WTF Fun Fact 13429 – Crown Shyness in Trees

Have you ever seen a tree get nervous? Certainly not, but crown shyness in trees is about to give you a whole new perspective.

Imagine wandering through a dense forest, the quiet whispers of leaves your only company. You gaze upward, finding yourself under a vast, living canopy. Now, observe the leaves’ formation. Notice how each leaf reaches out for its share of sunlight, yet mysteriously avoids overlapping with its neighbor. This intriguing behavior is known as crown shyness.

Crown shyness is a botanical phenomenon where trees of the same species (and sometimes, different species) avoid touching one another. The resulting gaps in the canopy form a stark, jigsaw-like pattern against the sky—a natural artwork of lines and spaces, fascinating and beautiful.

What causes crowd shyness in trees?

The exact cause of crown shyness remains a subject of debate among scientists. Some theories propose that it’s a mechanism to prevent the spread of harmful insects or diseases. Others suggest it’s due to the trees’ sensitivity to physical contact. When branches collide due to wind, they could sustain damage, leading to a phenomenon known as ‘branch abrasion.’ Over time, the trees might “learn” to avoid contact, hence the “shyness.”

But whatever the cause, the consequences of crown shyness on forest ecosystems are tangible. The patterns it creates reduce competition for sunlight, enabling all trees to flourish. Moreover, the resulting gaps in the canopy permit more rainfall to reach the forest floor, benefitting the undergrowth.

Even though we attribute the term “shyness” to this phenomenon, the reality is anything but timid. It’s a fierce competition for survival and a demonstration of cooperative living in the wild. It’s a reminder that trees, though stationary and silent, engage in complex interactions with each other.

The more we know the less we understand

By observing and understanding these unique patterns, we gain insights into the interconnectedness of nature. We comprehend how trees, despite being rooted to the spot, communicate and interact with their environment in ways beyond our understanding.

In our fast-paced world, a moment spent contemplating the “shyness” of the trees can instill a deeper respect for the complexity and subtlety of nature. As we walk under the forest’s green canopy, we’re participating in a delicate dance that’s been choreographed over millennia. A dance where each participant knows their place and respects the other, a dance of survival, adaptation, and above all, cooperation.

So, the next time you wander into a forest, look up. Witness the marvel of crown shyness. You’re not merely observing a scientific phenomenon; you’re peering into an intricate world that continues to inspire, educate, and mesmerize us.

WTF Fun Fact 13081 – Dogs Fake Sneeze

Did you know that dogs fake sneeze? We know our fluffy buddies can manipulate their environment to get more attention, but fake sneezing actually has a few different uses that we found interesting.

Why do dogs fake sneeze?

According to the American Kennel Club (cited below), dogs will fake a sneeze for play and communication purposes.

“Many dogs like to sneeze when they play with other dogs or humans. This ‘play sneezing’ is normal and something dogs use to show that they are excited and having a good time. Dogs will also use play sneezing to show that their behavior is only playful.”

When dogs play sneeze, they tend to curl their lips and create a wrinkle in their nose. These sneeze sound more like a short “snort” than a sneeze, since the air comes from the nose and not the lungs.

Attention-getters

Your pup is watching you closely for signs of what will make you more empathetic and playful.

According to the AKC, “When a dog fake sneezes, they tend to watch you as they sneeze to make sure they’ve got your attention. They may even move closer and sneeze on or near you so you can’t ignore them.”

And dogs will even sneeze to communicate with one another. Sometimes, they’ll use it as a calming signal to let those around them know things are getting out of hand.

Pay attention to dog sneezes

Of course, dogs can sneeze due to illness and allergies as well. So it’s important not to assume your dog is sneezing just because it wants to play. And dogs with compressed nasal passages, like pugs, will sneeze more often simply because of their physiology. This may require attention if it starts to happen more often since it can be indicative of breathing issues. — WTF fun facts

WTF Fun Fact 12822 – How Do Lobsters Communicate?

Apparently, thousands of people look up “how to lobsters communicate” – and we’re guessing it’s because they’ve heard the truth and it’s hard to believe.

When we heard that lobsters communicate with their bladders and that they can make things known to other lobsters by urinating at them, we thought it was a grossly creative form of expression. But it gets even better.

While it might not be the most exact description of what’s happening, no less an institution than the New England Aquarium has informed lobster learners that the creatures actually “pee out of their faces.”

Say what?

