In Defense of Plants Podcast

Sedges (genus Carex ) can be an intimidating group of plants to get your head wrapped around, but it doesn't have to be that way. One key element to understanding them is knowing what to look for, which is why I am so excited to talk about a new book/key to the oval sedges - “Carex of Illinois and Surrounding States”. Join me and authors Michael Murphy, Greg Spyreas, and Paul Marcum as we explore...

The odds of encountering a prickly pear cactus (Opuntia spp.) in your lifetime is high no matter where you live. That is how abundant, diverse, and charismatic these cacti truly are. For all of their intrigue, so much about these spiny succulents remains a mystery. Trying to understand their diversity is fraught with challenges, both physical and academic, but that hasn't dissuaded people like Dr....

Getting struck by lightning is always thought of as a bad thing, but what if it wasn't? Trees can't get up and escape when storms roll in and the chances of one getting struck by lightning increases as they grow taller. For at least one species of tropical tree, getting struck could actually be beneficial not only to individuals but also populations. Join me and Dr. Evan Gora as we look at the sho...

Go looking for information on rare plant population health and it can be surprisingly hard to come by. Plant monitoring, especially over the long term, is a challenge and data have not always kept up with the need. Dr. Michelle DePrenger-Levin and her colleagues at the Denver Botanic Gardens are doing their part to fix this and using some cool technology in the process. Join us as we discuss how d...

From why orchids need our help to cultivating in the lab and returning them to the wild, Saving Orchids is an inspirational read for anyone with even the slightest interest in nature and conservation. Join us for a peak at...

Visit the Sonoran Desert and you too will fall in love with its beauty and diversity. It is truly one of the most incredible places on earth. Dr. Ben Wilder agrees which is why he has dedicated his life to understanding the history of the Sonoran flora and using that knowledge to help ensure it has a future. Join us for a celebration of all things Sonoran Desert. This episode was produced in part...

What does it mean to be a successful plant? Reproduction? Population growth? What factors influence these important events and which contribute more to a population through time? The answers to these questions are very complex and climate change is only making things harder to understand. Dr. Amy Iler and her colleagues are not afraid to try and tackle such questions. Join us as we explore her res...

The woolly devil (Ovicula biradiata) is a fascinating and unique member of the daisy family (Asteraceae) that was only recently described to science. It was first found in Big Bend National Park in Texas and serves as an important reminder of not only the need for protecting wild places but also how little we still know about the natural world. Join me and Dr. Isaac Lichter Marck as we discuss wha...

Plants ARE habitat and that doesn't stop when they die. Countless species of microbes, fungi, arthropods, and more not only take up residence in dead plant material but also require it to complete their lifecycle. My guest today is Dr. Amy Zanne and she spends a lot of time thinking about the things that live in dead wood and their impacts on the world around us. As you will hear, these organisms...

The emergence of leaves, the blooming of flowers, the arrival of pollinators... these are all biological events that are closely tied to the changing seasons. The study of this linkage is called Phenology and my guest today wants to share her passion for this wonderful world of inquiry. Join me and Dr. Theresa Crimmins as we discuss the USA National Phenology Network and her new book "Phenology" t...

Parents and children don't always get along. Sometimes they can even be competitors. Conflicts often lead to interesting evolutionary adaptations and mosses are no stranger to this. Join me and Dr. Jessica Budke as we explore a familial tug of war going on all around us. This episode was produced in part by Rich, Shad, Maddie, Owen, Linda, Alana, Sigma, Max, Richard, Maia, Rens, David, Robert, Tho...

Spend any time in the southern Appalachian Mountains and you are bound to cross paths with Galax urceolata. This wonderful little evergreen herb seems to be at home in a variety of habitats from forest streams to granite outcrops and everywhere in between. It is also culturally significant and even suffers from poaching in some areas. Despite its place in Appalachian ecology and history, Galax hol...

