@Tofu Kingpin you literately predicted the future of youtube comments/memes considering this is a 2 year old comment By using the Me: someone else: format
The answers to some questions Green World Hypothesis: The world is green because predators keep herbivores in check. Keystone Species: a animal that were removed from a ecosystem would effect on the ecosystem as a whole Trophic Cascades: Trophic cascade is when you have an apex predator controlling the distribution of resources, and they lead to these cascades of indirect effects lots and lots of indirect effects Hypothesis and Experimentation: Killer whales eat otters. a place called Clam Lagoon. It provided us a site that orcas could not get to. We had no problem catching about 30 animals in two or three Days. And the fact that that little population did not decline when everything else did the orcas
It makes me feel despair that so many people have lost or never had a connection to Nature. While this video has lots of facts that are “dry” relative to the experience of being in Nature. The research does provide clues on how to reverse losses of endangered species.
With All honestly, I am glad to be watching these videos, as they are quite informal, I enjoy watching them repeatedly, & I somehow do not grow bored of any of the videos! They work well as video assignments, as long as the right questions are asked!
Wonderful - clear and easy to understand for my 5th grade students, yet full of profound information from two wonderful scientists. Great film. The students were absolutely fascinated.
Leopold described the trophic cascade in his essay "Thinking Like a Mountain" before any of this work was done. What is impressive, is how well Paine and Este's work empirically validates Leopold's anecdotal description.
Jesus Christ these students in the comments are garbage. You can't watch a 20 minute video but ya'll spend hours on tiktok? This video showcases THE pioneer in intertidal ecology and an immensely important concept. Show some respect.
I'm not here because of school work or assignment, I'm here because like many people, I enjoy learning and increasing my knowledge of the world around me, bettering myself so I can make better informed decisions on how I live and how I vote to live.
I love hhmi biointeractive, I wish I had them on TV when I was growing up. I was fortunate to have Eyewitness (shows and books). Happy to have these videos now!
The Animal Farm reference is VERY MUCH intended for this video. Scientists have discovered that certain animals are the major controls for the health of the ecosystem they live in, and are therefore considered keystone species. With this in mind, it is now a fact; some animals really ARE more equal than others, and their ecosystem will literally perish without their existence.
ngl the prof asking what makes the tree green and the answer being top down regulation is the best description of the kind of trick questions college throws at you. Also my third time watching this vid in my bio major.
A key stone species is a human concept for what is being observed at that point in history given the circumstances that caused the lost of one or two predators...
Can someone please clarify? What am I missing? This gentlemen tossed these starfish back into the ocean and the ecosystem changed- ok, but why didn’t the starfish come back? Once they hit the water a second time, did they forget how to crawl back on shore?! What kept them from coming back on land? Why wouldn’t they? This is a serious inquiry and I appreciate your feedback in advance! Have a good one!
do not procrastinate, the video is interesting, Don't do it just because it's a homework, do it because you're curious about it. Don't waste time doing something you don't like.
in some ecosystems, wolves are a problem and do need humans to keep it from getting worse. especially because the sections of wild are broken up by cities and roads like never before which confuse the system as well, and force groups of animals in smaller areas. also, for every square mile of city, there are tens of miles of farm for food that you and everyone else eats, and farmers are not so wealthy that they can replace unsold stock. :) walk in peace!
Nobody killed an entire ecosystem! Paine was able to demonstrate there was such a thing as a keystone species and that removal of a keystone species impacted the biodiversity of the system.
I have a question for this video. If otters are the keystone species keeping the urchins from eating all the kelp, what is causing the Urchins to stay in the area when the kelp is gone and they have nothing to eat? Urchins can live for up to 25 years and they spawn yearly, surely that environment cannot support the population anymore if that species going unchecked right?
It stands to reason that a finely balanced system relies on the contribution of all the component parts... if each were not integral in some way, then they would disappear. I really don't see that this guy is a groundbreaker for discovering that removing a component from the system causes the system to collapse. Especially as he did it deliberately.
Most ecosystems don't behave like this, and aren't "finely balanced." Removing a random species usually has little or no effect. His discovery is that some species, "keystone species," have an outsized influence on an ecosystem relative to their abundance. To a lesser degree he supported the hypothesis about the top-down regulating role of predators generally.
It's rough... still chewing on it, but here it is :-) 6. CER Question: What happens when you remove the predator starfish from a single outcrop? For a 1 ½ years & 3 years • Claim (1 sentence- Scientifically accurate -Completely answers the question using words from the question) • Evidence - scientific data that supports the claim (use the numbers or % or fractions…) • Reason: How does evidence support - or not support- the claim? Since (reason) ___________________________________________________________ Then (then) ____________________________________________________________
Some Asian countries, like Taiwan, China, and Indonesia, to name a few, are performing this same experiment in the Pacific and Indian oceans. Longlining 90 to 100 million sharks each year, cut off their their dorsal fins, and then throw the still living sharks back into the water. That number doesn't include the 10s of millions of sharks taken whole each year. The fins used for soup and chinese "medicine", the majority are brokered thru Hong Kong.
Dynamic systems are consitently in flux people, so a key stone species is provable and disprovable according to when its observed, this is how life has sustained no matter the situation or circumstances on our planet..
The title made it seem like it was going to cover various keystone species...not only sea otters. While a fair production it was a poor and even misleading title...which means overall you get a thumbs down!
According to Wikipedia when Robert Paine was in the US Army he was "the Batallion gardener" 😄, anyone who's been in the green branches knows how rediculous that sounds. A gardener at all is WTF, let alone only Batallion level.
Me: *looking at starfish* are you a keystone specie?

