Constant Wonder

What if protecting humans is the key to protecting wildlife? In this episode, Dr. Gladys Kalema-Zikusoka tells host Marcus Smith how people living near African nature preserves can unknowingly pass illnesses to nearby mountain gorillas—and how she's working with local communities to shield these endangered animals from disease and habitat loss.

As Uganda's first wildlife veterinarian, Kalema-Zikusoka pioneered the use of "One Health" in gorilla conservation—an approach that treats human, animal, and environmental health as interconnected, rather than separate concerns. By investing in the health and economic security of nearby communities, she keeps gorillas healthy too. The payoff is a thriving gorilla tourism industry that benefits the entire country.

Guest: Dr. Gladys Kalema-Zikusoka, founder and CEO of Conservation Through Public Health and author of "Walking with Gorillas: The Journey of an African Wildlife Vet"

Flowers, believe it or not, are nature's greatest revolutionaries. In this episode of Constant Wonder, biologist David George Haskell and host Marcus Smith discuss how flowers turned enemies into allies and used ultra-precise adaptations to survive an intensely competitive natural world.

By exploring the floral connections that draw him closer to his mother and great-great-grandfather, David also examines how flowers have changed in just a few short decades. He makes the case for following a single bloom's growth and decay over the course of several months, and describes the benefits of keeping a floral diary—an easy way for anyone to become more attentive to the subtle turning of the seasons.

They are like street musicians, busking with words instead of instruments. Typewriter poets Kathleen Rooney and Allison Fragakis share with Constant Wonder's Tennery Taylor how they write poems-on-demand for complete strangers.

Whether at a farmer's market, tucked between the stacks at a library, or as entertainment at a wedding, typewriter poets surprise customers with a keepsake that reflects unexpected insight into a stranger's life. (Or maybe it's a poem about a burrito! These poems don't have to be serious.) Kathleen Rooney and Allison Fragakis share their creativity and love of community through impromptu poetry sessions on typewriters.

Guests:
Kathleen Rooney, co-founder of "Poems While You Wait"; English professor at DePaul University; author of "Man Overboard!" and other books https://kathleenrooney.com/

Allison Fragakis, songwriter, author, artist, and poet. Her album "Pass the Dream" is available August 21, 2026 https://www.writingallison.com/

Jeremy Jones has loved exploring the Blue Ridge Mountains since childhood, and despite his world travels, his identity as a "mountain person" always brought him home. His family has lived in Henderson County for five generations—so when Hurricane Helene sent the river rising toward his old farmhouse, it threatened more than a house. In this episode of Constant Wonder, Jeremy joins host Marcus Smith to share what it took to rebuild, and how the experience reconnected him to his neighbors, his family, and a history in these mountains that runs deeper than he'd realized.

Guest: Jeremy Jones is a professor of English Studies at Western Carolina University, and the author of books "Cipher: Decoding My Ancestor’s Scandalous Secret Diaries" (Blair, 2025) and "Bearwallow: A Personal History of a Mountain Homeland" (Blair, 2014).

Snakes. Scorpions. Sharks. From a young age, Rachel Graham has always been interested in marginalized, "scary" animals. In this episode of Constant Wonder, she and host Marcus Smith discuss how she embarked on her quest to change people’s mindsets about sharks—fascinating and threatened creatures that regularly fill her with awe.

From being surrounded by a real-life sharknado to swimming alongside curious whale sharks, Rachel has had many peaceful, once-in-a-lifetime encounters with these megafauna.  As part of her work with the non-profit conservation organization MarAlliance, she partners with local fishermen and coastal communities to protect vulnerable marine wildlife.
