Ep. 503 - Pollen Specialization

Bees run the gamut from generalists to specialists. Whereas the generalists visit a variety of plants for the resources they need, many specialists exist on a single species. Such is the case for at least 20 different bees living in Southwestern North America who specialize on the pollen of the creosote bush (Larrea tridentata). In geologic terms, creosote is a relative newcomer to the Southwest and trying to understand how so many bee species have come to specialize on its pollen and how differences in flowering phenology across its range affect their lifecycle has been a mainstay of Dr. Bob Minckley's career. Join us as we take a dive into the mysterious world of pollen specialization.

Ep. 356 - Pollen & Plant Stress

Pollen, stress, ecosystem health... These three things are more connected than you may think. Join me and my guest Dr. Jeff Benca as we dive into research that is uncovering a whole new way to gauge how plants and the ecosystems they comprise react to everything from odd warming patterns to global catastrophe.

Ep. 316 - How an Asteroid Changed Neotropical Rainforests

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 tropical rainforests of what is now Colombia were affected by this global catastrophe. From the rise of angiosperms to a complete overhaul of insect/plant interactions, you will be amazed at what these fossils can tell us.

Ep 309 - Plants, Pollinators, Nature, and Society

Pollination is arguably among the most important ecological processes on our planet. Entire careers have been devoted to trying to understand the countless nuances to plant pollination and yet we have only uncovered the tip of the iceberg. In this episode, we are joined by pollination ecologist, Dr. Jeff Ollerton to talk about his new book "Pollinators & Pollination: Nature & Society," which takes a deep dive into what we currently know about pollination, why it is important for both nature and society, and what we can do to protect these invaluable ecological interactions. If you care at all about the natural world, this is one episode you don't want to miss. This podcast was produced in part by Laura, Cari, Laura, Kali, Margaret, Mary, Connor, Nathan, Jan, Jerome, Brian, Melody, Azomonas, Ellie, University Greens, Cynthia, John, Ashley, Peter, Cathrine, Melvin, OrangeJulian, Porter, Grif, Jules, Joan, Les, Marabeth, Ali, Margaret, Southside Plants, Robert, Keiko, Bryce, Brittany, Helen, Amanda, Mikey, Rhiannon, Michelle, Kate, German, Joerg, Alejandra, Cathy, Jordan, Judy, Steve, Kae, Carole, Mr. Keith Santner, Dana, Chloe, Aaron, Sara, Kenned, Vaibhav, Kendall, Christina, Brett, Jocelyn, Kathleen, Ethan, Kaylee, Runaway Goldfish, Ryan, Donica, Chris, Shamora, Alana, Laura, Alice, Sarah, Rachel, Joanna, Griff, Philip, Paul, Matthew, Clark, Bobby, Kate, Steven, Brittney, McMansion Hell, Joey, Catherine, Brandon, Hall, Vegreville Creek and Wetlands Fund, Kevin, Oliver, John, Johansson, Christina, Jared, Hannah, Katy Pye, Brandon, Gwen, Carly, Stephen, Botanical Tours, Moonwort Studios, Liba, Mohsin Kazmi Takes Pictures, doeg, Clifton, Stephanie, Benjamin, Eli, Rachael, Plant By Design, Philip, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Mark, Rens, Bendix, Irene, Holly, Caitlin, Manuel, Jennifer, Sara, and Margie.

Ep. 152 - Forests, Ozone, and Earth's Largest Mass Extinction

The End-Permian Extinction occurred some 252 million years ago. It has been referred to as "the day the earth nearly died.  It is estimated that the world lost up to 96% of all marine species, 70% of terrestrial vertebrate species, and 83% of all insect genera alive during that time. Life on this planet took much longer to rebound than at any other time in history. Though we know volcanism played a roll in this extinct, paleontologists have always been looking for a mechanism that could connect the two. Thanks to Jeff Benca and others, we now have an idea. In this episode we talk about how weakening of the ozone layer led to massive forest declines around the globe. This in turn had serious ramifications for the rest of the biosphere. This work not only fills a big gap in our prehistoric history, it tells an alarming tale for our future if we continue to disregard habitat destruction. This is one episode you don't want to miss.

Ep. 110 - Resolving Ice Age Ecosysems: Using the Past to Understand the Future

Trying to piece together an accurate picture of past ecosystems requires a lot of patience and attention to detail. That is why I am so amazed by the work of today's guest. Joining us is paleoecologist Dr. Jacquelyn Gill to talk about her work on ice age ecology. The clues she uses to tell the story of these systems are surprisingly small but incredibly useful. What's more, her work can help us better understand how ecosystems are going to change as man-made climate change rages on. This is one episode you don't want to miss! This episode was produced in part by Mark, Allen, Desiree, Sienna & Garth, Laura, Margie, Troy, Sara, Jennifer, Christopher, Manuel, Daniel, John, Rosanna, and Mary Jane.

Ep. 52 - Flower Phenology: A Story of Tradeoffs

Being sessile organisms, plants have to be able to cope with changes in their environment in unique ways. One of the major challenges plants face is knowing when to flower. Whereas some species stick to steadfast schedules, others have evolved some flexibility to cope with their stochastic surroundings. Dr. Emily Austen is interested in the evolution and maintenance of flowering strategies. She is also undertaking a fascinating citizen science project involving trout lily pollen color. With spring well underway, this is a timely episode you won't want to miss.

Ep. 47 - Pollinators and Parentage

I have always thought of pollination as rather straight forward - a pollinator visits a plant, picks up pollen, and deposits that pollen on its next visit. As it turns out, it's not that simple. To find out more about the complexities of pollination, I called up Dr. Randy Mitchell from the University of Akron in Ohio. His research is going to blow your mind. What to us seems like the perfect mutualism turns out to be more like a dark alley transaction in which each party is trying to get as much from the other without giving too much in return. This episode was produced in part by Allan Pisula of Kinosha, Wisconsin.
