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.

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.

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.

When Ina Vandebroek, Ph.D., started to study how immigrant Caribbean communities use traditional plant-based medicines in their health care, she soon realized that her subjects often did not tell their doctors about the various remedies they are using.

To help bridge this gap, Dr. Vandebroek, the Matthew Calbraith Perry Assistant Curator of Economic Botany and the director of the Caribbean Program at the Institute of Economic Botany of The New York Botanical Garden, has held nearly 50 training sessions for 740 medical students and practicing physicians.

The goal of these sessions is to raise awareness among health-care practitioners about traditional plant-based medicines so they can communicate better with their patients, build trust, and identify potentially harmful drug interactions between mainstream pharmaceuticals and the active chemicals in traditional remedies.

After initially focusing on immigrants from the Dominican Republic, Dr. Vandebroek has now expanded her research project to include Jamaican immigrants. Her research is supported in part by a World of Difference grant from the Cigna Foundation, which announced last week that it was renewing the grant for a second year.

Dr. Vandebroek recently wrote about the importance of understanding immigrant health care practices for “The Doctor’s Tablet,” a blog at Albert Einstein College of Medicine, where Dr. Vandebroek has held several training sessions for its health care professionals. You can read her post here.

New Jersey Transplants “Lichen” Their New Home

Posted in Interesting Plant Stories on October 23, 2015 by Science Talk

Jessica L. Allen is a graduate student in the Commodore Matthew Perry Graduate Studies Program, and James C. Lendemer, Ph.D., is an Assistant Curator in the Institute of Systematic Botany, both at The New York Botanical Garden. Lichens are their primary research interest.

In April, two species of lichens made their way from the Rutgers Field Station in New Jersey to the Thain Family Forest here at The New York Botanical Garden. You might be wondering how they are faring six months later. We took a walk into the forest recently to check in on them.

They’re still alive! A number of them, however, have mysteriously disappeared.

The old man’s beard (Usnea strigosa) hanging on the branches are healthier than those that were attached directly to the trunk of the tree. The reindeer lichen (Cladonia subtenuis) that were nestled deeply into the leaf litter are healthiest, though animals disturbed some of these lichens and they are now fragmented across the ground. About 20 percent of the transplanted lichens are nowhere to be seen. They were likely taken by birds and squirrels living in the forest to be added to their nests.

A Long Way to Go: Protecting and Conserving Endangered Fungi

Posted in Interesting Plant Stories on October 13, 2015 by Naveed Davoodian

Naveed Davoodian is a Ph.D. candidate in the Commodore Matthew Perry Graduate Studies Program at The New York Botanical Garden and the City University of New York. His research is focused on the diversity, evolution, and conservation of fungi.

Despite the many benefits that fungi provide, conservation policies and actions have incorporated these critically important species in very limited ways. On a global scale, fungi lag significantly behind plants and animals in conservation efforts. The situation is, unfortunately, no different in the United States.

To illustrate this point, I examined and evaluated U.S. federal conservation policies that directly list fungal species. This analysis, which focused on the Endangered Species Act of 1973 and the Survey and Manage Standards and Guidelines of the Northwest Forest Plan, was published earlier this year in the journal Biodiversity and Conservation. While both of these frameworks have contributed positively to biodiversity conservation in the U.S., both currently suffer from obstacles hindering protection of fungi and other overlooked organisms.

In my last blog post I examined coffee, the official beverage of NYC movers, shakers, and deal-makers and source of my favorite alkaloid, caffeine. This article is something of a sequel. While the consensus seems to be that a sequel is never as good as the original, I could muster a boatload of rabid Star Wars fans that would argue to the contrary. In any case, my sequel involves a frosty highball of fine aromatic gin, a juicy wedge of lime, and a comfortable seat in the shade—so how bad could it possibly be? The alternate ending is not so pleasurable—it features high fever, chills, profuse sweating, nausea, and a plethora of other equally objectionable symptoms. Intrigued? Confused? Let me elaborate.

Outside of a handful of plant geeks, most folks probably aren’t that familiar with trees of the genus Cinchona (pronounced “sin-cho-nah”). They are native to the tropical Andean region of South America with some species reaching north into Central America or west as far as French Polynesia. It’s a pretty tree by most standards. The big Cinchona pubescens in the Upland Rainforest house of the Conservatory bears large, soft, elliptic green leaves and attractive panicles of rose-pink flowers in spring. But truly—anyone can stand around and look pretty. What makes this tree so fascinating is what it can do.
