5 Thriving Ecosystems That Are Shocking Scientists

[@coastermania17]

SciShow: There are ecosystems in the canopies of redwood trees. Me: That makes sense. I would assume there are birds and creatures that make homes in the trees. SciShow: There are trees growing on the trees. Me: Wait, what?

[@horseenthusiast9903]

It's pretty trippy! I live in Humboldt County, and we have a lot of coastal redwoods here. If you look really hard, sometimes you can see the little trees growing off of them. Also, I like to look up and watch for the flying squirrels. Also, I've seen an albino tree in one of the redwood forests! The redwood ecosystem is fascinating, and it's a shame logging has destroyed so much of the old growth.

The Chernobyl exclusion zone is also home to a lot of Radiotrophic fungus, fungus that live in the most radioactive parts of Chernobyl (for example, inside the power plant that cause the disaster in the first place) and synthesize radiation.

[@sophierobinson2738]

Like oil-eating bacteria, yes?

[@FA-ft9sq]

So the movie Annihilation is real.

[@georgemesher8897]

​@@sophierobinson2738 These guys are really interesting, because the ability to metabolise oil is very rare. Obviously they are very useful to us, especially if current trends continue, but the evolution of oil metabolism is bizarre in itself. Why would an organism evolve the ability to metabolise a high energy substance that is stored deep underground, especially when the energy release from that fuel store typically requires oxygen?

[@TT-RR]

@@georgemesher8897 as odd as oil-eating bacteria are, I would say Radiotrophic fungus even more strange. Radiation destroys and mutates DNA in every living thing we've ever studied for science yet here is type of fungus that not only likes high levels of radiation but is completely unfazed by it side effects. this kind of goes against our understanding of radiation.

[@shogun2215]

The process of chemosynthesis is particularly interesting for people looking for extraterrestrial life. It means that a planet only needs to be geologically active to host life, energy from a star might not be necessary.

[@georgemesher8897]

Issue is, liquid water is still necessary. While some planets/moons may be able to maintain liquid water oceans without a stars energy (like Jupiter's moon Europa), we have no evidence that these liquid oceans exist, nor that they can sustain life. And on Earth, we've never found life without liquid water in some capacity. I agree that exobiologists should be using deep ocean biology and chemosynthesis as alternatives to classical ecosystems in the search for extraterrestrial life, but I feel that we need to acknowledge the evidence that we have found on Earth as well. Genuinely not trying to be argumentative, just interested in the conversation. You make an interesting point, and I wanted to offer a counterpoint :) Hope you enjoy learning about science as much as I do!

[@squeezlebub3593]

@@georgemesher8897 Well as far as we are AWARE liquid water is necessary. Because that's the only reference point we have, life on Earth. It could very well be possible that liquid water is absolutely necessary for life, but in my opinion I would be very surprised if life couldn't form on planet's with other resources. That life could have completely different methods of energy synthesis. Same as you, not being argumentative just adding my opinion.

[@jwilliams703]

Including many of the solar systems moons and and even some dwarf planets are geologically active. Life could be right on our door step. All we have to do is look.

[@XxThunderflamexX]

@@squeezlebub3593 Water has a lot of properties that make it useful for hosting living things, in particular its solubility rules allowing for lipid bilayers (though we may have to argue if something that isn't cellular can be called 'alive'). Even if it's technically possible, it probably isn't worth spending much time looking for non-aqueous life, at least until we get good enough at nanorobotics to have a decent model of how such a species would even be possible.

[@georgemesher8897]

Couldn't agree more! We have no frame of reference outside of our collective scientific experience. All we have found on Earth is carbon-based life that is dependent on liquid water, but other biological chemistry is entirely possible inside and outside of our scientific understanding. Silicon, for example, plays a similar role in chemistry to carbon under completely different conditions. Silicon-based life could thrive on planets that would be entirely inhospitable to life as we know it. On top of that, there might be many, many more modes of chemical life than we can conceive of, given our limited perspective.

