In Defense of Plants Podcast

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...

Aspen (Populus tremuloides) are synonymous with many habitats throughout North America. This tree is a species of superlatives, but its grandeur doesn't mean it is immune to threats. In fact, in many areas of its range, aspen is in decline. Join me and Dr. Connor Crouch as we explore what he and his colleagues are learning about aspen health and how that can be used to improve forest health into t...

Protecting and restoring biodiversity in a place as biodiverse as Ecuador is no small task. You have to work hard and collaborate and that is exactly what the folks at Jocotoco Conservation Foundation. From protecting land and engaging communities, to research and restoration, their multifaceted efforts stand as a glorious example that conservation success stories are possible. Join me and Conserv...

One cannot overemphasize the importance of plant/pollinator interactions. The world as we know it would not exist without these complex components of ecology. Getting good data, and more importantly, making those data useful is important in conserving and restoring plants and their pollinators. Join my and Dr. Chris Cosma of Conservation Biology Institute as we explore how he and his colleagues ar...

Counting the rings of a tree can be so much fun. In the temperate zone, each ring marks a year in that tree's life. However, if you know what to look for, tree rings can tell you so much more. Dr. Valerie Trouet has made a career out of counting and measuring tree rings. Tree rings offer a surprisingly detailed window back in time and allows scientists like Dr. Trouet to understand everything from...

Novel approaches are always fun. Nowhere is this more apparent than in today's podcast. We revisit a conversation with Dr. Camille Holmgren from SUNY Buffalo State about her research reconstructing ancient desert climates using pack rat middens. Join us for a fun and interesting discussion that will take you back thousands of years in the past. This episode was produced in part by Maia, Rens, Davi...

The Mazon Creek Fossil Formation is famous the world over for the exquisite preservation of soft tissues in animals. These rocks provide pristine snapshots of everything from extinct worms and jellyfish to sharks and even the mysterious Tully Monster. For all that these fossils have taught us about the animals of this long extinct ecosystem, we know far less about the plants that supported this di...

"Benefitting pollinators" is a phrase that gets used a lot, especially in gardening circles. While most of us will agree with the sentiment, what does it mean in practice? How does one "benefit" pollinators in their community? There are a lot of great ways to do this, especially when it comes to native plants, but finding good, digestible information can be overwhelming. Thankfully organizations l...

Restoring healthy wetlands isn't an easy task. Often times, altered hydrologic cycles means wetlands no long act like they once did. Nevertheless, the many ecological and cultural benefits of functioning wetlands means that wetland restoration is certainly worth the time, money, and effort. Join me and Dr. Gary Sullivan of The Wetlands Initiative as we look at how data, art, and will power combine...

Healthy wetlands are vital to maintaining biodiversity and a healthy way of life for us. Sadly, we haven't always treated wetlands like the essential habitats that they are. While protecting natural wetlands is a must, we also need to understand how to restore them and plants play a major role in such efforts. Join me and Katie Kucera of The Wetlands Initiative as we take a botanical look at what...

Pinesap ( Monotropa hypopitys ) produces no leaves nor any chlorophyl. It “eats” fungi and can be found growing in many areas around the globe. It flowers in spring, fall, and summer and noby really knows if it is a single species or many. Despite its uniqueness, relatively little scientific attention has been paid to this little parasitic plant. Join me and Bill Michalek of The Field Guides Podca...

The Adirondack Mountains are home to a remarkable diversity of plant species. Situated in northern New York, these mountains are harsh enough that they foster a thriving alpine community. Despite their ability to handle some of the worst weather conditions, alpine plants can be quite sensitive to human traffic. With more and more people flocking to these mountains every year, concern was growing t...

Variegation among leaves is a fascinating phenomenon. Though plant breeders have accentuated this trait in a variety of cultivated plants, variegation does occur naturally as well. Its function isn't well understood for most species either. Such is the case for two species of wild ginger in the genus Hexastylis. Join me and Dr. Cierra Sullivan as we explore variegation in Hexastylis heterophylla a...

Fossils offer some of the best evidence of how diverse various branches of the tree of life once were. They help us understand speciation and extinction as well as biogeography. Dr. Steve Manchester has spent much of his career using fossilized seeds to understand the ancient histories of flowering plants such as the walnut family (Juglandaceae). Join us as we explore the ins and outs of a career...

Sedges are a complex group of plants in the family Cyperaceae. Within this family lies the genus Carex, which boasts ~2000 species found in all kinds of habitats. From specialists to generalists, there seems to be no lifestyle the sedges have not experimented with. But how did all this sedge diversity come to be? That is the question Dr. Andrew Hipp and his colleagues are trying to answer. Join us...
