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.
@coldsobanoodle74078 жыл бұрын
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.)

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.

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."
@masonheipel8 жыл бұрын
***** 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.

@KainYusanagi8 жыл бұрын
Mason Heipel 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).

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.

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?

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.

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.

@@typacsk no cause animals would be better without us. Look what we do is we destroy something then fix it. 90% of the time not fixing it. So isnt it better if we didn't destroy anything

Don't hate the metaphor, that's why it's a metaphor. Additionally, being from Montana, we have learned a lot about the "wolves in Yellowstone" predicament. Not only has it affected the ecosystem within Yellowstone, but the surrounding area well, (i.e. Ranch land and national forest)

That keystone species really tied the ecosystem together, did it not?

Figured that the wolves of Yellowstone were going to be mentioned, but it was nice to learn about the other two :D Sad that I know who the host is based on the dislikes. Olivia isn't a bad host! Of course there's room for improvement, but she's newer to the team. The girl from Scishow Space improved a lot with practice in comparison to when she started. The other hosts have been doing this much longer. Keep up the good work, Olivia! :)

Are humans keystone species?
@MegaWolffreak228 жыл бұрын
ThunderGun2 No. If you take us out of the equasion of our ecosystem the ecosystem would even be better off. We have big influence, yes, but earth would he just fine without us.
@samgeorge47988 жыл бұрын
ThunderGun2 not for eney specific ecosystem but there are many individual species need humans to live. like lice house cats and lots of bacteria
@MegaWolffreak228 жыл бұрын
Sam George Lice can also live on other organisms and so can 99% of all Bacteria. Housecats (i have 2 myself) would learn to hunt in the wild again, so would dogs. All domesticated animals would just go back to their primal behaviour. So no we are not Keystones in any ecosystem. (I was also taught in class that domesticated animals are not really part of any ecosystem)

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.

Commander Shepard It's a show. On KZbin. I think looks are pretty important for a website dedicated to videos. Looks are important to mostly everyone, and especially online, where you're allowed to pick and choose what you see. How many successful KZbin 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.

Almost her vantablack shirt, but not quite. :-) I think the whole thing is that there are arches on arches, in every conceivable direction. You remove one keystone, and that arch goes, then a species near the base of that arch may function as a keystone in another arch, and so on ...
