Limericks, Lab Style

Thursday, May 12th, 2016

by Kristen Minogue and Heather Soulen

May 12 is Limerick Day, which among science aficionados is a time to wax poetic about the joys of research. Or not. When you’re an ecologist, sometimes research is muddy, smelly, or just plain weird. Electric skillets and marbles can become safety features. But then, the thrill of climbing a 120-foot tour can remind you why it’s all worthwhile.

While some limericists adhere rigidly to the anapestic meter, the one thing all limericks have in common is the familiar A-A-B-B-A rhyme scheme. So enjoy a few snapshots in verse about the lesser-known side of environmental science:

Ally Soren, Microbial Ecology Lab technician. (SERC)

The Sweet Smell of Science
Are those cow guts that make the lab stench?
Fatty acids make my stomach clench.
They smell like fish and feet
But the microbes must eat,
While my lab mates avoid my work bench.

Acidification and Low Oxygen Put Fish in Double Jeopardy

Tuesday, May 10th, 2016

by Kristen Minogue

Inland silverside (Menidia beryllina) reflected in aquarium. When threatened with low oxygen, fish often swim to the surface, where oxygen is more abundant but predators can more easily spot them. (SERC)

Severe oxygen drops in the water can leave trails of fish kills in their wakes, but scientists thought adult fish would be more resilient to the second major threat in coastal waters: acidification. A new study published Tuesday from the Smithsonian Environmental Research Center (SERC) shows that is not entirely true—where fish are concerned, acidification can make low oxygen even more deadly.

New Science Art Exhibit Examines People, Nature and Conservation

Mirror mosaic mushroom science art along SERC's Java Trail.

“DNA” can be found along the Java Trail.

by Heather Soulen

This year’s theme for SERC’s annual Open House is “Ecosystem Conservation: Where do you fit in?” In the broadest sense, this question got me thinking about people, ecosystem research and conservation. How do we conserve ecosystems and make realistic and manageable policies? As a scientist, science writer/communicator and artist, I decided to explore these question through art, specifically mosaics.

Using art as a way to raise awareness, express one’s thoughts or as a way to create dialog is one of the most wonderful and powerful things about art. Humans have been creating art for some 40,000 to 60,000 years and this timeline could extend farther back as new techniques and technologies become available and new cave art discoveries are made. Over the past decade some field stations and laboratories have incorporated arts and humanities into their programs. Many see it as an opportunity to communicate an agency’s mission, the scientific process, science discoveries and complex scientific concepts or areas of study. A recent essay in the Ecological Society of America’s Ecosphere explores the convergence of science, art and humanities and why it could be important to sustainability, ecosystem stewardship, ecosystem services and conservation strategies in the future.

DNA Offers New Hope for Saving Orchids

Thursday, March 24th, 2016

Melissa McCormick kneels over a cranefly orchid. (Yini Ma)

The secret is in the soil. In one of the oddest couples in the natural world, orchids need fungi to grow. But finding those fungi can be tricky, until a new study from the Smithsonian Environmental Research Center (SERC) used DNA to find them in more places than anyone suspected.

There are 14 federally endangered or threatened orchids in the U.S. alone, and dozens more are endangered or threatened at the state level. Figuring out how to restore any single species is difficult, because there are so many different kinds.

“You’re talking about the largest plant family in the world,” said Melissa McCormick, lead author and SERC molecular ecologist. Orchids grow from islands off Antarctica to the Arctic Circle and just about everywhere in between. “They grow in darn near every environment on Earth.” But for all their diversity, the planet’s 26,000-plus known orchid species have one thing in common: None can germinate in the wild without a suitable fungus.

Striped bass (Morone saxatilis) fry and copepods

Some fish like striped bass (Morone saxatilis) are born with a nutritive yolk sac. As striped bass develop, their yolk sacs shrink and their mouths develop. When fish are the stage where they are able to eat on their own they are called “fry.”

