The Ants
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.

Breast Disease
This second updated volume on breast cancer provides a comprehensive overview of its clinical management and current therapies. Updated to reflect the changes in breast cancer staging, the progress in immunotherapy approaches, as well as the latest guidelines for therapies, this book brings readers up to speed with the latest therapeutic regimens in breast cancer and provides an in-depth account of current and new therapeutic approaches. The most important phase III trials, high quality meta-analysis, consensus reports and guidelines are extensively discussed in this new edition and provide the reader with the most up-to-date information. Divided in themed parts, the book examines invasive b...
Developmental Plasticity and Evolution
West-Eberhard is widely recognized as one of the most incisive thinkers in evolutionary biology. This book assesses all the evidence for our current understanding of the role of changes in body plan and development for the process of speciation. The process of evolution is systematically reassessed to integrate the insights coming from developmental genetics. Every serious student of evolution, and a substantial share of developmental biologists and geneticists, will need to take note of this contribution. The timing is clearly ripe for the synthesis that this work will help bring about.
Controlling Light in Optically Induced Photonic Lattices
Discrete periodic structures play an important role in physics, and have opened up an exciting new area of investigation in recent years. Questions relating to the control of light in such structures still represent a major challenge. It is this highly active field that is addressed in the present thesis. Using the model system of a photorefractive nonlinearity that allows one to simultaneously create and control photonic lattices by light, the author obtains a comprehensive picture of the control of nonlinear and quantum optics phenomena in photonic lattices. He describes and demonstrates experimentally for the first time resonant transitions in two-dimensional hexagonal lattices, including Rabi oscillations and Landau-Zener tunneling, as well as the direct control and exploitation of these transitions. A particular highlight of this thesis is the study of soliton-cluster switching and control of Zener tunneling.

Fire Ants
In the early years of the twentieth century, South American fire ants crossed the Caribbean and invaded the shores of the southeastern United States. These imported fire ants quickly found a niche in Gulf Coast fields and lawns, overpowered the native species, and began spreading. In the process they became a notorious pest to some, a beneficial ally to others, and a potential killer to allergy sufferers. As a result, they are among the most intensely studied insects in the world. Near the turn of the millennium the dominant species, the red imported fire ant, finally made its long-feared leap across the hostile western desert into the greener oasis of southern California, where it stood poi...
