Wired Nature

As winter winds disperse prairie seeds and fragrant pinecones tumble down, Bianca Rosenbaum is busy collecting. As much as she would love to forage through the seasonal natural materials outside of her office at the Chicago Botanic Garden, that’s not what she is after these days. Rather, she is gathering data.

Rosenbaum manages data from her colorful office.

Seated at her desk in the Daniel F. and Ada L. Rice Plant Conservation Science Center, Rosenbaum taps away at her computer’s purple keyboard. The Garden’s conservation science information manager is busy finishing her masterpiece—a searchable collection of visual and numeric plant data. The new product is a one-stop-shop for information previously housed in three separate databases and accessible by few.  

Named the Science Collections database, the project centralizes the Garden’s data on seed collections, herbaria, and plant DNA. For the first time, the information is accessible online by anyone from international scientists to curious children.

“We saw this great opportunity to combine our databases and be able to cross reference collections,” she said. “It’s been very exciting. It’s one of my biggest, most challenging projects. It feels extremely rewarding.”

Since she began working at the Garden in 2002 as an expert in Microsoft Access, Rosenbaum has overseen the safekeeping of the data in all three of these areas as well as other Garden research collections. In just a few years, the way the information was stored and managed became outdated as technology progressed. She was thrilled with the opportunity to advance its management system.

When the Science Collections project began four years ago, one of her first tasks was to identify data used by all three databases and merge them into common tables to eliminate repetition and guarantee standardization. The result was a complicated set of linked tables that comprise the structure for the final product—called a relational database.

She then merged all of the data on each species. Now, rather than going to different databases to find all of the herbarium, seed, and DNA information recorded about a plant, it can be found in one place. 

Rosenbaum then worked with the Garden conservation GIS lab manager, Emily Yates, to add a spatial component to the data by mapping plant locations, which are linked to each collection record. Lastly, she built a web page to serve as a portal from the database to the internet.

Data from the Garden’s Nancy Poole Rich Herbarium are mainly visual, with 17,000 images of pressed plants alongside notes about location and related details. Information from the Dixon National Tallgrass Prairie Seed Bank includes high-resolution images of seeds from 2,600 species. The program also includes notes about whether the Garden houses material that may be accessed for DNA sampling for a given plant. The records include information on all classifications of regional plants, and some international. Only those labeled as threatened or endangered are not shown on a map.

“This job has totally changed my outlook,” said Rosenbaum, who had no real interest in botany before coming to work at the Garden. “I feel very fortunate that I’ve been here and I’ve been able to combine both the tech world and the environment.”

As a child, she grew her love of technology with encouragement from her parents—an engineer and electronic assembler. She went on to study computer engineering in college, and gained work experience with coding and data management. As a Garden employee, she has coupled those computer skills with a new set of plant-related skills. She is now comfortable with plant names, discussing scientific processes, and even growing her own vegetable garden at home.

Although she spends much of her work day glued to her computer screen, Rosenbaum does find time to look out her window, or step outside to connect with her subject matter. “I think it’s very easy to not notice this world when you are in the tech world, or the business world,” she said. “Now I can connect the two and know what it is I am working on and see what I am working to protect and conserve.”

Rosenbaum often strolls the Waterfall Garden in warm months, but she especially looks forward to spending time in the peaceful Dixon Prairie.

The recently launched database is now open to exploration at www.sciencecollections.org. Check back in coming months for Rosenbaum’s forthcoming addition of advanced search options.

Who’s On Air?

On December 4, 2013, the Garden became both the first public botanic garden—and the first Chicago cultural institution—to host a live field trip, with approximately 1,000 students across the country using Google+ Connected Hangouts on Air.

Our field trip topic was the impact of an invasive species on an ecosystem—specifically, emerald ash borer on our native ash trees. We wanted to make this complicated issue relevant and interactive for fifth- and sixth-grade students.

There are many fun things you can do with a live broadcast. The complex subject of balanced ecosystems and invasive species needed something unusual to capture students’ imaginations and attention. Our solution: begin our field trip with an original graphic comic about the emerald ash borer (EAB), and conclude by cutting down an infected tree during our broadcast. The live broadcast format also allowed our educators and horticulturists to go off script for some on-screen improvisation. 

