Daniel Zuleta is a postdoctoral fellow working on tropical forest mortality with ForestGEO and Next-Generation Ecosystem Experiments–Tropics (NGEE–Tropics). His research has focused on understanding the spatial variation in drought-induced tree mortality and biomass dynamics, as well as assessing the interactions between the species’ drought tolerances and their spatial distributions in Amazon forests. As a postdoctoral fellow, Zuleta aims to understand the mechanisms driving tropical forest mortality in order to develop mortality models that can be included in the Functionally Assembled Terrestrial Ecosystem Simulator (FATES) model and improve predictions of forest response to environmental changes. He will use long-term forest dynamics data from ForestGEO sites along with annual mortality censuses established by Gabriel Arellano to explore tree death modes and implications on stand carbon dynamics. He will additionally collect data on plant stress attributes and the response of trees to extreme climatic events to infer the physiological mechanisms of tree death. Zuleta is based at the ForestGEO headquarters at the Smithsonian National Museum of Natural History in Washington, DC.

Retiring from the U.S. Department of Agriculture’s Agricultural Research Service in Beltsville, Maryland after more than 30 years, John H. Wiersema will be continuing his taxonomic and nomenclatural work at the National Museum of Natural History as a Research Associate in the Department of Botany, a position he has held since 2014. Previously he was a taxonomist for the USDA’s national germplasm system’s GRIN database. This position provided the opportunity to develop GRIN Taxonomy into an extensive and exhaustive taxonomic resource on economic plants important to global agriculture. Through this work Wiersema gained global standing as a specialist in plant nomenclature, and now has direct editorial involvement with both the botanical and cultivated plant codes of international nomenclature and the international journal Taxon. Wiersema is also well known as a specialist on the taxonomy of the water-lily family, especially the genus Nymphaea, is responsible for the discovery and description of several new species, and has participated in over 30 scientific publications on the group. He expects to pursue both of these interests here in the Botany Department.

I Know What You Did Last Summer: Reflections from Botany Interns

From Plant Press, Vol. 20, No. 4, October 2017.

The Department of Botany is happy to host high school, undergraduate, and post-graduate student interns throughout the year. Internship activities peak during the summer, and 2017 was no exception. Below are a number of reflections from both interns and their supervisors highlighting the intern summer experience in Botany.

Intern Clara Cebral-Marani (third from the right) joins Botany staff to view the partial eclipse on the National Mall in Washington DC on August 21, 2017.

Clara Cebral-Marani, rising senior at a Virginia high school:
This past summer, I was a summer high school intern in the Botany Department and had the privilege to have Erika Gardner as my mentor. The internship was an incredible experience for me. I assisted Gardner in multiple tasks, such as care and handling of specimens, transaction entry using KE EMu database, and preparation of large lots of specimens to be shipped to herbaria worldwide. I attended several collection tours and two useful lectures. One of the lectures was about how to apply for a Smithsonian job, which will be useful in the future. I was fortunate to work with a fun group, and was able to enjoy the Great American Solar Eclipse with them.

Colleen Murdock

Colleen Murdock, recent graduate of Trinity College:
It was such a pleasure working with CTFS-ForestGEO this summer. I learned so much about their extensive global reach of 65 research sites and hundreds of scientists working to understand the dynamics of the Earth’s forests. I enjoyed contributing to their wide variety of projects, including organizing and adding content to their new website and helping chart and analyze geographic data. Thank you so much for a wonderful learning experience. I’m moving on to an internship with Smithsonian’s Center for Learning and Digital Access this fall, so I hope to stay involved with ForestGEO in the future. 

 

Libby O’Brien, undergraduate student at Villanova University:

Elizabeth O'Brian (intern, second from left) and her advisors (L to R), Vicki Funk, Robert (Bort) Edwards, and Aleks Radosavljevic.

