Rob Aguilar takes photos of all DNA barcoding reference specimens they collect in the Chesapeake Bay
Rob Aguilar of SERC’s Fish and Invertebrate Ecology Lab co-authored a DNA barcoding paper this past September in the journal Environmental Biology of Fishes. Rob spoke with us about his paper and the DNA barcoding work going on in the Fish and Invertebrate Lab. While the term DNA barcoding may seem difficult to understand, it’s easiest to think about it as a uniquely identifiable species level code.

In our last installment of The Dark Side of Taxonomy, we’ve saved one of the most fear inducing scientific names for last. We wouldn’t have done due diligence this Halloween season if we didn’t mention him. In this piece we present a small collection of organisms that in some instances have suffered the same etymological fate – a scientists with a proclivity for dark humor. Here we spotlight organisms that carry the infamous name of an angel who fell from grace.
Delving deeper into the dark side of taxonomy, we forge forth into the ether to uncover obscure and wickedly inspired scientific names. What’s in a scientific name? As described in The Dark Side of Taxonomy: Part One, some scientific names for organisms have dark and twisted origins. In part two of this three-part series, we peek behind the thin gauze-like veil, fearlessly sifting through time and lore to deliver a new collection of gruesome scientific names. Here we share ancient tales of Greek mythology, an Italian literary genius from the Middle Ages and the unforgiving Underworld.
Ten years ago, on August 28, 2005, Hurricane Katrina nicked south Florida and entered the heat-charged waters of the Gulf of Mexico, transforming from a Category 1 hurricane into a super-charged Category 5. In the early morning hours of August 29, it ripped through Louisiana and Mississippi. Thousands died, and hundreds of thousands of homes and businesses were destroyed. Today, much of the Louisiana and Mississippi coasts, and its people, are still recovering from the devastation.
When Katrina hit, some coastal marshes east of the Mississippi River lost approximately 25 percent of their area. In the decade that followed, salt marshes and wetlands in Louisiana have continued to disappear in some places, but not others. The scientific community soon zeroed in on keeping marshes healthy, since, as one scientist remarked “A healthy marsh is pretty resilient, A stressed marsh – storms will physically break the marsh down.” Marshes and wetlands are ecologically and economically important ecosystems. During storms they act like buffers, reducing storm surge and flood damage, but only if they’re healthy. The question is, what factors make a marsh strong or weak? Click to continue »
Last year, Pantone chose Radiant Orchid as their 2014 color of the year. Pantone is the authority on color. Their color choice affects a variety of industries from fashion and make-up to home interiors (e.g. paint, upholstery, etc.). Once again orchids have sashayed their way into our everyday lives and in very big ways. Journey with us as we explore just a few fabulously fierce fashion pop-cultural orchid moments.
Christian Dior’s to Die for Couture:Paris Haute Couture Autumn/Winter
Belgian designer Raf Simons joined fashion power house Christian Dior in 2012. Just two years later at the 2014 Paris Haute Couture fashion show, he wowed the audience with walls dripping with 150,000 live orchids and an equally jaw-dropping runway collection of embroidered blooms and floral-inspired silhouettes. The Fashion Channel said the show felt “divine and ethereal, with models resembling graceful nymphs walking elegantly in an antiseptic white circular Olympus with silver walls adorned with pristine white orchids.” C’est bon! We don’t think we could have said it any better!

Research shows that music affects our brains and our bodies. It can make us laugh, cry, give us chills, empathize and remember events or single seemingly fleeting moments that we’ve long forgotten. When it hits the right cords, music can increase heart rate, dilate pupils, increase body temperature and release the neurotransmitter dopamine, a chemical which plays an important role in our brains, particularly the reward centers of the brain. The same has been said about orchids, the hunt for orchids and in Victorian era, the eroticism surrounding orchids.
Since the 1960s, there have been several musical groups, albums and songs with orchid-centric names or themes. Journey with us as we explore how orchids have conquered music pop-culture.
There’s a reason orchids are called the smartest plants on Earth. Several, in fact, and not all of them good. Some orchids can be crafty, devious pretenders, using their fragrance to trick insects into pollinating them but giving no nectar in return (we’re looking at you, Dragon’s Mouth and Fairy’s Slipper). But most lessons from the orchid world are more encouraging. Many remain beautiful in winter and thrive after fire. In the final days of the semifinals of the Smithsonian Showdown, we’ve adopted a new motto: What Would Orchid Do? After all, they have been around for 80 million years. Any species that survived from the age of the dinosaurs has to have done something well.
“Orchids aren’t just pretty. And a lot of them aren’t even pretty at all. But they are sexy, and that’s really one of the things that makes them unusual among flowers. It was believed that orchids sprang up wherever animals had been mating. And in Victorian England, women weren’t allowed to have orchids because the form of them was thought to be too erotic and too sexual, and it would be too much for a woman to bear, having a flower that sexual in her possession.” -Susan Orlean, transcripts from NOVA’s “Orchid Hunter”
There’s no denying, orchids are pretty darn sexy plants. And it because of their sex appeal, they’ve sashayed their way into just about every aspect of pop-culture. They’ve glammed their way into movies, TV, music, fashion and literature, and we didn’t even realize the spell they cast until it was too late. Bewitched, bothered and bewildered, we didn’t even realize how inescapable they are in our world. Here we explore a few examples of how orchids deftly made their way into pop-culture literature.
An old Ojibwe legend tells of a village visited by plague. It was the dead of winter and many died, including the village healer. To save the community, a young girl made a dangerous journey through the snow to find medicine for the sick. She succeeded, but on the way lost her moccasins, leaving a trail of bloody footprints in the snow. When spring arrived, the bloody footprints put forth moccasin flowers—better known today by their Western name, the lady’s slippers.
Origin stories of the lady’s slipper orchid exist among many Native American tribes, and the details change. (Were the flowers yellow or pink? Did she make the journey in place of her sick husband? Did the flowers come from her footprints, or the bandages on her feet?) But at the root lies a more basic question: What was so important about this orchid?
William Swainson probably painted this orchid sometime between 1789 and 1855.

Legend says it all started with a single orchid bloom. This bloom, an accident, sparked a phenomenon so pervasive in Victorian England that its name, orchid delirium, was shortened to orchidelirium, a d excised to indicate the oneness of orchids and madness.
The story begins like this: In 1818, a man named William Swainson sent plants from Brazil to London, using what he believed to be parasitic plants as packing material. When the package arrived, one of the plants was in bloom. Its vivid hue and strange shape were unlike anything most European eyes had ever beheld in the way of flowers. Europe fell in love. And so began orchidelirium, the European obsession with orchids. Click to continue »
