToThePost
You're giving me an answer to the wrong question. I'm not looking for the "why" I'm looking for the "how".
bugbrained
Aaaah, I had to read your other comments to see what you were getting at. As far as lodgepole pine is concerned, it sounds like tree sway..
bugbrained
..have evolved to do this by being offspring of trees who behaved this way and were more successful in reproducing because of it.
TachyonCode
The mechanism is certainly important in reaching either conclusion, however not all adaptations passed on are beneficial to reproduction.
avavilina
Can't reply to your post on my comment due to some glitch, but they can probably sense e/o pheromones or metabolism byproducts 1/2
avavilina
and a branch sensing a critical concentration of them stops growing. 2/2
TachyonCode
Given that trees' primary survival "sense" is a sensitivity to light, I'm going to guess that neither option is correct here.
