In Defense of Plants Podcast

Cities are usually designed with only humans in mind, but that doesn't mean myriad other forms of life aren't adapting to live in these human-dominated landscapes as well. My guest today is Jasmin Green, a PhD candidate at UC Davis who is very curious about the ecological dynamics of plant communities in urban environments. From why some plants can establish in cities while others cannot to how di...

Pollination is arguably among the most important ecological processes on our planet. Entire careers have been devoted to trying to understand the countless nuances to plant pollination and yet we have only uncovered the tip of the iceberg. In this episode, we are joined by pollination ecologist, Dr. Jeff Ollerton to talk about his new book "Pollinators & Pollination: Nature & Society," whi...

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 quest...

A lot of detective work goes into saving plants from extinction and that is what we are discussing in this episode. Dr. Anne Frances joins us to talk about all of the plant sleuthing she does as NatureServe's lead botanist. Her work has her investigating the status of everything from single sight endemics to crop wild relatives. This episode is proof that we have what it takes to save plants from...

Rock gardening is so much more than gardening with rocks. No one knows this better than Panayoti Kelaidis. A self-proclaimed acolyte in the cathedral of chlorophyll, Panayoti has spent a lifetime steeped in plants and gardening. As you will learn, rock gardening is truly a magnificent blend of science and art that celebrates plants as organisms and brings people together from all across the world....

In Defense of Plants is now a book! Hitting shelves on February 23rd, "In Defense of Plants: An Exploration into the Wonder of Plants" explores my introduction to the world of botany and the amazing ways plants make a living. Instead of me just talking at you for an hour, I figured I should let someone else take the wheel for a bit so I invited my buddy Bill Michalek from The Field Guides Podcast...

For those with even passing familiarity, the proteas represent something akin to botanical royalty. This family of plants exhibits a bewildering array of forms, lifestyles, and habitat preferences, which is why they were named in honor of the shape-shifting Greek god Proteus. Whereas Proteus was confined to the water, the proteas can be found growing terrestrially throughout the Southern Hemispher...

This episode occurs at the intersection of botany and geology, two inseparable components of the natural world. For Dr. David Charlet, what started with curiosity about a seemingly out of place population of conifers has developed into a life-long obsession with species distributions and deep time. Dr. Charlet specializes in the biogeographic history of the Great Basin and Mojave Desert with a spe...

We expand further on the topic of oak conservation in this episode by looking at two examples of in situ oak conservation projects. Joining us from the Morton Arboretum is Tree Conservation Ecologist, Dr. Silvia Alvarez-Clare to discuss her amazing community-based projects aimed at saving Quercus brandegeei and Quercus insignis. These efforts are all based on conserving these species where they gr...

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...

Imagine being able to travel back 120 million years to the Early Cretaceous and scoop up handfuls of the forest floor. The amount you would discover in that material would be mind blowing and, amazingly, this is essentially what my guest gets to do. Dr. Fabiany Herrera is a paleobotanist based at the Chicago Botanic Garden who is currently helping reconstruct the flora of an ancient Mongolian swam...

Grab your snorkel and goggles because this episode takes us underwater. I sit down for a conversation with Assistant Professor Dr. La Toya Kissoon-Charles about the ways in which aquatic plants both impact and are impacted by their watery environment. From insights into water chemistry and the impacts of land-use change to the potential to clean up polluted waters, Dr. Kissoon-Charles unveils an e...

You may have heard of the mineral gypsum through its use in making plasters, chalks, and drywall, but are you aware of its influence on plant speciation? Indeed, soils heavy in gypsum present unique challenges to plant growth but that doesn't mean plants haven't been able to conquer such substrates. In this episode, I sit down to talk with Dr. Mike Moore about his research on how gypsum-based soil...

