Community Ecology: Feel the Love - Crash Course Ecology #4

[@DoctorWitten]

"biology is all about sex and not dying." I love Crash Course.

[@clashman208]

How old r u now doctor witten

[@piyadathanasumpun892]

Who got assigned to this while in quarantine?

[@da_lyga9123]

@Yado Lina lol

[@fellascallmethedrink]

I did.

[@aidenbell4803]

Yado Lina my school has two thirty minute assignments a week so for pap biology we watch these videos then take a quiz/test

[@dianagibson1472]

I'm a bio teacher assigning this right now :)

[@ffandrewd2986]

Me. Lmao

[@CombinedYT15]

I can't understand him when he talks too fast. Thanks dude for the subtitles, really appreciate it.

[@peterfinch448]

I wouldn't be able to bear school without Hank ;-; Best person on the planet atm

[@midgey50]

The story about the warblers coexisting and finding ways to live around each other's needs to avoid competition is really beautiful and made me a little teary.

[@savannahpehrs7]

I can't believe you guys! Haters, Back off! Hank DOES know what he is talking about, look it up, and he makes it so you don't have to spend an hour learning it. So if you don't like it, don't watch it, but you don't have to be rude.

[@NorthernKayakAngler]

Thank you for your videos.Since discovering crash course, my grade went from a B to an A. Your examples are easy to remember and your charisma helps me to remember details.

Queen of Generalization....

[@taniam3037]

It really depends on what you major in to be honest. If you have a degree in gender studies for example, then that statement will most likely apply to you whereas if you have an engineering degree,for example, it's less likely

[@inademv]

I watch these as background noise. I've taken the courses and remember the content well but it's pleasurable to hear it all again in a more casual atmosphere and in a much much more enjoyable manner.

[@shortypenguin]

Hank, kneeling outdoors was such a cliche science show host thing to do. We nerds are so proud of you.

[@Onychoprion27]

Hank Green: Campaigning to get "meh" a valid scientific measurement since 2012.

[@AlexanderGailson]

Thank you, Hank, for not going into the controversy of weird scientist who do not believe in competition. I hear about it non-stop in my ecology class -.-

[@arobbo28]

I'm glad crash course is doing ecology, as I find it much easier (and more fun) to watch than crash course biology. It means I can now watch Hank's videos as well as John's :)

[@TarunKumar-en8si]

Awesome explanation, for the first time in my life I am finding ecology interesting. Keep up the good work and ignore the morons crying about pronunciations.

[@maximiliencosme8914]

Wow, tough to understand as I'm french (yeah, french people and english you know...) BUT KEEP THE SUBTITLES AVAILABLE ! By the way, wonderful illustrations (images and jokes !) and the content is crystal clear so keep it up, we need more courses like that on the internet and particularly in ecology and evolution ! Now let's push the complexity further and you will be my first-channel-to-check everyday for the rest of my Master (in ecology, of course ^^) ;)

[@JustAnotherMudblood]

I got to watch this is Bio class today and I nearly crapped myself when Hank poped up. My teacher thought i was crazy

[@numnutz1000]

As someone who enjoys studying economics, I think ecology is so very similar when you think about it.

[@zl13hallyuforever9]

When I made that comment two months ago, almost every visible comment was about watching these videos for school. Hence my feeling of aloneness at the time xp I'm glad to see there are many of us who are interested in the subject matter ^^

[@anggeodacrem7100]

Ending up in different job. Realized niche. That's some harsh reality

[@Flapinski]

You can tell the birds in the background of the intro are layover sounds because every scene they switch, all the audio but the birds are cut. Not sure why i recognized this but i feel kinda proud.

[@vandini8185]

While you were teaching by the sunflowers Hank sir, I suddenly thought of the hunter gatherers who started farming 1,2000 years ago and how they learnt and struggled. And now here we are - teaching millions across the world about nutrient competition by transferring millions of images into the atmosphere as internet signal. MY GOD. I had a proud tear in my eye, even though my 14 years on Earth make a practically non-existent time in our history. :) Don't you agree that we indeed should change our Gregorian calender to 12017, as Kurgesagt suggests? Thank you once again, for this video. You crack me right up.

