Tress Make Nosies, and Some of Those Sounds Are Cries For Help
Smithsonian ^

Posted on 04/16/2013 3:57:53 PM PDT by Dysart

It’s easy to dismiss trees as inanimate features of the landscape, but these living, breathing organisms aren’t as stoic as they appear. Trees, it turns out, make all kinds of noises as they grow and respond to their environment. Happy, regularly growing trees sound different from drought stressed trees. Now, a team of researchers from Grenoble University in France is trying to pick out these cries for help amidst all the normal tree white noise in order to provide better, more targeted aid to trees suffering from drought, according to National Geographic.

In the case of drought, trees undergoing stress form tiny bubbles inside their trunks, NatGeo explains, which causes a unique ultrasonic noise.

Imagine using a straw to slurp the last few drops from the bottom of your glass: You have to increase the pressure even more. In drought-stricken trees, this increased pressure can cause the water column to break, allowing dissolved air to form bubbles that block water flow.

These breaks are called cavitations, and they can eventually lead to a tree’s demise, so researchers and managers are interested in identifying warning signs that indicate that a tree needs emergency watering.

The sound is actually the heralding of yet another crisis that somehow requires taking food from my family to solve.

“Tress Make Nosies”? Is that supposed to be a dirty joke?

I hope the Admin Mods do not change or correct the title.

Because this thread will go down in history with the 'al baby' "stuned beeber" thread from back in 2004.

Oh, please. All liberal crap like this originated in France, and I see they're still cranking it out. Stress a rock and it makes noise, too. But it's not a cry for help... Sheesh.

I like the screams they make when I fell them cut them up. Split them and chuck the pieces into my airtight stove. Then after I close the airtight door the screams subside and all I hear is pops and crackles. ; )~

Just as the 3000 year old mummy looked better than Hillary, so does that tree.

Yep, it’s botched something fierce, and no, I’m not intoxicated. Just inexplicable. I’m thinking sleep deprivation, though.
