Ep. 319 - Evolution of the Seed

In Defense of Plants Podcast ·

2021/05/30

Seeds are among the most important biological structures on this planet. Seeds have been instrumental in the diversification of plants, allowing them to spread into new habitats all over the globe. In fact, you and I would not be here if it were not for seeds. For these reasons and more, Dr. Cecilia Zumajo is fascinated by how seeds evolved. By looking at the genetic mechanisms that control seed development in various gymnosperms, Dr. Zumajo is opening new doors into our understanding of the

Ep. 318 - The Challenges of Protecting an Endemic Mint

In Defense of Plants Podcast ·

2021/05/23

More than half of the species on the Endangered Species List are plants and yet plants receive less than 5% of all conservation funding. If we care about slowing or reversing biodiversity loss, we need to start prioritizing plant conservation efforts. Joining us to talk about this is plant conservationist Sara Johnson. Sara's work focuses heavily on what it takes to protect rare plants like the Florida endemic mint, Macbridea alba. Join us for an in depth look at the work that goes in to protecting

2021/05/09

The asteroid that slammed into the Yucatan Peninsula some 66 million years ago marked the end of the Cretaceous and the reign of the dinosaurs. As famous as this extinction event is, we know considerably less about how such disturbances affected ecosystems like tropical rainforests. That is where people like Dr. Mónica Carvalho come in. Together with her colleagues, Dr. Carvalho is using vast amounts of fossil evidence from both before and after the asteroid impact to paint a picture of how the

2021/04/04

This episode is all about the fascinating world of oak seed dispersal. Many of us have undoubtedly enjoyed watching frenzied squirrels and jays hurriedly collecting and stashing acorns. But such observations are only the tip of the extremely complex iceberg of oak seed dispersal. Join ecologist Dr. Michael Steele and me as we discuss his new book "Oak Seed Dispersal: A Study in Plant-Animal Interactions," which brilliantly outlines decades of research on this topic.

Cities are usually designed with only humans in mind, but that doesn't mean myriad other forms of life aren't adapting to live in these human-dominated landscapes as well. My guest today is Jasmin Green, a PhD candidate at UC Davis who is very curious about the ecological dynamics of plant communities in urban environments. From why some plants can establish in cities while others cannot to how different microclimates and maintenance regimes structure plant communities in vacant lots, there are

For those with even passing familiarity, the proteas represent something akin to botanical royalty. This family of plants exhibits a bewildering array of forms, lifestyles, and habitat preferences, which is why they were named in honor of the shape-shifting Greek god Proteus. Whereas Proteus was confined to the water, the proteas can be found growing terrestrially throughout the Southern Hemisphere where they face myriad environmental threats. Indeed, the most recent IUCN Red List Assessment has