Taking advantage of our medium, we presented from multiple locations—switching to read and show our comic book, present GIS (Geographical Information Systems) maps illustrating the spread of EAB in the U.S., view EAB larvae under a microscope in our science lab, and show how to diagnose the damage on—and treat (or remove)—an infected tree in the woods. The finale was cutting down the infected tree—live on camera! Before we signed off, we had an interactive Q&A between classrooms and Garden experts.

PHOTO: An auditorium of kids watches our broadcast on a projection screen on stage.
An auditorium of seventh graders in California tunes in to our broadcast.

A series of technical and dress rehearsals—one with the three participating classrooms—were necessary to troubleshoot the quirks of Google+ Hangout on Air. We chose three classrooms from across the country as active participants who were able to ask questions on camera, and be seen by our experts and others tuned in. (Viewing classrooms can still participate by typing in questions during the broadcast.)

From a technical standpoint, it was critical to know the limits of this technology. Google Hangouts currently allows up to ten screens to actively participate in an on-air event, and our entire program had to be done live, as Google Hangout on Air does not allow for streaming video. We used four of our allotted screens at the Garden: one for our graphic novel with narration, one in the lab, and two in the field. The screens were controlled through a central operator (me!) who acted as an on-air producer, switching from one screen to another to control the on-air experience. We used two smartphones to transmit from the field, and tested several models with different operating systems and carriers to maximize image quality (especially in the woods), and keep gaps in the transmission to a minimum. Macintosh computers provided the indoor Garden screens; one was dedicated to the microscope, and the other used its built-in camera. The computers were hard-wired to the Ethernet network to ensure the best transmission possible. Delays were a minor issue: even under the best of circumstances, we experienced a short lag switching from user to user. This was particularly problematic when fielding classroom questions.

While a virtual field trip is not a substitute for an actual visit to the Garden, it can offer something very different and unique, bringing together classrooms from all over the country. Virtual classrooms can also enrich classroom activities in schools facing budget shortfalls and scant funding for field trips. This new tool from Google can help us (and others) raise awareness about topics that affect us all from local to global impact. Follow us on Google+ to be alerted to our next virtual field trip and other Garden updates.

Using Genetics to Rescue a Rare Desert Shrub

Huddled on a sand dune, the small community of bristly Lepidospartum burgessii plants would be easy for most of us to overlook. But to scientists from the Chicago Botanic Garden, the rare shrubs shine like a flare in the night sky. This is one of two known locations of the species worldwide—both in New Mexico—and the center of a rather dazzling rescue mission.

Evelyn Williams, Ph.D., a Garden postdoctoral research associate, is pulling out all the stops to save the sensitive species. Commonly called Burgess’ scale broom, it has suffered from a mysterious lack of seed production since the late 1980s.

Burgess’ scale broom (Lepidospartum burgessii) are among the tallest plants in their New Mexico location.

Standing about five feet tall, the silvery-green plants only grow on gypsum dunes. They possess unique characteristics that allow them to help stabilize sand dunes in the desert conditions where they live.

“I’m interested in how we can use genetics broadly to address conservation and ecological restoration questions,” said Dr. Williams. Her curiosity led her to the Garden in 2011 to join a team of genetic experts for this formidable undertaking.

The team suspects that, because the two populations of Lepidospartum burgessii are relatively small, the existing plants have interbred and are now too closely related to pollinate one another—which means they cannot produce seeds and create new plants.

Williams set out to confirm this theory, gathering plant cuttings during summer fieldwork in 2013. She hoped to grow the cuttings into full plants that she could cross-pollinate and study at the Garden. She also took samples from 320 plants back to the Garden. There, using a microsatellite technique, she recorded the genetic pattern of each plant, noting similarities and differences.

“When we have all of these different shrubs from a population, we want to use a fine genetic tool to tease apart genetic variations,” she explained. The microsatellite approach allowed her to identify genetic markers occurring in multiple plants down to the finest level of detail.

The results were encouraging. Williams found enough genetic diversity within the two populations that they should be able to cross pollen, or DNA material, and produce seeds. “Because there is diversity in these populations, we’re really hopeful that if we do a genetic rescue we can get some seeds in these two different populations,” said Williams. A genetic rescue, she explained, is when a species is revived with the addition of new genes, which normally occurs during pollination.