My favorite part!
no one asked
Lol I had the same thought
Sean and these Biointeractive pieces are amongst the best quality anywhere. So well done.
Thanks man, loved you in 300. :)
Wait so one man killed an entire ecosystem right?
Yes 🥺🙏
Ye the tide pool kinda got rekt by mussels.
on the bright side, his subsequent results gave us knowledge about the topic so we know what to avoid now
No, he did it in a single rock, and didn't kill it, only changed it.
It was only on a section of it. The ecosystem surely recovered after he stopped removing the stars
The answers to some questions
Green World Hypothesis: The world is green because predators keep herbivores in check.
Keystone Species: a animal that were removed from a ecosystem would effect on the ecosystem as a whole
Trophic Cascades: Trophic cascade is when you have an apex predator controlling the distribution of resources, and they lead to these cascades of indirect effects lots and lots of indirect effects

Tysm! These were the exact questions I had lol
i love you
thank you! 🥹
Thank youuuu
As a former student of Dr. Estes’ wife, I was very familiar of their orca research (although in 2001 the phrase “trophic cascade” was not used).
It makes me feel despair that so many people have lost or never had a connection to Nature. While this video has lots of facts that are “dry” relative to the experience of being in Nature. The research does provide clues on how to reverse losses of endangered species.

Bro this virus and staying home is getting to my head
ecologist Robert Paine has passed away on June 13, 2016. This is around seven weeks after this video was posted. Rest in peace, star thrower 😔
school, anyone?
yup..
yup
Am I the only one who hates to watch these when you have hw but loves to watch it on my own time

The title reminded me of the quote from Animal Farm.

POV: you don't want to be here
Shhhhh, keep it down, they'll find out
I wish all my ecology lessons were this interesting. Why can't they be??
i forgot that it was homework, mindblowing as hell. ecology and nature just too beautiful to handle

It was intended as stated in his book the Serengeti rules.

nice catch😭
I'm gonna take a notebook to some forrest and start chucking squirrels and call it an experiment.
i've tried this, they bite and get upset
Excellent resource - using this in my ecology class this week. thanks

All the hunters, who say hunting wolfes is healthy for the Environment, should watch this
in some ecosystems, wolves are a problem and do need humans to keep it from getting worse. especially because the sections of wild are broken up by cities and roads like never before which confuse the system as well, and force groups of animals in smaller areas. also, for every square mile of city, there are tens of miles of farm for food that you and everyone else eats, and farmers are not so wealthy that they can replace unsold stock. :) walk in peace!

There’s water proof paper. My swim coach had some for taking attendance. She didn’t know how it worked either tho :)

I have to keep pausing the video wish there was a answer key online somewhere

Can someone tell me what happened to the otters???

Why are there any thumbs down???? Pretty straight forward folks…...
because its boring

sitting in class rn reading these comments plsss
15:09 is it just me or does that guy kinda look like Adler from COD: Cold War?
what is the role that competition plays in the relationship between muscles and other crustaceans?
this is amazing
so interesting! like this video, thank u!
before even pressing play i knew there would be otters
We must acknowledge our role in this imbalance and make amends.
oh my god this was so interesting and beautiful
