SciShow Talk Show: Biocrust with Rebecca Durham

[@LachlanJP81]

Man, I love seeing people so passionate about such specific things like this :P

[@KaiCalimatinus]

This was really interesting, as always. I took a moment wondering the scale of enthusiasm about her field, and then with admiration realised all the facets of knowledge studying into the lichen and biocrust could fit into. Puzzle was adorbs, like all of the Animal Wonders guests. I love sneks, they're so interesting and majestic, their scales, on constrictors mostly, are so smooth and sleek like that. At first glance reptiles seem quite alien but when you learn some behaviours its easy to start seeing how emotive they really are.

[@Qermaq]

My only complaint is this seems to presuppose I know what a Biocrust is. I was lost most of the interview.

[@evang-f2845]

yeah.. this bothered me, no one explained it.. at least I don't think so?

[@ssppeellll]

At 50 seconds in he says, "Biocrust--these living soil matrix things." How much clearer could he make it? ;-)

[@VeNoM0619]

I was terrified at 7:17, lycans live everywhere, even underwater. Werewolves are no joke...

[@Hawtsaus]

5:50

[@Nurr0]

Same thought here. I still don't feel like I know what the biocrusts do beyond being important... But I wish I knew why.

[@fatsquirrel75]

Rebecca needs her own channel. I didn't even know I cared about moss until now. Much more entertaining that I thought it'd be.

[@Luchoedge]

3 minutes in. I WANNA SEE THE THING THAT YOU'RE TALKING ABOUT!!! SHOW IT!!

[@gildedbear5355]

same here

[@EvelynDayless]

NO

[@nekozukiiiii]

I know right? my eyes are craning to see what it looks like @.@ :/

[@Manibe37]

I couldn't wait for them and googled it haha

[@jamestrotman3238]

with talkshow not in the title, i thought it was an extra long scishow

[@Pinkkpandamanda]

same

[@Boycicle]

+mrsaj789 Same same

[@LordDragox412]

And I was here scared they didn't bring Jessi for this episode of talkshow. I guess... They just didn't want to get people too Puzzled... #Kappa

[@amarallis420]

Thank god I was not the only one confused for a moment.

[@mariakafka7686]

Same Then I got sad

[@Ravinian]

The scope of human interest is amazing.

[@VEE727]

Is it just me or time flies when Jesse arrives

[@oldcowbb]

best part of every talk show

[@TheGrandMasterFunk]

Really loved it, incredibly fascinating, especially the drought bit around 10:30

[@skybluskyblueify]

Not only did you talk about poikilohydric organisms but also an poikilothermic organism. It was a poikilo day. Good to see these videos are still up and available in 2024.

[@davidbuschhorn6539]

Mosses are the most amazing things to me! At Eastern Washington University, I was introduced to their life cycle and it blew my mind! All these years later, they still fascinate me :-)

[@rrio695]

Thank you for another very informative program. I'm now interested in the subject and will spend a couple of days looking into it. Take Care Hank!

[@MaxxEastick]

Awesome interview Hank, you need to do a Sci Show on BioCrust now, when you know more on what it is, it is really interesting. Here in Australia, I have seen Lichen growing on our roads with no problems (also grows on my iron roof), and seen some grow on tiled roofs under television antennas!, not sure why under antennas, but interesting (It may not be Lichen though!). My Dad (formally an organic farmer) used to say, the sign of Lichen meant life was returning to poisoned land. Where herbacides had killed everything, Lichen was the first to move in, followed by Moss, then "other".

[@oathblade]

All your guests are awesome - Rebecca Durham especially so. Have her back with a water bottle :)

[@macybautista1301]

I wanna see that too!

[@wayinlove]

the animal lady is really sweet with a lot of cool info

[@Kalleosini]

If you like her, I suggest checking out her youtube channel for even more cool info and a lot of different and awesome animals.

[@wayinlove]

Ebon Hawk I did, it's pretty cool and I watched a few of her previous videos here too

[@Wingedshadowwolf]

Due to the soil around my yard being difficult to work with I started container gardening on my porch. For potting soil I mixed my own out of bagged soil, peat moss, steer manure and vermiculite. I bought it all at a big box hardware store and mixed it up as I needed it. When left undisturbed the manure grew algae, moss and lichens like crazy! There many different types. They even grew in the plant pots that were left over the winter. I almost wanted to make planters or terrariums just for them.

[@MatanuskaHIGH]

crappy soil..dont buy shit from box stores..