[@fuzzheadwriter]

I'm so glad there is a biography in this episode. They were my favorite part of the biology course.

[@BritaniaANDPrussia]

Thanks!! I have a bio test in two days. This has helped immensely.

[@EthanNin0]

The king of Fundamental Niches? DAISYWORLD

[@sumitrapokhrel5838]

Nice video, you speak faster than anyone but clearly. Thank you really helpful

[@FrankstaPasta]

Busy doing my lab report. Was actually praying for some new Hank to cheer me up and WOOP! this just got uploaded :D :D :D

[@ondreibazant-fabre2164]

Great work! Didn't know that much about the Niche concept. You forgot to emphasize that commensalism and mutualism are forms of Symbiosis and that there's also parasitism.

[@SheilaJohnsonINC]

l love all of the videos... thank you for your teaching! Way cool.

[@loveesTokioHotel]

I love hank so much. I started watching vlogbrothers to warm up. Learning is fun. YAY!

[@NeirinElixir]

I had about a dozen replies with expletives or saying I was simply wrong. Yours was the only one that actually explained. I've gone through college level chem and only ever heard it pronounced aluminum (that's without the i) except in bbc videos (at which everyone in class laughed). "Aluminium" is also dinged in spell check for me and I got dinged for it once in a lab writeup. I'm sorry that makes me a bad person.

[@BrantAxt]

I stop my homework... to learn... Keep it up crashcourse!!

[@MabelSabel]

this is quite helpful since I have an AP biology test on ecology this Thursday so it is a nice review, keep up the amazing work Hank :D

[@IsaHasNothing2do]

watching hank at school, in biology class, best class ever!!!

[@TheSilverMoon5]

love this show, im currently studying environmental biology and these videos are a summary of what ive been learning all semester :)

[@QuantumCraziness]

Yesss please physics crash course!

[@UrbanPanic]

Ecology and economics are not intrinsically opposed as intuition suggests. Academically, they both describe the distribution of limited resources among potentially unlimited wants. One can essentially model economics as a special case of ecology with a focus on Homo sapiens. The trick to reconciling the two is realizing that not all competition is a zero sum game, then finding a point where economic and environmental health can be sustained. Ignoring either will be disastrous for the other.

[@j4shortee]

Definitely enjoying CC Ecology! Keep it up.

[@Bwkjam]

By looking at nature we can better understand ourselves. Animals don't have inhibitions that would hold most humans back so by looking at them we can try to see the world through a more simple and easier to understand veiw.

[@Nerdbraska]

I LOVE THESE VIDEOS. You make these so exclusive. Idea for when you get to succession (because, let's face it, you will)- TERRAFORMING. Terraforming is like, the ultimate succession.

[@MrUnder30seconds]

great video, great info, great humour.

[@peregrination3643]

While everyone else worries about the pronunciation of niche, I'm curious about the pronunciation of mycorrhizae. Scientific names for plant families or insect suborders also get me--every instructor says these differently. But I guess that's allowed for a dead language. Besides, once a foreign word is adopted into another language, the rules change. It's like how octopus can be octopi, octopuses, or octopodes. If you just want the English plural, octopuses is technically correct. Therefore, "neesh" and "nitch" are both valid.

[@OddWoN316]

The way you (assuming you're British) say aluminium is precious.

[@OlleLindestad]

Since a lot of people in the comments are asking: mutualism, commensalism and parasitism are all technically types of symbiosis. When the term is used loosely, "symbiosis" tends to refer to mutualism.

[@chikeezebilo6545]

I wonder if resource partitioning is built into or appeared in human genes as a defence mechanism against competitive exclusion. Maybe culture and different tastes?

