Chestnut Chat 35: Friday, April 15, 2022 – Habitat Suitability

Topic:  April’s Chestnut Chat covered Habitat Modeling for American chestnut. Jennifer Santoro, a visiting assistant professor in the Department of Geography and the Environment at Villanova University, and Alec Henderson, a senior at Villanova University with a major in Environmental Science and a minor in Computer Science led this discussion.  Together they described their research for modeling and mapping suitable chestnut habitat in Pennsylvania and showed how analyses like this can be useful for chestnut restoration efforts. Jen and Alec also discussed research to model and map suitable chestnut habitat in Pennsylvania and show how analyses like this can be useful for chestnut restoration efforts.

Chestnut Chat 32: Friday, January 21, 2022 – Evolution of the Genus Castanea

Topic:  Evolution of the genus Castanea, presented by Taylor Perkins, research associate, University of Tennessee at Chattanooga (UTC). Taylor shared a high-level view of evolution and migration of the genus Castanea across the world, starting in China and moving finally into the United States. Taylor has been studying the relationships and divergence of chinkapin and chestnuts in the eastern U.S. for over a decade. Working with Dr. Hill Craddock at UTC, he was recently awarded a TACF external grant to further delve into the mysteries of Ozark chinkapin origin.

Chestnut Chat 30: Friday, November 19, 2021 – Restoration of Pine Savannah Ecosystems

Topic:  Don’t Let Perfection Be the Enemy of Good – Lessons from Longleaf Pine Savanna Restoration. Presenters Zach Prusak (Tall Timbers Research Station), Chris Matson (Florida Park Service), and Walt Thomson and Chaz Oliver (The Nature Conservancy) will look at the Longleaf Pine Savanna restoration process as an analogy for American chestnut restoration. While this is not an apples-to-apples comparison, the Chat will focus on how we can perceive this gigantic undertaking: Are there out-of-the-box perspectives that can be incorporated into the journey towards American chestnut restoration? What roadblocks and bottlenecks were encountered amidst Longleaf Pine Savanna restoration and how were those overcome?

Chestnut Chat 29: Friday, October 15, 2021 – Genomic Selection

Topic: Genomic Sequencing 101 and the Genome of American Chestnut. People often ask, “Have you considered gene editing to enhance disease resistance in American chestnut?” For gene editing to become a possibility we need to know what to edit. TACF Director of Science Jared Westbrook discussed the foundational research being pursued to enable gene editing. Additionally, Nathan Cude, senior scientist at Novozymes North America and project leader in microbial discovery, covered the basics of DNA from its structure to its role in the cell to its sequencing and explains why genome sequences are so important to the modern biologist.