[@Wingedshadowwolf]

+matanuska high Yeah, the lichens in the manure was kinda cool. The cheaper pre-made garden soils seemed to be fortified with wood splinters. This year I finally had enough money to drop the cash for some landscaping. I cleared a space for raised beds and bought a dump truck load of top soil. It will still need amendments, but it looks way better.

[@duck8dodgers]

One of my first jobs was to teach hiking and backpacking at a summer camp in Arizona, and this was before there were signs everywhere warning about the macrobiotic crusts. I made sure everyone who took my class knew what they were and why they were important for the desert.

[@crystalcoolidge6297]

5:50, I see trumpet lichens! I love those! They grow pretty much everywhere around Anchorage.

[@adriangribincea2656]

print ("I love PYTHON!")

[@oldcowbb]

haha

[@rpsdata]

Great Show! I love how Rebecca's eyes lit up when she first saw the python. Snakes get way too much hate for how derpy most of them truly are.

[@Max-vb6le]

one almost killed my sister. nah.

[@Max-vb6le]

she was in the hospital almost dead with little blood pressure after venomous expose.

[@NathanHart]

How long do we have to wait to see a zoom in on the biocrust that's in focus?

[@threadthathasnoend1212]

They really need to name it: 'The Rolling Stone Moss Gathering'

[@JimFortune]

So you could never have the Rolling Stones play at a moss gathering, right?

[@Voyhkah]

YOU TOOK MINE

[@JimFortune]

***** Hehehe

[@gryphonshire]

My elder son had two ball pythons many years ago. Beautiful snakes, he named them Hellfire & Brimstone in spite of the fact they were both amazingly tolerant of humans. I used to "wear" Brimstone around my neck (he liked the warmth.) He never tried to squeeze me, but liked keeping his head up to look around as I walked with him. :-)

[@synkyg]

Next time start by telling us what bio crust is please

[@synkyg]

lmao

[@sumdumbmick]

I like how in all the names 'crust' is constant, but the part that specifies the type of life it is, which is pretty highly variable, kept changing until it finally landed on something appropriately generic.

[@Cineenvenordquist]

Yeah. It's a new discipline of pioneering mountain randos, without expecting people, mining entities or Monster Hunter loadouts. And not fresh powder either...

[@thedominosguy3015]

Hi Sci Show!

[@SciShow]

Hi!

[@Mr_Scrooge]

+SciShow no way

[@camelCaseFTW]

Moss Gathering?!?! LMAO that is awesome!

[@Cadwaladr]

The stuff about mosses and lichens reminded me of all the moss and lichen scientists I met in Tierra del Fuego. There was this one Spanish guy who was giving a talk about the mosses and lichens and we're just in a forest but I was listening to him and it was the first time I'd ever listened to someone speak Spanish where I understood every word he said. His name was Professor Leopoldo Sancho from the Complutense University of Madrid.

[@fegolem]

I recently came upon a Copperhead that I think had shed it's skin not long before. The patterns and color borders and gradients were beautiful. I took some pics.

[@MrKarim992]

share please!

[@celtgunn9775]

Royal Pythons are so awesome. I've got 8. 😊 Love them!

[@mongomoonbladder8023]

Hank Green for President !

[@Beringer90]

I loved her! She is such a sweet person

[@craigjr.8216]

"I loved her". So you don't love her now?

[@craigjr.8216]

I'm probably being harsh

[@Beringer90]

Baby Craigalicous Yup, english isn't my main language, but thanks for pointing that out!

[@RandomDod]

That sentence made perfect sense in the context, the other guy is being pointlessly pedantic.

[@PrinceRules64]

Assuming that you finished watching the video before commenting then you're describing an experience in the past and there's nothing wrong with it. You didn't say "I had loved her" so technically there's nothing to say you don't love her now. Grammatically it's flawless.

[@biggathangigalol]

"Here's puzzle, do you know what she is?" Me: "basically a slippery legless spider, i.e. A massive nope"

[@JustThomas1]

Very interesting episode (?). I learned quite a bit from this episode :) .

[@PinkChucky15]

Awesome video. Great topic and great animal :-)

[@MuadDib1402]

I don't know how Rebecca feels about being called an animal, but she was rather nice.

[@PinkChucky15]

Ha ha. Yep, she was pretty cool.

[@gameoverwehaveeverypixelco1258]

a channel made a terrarium recently with rocks and soil and mushrooms and moss etc, looks epic in a glass jar as a display.

[@Thepackardsonic]

And here I thought that biocrust was what you got when the kids came home from playing in the mud. LOL

[@michaelgrossman5059]

5 mins in still no idea what biocrust is! lol I'll have patience since I love you SciShow

[@dustman96]

Rebecca Durham, you're enthusiasm and knowledge of this makes you so incredibly attractive.

