Tf are the other trees going to do with this information? Run away?

[–] Beacon@fedia.io 49 points 2 days ago (2 children)

In response some plants can do things like release toxins or foul tasting chemicals to kill/deter predators

[–] marble@sh.itjust.works 16 points 2 days ago (2 children)

That's pretty cool, thanks. If you need me I'll be reading about this on Wikipedia now...

[–] Beacon@fedia.io 27 points 2 days ago

I just did some quick reading and i found a really cool one! One defense mechanism response is that the plant can release chemicals that attracts the predators of the insect that's eating the plant!

I once knew a marble... sadly they're lost to us now. They were last seen on the Wikipedia page for bill hooks three months ago.

We mourn the loss of their loved ones.

Group farting deterrent.

[–] ricecake@sh.itjust.works 9 points 2 days ago

This tree looks to increase the toxicity of its leaves to deter giraffe.

[–] BastingChemina@slrpnk.net 5 points 2 days ago

They can send a chemical that will make their leaves taste bad.

Wait until you get to mycelium networks, that's a life-long rabbit hole

The secret glue that holds all life together

When I was at the psychiatrist's to see about getting diagnosed I was asked how it was affecting my everyday life and somehow I ended up talking about the migration patterns of Romanian shepherds

[–] Death_Equity@lemmy.world 22 points 2 days ago (2 children)

I can see how you got there. Not sure if that is a good thing or a bad thing but what I do know is that bees communicate by dancing.

I am so glad other people with ADHD can see the insight into trains of thought. Which makes me wonder why we don't have more vehicles run on Diesel generated Electric power.

[–] grue@lemmy.world 6 points 2 days ago (1 children)

Which makes me wonder why we don’t have more vehicles run on Diesel generated Electric power.

I've wondered that too (especially as the owner of a diesel car). My best guess is that hybrid drivetrains come at a price premium compared to plain gasoline engines and Diesels also come at a price premium compared to plain gasoline engines, so trying to put both on the same car would incur a double price premium and not enough people would want to pay it.

[–] Death_Equity@lemmy.world 3 points 2 days ago

It's just a diesel range extender, they wouldn't have to use all that big of an engine. Just like on locomotives, the diesel is just is a generator to power electric motors. No integration into the drive line, the diesel has a generator on it that feeds the batteries.

One guy put a diesel engine in a Tesla as a range extender and it had a range of over 2,500 miles. It got like a 400mpg.

[–] Maggoty@lemmy.world 2 points 2 days ago (1 children)

A second engine costs more, weighs more, needs more support, and makes everything harder to repair.

Basically, internal combustion to the wheels is cheaper for the car builders and good enough.

[–] Death_Equity@lemmy.world 4 points 2 days ago (1 children)

Diesel electric, not diesel hybrid.

Diesel generates power that charges the batteries. It would be more expensive than a normal ice car, but it would have thousands of miles of range and get 8-10x the range per gallon.

[–] Maggoty@lemmy.world 1 points 2 days ago

Afaik the only difference at the general level is whether the IC engine connects directly to the wheels or not. A hybrid can run on either engine. A diesel electric uses an IC engine to create electricity for an electric engine. So you still need at least two engines, it's just wildly more efficient. And quite a bit more expensive to produce.

[–] NocturnalMorning@lemmy.world 11 points 2 days ago (1 children)

Were you also at the psychiatrists office OP was at? Seems to be a trend... unrelated, but i found out the other day that squirrels are becoming carnivorous.

[–] Death_Equity@lemmy.world 11 points 2 days ago (2 children)

I doubt that the care provider is the commonality. Centipedes don't have sex, the male drops a semen bag on the ground and the female finds it and uses it to reproduce.

[–] Infynis@midwest.social 7 points 2 days ago* (last edited 2 days ago) (1 children)

There must be something else at play. It could be that, unlike other cephalopods that swim, like you would expect, the nautilus propells itself through the ocean by expelling high pressure jets of water

[–] Death_Equity@lemmy.world 5 points 2 days ago

I have no idea what it could be. I see the possibility that the great pyramid has large voids that are filled with sand and debris caused by stone cutting is a valid hypothesis given the sand found when the French team bored into part of the pyramid in the 80s. Using sand and rubble to fill in voids would expedite the construction process so that the 20-30 year construction make sense. That also would be a progression of the attempt to stack blocks on a mound of sand and rubble to build a pyramid, which failed in the fifth dynastic attempts.

Stop it you asshole, I'm willing to go down that rabbit hole. This is like pointing a loaded gun at my face and asking me to ignore it.

