Book Description
The best available reference on amber is now revised and updated. Dr. Rice's Amber presents a comprehensive reference for the general collector, carver, or the scientist. She begins with the history of amber, which moves from the Stone Age through archaeological finds, ancient writings and medieval chronicles, and then on to explore the scientific studies of amber and how it attained commercial value. Amber provides information on the cultural changes relating to amber jewelry plus the mystical powers attributed to the gem. It is updated to include information on mining in the Baltic areas as well as new information on DNA Coding.

Book Description
From the Arctic to South Africa - one finds them everywhere: Ants. Making up nearly 15% of the entire terrestrial animal biomass, ants are impressive not only in quantitative terms, they also fascinate by their highly organized and complex social system. Their caste system, the division of labor, the origin of altruistic behavior and the complex forms of chemical communication makes them the most interesting group of social organisms and the main subject for sociobiologists. Not least is their ecological importance: Ants are the premier soil turners, channelers of energy and dominatrices of the insect fauna. TOC:The importance of ants.- Classification and origins.- The colony life cycle.- Altruism and the origin of the worker caste.- Colony odor and kin recognition.- Queen numbers and domination.- Communication.- Caste and division of labor.- Social homeostasis and flexibility.- Foraging and territorial strategies.- The organization of species communities.- Symbioses among ant species.- Symbioses with other animals.- Interaction with plants.- The specialized predators.- The army ants.- The fungus growers.- The harvesters.- The weaver ants.- Collecting and culturing ants.- Glossary.- Bibliography.- Index.

Book Description
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. Cataglyphis 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 Cataglyphis 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, Rüdiger Wehner and his collaborators have devised elegant experiments to unmask how they do it. Through a lively and lucid narrative, Desert Navigator 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 Earth’s 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. Desert Navigator brings to light the marvelous capacity and complexity found in these remarkable insects and shows us how mini brains can solve mega tasks.
