Hank can you please explain this phenomenon www.reddit.com/r/confusing_perspective/comments/a0oxnt/circular_tree_branches/ I can't find any explanation for it..thanks
@@Musicswagg86 it is merely an effect of light and has nothing specifically to do with the trees themselves. It can also be observed through a badly scratched piece of glass. It has to do with the way the light is spread out radially from a central source. Any random field of thin lines between the light source and yourself such as branches or scratches in glass will have highlights in the direction of the light source and shadowing in the direction away from the light. The result are these "Halos" that appear around the light source.
"Crown shyness" might be one of the cutest things I've ever heard about trees! This video illustrates just one more thing to show what amazingly complex life trees and plants are.
@@விஷ்ணு_கார்த்திக் There are those who are rude and pushy, among every group. Of course, it is difficult to ignore them when they are trying to strangle you.
There are several of them. I'm in ecological restoration and we've done extensive research (including my university's specialized departments and published professors). We've also done the mycorrhizal and allelopathy. The results are pretty interesting - unfortunately many are published in journals that require exorbitant subscriptions - but I'm sure many are available on Google Scholar. In addition, professors all over academia are really cool and if you email them directly, they're usually more than happy to send you their papers for free, even if they were still published.
I love tree and plant episodes. I believe the 'friction between touching branches' theory the most. A few cottonwoods out by a local lake grow horizontally from the shoreline over the water and there is an almost perfectly horizontal border zone between their lower foliage and the water surface. Probably caused by fishes and agitation during high water days. But trees are incredible and, understanding the complexity their hormone systems can actually achieve, it would not surprise me at all to learn that they have some means of signalling to one another or something. Either way, it is bound to be a useful mechanism for lessening the sharing of certain fungal and bacterial infections that afflict leaves.
In my town there are these two huge old trees growing right next to each other in a field with nothing else around them. The two trees don't touch, but being so close together, they both have grown into the shape of what looks like two halves of one even larger tree. 🌳
As a Forestry student, learned some things about this stuff. When it comes to gaps, between branches, we think of it as the trees sensing their surrounding and diffrent species have diffrent range on critical point- when trees receive shock. If the other species are foreign it will cause a jump in growth for up to 5 years and slower than normal growth for 10+ years afterwards, when it's the same species, the shock is greater and both individuals slow down thier growth. The critical point is diffrent for all species, it can vary from a centimeter to almost a foot which would be pinus silvestris. This is why its better to add in a mix of other tree species to reduce this shock and boost forest resistances to diseases. In forest, all roots are usually intertwined and they do help their young and poision other spiecies, like video says. It's best seen on populus tremula, since it can multiply by roots, those might be more advanced. The poisioning isn't much, it is used to slow down others growth by a bit, but it helps young to outgrow the competitors. I'm not that good with english forestry terms so it might have sounded vague, i base this on Lithuanian forestry standarts as it is where i study for 3 years already.
There's actually a research I forgot the name, in which genetically related arabidopsis plants planted (too) close to each other move their leaves away from each other in order to let everyone get enough light, if these trees are genetically related this behavior makes perfect sense, just like animals show more alturistic behavior towards more genetically related individuals
Is it just me or do the patterns in the canopy kinda resemble the structures within leaves themselves? (Ya know, the plant veins. It's a weird word that starts with an x and gas too few vowels )
Another possible reason is that the trees are all communicating with each other though the fungal network they all share, Being the same species and the same age they have deliberately grown in a way that they are not competing with each other for sunlight or space, reducing the risk of causing damage to each other.
I thought I was the only one to notice that some trees didn’t touch each other. The cool thing is the trees that do this do not just randomly grow any which way but must on some level make a “conscious” decision which way their branches grow. There can be five or more what I call oak trees right next to each other and their multiple independent canopies cooperate with each other and make one big canopy like they’re all one tree and not one branch or leaf from different trees will touch.
I am wondering about the use of the word "conscious." The fascinating angle to me is the trees differentiating between "me" and "not-me" in regards to shading and growth. That's at least a sense of identity.😁
I just mean that by some means it identifies there is a tree there and adjust its trajectory because of it. It is not a blind sprint for light or area. It conceded that real estate instead of fighting for it. It does seem only to do it with the same type of trees. It’s like making room for your cousin at the dinner table.
In the pictures, in this video, it clearly shows this shyness within a given tree. Take a look at the major branches of the tree and notice that at the crown of each major section there is an open area there too. So the answer must include something that has nothing to do with the neighbouring trees as it happens within a given tree too.
burgersnchips Can I please have a link to a vid or article about this. I think my grandfather was involved in this. He went through a new treatment where they modified his T cells. He was the first person to survive the treatment in Brussels.
@@Calliopa_22 I expect your grandfather received the older personalised version which was mentioned in the article where they take some blood, filter out the t-cells and replicate them for that specific cancer. I hope he's OK and doing well!
