This is great but is we focus on heat strong corals then overpopulate reefs with them once global warming changes to cooling we may have made more heat tolerant corals but now we lost the cold tolerant ones bc we never focused on that and now spread heat toterant ones to areas cold tolerance will be more necesssary. Humans trying to play God never works out,
Love to know more of the science behind it. Does heat tolerance mean that the algae is heat tolerant, does the coral protect it, or does the coral tolerate the algae toxins? Also, if we can assume many coral will bleach and die, is there any work to preserve the species that won't survive?
to my understanding its the coral itself and not the alge, since its the coral that if under stress it will not produce what the algae needs; and the algae then leaves. These new coral strains can handle the heat stress and survive with the intact algae.
I was interpreting it as the coral cells are able to withstand whatever bad chemical the algae makes when its overheated, so the coral is able to hold on to the algae and not starve to death... but maybe its algae that doesnt produce whatever chemical that harms the coral when its hot? I still assume coral since its coral theyre selectively breeding, not algae.
There's a lot of people who work to bring corals into captivity in order to make more and protect it. Sometimes they replant coral in the wild as is, like release programs for other species in zoos, sometimes they hold onto it in hope of a better future. That may mean humans get their shit together and bring a halt to global warming and other habitat destruction, or waiting for GMO technology to advance to help the other species with resistance.
Great questions! Corals can be heat tolerant because they are genetically more tolerant, or/ and they can host algae that is more tolerant (and therefore make them more tolerant). Nature is complex, many mechanisms can happen together. Yes, with climate change many corals will bleach and die. Some species are more resilient than others (some have proteins that act as sunscreen and make they bleach less, others have ticker tissue, protecting the algae, etc) . But we also see difference in resilience among individuals of the same species. In this project, the more resilient corals of different species are being used for restoration so that when they reproduce, they can naturally repopulate the reef with tolerant corals, who will survive future bleaching events. There are scientists from other labs also trying different technologies to save the corals who might die (for example cryopreservation, where they freeze the eggs and sperm of corals, to have a biobank).
Everyone involved in this project, from the scientists to every single volunteer, are doing important work to ensure that coral reefs can thrive globally. I was unaware of the existence of heat tolerant corals and was under the impression that it was only a matter of time before all of these reefs would die off. Now if nations around the world can work together to prevent the mining of minerals off of the bottom of all oceans we could be one step closer to keeping our oceans healthy.
It does make sense since Coral are animals there bound to be some that mutated a heat tolerant gene at some point. So I'm so happy to hear that they do exist and they are doing a breeding initiative to try and help them have the best chance at survival. These kinds of project work best when you bring in the community and hope to see it progress more in the future!
Bless your team. We need this attention in the Cayman Islands. The difference within my lifetime is absolutely heartbreaking. I feel like i'm losing my home every time I go swimming and notice the differences.
Great work that realize us how extreme efforts will require if we destroyed our natural resources. Hope for the best heat resistance coral generations.
LOVE THIS! The loss of our amazing beautiful reefs is absolutely heartbreaking and makes me so angry with the human species. We need to be better to our planet, nurture and protect it at all costs. Life truly is more precious than anyone can truly appreciate.
Hence why reefs are actually doing fine relatively. There a plenty of reefs that are completely unaffected by bleaching since they are growing and remote. Australia lost a lot of reef to low tides exposing it to uv, not human related. Coral dies from hard contact, hence why touristy places see more bleaching, human caused but much more localized. Arguably the increase in rain changes salinity in bay reefs and wipes them out but this too is normal, just speed up maybe. one has to remember there are whole islands made of coral reefs, it is natural they die as they grow to form islands and move closer to surface. No one addresses this.
@@PessoaAleatoria01 it’s a fact that the earth’s temperature has changed dramatically from ice ages to heat waves. But I guess your not smart enough to pick up a book
@@quentinmanson3287 Those changes happen over millions of years. The propaganda you're sharing is created by the fossil fuel industry billionaires, BTW. They want to chug ahead, making as much money as possible while destroying the planet for non-billionaires. Showing humans don't have to destroy everything makes them look bad. 😏
Amazing! This gives me so much more hope for the future of our coral reefs and oceans. I hope this breeding program can be adapted and expanded internationally where coral grows!
