  • What do gray wolves, elephants, and parrotfish have in common? They're all keystone species, which means they have an especially large impact on their habitat. SciShow explores how these animals keep their ecosystems running.

    • @kubeek
      @kubeek 7 років тому +50

      I don´t think this is beacuse of her being female. She stopped wearing so much stainless stuff, but that could have gotten her a bit of dislike with the usual watchers that is gonna stick for a while.
      Another problem I think is between her and the soundguy, where she doesn´t realy make you interestes with her diction, and the sound is so squished that it makes things a lot worse and makes me loose interest very early.
      Thus, not necesarily a gender inequality.

      @docopoper 7 років тому +6

      If Wolves can be a keystone species to Yellowstone, we are a keystone species to cities. Being a keystone species doesn't mean that if the species is gone that everything collapses forever. With the wolves gone forever Yellowstone would end up looking like something new after a while... Just like with cities and us.
      That's not to say we're doing good overall for the world or anything.

    I live in Hawaii, and as a kid out playing in the ocean, a parrotfish seized my right hand middle finger and SNAP! I had to get stitches. They're not called parrotfish for no reason, they have very sharp beaks. If you go snorkelling, you can actually hear them chomping down on the coral, it's pretty cool!

    What you didnt mention is that parrotfish droppings are sand. They cant digest the coral they ingest so they excrete the white sand which makes up the beautiful coral beaches. This makes them vital for the species that rely on the beaches, including tourists who visit the beaches, and also for the tourism related income

      I won't enter in the physical appearances controversy even if I agree with them because I think there are more important thing at play here.
      She is a terrible terrible host. It has gotten better but she is far far far away from making the video enjoyable for me. Watching a video hosted by her is a net negative in my day. She is meek, has the mannerism of a 11-year-old giving out a scientific report in from of a class, doesn't seems to be able to form a complete sentence without requiring to jump cut (I'll agree that scishow overuse jump cut but it seems way worse with her), swing her hands around and around throughout the video yet her body is awfully stiff, speak slowly like a valley girl that smoked way too much weed. She has basically 0 charisma.
      What I find the most troubling was that when Hank did an interview with her before hiring her (somehow), she was totally natural and didn't exhibit anyway of those traits. She is basically the total inverse of Emily Grably and I still don't get why she's there.
      Oh yeah... and there is the time where she totally overlooked super important anthropology concept/theories because she considered them "too racist". Yeah... no... fact and science are not racist. Unbiased opinion based on fact, research and evidence has nothing to do with racism, even if those fact highlight the traditional stereotype a race has.

    Thr reason why Olivia gets more dislikes is because she's a terrible host!!! Emily Graslie didn't have that problem when she worked for SciSho so wasn't reviled. Olivia has gotten better but she still by far the weakest host. She doesn't speak with confidence and her voice waivers like she's about to cry. Even her posture and mannerisms don't support the format. She's not an 11-year-old delivering a school report, she's a professional Internet personality. She needs to start acting like it.

      Do you honestly think she's a great host? Or even a good one? When you see her standing up there does it look like she's enjoying herself? She's obviously uncomfortable and unhappy. Now, if you are also unhappy, I can see how watching her suffer every week might make you feel connected to her. But that doesn't mean that she's good at reading copy. Or that she's energizing the community to care about the things she cares about. Which is the job of the host... And she's failing miserably.

    There is a small downside for the re population of wolves however. I have seen the numbers of mountain lions take a huge hit in their numbers since there is now major competition for food and they can still be hunted. Mountain lions are on the verge of becoming an endangered species in some areas. With wolves numbers back in the healthy range, we need to turn that same passion into saving and preserving the big cats. A start could be a temporary ban on hunting mountain lions until their numbers are better.

      CokeOr Pepsi Well in cities the deer population isn't as rampant, in forested areas where we exterminated them the deer population is destructive. Then again wolves can be dangerous to humans, but since it balances out the ecology in areas where they used to exist I wouldn't mind them.

      Wolves are harmless to humans, they are actually usually pretty afraid of that naked ape (rightfully I'd say). And even if they would attack, a healthy human would rather kill the wolf than the other way around.
      If you want to be afraid of something then be afraid of bears. Without a high impact rifle you are dead if he is hungry or in a bad mood, or just wants to play with dead things and there is absolutely no defense whatsoever. So being afraid of wolves is like being afraid of a house cat but ignoring the hungry tiger behind you.

    • @coldsobanoodle7407
      @coldsobanoodle7407 7 років тому +8

      Frank Schneider True that but in a pack they are pretty fierce. That is if you threaten their territory. There have been attacks reported albeit very few, and most with rabies... Holy crap if we could use our current understanding of genetics to alter the genetic code of a wolf to give it a rabies resistance it would be pretty much safe.... Well we still have problems with wolves eating domestic pets... And small human children... Anyways that is just natural selection! If the parents don't give a crap the wolves get free food (9/10 wolves don't recommend humans for this brand is a choking hazard for small puppies human brand is not responsible for any deaths from choking on human bones.)

