Upon seeing an adorable Koala sitting on an eucalyptus branch in Australia, few would expect the beloved marsupial to emit a booming bellow to alert potential mates or rivals of its presence. But this powerful roar is just one of koalas’ many surprises, which delight and astonish in Australian biologist Danielle Clode’s new book, “Koala: A Life in the Trees.” Clode explores the enigmatic koala’s 24 million years-long saga of evolutionary adaptations, conservation triumphs, and endangerment catastrophes, and the prospects for their future following the 2019 bushfires that devastated Australia’s ..read more

Most books on puppies are dog-improvement manuals, guiding readers ‘How to Raise the Perfect Dog’ or how to achieve ‘Perfect Puppy in 7 Days.’ Alexandra Horowitz’s profound and totally delightful new book is not that type of book. It’s an unprecedented look at the complex, chaotic, fascinating, and often hilarious journeys of puppies becoming themselves. “Instead of following an instruction manual for a puppy, I wanted to follow the puppy,” she writes. The Swiss psychologist Jean Piaget famously watched his own kids grow into adults as both a parent and a scientist. His observations of his kid ..read more

Grazing peacefully through shallow waterways, the Florida manatee is one of the state’s most beloved creatures. Due to a multitude of compounding, human-caused crises, the last couple years have been some of the deadliest on record for manatees. Years of worsening water quality from Florida’s unfettered agricultural pollution and real estate development have resulted in increased toxic algae blooms that block sunlight from reaching the seagrass meadows upon which the manatees depend. In 2021, Florida’s manatees died in massive numbers, with a record 1,100 manatees – more than 12 percent of the ..read more

The fossil record acts as both a memorial to life’s spectacular possibilities and as a warning to humanity about how fast dominance can become forgotten history, according to our guest, Scottish paleobiologist Dr. Thomas Halliday. Halliday’s research investigates long-term patterns in the fossil record, particularly in mammals. In his magnificent and daring new book “Otherlands: A Journey through Earth’s Extinct Worlds,” Halliday translates cutting-edge science into vivid portraits of sixteen fossil sites and their inhabitants extending back 550 million years. We speak with Halliday about his ..read more

Amid the cataclysms of the Anthropocene, an era defined by humans’ attempts to control the natural world, it’s easy to forget that we remain as subject as ever to the ecological laws that govern living things. Like the laws of physics, paying attention to our planet’s biological laws empowers us to understand how the world works and to make predictions about the outcomes of our actions. In his new book, A Natural History of the Future, ecologist Rob Dunn warns that continuing to ignore these laws will cause us to fail again and again in our attempts to build a sustainable future for our specie ..read more

In 1995, the U.S. government took unprecedented actions to restore the wolf population of Yellowstone National Park, which it had brutally destroyed seventy years prior. More than thirty wolves from multiple packs were captured in Canada, transported to the park, and released in a grand experiment that would become the most successful wildlife reintroduction effort in history. Our guest, the legendary wolf expert Rick McIntyre, has dedicated his life to those wolves. For the past 26 years, he has observed the park’s wolves nearly every single day, accumulating more than 100,000 sightings. Afte ..read more

From tiny cowries to giant clams, seashells have gripped human imaginations since time immemorial. In her magnificent new book, The Sound of the Sea, journalist Cynthia Barnett tells the epic history of humanity’s interactions with shells and the soft-bodied animals who make them. These stories of how we have treasured, traded, plundered, and coveted shells reveal much about who we are and who we’ve been, both good and bad. Barnett’s deep research ranges from the awe-inspiring “great cities of shell” of the Calusa people in Florida, to the use of cowrie shells as currency in the Atlantic slave ..read more

Most of us land-lubbers assume that light-making among ocean creatures is an exotic and rare phenomenon. But that’s wrong. The majority of animals in the ocean, which means the majority of animals on the planet, are capable of making light. From top to bottom, the ocean is teeming with unforgettably beautiful and extraordinarily diverse light shows made by animals that we’re only beginning to understand, from deep-sea shrimp that distract predators by spewing glowing mucus to squids that backlight their body tissue in flickering patterns that seem to coordinate group hunting. In this episode ..read more

Hedgehogs, despite being consistently voted the most beloved mammal in the United Kingdom, have suffered great population losses as industrial agriculture and other human impacts destroy their hedgerow habitats. Our latest guest, Hugh Warwick, has studied, celebrated, written about, and fought to protect hedgehogs for more than 30 years, leading a groundswell of local and individual action to protect the small animal. We spoke with Warwick about his role as the spokesperson for the British Hedgehog Preservation Society, his writings on the impact of manmade lines on the ability of wild animals ..read more
