In this episode of “A Botanical Podcast!” host Shiran Ben Zeev and Dr. Jessica Savage have a wide-ranging conversation about how flowering plants respond to shifting seasonal changes in temperatures, especially when those changes are unpredictable—early warming periods (false springs), followed by light or hard freezes. What is the difference between plants that flower and those that wait? What is the impact of freezing on plants in flower? Jessica draws on research by her and people in her lab who are working to help us better understand the physiological basis of plant phenology and seasonality.

Jessica is a whole plant physiologist with expertise in vascular physiology, floral physiology, phenology, and physiological ecology in seasonally cold climates. She has a strong disposition toward research tied to the phloem (she must have a sweet tooth!). She is an Associate Professor at a primary undergraduate institution and has a passion for mentoring undergraduate and graduate students (especially master’s students). She developed and runs a community-engaged research program focused on tree phenology in coastal forests around Lake Superior and is the Chair of the Physiological and Ecophysiological Section of BSA. Before starting as a faculty member, she was a Putnam Research Fellow at the Arnold Arboretum and a postdoctoral fellow at Harvard University. She received her PhD from the University of Minnesota in Plant Biological Sciences. The research discussed in the podcast was funded by the National Science Foundation (IOS 1656318).

Is it better/more advantageous to be a juvenile or an adult? As with humans, in plants, "it’s complicated"! In this episode of “A Botanical Podcast!” host Shiran Ben Zeev and Erica Lawrence-Paul discuss vegetative phase change in plants, i.e., the transition between juvenile and adult phases of vegetative growth. This transition can be visually subtle and easy to overlook in many species; however, morphological and physiological differences between juvenile and adult phases can lead to meaningful differences in plant and tissue function.

Dr. Erica Lawrence-Paul is an NSF postdoctoral fellow in Dr. Jesse Lasky’s lab in the Department of Biology at the Pennsylvania State University. She earned her doctorate at the University of Pennsylvania, studying the ecophysiological significance of the plant developmental transition, vegetative phase change, with a particular focus on photosynthetic and leaf carbon economic traits. Her current work focuses on understanding how natural variation in the timing of vegetative phase change and phase-specific differences in stress tolerance contribute to plant abiotic stress response and local adaptation.

In this episode, the host Shiran Ben Zeev and guest Jordan Dowell nerd out on a discussion of how plants choose to defend themselves against predators and/or manipulate other organisms to help them live their best lives, and how plants use chemistry to communicate---and what we can learn from that. They talk about the special challenges of surviving and thriving in harsh environments and touch on the evolution of chemical diversity and the effects of chemical diversity on organismal interactions across spatial and temporal scales.

Dr. Jordan Dowell is an assistant professor at Louisiana State University and an Associate Editor of the BSA's Applications in Plant Sciences. He studies the evolutionary ecology of plant-plant chemical communication and the impacts of multifunctional traits on biotic interactions from single-cells to landscapes using various techniques, from metabolomic and genomic approaches to remote sensing and field-based studies.
