Our Favorite Shower Singers

Sometimes before we fall asleep, it makes us happy to think of all the wonderful things right under our noses that humans are just now discovering. Like mice roaring to their lovers and giraffes humming into the darkness. All kinds of “silent” animals turn out to be making a racket—we just didn’t know about it until recently. While they’re probably not going to form a new rock band any time soon, we think it’d be pretty killer if some of our favorite secret singers teamed up.

Strumming the bass: giraffes

01_MC_SS_Giraffe

Thought since forever to be silent giants, in 2015 researchers recorded giraffes humming tunes at night. They’re not sure yet why they hum, but it sounds like happy Tibetan monks wandering a country road.

Keeping the beat: baby fish

02_MC_SS_BabyFish

Grey snapper larvae pop and growl at each other in their little fishy nests. Those who watch them don’t think they’re mad; instead they might be checking in on each other in the dark when they can’t see.

At the mic: mice

03_MC_SS_Mice

Male Peromyscus sp. are more of the John Lenonesque crooners of the mouse world, while females play the Yoko, barking and roaring to their loves. All this mousy singing takes place in ultrasound, just outside our human hearing.

Adding whimsy: turtles

04_MC_SS_Turtle

South American river turtles (Podocnemis expansa) would play the kazoo in our band because, to be polite, their vocalizations sound a bit like tooting. These turtles have a lot to say to each other, but our favorite is […]

The Usual Suspects

Most entomologists have received a phone call along the lines of, “YOU WON’T BELIEVE THIS CRAZY BUG.” These calls often feature the same few species, and entomologists usually can make a quick tentative ID of the “usual suspects.” Here are some of eastern North America’s repeat offenders:

large_2
cicada.solo

Unlike their periodical cousins, adult dog day cicadas turn up each summer. Males sing to females using membranes called tymbals.1 The resulting sound, resembling a shaking metal sheet, is produced when the males flex their muscles, buckling the tymbals.

argiope

This spider has been wrongly accused! The golden garden spider is often found on the sides of homes. Females are large and vibrant, while males are small and drably colored.2 The female’s bold, aposematic coloring may be frightening, but she’s unlikely to bite. If found inside, try gently moving her outdoors to safety.3

belostomatid.solo

These voracious predators are aquatic and often become disoriented by porch lights as they’re flying to new habitats. To move this bug to safety, use a safe transport technique3; this species (and its close relatives) can deliver a painful defensive bite when stressed.4

centipede.solo

House centipedes are native to the Mediterranean but have spread globally with humans.5, 6 They have 30 legs (one pair per body segment) and often turn up in basements, where they prey on smaller invertebrates.7

Doodles from a Meeting

At Buzz Hoot Roar, we’re always telling you about what researchers are doing. This year, we let the researchers speak for themselves. At this spring’s Entomological Society of America’s SEB meeting, researchers made their own sciart about their work and wrote about it in classic BHR (brief!) style. Read on for four of our favorites.

Also, special thanks to Matt Bertone (@Bertonemyia) for this great idea. To learn more about the North American Coastal Plain’s new biodiversity hot spot, check out Matt’s American Scientist work here.

When Your Lover Could Just Eat You Up

Spider mating is like two serial killers making out. Sure, they’d like to hook up, but each one is also likely to kill the other. Because male and female spiders both walk around with venom-packed fangs and a penchant for the arthropod buffet, many species have come up with some cool behaviors to form a truce and get busy.

The Hopeless Romantic
To let their girlfriends know they’re available for love and not supper, male Argiope writing spiders strum out a love song on the females’ webs. Responsive females invite their boyfriends in for “coffee” and they go at it. But male writing spiders aren’t taking any chances with paternity.

hopeless_romantic

 

Once they mate, they die with their sex organs still clinging inside the female, using their whole bodies as mating plugs that remain there until someone eats them or they fall out.

The Cosby

To let females know they’re into them, Grass spiders, Agelenopsis aperta, flex females’ webs and then sway their abdomens from side to side in a hypnotic spider-love dance. Once females seem down to party, males release “spider roofies,” an airborne chemical that makes females pass out cold.

The Emotional Abuser

When they’re ready to roll, black widow (Latrodectus) females release a “come and get me” pheromone that draws males from all around. To reduce competition, an early arriving male quickly wraps up some of his potential girlfriend’s web, decreasing her pheromones’ attractiveness to other males.

The Gigi

Spotted orb weaver (Neoscona crucifera) males find a good thing and take no chances. If one finds a web with an immature female living in it, he’ll […]

Waterfall-Climbing Fish

If swimming against the flow was a fish-world Olympic event, climbing gigantic waterfalls would be an X-treme sport. 

In tropical island rivers, it’s feast or famine. Yearly rainfall fluctuates between gushing flash floods and desolate patchy pools. You might think such extreme conditions too inhospitable for fish.

Not for the thrill-seeking amphidromous fish! Their adventures start upstream, where adult amphidromous organisms live and reproduce.

