In Defense of Plants Podcast

Their ancestors once dominated the coal swamps of the Carboniferous Period, growing into massive trees that could reach upwards of 160 feet (50 m) into the canopy. Today, the quillworts (Isoetes spp.) are all that remains of this lineage. Though cosmopolitan in their distribution, quillworts can be hard to find unless you know where to look. Luckily, there are people like Dr. David Wickell who hav...

Self-Incompatibility is a means by which some plants prevent self-fertilization and promotes outcrossing. It has evolved independently in many different groups and plays a very important role in the ecology, evolution, and conservation of different species. In this episode, I sit down with Dr. Grace Burgin to explore the multitude of ways she is trying to understand self-incompatibility in the gen...

The Joshua tree (Yucca brevifolia) has attained celebrity status in recent times, but that hasn't always been the case. For over a century, the Joshua tree was viewed as a useless and repulsive plant that bucked all attempts to tame it. How our relationship with Yucca brevifolia went from hatred to worship is the topic of "Yuck", in which author Barret Baumgart dives into the history of this speci...

Whether you realize it or not, our lives depend on the native plant communities that comprise and support regional biodiversity. As we lose habitat, we lose species, and we lose the checks and balances that keep the living world functional. Scientists are increasingly uncovering the links between human health issues like infectious diseases and biodiversity loss and that is exactly what Dr. James...

On face value, flower colors would seem to have everything to do with pollination, but it is far more complex than that. The pigments that give flowers the colors we can see can have many different functions and how they evolve is a fascinating realm of research. Join me and Dr. Andrea Berardi as we explore floral coloration in two genera - Silene and Petunia. This episode was produced in part by...

Understanding the relationships among plants can reveal so much about the history of our planet and the mechanisms of evolution. This is why Dr. Peter Quakenbush has spent so much time trying to understand the genus Medinilla. You might be most familiar with Medinilla magnifica as a popular houseplant, this it is only the tip of the iceberg when it comes to the diversity of this genus. Join us for...

Changes in biodiversity are happening all over the globe. From losses to homogenization, understanding the affects of biodiversity change are paramount to understanding how ecosystems function. Nowhere is this more apparent than with plants. Join me and ecologist Dr. Jake Grossman as we explore the links between tree diversity and ecosystem functioning. This episode was produced in part by Austin,...

Say "old growth" and we all too often picture ancient forests with large, gnarly trees. However, forests aren't the only habitat types that can reach old growth status. Prairies, savannas, and woodlands can be old growth too and it is vital that we both protect and learn from them as they are one of the rarest habitat types on Earth. Join me and ecologist Dan Carter from The Prairie Enthusiasts as...

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.
