Bats are cool

Bats are the only true flying mammals. There are over 1,400 species of bats, and they can be found on nearly every part of the planet. Not only are they cute, they are also important...

Studying how bats use echolocation has helped scientists develop navigational aids for the blind. Without bats’ pollination, seed dispersal, and pest control we wouldn’t have bananas, avocados, mangoes, agave, or cacao… that’s right, bats bring us tequila and chocolate!

Found a bat in need of help?

There is no way cacao is pollinated by bats. it's flowers are minuscule and wayyyyy to delicate to be pollinated by probably even a large bee. Afaik, they are gnat pollinated or otherwise human pollinated.

I have two in my yard and there is a 0 percent chance that a bat could ever even accidentally pollinate a cacao.

Here is a link to a video I just made of a cacao flower:

If you look at the wording on the picture - it does not say they pollinate cacao, rather that they disperse seeds for it. I think my title made it confusing, and I should have added seed dispersal...

You will find that bats are very important in cacao production regardless of how you define their contribution.

[–] TropicalDingdong@lemmy.world 0 points 2 years ago (1 children)

I think the point of this sidebar is that these kind of mindvirus ideas get spread, but when you scratch beneath the surface, they are all kissing cousins referencing one another.

This particular version doesn't explicitly state that bats pollinate cacao, but it strongly implies. Dig around some more and other referencing this do explicitly state; yet no where is it provided that all of this is basically based around one study, which was really just a correlation between bats and cacao productivity in one small area. Its an issue in science communication in general which is why this thread started, to peal back the layers of the onion a bit and dig further. You can see below for some images I took after I saw this post of cacao that I am personally growing. I also posted a link to a YT video I took showing the flowers and how its basically impossible for a bat to pollinate them (and several of the mentalfloss type sites citing the one you linked do explicitly state that). But this is how 'wrong explanations' for how things work begin. Factoids aren't facts, but fact-like-objects.

[–] ickplant@lemmy.world 2 points 2 years ago (1 children)

I'll be happy to update the sidebar, I understand the need for accurate communication in science. I also would have thought that Canadian Geographic would be a good source, but apparently not.

[–] TropicalDingdong@lemmy.world 1 points 2 years ago

Well its a good lesson. Thanks for being open minded. Also check out the video to see what a cacao flower looks like.

Afaik, the paper found a 37% increase in yields when birds and bats had access to cacao. However, I think this is likely due to bats and birds eating the predators of cacao midges (tiny gnats that pollinate cacao).

This is the key figure from the paper that shows that:

I'm back: although the top ten search results say bats pollinate cacao, I can find no convincing evidence except that the "chocolate midge" is the only cacao pollinator.

But bats eat midges, is the pollen somehow making it through their tract?

Bat people where are you

[–] TropicalDingdong@lemmy.world -1 points 2 years ago (1 children)

I'll post some cacao flowers when the sun comes up.

bat pollinated flowers are almost always large and tubular. because bats are large, at least relative to insects, and even then, I don't think a bee could successfully pollinate a cacao. suns up in 1hr.

[–] Varyk@sh.itjust.works 0 points 2 years ago (1 children)

I looked them up as soon as I saw your comment and actually saw a midge on the edge of one, so I totally agree.

Just wondering what the kernel of truth all of these listicles are referencing is.

[–] TropicalDingdong@lemmy.world -1 points 2 years ago* (last edited 2 years ago) (1 children)

This is a cacao flower. It's about 5 mm wide (half a centimeter). It has no visible nectaries, and it seems like the pollen are in pollenia attached and guarded by anther shields. Like wise, the stigma has some filimants (maybe infertile anthers?) that also appear to be for blocking self pollination. None of that speaks to bat pollination and unlikely even pollination by European honey bees. This kind of floral arrangement would speak to a specific species that needs to be just the right size to get a pollenia stuck to it, then to be able to move that polenia past the filaments around the stigma on another flower. More akin to an orchid or milkweed style of pollination.

(uploading a video too, but it will be a few minutes)

[–] Varyk@sh.itjust.works 0 points 2 years ago (1 children)

Makes sense, there's no evidence I can find that bats pollinate them either, just broad statements and puff pieces and listicles.

Thanks for posting the pictures though, that'll be interesting for anyone visiting this thread

[–] schmidtster@lemmy.world 12 points 2 years ago (3 children)

Isn’t this a bit of a misnomer? Wouldn’t whatever became the the cacao plant or other plants evolved to be pollinated by some other mechanism if bats didn’t exist?