Stop believing lies of people who get paid for dooming. The Great Barrier Reef was never in trouble. All the claims were exaggerated and the local scientists who stated the truth were silenced and de-funded. The seas have not warmed and have not risen any more than is normal and cyclical. Every single climate model prediction has turned out to be wildly inaccurate. Fires, droughts, and hurricanes are less common and impactful today than in the past.
Thank you, simply thank you. I adore seeing restoration efforts for these incredible habitats. And have the utmost respect for those dedicating their careers to helping them. Well done on your resilient F1's.
That is an underrated conservation tool, many endangered animals breed rather well in captivity so selective breeding to increase hardiness could be a solution.
i know coral reefs take thousands of years to form but this reminds me of a certain Greek proverb." A society grows great when old men plant trees in whose shade they shall never sit". These guys are doing a great service to humanity
Temperature stress can also be slow increase in temperature (to which they can adapt) then some violent storms that bring cold streams that cause thermal shock.
Good point as this is well documented in island bays and is much worse as it can also cause a temporary change in salinity. Luckily in bays this happens eventually anyway as the coral grows and moves to the surface causing uv exposure and death that way, eventually just adding to island's mass.
This is why I love science. My only question is how these corals react to ocean acidification bc that's the second part of the problem, as far as I understand.
our best hope is to have marine producers- algae, seagrasses, etc- simply extract the carbonic acid from the water and convert it into carbohydrates, then get sequestered into the marine sediment. in a healthy sea, more dissolved CO2 means faster plant growth, and it would be a negative feedback loop, but with pollution and other stuff going on not so much anymore.
Should be looking more into how we can got corals in the hobby back into the oceans, Most tanks are running between 26-30 degrees and when replanted into the oceans seem to do very well.
There are many thermal resilient corals in places like the Red Sea where the pH is extremely low. The problem is that increased CO2 in the air mix in the oceans and fresh water from glacier melt are making the water more acidic. The increased acidity makes it harder for sealife to build up calcium exoskeleton.
coral-bleaching is NOT a big problem in the Pacific ocean. When it comes down to the Pacific ocean, the main problem is Excessive-Sedimentation because of ships, ports and irresponsible fishermen ram using anchors, trawling equipments and ramming into coral reefs. This makes the corals suffocate and choke on this sediments. The sediments also blocks out sunlight from reaching the corals. Low water visibility directly impacts corals in destructive ways.
5:21 did Florida figure out the 100 degree coral bleaching resistance? You might want to cross breed with the other coral programs to include that for jumpstarting biodiversity.
caribbean corals that we have in florida are different species, or even different genera entirely, from indo-pacific corals. we have enough issues with indo-pacific invasives on the reef from the lionfish alone, and hawaii has plenty of invasives itself too, so we can't just transplant different species into new locations. it's gotta be done the hard way
🙏❤️🌎🌿🕊🎵🎶🎵 Thank you, PBS Nature for all humanity. I have watched many of these documentaries. Ua mau ke ea o ka aina i ka pono The life of the land is preserved in righteousness.
Very encouraging. We naturally think of tree planting, hedgerows planting, rewilding and greening deserts when it comes to aiding the climate. The seas, unfortunately, are all too easily forgotten, I think because the vast majority of us don't have the opportunity to do very much to help without opening our wallets/purses (and since that produces very little in the way of money these days, at least for many of us, we tend not to support so many projects). However, there must be immense areas that have the potential to be 'planted' - as I do remember a Sir David Attenborough wildlife programme discussing vast swathes of the ocean that are shallow, warm, yet lifeless, like an underwater desert. No seaweeds live there, only the occasional large fish will pass through. So if the same process was applied to seaweeds as here with the corals, could scientists not find plants that are able to tolerate more extreme conditions, to be planted in such zones and bring out more carbon from the sea (it's not like they would be invading another organism's domain. It may just make it more hospitable for many more to adapt). If we are trying to green deserts on land, why not under the sea too?
