Food for Thought: Cooking for Invasive Beetles

Smithsonian Environmental Research Center (SERC) intern Cole Caceres has two passions: science and cooking. He enjoys doing research and adding to the larger body of knowledge, but he hasn’t given up on owning his own restaurant. When he’s not studying nitrogen filtration as a laboratory assistant at the University of California, Davis, he’s probably watching Food Network or frying chicken wings in a sweet soy sauce glaze.

But Caceres found the perfect mix of his interests as an intern with SERC’s Terrestrial Ecology Lab. There, he cooks for invasive Japanese beetles, hoping to help shed light on their dietary preferences so that plant conservation initiatives can be more fully informed—one beetle bite at a time.

Sink or Swim? Divining the Fate of Life-Giving Wetlands

Friday, August 12th, 2016

By Emily Li

You might have heard of The Giving Tree, a children’s picture book by Shel Silverstein about a boy and a tree. As the boy grew, he began to want more from the tree, and the tree happily gave and gave and gave: her apples, her branches, and even her trunk. While Silverstein’s heartbreaking story was a fiction, the plot is happening in wetlands around the world—and this time, it’s for real. Marshes improve water quality, mitigate hurricane damage, sequester atmospheric carbon, and serve as ideal habitats and nurseries for wildlife. In return, as sea levels rise, they’re in line to be the first casualties.

That said, marshes are hardly a serene paradise. To Smithsonian Environmental Research Center intern Jefferson Riera, wetlands are ruined shoes caked in mud. Wetlands are wasp stings on his lips. Wetlands are spider webs of scratches from marsh vegetation. Wetlands are sunburns so severe his skin doesn’t match itself anymore.

And yet, he knows that they’re worth protecting. That’s why he, and the rest of SERC’s Ecological Modeling Lab, are working to develop a baseline understanding of local marsh elevation to educate policymakers on the state of wetlands—before their fates are sealed by the sea.

The Mystery of the Muddy Creek Restoration

One year ago, a team of scientists at the Smithsonian Environmental Research Center set out to restore a stream running through its campus in Edgewater, Md. No one ever said it would be simple.

At first glance, the restoration of Muddy Creek seems to be a closed case. Before the project began, the creek’s severely eroded banks were disconnected from its floodplains, turning the stream into a raging river during storms that stripped nutrients from the system and dumped them in the Chesapeake Bay. Now, after a facelift in January, the creek is nearly unrecognizable. Its gentle banks cradle the wide, slow-moving stream littered with leaves, ferns, and an abundance of other plant life. Choruses of croaks fill the air, accompanied by the hum of insects, bird chatter, and the occasional splash of frogs retreating into the cloudy water.

But another layer of mystery is clouding the waters. A mat of red Leptothrix bacteria coats some sections of the site, leading SERC senior scientist Dr. Thomas Jordan and his colleagues to ask a host of new questions. Are the bacteria harmful to the ecosystem, or an important part of the food web? Are they a short-term phenomenon or a permanent fixture to the stream? Exactly how much area do they cover? One SERC intern is hoping to find out.

Making Noise About Marine Sound Pollution

In high school, Smithsonian Environmental Research Center intern Michelle Hauer fell in love with sound. She discovered the cello, which she insisted on bringing to her internship this summer despite having limited space and housing. But her affair with sound didn’t stop there, even as she was exploring her interest in science. While still in high school, she wrote a paper on the effects of naval sonar on marine mammals. Then, while attending DePaul University, Hauer came across the relatively new field of soundscape ecology through a Chicago-based organization called Chicago Wildsounds—and she hasn’t looked back. Now, as a summer intern in SERC’s Fish and Invertebrate Ecology Lab, Hauer is studying the darker side of sound by researching how noise pollution can affect marine wildlife in the Chesapeake Bay and beyond.

An Acid Test for the Coasts

Watching educational programs like Animal Planet or That’s My Baby—a series that documents pregnant animals—might evoke memories of flickering classroom projectors for most. But for Jasmin Graham, an intern with the Smithsonian Environmental Research Center (SERC), these shows were her childhood. Her love for marine science and wildlife followed her through high school science fairs and university research on shark genetics at the College of Charleston. Now, at an internship with SERC’s Ocean Acidification Lab, she studies acidification not in the open ocean, but in a far more dramatic arena, where the marine celebrities she grew up with may be at risk.

How Clay Caterpillars Help Unlock Biodiversity’s Secrets

Anna Nordseth, a summer intern for the Smithsonian Environmental Research Center’s Terrestrial Ecology Lab, wasn’t surprised to be taking work home the first week and a half of her internship. What she wasn’t expecting was to be making nearly a thousand clay caterpillars.

Each caterpillar began life as a half gram of green clay, with a wire spine and ends rolled into a worm-like silhouette. By the time Nordseth had finished—several podcasts and three seasons of House of Cards later—she had 900 caterpillars and the hand cramps to prove it. But she was ready to begin her research.

Bucket Buffets Divulge Deer Preferences

Imagine a swimming creature. It holds an antlered head above the water as its skinny, hooved legs tread underneath. A black stripe runs from its head to its tail, outlining a waggling white rump, revealing it to be a sika deer.

In 1916, a man named Clemment Henry released between four and six sika (the number isn’t certain) for hunting on James Island, off Maryland’s Eastern Shore. But it turns out sika are great swimmers—by 1962 they migrated to the Delmarva Peninsula and they now occupy every county of the lower Eastern Shore. Click to continue »

Smashing Logs to Uncover a Body-Snatcher’s Secrets

Darin Rummel, intern in the marine invasions lab at the Smithsonian Environmental Research Center (SERC), raises a piece of wood twice the length of his arm and slams it onto a dock in the Patuxent River at Greenwell State Park in Hollywood, Md.

The soggy stick crumbles and a white-fingered mud crab scurries from the wreckage. Rummel adds the crab to a modest collection in a Tupperware container and raises the stick above his head again. Connor Hinton, another marine invasions lab intern, wades into a cove of muddy water in search of more crab-concealing wood. Click to continue »

Frigid Days Equal Fewer Bluebird Eggs

Eastern bluebirds resemble flying, fist-sized jewels. Males are sapphire colored—royal-blue heads, backs, and wings contrast with rust-colored chests. Females are more gray than blue, but their wings are subtly tinted the same sapphire hue.

Since 2008, citizen scientists have monitored bluebirds at the Smithsonian Environmental Research Center (SERC). The Bluebird Project is citizen science intern Caroline Kanaskie’s self-proclaimed “baby” this summer. She is uncovering why bluebird numbers at SERC have been lower than usual.  Click to continue »

“Science Ninjas” Capture Bugs at Camp Discovery

“Camp Discovery!” shouts Smithsonian Environmental Research Center (SERC) education intern Josie Whelan.

“SCIENCE NINJAS!” a dozen 6- to 8-year-old campers respond as they strike ninja-esque poses. This is a callback, used by the three education interns—Henry Lawson, Addie Schlussel, and Whelan—to grab the attention of talkative future first- and second-graders at Camp Discovery. The education interns designed Camp Discovery this year, organizing a week of visits to SERC’s forests, fields, docks, and wetlands to foster understanding and respect for nature in campers.