What do cashews (Anacardium spp.), mangoes (Mangifera spp.), pistachios (Pistacia spp.), and poison ivy (Toxicodendron spp.) have in common? They are all members of the family Anacardiaceae! In this episode, I sit down with Deputy Executive Director at the United States Botanic Garden, Dr. Susan Pell, who has devoted her career to understanding this incredible and surprisingly diverse family. Join...

In this episode, we do a deep dive into the barberry family, Berberidaceae, with environmentalist, author, and garden designer Lyndon Penner. Many of us will be familiar with the Mahonias or the prickly barberry shrubs, but they overshadow some of the more interesting members of this clade. Join us as we talk about the wonderful diversity of woodland herbs and wax poetic about all the inspiration...

Dogs are among our oldest companions. Our propensity for cohabitation and collaboration leads to unique bonds that are rare in the animal kingdom. In this episode we sit down with members of Rogue Detection Teams to talk about how some dogs are even helping save plants. From finding invasive species to sniffing out plant diseases, dogs are proving to be excellent conservation assistants. Moreover,...

This episode takes a deep dive into the past, present, and future of herbaria. I sit down with Director of the William and Lynda Steere Herbarium, Dr. Barbara M. Thiers about her new book "Herbarium: The Quest to Preserve and Classify the World's Plants." Dr. Thiers has spent a lifetime thinking about and working in herbaria and she recognized the importance of telling their stories. Listen in as...

From plant conservation to food security, we desperately need to understand how plants fight disease. As you can probably imagine, the world of plant-microbe interactions is vast and complicated but that's where people like Dr. Kevin Cox Jr come in. Currently a post-doc at the Danforth Plant Science Center, his work has him looking at disease-causing fungi at high resolutions. By understanding the...

Plant poaching is abhorrent and we can’t work towards a solution without a proper understanding of the motivations behind it. That's where people like Dr. Jared Margulies come in. In this episode we sit down to talk about what he learned through investigating the illicit trade is one of North Americas most stunning succulents, Dudleya farinosa. What Dr. Margulies uncovered was a complex economy dr...

From feral goats, pigs, and deer, to the extinction of it's suspected pollinator, the ʻŌlulu (Brighamia insignis) has a lot stacked against it. Yet, despite being extinct in the wild, the ʻŌlulu is surprisingly common in cultivation all thanks for a handful of seed collections made a few decades ago. Today we are joined by Conservation Biologist for the National Tropical Botanical Garden, Seana Wa...

Plant perception: few topics are the subject of more pseudoscience and misinformation than this one. Luckily there are people like Dr. Lauren Erland who exist to shine a scientific light on the topic. Dr. Erland studies, among other things, the role of plant growth regulators in plant perception and response to changes in their environment, specifically serotonin and melatonin. Join us as we take...

Writer, naturalist, and gardener Dan Hinkley returns to the podcast to talk about his new book "Windcliff: A Story of People, Plants, and Gardens," which is a touchingly honest tale of his own journey in creating his own personal garden. Dan is unique in blending his own naturalist-brand of plant appreciation with sentiments of horticulture and design. Throughout we learn about just how personal a...

Whether we realize it or not, this planet and all life on it are influenced by grasses. Among the most important are grasses belonging to the tribe Andropogoneae. Members of this group include crops such as corn, sugarcane, and sorghum, as well as ecologically important species like big bluestem. Despite their importance, we know surprisingly little about these plants, especially as it related to...

Invasive species are second only to habitat destruction in causing loss of biodiversity on this planet. Moving one species to a habitat where it didn't evolve or even giving native species a new advantage can cause ripples that spread throughout the entire ecosystem. Returning to the podcast to talk about these issues is plant pathologist, Dr. Kristin Wickert. Join us and learn about the myriad wa...

This episode is all about one of the most difficult topics in natural history - extinction. Plants set the foundation for nearly all life on Earth and yet they receive a mere fraction of the attention and effort needed to conserve them. Recent estimates indicate that 40% of the world's plant species are threatened with extinction and that is a scary statistic. One of the biggest hurdles in the fig...
