Think back to your early childhood science classes. Was there
ever a time you had to watch a plant grow? Your first natural sciences teacher may have used plant growth to explain basic concepts of plant biology. The process is a rewarding learning experience for students to observe their hard work pay off as those first few leaves sprout from the soil.

Now, imagine the work you did was part of a larger scientific project, with real-world applications. That is exactly what four sixth-grade classes are doing this year at Walker Mill Middle School. Located in a Capitol Heights neighborhood of the Prince George’s County school system, Walker Mill is one of seven schools in the Maryland area working with the Smithsonian Environmental Research Center (SERC) on a project called “Orchids in Classrooms.”

Don’t panic. The new robot greeting visitors at the Reed Education Center isn’t about to stage a technological coup over the SERC campus. But it can pose for selfies, tell people about SERC programs and break out a dance move or two.
The robot goes by the name Pepper. Technically, Pepper has no gender, though most visitors—and a few staff—have taken to calling the robot “she” by default. The Smithsonian received a team of Pepper robots in February from SoftBank Robotics, to test out in their museums and other programs. Two Peppers went to the Smithsonian Environmental Research Center (SERC), where staff and students are programming them to interact with the public. Click to continue »

It’s a true story of “grassroots science.” A team of over two dozen researchers set out to estimate how much carbon tidal wetlands across the U.S. can store. But the official datasets didn’t give them much info to work with. So they pooled their resources, creating a new dataset of nearly 2,000 wetland soil cores.
Their final estimate: Nearly 800 million tons of carbon may lie buried in the tidal wetlands of the contiguous U.S. The team published the discovery June 21, in a new study in Scientific Reports led by the Smithsonian Environmental Research Center. The study also leaves another major legacy. The 1,959 soil cores they compiled could help finally unlock some secrets of wetlands, ecosystems that have been overlooked for centuries.

Sharks. They’re everyone’s favorite underwater enemy. Between nerve-wracking dramas like Jaws to stories about prehistoric mega-sharks, we have all but made the shark species a completely fictionalized being. But scientists at the Smithsonian Environmental Research Center (SERC) are hoping to change that.
Charles “Chuck” Bangley, a marine ecologist at SERC, travels up and down the East Coast catching and tagging four species of sharks found in the Chesapeake Bay and along the Atlantic: smooth dogfish sharks (Mustelus canis), bull sharks (Carcharhinus leucas), blacktip sharks (Carcharhinus limbatus) and dusky sharks (Carcharhinus obscurus).

ecosystem conservation ecologist
One of the unexpected perks of my life as a scientist has been the opportunity to travel for work. As a grassland ecologist, my studies have taken me to South Africa and Tanzania to investigate the roles of fire, grazing, and nutrient availability in determining plant growth and species diversity. In these exotic field sites, I would drive by impalas, zebras, elephants, giraffes, cheetahs, lions, and leopards before arriving at my experimental plots. Then I would spend my day working in the hot sun to survey the plant communities in my plots, all the while guarded by a park ranger with a loaded rifle to protect me from the very animals I marveled at on the way to the field site. (Thankfully those rifles were never fired during my trips.) With grasslands all over the world, I have many more grassland types on my research wish list, including the Mongolian steppes, the Pampas of South America, the Cerrado of Brazil, and the rangelands of Australia and Europe.

SERC researchers race to find out how higher temps will affect coastal wetlands

Wetlands are typically filled with the sounds of crickets chirping, bees buzzing and frogs croaking. But at the Smithsonian Environmental Research Center (SERC), those are all accompanied by the whirring of motor-powered pumps. These pumps are driving air from hexagonal carbon dioxide chambers to a greenhouse gas analyzer, helping scientists create a “wetland of the future.”
Scientists at SERC are attempting to predict how the warming climate and rising carbon dioxide levels will impact coastal wetlands with an experiment called SMARTX—Salt Marsh Accretion Response to Temperature eXperiment. It’s one of many futuristic experiments on the center’s Global Change Research Wetland.
“Wetlands are a really important part of our planet in terms of storing carbon, and we’re hoping to get an idea of how higher temperatures will affect them,” said Genevieve Noyce, an ecology postdoc at SERC, as she moved among grass-covered warming plots, measuring gas exchange over five-minute intervals.

An army of invading crabs has disappeared. But scientists are skeptical about whether they’re gone for good, or just hiding. As warmer temps lure people onto the water, Smithsonian scientists are asking boaters to report any sightings of the elusive Chinese mitten crab.
In 1992, a team of fishermen unexpectedly caught a Chinese mitten crab while trawling for shrimp in southern San Francisco Bay. From there, sightings of the brown, furry-clawed crustaceans exploded. In 1998, nearly three quarters of a million appeared in the North Bay alone. The mitten crabs threatened to collapse river banks with their burrows and made fishing nearly impossible in some places, as they clogged gear, stole bait or ate trapped fish.
“It was spectacularly abundant. A true outbreak,” said Greg Ruiz, a biologist with the Smithsonian Environmental Research Center (SERC). “And it clogged the water intakes. Water is the economy in California.”
Mitten crab numbers remained high through 2005. And then they vanished. Chinese mitten crabs haven’t been seen in California since 2010. Click to continue »

If a gardener told you that her plants had died and had come back to life years later, you might think she had gone crazy. But actually, she may be on to something.
Some fully-grown plants can “hibernate” in the soil for up to 20 years, researchers from the Smithsonian Environmental Research Center (SERC) discovered in a study published in the May issue of Ecology Letters.
The so-called “Rip Van Winkle” plants, nicknamed after the fictional character who slept for two decades, include many species of orchids and some ferns. Click to continue »

The sing-off begins when the sun goes down. Every night off the coast of Bocas del Toro, Panama, Bocon toadfish start calling from their burrows, trying to win over females by showing off their vocal talents and drowning out the competition.
If you’ve never heard of the singing toadfish, you’re not alone. They don’t have the charisma of dolphins or whales. They’re mud-colored reef dwellers, with bulging eyes, puffed-out cheeks and fleshy barbels dangling from their mouths. By most human standards, the toadfish isn’t exactly the prettiest fish in the sea.
“It’s kind of like a troll that lives under a bridge and sings,” said Erica Staaterman, a marine biologist who recorded individual toadfish songs in Panama for a new study published this month.

For as long as I live, I will never forget the look on my daughter’s face the first time she saw a gorilla at the zoo. She was just over a year old and had started imitating the animal noises of those in her books, so it seemed like the perfect time to introduce her to these animals in person. Our first stop that day was the great apes. I was holding her and pointed to draw her attention to the gorilla. At first, her expression didn’t change…until the gorilla started to move toward us. The closer the gorilla got to the glass, the larger my daughter’s eyes became. She then pointed and said “monkey.” The look on her face said it all – animals weren’t just images in books that made her parents erupt with funny noises; these things were real and they moved!