Your "hobby" steals coral from where it should be and is another part of the devastating effect our actions are having on these ecosystems. You shouldn't brag about aiding in destroying what's already a dying ecosystem GLOBALLY.
any information on how much more resilient are these new corals? like how much longer it took to bleach, or how high the temperature they can withstand
its so cool how this is just the same genetic manipulation weve been doing for thousands of years for food and other animals. who wouldve ever guessed we would do it to corals!
hello and thank you for the great video! and your work and education about our oceans! I breed corals myself with passion and maybe it will help to start an additional berghia snail breeding in your breeding to avoid stinging caused by aiptasia! best wishes from Germany
I would love to be part of a team to help restore the coral reefs off the coast of FL. I have a contact in my area that runs a coral farm / research facility. The next time I get to speak with him I would like to find out if there is something I could possibly do to help out those efforts. The last time I spoke with him he had just returned from FL after trying to repopulate a section of coral reef with aqua cultured corals. I was hoping to hear some sort of good news but the entire section that was introduced had died due to the water temperatures. Out of curiosity I asked what kind of temperatures they were getting to cause the die off and the water temps were 100 - 104 degrees F. The poor corals were basically boiled in bath water. I hold a scuba diving certification and have some experience diving in open water in the ocean. It was an absolute beautiful experience. I feel so fortunate and grateful to have been able to enjoy that experience of a life time.
It's great that you have the community involved ( only way to do it ) but where are all the blues, greens and colorful corals? Pretty coral gathers more interest.
I wonder if bright colors are in any way related to thermal tolerance. Everything in the hotter tanks all seem to be that "ugly" brown color, where as all the images of the reef that get planted in our head are of vibrantly colored corals.
I have this pink tabling acropora in my fishtank and I’ve done EVERYTHING to kill it ripped it out, let it basically die out but she just comes back more PINK than ever coral is very very resilient and it is alive and knows everything that goes on around its environment in the ocean, it works with algea and fish invertebrates to survive they are absolutely amazing and mean so much to me as a fish keeper and a scuba diver !
Coral existed back when the word was far hotter than it is today and will become anytime soon. Since then they adapted for a cooler world but they can adapt and programs like this will help them thrive.
Why don’t we genetically modify the algae to be more resilient to heat? How long is the genome of that algae? I know of a group of people who take in samples of mushrooms to sequence the genomes. Could we not combine these brains?
So I’m curious, usually selective breeding will bring out the traits that your selecting for, however sometimes it has unintended consequences where the new coral maybe weaker and susceptible to disease or some other issue. Has the newly bred coral been tested for any of these conditions?
As a backup and experiment to learn about coral this is great but idk how helpful this is because it's still messing with nature, in the end it's not really heat resistance what we should be artificially selecting for but adaptability to whatever may happen, temperature swings, invasive species, declining water quality, etc and there really is no substitute for natural selection but to let it do its thing by leaving it to fend for itself, like it has been doing since life happened. The problem with artificial selection for re introduction to nature is that when you select for a certain trait inadvertently you are not selecting for the own organisms adaptability to get there on their own.
It's more of a pH of the water issue than a heat issue. Carbon emissions lower the pH of the ocean and make it harder for the corals to build their structures.
I think currently heating events are still more pressing than pH, but ocean acidification will be a far more devastating cascade of destruction if we reach the tipping point (which we are on track to do still).
They've devoted their lives to this, I'm sure it has occured to them to select for/breed broadly resilient corals. We didn't get a deep dive into their whole lab but there were a lot of tanks in there with different water conditions present.
Wait but they said the Algae was the one that reacted badly to heat and was the source of the problem? Why aren't they just breeding better algae? Don't they reproduce super fast and like, in a lab?
@4:00 Wouldn't it make more sense to make the algae heat tolerant, rather than just the coral because it's the algae that leaves the coral that makes the coral die??? I found this a bit confusing.
Are corals a keystone species? In coral reefs, as the name suggests, corals are the keystone species. Stony corals, the corals that make calcium carbonate skeletons, are at the basis of reef structures. These skeletons are secreted by the coral polyps. Each year, corals grow a few millimetres or several centimetres depending on the species. What would happen if coral reefs died? If all coral reefs were to die, 25% of marine life would lose their habitat. There are roughly around 1 million different species that rely on coral reefs for food and shelter. Why is coral important? Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food, income, and protection.
