Top 10: The Best Popular-Science Books of 2016

Posted in Books: Past and Present on December 22, 2016 by Esther Jackson

Esther Jackson is the Public Services Librarian at the New York Botanical Garden’s LuEsther T. Mertz Library, where she manages Reference and Circulation services and oversees the Plant Information Office.


Many exciting science books were published in 2016, including an enormous number of more specialized botanical texts. But of all the excellent titles intended for a general audience, a few stood out in particular for me. Here are my favorite popular-science books of the year.

Botanicum (Welcome to the Museum)Art & Art History

Botanicum (Welcome to the Museum) catches the eye immediately, its cover adorned with botanical illustrations.  Illustrator Katie Scott has breathed contemporary life into her botanical illustrations with an art nouveau-like aesthetic that manages to recall historic botanical illustration styles. Author Kathy Willis has divided the text into “galleries,” titled The first plants; Trees; Palms and cycads; Herbaceous plants; Grasses, cattails, sedges, and rushes; Orchids and bromeliads; and Adapting to environments. This is a beautiful book for casual plant lovers as well as those who are already passionate about botany and botanical art.

A Conversation about Plant Conservation in the Modern Era

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

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


In Defense of PlantsIn the effort to conserve the planet’s biodiversity, plants tend to be overlooked. People spend much more time and money on “charismatic” species of animals. For instance, 100 percent of the world’s known threatened and endangered animals have been assessed by the International Union for the Conservation of Nature, the most important global institution when it comes to evaluating such threats. But only assessed about five percent of plants have been assessed.

It’s a scary state of affairs, especially considering that so-called biodiversity hotspots are defined by their vascular flora.

The New York Botanical Garden is working to improve awareness and understanding about the botanical world. That was one of the topics when Matt Candeias of the blog and podcast “In Defense of Plants” interviewed Dr. Brian Boom who, among his other responsibilities at the Botanical Garden, is the Garden’s Vice President for Conservation Strategy.

Stressed Out: How will Vietnam’s Unique Flat-Leaved Pine Respond to Climate Change?

Posted in Interesting Plant Stories on December 2, 2016 by Stephanie Schmiege

Stephanie Schmiege, a Ph.D. candidate at the Commodore Matthew Perry Graduate Studies Program of The New York Botanical Garden and at the Department of Ecology, Evolution and Environmental Biology of Columbia University, is researching response of conifers to environmental stress under the direction of Drs. Dennis Stevenson and Kevin Griffin.

The Central Highlands of Vietnam are home to the world’s only known flat-leaved pine. Endemic to this area, Pinus krempfii was first discovered by French botanists, who were astounded by its unique leaves and even confused it with species from an entirely different family. Not only is it the only known pine with flat leaves, it is the only pine we know of that successfully survives in dense tropical forests. Scientists think that the flattened leaves may allow Pinus krempfii to absorb more light than most needle-leaved pines, which in turn facilitates its success in the tropics. However, flattened leaves require vulnerable tissues to transport water throughout the leaves. 

This trade-off may leave Pinus krempfii susceptible to changes in climate, particularly drought stress. Climate models for Southeast Asia forecast increasingly long dry periods. How will Pinus krempfii respond to increasing drought stress? Will the unique leaves that have assisted its survival in the tropics prove to be its undoing?

A quicksilver flash diverts your eye from the Bronx River’s frothy flow over the 182nd St. dam at River Park. Was it just the remnants of a potato chip bag slithering downstream?

Look again, and quick! If you’re lucky, you could glimpse an American eel, Anguilla rostrata.

Against unfavorable odds, the American eel has persisted in the urban waterways of New York since the city’s inception—surviving years of industrial pollution, raw sewage dumping, and runoff. In recent years, their populations have entered a precipitous decline, driven in part by long-term effects of the damming of freshwater rivers and streams, which they require as habitat.

What makes this strange and wonderful species—its finely-scaled body coated in a mucous layer that is truly “slippery as an eel”—important?

Charles Zimmerman is Herbarium Collections and Outreach Administrator for the William and Lynda Steere Herbarium at The New York Botanical Garden.


WeDigBio 2016CALLING ALL ENVIRONMENTAL STEWARDS AND CITIZEN SCIENTISTS!

For centuries, biologists have explored and documented the natural world, collecting the billions of specimens now stored in museums, universities, and field stations worldwide. In the past few years, The New York Botanical Garden and other institutions across the globe have made tremendous strides toward unleashing the treasure trove of information stored in these collections for researchers and the general public.

Now, there is a way you can help!

On Saturday, October 22nd, from 10:30 a.m. to 3:30 p.m., The New York Botanical Garden’s William and Lynda Steere Herbarium will partner with Fordham University to host a community-based Natural History Collection Bioblitz as part of WeDigBio 2016, a global four-day volunteering event focused on mobilizing biodiversity data from preserved museum specimens to advance scientific research.

