Though the Smithsonian is home to both mind-bending art and groundbreaking science, these disciplines all too often appear as opposites. The myth of “analytical, left-brained” scientists and “creative, right-brained” artists creates a false dichotomy. However, art is an increasingly important way to communicate complex scientific ideas.
This spring, the Smithsonian Environmental Research Center (SERC) sponsored its first science illustration internship and experienced the power of bridging the gap between art and science. Anna Pedersen joined SERC for an 11-week internship, thanks to generous funding from the Maxwell/Hanrahan Foundation. Her intern project centered on creating a beautiful and original painting that helps communicate SERC science.

We may think we’re familiar with photosynthesis—the textbook recipe plants use to make food from light, water and carbon dioxide (CO2). But measuring it, particularly in natural settings, requires factoring in complex variables. Kelvin Acebron is a postdoc in the Quantitative Ecology Lab at the Smithsonian Environmental Research Center. He’s spent the last decade measuring photosynthesis and studying its regulation in the field. In this Q&A, Kelvin discusses photosynthesis in agriculture and in plants’ natural habitats (like tropical forests). He also shares what he’s learned in his global scientific journey. This interview has been edited and condensed for clarity.

Though currently a volunteer with the Chesapeake Water Watch project, this is not Maria Alejandra Ceballos’ first rodeo at the Smithsonian Environmental Research Center (SERC). Thirty years ago, Ceballos spent her summer interning at SERC’s Photobiology and Solar Radiation Lab with Pat Neale. Since then, she has made a career studying water quality and ecology, combining her passion for the outdoors with scientific pursuits.

When it comes to media coverage, not all invasive species get equal treatment. A new study found that out of 209 invasive plant species in the United States, half the media coverage over the past decade centered around just 10 species. Additionally, 80% of media coverage focused on only the top 25 invasive species.

Protecting the ocean and providing livelihoods and food security do not have to be mutually exclusive. A new study, led by the Smithsonian Environmental Research Center (SERC), shows that limiting human activity in parts of the ocean can bolster fish populations and the well-being of people living nearby.

Beaks and fins and claws, oh my!
Volunteers are central to most of the work that happens at the Reed Education Center, and caring for the animals in all of the fish tanks is no exception. Recently, we’ve added a brand new group of volunteers to help us care for our aquaria and ambassador animals. We call them our “Tank Team.”
The Tank Team volunteers chop food, weigh terrapins, scrub tanks and rinse filters every week. And the animals have been loving it! Having the volunteers take on these tasks allows the education staff to devote more of their time to developing and running programs for students and teachers, and it ensures that we are able to provide visitors with a beneath-the-surface view of what lives right off of the SERC dock.

Dr. Cindy Gilmour recently retired from SERC after 18 years serving as the principal investigator of SERC’s Microbial Ecology Lab. Prior to coming to SERC, Cindy was a researcher at the Academy of Natural Sciences Estuarine Research Center.Below, she shares some of the discoveries and environmental victories she has seen over her four-decade career.

It may have been a long time since you were a student. However, there are likely some educational experiences that have stuck with you long after you left formal education.
For me, I vividly remember learning about watersheds in elementary school. A group of environmental educators visited our class one morning to demonstrate how watersheds work. I watched as they added colorful ‘pollutants’ to rivers in a three-dimensional model of the Chesapeake Bay watershed. As we made it “rain” with spray bottles, the pollutants flowed toward the low-lying Bay where they combined into a brown liquid.
When I left the classroom, I was able to connect that the streams and rivers in the model were the same ones I spent my summers playing in. And I understood that local actions had larger consequences downstream. It was a critical moment that began my interest in environmental science.
This educational experience was memorable because it related to my “place”—an area with meaning.
The Smithsonian Environmental Research Center (SERC) and the City College of New York (CCNY) have joined forces to launch a new participatory science project in the Chesapeake Bay. Chesapeake Water Watch is a collaborative effort aimed at filling in the gaps of traditional water monitoring techniques by using remote sensing and community involvement.

There’s still time to defeat Phragmites, an invasive reed running rampant throughout the U.S., including Chesapeake Bay wetlands. But controlling Phragmites is not easy, and it cannot be done everywhere. A new study published January 24, 2023 revealed new insights into where Phragmites control stands the best chance of success, and what wetlands might look like as native species return.

Phragmites australis, also known as the common reed, began exploding across the Chesapeake in the 1970s. While a native strain exists, it has been hard-pressed to compete with the invasive strain from Eurasia. It forms dense stands with shoots that can grow over 15 feet tall, eventually crowding out native plants.