Ok, so let’s break this down a bit. First of all, lobsters use scent to communicate (as do humans, to be fair). You’ve heard of pheromones, right? The scented hormone we secrete?

Because this factoid ran rampant around the internet with such gusto, Snopes to it upon themselves to get the details (gotta love those professional fact-checkers!). They describe the scented face-peeing this way:

“Found within a lobster’s pee are a fair number of pheromones, which they disperse through their nephropore rosette glands. The bladder of a lobster is located under its brain, and the rosette glands are connected to the urinary tract.”

Ok, so the key here seems to be the anatomy – the bladder is right under their brain. There’s only so much room in a lobster, and those of us who have eaten them should probably be grateful that we don’t have to pick their bladders out of their tails.

As for the urine stream comes out of their face, Snopes explains further:

“Once these pheromones are produced, they are introduced into the urine stream. In the case of the American lobster, scientific name Homarus americanus, this pheromone-rich pee is released from nephropores at the base of the lobster’s large antennae and then injected into its gill current. According to the NEAQ, it has been determined that this urine stream can reach a length of seven times the lobster’s body.”

Wait, so how do lobsters communicate this way?

You probably still have some questions. Like, what’s a gill current? Well, according to The American Lobster:

“Water passes up through openings between the lobster’s legs, over the gills, and up towards the head.  Every few minutes this current of water is reversed the other way so that debris can be flushed out of the chambers. An important part of this “gill current” is that when it is flowing forward towards the head, it can project urine forward. It is thought that the urine of the lobster contains important information about the sex of the lobster and its physiological state.”

Now that we know how lobsters pee out of their faces, we still need to know how and why it works this way. So, back to Snopes (which is cited below and which also has further reading at the bottom of the page for all your legit lobster urine research needs).

When male lobsters want to attract a mate, the females tend to come to him. But he needs to be in a defensive position. As Snopes says: “Their claws are located at the front, which enables the lobster to back into a shelter and face outward toward the entrance, setting up a first line of defense — and attracting a mate.”

Territorial lobster communication

Snopes also cites the conservation organization Oceana, which reports that a male lobster tends to dominate one piece of territory and females wait outside the den to mate with him. To let him know they’re out there, they pee in his direction out of the nozzles on their face.

Hey, who are we to judge?

Of course, the urine contains the pheromones that signal she’s ready to reproduce. So – and here’s another fun fact – she takes off her exoskeleton (basically stripping naked) once she gets into his den to mate. We are seriously not making this up.

Other lobster communication-by-urine tactics

Ok, so there’s one mating ritual out of the way. But females aren’t the only ones who urinate out of their faces to send a message. When males fight, the winner will do the same to signal to any nearby females that he’s the winner and ready to pass on his superior genes to any females nearby. “It’s thought that the winner of a match will also contain more serotonin and happy hormones, making him even more attractive to a would-be match.”

Snopes caps us off with yet another fun fact:

“How does a female return the favor? By peeing in his face, of course. Pheromones released in a female’s urine are thought to reduce the aggression of an embattled male and he’ll often allow the female to enter his burrow, where she might stay for up to two weeks. While the two shack up, the cohabitating female will also be urinating to ward off other ladies in the area — until it’s their turn.”

WTF Fun Fact 12664 – Mushrooms Talk To One Another

A study published in the Royal Society Open Science journal suggests that mushrooms are pretty chatty. In fact, the electrical signals fungi emit toward one another when they encounter food or danger bear a striking resemblance to human speech, at least in terms of the patterns they use.

Andrew Adamatzky of the Unconventional Computing Laboratory at the University of the West of England noticed that fungi electrical signals spiked in certain situations.

Now, you can’t hear mushrooms speak, of course. Many mushrooms grow as part of a network with tiny roots and filaments connecting them underground, called hyphae – and that’s where the signals are passed.

Adamatzky admits that his experiment is a far cry from finding a secret “mushroom language,” but making the comparison allows us to understand the possible purpose of these electrical signals. In the end, they may mean nothing, but the fact that we can distinguish patterns of electrical activity in certain situations would suggest something interesting is going on.

The article reminds us:

“This is indeed quite a primitive classification akin to interpreting binary words only by sums of their bits and not exact configurations of 1s and 0s. That said, we should not expect quick results: we are yet to decipher language of cats and dogs despite living with them for centuries, and research into electrical communication of fungi is in its pure infant stage.”
