Summary

Microbes are everywhere and studying them isn't always easy, but microbial ecology is a vitally important field. Microbes influence the world around them in numerous ways and trying to understand how they do that with plants is where people like Dr. Leonora Bittleston come in. Join us as we explore the leaf microbiomes of sagebrush (Artemisia tridentata) and various species of pitcher plants (Sarracenia, Nepenthes, and Cephalotus) and learn just how fractal community ecology truly is! This episode was produced in part by April, Dana, Lilith, Sanza, Eva, Yellowroot, Wisewren, Nadia, Heidi, Blake, Josh, Laure, R.J., Carly, Lucia, Dana, Sarah, Lauren, Strych Mind, Linda, Sylvan, Austin, Sarah, Ethan, Elle, Steve, Cassie, Chuck, Aaron, Gillian, Abi, Rich, Shad, Maddie, Owen, Linda, Alana, Sigma, Max, Richard, Maia, Rens, David, Robert, Thomas, Valerie, Joan, Mohsin Kazmi Photography, Cathy, Simon, Nick, Paul, Charis, EJ, Laura, Sung, NOK, Stephen, Heidi, Kristin, Luke, Sea, Shannon, Thomas, Will, Jamie, Waverly, Brent, Tanner, Rick, Kazys, Dorothy, Katherine, Emily, Theo, Nichole, Paul, Karen, Randi, Caelan, Tom, Don, Susan, Corbin, Keena, Robin, Peter, Whitney, Kenned, Margaret, Daniel, Karen, David, Earl, Jocelyn, Gary, Krysta, Elizabeth, Southern California Carnivorous Plant Enthusiasts, Pattypollinators, Peter, Judson, Ella, Alex, Dan, Pamela, Peter, Andrea, Nathan, Karyn, Michelle, Jillian, Chellie, Linda, Laura, Miz Holly, Christie, Carlos, Paleo Fern, Levi, Sylvia, Lanny, Ben, Lily, Craig, Sarah, Lor, Monika, Brandon, Jeremy, Suzanne, Kristina, Christine, Silas, Michael, Aristia, Felicidad, Lauren, Danielle, Allie, Jeffrey, Amanda, Tommy, Marcel, C Leigh, Karma, Shelby, Christopher, Alvin, Arek, Chellie, Dani, Paul, Dani, Tara, Elly, Colleen, Natalie, Nathan, Ario, Laura, Cari, Margaret, Mary, Connor, Nathan, Jan, Jerome, Brian, Azomonas, Ellie, University Greens, Joseph, Melody, Patricia, Matthew, Garrett, John, Ashley, Cathrine, Melvin, OrangeJulian, Porter, Jules, Griff, Joan, Megan, Marabeth, Les, Ali, Southside Plants, Keiko, Robert, Bryce, Wilma, Amanda, Helen, Mikey, Michelle, German, Joerg, Cathy, Tate, Steve, Kae, Carole, Mr. Keith Santner, Lynn, Aaron, Sara, Kenned, Brett, Jocelyn, Ethan, Sheryl, Runaway Goldfish, Ryan, Chris, Alana, Rachel, Joanna, Lori, Paul, Griff, Matthew, Bobby, Vaibhav, Steven, Joseph, Brandon, Liam, Hall, Jared, Brandon, Christina, Carly, Kazys, Stephen, Katherine, Manny, doeg, Daniel, Tim, Philip, Tim, Lisa, Brodie, Bendix, Irene, holly, Sara, and Margie.
