All organisms require nitrogen to live and grow. The movement of nitrogen between the atmosphere, biosphere, and geosphere in different forms is described by the nitrogen cycle. This book is an activity of the COST 856 Action on Denitrification. It covers all aspects of the N-cycle: chemistry, biology (enzymology, molecular biology), physics, applied aspects (greenhouse effect, N-pollution problems, practices in farming, in waste-water treatment, and more). In this book, leading editors offer the latest research available on dentrification (reduction of nitrates or nitrites commonly by bacteria- as in soil). * Provides details on denitrification and its general role in the environment * Offers latest research in N-Cycle and its reactions * Discusses impacts on various environments: agriculture, wetlands, plants, waste-water treatment and more * The only book available in the field since the last 20 years * Contains 27 chapters written by internationally highly recognized experts in the field * Covers all modern aspects, emphasizes molecular biology and ecology * Written in an easily understandable way

SummaryThis paper discusses recent scientific research that has shifted the terms of the debate about the respective roles of nature and nurture in shaping behavior. The research includes literature in the areas of biology, psychometrics, evolutionary psychology, and behavioral genetics. The paper then shows the relevance of this literature for ongoing concerns about mass immigration in developed countries. The literature has implications not only for the personal success of the immigrants, but rates of social dependency and the outlook for political and social cooperation in increasingly diverse societies. Efforts to remediate IQ deficits or behavioral problems in some immigrant groups are seen to be problematic.

The traditional emphasis on human nature as the foundation of politics needs to be reexamined from the perspective of contemporary biology. Because biological processes operate independently on the individual, the social group, and the species, an evolutionary approach to both observational research and cost-benefit analysis does not entail reductionism. Selfishness and altruism, participation in social groups, languages and cultures, and the rise and fall of centralized states can all be illuminated by empirical evidence and theories in the life sciences. For political philosophy, a new "naturalism" points to a return to the Aristotelian view that values or standards of judgment have rationally intelligible foundations, thereby challenging the relativist or nihilistic orientation that has characterized most contemporary thought.

Mathematical Models for Society and Biology, 2e, is a useful resource for researchers, graduate students, and post-docs in the applied mathematics and life science fields. Mathematical modeling is one of the major subfields of mathematical biology. A mathematical model may be used to help explain a system, to study the effects of different components, and to make predictions about behavior. Mathematical Models for Society and Biology, 2e, draws on current issues to engagingly relate how to use mathematics to gain insight into problems in biology and contemporary society. For this new edition, author Edward Beltrami uses mathematical models that are simple, transparent, and verifiable. Also new to this edition is an introduction to mathematical notions that every quantitative scientist in the biological and social sciences should know. Additionally, each chapter now includes a detailed discussion on how to formulate a reasonable model to gain insight into the specific question that has been introduced. Offers 40% more content - 5 new chapters in addition to revisions to existing chapters Accessible for quick self study as well as a resource for courses in molecular biology, biochemistry, embryology and cell biology, medicine, ecology and evolution, bio-mathematics, and applied math in general Features expanded appendices with an extensive list of references, solutions to selected exercises in the book, and further discussion of various mathematical methods introduced in the book.

There has been much attention devoted in recent years to the question of whether our moral principles can be related to our biological nature. This collection of essays focuses on the connection between biology, in particular evolutionary biology, and foundational questions in ethics. The book asks such questions as whether humans are innately selfish, and whether there are particular facets of human nature that bear directly on social practices. The volume is organised historically beginning with Aristotle and covering such major figures as Hume and Darwin down to the present and the work of Harvard sociobiologist, E. O. Wilson. This is the first book to offer this historical perspective on the relation of biology and ethics, and has been written by some of the leading figures in the history and philosophy of science, whose work stands very much at the cutting edge of these disciplines

Symbioses and Stress examines how organisms in tight symbiotic associations cope with abiotic and biotic stress. Presenting new findings on symbioses by experts and leading scholars in the field, this volume complements courses and lectures in biology and genetics.
