Bopper kurva
From what i remember, it has to do with the noise of flowing water. Bevers find the sound annoying and will cover it until it stops.
I remember a study where they played river noises from a speaker and the bevers covered the speakers with sticks – even in the absence of any water.
I’m not sure if this means that they are annoyed or if they use it as an indicator that there is something to do.
Should be simple enough: check their cortisol levels in the presence and absence of various water stimuli.
Has anybody thought to just ask them?
See, sometimes the best scientist needs to ask the simplest questions no one thought to ask.
Here is your Nobel Prize
Stick to the facts and don’t get too deep into the woods. Good ideas will always float to the surface.
The problem is it’s often hard to see the forest for the trees.
Too busy, those beavers.
You say this like drawing blood from wild beavers is a trivial task!
Super fair point, I’m projecting human emotions onto the beavers & don’t actually know how they feel about the sound of running water lol
It can be both.
Well, dam
“Well dam” - beavers
Can’t you just play the sound of running water and trigger their instinct? I feel like I read that sometime in the last few years.
Actually, I don’t even know that you have to do that much I’ve seen videos of beavers in captivity seemingly trying to build a dam on dry land
I wonder if there’s some kind of near-surface pipes they might hear water running through.
i mean looking at how all animals behave, in the absence of anything resembling their natural habitat they’d probably hear a fan running and feel it’s close enough to running water.
Some fun reading on why https://gsas.harvard.edu/news/dammed-if-they-do edit: https://www.livescience.com/why-beavers-build-dams
It goes into the how but did they explain the why? Maybe I missed it somewhere
Edit: they’re just really particular about the way their water flows
Sorry I had a few tabs open, this ones a little more informative as to why https://www.livescience.com/why-beavers-build-dams
Fascinating read. Thank you.
That awesome! Thanks for the article great read.
“Beavers are 40-to-80-pound [18-to-36 kilogram] smelly bags of meat with really short legs”
So, how does one cross post to another community/instance? I feel as though this could fit in with the beaver community on lemmy(dot)world, but I have absolutely no clue how to cross post.
You should have an option to crosspost it somewhere on the post. Or you could simply copy the direct image link and make a new post using that. Lemmy recognises crossposts by checking if the link is the same. For example if 2 unrelated users make 2 different posts with the same article it will count as a crosspost.
Do they actually dam everything or just build a nest?
The lodge is generally in the middle of the flooded area after they dam it or on the shore in a burrow with the entrance under water deep enough that ice won’t freeze if shut if there’s not enough water. They don’t tend to live in the dam itself. They use all the water to protect themselves.
It should be noted that, aside from petty human concerns like flooded roads and properties, beavers are much better at controlling flooding and generally protecting ecologies than humans.
Saw a thing once, maybe Mythbusters, that showed how beavers are attracted to the sound of running water and want to stop it. In the show, they got the beaver to dam a speaker by playing river/stream noises through it.
Behold wonders of the Beaver Deceiver!
