Author and sailor David Barrie voyaged around the globe and through scientific literature to learn about the awe-inducing and still mysterious navigational powers of animals. Barrie writes of mysteries such as how birds employ “map and compass” type navigation, how Box jellyfish use some of their twenty-four eyes to keep track of trees and other above-water landmarks, how sweat bees can detect and find their ways home using single photons of light, and how Sahara desert ants measure their turns and count their steps in a process humans call “dead reckoning” — in addition to relying on visual landmarks, patterns of light invisible to the human eye, wind micro-vibrations, scent, optic flow, and the earth’s magnetic field. Animals’ navigational feats reveal an extraordinary awareness of the environment around them — a form of perception that is often far different from our own. In his new book, Supernavigators, Barrie describes the navigational intelligences of other species, which often exceed our wildest imaginations, and issues a call for humans, too often “blinded by vision,” to better respect and celebrate these animals’ abilities in an era when human behavior is increasingly impeding them.
In the spring of 1963, when our guest Dr. Thomas Seeley was not quite 11 years old, he lived — as he still does today — in a wooded stream valley just east of Ithaca, New York. One day, he heard a loud buzzing sound and saw a bread-truck-sized cloud of honey bees swarming an ancient black walnut tree near his family’s house. From a distance, he watched as the bees took up residence in a cavity in the tree. Why, he wondered, did the bees choose that particular tree cavity for their home? Humans have lived with bees for our entire existence as a species, but the vast majority of studies have focused on how bees live in managed colonies, whether the clay cylinders used to keep bees in the Iron Age or the white boxes of neighborhood beekeepers. But here, in the black walnut tree, were wild bees — living without human supervision or human understanding. Their lives present great mysteries. That 11-year-old grew up to become the world’s leading authority on honey bees, and a magnificently gifted writer about their worlds. Dr. Seeley joins us to discuss his research about wild honey bees’ behavior, social lives and ecology, and his new book: “The Lives of Bees: The Untold Story of the Honeybee in the Wild.”
A concert pianist-turned-entomologist and bedbug expert, Dr. Gale Ridge is an insect detective. She solves mysteries and helps thousands of perplexed, struggling people with all varieties of bug problems — from bedbugs to agricultural pests to imaginary bugs that infest our consciousness. Dr. Ridge speaks about her sleuthing and how she brokers peace between the humans that walk in her door at the Connecticut Insect Inquiry Office and the tiny segmented animals we’ve learned to fear.
Termites outweigh humans ten to one. If they went on strike, ecological chaos would ensue. We speak with science writer Lisa Margonelli, author of the new book Underbug: An Obsessive Tale of Termites and Technology, about the questions these small creatures raise about technology, power, morality, and the nature of scientific progress.