[@BlackJohnnyCage]

I thought Lycans were from Underworld lol!

[@Pinkkpandamanda]

same lol🐺

[@Komalaso]

It's lichen not lycan?

[@Pinkkpandamanda]

+Komalaso sarcasm?

[@gamesman0118]

Beware the Lycan Lichen!

[@dudeimadolphin4318]

amazing content

[@nathantron]

I wish this video had some more visuals so we could understand a bit more.

[@grndragon2443]

so is the lichen that is in western Oregon trees killing the trees or are the trees dying giving the lichen something to grow on?

[@ratatataraxia]

Only when they bring out the animal did I realize this was sci show talk show. I thought it was just a really long video, I should have recognized the set.

[@jacobjamar]

She'll be really fun to hang out with! I love mycology!

[@jacobjamar]

He's very awkward in a conversation view point!! Never would have expected!

[@Christuserloeser]

5:50 FINALLY!!! so that is what they're talking about.

[@theswedishchicken5963]

What are white holes? PLEASE make a video about it :)

[@kevinpham8693]

If you know what he means ;)

[@mustardsfire22]

Check SciShow Space.

[@TheSilverDragonX]

SciShow Space is the place for that.

[@JanPospisilArt]

The Cat: So, what is it? Kryten: I've never seen one before - no one has - but I'm guessing it's a white hole. Rimmer: A *white* hole? Kryten: Every action has an equal and opposite reaction. A black hole sucks time and matter out of the Universe; a white hole returns it. Lister: So, that thing's spewing time... Lister: [donning his fur-lined hat] ... back into the Universe? Kryten: Precisely. That's why we're experiencing these curious time phenomena on board. The Cat: So, what is it? Kryten: I've never seen one before - no one has - but I'm guessing it's a white hole. Rimmer: A *white* hole? Kryten: Every action has an equal and opposite reaction. A black hole sucks time and matter out of the Universe; a white hole returns it. Lister: [minus the hat] So, that thing's spewing time... Lister: [donning his fur-lined hat, again] ... back into the Universe? Kryten: Precisely. That's why we're experiencing these curious time phenomena on board. Lister: What time phenomena? Kryten: Like just then, when time repeated itself. The Cat: So, what is it? [Kryten, Rimmer, and Lister stare at Cat] The Cat: Only joking.

[@ErgoCogita]

White holes are very probably just an artifact of our models of spacetime but still interesting to contemplate.

[@strangecreature9125]

Where did Bats come from and how old are they?

[@SpankytheTswana]

Hi everyone. i'm new to this channel. I wanna know if bowed legs are stronger then 'normal/linear' legs. I have bowed legs (normal bowed, not rickets bowed) and I'm intrigued to as to whether if I jump for example, if shock absorbed better in these legs than in that of another and if the legs are more likely or less likely to break under stress because of the bend... thanks

[@clayw1996]

My socks are filled with biocrust

[@TheGrandMasterFunk]

how can I incorporate this into my garden? Some of my potted plants have some fuzzy moss ontop, now I want to try and identify it XD

[@SpamminAintEasy]

Most species of moss are pretty hard to identify unless you're an expert. You can get as close as genus or family pretty easily but knowing species will likely require either a microscope, genome, testing or both. I definitely encourage trying though, might find some good research papers on moss species that grow specifically with the species of plants you have potted!

[@BrunoHenrique-gi1wd]

"In crust we trust" is fucking fantastic

[@theoryaction]

DON'T STEP ON THE CRYPTOBIOTIC SOIL! -every sign in Canyonlands

[@idontwantachannelimjustcom7745]

in hardiness zone 6a is there any species that can colonize my yard if I rip up the grass? I hate mowing.

[@JohnSmith-td7hd]

I still don't understand how snakes move. I need to see the muscles and scales moving. Could you do a SciShow episode dedicated to showing that?

[@brentv1150]

Anyone else having the grid illusion from Hank's shirt? Dots appear at white cross sections of the plaid.

[@VeracityTrigger]

'Endangered dirt, that's a new one'

[@Tfin]

0:27 It's a werewolf, Hank. She studies plants and werewolves.

[@jasonmcburney2370]

need more "Hankisms" and the effects of the green screen. Make it cool for the layman.

[@HappyHusbandnWife]

I get bored and still dont know what biocrust is at 3:00

[@MsHuricana]

Someone's gotta roll up some of that crust, it ought let out nice vapes if you what i'm saying. :D

[@Adi-pw1ed]

I moss say I'm lichen this! 😁

[@francescamele8077]

I would have liked Jessi to tell us about having one of these small(ish) snakes as a pet, if she thinks it's fine or not.

