Since his death on August 30, Dr. Oliver Sacks has been described as a latter-day Renaissance man who took a learned delight in many things—neurology, certainly, but also minerals, squids, and other cephalopods such as cuttlefish, and, most definitely, plants.

Dr. Sacks, who was a Board Member of The New York Botanical Garden and a 2011 recipient of the Botanical Garden’s Gold Medal, was especially fascinated with cycads and ferns, and the Garden scientists who specialize in those plants were among those at the Garden who knew him well.

Cycad expert Dennis Stevenson, Ph.D., the Garden’s Vice President for Botanical Research and Cullman Curator, recalled that Dr. Sacks, who for many years paid regular Wednesday visits to the Garden, enjoyed bringing together people from the various fields that appealed to his eclectic nature so they could learn from each other. Botanists learned about cephalopods from marine biologists; geologists learned about plant science from botanists.

“Oliver was always in a most subtle way teaching all of us about the world around us,” Dr. Stevenson said.

Booked Up: A Conversation About a New Guide to an Overlooked Group of Organisms

In this video, two lichenologists sit down to talk about—what else?—lichens. Or rather, a new book about lichens from the NYBG Press, Common Lichens of Northeastern North America.

This field guide “was written for the average person to learn about lichens,” co-author Troy McMullin, Ph.D., tells James Lendemer, Ph.D., Assistant Curator in the Institute of Systematic Botany at The New York Botanical Garden. “It was written in non-technical language,” he adds, noting that the book is richly illustrated with photos of all the lichen species covered in the text.

Lichens, composite organisms made up of a fungus and an alga or other photosynthesizing partner, play important roles in ecosystems and are sensitive indicators of environmental quality. And they can be quite beautiful. They have not gotten the respect or attention they deserve, according to Dr. McMullin, and one sign of that neglect is the fact that Common Lichens is the first book of its kind for lichens.

“There hasn’t been a field guide like this,” Dr. McMullin says. “If you wanted a field guide to the birds, you go to a bookstore and there’s all kinds of them, and there’s ones for mushrooms, for trees and insects, but you never see any for lichens.”

Until now. To order Common Lichens of Northeastern North America, ($39, spiral-bound hardcover), go to the NYBG Press or order from Shop in the Garden.

Here Comes The Sun Science Club: Sunny Thoughts from an NYBG Botanist

What does the sun do? That question was posed recently by Science Friday, the incomparable science news program that airs on public radio stations nationwide. To kick off its latest Science Club education activity, the program asked a number of scientists and solar experts for their thoughts about why the sun matters.

As you might imagine, how you think about the sun depends largely on what you do. Ernest Moniz, the U. S. Secretary of Energy, talked about the sun as a source of energy. A psychiatrist talked about the sun’s influence on our mood.

What about a botanist? The program asked Barbara A. Ambrose, Ph.D., who is Cullman Associate Curator for Plant Genomics at The New York Botanical Garden, to ponder the role of the sun in the world of plants. Here’s her thought-provoking answer:

What does the sun do?

The sun provides energy. Plants transform the sun’s energy into stored chemical energy during photosynthesis. This is an amazing process in which plants take carbon dioxide, water, and the sun’s photons and produce carbohydrates and oxygen. These carbohydrates are the stored chemical energy that allows plants to grow and develop into the food we eat and the flowers we enjoy. Plants have evolved for hundreds of millions of years to harness the energy of the sun efficiently and effectively, something we humans have yet to perfect. What’s really cool is that a byproduct of this reaction is oxygen–the air we need to breathe.

You can read the responses of other experts, as well as hear Dr. Ambrose read her explanation, at the Science Friday site here. You can also share your own thoughts on that page’s comments section or in our comments box.

And if you talk about this with your friends, just remember: the oxygen you’re using to speak came from a sunbeam striking a leaf.

Learning About Lichens: A New Guide to this Important but Overlooked Group From NYBG Press

Common Lichens of Northeastern North America from NYBG PressLichens, those often colorful and sometimes exotic-looking organisms found growing on rocks, soil, and the bark of trees, have not gotten the respect they deserve, but a new book from The New York Botanical Garden Press may help change that.

Designed to be a user-friendly reference for non-specialists, Common Lichens of Northeastern North America is a light and easy-to-use field guide that covers the rich lichen flora of northeastern North America. Amateur naturalists, nature interpreters, forestry workers, land surveyors, researchers, and anyone who is interested in learning more about lichens will benefit from this book.

What are lichens, and why are they important?

Straddling the boundary between plants and fungi, lichens are composite organisms formed by the combination of a fungus and a plant-like component—usually an alga or a type of bacteria that contains chlorophyll. They are important to the full functioning of an ecosystem, and their presence or absence is an indicator of the health of that ecosystem.

Roots: Where The Garden’s Founder Found His Love of Plants

Nathaniel Lord Britton, the botanist who founded The New York Botanical Garden with his wife, Elizabeth, is so closely associated with this institution in the Bronx that it can come as a surprise to learn that he was a native son of the New York City borough that is most distant from here—Staten Island.

SILive, the Web site of the Staten Island Advance, provided a reminder of Britton’s roots in a recent piece that summarized the eminent botanist’s life and accomplishments.

