I see sometimes litle bits of soil on "normal" trees but they sustain just bit of grass or tree seedling but it never cross my mind it can get to such a scale on redwoods.
I've seen trees grow on some crevices on some concrete structures. Like not small itty bitty trees but medium sized ones that have multiple branches. If I was a biologist it would be my area of study lol
There are trees that grow on rocks less than a mile from me. I swear trees can live (and grow) on just about anything. These aren't small trees either. Many of them are taller than most houses.
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?
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 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?
@@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.
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.
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!
@@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.
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.
@@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.
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 just want to see A redwood. Kinda hard in MN. Although, one of the largest white pine forests used to take up most of the state. Then humans (namely European settlers) came an cut it down. I believe most of what remains is in Lake of the Woods State Park/BWCAW (Boundary Waters Canoe Area and Wilderness) and along the Northshore of Lake Superior.
@@geekygirl2596 aw...I mean a whole bunch of redwoods were cut down too, unfortunate. Still I hope you get to visit the west coast sometime! They're really a sight to see.
I'm getting some ideas for a fantasy novel, too. Like, what about a society living on top of a giant forest, not knowing that the soil beneath their feet is less than 10 meters deep before there are ferns, then branches, and then 100+ meters nothing. They'd have stone tools, if any, live in harmony with the forest around them, and one day some people just break out of the ground.
@@proffesionalweredog7426 Yeah, but it's also fun. I get to pile up mountain ranges like they're sand, carve oceans as though they were puddles, and bring entire nations into existence with a few words. I control the fate of however many people I allow in my world, and I can wipe entire races from existence if I so choose. A church may follow their god, but even that god is nothing before my endless power. In short: Making your own world is the perfect way to let off some steam, cope with feeling powerless, or explore what it's like to be omnipotent.
@@Kartoffelkamm ive been tryna craft my own fantasy world from scratch, with my own races that i created. im even trying to craft regional cultures for this world and it is like, extremely fun but a little difficult. ive been wanting to work more on it but ive gotten busy
I remember learning about chemosynthisis in school in the 90s. It was an amazing discovery that before then people didnt think was possible. Probably one of the reasons i love all science today even tho fluid dynamics is my favorite field
Chemists knew it was possible. It was mainly other science branches that may have had trouble with the idea. It's all just rather straight forward redox reactions after all.
The Coastal Redwood forests are one of the coolest things ever. Like it seriously feels like you walked into some sort of fantasy property - I kept expecting to look up at some point and see an Elven catwalk. :D

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.
MATE, I wish people payed attention to that. But when a tree that weighs as much as a redwood is landing near you, the crash makes it hard to distinguish canopy from flying vegetation.
Here in florida there are some trees with cactus growing on them. Ive also had plants growing on the counterweight ballast of my tractor on their own. Life will find a way. 😀
otakuusa animenerd, there are cacti all over trees in Hawaii, too. They’re mostly terrestrial cacti that just got a lousy spot to germinate, but there are some species of cactus that evolved to live in trees and clamber all over them.
#1 is ultra fascinating... I like to think I know lots of things, but I had no idea that smaller trees grow on the branches of bigger trees in their canopy.... _Fascinating_
When I was a kid in Humboldt Co. CA in the 70's, the Pot Growers would find Redwoods that had fallen over and left these IMMENSE stumps that would then rot from the center and the top making a huge bowl in the stump filled with mulch that they would grow pot plants in so no one could see they were deep in the bowl of 20/30 ft tall stumps. FWIW
You just reminded me of a childhood favourite of mine. The tid pools. I have spent days in them every summer until I was 14-15. All the exiting things I observed in them!
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.
If you look them up, forgot the name, they dont really have mouths. What they do is attach themselves to the bone of the mammal and secrete an acid that breaks down the bone around it. They absorb the nutrients from that.
Life is strange and very sturdy. It can survive anywhere, provided there is life on that planet. I like learning and I like how this channel is always good at teaching. You're awesome.
