In Defense of Plants Podcast

Phenology is defined as "the study of cyclic and seasonal natural phenomena, especially in relation to climate and plant and animal life." Far from being a fun topic to investigate, plant phenology is a very important component of how ecosystems operate. The timing of important events like bud break and reproduction can have massive implications on everything from insect population dynamics to rep...

Butterflies and plants are inextricably linked. It stands to reason then that if you want healthy butterfly populations, you first need plant diversity on the landscape. Join me and Dr. Katy Prudic as we explore her research into how we can better manage the human environment, especially in suburban and urban areas, to be good habitat for butterflies. Learn how citizen science opportunities are he...

Do you want to bring native plants into your life in ways that will inspire others? Do you want to turn whatever space you have into habitat that fosters biodiversity? Diving into the world of ecological landscaping may seem daunting at first, but books like "Prairie Up" helps turn the learning curve in an exciting on-ramp. Join me and author Benjamin Vogt as we dive into the inspiration and philo...

Orchid bees are not your average pollinators. Hailing from tropical regions of the Americas, these little gems have complex relationships with a variety of plants focussed on perfume production. Join Dr. Santiago Ramírez and me as we dive into the wildly fragrant world of orchid bee ecology and learn how their quest for scents has shaped myriad tropical plant lineages. This episode was produced in...

What does it take to reconstruct a plant that went extinct hundreds of millions of years ago? How do you find the right context to place it in when so much has changed? These are just some of the questions we explore in this episode. Dr. Jeff Benca returns to the podcast to talk to us about how he approaches paleobotanical reconstruction both as a scientist and an artist. This episode was produced...

The earliest days of land plant evolution have long thought to have occurred in a hot house environment fueled by high CO2 levels. However, recent investigations suggest this may not have been the case and that small plants, not forests, had a massive role to play. Join me and Dr. Tais W Dahl as we travel back over 400 million years to the Devonian Period and discuss how small relatives of lycopod...

Vanilla scent and flavoring is loved the world over, but what is the story behind vanillin, the compound responsible for producing these properties? Many theories as to its ecological function have been put forward over the last century and finally we can put the debate to rest. My guest today is Dr. Adam Karremans who teamed up with a handful of biologists to observe and experiment with Vanilla f...

The odds of any living material becoming fossilized are extremely rare, especially if that living thing is a moss, liverwort, or hornwort. It does happen, however, and my guest today is dedicating his career to studying and understanding what bryophyte fossils can tell us. We revisit a conversation with Alex Bippus, who at the time was a PhD student at Oregon State, to learn about his fascinating...

Have you ever wondered about the impact of outdoor recreation on plant communities? Trinie Chisholm certainly has. Together with her colleagues, Trinie sought to investigate how offroad vehicle and other type of trails are impacting plants in Canada's Castle Provincial Park. Her work is a great example of how multiple stakeholders can come together to collaborate on more sustainable outdoor recrea...

Many bats need forests and, as it turns out, those forests need bats. We are well aware that the majority of North America's bats eat insects, but what is the impact of their insectivorous diet on forest health? Join me and Dr. Lizz Beilke as we uncover the answers to this question and more. This episode was produced in part by Randi, Caelan, Tom, Don, Susan, Corbin, Keena, Robin, Peter, Whitney,...

We take plant roots for granted, but there was a time in Earth's history when roots had yet to evolve. As you are going to hear from Professor of Earth Sciences, Dr. Gabe Filippelli, when roots did evolve, they may have set in motion a mass extinction of oceanic proportions. Learn what he and his colleagues have discovered and what it can teach us about Earth's biosphere moving forward. This episo...

This episode is dedicated to the memory of world-renowned cycad expert Dr. Nathalie Nagalingum who sadly passed away. I first spoke with Dr. Nagalingum back in 2017 where she opened my eyes to the plight of cycads. Did you know that cycads are the most endangered group of organisms on the planet? We are officially facing a cycad crisis but luckily there are people like Dr. Nathalie Nagalingum from...

