In August, renowned botanist Reinaldo Aguilar was honored for his ongoing inventory of the plants of the Osa Peninsula, which juts into the Pacific Ocean in southwestern Costa Rica near the Panama
border. In a ceremony at Corcovado National Park on the peninsula, Costa Rican President Luis Guillermo Solís presented Reinaldo with an award and pointed out how important botanical inventories are for selecting and managing biological preserves on the Osa, a region of high biodiversity.

Reinaldo began documenting plant diversity on the Osa in 1991 and continues to explore for new and interesting plants. Since 2008, Reinaldo has been collaborating with the William and Lynda Steere Herbarium of The New York Botanical Garden and is the lead author of the Vascular Plants of the Osa Peninsula.

The New York Botanical Garden and Cuba’s National Botanical Garden (Jardín Botánico Nacional, or JBN) have a history of collaboration that spans no less than five decades on numerous specific plant research and conservation initiatives. Science Talk has chronicled some of the more recent ones here, here, and here.

Earlier this month, Nora Monterrey, JBN’s General Director, and Alejandro Palmarola, Head of Conservation Program at JBN, visited NYBG to launch an exciting new era for collaboration between our two institutions. The discussions about this renewed commitment for collaboration began in Havana in July 2015, when one of us (Brian) went to Cuba to meet Nora as the new General Director of JBN and to discuss how our institutions could best join forces on cutting-edge science or conservation projects.

However, in a visionary move, Nora Monterrey proposed to take our collaboration to the next level. Instead of a specific agreement for a specific collaborative project, she envisioned establishing a wide-reaching umbrella agreement, spanning multiple years. This approach, which is laid out in a Memorandum of Understanding (MOU), will promote all sorts of collaborative initiatives between our institutions–not only science and conservation but also other programmatic areas such as education, horticulture, and exhibitions, as well as support areas, such as marketing, outreach, and sustainable tourism.

Representing a major advance in understanding and conserving the plant life of one of the world’s greatest biodiversity hotspots, an international team of scientists—including four researchers from The New York Botanical Garden—has created the first scientifically vetted list of known plant species in the Amazon Basin.

Based on documented plant specimens held in research collections worldwide and verified by specialists in tropical plants, the team cataloged 14,003 species of seed plants in the Amazon Basin, including 6,727 species of trees. Their research paper, which has just been published in the Proceedings of the National Academy of Sciences (PNAS), is available here.

Until now, the number of plant species that live in the Amazon Basin has been hotly debated, with estimates ranging from the tens to the hundreds of thousands. But those numbers have been based on ecological models or unverified species lists. This study assembles comprehensive species information based on plant specimens identified by specialists.

The William and Lynda Steere Herbarium is especially proud to report the successful completion of Phase I of our largest citizen-supported initiative to date, which makes much historic data for vascular plants of northeastern North America freely available online for the first time. Following the October 2016 launch of this WeDigBio worldwide citizen science event, over 190 online participants contributed a total of 7,177 transcriptions, providing new digital records for 300 species from familiar plant families including sunflowers (Asteraceae), blueberries (Ericaceae), oaks (Fagacae) and grasses (Poaceae).

Through an ongoing partnership with Notes from Nature, virtual volunteering for Steere Herbarium projects has quickly become the most accessible platform for citizen engagement in scientific research at The New York Botanical Garden. Using any computer with access to the Internet, curious and enthusiastic volunteers can view digital images of historic preserved plant specimens in our collection. Through self-guided training (and a little practice), participants interpret and transcribe the often handwritten information on a specimen sheet about the context in which a plant was found in the wild, including the name of the scientist who collected the sample, the geographic location, and the date of collection.

Under-explored and Under Threat: Documenting Plant Life along Brazil’s Tapajós River

Posted in Interesting Plant Stories on August 1, 2017 by Julia Beros

Julia Beros has worked or interned at The New York Botanical Garden for more than two years, including at the Pfizer Plant Research Laboratory and the Ruth Rea Howell Family Garden. In May, she graduated from Sarah Lawrence College.

It’s hardly a secret that the Amazon rain forest, the largest expanse of tropical rain forest on earth, houses great biodiversity and that environmental degradation from climate change and human enterprise is a massive and looming threat throughout the region. The most critically threatened areas also happen to be the least studied and inventoried, but they are estimated to have the highest biodiversity within the Amazon rain forest. NYBG scientist Benjamin Torke, Ph.D., is working to fill in the gaps in our understanding of the rich plant life in one such area in the state of Pará in the southeastern part of the Brazilian Amazon.

Recently, environmental degradation has threatened the potential for capturing and sharing this knowledge. In the southeastern regions of the Amazon, many of the detrimental effects of climate change are heightened by expanding human development. Ranching, logging, soy bean farming, mining, and settlement all contribute to the loss of natural habitat. The construction of a highway that bifurcates the forest has simultaneously created isolated regions of biodiversity and increased the rate of forest degradation. The potential loss of biodiversity is almost visible from satellite images in which beige hatched lines scratch across the dense green rain forest.

Photo of a shipping labelWhen your local library doesn’t have a copy of that latest best-seller that you’ve been dying to read, it can usually request the title from another library. Something very similar happens when plant researchers are looking for preserved specimens in their field of study: they can request loans of these invaluable resources from research repositories across the globe.

NYBG’s William and Lynda Steere Herbarium sends an average of 20,000 specimens out on loan every year. Even now, as millions of ultra high-resolution digital images of plant specimens are becoming readily available online in The New York Botanical Garden’s C. V. Starr Virtual Herbarium, there are still many times when nothing short of the physical specimen will do.

Ontogeny recapitulates phylogeny doesn’t exactly flow off the tongue unless you are familiar with scientific terminology. However, what appears to be a somewhat intimidating phrase is actually marvelously succinct and elegant.

Ontogeny is “the development or course of development, especially of an individual organism.” This could refer to the development of a plant from embryo to seed to seedling to mature, reproductive plant. Or it could refer to an animal growing from an embryo into an infant and then into an adult. 

Phylogeny is “the evolutionary history of a genetically related group of organisms, as distinguished from the development of the individual organism.” Sometimes these relationships are illustrated as trees of information, with groups of closely related organisms called clades. Studying and depicting shared evolutionary history is known as cladistics. Have you seen Darwin’s tree of life

If so, then you understand the basic idea of phylogeny. It’s all about the study of relationships.

Recapitulate means “to repeat the principal stages or phases.” For most, this is perhaps the most recognizable word of the trio. Actually, it is the namesake of recapitulation theory.

Capt Cook SpecimenPress. Dry. Mount.

That’s the basic process for turning a plant into a research specimen that will last indefinitely, and it’s stayed the same for hundreds of years for a good reason: It works.

As proof, here’s a member of the daisy family that botanists Joseph Banks and Daniel Solander clipped in January 1769 in Tierra del Fuego, at the southern tip of South America. They were part of the scientific team aboard the HMS Endeavour on Captain James Cook’s first voyage around the world. This 248-year-old specimen, still holding onto its leaves and retaining most of its color, is now part of the collection of 7.8 million preserved plants in NYBG’s William and Lynda Steere Herbarium, the second largest in the world.

A Conversation about Plant Conservation in the Modern Era

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

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 unique flattened leaf morphology of Pinus krempfii.

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?