Hunt for a Missing Nutrient: Part III

Wednesday, February 3rd, 2016

by Kristen Minogue

Tom Jordan beside a V-shaped weir that tracks nutrients in a SERC stream. (SERC)

For years, a team of scientists has been trying to solve a mysterious disappearance at a drainage ditch on the Choptank River Basin, on Maryland’s eastern shore. Every year roughly 32,000 pounds of human-generated nitrogen enters the ditch’s watershed, from fertilizers, air pollution and other sources. But less than a third of that nitrogen typically flows out of the stream.

Tom Jordan has seen it before. A nutrient ecologist at the Smithsonian Environmental Research Center (SERC), Jordan has wrestled with the mystery of the missing nitrogen for more than twenty years.

“It feels like a sort of fatal attraction,” Jordan said. Two decades of trial and error and dead ends only fueled his determination to find answers. Now, according to a new January study, Jordan and his colleagues finally have some.

Jellyfish, cownose ray and blue crab snowflakes

by Heather Soulen

Winter storm Jonas is knocking on our doorsteps here on the East Coast, threatening blizzard conditions in some areas. Many of us will be hunkering down waiting for the storm to pass. We thought we’d create some fun Chesapeake Bay inspired snowflake designs for you and your family to create during the storm. Simply download the pdfs, print them out and follow the instructions at the bottom.

There are four designs to choose from, the easiest being the cownose ray and the most difficult being the blue crab. We’ve provided a blank template for you to create your own Chesapeake Bay or nature inspired design. Since this requires the use of scissors, parents please assist small children.

We’d love to see your snowflakes – be sure to post pictures of your snowflakes on our Facebook page or on Twitter!

Phragmites vs. Climate Change: Invasive Reed Better at Taking Up Carbon

One of the Chesapeake’s least favorite invaders could end up being an unlikely savior. The invasive reed Phragmites australis, a plant that has exploded across Chesapeake wetlands in the last few decades, is also making those wetlands better at soaking up carbon, ecologists from the Smithsonian Environmental Research Center (SERC) and Bryn Mawr College discovered in a new study.

The common reed, better known as Phragmites australis, grows in dense clusters up to 15 feet tall. North America has several native strains that have co-existed peacefully with many other native plants for at least 30,000 years. It is the invasive strain that arrived from Eurasia in the 1800s that has scientists and environmental managers worried. Eurasian Phragmites grows taller and denser than North American Phragmites, crowding out many smaller plants, and blocking access to light and nutrients. These changes in plant community have a ripple effect on animals that rely on wetlands for habitat.

“The fish communities, the insect communities, the soil and invertebrate communities, all these things change when Phragmites comes in,” says lead author Josh Caplan, a Bryn Mawr postdoc and visiting scientist at SERC. Often, those changes aren’t for the better. “Phragmites is doing a number to these ecosystems.” Click to continue »

Restrictions in Seaweed Agar-vate Scientists

Bivalves from Panama for Dermo disease study

by Heather Soulen

Last week Nature magazine published a news piece about how supplies of agar, a research staple in labs around the world, are dwindling. Agar is a gelatinous material from red seaweed of the genus Gelidium, and is referred to as ‘red gold’ by those within the industry. Insiders suggest that the tightening of seaweed supply is related to overharvesting, causing agar processing facilities to reduce production. Most of the world’s ‘red gold’ comes from Morocco. In the 2000s, the nation harvested 14,000 tons per year. Today, harvest limits are set at 6,000 tons per year, with only 1,200 tons available for foreign export outside the country. In typical supply and demand fashion, distributor prices are expected to skyrocket. As a result, things could get tough for scientists who use agar and agar-based materials in their research.

Agar is a scientist’s Jell-O. Just like grandma used to make Jell-O desserts with fruit artfully arranged on top or floating in suspended animation within a mold, scientists use agar the same way. Bacteria and fungi can be cultured on top of nutrient-enriched agar, tissues of organisms can be suspended within an agar-based medium and chunks of DNA can move through an agarose gel, a carbohydrate material that comes from agar. Agar and agar products are the Leathermans of the science world.
