Besides pollination, what do flowers and bees have in common? Microbes, of course! From mutualists to pathogens and everything in between, Dr. Quinn McFrederick wants to know how plants, bees, and microbes interact. Join us for a deep dive into our growing understanding of these important relationships. This episode was produced in part by Heidi, K…

Succulent poaching is a global black market business. The demand for succulents of all kinds is putting undue pressure of myriad species, many of which are on the brink of extinction. Join me and Dr. Jared Margulies as we talk about his new book "The Cactus Hunters: Desire and Extinction in the Illicit Succulent Trade" and learn how he followed the…

Who hasn't marveled at the fossilized remains of a dinosaur? Though their lineage lives on today in the form of birds, historically, dinosaurs were once far more diverse. Needless to say, they shaped the world around them just as much as the world shaped them, and this certainly included interactions with plants. Plant eating dinosaurs were some of…

The shoal lily (Hymenocallis coronaria) is a truly special plant. It is found in only a few rivers throughout southeastern North America where it will only grow in rocky shoals. It makes its living by wedging its bulb and contractile roots into rock crevices where clean, swift moving water washes over submerged bedrock. Sadly, wanton destruction of…

Plants are habitat! This means that to restore ecosystems, we would be wise to start with plants. Such is the case for the spruce-fir forests of southern Appalachia, which are among the rarest habitat types on the continent. Join me and Kelly Holdbrooks of the Southern Highlands Reserve as we explore their collaborative efforts to get red spruce (P…

Chara represent the earliest stages of true plant evolution. They are also model organisms for a wide variety of research questions. Join me as we revisit an intriguing discussion with Dr. Mary Bisson from the University at Buffalo. This episode was produced in part by Sea, Shannon, Thomas, Will, Jamie, Waverly, Brent, Tanner, Rick, Kazys, Dorothy,…

This episode celebrates moths as pollinators. We ignore or even malign moths at our own peril. Dr. Stephen Robertson joins us to talk about how even crop pests can act as important pollinators. From their bewildering numbers to the ways they interact with daytime pollinators, Dr. Robertson will open your mind to the amazing and understudied world o…

What drives orchid evolution? Why are places like Colombia so rich in orchid diversity? What constitutes a species across different orchid genera? Questions like these are what drive Dr. Tatiana Arias' research. Join us as we explore how she is attempting to tackle said questions and more. This episode was produced in part by Sea, Shannon, Thomas, …

With approximately 60 species spread across four families, seagrasses are a wonderfully diverse group of marine aquatic plants. They are also extremely important both ecologically and economically. From supporting massive fisheries and reducing erosion to sequestering massive quantities of greenhouse gases, simply put, we can't overemphasize the im…

Lycopods and their relatives enjoy a nearly global distribution today, but extant diversity is still a mere shadow of what it once was. My guest today is Paleobotanist Meg Nibbelink and she is working to understand just how much this charismatic group of plants has changed over their long history on this planet. Join us for a fun and interesting co…

What affects mycorrhizal communities? How do these communities influence trees and their seedlings? Do the relationships differ between angiosperms and gymnosperms? Where do we draw the line between science and conjecture? These questions and more are what drive Dr. Justine Karst's research. Join us as we explore what we do and do not know about co…

Plants and arthropods have a long evolutionary history that involves plenty of interaction. If you know where to look, evidence of such history can be found in fossil plant remains. We revisit a discussion with Dr. Gussie Maccracken who discovered the oldest remains of one of the most common, yet poorly understood plant/animal mutualisms on our pla…

Alabama is known for things like football, but thanks to the efforts of people like Dr. Brian Keener, it is also coming to be known for its bewildering plant diversity. North America's glacial past coupled with Alabama's unique geology means a lot of plants call this region home and some of them are found nowhere else in the world. Join me and Dr. …

In this episode, we continue our journey in the world of mycorrhizal interactions with Dr. Jason Hoeksema. Join us as we investigate the ecological and evolutionary consequences of interactions between trees and mycorrhizal fungi and learn how complex and complicated these relationships truly are. This episode was produced in part by Jamie, Brent, …

How does habitat size affect plant populations? What happens to plants and insects when two smaller habitats are connected by a habitat corridor? These are the kinds of questions Dr. Julian Resasco likes to ask. Join us for a discussion about the dynamics of habitat fragmentation. This episode was produced in part by Jamie, Brent, Tanner, Rick, Kaz…

The concept of the wood wide web in which trees are connected with one another via underground fungal networks has captured imaginations around the globe. The idea that trees may be sharing resources and communicating in seemingly altruistic ways is enticing, but is it true? The data suggest that this is more journalistic fiction than fact. Joining…

Galls are perplexingly complex and, in many ways, mysterious structures. Galls are induced by another organism living within the tissues of the host plant. They can occur on a variety of plant organs and come in variety of shapes, sizes, and colors. Join and and Dr. Antoine Guiguet as we explore the wonderful world of galls and learn what his work …