I was fortunate enough to spend this past summer in the Botany Department working with Vicki Funk, Bort Edwards, and Aleksandar Radosavljevic as a part of the Natural History Research Experience (NHRE) program. Over the course of 10 weeks, I joined the team investigating the diversity of the Guiana Shield of northern South America. I analyzed patterns of richness and diversity from both genetic and spatial data. It was a summer of firsts: my first research experience and my first encounter with genetic data. I learned how to navigate the Metro system in Washington, D.C. as well as how to manipulate spatial data in programs like BioDiverse. It was a summer of re-strategizing what to do with so many data points and remembering to write everything down. I am grateful for all of the guidance and mentorship I’ve received from my mentors, as well as their willingness to keep me in the loop for the continuation of this project. I look forward to furthering this research with the wonderful group of people I met in Botany.

Katherine Rudebusch

Alice Tangerini hosted intern Katherine Rudebusch, who was a recent graduate of the University of California at Monterey Bay’s Scientific Illustration Program. Rudebusch scanned dozens of illustrations for uploading to the Botanical Art Collection in EMu’s multimedia site. Many of these required extensive manipulation to remove discoloration from the backgrounds, usually due to long storage in acidic environments. She also rehoused these illustrations in archival protective sleeves and folders. Rudebusch visited several museums on the National Mall during her stay and joined Tangerini at Hirschhorn Museum evening art programs. On her last week, Rudebusch started work on an illustration of a new species of Fabaceae from the Amazon for researcher Aleksandar Radosavljevic.

In May, Pedro Jiménez-Mejías joined the Department of Botany of the National Museum of Natural History as a post-doctoral fellow. He is working under the supervision of Laurence Dorr and Jun Wen in the evolution and systematics of the mainly boreo-temperate genus Carex in the Neotropics. Little attention has been given to the mode and tempo of evolution of herbaceous temperate elements in the Neotropics, even though they constitute an important amount of the biomass in cold-adapted not-tree dominated communities, such as the Patagonian steppes and the Andean punas and páramos. Jiménez-Mejías received his Ph.D. at the Universidad Pablo de Olavide of Seville, Spain, where he studied the systematics and evolution of two Carex groups with especially problematic taxonomy. He has conducted post-doctoral studies in the Real Jardín Botánico (Madrid, Spain), Washington State University (Pullman, Washington), and the New York Botanical Garden (Bronx, New York). His research also includes evolution and systematics of Resedaceae and Boraginaceae, and genetic studies in endangered species.

To help scientists get the most out of their data, the Smithsonian has hired a new IT specialist in August, Mauro Lepore. Working with the Center for Tropical Forest Science and Forest Global Earth Observations (CTFS-ForestGEO), Lepore is writing and maintaining a collection of small computer programs that help forest ecologists analyze data of over six million trees. Lepore joined the Smithsonian in 2016 as a research fellow at the Smithsonian Tropical Research Institute. He researched how coral reefs in Bocas del Toro, Panama, have changed over the past 7,000 years in response to human impacts. The ideas he developed led to the paper, "Look to the past for an optimistic future," which was recently published in Conservation Biology (O'Dea et al. 2017). Lepore earned a Ph.D. in Ecology in 2015 from the University of Queensland, Australia, and graduated in marine biology in 2008 from the University of Buenos Aires, Argentina.

Winter Interns Contribute to Botany

From Plant Press, Vol. 20, No. 2, April 2017.

The resources available within the National Museum of Natural History, including staff, herbarium specimens, living greenhouse specimens, and a molecular lab, make the Department of Botany an attractive place for students to further their training as young botanists. Internships in Botany are aimed at actively engaging students, providing hands-on education and training in research, collections management and even administration, benefiting both the intern and the Department. Internships have an element of educational training built into the appointment and this training complements the education and career goals of the intern. Botany was fortunate to host several interns this past winter, and we got the chance to hear from a few of them here.

