The Bat, the Blossom and the Biologist with Donna Howell
There is in Arizona a bat that flies thousands of miles each spring to feed on the flowers of a plant that blooms only once in 25 years - and then dies. Last summer Q.E.D went to the Sonoran Desert in pursuit of this curious but intimate relationship - for it is a trading of food for sex: the bat gets the food and the flower gets pollinated in exchange.
For more than a decade, biologist Donna Howell has been unravelling how two such unlikely partners make the most of each other.