I read a few years after the Chernobyl accident that in some areas close to the reactor, the radiation had essentially sterilised the environment. Although trees recovered, each autumn when they lost their leaves, there were no insects or microbes to break them down. Researchers later found a decade's worth of annual leaf shed piled up in the forests. It likely has recovered now, and the leaf litter is composting.

[@AccidentalNinja]

It occurred to me that the people who cut down the redwoods might have noticed, or had a chance to notice, some odd things in the branches, or just through they had knocked down some other trees while felling the redwood.

hydrothermal vent creatures might actually be used to clean up many waste products as well when speciffically raised. my father was the one who needed to figure out why the early computer chip making mashines didn't work well when they made them smaller and faster to produce chips, essentially he figured out the things which are behind the big proceses which companies like TSMC use now/further develop now.(in this case my father mostly was the person who figured out why things didn't work and how to make them work, since back them such things wheren't really known. for example things like a clean room being needed to get proper production or dust and humidity effecing the proces so much that even a little moist or static charge can ruin the entire proces where things they didn't know back then which my father had figured out, by deciding to use high speed microscopic(as in vieuw area, not in actual camera size) cameras and just high speed cameras to look at exactly what went wrong, he got them to lend those from some company specialized in those. even microscopic amounts of moist would ruin the entire production process since parts would stick and not position well etc.(that was just one of the many things). he actually later almost went to work at ASML since they wanted him and the company he worked got mostly shut down and taken over by those other companies after the twintowers collapsed, despite that being so far away, even in netherlands the effects where great, especially in the computer chip making industry. but the thing that makes it relevant here is that at some point they also discovered that in the tanks of concentrated cyanide with some gold particles in it, there actually had developed a species of small lobster like creatures, which actually survived in there very well. that was also quite much a new thing back then. the impressive part is that despite that being before they actually figured out that such things should be kept very clean they still didn't add in such creatures themselves, and it still was inside some company hall, so somehow those creatures mucst have come in through the air as some form of bacteria or such and evolved into those lobster like creatures that fast.

I'll bet your father had many interesting stories to tell, and loved his work. My dad was the same way about his work - he loved aircraft, especially fixed wing jets. He loved solving problems on them.

[@ted_van_loon]

@@jeanjaz jeah indeed. only in his case it was less speciffic and just solving problems on many places, even though he did a lot in that speciffic field with developing and fixing those machines. but planes are great, they would be the future if it where not for broken laws, since a well designed plane is many times more efficient and fast and safe as a average car, even those standard very old 2 to 4 people tour or stunt or general purpose planes already reached fuell efficiency over 20km/l. with modern technology and some design changes to reduce turbulence, increase efficiency and stability, as well as chances in propulsion planes could provide insane fuell efficiency. I know that in germany some people modded their drachenfliegers(hangglider) with simple rc motors and since unlike paragliders drachenfliegers actually are quite efficient when motorized, some of them could even take off from a open field by just running hard and jumping, and once in the air they could very easily stay up and go super fast. flying is one of those things people tend to know very little about and so underestimate or estimate completely wrong. for example most people assume planes are like rockets needing to hold their complete weight up with their engines constantly. but in reality with decent wings it is like a insane gear ratio making sure a well designed plane needs almost no power to stay up once they are up into the air, and planes in the air when designed properly have almost no friction or resistance compared to a normal car or such(ofcource this differs for the huge planes and such and cargo or passenger planes since they need to have tiny wings compared to their size to fit on the runway) I would love to see more flying like transport, and then especially free single person gliding transport as well, essentially just some glorified version of a old drachenflieger(I called it a hangglider before but in reality drachenfliegers where and came in many more shapes and such in the past when it was still a mostly unregulated pioneer hobby for people) essentially having a way to increase glide and stability even more and add some small motors to allow further and faster flight in all conditions while keeping it light weight, and optimally also a way to easily take them along and make them compact, so anyone willing to can just kind of fly around anywhere kind of as if they can fly themselves.

