Ep. 247 - The Stories That Tree Rings Can Tell

January 12, 2020

Counting the rings of a tree can be so much fun. In the temperate zone, each ring marks a year in that tree's life. However, if you know what to look for, tree rings can tell you so much more. Dr. Valerie Trouet has made a career out of counting and measuring tree rings. Tree rings offer a surprisingly detailed window back in time and allows scientists like Dr. Trouet to understand everything from fire regimes to climate conditions. Even beyond that, tree rings can provide valuable insights into human history. Insights like this are the subject of Dr. Trouet's incredible book "Tree Story: The History of the World Written in Rings." Join us for an in depth look at the fascinating world of dendrochronology.

Ep. 207 - Into the Rooting Zone: Why Soil Carbon Matters

April 7, 2019

Grab your shovels because today we are heading underground to talk about soils. Joining us on this adventure is my friend and labmate Ron Salemme. Ron studies soil carbon cycling in the context of invasive plants and prescribed fire. In doing so, he works at the interface between plants and the soil environment where we are only just beginning to understand some of the most important processes on our planet. From dying microbes to plant exudates, Ron's work is helping us form a more complete picture of the role soil plays in storing carbon. This episode was produced in part by Brandon, Hall, Vegreville Creek and Wetlands Fund, Kevin, Oliver, John, Johansson, Christina, Jared, Hannah, Katy Pye, Brandon, Gwen, Carly, Stephen, Botanical Tours, Moonwort Studios, Lisa, Liba, Lucas, Mohsin Kazmi Takes Pictures, doeg, Clifton, Stephanie, Rachelle, Benjamin, Eli, Rachael, Anthony, Plant By Design, Philip, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Brian, Mark, Rens, Bendix, Irene, Holly, Caitlin, Manuel, Jennifer, Sara, and Margie.

Ep. 191 - The Changing Forests of the Andes

December 16, 2018

When it comes to our understanding of plants and climate change, the tropics are still a great unknown. However, the data we do have is telling us that our actions are already changing forests. Today we are joined by Dr. Ken Feeley to talk about some of his work looking at the forests of the Andes Mountains. You will soon learn just how difficult it can be to study such a biodiverse region. Nonetheless, Dr. Feeley and his colleagues are putting in great efforts to collect vital data on these species to help us better understand and act on conservation efforts. This episode was produced in part by Hannah, Katy Pye, Brandon, Gwen, Carly, Stephen, Botanical Tours, Moonwort Studios, Lisa, Liba, Lucas, Mohsin Kazmi Takes Pictures, doeg, Daniel, Clifton, Stephanie, Rachelle, Benjamin, Eli, Rachael, Anthony, Plant By Design, Philip, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Brian, Mark, Rens, Bendix, Irene, Holly, Mountain Misery Farms, Caitlin, Manuel, Jennifer, Sara, and Margie.

Ep. 189 - When Palms Grew in Wyoming

December 2, 2018

Join Dr. Sarah Allen and me as we journey back in time to the Eocene. Earth was a very different planet some 49 million years ago. Though we may recognize some Eocene flora, the combination of various plant lineages would be enough to make your head spin. Earth was experiencing a warming period and the plants had responded accordingly. Tropical species like palms were thriving in places like Wyoming and giant relatives of the redwoods covered much of North America and Asia. What Dr. Allen and her colleagues are learning about Eocene plant communities is not only interesting in its own right, it is helping scientists understand how ecosystems may respond to climate change into the future. This episode was produced in part by Brandon, Gwen, Carly, Stephen, Botanical Tours, Moonwort Studios, Lisa, Liba, Lucas, Mohsin Kazmi Takes Pictures, doeg, Daniel, Clifton, Stephanie, Rachelle, Benjamin, Eli, Rachael, Anthony, Plant By Design, Philip, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Brian, Mark, Rens, Bendix, Irene, Holly, Mountain Misery Farms, Caitlin, Manuel, Jennifer, Sara, and Margie.

Ep. 139 - Tropical Dry Forests

December 17, 2017

Despite representing nearly half of the tropical forests around the globe, tropical dry forest ecosystems have largely been overshadowed by rainforests. Sadly, most attention that has been paid to these diverse ecosystems has come in the form of agriculture. As such, the world has lost much of its old growth tropical dry forests. How these forests recover from such disturbance and how they are going to persist in the face of climate change are just some of the questions Dr. Jennifer Powers is trying to answer. Join us for a wonderful conversation about some of the most poorly understood ecosystems on our planet. This episode was produced in part by Daniella, Brodie, Kevin, Katherina, Sami & Sven, Sophia, Plants by Design, Mark, Rens, Bendix, Irene, Holly, Clifton, Shane, Caitlin, Rosanna, Mary Jane, Manuel, Jennifer, Sara, Sienna & Garth, Troy, Margie, and Laura.
