How Fungi Are Breaking The Binary: A Queer Approach To Ecology

As Pride month comes to a close, many people are reflecting on the past, present, and future of the LGBTQIA+ community.

An interdisciplinary group of scientists, researchers, and artists are using queerness as a lens to better understand the natural world, too. It’s a burgeoning field called queer ecology, which aims to break down binaries and question our assumptions of the natural world based on heterosexuality.

For example, there are plenty of examples of same-sex animal pairings in the wild, like penguins, chimps, and axolotls. There are also plants that change sexes, or have a combination of male and female parts, like the mulberry tree.

But perhaps the most queer kingdom of all is fungi. Mushrooms are not easily forced into any type of binary. For example, the Schizophyllum commune, or the split gill mushroom, has 23,000 sexes, making it somewhat of a queer icon in the field of mycology.

SciFri producer Kathleen Davis talks with Patty Kaishian, incoming curator of mycology at the New York State Museum, about how fungi might help us expand our understandings of sexuality, identity, and hierarchy. They also discuss how queer ecology can help people of all sexualities reconnect with the natural world.

Earlier this year, a baby Przewalski’s horse was born at the San Diego Zoo. But this foal isn’t any ordinary foal, he’s a clone. He’s the product of scientists aiming to save his dwindling species using genetics. This endangered horse species once roamed Europe and Asia, but by the 1960, threats like poaching, capture, and military presence drove the horses to extinction in the wild.

Conservationists raced to save this wild horse through captive breeding programs, but with a population so small, there just wasn’t enough genetic diversity to grow a healthy herd. But with careful genetic management, the Przewalski’s horse’s population is now nearly 2,000 horses strong, and this new foal will one day help boost his species’ genetic diversity even more.

Producer Kathleen Davis talks with Dr. Oliver Ryder, conservation geneticist at the San Diego Zoo Wildlife Alliance, about cloning Przewalski’s horse, and how doing so will infuse genetic diversity into the small population.

Then Davis talks with Dr. Sam Wisely, professor of wildlife ecology and conservation at the University of Florida, about how cloning can help other endangered species, like the black-footed ferret, and the ethics involved in cloning.

The story of the CubeSat started with a big problem for one Cal Poly professor.

“It was actually a critical problem for us, but it was a problem that nobody e
