Description of  Desert Navigator: The Journey of an Ant

Winner of the Association of American Publishers PROSE Award for Excellence in Biological and Life Sciences A world-renowned researcher of animal behavior reveals the extraordinary orienteering skills of desert ants, offering a thrilling account of the sophisticated ways insects function in their natural environments. desert ants are agile ultrarunners who can tolerate near-lethal temperatures when they forage in the hot midday sun. But it is their remarkable navigational abilities that make these ants so fascinating to study. Whether in the Sahara or its ecological equivalents in the Namib Desert and Australian Outback, the navigators can set out foraging across vast expanses of desert terrain in search of prey, and then find the shortest way home. For almost half a century, Rdiger Wehner and his collaborators have devised elegant experiments to unmask how they do it. Through a lively and lucid narrative, offers a firsthand look at the extraordinary navigational skills of these charismatic desert dwellers and the experiments that revealed how they strategize and solve complex problems. Wehner and his team discovered that these insect navigators use visual cues in the sky that humans are unable to see, the Earths magnetic field, wind direction, a step counter, and panoramic snapshots of landmarks, among other resources. The ants combine all of this information to steer an optimal course. At any given time during their long journey, they know exactly where to go. It is no wonder these nimble and versatile creatures have become models in the study of animal navigation. brings to light the marvelous capacity and complexity found in these remarkable insects and shows us how mini brains can solve mega tasks.