On their upriver journey to reproduce, fish often encounter impassable migration barriers, like waterfalls. However, for  amphidromous gobies of the subfamily Sicydiinae, waterfalls are simply a conquerable challenge.

Whereas most fish have a pair of pelvic fins on their underside used for steering and stabilization, gobies (Gobiidae) have a single fused pelvic fin that holds onto rocks, like a suction cup, in turbulent waters. Sicydiinae gobies uniquely use their sucker fins in tandem with their mouths to slowly and methodically climb the faces of massive waterfalls.

Waterfall climbing has its benefits. Not only can these gobies access unoccupied upstream habitats, they can also evade voracious non-climbing predatory amphidromous fish lurking below.

Written by Patrick Cooney, a certified fisheries scientist who is unable to climb gigantic waterfalls. However, he is a leading expert in sampling and researching waterfall-climbing gobies in Puerto Rico and Hawaii. For his day job, Patrick trains fisheries scientists how to use electricity in water to safely sample fish for scientific purposes, and for fun, he co-founded The Fisheries Blog in 2012 with the purpose of sharing awesomeness about fish.  Patrick is known to media agencies as the guy who spoils […]

Are we human? Or are we microbe?

Microbes. EEK!!!

We spend a lot of time and money on antibacterial products. But despite our desperate scrubbing, we will never be free of microbes.

microbes1

In fact, our bodies’ microbial cells outnumber our human cells 10 to one! Which makes you wonder: If you have more microbial cells than human cells, are you human?

Of course! Humans play host to microscopic microbes, collectively known as the gut microbiome, that reside in the small and large intestine.

These microbial symbionts perform vital functions, especially during digestion.

microbes2
Many of these genes encode enzymes that digest food, such as CAZymes, which break carbohydrates into compounds that the body can absorb or excrete.
microbes3
If the composition of the gut microbiome changes, the body may lose the ability to perform certain functions, which could result in inflammatory bowel disease (IBD).

Even from the deep regions of our intestines, our gut occupants can influence much more than our bowel health.

microbes4
Studies report colonization of certain species of bacteria is more likely to be associated with depression and anxiety. Many researchers believe adjusting the composition of the gut microbiome may be a viable treatment for these disorders.

We may be human, but we are run by microbes, no matter how many times we wash our hands.

Announcing Buzz Hoot Roar’s new Artist in Residence!

We at Buzz Hoot Roar are pleased and proud to announce our newest Artist in Residence! Over the next year, Christin Hardy will use her unique graphic style to explore six science posts. Read on to learn more about Christin, and stay tuned to enjoy her excellent work.

Christin2

Who: I’m Christin Hardy, a graphic designer and illustrator living in the city of oaks, Raleigh N.C., and hailing from Seven Springs, a teeny tiny town in rural Eastern North Carolina where the livestock outnumber people.

Christin1

I graduated from NC State University with my bachelor’s in graphic design, and after a few odd jobs landed my current job as a graphic designer for the NC Department of Transportation. There, I get to work on projects from all sorts of divisions ranging from aviation and rail to highways and bike/pedestrian. One of my favorite projects was the poster I made for National Train Day in 2014:

Christin6

Why: I’ve always loved science and tend to choose extracurricular activities that reflect that, such as volunteering for the Duke Lemur Center (so much fun), working for the entomology lab at NCSU where I counted bee sperm for a summer (not as fun, but cool) and interning at the Smithsonian in Washington D.C. (definitely ties with the lemurs).

Christin3

So, when I got the email asking if I wanted to be the next artist in residence, I immediately gasped and said “YES!! Of course!!!” While I enjoy my work for the government, Buzz Hoot Roar gives me an outlet where I can […]

Middle school isn’t so different for animals.

It turns out humans aren’t the only ones with uncomfortable tweens. Animals suffer through their own in-betweener stage. Today on Buzz Hoot Roar, a very talented middle schooler illustrates the ins and outs of animals’ most awkward age.

1. They’re weird looking. Gangly and awkward, pubescent animals have their own pimple-faced, braces-type, please-bury-my-yearbook-photo style. Just take king penguins, moose, cicadas, lions and cardinals, for example.

2. They start getting fashion advice from their friends. When chimpanzees hit adolescence, they quit getting their mamas to do their hair in favor of a good grooming from friends. This helps form lasting bonds and keeps them from being the kid in class whose mama made his clothes.

cade_mompanzee2

3. Their voices change. Many animals get deeper voices as they get bigger. Red deer (Cervus elaphus) stags start trying to woo with their developing deep tones, but those voice-cracking preteens usually don’t stand a chance.

cade_deer3

4. They start hanging out with their buddies all the time. Instead of hanging at the watering hole with mama, elephants start to hit the mall, or at least pal around with their peers. Together they learn all sorts of things their mamas wouldn’t teach them. It’s the equivalent of a group of boys hiding a Playboy magazine under Billy’s mattress.

5. They start acting stupid. Youngsters tend to be heedless risk takers. Adolescent mice, for example, often show “unbalanced and extremes-oriented behavior, increased risk taking, […]
