Here Today, Gone Forever: Plant extinction now and conservation strategies for tomorrow (Part I) (November 17, 2020)
Plants are essential to all human existence, yet the topic of plant extinction has received little comprehensive study and analysis until recently.
In this two-day, online symposium, a group of international experts in biodiversity, conservation, and extinction presents the state of knowledge, trends, causes, and consequences of the plant extinction crisis. In addition, the presenters discuss strategies for preventing the future decline of biodiversity. Each set of presentations is followed by a Q&A with presenters and the audience.
Thomas E. Lovejoy – “Symposium Welcome and Introduction”
Stuart Pimm – “Plant Extinctions: How many, where, and what can we do to prevent them?”
Maria S. Vorontsova – “Global Knowledge of Plant Extinction: What do we know? And should we trust it?”
Wesley M. Knapp – “Vascular Plant Extinction in the Continental United States and Canada”
Third Annual New York City EcoFlora Conference: Conserving the Rare Plants of New York (November 6, 2020)
Join the foremost practitioners in the conservation of rare plants in New York State and New York City as they present the methods used to monitor and conserve rare species and what the public can do to help.
As we learned during the Second Annual New York City EcoFlora Conference in 2019, The Historical Flora of New York City: Implications for Conservation Action, since 1800 an estimated 500 species of plants have disappeared from the New York City flora. These species can be found outside the City, but are no longer found in the five boroughs. Another 250 species are thought to be rare in the City, known from only one or two populations.
Cycads: From Field Biology to Neurobiology, a Botanical Journey (October 16, 2020)
Dennis Wm. Stevenson
In commemoration of his 40-year scientific career at The New York Botanical Garden, Senior Curator Emeritus Dr. Dennis Wm. Stevenson presents a synopsis of his 50 years of research into varied aspects of cycad biology.
It is a gamut, which follows the many bandwagons of botanical research for the past half-century. His talk includes, but is not limited to, research done in Slice & Dice and Machete Botany (Anatomy and Morphology), Flyspeck Botany (Chromosome Cytology), Blender Botany (Phytochemistry), Spray & Pray Botany (Physiology and Morphogenesis), Pipette Botany (Molecular Systematics and Barcoding), Trekking Botany (Fieldwork), Hard Rock Botany (Paleobotany), and Search for Truth Botany (Phylogenetics). All of these disciplines contribute to and allow for understanding the natural world around us from different aspects and points of view.
NYBG WeDigBio 2020: Virtual Herbarium Tour (October 15, 2020)
Explore ways that scientists study plants during a behind-the-scenes visit to the Steere Herbarium, one of the largest collections of preserved plant specimens documenting plant life around the globe over the past 300 years.
Learn how these collections can be used in conservation work and to study climate change. See wild relatives of crops, invasive species that have taken hold in different regions of the world, and herbarium specimens of plants that are now extinct.
The Brazilian Amazon Under Threat: A Report on the Impacts of Climate Change and Deforestation in the World’s Largest Rain Forest (September 25, 2020)
The Amazon Forest in South America is the largest rain forest on Earth and harbors an estimated 15% of all plant species.
It stabilizes the climate of South America and stores more than 100 trillion tons of carbon, thus helping to mitigate global warming. Despite its biological importance and wealth of ecosystem services, the Amazon Forest faces tremendous threat, including widespread deforestation, unsustainable development, and increasing drought and wildfire. Its biodiversity is still incompletely known, and many large areas within the Amazon remain inaccessible and understudied. Dr. Benjamin Torke will report on his efforts to compile botanical inventories of protected areas in an understudied and threatened part of the Brazilian Amazon, the basin of the Tapajós River, and will discuss some of the challenges that he has encountered along the way. He will also report on concerning trends in climate, wildfire, and deforestation in the region and discuss strategies for avoiding a projected collapse of the ecosystem.