Born in the New Dorp section of Staten Island in 1859, young Britton developed an interest in botany while growing up in what was then a bucolic setting. The Brittons were a long-established family there: an earlier Nathaniel Britton—whose wife’s name was, coincidentally, also Elizabeth—bought a fieldstone cottage in New Dorp in 1695.

Nathaniel Lord Britton historic Richmondtown Staten Island cottageEventually, Nathaniel Lord Britton and Elizabeth Knight Britton inherited the house, which they owned until 1915, when they deeded it to the Staten Island Institute of Arts and Sciences. It was moved in the 1960s to Historic Richmond Town, a historic town and farm museum, where it remains to this day. Although the Britton Cottage is currently closed to the public, the museum has completed a structure report and hopes to receive city funding to restore it.

By 1915, of course, the Botanical Garden was more than two decades old, leading one to wonder whether the Brittons regularly commuted to the Garden from Staten Island. But no: according to the Garden’s archivist, Stephen Sinon, they occupied the cottage only occasionally, living primarily in a residence on Decatur Avenue in the Bedford Park section of the Bronx, close to the Garden.

Still, the Brittons eventually returned to Staten Island. Dying within a few months of each other in 1934, they are buried in the Moravian Cemetery there.

Ginkgo biloba 'Pendula'
Ginkgo biloba ‘Pendula’

The label on that herbal supplement may say it’s Ginkgo biloba, but given the loose regulation of this multi-billion-dollar industry, how can a consumer be sure that that is what it really contains?

That question prompted the New York Attorney General’s office to investigate the ingredients in some popular herbal supplements using a technology that examines the DNA of the ingredients to determine what they are. The investigation’s disturbing findings—four out of five of the products tested did not contain any of the herbs on their labels—led New York Attorney General Eric Schneiderman to order Target, Walgreens, Walmart, and GNC to stop selling their house brands of the supplements.

Using similar DNA “barcoding” technology, New York Botanical Garden scientists have been studying the same question for years, as Dennis Wm. Stevenson, Ph.D., Cullman Curator and Vice President for Botanical Research, pointed out in a letter to the editor that ran in the February 10 edition of The New York Times.

The New York Botanical Garden recently welcomed our distinguished former head of scientific research, Sir Ghillean Prance, one of the most important explorers of the Amazonian rain forest in modern times, who was back for an all-too-brief visit.

Sir Ghillean, who spent 25 years at the Botanical Garden before leaving in 1988 to become the Director of the Royal Botanic Gardens, Kew, was here to celebrate the publication of his new book, That Glorious Forest: Exploring the Plants and Their Indigenous Uses in Amazonia, published by The New York Botanical Garden Press.

In a lifetime devoted to the study and conservation of tropical plants, Sir Ghillean has participated in 39 expeditions to the Amazon, beginning with a 1963 trip to Suriname as a young Garden researcher, which he describes in That Glorious Forest.

From the Field: A Botany Lesson in Vanuatu

Posted in From the Field on December 11, 2014 by Stevenson Swanson

VanuatuOf all the far-flung places that scientists from The New York Botanical Garden explore, one of the farthest in terms of distance and culture is Vanuatu, an island nation in the South Pacific with a population of about 225,000 people spread over 65 islands and speaking more than 113 indigenous languages.

With its remote location, Vanuatu is home to many plant species that are found only there, making it a treasure trove of biodiversity and an important source of materials for biologists to study. The residents rely on native plants for food, fuel, medicine, and more, but unlike some better-known Pacific islands, Vanuatu’s plant life and the traditional knowledge about how to use those plants have not been adequately studied.

One of the most important projects underway at The New York Botanical Garden is the ongoing effort to make the preserved plant specimens in the William and Lynda Steere Herbarium available online. That means more than just taking high-resolution digital images of the plants. It also entails entering all of the information about the specimens, such as where they were collected, when, and by whom, into a searchable database.

Of the 7.4 million specimens now in the Steere Herbarium—the largest in the Western Hemisphere and one of the four largest in the world—Botanical Garden science staff have already digitized more than 2.3 million of them.

Why is this a big deal? Well, as more specimens become available online at the Steere Herbarium and elsewhere, plant scientists and other researchers will be able to compile massive amounts of data about Earth’s plant life for the first time.

The Huffington Post has published a piece by Dr. Barbara Thiers, the Garden’s Vice President for Science Adminstration and the Patricia K. Holmgren Director of the Steere Herbarium, in which she talks about one very important use for this newly available data: gaining a better understanding of the potential impact of climate change on ecosystems.

Internships may seem like a summer-only opportunity to gain exposure to a field and make a contribution to a project, but that’s not the case at The New York Botanical Garden’s Science Division. We have interns here during all four seasons, performing important work and learning plant science firsthand from our researchers.

NYBG science internships are such a great opportunity that the program has been cited as one of New York City’s coolest internship programs.

One of our volunteer summer interns, Chelsea Fowler, a biology student at the University of Tampa, wrote about her recent experience working in the Garden’s William and Lynda Steere Herbarium on a project that is part of the effort to digitize the Steere Herbarium’s 7.4 million preserved plant specimens. This post is from the iDigBio Web site, a national resource for information about digitized natural history collections.
