In Defense of Plants Podcast

Treacherous topography can often serve as a safeguard for rare plant populations. Being difficult or even impossible to reach can protect plants from the myriad pressures that threaten them. Imagine what we could find tucked away among cliffs and ledges where most animals cannot venture. My gust today has managed to find a novel way of surveying plant communities in such habitats. Joining us is GI...

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 peopl...

This episode is dedicated to the trade of a culinary ingredient that involves multiple orchid species. Salep is derived from the tubers of many terrestrial orchids and no one really understands how modern demand for this ingredient is affecting their populations in the wild. Joining us to talk about this are PhD candidate Martha Charitonidou and Dr. John Halley from the University of Ioannina in G...

When we think of biodiversity and evolution, the tropical regions of our planet are frequently touted as hotspots for speciation. Indeed, the tropics house more species than most other regions, however, that doesn't mean that temperate areas haven't contributed to the diversity of life on this planet. Recent work has revealed that one of the largest clades of flowering plants, the rosids, are evol...

There are many ways to make hiking one of the most sustainable and environmentally friendly activities on Earth, but building trails on rare and unique plant communities is not one of them. Sensitive plants and habitats can be destroyed in the blink of an eye by trampling, which is why any good trail system needs to put plant conservation at the forefront. This is exactly what we are talking about...

In this episode we are joined by Conservation Horticulturist Emma Neigel of the Atlanta Botanical Garden to talk about the intersection of horticulture and conservation. When it comes to plant conservation, it isn't enough to just study why plants are rare, we must also learn what they need to grow and thrive. Being able to grown and propagate rare plants offers many species the hope of a brighter...

There is a lot of information out there on which plants to choose for your garden. Often this information is geared towards a wide audience living in vastly different climate zones. As such, it can be extremely difficult to figure out what will work best for you. That is why I am excited to sit down for a conversation with Lauren Muller, the Conservation Outreach Coordinator for the State Botanica...

The Glossopteris flora is one of the most important links that we have to the Permian Era. These trees dominated the supercontinent of Gondwana from around 299 to 230 million years ago and their fossilized remains have dazzled the human mind for centuries. Despite their popularity, Glossopteris mysteries abound. That is where scientists like Aviwe Matiwane come in. Aviwe is utilizing skills she pi...

In this episode we look at what's going on inside the pitchers of carnivorous pitcher plants. Besides functioning as organs for prey capture and digestion, these highly modified leaves also serve as miniature ecological communities that have a lot to teach us about symbioses and evolution. Joining us to talk about this Dr. Kadeem Gilbert who has spent the last few years of his life studying pitche...

With insects on the decline around the globe, the need for native bee understanding and appreciation has never been more apparent. While some native bees are super charismatic and well known,many more are cryptic and poorly understood. That is where people like author and naturalist Heather Holm come in. Heather is devoted to doing everything she can to bring native bees into the spotlight. From p...

The human population of the Sonoran Desert is growing quickly, developing the surrounding landscape at an alarming pace. At the same time, botanists are racing to understand the fate of this so called "green deserts flora." In this episode we learn what it takes to properly assess a regions flora for extinction risk and how that information is being used across borders to protect the botanical div...

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 muc...

This episode we are joined by Colah B. Tawkin, host of the incredible Black in the Garden, a podcast that "resides at the intersection of Black Culture and horticulture." For Colah, gardening has been revolutionary in many ways. Join us as we sit down for an in depth conversation about her journey into gardening and podcasting and how that has revolutionized her connection to plants, to life, to t...

This episode is all about the work being done by The American Chestnut Foundation and their partners to save the American chestnut (Castanea dentata) from extinction. Ravaged by an invasive fungal pathogen, this tree went from a dominant species in our forest to a spattering of dwindling stump sprouts barely hanging on in the understories of eastern North American forests. Join me as I sit down wi...

This episode is all about celebrating native plants both in the wild and in the garden. We are joined by environmentalist, author, and garden designer Lyndon Penner to talk about his life-long obsession with Canada's amazing diversity of native plants. From the mountains to the prairies, Lyndon is a lover of all things botanical. He began growing plants at the tender age of 3 and designed his firs...

One cannot overstate the power of gardening to calm the mind, reinvigorate passion, and bring people together. Understanding and growing plants is one of life's greatest joys and that is exactly the sentiment our guest this week wants to share with the world. Joining us is Derek Haynes or as you may know him, The Crazy Botanist. Derek has been obsessed with plants and nature since he was a child a...

In this episode, we are joined by PhD student Melissa Díaz-Morales and director of the Lankester Botanical Gardens Dr. Adam Karremans to look at how flies have managed to influence the evolution of the largest subtribe of orchids in the world - the pleurothallids. This remarkable group of orchids is home to over 5,000 unique species and presents some of the most stunning and complex floral morphol...

Historically speaking, palm taxonomy has been a bit tricky. This is due in large part by the difficulty in collecting and preparing proper specimens. Thankfully, with the advent of affordable DNA technologies, botanists are gaining new insights into palm diversity that aren't possible based on morphology alone. My guest today is Dr. Andrew Henderson of the New York Botanical Garden who has dedicat...

In May of 1980, Mount St. Helens erupted, creating a path of destruction for hundreds of miles. No one thought life would return to that stretch of mountain for decades but they were wrong. In only a few short weeks, plants began sprouting and fungi started fruiting. The ecology of Mount St. Helens has been full of surprises ever since and that is exactly the topic of this episode. Joining us is a...

What does it take to live many hundreds or even thousands of years? For trees, it often means growing in places like cliffs where few other things can. My guest today has studied ancient cliff dwelling trees from all over the world and has uncovered some of the oldest living forests on our planet in the process. Joining us is Dr. Doug Larson whose work demonstrates that, far from excluding life, e...

Longleaf pines once covered 90 million acres of southeastern North America. Today, human development has seen that number reduced down to 3 million acres. The decline in this tree has come at great cost to the ecosystems it once comprised. From the longleaf pine itself to one of the most biodiverse understory plant communities on the continent, these habitats are vital to ecosystem health. Luckily...

This week we are joined by director of The University of Minnesota Center for Forest Ecology, Dr. Lee Frelich to discuss an invasive species problem that threatens plant diversity and ecosystem functioning wherever it occurs. Earthworms are very powerful ecosystem engineers. They alter the entire structure of the soil, affecting everything that grows there. Invasive worms are changing entire ecosy...
