Nitrogen Cycling in the Americas : Natural and Anthropogenic Influences and Controls
The rate of creation of reactive nitrogen (NR) on the earth has dramatically increased in the last half century mainly due to the production of N-fertilizer through the Haber-Bosch process, fossil fuel combustion, and the cultivation of plants that fix N from the atmosphere. The anthropogenic production of NR has been especially high in developed countries of the temperate zone, such as the USA and Canada, where severe eutrophication of estuaries and coastal zones, acidification of lakes and streams, loss of biodiversity, and reduced forest productivity have become common environmental problems associated with increasing nitrogen loads to ecosystems. This book presents a series of studies from across the Americas whose aim is to highlight key natural processes that control nitrogen cycling as well as discuss the main anthropogenic influences on the nitrogen cycle in both the tropical and temperate regions of the Americas.
Modelling Environmental Dynamics : Advances in Geomatic Solutions
Modelling environmental dynamics is critical to understanding and predicting the evolution of the environment in response to the large number of influences including urbanisation, climate change and deforestation. Simulation and modelling provide support for decision making in environmental management.
Micrometeorology
This book focuses on atmospheric processes which directly effect human environments within the lowest 100-1000 meters of the atmosphere over regions of only a few kilometers in extent. The book is the English translation of the second edition of the German book "Applied Meteorology – Micrometeorological Methods".
Information and its role in nature
Infromation and Its Role in Nature presents an in-depth interdisciplinary discussion of the concept of information and its role in the control of natural processes. After a brief review of classical and quantum information theory, the author addresses numerous central questions, including: Is information reducible to the laws of physics and chemistry? Does the Universe, in its evolution, constantly generate new information? Or are information and information-processing exclusive attributes of living systems, related to the very definition of life? If so, what is the role of information in classical and quantum physics? In what ways does information-processing in the human brain bring about self-consciousness? Accessible to graduate students and professionals from all scientific disciplines, this stimulating book will help to shed light on many controversial issues at the heart of modern science.
Handbook of mathematics
This guide book to mathematics contains in handbook form the fundamental working knowledge of mathematics which is needed as an everyday guide for working scientists and engineers, as well as for students. Easy to understand, and convenient to use, this guide book gives concisely the information necessary to evaluate most problems which occur in concrete applications. In the newer editions emphasis was laid on those fields of mathematics that became more important for the formulation and modeling of technical and natural processes, namely Numerical Mathematics, Probability Theory and Statistics, as well as Information Processing. For the 5th edition, the chapters "Computer Algebra Systems" and "Dynamical Systems and Chaos" were fundamentally revised, updated and expanded. In the chapter "Algebra and Discrete Mathematics" a section on "Finite Fields and Shift Registers" was added.
From Assessing to Conserving Biodiversity : Conceptual and Practical Challenges
This book despite increasing communication, accelerating policy and management responses, and notwithstanding improving ecosystem assessment and endangered species knowledge, conserving biodiversity continues to be more a concern than an accomplished task. Why is it so? The overexploitation of natural resources by our species is a frequently recognised factor, while the short-term economic interests of governments and stakeholders typically clash with the burdens that implementing conservation actions imply. But this is not the whole story. This book develops a different perspective on the problem by exploring the conceptual challenges and practical defiance posed by conserving biodiversity, namely: on the one hand, the difficulties in defining what biodiversity is and characterizing that “thing” to which the word ‘biodiversity’ refers to; on the other hand, the reasons why assessing biodiversity and putting in place effective conservation actions is arduous.
Evolutionary Stasis and Change in the Dominican Republic Neogene
In practice, however, science is no less susceptible to fads, culture shifts, and pendulum swings than any other realm of human endeavor. This is an especially important feature of science to keep in mind in the present climate of shrinking government funding (at least in prop- tion to the demand) and the resulting susceptibility of individual scientists and entire disciplines to being influenced by the changing priorities of funding agencies (even if, as such agencies maintain, those priorities come ultimately “from the c- munity”). The present volume is in several important respects a testimonial to both the threats and opportunities that such scientific culture swings pose, both for the individual researcher and a wider field. When scientific research in the Dominican Republic Neogene began more than a century ago, paleontology was an essentially descriptive discipline, focused mainly on finding, describing, and documenting the taxa represented in the fossil record, and (especially in invertebrate paleontology) on using these taxa for bi- tratigraphic correlation.
