  • Reviews for Richard Conniff’s Books

    Every Creeping Thing: True Tales of Faintly Repulsive Wildlife: “Conniff is a splendid writer–fresh, clear, uncondescending, and with never a false step; one can’t resist quoting him.” (NY Times Book Review)

    The Species Seekers:  Heroes, Fools, and the Mad Pursuit of Life on Earth by Richard Conniff is “a swashbuckling romp” that “brilliantly evokes that just-before Darwin era” (BBC Focus) and “an enduring story bursting at the seams with intriguing, fantastical and disturbing anecdotes” (New Scientist). “This beautifully written book has the verve of an adventure story” (Wall St. Journal)

    Swimming with Piranhas at Feeding Time by Richard Conniff  is “Hilariously informative…This book will remind you why you always wanted to be a naturalist.” (Outside magazine) “Field naturalist Conniff’s animal adventures … are so amusing and full color that they burst right off the page …  a quick and intensely pleasurable read.” (Seed magazine) “Conniff’s poetic accounts of giraffes drifting past like sail boats, and his feeble attempts to educate Vervet monkeys on the wonders of tissue paper will leave your heart and sides aching.  An excellent read.” (BBC Focus magazine)

Behind the Scenes at The Truman Show for Ants

Posted by Richard Conniff on July 18, 2013


My new post for TakePart:


Even in the arcane world of ant behavior, the right headline can make all the difference. Back in May, Danielle Mersch and her colleagues at the University of Lausanne in Switzerland published an article in Science.They got very little attention for it, perhaps because the headline wasn’t exactly an attention-grabber: “Tracking Individuals Shows Spatial Fidelity Is a Key Regulator of Ant Social Organization.”

But a new article, just published in Current Biology, gives Mersch’s work the spin it clearly deserves. Under the headline “Animal Behavior: The Truman Show for Ants,” the authors describe how the system Mersch’s team devised to track the second-by-second movements of every individual in an ant colony resembles the popular 1998 film starring Jim Carrey. In that film, Truman Burbank, played by Carrey, belatedly discovers that his entire life has been a reality show produced and managed for broadcast.

At Mersch’s laboratory in Lausanne, the lives being recorded take place in a row of Styrofoam boxes, each about the size of a bar refrigerator, lined up on a counter. A computer precisely controls temperature and humidity inside each box, where a colony of about 150 carpenter ants (Camponotus fellah) goes back and forth between daytime and nighttime compartments. Mersch has 11 separate colonies under watch at the moment. Like Truman before he wakes up, the ants are apparently oblivious that the outside world is looking in, though every ant carries a barcode-like placard on its back, for automated identification, and an overhead camera … to read the rest of this post click here.
