Microbes are everywhere, even in seeds! Indeed, seeds from various plants can host a community of different microbes. Despite how cool this sounds, we still have a lot to learn about seed microbiomes. Join me and Dr. Gilliam Burgmann as we explore questions like what kinds of microbes are present in seeds? How do these communities differ? Are microbes good, bad, or indifferent to the seeds that ho...

Coastal wetlands are among the most productive ecosystems on our planet. They are a boon for plants, animals, and people alike. However, sea level rise is changing these ecosystems and the communities that rely on them. Join me and Dr. Keryn Gedan as we explore the links between sea level rise, wetland migration, and ghost forests and learn how communities are bracing themselves for adapting to th...

Large seed dispersers are disproportionately affected by human disturbances like habitat loss and poaching. At the same time, a disproportionate number of tropical tree species rely on animals for seed dispersal. What happens when these animals disappear from an area? Do forests suffer and how might this impact things like carbon cycling and climate? Join me and Dr. Evan Fricke as we explore these...

Seed dispersal is a vital ecological process no matter what scale you look at. From the genetic diversity of plant populations to the impact of forests on climate, how plants move around the landscape and regenerate is one of the most important processes on Earth. So, what happens when plants lose seed their seed dispersers? How do things like poaching and habitat loss affect these ecological rela...

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...