Edit: Did you know cats are the only mammal who don't taste sweetness! Must be related...

[–] someacnt@sh.itjust.works 9 points 2 days ago (1 children)

How do you guys retain memory of what you looked into for long enough that you can post about it?

I just cannot infodump like this, I wish I could.

[–] Earflap@reddthat.com 6 points 1 day ago (1 children)

The less useful the information the more I will remember it.

Ethylene gas also makes apples go bad. Not sure what I'm going to do with that info, but I know it.

[–] JoeBigelow@lemmy.ca 7 points 1 day ago

And that's why "One bad apple spoils the bunch."

[–] DarkCloud@lemmy.world 21 points 2 days ago

*Acacia trees.

[–] feedum_sneedson@lemmy.world 2 points 1 day ago

damn that really ripens my bananas

brb gonna go into the woods with an ethylene tank and do some trolling

[–] skeezix@lemmy.world 17 points 2 days ago (1 children)

Sometimes I emit clouds of methane gas just to fuck with people.

[–] Imgonnatrythis@sh.itjust.works 6 points 2 days ago (1 children)

Sometimes I emit clouds of methane because God dammit, I'm not just going to cut ice cream out of my life!

[–] MelodiousFunk@slrpnk.net 3 points 2 days ago

I'm in this comment and it hurts real bad.

[–] Zink@programming.dev 11 points 2 days ago (1 children)

Ok, this is sending me off into a Skies of Arcadia rabbit hole. Who is coming with me?

(Note to self: do not dig out the Dreamcast when I get home tonight, because I definitely know where the SoA disc is)

[–] Qwazpoi@lemmy.world 4 points 2 days ago* (last edited 2 days ago) (2 children)

I honestly like the added content of the GameCube version. It's got some bounty hunting type missions against pirates and the power ups to cupil are now found hidden through the game world instead of grinding the save card game on Dreamcast

[–] Zink@programming.dev 3 points 2 days ago

That sounds nice! If I ever really get it in my head to replay it, maybe I’ll have to hunt down that version.

[–] marzhall@lemmy.world 2 points 2 days ago

Of all the games to remake, boy would I love the Skies of Arcadia remake of the GameCube version. ;_;

[–] thenextguy@lemmy.world 6 points 2 days ago

TF is an Arcadia tree?

*Acacia

[–] ryedaft@sh.itjust.works 4 points 2 days ago (2 children)

But ethylene is the ripening signal molecule, right? Why would trees be warning other trees to ripen their fruit?

[–] ricecake@sh.itjust.works 3 points 2 days ago (1 children)

I looked it up, and it also increases the tannin levels in the leaves. So if something is eating the tree, it and other nearby trees change their leaves to become more toxic to what usually eats them.

I'm guessing this leaves them generally non-toxic which helps keep critters they don't mind around.

[–] TheFogan@programming.dev 2 points 2 days ago (1 children)

Aahh that makes more sense... I was more wondering less on how trees can warn eachother, but how much is there that they can do something about.

I was just imagining... "HEY THERE'S A FOREST FIRE COMING"... then a response... welp that sucks.

[–] ricecake@sh.itjust.works 2 points 2 days ago

The trees just slowly sway, their woody groans slowly creaking out "wwwwweeeeeellllllll sssssshhhhhhhhhhiiiiiiiiiiiiiiiiiiiitttttttttttt" as the fire engulfs the savannah.

[–] Buddahriffic@lemmy.world 2 points 2 days ago* (last edited 2 days ago)

Makes sense. If animals are about to start eating, they'll want the fruit to be ready. Obviously the seeds need to be ready, but also the flavour of the fruits themselves so animals don't ignore them and they all end up rotting directly below their parent.

Or, from another angle, one tree that doesn't want animals eating it emits chemical that causes fruit of other trees to be more attractive so animals are less likely to waste time eating the comparatively less nutritious leaves or bark.

And adding a layer to that, even if the animals that like to eat its bark/leaves aren't interested in the fruit, if other animals are attracted to the fruit, it can attract more predators that might be happy to eat animals looking for bark/leaves as well as those looking for fruit. And both predators and prey might also be directly attracted to the original chemical the tree released.

Or it might just be a coincidence. Actually, even if it is functional in those ways or others, it's still a coincidence because that's how evolution works, it just stuck around either because it works or because it's tied to some other trait that does with and doesn't cost enough to be a net negative.

Note: this is all speculation, not based on any specific knowledge about this tree or ecosystem.

I love those.

That's how I learnt QCD before High School