That day didn’t come right away, as the cuttings failed to grow in the Garden greenhouses. Accustomed to the trial and error process of scientific discovery, Williams moved on to her backup plan.

She returned to the field in October, where she personally carried pollen-filled flowers from one population of plants to another, brushing the fluffy yellow blooms against other plants that may accept their genetic material. With plants as much as one mile apart, it was a process of patience and precision.

She will soon look for seeds in the resulting buds from that pilot study with an x-ray machine in the Garden’s Harris Family Foundation Plant Genetics Laboratory.

Williams is poised for the challenge of whatever she may, or may not, find. Ultimately, she hopes to convey a successful technique to land managers who carry out the daily work of furthering the species and enriching the biodiversity of the southwestern landscape.

“I really like that as part of the Garden we can help these public agencies and use our knowledge of genetics and conservation to stabilize and increase some of these rare populations. That’s really important to me,” said Williams.

She has been intent on advancing conservation science since childhood, inspired by her aunt, an ecologist. Her interest grew into expertise as she studied the genetics of ferns while earning her Ph.D. in botany at the University of Wisconsin.

In winter at the Garden, Williams takes every opportunity to walk through the Elizabeth Hubert Malott Japanese Garden. “I like being here in the winter and seeing a side of the Garden that’s unexpected: the snow and the beautiful structures in the Malott Japanese Garden,” she said.

Perhaps it is that perspective, of looking for the unexpected, that will unlock the mystery of Lepidospartum burgessii one day soon.

Notes from the 5th Global Botanic Gardens Congress

I’ve just touched down at home after five days in New Zealand at the 5th Global Botanic Gardens Congress; 329 delegates from botanic gardens and arboreta from 45 countries gathered together in Dunedin, New Zealand, to learn how to strengthen our horticulture displays and plant collections, education and visitor programs, and plant conservation science. Our Chicago Botanic Garden motto is “Save the Plants, Save the Planet,” and what an amazing experience it is to spend time with people—mostly brilliant plant scientists—who share this passion and mission, and who will travel from every corner of the globe to help realize it.

Here are two particularly good slides that show some of the big-picture goals presented by Peter Wyse Jackson, Ph.D., president of the Missouri Botanical Garden and chairman of the Global Partnership for Plant Conservation (GPPC).

I had the honor of representing our garden in Chicago four times throughout the Congress, organized by Botanic Gardens Conservation International (BGCI).  I presented at a symposium with colleagues from England, Austria, and Jordan about botanic gardens’ role in social change; chaired a panel of compelling speakers from Jordan, Mexico, Australia, and the U.S. who shared examples of how to engage communities in conservation; was challenged by the audience at an open forum with Stephen Blackmore, Ph.D. (Edinburgh), Dr. Tim Entwistle, Ph.D. (Melbourne), and Jack Hobbs (Auckland); and delivered a plenary address. If you want to see the range of topics and gardens represented, take a look at the BGCI Congress site; the Twitter comments #BGCI2013 also give highlights.

My Chicago Botanic Garden colleagues Greg Mueller, Ph.D., and Kayri Havens-Young, Ph.D., also attended and presented their work (and we had a lot of fun, too).

Being relatively new to the field of plant conservation, I set as one of my Congress goals the memorization of international conservation acronyms. To effectively make our way in any land we need to learn to speak the language!

This is a PowerPoint slide of inside-baseball acronyms from one of the presentations.

So now, after writing down and decoding (i.e., asking the nice person next to me for help or drawing on the seemingly endless patience of my colleague Greg Mueller), the acronyms I heard, I am now semifluent (in that college French kind of way). Below, I offer a plant-conservation-centered sample of what I’ve learned—hopefully this primer will be helpful as you get involved in plant conservation. If you catch a mistake, please let me know!

Filming “Plants Are Cool, Too!”

This past spring I was asked by a friend and colleague, Chris Martine, to be featured in an upcoming episode of Plants Are Cool, Too! 

A few months later, in August, we taped episode 4, focusing on my work with plants and pollinators, and episode 5, which will feature the work of Mike Moore of Oberlin College on gypsum-endemic plants (to be released later this year).

So what exactly is Plants Are Cool, Too!?

