Ep. 386 - Rethinking Black Walnut Allelopathy

September 11, 2022

"Don't garden under a black walnut!" If you garden in eastern North America, you may have heard some form of this advice at one point or another. Indeed, Juglans nigra has a negative reputation for being allelopathic or producing compounds that hurt neighboring plants. However, is this reputation warranted or is it a case of unscientific propaganda? Bill Michalek of The Field Guides Podcast joins us for a discussion about the science of black walnut allelopathy and what he reveals may not be the clear-cut story you were told.

Ep. 301 - Oaks in Trouble

January 24, 2021

Oaks (genus Quercus) are among the most culturally and ecologically important trees wherever they are native, which is what makes the next sentence so alarmingly depressing. The IUCN currently estimates that nearly 41% of all oak species are of conservation concern. From all out habitat destruction to invasive pests and diseases, there seems to be no end to the threats oaks face. But that doesn't mean people aren't trying to do something about it. In this episode, I sit down with Director of Global Tree Conservation at The Morton Arboretum, Dr. Murphy Westwood to talk about the Global Conservation Consortium for Oak. Because acorns don't lend well to seed banking efforts, the Global Conservation Consortium for Oak is developing numerous avenues to conserve and restore oak species around the world. Join us for a hopeful discussion about the problems oaks face and some of the solutions needed to save them. This podcast was produced in part by Jan, Jerome, Brian, Melody, Azomonas, Ellie, University Greens, Cynthia, John, Ashley, Peter, Cathrine, Melvin, OrangeJulian, Porter, Grif, Jules, Joan, Les, Marabeth, Ali, Margaret, Southside Plants, Robert, Keiko, Bryce, Brittany, Helen, Amanda, Mikey, Rhiannon, Michelle, Kate, German, Joerg, Alejandra, Cathy, Jordan, Judy, Steve, Kae, Carole, Mr. Keith Santner, Dana, Chloe, Aaron, Sara, Kenned, Vaibhav, Kendall, Christina, Brett, Jocelyn, Kathleen, Ethan, Kaylee, Runaway Goldfish, Ryan, Donica, Chris, Shamora, Alana, Laura, Alice, Sarah, Rachel, Joanna, Griff, Philip, Paul, Matthew, Clark, Bobby, Kate, Steven, Brittney, McMansion Hell, Joey, Catherine, Brandon, Hall, Vegreville Creek and Wetlands Fund, Kevin, Oliver, John, Johansson, Christina, Jared, Hannah, Katy Pye, Brandon, Gwen, Carly, Stephen, Botanical Tours, Moonwort Studios, Liba, Mohsin Kazmi Takes Pictures, doeg, Clifton, Stephanie, Benjamin, Eli, Rachael, Plant By Design, Philip, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Mark, Rens, Bendix, Irene, Holly, Caitlin, Manuel, Jennifer, Sara, and Margie.

Ep. 284 - Trees in a Changing Climate

September 27, 2020

Climates have always changed but thanks to human activity it is happening at an ever-increasing rate. For sessile organisms like trees, this often means either adapting in place or risk going extinct. However predicting the outcomes of climate change on life is extremely challenging and differs depending on what kinds of plants you're looking at and where you are studying them. This is where people like my guest come in. Angie Patterson is a PhD student at Columbia University and she is studying how climate change is affecting trees like the red oak (Quercus rubra) that are important components of the forests in which they grow. Angie's research bridges the gap between the molecular scale and the global climate scale in order to help better understand and predict the future of these trees. Angie is also an educator, teaching everyone from children to the elderly about her work and how climate is going to affect the ecosystems upon which all life relies. This podcast was produced in part by Robert, Keiko, Bryce, Brittany, Helen, Amanda, Mikey, Rhiannon, Michelle, Kate, German, Joerg, Alejandra, Cathy, Jordan, Judy, Steve, Kae, Carole, Mr. Keith Santner, Dana, Chloe, Aaron, Sara, Kenned, Vaibhav, Kendall, Christina, Brett, Jocelyn, Kathleen, Ethan, Kaylee, Runaway Goldfish, Ryan, Donica, Chris, Shamora, Alana, Laura, Alice, Sarah, Rachel, Joanna, Griff, Philip, Paul, Matthew, Clark, Bobby, Kate, Steven, Brittney, McMansion Hell, Joey, Catherine, Brandon, Hall, Vegreville Creek and Wetlands Fund, Kevin, Oliver, John, Johansson, Christina, Jared, Hannah, Katy Pye, Brandon, Gwen, Carly, Stephen, Botanical Tours, Moonwort Studios, Liba, Mohsin Kazmi Takes Pictures, doeg, Clifton, Stephanie, Benjamin, Eli, Rachael, Plant By Design, Philip, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Mark, Rens, Bendix, Irene, Holly, Caitlin, Manuel, Jennifer, Sara, and Margie.