Tree: "hey imma need about tree feet" Other trees: "why we gotta Treet each other this way?" Tree: "why yall treet me like a stranger bro... It's been this way" Other trees: "All tree of y'all, y'all done or you finished? I'm tryna photosynthesize" Wind: I'm going to end their whole career bruh
Might it have something to do with disease transmission? I hear when Henry Ford tried to grow his own rubber trees, they were planted close enough to touch, and when one tree got sick, they all did.
Many forests are much more social than we usually give them credit for. Trees even maintain family bonds. These trees of the same species and height are probably relatives, stemming from seeds off of the same mother. It makes sense to evolve a system that prevents one falling tree from taking it's siblings with it, even if it means each individual ends up being just a little bit smaller.
I like the theory that presents the groove of trees shared their needs collectively by using chemical signals in their shared biom, And in some species Have a more familial relationship With the older more well establu a.c had trees act as the Mother giving aid to the younger trees. And as a side note The plants you care for do since you . An Instructer I had in high school showed by using a common analog electrical tester. 1 probe in the soil closest to the main stalk the other connected to a mid branch end. Play different music Watch the meter move. It is amazing
It seems the gaps also exist between major branches of a single tree. So the cute idea that individual trees are being shy or polite is, dubious. More likely we're noticing the result of physical wear and tear than some "spooky" communication between trees.
Can you guys do a video on just how dangerous it is to shower during a thunderstorm? It just seems so impractical, and unbelievable, that there's not some kind of insulator surrounding water lines inside a house and that any current would consistently make the jump from small water droplets instead of discharging through the water nozzle to ground. It also seems unbelievable that it would travel along the fiberglass material most tubs are made of nowadays, as it's a very effective insulator. A bath I could understand, but a shower? Just doesn't make any sense to me.
I noticed after hurricanes there's a huge growth of underbrush which slowly subsides over the years as trees regain their former canopy density. The same is probably true with trees being shaded out.
German research a decade+ago mentioned a small electrical discharge between neighboring trees causing the space between crowns. Sort of a communication method...
Not related but.... Can you all make a video about starch extraction and processing methods from various plants and starches different uses? I was reading up on it today and wondered if you all had a video about just starch, but then could not find one from you all.
I believe it's due to mechanical breakage due to wind and such, along with trees of the same species chemically 'communicating' (for lack of a better term, to avoid more of said mechanical breakage than necessary. It's been proven that plants of the same species (and in some cases similar species) can influence one another's growth and behavior in the same area based on the conditions around them, to compensate for drought, parasites, fire, and other such forest conditions. Pretty cool stuff. I've been in forests that exhibited this 'crown shyness', it's pretty weird to be there but you just can't put your finger on why it's weird until you look straight up and see what's different. I've noticed it most often in forests that livestock (cattle and horses from my experience, probably others) populate relatively heavily. I don't know if that has more to do with the presence of livestock (and its manure/urine) itself, the lack of dense undergrowth due to livestock eating most of it, neither, or both. Pretty interesting.
Celina K No, these are healthy, mature hardwood forests that get PLENTY of rain and all 4 seasons. I'm in West Virginia, and the majority of my time spent in the woods has been in WV, OH, KY, PA, TN, and NC. We don't have to worry about that (yet). Cattle and horses just graze on most of the undergrowth as far as I've ever been able to gather, at least anywhere near trails or water.
Quick Questions: I am fascinated by rocket launches. 1. Aside from the possibility of tons of rocket and rocket fuel falling on you, how close could you stand to a rocket launch? 2. What is the DB level at the pad during liftoff?
maybe it helps protect against diseases or parasites that are transferred via leaf to leaf contact. or it could be related to maximizing light/leaf. or maybe they've just known their neighbors long enough to know they'd rather not...
I call it movement sensitivity.. the tree can sense where potentially damaging movement will occur. Obvious example is alongside a path or next to a road. You wont find the edges all smashed and broken.. they even make a nice little HGV pattern or a wing mirror pattern. All of these shapes have not been broken over time to remain this way. Most branches and leaves simply wont extend into danger. Simple
Not to be confused with "crowning" shyness, which is when an infant about to be born sees all the people in the delivery room, decides to be introverted, and refuses to leave the womb
What about root contact? Have they looked for allele activity down there? If the roots touch underground this may send a signal to inhibit crown width. Or perhaps it's mycorrhizal fungi particular to those trees providing the allelopathic triggers that manifest in the crown.
Another related mystery, check out how shrubs rarely touch their own branches and twigs or those of others either. Evolution or some sort of sensory reaction? I gots no idee, personally.
It seems to me that in forest communities the smallest differences are explored in the competition between individuals. Demand for light, shape, capacity and speed of growth are always different between species, even if only a little. But in a group where everyone is identical, having reached the maximum size for their species in that location and environmental conditions, growing more would be a waste of resources. I think that's it.