Wrong. Oil, coal, natural gas, and other petroleum fuels are the root cause. Climate change and increased greenhouse gases weren't a thing until the industrial revolution. That's when many countries became dependent on fossil fuels for energy.
From the United Nations official website: *"Fossil fuels - coal, oil and gas - are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions."*
@eklectiktoni Please provide the scientific evidence that is stating such assertions. Be that as it may, the exploitation of fellow animals (disease ridden animal agriculture) is the largest consumers of fossil fuel. For example, feed crop production, pharmaceutical drugs, transport of GMO crops, transport of innocent animals, slaughterhouses, packing facilities, and the constant refrigeration for decaying flesh and other bodily fluids.
@@monicasong427 No. Just stop with your nonsense. I see a lot of people like you on TH-cam and I'm starting to wonder if this is part of some misinformation campaign to distract from big oil's huge contribution to the climate crisis. Or maybe you're just misinformed. I'll set you straight if so. And for the record, I DID provide a source. But here's some more. Yes, agriculture plays a moderate role in climate emissions. Depending on who you consult it's anywhere between 22% (IPCC) to 24% (US EPA). But that includes ALL agriculture. Livestock, crops, food for livestock, houseplants, lawn grass sod, etc. If you want GHG emissions for only food it's harder to find since most sources don't break it down that way. But the UN says food production accounts for 34%. Again, that's ALL food - meat, dairy, produce, grains, etc. That also takes into account ALL emissions associated with food - growing/raising, harvesting, processing, packaging, shipping, etc. So already this proves you 100% WRONG. Most, almost two thirds of emissions have NOTHING to do with food. If you really want to break it down by sector, most emissions come from mining, heavy industry (making machines like cars/airplanes, refining metals like steel, construction, etc) heating, cooling, and lighting of buildings, and transportation of people (car, planes, etc). If you want the numbers - the IPCC (The Intergovernmental Panel on Climate Change of the United Nations) says in 2019 total GHG per sector were: transport 15%, buildings 16%, agriculture 22%, industry 34%, and other energy sectors 12%. If you read the IPCC report on industry, it says: *"The industrial sector includes ores and minerals mining, manufacturing, construction and waste management. **_It is the largest source of global GHG and CO2 emissions,_** which include direct and indirect fuel-combustion-related emissions, emissions from industrial processes and products use, as well as from waste."* Breaking it down EVEN FURTHER, the total GHG emissions from industry in 2019 was 20,025 metric tons of CO2 equivalent. Food and tobacco only contributed 265 metric tons of CO2 equivalent. So again NO, NO, NO, NO! Food (whether plant or animal based) DOES NOT contribute even close to most GHG emissions. It is PETROLEUM PRODUCTS! Most of which are used to either provide HEATING/COOLING/ELECTRICITY for HOMES and NON-RESIDENTIAL BUILDINGS or to provide energy for INDUSTRY TO MAKE MATERIALS LIKE CONCRETE AND STEEL for buildings and vehicles. If you don't believe me, google is your friend. Just search 'what percent of global emissions are from food production?' But STOP spreading misinformation. And if you think you're right, then YOU provide a source that says most (which would be more than half - at least 51%) of GHG come from animal agriculture. I'll wait.
I strongly agree. Refilling all the world's oceans with coral by hand does not sound that effective-- especially when it will all likely die again as the consequences of climate change worsen
Test chemicals on them to see which ones are bad for coral. Water sampling around coral bleaching areas for lab analysis of chemical levels. Bleached coral chemical lab analysis. Is it also suntan lotion, saline, chemicals, warming, acidification,
Sounds good but what is the actual benefit? What's the benefit with breeding heat resistant corals in a tub when the more heat resistant corals they pick up would be breeding in the reefs anyway? In 40 years time they will only have been able to breed like 8 generations, hardly enough to create some sort of "super" heat resistant coral? So I don't really see what the difference this work would have compared to doing nothing at all or putting that effort to some other conservation method. Can someone clarify these points?
This is awesome! Well done to the researchers and locals in Hawaii for taking on this project! 🐠💙

the corals produce a slime/mucus coating, but no real testing of coating for thresholds.
Also have to deal with low tides, that's what got australia, and rain water retention that can mess up bays by changing salinity.