This was so cool. I study the fauna in temporary bodies of water and it's always amazing to see how there's life everywhere. The iceberg ecosystem really interested me though.
I remember studying ecosystems in marine ecology 🤗 I liked Whale Fall & Mangrove swamps the best.....also, scientist also found new sharks at Whale Fall
Hank you are one of the Gifts that Keep on Giving, in these troubled times!!! Your clear diction and wonderful enthusiasm are a joy to behold!! Consider me a fan, lol.
I love this episode. I knew of the ecosystems in the canopy of the rain forests. The fact this is the case with the Redwoods give's us a glimpse into the past. Why do I feel a term paper brewing inside my brain right now? 🤣
I haven't heard of any of these. I have heard of bridges, shipwrecks and abandoned oil rigs becoming bases for coral ecosystems, life in volcanoes, and an area (near Austria?) that is an underwater tourist destination during part of the year, and a small, lush oasis at other times. The diversity of life in our world is astonishing.
Thank you for using metric units. This will hopefully help move the general public to come to know and accept it as well. After all, all imperial units are already defined in metric units.
Vey interesting video! It seems like most species are thriving while humans are stuck inside at the moment. Might have to make my own video on that angler. Thanks for the inspiration to us small science guys as always!
I think it's more likely that animals and nature don't care much about viruses. Their lives are going on as normal where ours are not. Also, maybe the earth is trying to use viruses to sort "quell" our own population growth. Grim thought, but who knows?
Those ecosystems are comprised almost exclusively of bacteria and yeasts on a human gut surface. They’re diverse within their kingdoms but not between them.
I think organisms in the chernobyl exlusion area show us how sophisticated mutation repair mechanisms are. The microorganism Deinococcus radiodurans was found in power plants in Chernobyl and it seems to thrive in areas with high radiation exposure. Since this puzzled scientists, they investigated the organism and found that it possesses a repair mechanism which connects fragmented DNA in a very efficient manner (Although I'm more biomedically oriented, I would long to make a video about this though!). Our own DNA repair mechanisms are also quite amazing though!
I was hoping for sloths! I dunno if you made a video on my favorite animal but they have whole ecosystems on their back - algae is what makes it look green, and hundreds of millions of microscopic organisms exist there, some are found no where else
I have a question I haven't yet found an answer to. Sorry if it's stupid. Do birds who live in the exclusion zone and migrate to other places carry amounts of radioactive material that can be spread out of the exclusion zone? Either directly on their feathers on through their droppings. I was wondering this especially in the context of ringing and studying birds.
People are wondering how trees are growing on top of trees. It’s pretty simple actually. You place a dirt block on the leaves then a sapling on top of it then just add bone meal!
The buttons on your shirt really stand out to me. It’s the repeating pattern on the material itself. Your shirt buttons are perfectly positioned to make the squares on the shirt pattern look like a big X. The button is exactly in the middle of the X. It stands out more the farther away you are in different sections of the video. The X is really noticeable when you are further back from the camera. Cool effect
Those redwood canopy ecosystems blew my mind. Just when you think you have a good grasp on what ecosystems are around something like this comes along. This world is amazing. 4/5
I thought so, too, but having covered the buttons, it looks like it may just be an optical illusion. Or maybe they physically point that part more toward the light.
Some extra ones are life found in geysers, inhabited by extremophile bacteria, then immediately in the cavities of underground water reservoirs, insectivore bats have defecate to a point that there is a poop layer covering the bottom of the water. I don't recall who exactly did it, but I remember a YT video from a few years ago touched upon that cool cave ecosystem.
Let's not forget about the fungi that grows inside the meltdown of nuclear reactors, which feeds on the radioactivity to create energy. It is also found that those communities of fungi have a high tendency to grow towards the center of the meltdown, where there are the highest levels of radioation. Just shows how adaptable those life-forms are.
