The Rock Gnome

Posted in Interesting Plant Stories on May 27, 2016 by Jessica Allen

Jessica L. Allen is studying for a Ph.D. as a student in the Commodore Matthew Perry Graduate Studies Program at The New York Botanical Garden. Lichens are her primary research interest.

ForestGnomes exist. They’re quite short and green with black caps. The only place to find them is on rocks in the southern Appalachians, and the best place to find them is in western North Carolina.

The gnome I’m describing is actually a lichen (which are combinations of fungi and algae) known as the rock gnome lichen (Cetradonia linearis). It’s one of two fungal species protected by the Endangered Species Act and a member of one of the largest families of lichens, Cladoniaceae.

The rock gnome was one of four fungal species recently added to the Red List, a list of endangered species all over the world that is maintained by the International Union for the Conservation of Nature. Before these four species were added, only two fungal species were recognized on the Red List. The rock gnome lichen was added to the Red List after a successful meeting at The New York Botanical Garden last summer, during which a group of lichenologists came together to prepare detailed assessments of North American lichens.

World Flora Online New York Botanical GardenAs if assembling a comprehensive, scientifically verified database of more than 350,000 plant species were not a daunting task to begin with, try doing it in only four years. That’s the ambitious goal the scientists working on World Flora Online (WFO) are racing to meet.

When it’s up and running, WFO will provide scientists, conservationists, political leaders, and other policy-makers with information they need to protect one of Earth’s most important resources—its plants.

More than two dozen of the world’s leading plant scientists gathered at The New York Botanical Garden recently to review the progress that has been made on WFO and to plan the way forward so they can meet the goal of completing the database in 2020, which was established in the Convention on Biological Diversity, an international agreement.

As part of a week-long series of meetings at the Botanical Garden, several of the participants spoke about specific aspects of this monumental project during a symposium on Wednesday, April 27, in the Garden’s Ross Hall.

The presentations began with introductory remarks by Barbara M. Thiers, Ph.D., the Garden’s Vice President for Science Administration and the Patricia K. Holmgren Director of the William and Lynda Steere Herbarium. She noted that the Garden is one of four leading botanical institutions that are working together to coordinate the efforts of scientists and institutions around the world to create this first-of-its-kind online resource.

Sex, Lies—and Orchids?

Posted in Interesting Plant Stories on April 15, 2016 by Stevenson Swanson

OrchidOh, those naughty orchids. An insect may think it has found a safe place to lay its eggs or discovered a willing partner for a tryst, but it turns out that nest or member of the opposite sex is really an orchid. Orchids have evolved these deceptive appearances and many other techniques such as alluring aromas and vibrant colors to lure insects to do their bidding, namely to spread their pollen to other orchids so they can produce seeds.

Just in time for the closing weekend of The Orchid Show: Orchidelirium, the public radio program Science Friday has posted a short video on its website that explores the evolutionary adaptations that have allowed some of the most beautiful members of the plant kingdom to flourish. Shot at The New York Botanical Garden and featuring Marc Hachadourian, Director of the Nolen Greenhouses and Curator of Orchids, this video may leave you thinking that we humans are just as susceptible to the allures of orchids as those six-legged pollinators.

NYBG Scientists Help Discover a Promising Anticancer Agent to Fight a Childhood Scourge

Posted in Interesting Plant Stories on March 30, 2016 by Daniel Atha

Daniel Atha is the Conservation Program Manager at The New York Botanical Garden.

A chemical agent found in a member of the snapdragon family (Scrophulariaceae) has shown early promise as a potential treatment for a cancer whose victims are overwhelmingly infants and children.

I recently co-authored a paper describing the potency of a chemical extracted from Armenian figwort (Scrophularia orientalis) in killing malignant cells found in neuroblastoma, a cancer of the nervous system. Neuroblastoma is the most common non-brain solid tumor in children and the most common cancer in infancy (NIH NCI, 2016). Almost half of its victims are children under two years of age.

Living Fossils: A Scientist’s Fascination with Cycads

Posted in Interesting Plant Stories on March 9, 2016 by Stevenson Swanson

Stevenson Swanson is the Science Media Manager at The New York Botanical Garden.

Palms of the World Gallery cycadCycads, an ancient group of cone-producing tropical plants, are sometimes called “living fossils” because they have existed for more than 200 million years–since before the time of the dinosaurs. Yet despite surviving mass extinctions, continental drift, ice ages, and other challenges, cycads are in trouble today.

Some cycads such as the sago palm are popular commerical plants, but in the wild, habitat destruction and poaching are now pushing many species in this group to the brink. The International Union for the Conservation of Nature has said that 53 percent of the approximately 300 species of cycads are imperiled.

One of the world’s leading experts on this intriguing group of plants is Dennis Wm. Stevenson, Ph.D., Vice President for Botanical Research and Cullman Curator at The New York Botanical Garden. Dr. Stevenson’s cycad research has taken him to every continent, including Antarctica, and he has discovered and described many new species.

Recently, Matt Candeias of the blog and podcast “In Defense of Plants” talked to Dr. Stevenson about his decades-long fascination with cycads, which began during his years as a graduate student at the University of California-Davis. You can hear their conversation here.

Flowers in the Gallery: A Melding of Art, Botany, and Politics

Chelsea’s powerhouse Gagosian Gallery is not the most likely place you’d find pressed herbarium specimens.

But that’s exactly what you’ll see there as part of the gallery’s current show by multidisciplinary artist Taryn Simon.