People have bred dogs for thousands of years already, to get specific traits. I'm glad these researchers are doing the same for coral.

I wonder if bright colors are in any way related to thermal tolerance. Everything in the hotter tanks all seem to be that "ugly" brown color, where as all the images of the reef that get planted in our head are of vibrantly colored corals.
I can’t believe I could live to see the year 2092
This is so cool!
Dam thats a lot of Aiptasia.
Great work, thank you for saving the planet.
When you find the most heat resistant Coral you've found the Coralation
Will this finally counteract coral bleaching?
I have this pink tabling acropora in my fishtank and I’ve done EVERYTHING to kill it ripped it out, let it basically die out but she just comes back more PINK than ever coral is very very resilient and it is alive and knows everything that goes on around its environment in the ocean, it works with algea and fish invertebrates to survive they are absolutely amazing and mean so much to me as a fish keeper and a scuba diver !
Coral existed back when the word was far hotter than it is today and will become anytime soon. Since then they adapted for a cooler world but they can adapt and programs like this will help them thrive.
This is pretty great but how do they combat ocean acidity from higher CO2 levels?
As I told someone last century, they will simply grow where it best suits them. Corals aren't restricted to the Tropics. Same thing for fish.
The kind of news I wanna hear about.
Why don’t we genetically modify the algae to be more resilient to heat? How long is the genome of that algae? I know of a group of people who take in samples of mushrooms to sequence the genomes. Could we not combine these brains?
as every time we try to introduce or modify species, it will end very well as always right?
Power to the Refer!
where can i get daily video updates on this project?
And the sea is gmo now. I wish a happy life and succesful survival to mr corals.
So I’m curious, usually selective breeding will bring out the traits that your selecting for, however sometimes it has unintended consequences where the new coral maybe weaker and susceptible to disease or some other issue. Has the newly bred coral been tested for any of these conditions?
As a backup and experiment to learn about coral this is great but idk how helpful this is because it's still messing with nature, in the end it's not really heat resistance what we should be artificially selecting for but adaptability to whatever may happen, temperature swings, invasive species, declining water quality, etc and there really is no substitute for natural selection but to let it do its thing by leaving it to fend for itself, like it has been doing since life happened.
The problem with artificial selection for re introduction to nature is that when you select for a certain trait inadvertently you are not selecting for the own organisms adaptability to get there on their own.
Natural selection also works
It's more of a pH of the water issue than a heat issue. Carbon emissions lower the pH of the ocean and make it harder for the corals to build their structures.
I think currently heating events are still more pressing than pH, but ocean acidification will be a far more devastating cascade of destruction if we reach the tipping point (which we are on track to do still).
They've devoted their lives to this, I'm sure it has occured to them to select for/breed broadly resilient corals. We didn't get a deep dive into their whole lab but there were a lot of tanks in there with different water conditions present.
Yes Heat Stress Species need to be encouraged by Hybridization process. But the Kelps do soak the Heat from the underwater currents.
Although they cover a very very tiny amount of the sea floor they are responsible for almost half of the oxygen present on earth
Wait but they said the Algae was the one that reacted badly to heat and was the source of the problem? Why aren't they just breeding better algae? Don't they reproduce super fast and like, in a lab?
Wait, what are those things at 2:00?! 😳
Baby corals looking for permanent place to stay
@4:00 Wouldn't it make more sense to make the algae heat tolerant, rather than just the coral because it's the algae that leaves the coral that makes the coral die??? I found this a bit confusing.
Great!
... Keystone Species!!!
Are corals a keystone species?
In coral reefs, as the name suggests, corals are the keystone species. Stony corals, the corals that make calcium carbonate skeletons, are at the basis of reef structures. These skeletons are secreted by the coral polyps. Each year, corals grow a few millimetres or several centimetres depending on the species.
What would happen if coral reefs died?
If all coral reefs were to die, 25% of marine life would lose their habitat. There are roughly around 1 million different species that rely on coral reefs for food and shelter.
Why is coral important?
Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food, income, and protection.
What about acidification?
Please I hope you're keeping your security for the corals in mind.
Que fino!!
We can’t use gene editing?
As a reefer I could've watched an hour+ long video about this.