PsychoSocialCreation, almost. The vents release heat and chemicals. Bacteria synthesize those chemicals into food and energy. A food web of many different organisms builds off of that.
All life on Earth is related, so we only have evidence of life evolving once. If it really was so amazingly likely, there would probably be more than one lineage. There are limits to everything even life. It doesn't always uh uh uh find a way.
@@letitiajeavons6333 well, of course, sending a probe to Europe to fuel the conspiracy theory that social programs work would be an example of big government wasteful spending
good video, but 300 Celsius is not 3 times 100 Celsius (as said about hydrothermal vents), since 0 Celsius is arbitrary. It would make more sense to compare using Kelvin, where those numbers would be 373 and 573.
I wanna say is was one of y'all's videos (maybe Eons, i can't remember) that talked about those hydrothermal vent biomes possibly making more biodiversity possible by eating the methane and cooling the planet, and that it could have been the first life.
4:25 NAUTILUS LIVE YES!!!! WOO!! ahem. Whale falls are nifty :D Also, I'm both disappointed and glad that you didn't go for the easy line of "life finds a way" haha
WOAH. Those redwood canopy ecosystems sound like something out of a Tolkien novel. Like, are there elves living up there, in a forest hundreds of feet above the ground? I am immediately going to have to write this into a DND campaign 😮😮😮
When he discussed icebergs at 8:12, and freshwater phytoplankton - how does that work? Did they blow in on a wind serendipitously? Were they frozen in the ice, then reactivated when the ice thawed? I wonder where they came from.
You beat me to the punch. But yeah. The fact that animals do BETTER in a literal nuclear wasteland hellhole than they do in a biome with humans should tell you something about our deleterious effect in it. And STILL the climate-change deniers will cry HOAX.
@@andresacosta5318 nope. I still love my humanity too. We just need slightly fewer of us. Nuclear war would wipe away too many. Plus many of the creatures we try to protect will struggle to adapt for a while. As human, I am simultaneously scared shitless by both yours and my own statements. Prevent nuclear war at ALL COSTS!

I thought so, too, but having covered the buttons, it looks like it may just be an optical illusion. Or maybe they physically point that part more toward the light.
Could you maybe please make a video on Randle cycle ? It's interesting (you guys can sure make it interesting)
The one about Redwoods may be the only one that was new to me, but WOAH was that one cool!
Awesome episode.
The first item makes me want to plant things in or on an oak tree of my acquaintance.
Najwa Laylah, if it’s damp enough, some epiphytes like certain ferns will happily grow there.
Just make sure they won't make your oak tree sick 😁💚🌳🌳🌳🌲🌱🌿
if we track whales, we could probably find more of the whales falls
Some extra ones are life found in geysers, inhabited by extremophile bacteria, then immediately in the cavities of underground water reservoirs, insectivore bats have defecate to a point that there is a poop layer covering the bottom of the water. I don't recall who exactly did it, but I remember a YT video from a few years ago touched upon that cool cave ecosystem.
Let's not forget about the fungi that grows inside the meltdown of nuclear reactors, which feeds on the radioactivity to create energy. It is also found that those communities of fungi have a high tendency to grow towards the center of the meltdown, where there are the highest levels of radioation. Just shows how adaptable those life-forms are.
INCREDIBLE: Vents release these organisms, organisms create energy from chemical reactions! WOAH
PsychoSocialCreation, almost. The vents release heat and chemicals. Bacteria synthesize those chemicals into food and energy. A food web of many different organisms builds off of that.
Life is opportunistic. Wherever there's a change for life, it will find a way.
At least here. NASA needs to send a probe below Europe frozen oceans.
All life on Earth is related, so we only have evidence of life evolving once. If it really was so amazingly likely, there would probably be more than one lineage. There are limits to everything even life. It doesn't always uh uh uh find a way.
Do you mean Europa?
To do that they'd probably need to get more than a fraction of a percent of the national budget. 🤔
@@patrickmccurry1563 our knowledge of planets outside of our own solar system is pretty limited, I think it's honestly too early to say that.