[@paulrichardspencer]

fungi, which was discovered in Europe is said fun-gee (like the rendered butter)

[@sierragoldrush7479]

I remember being stumped by cryptogammic soil back in the day. When you had to leave the house to learn something. Kudos.

[@mantasreika]

very interesting :)

[@mitchellh2479]

I have a question: Why is it that in America your chicken eggshells are usually white whereas where I live (Australia) our eggshells are a pale brown?

[@MatanuskaHIGH]

the breed of chicken we sell commercially..farmers grow all colored eggs..but commercial farms grow the white ones. you can buy brown eggs at the store also. but most people buy the white ones..

[@mitchellh2479]

oh thank you

[@wiertara1337]

She has perfect voice.

[@Sillydanceboi]

You should do an episode as to why some people can sing and why others are tone deaf and if you can really teach someone who can't sing how to sing or are signing teachers just scamming you.

[@TheSpiralAim]

Ball Python, the most vicious animal in the animal kingdom!

[@MicroBlogganism]

If you want to keep clades monophyletic, and most biologist do, technically speaking, snakes are lizards

[@d3g3n3r4t3]

2 Girls, One Snake! They discuss serpent muscle structure!

[@mrcat-nu1jb]

so I was exploring my aunt/uncle land and I found this bottle that was laying mouth up so it got water dirt and moss in it so I brought it home and some times I give it water 😼

[@Ginger_Chin]

So you water a bottle? Cool story bro

[@mrcat-nu1jb]

+Triggs no i found a glass bottle that contains moss and I some times give it water so it continus to live 😺

[@dm_nimbus]

I love the name Puzzle

[@TheEvilVargon]

"Funji"

[@mollye]

"Fungai"

[@piemaster3181]

*"funji is"

[@biggathangigalol]

"Aljee" not algae ;)

[@DanThePropMan]

+He Who Divided By Zero *"funjare"

[@gilliansafavizadeh226]

What happens when you have an itch?

[@booksandcat]

It seemed like Hank was out of it during the episode; he was quieter than usual and near the beginning you could see him stifle a yawn. I'm sure he's just exhausted from the tour, but get some rest Hank!!

[@arugula_fan]

Awesome

[@mirzamay]

Snakes are sooo creepy. But biocrust is fascinating.

[@gamesman0118]

Lichen could be used as a Terra-forming step.

[@wallcus3077]

It's a C#! No wait, it's a Python!

[@Nick-wv4kg]

Can you make a video about why we tan?

[@convex242]

I miss having a snake but a California King wasn't a good species for me to own. At all. Still, I do feel bad I couldn't keep her sometimes.

[@Tanjman_]

Lichen is pretty much all that Woodland Caribou eat

[@anna46792]

i feel like i would be able to enjoy this better is there was some type of explanation in the beginning. i know she tried and this is what she has specialized in. so to her that was simplified. but it still felt really lost and unable to fallow.

[@drunkenroundtable]

It would have been really nice if at some point in this video you actually explained what the hell biocrust is. I'm from Florida (the complete opposite of an arid climate), and I've never heard of the stuff.

[@JaceLeeRogers]

Is it just me or does the wind blow less at night?

[@michaelgrossman5059]

Im sorry SciShow I watched the whole thing and I still have no idea what it is. I know it has moss an lichens. but like is that it? how big is it where those small samples? how does is look dofferent than just dirt? is it under the dirt or right on top? It was not outrightly defined once. she kept saying it was important, why? does it help with fertilization/decomposition? whats its place in the ecosystem?

[@MAXgiz2011]

what's a funji

[@aarcaneorg]

she took a lichen to it! ha ha!

[@Fotbaladdicted]

Why is water so hard to drink sometimes and sometimes you drink 1L with no problem?

[@davidbuschhorn6539]

Little known fact... Rebecca is also getting a creative writing MFA :-)

[@pattikillem666]

I love her.

[@stvie3]

3.5M subscribers & your visuals are on a phone?! #phoneitinwhydoncha

[@thanrose]

"I collect molds spores and fungi."

[@EebstertheGreat]

Weird that Rebecca corrects him on "algae." Aren't there lots of lichen-forming algae?

[@ravinravi554]

Hey look it's Elena fisher from uncharted

[@TheBCBuddy]

I'm lichen this video....

[@leken2619]

Maybe you should mention at the beginning of the video what Biocrusts are supposed to be.

[@maxmusterman3371]

they really should hav. especially because english isnt my mithers tongue so i had no idea what it was