[–] _stranger_@lemmy.world 15 points 2 years ago (1 children)

Or, there were other plants that went extinct because the animals that pollinated them died out.

[–] ickplant@lemmy.world 6 points 2 years ago

Oh, my... I have finally found the perfect thread to comment this:

Evolution works in mysterious ways.

[–] Knusper@feddit.de 5 points 2 years ago

It's impossible to say. There's certainly no guarantee for a cocoa-like plant to exist, so bats not existing as (initially badly adapted) pollinators could have certainly been their death sentence, depending on how everything else played out for them.

It could have also just resulted in cocoa plants evolving very differently and ultimately not tasting like the cocoa we know today.

[–] TropicalDingdong@lemmy.world 3 points 2 years ago* (last edited 2 years ago)

Bats don't pollinate cacao. it's flowers are tiny and would never survive pollination by a mammal. The headline is misleading.

[–] SCB@lemmy.world 10 points 2 years ago* (last edited 2 years ago)

Or guns! Without bat guano, gunpowder never would have been discovered, and non-guano-related source of saltpeter would likely never have been invented.

Especially relevant if you want to explain why your fantasy world never "inevitably" develops firearms - maybe bats never evolved, or maybe no one ever tried to make life-extending elixirs from bat poop and accidentally discovered bombs, as happened on our world.

Avocado in salmon sushi rolls > avocado toast (though both are delicious). Also just avocado with soy sauce. Basically avocado with salt is amazing, is what I'm getting at.

[–] ickplant@lemmy.world 3 points 2 years ago (1 children)

You got my taste buds going. Yes, I am a very big fan of avocado in salmon sushi... mmmm, sushi. Did you know some bats actually eat fish? Just trying to keep it community-relevant 😅

[–] Drusas@kbin.social 3 points 2 years ago (1 children)

I had no idea. That's really interesting. There's such a broader variety of bats than people realize.

[–] ickplant@lemmy.world 4 points 2 years ago (1 children)

Very broad, here's a short typology:

Seems to be missing the cute, scared baby archetype.

So bats are the reason millennials have no houses?

[–] set_secret@lemmy.world 4 points 2 years ago (1 children)

I'm pretty sure wasps pollinate figs..

[–] ickplant@lemmy.world 4 points 2 years ago (1 children)

It doesn't say they pollinate it - they spread seeds for it since they eat the fruit.

[–] set_secret@lemmy.world 2 points 2 years ago (1 children)

oh yeah fair call, sry my bad.

[–] ickplant@lemmy.world 2 points 2 years ago

No worries, my title totally made it confusing. We ended up having a great discussion about it ITT.

[–] ArugulaZ@kbin.social 4 points 2 years ago (1 children)

Chocolate, tequila, and avocado toast. Now that's a party!

[–] Wrench@lemmy.world 4 points 2 years ago

How did this get so many up votes with a title like that? Bats are not exclusive pollinators for any of those. Obviously.

I'm sure there may be a near exclusive pollination relationship for a bat or two, somewhere. But nothing cultivated by man, for obvious reasons.

[–] totallynotarobot@lemmy.world 3 points 2 years ago (2 children)

What do they have to do with the toast

[–] ickplant@lemmy.world 3 points 2 years ago (1 children)

They pollinate the green gold aka the avocadoes. The toast is merely a vessel for its scrumptiousness.

[–] ramenshaman@lemmy.world 1 points 2 years ago

I eat a lot of avocado and it's almost never on toast. They could have just left toast out of the title and I would have been less confused.

[–] janus2@lemmy.zip 2 points 2 years ago

ah yes the majestic avocado toast flower

[–] Tag365@lemmy.world 2 points 2 years ago (1 children)

Wait, bats pollinate fruits? I had no idea!

[–] ickplant@lemmy.world 2 points 2 years ago (1 children)

They do! Chiropterophily is the official term for pollination of plants by bats. They mostly pollinate at night, and they can carry a lot more pollen and thus spread it farther.

[–] Tag365@lemmy.world 2 points 2 years ago (1 children)

I wonder if there are any other non-insect pollinators out there...

[–] ickplant@lemmy.world 1 points 2 years ago (1 children)

I know that hummingbirds pollinate, so that’s a yes.

[–] Tag365@lemmy.world 1 points 2 years ago (1 children)
[–] ickplant@lemmy.world 1 points 2 years ago

This is actually super cool, I'm glad you asked. Apparently honey possums, lizards, geckos, skinks, and slugs can all pollinate. There are probably more that aren't mentioned here.