Have you tried using techniques similar to Mossy Earths way of naturally restoring reefs?
Until we reckon with the root cause of anthropogenic GHG emissions: disease ridden animal agriculture--- this is just treating the symptoms.
Wrong. Oil, coal, natural gas, and other petroleum fuels are the root cause. Climate change and increased greenhouse gases weren't a thing until the industrial revolution. That's when many countries became dependent on fossil fuels for energy.
From the United Nations official website: *"Fossil fuels - coal, oil and gas - are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions."*
@eklectiktoni Please provide the scientific evidence that is stating such assertions.
Be that as it may, the exploitation of fellow animals (disease ridden animal agriculture) is the largest consumers of fossil fuel.
For example, feed crop production, pharmaceutical drugs, transport of GMO crops, transport of innocent animals, slaughterhouses, packing facilities, and the constant refrigeration for decaying flesh and other bodily fluids.
@@monicasong427 No. Just stop with your nonsense. I see a lot of people like you on TH-cam and I'm starting to wonder if this is part of some misinformation campaign to distract from big oil's huge contribution to the climate crisis. Or maybe you're just misinformed. I'll set you straight if so. And for the record, I DID provide a source. But here's some more.
Yes, agriculture plays a moderate role in climate emissions. Depending on who you consult it's anywhere between 22% (IPCC) to 24% (US EPA). But that includes ALL agriculture. Livestock, crops, food for livestock, houseplants, lawn grass sod, etc. If you want GHG emissions for only food it's harder to find since most sources don't break it down that way. But the UN says food production accounts for 34%. Again, that's ALL food - meat, dairy, produce, grains, etc. That also takes into account ALL emissions associated with food - growing/raising, harvesting, processing, packaging, shipping, etc. So already this proves you 100% WRONG.
Most, almost two thirds of emissions have NOTHING to do with food. If you really want to break it down by sector, most emissions come from mining, heavy industry (making machines like cars/airplanes, refining metals like steel, construction, etc) heating, cooling, and lighting of buildings, and transportation of people (car, planes, etc).
If you want the numbers - the IPCC (The Intergovernmental Panel on Climate Change of the United Nations) says in 2019 total GHG per sector were: transport 15%, buildings 16%, agriculture 22%, industry 34%, and other energy sectors 12%. If you read the IPCC report on industry, it says: *"The industrial sector includes ores and minerals mining, manufacturing, construction and waste management. **_It is the largest source of global GHG and CO2 emissions,_** which include direct and indirect fuel-combustion-related emissions, emissions from industrial processes and products use, as well as from waste."*
Breaking it down EVEN FURTHER, the total GHG emissions from industry in 2019 was 20,025 metric tons of CO2 equivalent. Food and tobacco only contributed 265 metric tons of CO2 equivalent.
So again NO, NO, NO, NO! Food (whether plant or animal based) DOES NOT contribute even close to most GHG emissions. It is PETROLEUM PRODUCTS! Most of which are used to either provide HEATING/COOLING/ELECTRICITY for HOMES and NON-RESIDENTIAL BUILDINGS or to provide energy for INDUSTRY TO MAKE MATERIALS LIKE CONCRETE AND STEEL for buildings and vehicles.
If you don't believe me, google is your friend. Just search 'what percent of global emissions are from food production?' But STOP spreading misinformation. And if you think you're right, then YOU provide a source that says most (which would be more than half - at least 51%) of GHG come from animal agriculture. I'll wait.
I strongly agree. Refilling all the world's oceans with coral by hand does not sound that effective-- especially when it will all likely die again as the consequences of climate change worsen
Test chemicals on them to see which ones are bad for coral. Water sampling around coral bleaching areas for lab analysis of chemical levels. Bleached coral chemical lab analysis. Is it also suntan lotion, saline, chemicals, warming, acidification,
Sounds good but what is the actual benefit? What's the benefit with breeding heat resistant corals in a tub when the more heat resistant corals they pick up would be breeding in the reefs anyway? In 40 years time they will only have been able to breed like 8 generations, hardly enough to create some sort of "super" heat resistant coral? So I don't really see what the difference this work would have compared to doing nothing at all or putting that effort to some other conservation method. Can someone clarify these points?