Sarah Brown, an undergraduate from Tarleton State University, was a Collection Management Intern from December 5, 2016 to January 27, 2017. During her internship, Brown assisted the core Collection Management Unit and learned about the care and maintenance of a large collection. She diligently worked on processing incoming Seeds of Success specimens, as well as incoming exchange/gifts, and loans. Brown also helped package, transport and reintegrate our Cladonia lichen collection from our off-site facility to our main collection. Brown tackled the challenging task of filing specimens, collected by Lt. Charles Wilkes from the 1800s, back into the main collection. Brown was enthusiastically engaged in every activity and eager to learn as much as possible about the daily functions of the collection. The information that Brown gathered during her internship will be applied towards the herbarium at her university. In April, Brown will be presenting a poster about the Tarleton Herbarium at the 64^th annual meeting of the Southwestern Association of Naturalists (SWAN) in association with the Texas Oklahoma Regional Consortium of Herbaria (TORCH) 10^th annual meeting.

Yash Kalburgi, an undergraduate at Northern Virginia Community College, has been working with Jun Wen and Liz Zimmer since the fall of 2016. He has been conducting bioinformatics research (genome skimming) on Next Generation Sequencing data for the grape genus, Vitis. In addition to extracting whole plastome sequences from the data, he will be assisting in producing phylogenies from the aligned sequences. Kalburgi will be transferring to a four year college in August 2017.

Elena Meyer, a student from Northern Virginia Community College, returned as an intern from January 9 to February 3, 2017. Meyer first interned in the Department of Botany during the summer of 2013. After her initial internship, she undertook a research project with former staff member Elaine Haug to conduct a floral survey of Occoquan Bay National Wildlife Refuge in Woodbridge, Virginia, with the dual goals of generating a species list and documenting the changes that had occurred under U.S. Fish and Wildlife Service management of the property in the 20-year period since an earlier survey was conducted. The objectives for her current internship was to integrate both her collections from 2014-15 and Haug’s collections from 1991-98 into the EMu database system and to prepare these specimens properly for submission for mounting, as well as selecting sets for possible donation. The specimens Meyer processed and submitted for mounting or donation came from 420 distinct collections of plants, the majority of which were collected with duplicates, for a total of 851 plant specimens. These yielded a set for donation to the U.S. National Herbarium of around 400 pressed plant specimens, a set of duplicates numbering around 200 specimens, and a third set of 200 extra specimens. These plants represent 82 families and 269 species. At least five species are potential county records for Prince William County.

As an undergraduate at the University of Vermont, Jacob Suissa studied plant biology, conducting various research projects ranging from plant physiology to fungal taxonomy. He found a passion for plant systematics and phylogenetics during a tropical plant systematics field course in Costa Rica. He continued his studies in plant systematics during a semester at the University of Hawai’i Manoa. His current research includes elucidating the evolutionary histories in various plant lineages using a phylogenetic framework. Presently, Suissa is working on two projects: using high-throughput (NextGen) sequencing to resolve the phylogeny in a clade of North American heterosporous aquatic lycophytes (Isoëtes); and utilizing new microfluidic technology to analyze a large number of taxa using 276 loci in the Sunflower family (Asteraceae). Starting in late January, Suissa began conducting research on these projects during an internship in the Smithsonian’s Department of Botany under the mentorship of Liz Zimmer. After he concludes his internship at the end of July, he will begin his doctoral studies at Harvard University under William (Ned) Friedman.

Alison Taylor, a student from American University, held a Collections Management internship from October 11 to December 14, 2016. Mentored by Melinda Peters, she worked with staff to acquire, catalog, repair, and loan out specimens. Memorable activities included determining how to carve out foam to secure a specimen of the largest seed in the world, Coco de Mer, Lodoicea maldivica. Taylor also learned that mounting and repairing specimens requires, as she says, “an eye for placement, delicate hands for strapping between tiny leaves, and patience for the whole process.”