Mangrove forests are dynamic places and so too are the people that study them. From carbon capture and peat formation, to restoration and hydrology, these coastal habitats offer curious minds plenty to ponder. Join me and Dr. Luke Lamb-Wotton as we explore the wonderfully complex world of these coastal ecosystems. This episode was produced in part by Rich, Shad, Maddie, Owen, Linda, Alana, Sigma,...

Paw paw (Asimina triloba) is a charismatic and special species. It is the most northerly growing member of a mostly tropical family. It also has considerable influence on its herbaceous neighbors. Join me and PhD student Anna Wassel as we explore the random world of pawpaw and understory herb community assembly. This episode was produced in part by Shad, Maddie, Owen, Linda, Alana, Sigma, Max, Ric...

Mosses, liverworts, and lichens live in a world of their own. Not unlike the trees they grow on, these tiny organisms must play out the dramas of obtaining the water, nutrients, and light they need to survive, they are just doing so on a much smaller scale. At the same time, they are supporting their own food webs that scale far bigger than their own lives. Join me and Dr. Greg McGee as we explore...

Invasive species reduce native biodiversity and hinder an ecosystem's ability to support life, including our own. Managing invasive species can be very challenging, but that doesn't intimidate people like Dr. Mike Schuster. Learn how he and his colleagues are using the ecological principal of biotic resistance to study how some native plants such as rye grasses (genus Elymus) can help control inva...

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! Revisit this conversation with 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 us as we...

January 2025 marks the 10 year anniversary (!!!) of the In Defense of Plants Podcast. To celebrate, I thought it would be fun to revisit the first episode of the podcast. Travel back a decade to a tiny, old Buffalo NY apartment where a young and naive Matt waxes poetic about his love for jewel orchids (Ludisia discolor) as a blizzard rages outside. This episode was produced in part by Linda, Alana...

The herbarium world is a fascinating one. These botanical repositories are goldmines of data and help us understand the present by looking at the past. But what kind of future questions can herbaria help solve? Experts say the opportunities are endless, but we will need new technologies to take full advantage. Join me and Curator and Director of the Herbarium at Missouri Botanical Garden, Dr. Jord...

Leave the leaves! It is a phrase you hear a lot these days, but why is it so important to keep leaves and other plant debris on your landscape? These are the questions that drive Dr. Max Ferlato. Leaf litter and other plant debris provides vitally important habitat for myriad organisms including species important for pollination and pest control. Moreover, a little bit of leaf litter can go a long...

What is a species? On the surface, this seems like an easy question to answer. Get a bunch of biologists in the room together and you will quickly see it can be a bit of a loaded question. Questions like this are what drive scientists like Dr. Robert Laport. By looking at genome duplication events in plants like creosote bush (Larrea tridentata), he and his lab are curious how vast differences in...

Bees run the gamut from generalists to specialists. Whereas the generalists visit a variety of plants for the resources they need, many specialists exist on a single species. Such is the case for at least 20 different bees living in Southwestern North America who specialize on the pollen of the creosote bush (Larrea tridentata). In geologic terms, creosote is a relative newcomer to the Southwest a...

Tubers, corms, taproots, bulbs... There are many different kinds of underground storage organs in the plant world. Moreover, they form from many different kinds of plant tissues. This begs the question, why are there so many variations on the theme of energy storage? Join me and Dr. Carrie Tribble as we explore phylogenetic and trait-based approaches to understanding the evolution and development...

Domestication is a spectrum, especially for botanical crops. Regardless of where a plant is on that spectrum, it nevertheless has a wild origin. Understanding those origins can not only help us understand the plants better, but also our history as a species as well as open the door to future possibilities. Sadly, many of the wild relatives of crops are both poorly understood and in desperate need...

It is hard to believe, but you are about to listen to the 500th episode of the In Defense of Plants Podcast. So much has happened over the nearly 10 years this podcast has been running, and none of it would be what it is today without YOU, the listener. So, in celebration of the big 5 0 0, the wonderful Sara Johnson turns the tables and sits down to ask Matt some questions about what it is like to...