    Hot tip, SciShow team - the colours in the thumbnail of this video make it look slightly "greyed out", like the colour that video thumbnails go when you've already watched them (and the word "watched" normally appears along the bottom). I had to do a double-take when I saw this video in my sub box, because for a second it seemed like I had already watched it. Wouldn't want to miss a good SciShow video just because of the thumbnail colour! If you read this, I hope it helps. DFTBA. :)

Looks are important to mostly everyone, and especially online, where you're allowed to pick and choose what you see. How many successful UA-cam channels have conventionally "ugly" hosts(that show their face)? Not a lot. How many advertisements use conventionally "ugly" people? Nearly 0. Why? Because looks are an important part of human life.

      Unfortunately, that's the term that's been in use amongst scientific communities for decades. en.wikipedia.org/wiki/Keystone_species and frankly, it DOES make sense. "While the keystone is under the least pressure of any of the stones in an arch, the arch still collapses without it."

    • @masonheipel6268
      @masonheipel6268 7 років тому +5

      ***** Hm, that's an interesting point about the pressure. I suppose that's applicable. But then, it's also true that the keystone will fall if /any/ of the stones below it are removed. It's just that the pressure of those higher up make it harder to remove the lower stones. Lol. I think the metaphor is falling apart.

      Well, if you think of it as a wide arch with big stones, sure. But imagine a tight one of small stones that are all near their crushing weight capacity, with only the keystone being large. Take out one of the smaller, different-sized stones in the arch, and it'll shift, but it won't fully collapse, either. It'll just list to the side, pressing down on the remainder of the stones on that side more and more as eventually other stones crack and shatter and fall out of the pile, until eventually the entire arch falls apart- unless more stones of any of the pre-existing types, including a re-introduction of the now-missing stone type are added to reinforce it. Sometimes it'll take many smaller stones (representing when a species' population explodes in an area to fill an ecological niche that is now empty, say due to overhunting) or other times just one single stone with some fresh mortar that needs a bit of time to cure, but is still stable as is(as when you reintroduce a species that had been extinct into the ecological framework that the arch- and the video- describes; takes a bit of time for a previously extinct population to return to a state of ecological equilibrium, after all).

    We are also a keystone. Our behavior influences on many species to every direction changing the status of them forever. So adjusting human population to a moderate degree becomes very important task. So there comes more important keystone reintroduced on stage than we are, in terms of balancing the ecological system, mosquito. Therefore mosquito should be the most important keystone in nature. We should concede our throne to mosquito.

    As someone has lived in the Caribbean, I can tell you that you left out an important detail in the parrot fish/coral reef debate. It’s shark hunting that is hurting the reefs. Sharks eat groupers. Groupers eat parrot fish. When there aren’t enough sharks, there are too many groupers eating parrot fish and this too few parrot fish. Parrot fish are not generally considered great eating-the people there fish them but not in great quantities.

      -EVERYTHING he's done has been through Executive Order, which COMPLETELY IGNORES the democratic process
      -He's not letting the government talk to the media
      -He fired the acting attorney general for not supporting his HIGHLY unconstitutional Muslim ban

      redracerb18 I know the OP was about Tesla, but Logan brought up Trump, so I was taking the opportunity to bash Trump. From there, it's only hypothesis, but I thing you thought I was talking about Tesla when I was talking about Trump and then I thought you were talking about Trump when you were actually talking about Tesla. So yes, Tesla was a revolutionary, and yes, Trump is a dicktator (and yes, I intentionally added the K every time I spelled it).

      Humans absolutely have the power to be a keystone species - After all, we have the power to create vast artificial habitats. Whether we are, however, is debatable. Many animals thrive in cities, but equally, animals suffer from loss of habitat, pollution, and the like. If we allowed or even placed more plant life in cities and made them more accessible to animals, we would certainly become a vital keystone species. But, that's up to us to actually do.

      Yes. Although we've certainly had negative effects on many ecosystems, there are others (temperate forests in Eurasia, tallgrass prairie and I think terra preta in the Americas) that have adapted to benefit from our "management." For a more modern example, there are a lot of species--native and introduced--that live at high densities in human-altered agricultural or suburban areas: deer, corvids, blackbirds, mesopredators like skunks and raccoons...
      Now the big question: is this a good or a bad thing? I really don't know if there's an answer to that.

    Olivia, you're doing great - keep it up!
    On another note, I am a bit weary about the concept of a keystone species.. I mean, there are very few species that could be removed from an ecosystem without causing some larger cascade effect. Is there a statistical relationship that really shows there is a 'disproportionate' effect for these species considering their relative abundance? I'm skeptical, and I think I'm not alone. In fact, the Smithsonian published an article about this in the summer: www.smithsonianmag.com/science-nature/shrinking-keystone-180959748/
    Been thinking recently about making a video about it... thoughts anyone?