@@letitiajeavons6333 well, of course, sending a probe to Europe to fuel the conspiracy theory that social programs work would be an example of big government wasteful spending
good video, but 300 Celsius is not 3 times 100 Celsius (as said about hydrothermal vents), since 0 Celsius is arbitrary. It would make more sense to compare using Kelvin, where those numbers would be 373 and 573.
That was a great list!!
I wanna say is was one of y'all's videos (maybe Eons, i can't remember) that talked about those hydrothermal vent biomes possibly making more biodiversity possible by eating the methane and cooling the planet, and that it could have been the first life.
This video is one huge "Life, uh, finds a way." quote hehe
Great video!
You can hear the excitement in Hank's voice in this video
I love redwood trees and I wish they loved me back
@I1am2me3DuhP: Give it time, man. Those trees will eventually rescind the restraining order, once they realize they need your CO2 to survive.
I never understood you guys who are into plus sized trees, smaller trees are so much tighter you know?
Could y’all make a video on the microbial reefs of the Black Sea?
Hank for President!
Could you make a video addressing pop sciences effects on scientific research and public impressions.
Even if humans disappear.. life will go on. Nice one!
It's show us that there's still a lot of thińg we do not discover yet.
What a beautiful nature!!!
What about the microbiomes inside of mammalian digestion tracts?
outside ((:
videos like these remind me that hank as an environmental science masters
I wonder what weirdness would come of the unlikely but possible event of a whale fall landing right on a vent system
wow so helpful thx ;)
4:25 NAUTILUS LIVE YES!!!! WOO!!
ahem.
Whale falls are nifty :D
Also, I'm both disappointed and glad that you didn't go for the easy line of "life finds a way" haha
love nautilus live
WOAH. Those redwood canopy ecosystems sound like something out of a Tolkien novel. Like, are there elves living up there, in a forest hundreds of feet above the ground? I am immediately going to have to write this into a DND campaign 😮😮😮
So basically, there's creatures that eat farts? Get one for my Dad!
I plan to go see the Redwood Forest next Spring....
The first ecosystem in the tree tops is such a bizarre and amazing thing
Edit: they all match this is such a fantastic video
Chernobyl’s a fascinating place, the HBO series made more people interested in it
When he discussed icebergs at 8:12, and freshwater phytoplankton - how does that work? Did they blow in on a wind serendipitously? Were they frozen in the ice, then reactivated when the ice thawed? I wonder where they came from.
To some living things, a floating iceberg is an entire universe!
or a sweaty crotch? 🤣🤣🤣🤣
Life finds a way
I wish there were more pictures of trees growing in a redwood canopy.
Yami Yugi(*abridged*): *That's crazy!*
Oh Redwood trees. As if I didn't already love tree enough.
I like the end of this video
So what your saying is that its possible to get git by a falling Pine tree from the canopy in a Redwood forest.
So, my Minecraft farm in the treetops wasn't such an insane concept after all... :P
lol
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.
So interesting .
I never realized Catherine was such a good barber
You guys need to make an episode about Box jellyfish
I see ecosystems thriving in people's gutters
Moral of the story - Humans: Worse than nuclear fallout (in some cases)
@Nadesican: Well, considering that we actually _caused_ the nuclear fallout by building reactors...
You beat me to the punch. But yeah. The fact that animals do BETTER in a literal nuclear wasteland hellhole than they do in a biome with humans should tell you something about our deleterious effect in it.
And STILL the climate-change deniers will cry HOAX.
Nadesican true conservationists will call for nuclear war
@@andresacosta5318 nope. I still love my humanity too. We just need slightly fewer of us. Nuclear war would wipe away too many. Plus many of the creatures we try to protect will struggle to adapt for a while.
As human, I am simultaneously scared shitless by both yours and my own statements. Prevent nuclear war at ALL COSTS!