[@seasquirt22]

i dont think so. having diff tastes is prob due to the dispersion of humans and what they found naturally growing in their area whereas culture is similar but also came from religion

[@EvelynNdenial]

crash course really like their chairs

[@edamschroder]

Nitch and Neesh are both correct pronunciations. No aspect of linguistics is static, by it's nature it is dynamic. Saying that the American or European way of pronouncing Niche is wrong is like saying that a southern accent is an improper way of talking.

[@osmia]

I am soooo loving this Ecology course! Challenge to Crash Course Ecology: Barnacle Benefit to Whale> Yes or No? If Yes, what is the benefit?

[@SuperExodian]

i'd have expected mention of farmer ants in this topic, i mean they're basically ants that do the same that humans do, keeping other animals and 'milking' them for honeydew. or it gets even better with a certain species of ants. (following is copy pasted from wikipedia) An interesting variation in ant-aphid relationships involves lycaenid butterflies and Myrmica ants. For example, Niphanda fusca butterflies lay eggs on plants where ants tend herds of aphids. The eggs hatch as caterpillars which feed on the aphids. The ants do not defend the aphids from the caterpillars but carry the caterpillars to their nest. In the nest, the ants feed the caterpillars, which produce honeydew for the ants. When the caterpillars reach full size, they crawl to the colony entrance and form cocoons. After two weeks, butterflies emerge and take flight.

[@mikesnavy]

ecology should be a required class for all business majors

[@nayeberry]

hank i loved seeing you outside in the real world !!

[@yocampout]

wow. you really made that topic actually interesting and entertaining

[@kperlick123qwerty]

Please realize that you just taught in 11 minuets what took my biology teacher 3 weeks. And that was way more entertaining.

[@LovinLearnin]

This guy is just great and cracks me up!

[@JonathanWinterflood]

Barnacle armor, +1 against piercing attacks, +2 against detection, -1 to speed. Size: 10XL.

[@sammai912]

AP US History Crash Course? That would save my grade. Please John and Hank, I beg of you.

[@destiniedorval5285]

this is very helpful they should put questions like brain pop and have the right answer so you know that your actually understanding

[@samanthalikespianos]

Perfect timing. This stuff is on the exam I'm sitting next week (:

[@robertmanciu3708]

This is wonderfully explained. Thank you!

[@MMLRYY]

Whoa. I could totally picture Hank being a hippie. Nice one, Rowan Gavin.

[@mr.d_88]

Dang he looks good in natural light....

[@Dewkeeper]

The element was first termed Alumium by Humphry Davy in 1808, before he settled into calling it Aluminum by 1812- While the postfix -ium had a precedent in at least six other elements at the time, there were at least platinum, molybdenum and Tantalum as examples for the -um convention The -um suffix is consistent with the spelling of its alumina oxide, as lanthana, magnesia, ceria, and thoria for the oxides of lanthanum magnesium, cerium, and thorium respectively.

[@Yo-yo-bruh]

Loved, "and the other one is kind of like 'whatever' ".

[@Slaybrina]

just in time for biology final!! Thanks Hank!

[@runner1399]

Thank God for this! I have a Biology final today and I literally cannot look at another textbook!

[@vishennaidoo4344]

thank you so much, this sums everything up quite nicely.:) (btw niché is pronounced "neesh" )

[@thehatedcat]

Totally love this videos, thanks for teaching nonscience focused people like me some science!

[@federicadevincenzi2011]

really outstanding

[@samuelshort327]

crash course is absolutely amazing and if you don't think so, you can leave instead of trying to point out every little pronunciation error or little-known tidbit of obscure info that he just happens to not know. screw all the nonbelievers.

[@sumerianguy9898]

FOR CRYING OUT LOUD WE NEED A MATHEMATICS CRASH COURSE

[@MrTesfayesus]

I partially understood, and thanks for the bit I did understand. Now to hunt for some videos to help for the other bit...