Environmental History of the Rhine-Meuse Delta : An ecological story on evolving human–environmental relations coping with climate change and sea-level rise
This book presents the environmental history of the Delta of the lowland rivers Rhine and Meuse, an ecological story on evolving human–environmental relations coping with climate change and sea-level rise. It offers a combination of in-depth ecology and environmental history, dealing with exploitation of land and water, the use of everything nature provided, the development of fisheries and agriculture, changes in biodiversity of higher plants, fish, birds, mammals and invasive exotics. It is the first comprehensive book written in English on the integrated environmental history of the Delta, from prehistoric times up to the present day. It covers the l- acy of human intervention, the inescapable fate of reclaimed, nevertheless subs- ing and sinking polders, ‘bathtubs’ attacked by numerous floods, reclaimed in the Middle Ages and unwittingly exposed to the rising sea level and the increasing amplitude between high and low water in the rivers. The river channels, constricted and regulated between embankments, lost their flood plains, silted up, degraded and incised. Cultivation of raised bog deposits led to oxidation and compacting of peat and clay, resulting in progressive subsidence and flooding; arable land had to be changed into grassland and wetland. For millennia muscular strength and wind and water powers moulded the country into its basic form. From 1800 onwards, acceleration and scaling up by steam power and electricity, and exponential popu- tion growth, resulted in the erection of human structures ‘fixed forever’, and severe pressure on the environment.
Encyclopedia of Soil Science
The Encyclopedia of Soil Science provides a comprehensive, alphabetical treatment of basic soil science in a single volume. It constitutes a wide ranging and authorative collection of about 160 academic articles covering the salient aspects of soil physics, chemistry, biology, fertility, technology, genesis, morphology, classification and geomorphology.
Deduction, Computation, Experiment : Exploring the Effectiveness of Proof
What is a proof for? What is the characteristic use of a proof as a computation, as opposed to its use as an experiment? What is the relationship between mathematical procedures and natural processes? The essays collected in this volume address such questions from different points of view and will interest students and scholars in several branches of scientific knowledge. Some essays deal with the logical skeleton of deduction, others examine the interplay between natural systems and models of computation, yet others use significant results from the natural sciences to illustrate the character of procedures in applied mathematics. Focusing on relevant conceptual and logical issues underlying the overall quest for proving, the volume seeks to cast light on what the effectiveness of proof rests on.
Logos of phenomenology and phenomenology of the logos ; Book Four : The logos of scientific interrogation, participating in nature-Life-saring in life
Prompted and ever diversified by the specifically human interrogative logos, scientific inquiries seek a common system of links in order to mutually confirm and rectify their results. Coming closer and closer to phenomenology, the sciences of life find the common ground of the reality in the ontopoiesis of life.Could it not be that the interrogative logos of science, participating in human creative inventiveness will bring together also the divergent scientific methods in a common network? A network which comprises natural processes, societal sharing-in-life, and existential communication.
Light Scattering Reviews 3 : Light Scattering and Reflection
Ddevoted to modern knowledge and milestones in both experimental and theoretical techniques related to light scattering and radiative transport problems. It will consist of 3 parts comprising 11 contributions written by world leading experts in their respective fields. The general focus of the book will be on remote sensing of geophysical media. The first part will be devoted exclusively to studies of single light scattering by particles of different shapes and chemical compositions. The first chapter will review in situ measurements of cloud optical characteristics like cloud extinction and phase function, with the emphasis on ice clouds. Chapter 2 will cover opitcally soft particles common in marine environments and bio-suspensions while Chapter 3 will describe numerical techniques applicable not only to isotropic but also to chiral and anisotropic mdia. The final chapter in this part will deal with spatial symmetries in light scattering problems.
Asian-Pacific coasts and their management : States of environment
The Asia-Pacific region is home to the world’s largest region of coral reefs and mangroves. It accommodates two-thirds of the world’s human population and its economic activities have the highest growth rate in the world. Ongoing degradation of the environment, resulting from coastal development, deforestation, desertification and over-harvesting, are becoming a matter of great concern, as floods and droughts occur as a result of this degradation. Threats of global environmental change, such as climate change and sea-level rise, will exacerbate such problems. Therefore, appropriate policies and measures are needed for coastal management, to address both the local and global trends. This book gives an overview of the state-of-the-art understanding on the drivers, state, and responses to coastal environmental changes in the Asia-Pacific region. It provides excellent perspectives on current and anticipated environmental changes in the region’s coastal areas, to researchers, students, policy makers, coastal managers and other stakeholders.
