In Defense of Plants Podcast

It is hard to wrap your head around the floristic diversity of places like Southeast Asia. Indeed, it is one of the most biodiverse regions of the world. The challenges and excitement of cataloguing the myriad plant species that call this region home are what drive Kew's Head of Identification and Naming and Senior Research Leader (Asia) Dr. Tim Utteridge. His love for finding and describing plant...

It may be hard to believe but Antarctica has a green past. Throughout its history, our southern polar continent has been the home to a variety of now-extinct biomes and my guest today is responsible for uncovering the oldest of these remains. Dr. Erik Gulbranson is part paleoecologist and part paleoclimatologist and what he and his collaborators are learning from these fossilized ecosystems not on...

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 the California Academy of Sciences who have devoted their life to understanding and protecting these so-called living fossils. This episode was produced in part by Rens, Bendix, Irene, Holly, Clifton, Shane, Caitil...

Join me and my guest Robbie Blackhall-Miles as we discuss his love and passion for growing the remains of a flora whose lineage arose many millions of years ago.

Today we are joined by John Magee, landscape designer and co-host of The Native Plant Podcast. John has always been a fan of gardening with natives and has some wonderful insights about the culture of landscaping. Join us for a fun discussion centered around celebrating native flora. This episode was produced in part by Allan, Clifton, Sebastian, Holly, Katherina, Shane, Amy, Caitlin, Rosanna, Mar...

The title says it all. My guest today is Amy Hruska, a PhD student at the University of Hawai'i. Her research bridges the gaps between invasive species, extinction, and seed dispersal in Hawaiian forests. Join us for an enlightening discussion about where a botanist fits in to this system. This episode was produced in part by Allan, Clifton, Holly, Katherina, Shane, Amy, Caitlin, Rosanna, Mary Jan...

I think growing plants is one of the most important skills humanity has ever stumbled across. People like Dr. Chad Husby are a wonderful example of just how important it is. Whether its teaching the public, saving a species, or learning how to grow plants in space, botanical horticulture is vital. Join us for a fun discussion about what its like to be a professional plant grower at Fairchild Botan...

Carlos Magdalena has been called "The Plant Messiah" for good reason. His propagation work at the Royal Botanical Gardens at Kew has seen species like Nymphaea thermarum (the world's smallest water lily) and the Café Marron (Ramosmania rodriguesii) back from the brink of extinction. Join me for a discussion with this plant whisperer. This episode was produced in part by Allan, Clifton, Holly, Kath...

Few may realize just how important plants were to the great Charles Darwin. Luckily, Dr. James Costa is bringing Darwin's botanical interests to the forefront with his latest book, "Darwin's Backyard: How Small Experiments Led to a Big Theory." As if this book wasn't exciting enough, each chapter concludes with DIY instructions on how you and your friends and family can replicate some of Darwin's...

Many of us are aware that planting legumes helps enrich soils but how do they do this? By partnering with bacteria, of course! My guest today studies how this mutualistic relationship evolved and how it is maintained throughout various lineages. Dr. Katy Heath is a plant person at heart and she brings that passion with her to her lab as she tries to understand these evolutionary processes. Join us...

Ferns and lycophytes have been around for a long time. Still, they often get overshadowed by angiosperms but not in the Sessa lab! Our guest today is Dr. Emily Sessa, an assistant professor at the University of Florida. Her lab focuses on the interrelationships of these two great lineages and even offers the listener a unique opportunity to collaborate. This episode was produced in part by Allan,...

Mosquitoes are maligned the world over and often for very good reason. However, there are a plethora of different species of mosquito on this planet and many of them do not bite humans or spread disease. In fact, some of them are important pollinators. In this episode we take a closer look at an orchid that relies on mosquitoes for pollination. The one leaved rein orchid (Platanthera obtusata) gro...

The 'Ohi'a (Metrosideros polymorpha) is the dominant tree on the Hawai'ian Archipelago and it is under attack by two different species of invasive fungi. Trying to understand and combat the spread of these pathogens is one of the main focuses of our guest, Dr. James B. Friday. Together with multiple different stakeholders, they are trying to understand how these fungi got to the island and what ca...

Our guest today is Dr. Karl Niklas. His work utilizes mathematics to explain plant growth and form in relation to four basic physical constraints: 1) Plants have to capture sunlight and avoid shading their own leaves, 2) Plants have to support themselves structurally, 3) Plants have to conduct water to their various tissues, and 4) Plants must be able to reproduce effectively. Using these basic co...

I am back in Illinois and I met up with my good friend Steve (co-host of The Field Guides Podcast) to wax poetic about summer botanizing. Steve has spent most of his summer exploring Illinois while I have been busying myself in the southern Appalachian Mountains. We bring a lot of interesting species to the table in this episode, each with its own memorable experience. This episode was produced in...

Today we are continuing our conversation with Dr. James Costa. This week, we take a deeper look at the life of Alfred Russel Wallace, a man who independently began developing a theory of evolution. You will find out why we hardly remember Wallace for his contributions to this fascinating world of science and inquiry. This is a different kind of discussion than we normally have here at In Defense o...

For Dr. James Costa, a love of biology started early. It eventually evolved into a career studying social insects and their interactions with plants. It also evolved into a passion for the history of science, specifically that of evolutionary theory. Dr. Costa wears many hats and you will hear about some of them in part one of this two part episode! This episode was produced in part by Allan, Amy,...

Today we are talking about one of my favorite subjects - old growth forests. Joining us is Dr. Beverly Collins, an associate professor at Western Carolina University. Her work looks at the dynamics of old growth forests, especially as it relates to disturbances. She is especially curious about the role disturbance plays in the survival of understory herbs. This episode was produced in part by Mark...

In this episode, In Defense of Plants is going back in time a bit to my visit to San Francisco. What you are about to hear is a tour of Tilden Park's wonderful botanical garden whose purpose is the collection, growth, display, and preservation of the native plants of California. This was easily one of the most impressive living collections I have ever seen. The tour was led by none other than Bart...