@@ted_van_loon Cool thoughts! Do drachenfliegers use wing shape for lift like fixed wing aircraft, or just updrafts?

[@ted_van_loon]

@@jeanjaz depends, drachenfliegers had many different shapes originally, back then they even already accidentally or knowingly on purpose some wings with similar properties to prandtl. some only used updrafts, but many also had special wing shapes. many of the ultralight planes(those which used sail material wings) where based on drachenfliegers, just with a seat and motor added. so you have many differences in it, essentially the main rule behind it originally was that it where typically self made or group made(before it went really commercial) glider (planes) which one can easily move around using a normal car and also light enough to move easily by hand. the hapes and profiles they used changed a lot since it kind of was second stage pioneering hobby, you have those which look like normal planes, those which look like a triangle, and some random other shapes, as well as having very different wing profiles/shapes to generate lift or only use updraft. average designs also changed depending on the place the person making it would most often go. these days the famous triangular hanglider is mostly the only one still in wide use outside of ultilights and such(so still like a glider). that is probably since they are very easy and cheap to make in comparison with many other designs and they also are very general still meaning you can use them in most conditions, not always the best but often above the avererage. and ofcource they are more easy to make safe and transporting them is more easy compared to some of the more plane like designs. the triangle model probably only really gets beaten when talking about geometric(passive) autostabilization and glide ratio, won't mention speed since they are more than fast enough. essentially drachenfliegers are just gliders and glider planes people would often make at home, they are unmotorized, and typically very light and can be taken apart easily for easy transport. it kind of began mostly with Otto Lilienthal, but after the world war it got a insane peak in people doing it due to motorized planes being banned in germany around that time, also since back then there wheren't really any seriously prohibiting laws or such regarding unmotorized planes and gliders, especially not around the lightweight ones, it was basically similar to riding a bike. it mostly ended when it was kind of made illegal/commercialized, currently you need to have a lot of very expensive licences to even fly one such gliders and many extra equipment, and the glider also needs to be labeled and licenced by speciffic companie so building your own also typically is illegal unless you have enough money to get your design tested and accepted. laws kind of ruined it. ofcource this is in west europe there are places where such things are still allowed or more allowed, I have heard that in some parts of usa you are even allowed to fly a motorized ultralight without licence

Great video!

Whale Falls... All I could think of when this segment began was Harry Nilsson's Think About Your Troubles... Part of the lyrics: ...To be eaten by some fishes Who were eaten by some fishes And swallowed by a whale Who grew so old He decomposed, ooh Doo-doo Doo-doo He died and left his body To the bottom of the ocean Now everybody knows That when a body decomposes The basic elements Are given back to the ocean And the sea does what it oughta And soon there's salty water .... 🐳🐳🐳🐳🐳

I have seen a lot of your video warning about how climate change will be bad for the Earth. But as this episode shows, no matter how bad it goes, life will find a way. The way plants and animals have done for millions of years, learning to adapt, it is still the best strategy even for humans. We should NOT FIGHT climate change but ride it out with innovation and adaptation.

I love redwood trees and I wish they loved me back

[@sdfkjgh]

@I1am2me3DuhP: Give it time, man. Those trees will eventually rescind the restraining order, once they realize they need your CO2 to survive.

[@darthmortus5702]

I never understood you guys who are into plus sized trees, smaller trees are so much tighter you know?

[@mjdally82]

Congratulations to Hank for holding off using “life finds a way” until the absolute last seconds of the video 🤩🤓

[@twocvbloke]

So, my Minecraft farm in the treetops wasn't such an insane concept after all... :P

BP of water: 100°C = 373K, and 350°C = 623K (actually about 1.67 times normal BP of water, but still pretty hot)

Dammit, beat by an hour. Of course I was.

I like the end of this video

I have no doubt that there is a unique ecosystem under my fridge.

Dear SciShow! I am glad to have stumbled upon your channel several years ago, you have inspired me to make my own channel: The Futurist Tom and my latest video, "What The World Will Look Like After the Corona Virus"