Tall trees are true marvels of nature in and of themselves, but the habitats they create can take our fascination and appreciation to whole new levels. Dr. Steve Sillett has spent his career climbing giant trees and uncovering remarkable insights into their ecologies. Join us for a celebration of tall trees and learn how we can better manage the forests they comprise. This episode was produced in...

The hawthorns (Crataegus spp.) are in intriguing group of small trees. They are members of a genus that has sparked plenty of controversy and debate among taxonomists for decades and it doesn't appear to be slowing down any time soon. Regardless of the confusion they cause, there is no denying that hawthorns are as beautiful as they are ecologically important. Join me and botanist Ron Lance as we...

For seagrasses, living life underwater comes with a lot of unique challenges, not the least of which is pollination. This is especially true when you consider the fact that their flowers are both ephemeral and borne submerged. Figuring out the means by which seagrasses reproduce is important to their conversation and restoration, but was largely unknown until about a decade ago. Join me and Dr. Vi...

I am a big fan of the "grow it to know it" philosophy. Growing plants provides so many important insights into the botanical world. However, for so many of us, figuring out where to start can be daunting. Botany, after all, is a massive subject. That is where books like "A Gardener's Guide to Botany" factor in. Dr. Scott Zona returns to the podcast to talk about his new book and why melding botany...

Insect herbivory is a major driver of ecosystem processes across ecosystems, but how has it changed through time? Wouldn't it be amazing to travel back through time to see how much plant-insect interactions have changed? Essentially, that is what Dr. Lauren Azevedo-Schmidt is able to do using both modern and fossilized leaves. Join us as we explore how much insect herbivory rates have changed thro...

What are the threats to all the trees in the U.S.? To answer this question, you first have to figure out how many species there are and comb through data gathered by hundreds of dedicated biologists, ecologists, and more. Join me and Dr. Murphy Westwood as we discuss the first comprehensive threat assessment for US trees that could not have been done without partners such as BGCI-US, NatureServe,...

Plant ecologist Sara Johnson and I look back at a recent botanical adventure in southern Australia with fondness.

Today we are focusing on a strange genus of plants in the family Euphorbiaceae. The Dalechampia can be found growing in tropical forests throughout much of the world. We revisit a 2018 discussion I had with Dr. Scott Armbruster, who has spent his entire academic career using Dalechampia as what he likes to call "a non-mode, model system" for studying the evolutionary ecology of pollinator syndrome...

The Wollemi pine is one of the world's rarest trees. These mysterious gymnosperms was unknown to science until 1994. Their discovery made headlines around the globe. My guest today, Dr. Heidi Zimmer, has the distinct honor of working with this wonderful species. Join us for a conversation all about Wollemia nobilis. This episode was produced in part by Caelan, Tom, Don, Susan, Corbin, Keena, Robin...

Grasslands are in desperate need of both protecting and restoring. These important and diverse ecosystems have long been viewed as less important than forests but that could not be farther from the truth. Join me and Dr. Katharine Suding as we look at the importance of old growth grasslands and what they can teach us about grassland restoration. This episode was produced in part by Caelan, Don, Su...

Plants help create soil just as much as they depend on it for their survival. Understanding how this affects the ecosystems that plants comprise can provide novel and important insights into ecosystem restoration and health. Soil geographer Dr. Jim Thompson joins us to discuss his recent work on red spruce (Picea rubens) soils and how it can be used to inform everything from red spruce restoration...

Ferns may have an ancient evolutionary history and enjoy something of a celebrity status among the botanically and non-botanically minded alike, but a fully sequenced fern genome has been hard to come by... until now. Join me and Dr. Blaine Marchant as we explore what it took to sequence the genome of the water fern (Ceratopteris richardii) and all of the amazing discoveries and questions they hav...

"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...