Chris Martine created the web-based series Plants Are Cool, Too! to address a gap in the nature show genre: there are no shows focused explicitly on plants that might engage people, from elementary school kids on up. He set out to create a series focusing on some of the coolest plants, their stories, and the scientists who study them. As of today, four episodes have been released:

Episode 1 — The Pale Pitcher Plant
Episode 2 — Fossilized Forests
Episode 3 — Undead Zombie Flowers of Skunk Cabbage
Episode 4 — Desert Plants and Marathon Moths (my show—see it at the end of this post!)

Adventures with botanists and filmmakers

So what does it take to create an episode? And how about two episodes at once, in just three days? Certainly, lots of planning, people who know the lay of the land, and a fantastic film crew. Thankfully, Chris is really good at what he does—the team of people he pulled together couldn’t have been better.

Our first site for filming was Yeso Hills, just southwest of Carlsbad, New Mexico. We arrived at the golden hour, when the sun is near the horizon and casts a golden light on everything. As we turned off the highway onto a gravel road, we encountered a sea of sundrops (Oenothera hartwegii and O. gayleana). I had a hard time containing my excitement. I’ve seen photos of populations like this, but nothing like it in person. There were plants everywhere, hundreds of them, their yellow flowers on full display, glowing magnificently in the setting sun. I suspected it would be a fantastic night for hawkmoths—how could they not be drawn to this fantastic population? So many plants, so much nectar! It was going to be awesome.

Until it wasn’t.

The sun set and we taped a handful of things: setting up the “moth sheet,” collecting floral scent, nectar, size measurements. And we waited and waited for the hawkmoths to show up; after about two and a half hours, we headed toward Carlsbad for the night. While I couldn’t imagine a better place for a hawkmoth to be, they clearly could.

The following morning, we headed for White Sands National Monument, home of the world’s largest deposit of gypsum sand dune field, just west of Alamogordo, New Mexico. August 21 was a special night at White Sands—Full Moon Night. The park stays open until 11 p.m., and visitors come from near and far to experience the magic of the white sands by moonlight—which was one of the main reasons we were there. The flowers of the Hartweg’s sundrops glow in the moonlight and are very easy to see when the moon is full, by us as well as their hawkmoth pollinators.

After checking in with the National Park Service office, we set out to find Hartweg’s sundrops. The dunes provided the perfect white backdrop to capture hawkmoths visiting the flowers. Usually it’s hard to follow an individual moth at dusk; they become lost in the vegetation unless they’re quite close to you. At White Sands, you could follow an individual hawkmoth easily, from flower to flower, plant to plant—that is, if they showed up.

For a second night, we were out at the golden hour. Everything was beautiful, bathed in the light of the setting sun. We were feeling optimistic. Considering that this was our last chance to capture moths on film, we were prepared to stay as late as necessary. Looking around at everyone, I realized just how lucky I was, how lucky we all were to be there, together, at this incredible place, on what was sure to be an incredible night. Could we also be so lucky as to be graced by the presence of hawkmoths? We had come so far to capture this moment, and I have experienced many nights when conditions seemed ideal for hawkmoths to show up, only to be stood up instead—like the night before, at Yeso Hills.

Before long, the sun had dropped over the horizon and the timing seemed right. I mentioned to Chris that I wouldn’t be surprised if we started to see some hawkmoths. As if on cue, a moth flew right by Chris’s head, close enough for him to hear its papery wings fluttering about—all as the camera was rolling! To say I was excited is an understatement. One moth turned into two…three…six…ten—visiting flowers, drinking nectar, and picking up pollen on their tongues, faces, and bodies, moving it from flower to flower—doing the ever-so-important job of pollination. You see, these plants will not produce fruits or seeds on their own—they require pollen from a different plant to do so, and that pollen has to be transported by a pollinator.

So after much nervous anticipation, the hawkmoths had arrived. And now you can see the full episode and how our adventures fit together into a nice story about desert plants that flower at night and their hawkmoth pollinators!

Many thanks to Chris, Tim, and Paul, for being so incredibly fantastic to work with, and Mike, Norm, Hilda, Helga and Patrick, from whom I learned a great deal about the New Mexico flora and gypsum endemism. Thank you to Sophia Siskel and the Chicago Botanic Garden for providing financial and institutional support. This trip was truly the experience of a lifetime.
