Ein gigantischer Komet aus den Tiefen des Alls ist auf Kollisionskurs mit der Erde. Er wird zu einem denkbar späten Zeitpunkt entdeckt. Nur wenig Zeit verbleibt der Menschheit, um Gegenmaßnahmen zu ergreifen. Unter dem enormen Zeitdruck ist die Abwehr zum Scheitern verurteilt, die benötigte Technik ist noch nicht ausgereift. Es kommt, was kommen
muss: Die Katastrophe nimmt ihren Lauf. Mit der Kraft von 100 Millionen Megatonnen TNT schlägt das Himmelsgeschoss auf der Erde ein. Ganze Kontinente werden verwüstet, weltweite Feuersbrünste entfacht. Monatelang wird die Erde in eine dunkle Wolke aus Schutt und Asche gehüllt, eine globale Eiszeit folgt. Zahlreiche Tier und Pfl anzenarten sterben für immer aus und auch die Menschheit kämpft ums Überleben.

Business cycles are both important and, despite a large amount of economic research, still incompletely understood. In these notes the author will describe how to use standard neoclassical theory to explain business cycle fluctuations.

Plant hormones play a crucial role in controlling the way in which plants grow and develop. While metabolism provides the power and building blocks for plant life, it is the hormones that regulate the speed of growth of the individual parts and integrate them to produce the form that we recognize as a plant.
This book is a description of these natural chemicals: how they are synthesized and metabolized, how they act at both the organismal and molecular levels, how we measure them, a description of some of the roles they play in regulating plant growth and development, and the prospects for the genetic engineering of hormone levels or responses in crop plants.. This is the third edition of the highly acclaimed text/monograph last published in 1995 under the title

A photographic paperback series designed to introduce the fascinating world of animals and how they develop. In this informative and highly visual series, appealing step-by-step photography allows children to see a butterfly emerge from its cocoon and spread its wings, or see what happens when an egg hatches and a chick emerges. Each book comes with a sticker sheet packed with cute images of the animals featured in the book.

This reference work explains the grammar and syntax of botanical Latin, and covers the roots and origins of Latin and latinised geographical names, colour terms, symbols and abbreviations, diagnoses and descriptions, and the formation of names and epithets.

Sphingolipids are fundamental to the structures of cell membranes, lipoproteins, and the stratum cornea of the skin. Many complex sphingolipids as well as simpler sphingoid bases and derivatives are highly bioactive as extra- and intracellular regulators of growth, differentiation, migration, survival, senescence, and numerous cellular responses to stress. This book provides many examples of exciting new developments in sphingolipid biology/sphingolipidology that are changing our understanding of how multicellular organisms grow, develop, function, age, and die. Key areas addressed include sphingolipid biosynthesis, transport and membrane organization/lipid rafts; genetic approaches to understanding the roles of membrane sphingolipid biosynthesis; sphingolipid metabolism, specific G protein-coupled receptors (GPCRs), and signal transduction; and sphingolipid-associated disease and drug development.

Find out about the basic chemistry, biology, physiology, and ecology of plant nutrition and how these topics relate to us on a personal, social, and global scale.

Presenting plants as photosynthetic machines, this book follows the flow of energy and carbon through the natural processes of photosynthesis and respiration, spotlighting the role plants play in balancing the global carbon budget.

An investigation into managing fish stocks in the North Atlantic, focusing on: how to avoid institutional inertia and encourage flexible responses to the changing environment of fishing; and how to cope with pressures for integrated fisheries management based on an ecosystem approach. These and other issues are examined through contributions from scientists, economists, sociologists, political scientists and representatives of the fishing industry from around the North Atlantic region.

Knowing that is one thing. Being able to do something about it -especially in Pennsylvania, where deer hunting traditions are asdeeply rooted as 100-year-old white oak - is something else. A numberof people, some Game Commission officials included, say they deerherd has been mismanaged for 80 years. That must change, they say,if deer populations are to finally be brought into balance withtheir habitat and if hunting as we know it is to survive.

Birch confronts the impression conveyed by modern biology that it explains all that is to be known about life. While biology has had a superb history of explaining the objective aspects of life, it has been unable to deal with subjective phenomena. Birch has provided an optimistic rethinking of both science and religion.

The author recounts earlier investigations Klimley made trying to dis-cover the connections among seamounts, the Earth's magnetic field, and the sharks' migratory patterns in the sea, showing just how scientists put laboratory theses to the proof in the field. A fascinating record of re-search and investigation, this inviting book is larded with numerous dramatic color pho-tos.

Animal rights extremists argue that eating meat is murder and that pets are slaves. This compelling reappraisal of the human-animal bond, however, shows that domestication of animals is not an act of exploitation but a brilliantly successful evolutionary strategy that has benefited humans and animals alike.

This book really made the mid-Atlantic region come to life for me! I wanted to grab a day pack and head out for a day hike. I'm sure that any serious nature lover would really enjoy this book.

This accessible account of the Human Genome Project is as much about the politics, economics, and personalities as it is about the science of this $3 billion, 15-year project to map the 100,000 chromosome sequences of the human genome. However, more discussion of the potential clinical implications and controversies surrounding the decision to map the entire genome, including sequences with no currently known purpose, would have been helpful. Cook-Deegan, Executive Director for the Biomedical Ethics Advisory Committee when funding was cut, is occasionally an intrusive narrator, concerned about his own career prospect.
