From subarctic tundra to equatorial rainforest, deep in the soil and at the tip of the highest tree, ants are found the world over. This book, by the world’s leading ant taxonomist, offers a definitive guide for identifying these ubiquitous insects.

Barry Bolton provides identification keys to all the living ant subfamilies and genera, presented in alphabetical order and separated by zoogeographical region. Designed for professional and amateur myrmecologists alike, this guide is as accessible as it is comprehensive, including information on the function and use of identification keys, instructions for preparing specimens for examination, and an illustrated glossary of morphological terms. Over 500 scanning electron microscope photographs illustrate the taxonomic keys.

Bolton introduces each subfamily with a diagnosis of the group, followed by synoptic classifications of all genera within each subfamily, notes on broad distribution, and a list of references to all species-rank publications useful to identification. He also provides a short summary of the extinct subfamilies and includes a checklist of every name ever proposed in the classification of ants, from the rank of family down to subgenus, showing the current status and usage of each.

An updated and exhaustively expanded revision of the taxonomic keys found in Hölldobler and Wilson’s The Ants, Bolton’s identification guide takes its place alongside that landmark work as the foundation for the study of ants for many years to come.

Why would a grown man chase hornets with a thermometer, paint whirligig beetles bright red, or track elephants through the night to fill trash bags with their prodigious droppings? Some might say—to advance science. Bernd Heinrich says—because it’s fun.

Heinrich, author of the much acclaimed Bumblebee Economics, has been playing in the wilds of one continent or another all his life. In the process, he has become one of the world’s foremost physiological ecologists. With In a Patch of Fireweed, he will undoubtedly become one of our foremost writers of popular science.

Part autobiography, part case study in the ways of field biology, In a Patch of Fireweed is an endlessly fascinating account of a scientist’s life and work. For the author, it is an opportunity to report not just his results but the curiosity, humor, error, passion, and competitiveness that feed into the process of discovery. For the reader, it is simply a delight, a rare chance to share the perceptions of an unusual mind fully in tune with the inner workings of nature. Before his years of research in the woodlands and deserts of North America, the New Guinea highlands, and the plains of East Africa, Heinrich had a sense of the wild that few people in this century can know. He tells the whole story, from his refugee childhood hidden in a German forest, eating mice fried in boar fat, to his ongoing research in the woods surrounding his cabin in Maine.

Early birds and night owls are born, not made. Sleep patterns may be the most obvious manifestation of the highly individualized biological clocks we inherit, but these clocks also regulate bodily functions from digestion to hormone levels to cognition. Living at odds with our internal timepieces, Till Roenneberg shows, can make us chronically sleep deprived and more likely to smoke, gain weight, feel depressed, fall ill, and fail geometry. By understanding and respecting our internal time, we can live better.

“Internal Time is a cautionary tale—actually a series of 24 tales, not coincidentally. Roenneberg ranges widely from the inner workings of biological rhythms to their social implications, illuminating each scientific tutorial with an anecdote inspired by clinical research...Written with grace and good humor, Internal Time is a serious work of science incorporating the latest research in chronobiology...[A] compelling volume.”
—A. Roger Ekirch, Wall Street Journal

“This is a fascinating introduction to an important topic, which will appeal to anyone who wishes to delve deep into the world of chronobiology, or simply wonders why they struggle to get a good night’s sleep.”
—Richard Wiseman, New Scientist

In three volumes, historian Jole Shackelford delineates the history of the study of biological rhythms—now widely known as chronobiology—from antiquity into the twentieth century. Perhaps the most well-known biological rhythm is the circadian rhythm, tied to the cycles of day and night and often referred to as the “body clock.” But there are many other biological rhythms, and although scientists and the natural philosophers who preceded them have long known about them, only in the past thirty years have a handful of pioneering scientists begun to study such rhythms in plants and animals seriously. Tracing the intellectual and institutional development of biological rhythm studies, Shackelford offers a meaningful, evidence-based account of a field that today holds great promise for applications in agriculture, health care, and public health. Volume 1 follows early biological observations and research, chiefly on plants; volume 2 turns to animal and human rhythms and the disciplinary contexts for chronobiological investigation; and volume 3 focuses primarily on twentieth-century researchers who modeled biological clocks and sought them out, including three molecular biologists whose work in determining clock mechanisms earned them a Nobel Prize in 2017.

The search for effective immunization against pneumonia was a principal avenue of investigation before the advent of The search for effective immunization against pneumonia was a principal avenue of investigation before the advent of antibiotics made such an effort appear unnecessary. Recently, however, the limitations of antibiotic therapy have become increasingly evident, and interest has been renewed in many of the threads of research which have all but lain dormant since the 1930s. In 1978, a pneumococcal vaccine was licensed by the F.D.A., merely as evidence of a renaissance in pneumococcal research which is now taking place. We are pleased to be reissuing two classic volumes which provide a unique repository of data amassed prior to the time when penicillin precluded further exhaustive observation of the unmodified infection.

Heffron’s Pneumonia is a compilation and analysis of all aspects of pneumococcal disease, including the distribution of pneumococcal types, the pathology of pneumonia, its epidemiology, symptoms, signs, complications, diagnosis, prognosis, and immunology. With a complete cross-reference index and an extensive bibliography, Heffron’s book is still the definitive work on pneumococcal infections.

White’s Biology of Pneumococcus contains the wealth of information acquired in the first six decades following the discovery of the pneumococcus. With a bibliography drawing together some 1593 papers, White’s volume is of unquestionable significance as a historical record and the basis for further study.

“The greenhouse effect is us, and it is specifically us in the Western world.” This is one of the messages at the beginning of Anita Gordon and David Suzuki’s startling view of our future on Earth. More than any other time in history, the 1990s have marked a turning point for human civilization. Not only are we facing ecological disasters that will affect our ability to survive, but the crisis is forcing us to reexamine the entire value system that has governed our lives for the past two thousand years.

Gordon and Suzuki warn us of the transition we will need to make if we are to arrive safely in the next century. More than a book on the environment, this is a book about us as a species: our shortsightedness, our failure to read the warnings, our inability to grasp the significance of our actions-and the tough decisions we have to make in order to save ourselves.

The power of the book lies in the consensus of the many voices, those of scientists and other scholars, that speak through it. The components of our predicament—global warming, soil erosion, acid rain, species depletion, ozone damage, rainforest destruction, overpopulation—are quantified with authority. And never before has such a strong consensus been expressed in a single warning. The message we receive is that our actions are taking place in a political and economic world that demands radical change.

In an effort to counteract this blueprint for disaster, Gordon and Suzuki present a resounding rebuttal of technological optimism and the belief that continued economic growth is a prerequisite for environmental reform. The intellectual fog of sustainable development is incisively dispelled, and in its place the authors suggest practical contributions that individuals as well as governments can make toward creating a “conserver society.”