Podcast: Plants as Medicine

Posted in Videos and Lectures on October 14, 2016 by Stevenson Swanson

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


In a new podcast from health insurer Cigna, Ina Vandebroek, Ph.D.—the Matthew Calbraith Perry Assistant Curator of Economic Botany and Caribbean Program Director at The New York Botanical Garden—discusses how she studies the ways in which Caribbean and Latino immigrants in New York use medicinal plants in their health care.

As part of her research, she delves into the traditional knowledge, beliefs, and practices of the Dominican and Jamaican communities and also carries out field research in the Dominican Republic and Jamaica.

Dr. Vandebroek talks about cultural beliefs about specific illnesses and herbal therapies that are recognized in these communities but unfamiliar in mainstream medicine, such as “evil eye.”

Putting her voluminous research to practical use, she has developed training activities with health care professionals to help them understand the traditional beliefs and health care practices of their Latino and Caribbean patients. Her aim is to give doctors and other providers the information and understanding they need to build trusting relationships with their immigrant patients—with fully informed, improved care as the ultimate goal.

You can listen to the 36-minute podcast here.

Dr. Vandebroek’s research is supported in part by a World of Difference grant from Cigna Foundation. 

Once Frozen in Ice, Now Frozen in Time: Artifacts of an Arctic Voyage

Posted in Nuggets from the Archives on September 23, 2016 by Lansing Moore

Sarah Dutton is a project coordinator in the William and Lynda Steere Herbarium, where she is working on a project to digitize the Steere Herbarium’s collection of algae.

Vega in winter quarters

It is 1879, and for months you have been living aboard a creaking wooden steamship trapped in miles of shifting Arctic sea ice. When you venture above deck, the air is icy as you gaze across the polar landscape. Among your companions are several officers, 21 crewmen, six other European scientists of various disciplines, and a few hundred indigenous Chukchi people who live nearby.

Such was the experience of Dr. Frans Reinhold Kjellman, a botanist aboard the SS Vega during the Swedish Vega Expedition. The New York Botanical Garden’s project to digitize the algae collection in the William and Lynda Steere Herbarium has uncovered two algal specimens that Dr. Kjellman collected during this expedition, providing glimpses into a little-known but fascinating story of 19th century science and exploration.

Dr. Frans Reinhold Kjellman

The tale begins with Adolf Erik Nordenskiöld, a Finnish-Swedish scientist and explorer, who had led many successful Arctic expeditions by the time he proposed the Vega Expedition. This time, he planned to circumnavigate the Eurasian continent via the Arctic Ocean and the Bering Strait, or “North East Passage,” to prove that this was a viable route between Europe and the Pacific. The scientists on board the Vega were prepared to gather data about the geography, hydrography, meteorology, and natural history of the Arctic, much of which was still unexplored by Europeans at the time. Kjellman, who had accompanied Nordenskiöld on three previous voyages, was an authority on Arctic algae.

The SS Vega departed Sweden on June 22, 1878. On September 3, the ship began to encounter sea ice. The explorers continued, hugging the coast and searching for a clear way through the increasing ice. However, by the end of September, the ice thickening in front them could no longer be broken by the ship’s hull. They had reached Kolyutschin Bay, the last bay before the Bering Strait, but a belt of ice less than 7 miles wide barred their passage. In his book, The Voyage of the Vega round Asia and Europe, Nordenskiöld expresses regret over time that could have been saved along the journey. He believed that had the ship arrived at Kolyutschin Bay just a few hours earlier, they would have been able to continue. To rub salt in the wound, Nordenskiöld later learned that an American whaler had been anchored only a couple of miles away in open water on the same day the Vega was frozen in.

The Mid-Atlantic Coastal Plain is a close neighbor to some of America’s largest cities, including New York and Philadelphia, but you’d be forgiven if you had never heard of it. This vast, low-lying region extends along the Atlantic coast from southern New Jersey through South Carolina and includes such well-known cities as Charleston and Norfolk and beaches that are enjoyed by millions of visitors every year, such as the Outer Banks of North Carolina.

From Tree to Shining Tree: The Living Network under the Forest

Posted in Interesting Plant Stories on September 7, 2016 by Stevenson Swanson

NYBG fall forest foliage

That old saying about not being able to see the forest for the trees turns out to be more than just a metaphor.  Standing in the middle of a forest, it’s easy to see each tree as an individual, but in reality, the trees are bound together by a living network that proves beneficial not only for the trees—which get the minerals they need to grow to great heights—but also to the network, which gets a steady supply of nutrients from the trees to keep it alive.

What is this network? That’s the mystery that award-winning science journalist Robert Krulwich sets out to answer in a recent episode of public radio’s Radiolab.

His scientific sleuthing brought him to the Thain Family Forest, the 50-acre old-growth forest at The New York Botanical Garden, where he interviewed Curator of Mycology Roy Halling, Ph.D., the Botanical Garden’s expert on all things fungal. That’s a pretty broad hint about the nature of the network, by the way.

As with all Radiolab stories, the result is an adventure in imaginative reporting and storytelling that revels in the wonders of the world around us. Or, in this case, beneath us.

You can hear the episode here.