In “Paperwork and the Will of Capital,” Simon recreates and photographs the elaborate centerpieces that sat between powerful men as they signed agreements designed to change the world. Preparing the exhibition, Simon worked with Daniel Atha, NYBG botanist and Conservation Program Manager, and Sheranza Alli, NYBG Senior Museum Preparator and Herbarium Aid, who teach a Plant Collection and Preservation Workshop at the Garden.

Great Big Story: World Flora Online in the Spotlight

Posted in Interesting Plant Stories on December 29, 2015 by Stevenson Swanson

Stevenson Swanson is the Science Media Manager at The New York Botanical Garden.

Enid A. Haupt ConservatoryIt’s a great big story, all right.

CNN’s new online video unit, called Great Big Story, recently reported on The New York Botanical Garden’s work on World Flora Online, a worldwide effort to produce a single, scientifically verified database of information about all of the world’s plant species—an estimated 350,000 of them.

The video captures the activity in the Mounting Room and Digital Imaging Lab of the William and Lynda Steere Herbarium as specimens are carefully glued to acid-free paper and then photographed in ultra-high resolution before they are filed in the Steere Herbarium.

There are also stunning images of rain forest and desert plants in the Botanical Garden’s Enid A. Haupt Conservatory. The variety and beauty of the plants drive home the point made by Dr. Barbara Thiers, the Garden’s Vice President for Science Administration and Director of the Herbarium.

“Plants are endlessly fascinating,” she says in the video. “We have to know what they are and how they differ from one another in order to understand what kind of measures need to be taken to protect them.”

Early Detection, Rapid Response: Applying the Resources of The New York Botanical Garden to an Emerging Invasive Species

Visitors to the LuEsther T. Mertz Library have the chance to see an exhibition centered on an emerging invasive species, Corydalis incisa, or incised fumewort.

This display, on view in the Rare Book Room window, arose from a collaboration between the Mertz Library and the Science Department. In preparation for last month’s Invasive Species Summit, staff brainstormed ways to use the Library’s display space to offer a compelling supplement to the programming of the Summit itself. Rather than displaying items from the Library’s collection illustrating unrelated invasive species, a more powerful exhibition would offer the narrative of one invasive—Corydalis incisaCorydalis incisa is an emerging invasive that Garden staff have studied and monitored for several years.

Daniel Atha, NYBG Conservation Program Manager, first wrote about Corydalis incisa in 2014 here on Science Talk Blog: “A member of the fumitory family, Corydalis incisa … is native to China, Korea, and Japan. It was first discovered growing wild in North America during the 2005 Bronx Park BioBlitz, north of The New York Botanical Garden.”

WeDigBio: Bringing Biological Collections to the World

Posted in Interesting Plant Stories on November 20, 2015 by Science Talk

Mari A. Roberts is a Volunteer Coordinator at The New York Botanical Garden’s William and Lynda Steere Herbarium. Her work focuses on engaging citizen scientists in the digitization of plant specimens.

wedigbioDid you know that you can volunteer on a global initiative right here at The New York Botanical Garden? That’s what happened last month when 15 volunteers participated in the Worldwide Engagement for Digitizing Biocollections (WeDigBio), making information on biodiversity collections—such as pressed plants, pinned insects, and aquatic species in jars—available online.

WeDigBio was a one-of-a-kind event engaging hundreds of volunteers to transcribe specimens at more than 30 institutions via multiple transcription platforms (DigiVolHebaria @ HomeLes HerbonautesNotes from NatureSmithsonian Institution’s Transcription Center and Symbiota). One goal of WeDigBio was to increase awareness of the importance of biodiversity collections and of making them easily available online to researchers worldwide. Thanks to WeDigBio volunteers at The New York Botanical Garden, The National Museum of Natural History, Australian Museum, Florida State University and dozens of other institutions, data on more than 31,000 biological specimens will be available for researchers, graduate students and even citizen scientists!

Biodiversity collections held in universities, natural history museums and herbaria are physical representations of our planet’s life forms and biological processes. Plant specimens are collected in the field and then stored in a herbarium, where they can remain for hundreds of years. However, collections are not easily accessible to the general public, nor are there digital representations of every specimen.

“Never has it been more important for museums to open their specimen cabinet doors to the public,” says Austin Mast, a WeDigBio organizer and Associate Professor of Biological Science at Florida State University. “Everyone should have the chance to see the rich textures of life on Earth in these collections. Public participation of this sort helps science bring those rich textures into sharper focus.”

The William and Lynda Steere Herbarium at the Botanical Garden is one of 3,400 herbaria in the world and holds 7.8 million specimens that are used by Garden scientists and visiting researchers. To digitize our collections—that is, cataloging them, imaging specimens, and transcribing specimen information—staff and volunteers work on multi-institutional grant-funded projects to target specific areas of the Steere Herbarium’s collections.

For WeDigBio, Garden volunteers captured information about the historical who, what, when, and where of 500 specimens of bryophytes (mosses and their relatives). Bryophytes are model organisms for documenting environmental change because they take up atmospheric nutrients in their environment. By studying these sensitive indicators in historic and recent collections, scientists can address research questions concerning the change in species distributions after man-made environmental events such as climate change, air pollution, and habitat destruction.


Interested in volunteering? You don’t have to wait until WeDigBio 2016! There are opportunities in the Steere Herbarium year round. Help us discover vital information in our rich collection of plant specimens and contribute to our cause of preserving biodiversity.