[@Pupperooni]

There's a Crash Course: Biology on this. He uses animalia, plantae, fungae, and Protista as the four kingdoms within then eukaryote super kingdom (I forget the correct term). Bacteria and archaebacteria are separate.

[@KK-pf1ye]

My teacher explained fundamental and realized niche's different. So now im confused @_@ (Fundamental niche - the total range of environmental conditions that are suitable for a species existence. Realized niche - the range of environmental conditions that a species actually occupies. )

[@vivid7369]

Thanks bro.

[@obaldius]

I love you, crashcourse ... In a commensalism way...

[@Voyhkah]

When he talks about the four kingdoms, he means the 4 eukaryote kingdoms. He also sometimes talks about the other two domains. The 4 kingdoms are Fungi, Protists, Plants, and Animals.

[@shazaman23]

I love the Table of Contents stuff! Does the stuff in those table of contents somehow link to what you search? Like if I searched R vs K should it bring up the Human Population Growth video?

[@Zovioh]

Another great example of this is Z. Some call it "Zee," while others say "Zed." These two groups get into clashes every once in a while and provide comic relief to outside groups.

[@cmdnoob]

I learn more here then I do in my bio classes in college.

[@martiniuturtlini]

Hank does have a master's degree in environmental studies and is biochemistry major though. He does have some scientific training and the show is written with the help of people who teach ecology and biology.

[@zaw408]

i just learned this in bio class today! :D this was a like a funner neat revision

[@americancheeze1]

Always an enjoyable show.

[@macjsus]

Yeah I would agree that applies definitely for the same language spoken with different accidents in different regions. Like French in France, Canada, and Africa have different accents, or Spanish in Mexico vs Spain. But for words that originate from a different language, like a Chinese or Arabic word or name, I usually try pronounce it the way they would because that is just how I am, and seems more proper to pronounce those in their native language accent.

[@theobrignall4159]

This is brilliant!!!! Thank you soooo much Hank, this really helpful

[@S117MasterMatt]

oohh and quantum computers! you should talk about them, they are sooo cool. Hank you might find them really fascinating.

[@werty1326]

Yay new episode.

[@jeebersjumpincryst]

hee hee! thumbs from me :) I had that one in mind too, but just couldnt get the wording down - but no need - u well and truly took care of it!

[@danxl5]

They are the exception!

[@stephen91396]

I like how if you switch those words, it still works. :3

[@da-hn]

2:38 Czech captions on the picture, yay!

[@ÁnláfBeraslecg]

I'm writing a paper applying concepts of the ecological niche to J.G. Ballard's High-Rise. It's like a wicked combination of John and Hank. English and Science.

[@freddh2]

The thing is the word is originally French, hence the awkward pronunciation. So I guess you can pronounce it the way you like once it's been integrated in your language, but the standard accepted pronunciation would be following French phonolgy, that is with a long "eee" sound to mimic the French "i", followed by a "shh" sound, since the sound "tch" doesn't occur naturally in French pronunciation (except for foreign words like "patch" that were obviously borrowed).

[@Citizen1117]

Nitch IS the standard and proper pronunciation!!!

[@Pupperooni]

Was this the first ecolography? Woo!

[@kmnumdash]

I wanna buy the Warblers book he has! But I can't seem to find it when I search 😭

[@inezgalore]

bless his soul for time stamps omg

[@mathjb94]

Hank, do you base these episodes on Campbell Biology...? They're soooo similar to the summaries I do out of that beautiful, magical, incredible book :P

[@preachingamigo]

He is actually correct, an Ecological Niche is pronounced as either neesh or nitch.

[@mathjb94]

No, parasitism is a different kind of mutualistic relation, because they have a negative effect on their host, probably leading to their death after a while. Hope this helped :)

[@geekgroupie42]

that would be awesome! i'm now going to hope for that too.

[@carinarose8600]

Wish you'd go into Lotka-Volterra in this vid. And Tilmann's model.
