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. 361 - In Praise of Ancient Trees

March 20, 2022

For trees, living for hundreds or even thousands of years is akin to winning the lottery. So many things can go wrong between germination and living long enough to be considered ancient. My guest today is Dr. Chuck Cannon of The Morton Arboretum and he wanted to know what those odds really looked like. Using forest modelling, he and his colleagues now have a better idea of just how special ancient trees truly are and why they are so important at all scales from individual to species to entire ecosystems. This episode was produced in part by Pamela, Peter, Andrea, Nathan, Karyn, Michelle, Jillian, Chellie, Linda, Laura, Miz Holly, Christie, Carlos, Paleo Fern, Levi, Sylvia, Lanny, Ben, Lily, Craig, Sarah, Lor, Monika, Brandon, Jeremy, Suzanne, Kristina, Christine, Silas, Michael, Aristia, Felicidad, Lauren, Danielle, Allie, Jeffrey, Amanda, Tommy, Marcel, C Leigh, Karma, Shelby, Christopher, Alvin, Arek, Chellie, Dani, Paul, Dani, Tara, Elly, Colleen, Natalie, Nathan, Ario, Laura, Cari, Margaret, Mary, Connor, Nathan, Jan, Jerome, Brian, Azomonas, Ellie, University Greens, Joseph, Melody, Patricia, Matthew, Garrett, John, Ashley, Cathrine, Melvin, OrangeJulian, Porter, Jules, Griff, Joan, Megan, Marabeth, Les, Ali, Southside Plants, Keiko, Robert, Bryce, Wilma, Amanda, Helen, Mikey, Michelle, German, Joerg, Cathy, Tate, Steve, Kae, Carole, Mr. Keith Santner, Lynn, Aaron, Sara, Kenned, Brett, Jocelyn, Ethan, Sheryl, Runaway Goldfish, Ryan, Chris, Alana, Rachel, Joanna, Lori, Paul, Griff, Matthew, Bobby, Vaibhav, Steven, Joseph, Brandon, Liam, Hall, Jared, Brandon, Christina, Carly, Kazys, Stephen, Katherine, Mohsin Kazmi Takes Pictures, Manny, doeg, Daniel, Tim, Philip, Tim, Lisa, Brodie, Bendix, Irene, holly, Sara, and Margie.

Ep. 332 - The Ecology of Douglas Fir

August 29, 2021

In this episode, we celebrate one of the most venerable conifers in North America - the Douglas-fir (Pseudotsuga menziesii). This wide ranging species can establish early after disturbance and live for centuries, bolstering the ecology of the forests it comprises. Joining us for this celebration is arborist Casey Clapp, co-host of the wonderful Completely Arbortrary Podcast. Listen in as we wax poetic about the amazing Douglas-fir! This episode was produced in part by Jeremy, Suzanne, Kristina, Christine, Silas, Michael, Aristia, Felicidad, Lauren, Danielle, Allie, Jeffrey, Amanda, Tommy, Marcel, C Leigh, Karma, Shelby, Christopher, Alvin, Arek, Chellie, Dani, Paul, Dani, Tara, Elly, Colleen, Natalie, Nathan, Ario, Laura, Cari, Margaret, Mary, Connor, Nathan, Jan, Jerome, Brian, Azomonas, Ellie, University Greens, Joseph, Melody, Patricia, Matthew, Garrett, John, Ashley, Cathrine, Melvin, OrangeJulian, Porter, Jules, Griff, Joan, Megan, Marabeth, Les, Ali, Southside Plants, Keiko, Robert, Bryce, Wilma, Amanda, Helen, Mikey, Michelle, German, Joerg, Cathy, Tate, Steve, Kae, Carole, Mr. Keith Santner, Lynn, Aaron, Sara, Kenned, Brett, Jocelyn, Ethan, Sheryl, Runaway Goldfish, Ryan, Chris, Alana, Rachel, Joanna, Lori, Paul, Griff, Matthew, Bobby, Vaibhav, Steven, Joseph, Brandon, Liam, Hall, Jared, Brandon, Christina, Carly, Kazys, Stephen, Katherine, Mohsin Kazmi Takes Pictures, Manny, doeg, Daniel, Tim, Philip, Tim, Lisa, Brodie, Bendix, Irene, holly, Sara, and Margie.

Ep. 308 - The Street Life of Trees

March 14, 2021

What do street trees and oceanic islands have in common? It turns out a lot, at least from an ecological perspective. I sit down with Dr. Robert Warren to explore questions like do street trees constitute a functioning forest or a beautiful garden? What role do humans play in the ecology of street trees? And, how do we do better for ecology in human-dominated areas? We also discuss how these questions and more have led to the creation of a wonderful "guide" to street trees called "The Street Life of Trees: An Urban Guide" which irreverently and surreptitiously introduces readers to complex ecological science from an artistic perspective. Join us for a fascinating discussion about the ecology of street trees. This podcast was produced in part by Cari, Laura, Kali, Margaret, Mary, Connor, Nathan, 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.

Ep. 274 - Hollow Trees = Habitat

July 19, 2020

Move over raccoons and squirrels, hollow trees have some additional residents to support. Joining us on this episode are Dr.'s Lary Reeves and Andrei Sourakov to talk to us about how hollow trees are proving to be great spots to find massive congregations of moths, mosquitoes, and many other arthropods. When you consider how many hollow trees are on the landscape, you begin to realize just how much habitat these trees can provide. This episode also stands as proof of the power of natural history observations. By taking the time to observe nature no matter where you are, amazing discoveries will be made!
