Branching Morphogenesis
Branching morphogenesis, the creation of branched structures in the body, is a key feature of animal and plant development. This book brings together, for the first time, expert researchers working on a variety of branching systems to present a state-of-the-art view of the mechanisms that control branching morphogenesis. Systems considered range from single cells, to blood vessel and drainage duct systems to entire body plans, and approaches range from observation through experiment to detailed biophysical modelling. The result is an integrated overview of branching.
Boreal Peatland Ecosystems
This volume adopts an ecosystems approach to understanding the world's boreal peatlands. It focuses on biogeochemical patterns and processes, production, decomposition, and peat accumulation, and provides additional information on animal and fungal diversity. A recurring theme is the legacy of boreal peatlands as impressive accumulators of carbon as peat over millennia. This carbon legacy is under threat from a wide diversity of disturbances, including wildfire, ongoing climate change, the changing chemistry of atmospheric deposition, and continuing resource exploitation. The volume is of inte.
Bioterrorism and Infectious Agents : A New Dilemma for the 21st Century
Since the terrorist attack on the United States on September 11, 2001 and subsequent cases of anthrax in Florida and New York City, attention has been focused on the threat of b- logical warfare and bioterrorism. Biological warfare agents are de?ned as “living org- isms, whatever their nature, or infected material derived from them, which are used for h- tile purposes and intended to cause disease or death in man, animals and plants, and depend for their efforts on the ability to multiply in person, animal or plant attacked.” Biological warfare agents may be well suited for bioterrorism to create havoc and terror in a civilian population, because they are cheap and easy to obtain and dispense. Infectious or contagious diseases have played a major part in the history of warfare – deliberately or inadvertently – in restricting or assisting invading armies over the centuries. In 1346, the Tartars catapulted plaque-infected bodies into Kaffa in the Crimea to end a 3-year siege. Blankets contaminated with smallpox to infect North American Indians were used by British forces in the 18th century. More recently, the Japanese released ?eas infected with plaque in Chinese cities in the 1930s and 1940s. Biological research programs for both offensive and defensive strategies have been developed by the United States, Britain, the former Soviet Union, and Canada; several other nations are thought to have such programs.
Biosolids treatment processes ; Vol.6
The past 30 years have seen the emergence of a growing desire worldwide to take positive actions to restore and protect the environment from the degrading effects of all forms of pollution: air, noise, solid waste, and water. The Handbook of Environmental Engineering series guides readers to answer the fundamental questions facing pollution in the modern era – How serious is pollution? Is the technology needed to abate it not only available, but feasible? Among the topics included in this, the sixth edition, are: biosolids, flotation thickening, anaerobic and aerobic digestion, pressurized ozonation, lime stabilization, elutriation and polymer conditioning, and animal waste treatment.
Bioremediation of Soils Contaminated with Aromatic Compounds
Environmental biotechnology, which was in its infancy in the early 80's, has evolved thanks to the revolution brought about by molecular biology. Multiple successes in the biological cleanup of civil and industrial wastewater and of hydrocarbon soil pollution, demonstrate the vast power of clean technologies. In addition, the buildup of information on the activities of microorganisms as catalysts in all sorts of natural, industrial and animal environments has flourished. There is a continuing realization of the critical role of microbial processes in biological, industrial and geological systems. Since environmental biotechnology has matured, it is ready to tackle bigger challenges: the scaling up of many bioremediation systems still in progress, the search for novel biocatalysts for industrial applications, the continuing effort against common human life-threatening processes such as antibiotic resistance, the accumulation of hormone-mimicking substances (endocrine disrupters), the deposition of air-borne pesticides in the environment and, the degradation of recalcitrant contaminants. These endeavors will help prevent the contamination of food chains, protect human life and allow for human activity and economic development that do not compromise environmental sustainabijity.

Biological Low-Voltage Scanning Electron Microscopy
Biological Low-Voltage Scanning Electron Microscopy is the first book to address both of these aspects of biological LVSEM. After providing a thorough description of the unique advantages and the operating constraints related to operating a scanning electron microscope at low beam voltage, the remainder of book focuses on the the best way to image all types of plant and animal cells and covers specimens that range from macromolecules to the surfaces revealed by de-embedding resin-embedded samples. Advanced specimen preparation techniques such as cryo-LVSEM, and immuno-gold-LVSEM are fully covered, as is x-ray microanalysis at low beam voltage and live-time stereo imaging. The preparative protocols provided represent the distilled essence of the experience of a group of world-renowned authors who have, for many decades, been instrumental in developing and applying new approaches to LVSEM to support their own biological research.
Biological Invasions in South Africa
This book presents a comprehensive account of all aspects of biological invasions in South Africa, where research has been conducted over more than three decades, and where bold initiatives have been implemented in attempts to control invasions and to reduce their ecological, economic and social effects.
Biological Invasions
This new volume on Biological Invasions deals with both plants and animals. It differs from previous books on the subject by extending from the level of individual species to an ecosystem and global level. Topics of highest societal relevance, such as the impact of genetically modified organisms, are interlinked with more conventional ecological aspects, including biodiversity. The combination of these approaches is new and makes compelling reading for researchers and environmentalists. The book’s 22 chapters cover a huge range of subjects relevant to the field. These include pathways of biological invasions (e.g. ballast water, waterways), traits of successful invaders (e.g. chemical weapons, empty niches), and patterns of invasion and invasibility, such as man-induced predisposition by fire, land use and eutrophication, and the role of climate change.
Biological adhesives
Many plants, animals, and microbes use adhesive polymers and structures to attach to inert substrates, to each other, or to other organisms. This is the first major review that brings together research on many of the well-known biological adhesives. Emphasizing the diversity of biological adhesives and associated adhesion processes, it deals with bacteria, fungi, algae, and marine and terrestrial animals. It bridges a variety of disciplines including biochemistry, molecular biology, biomechanics, bioengineering, microbiology, organism structure and function, and ultrastructure. As we learn more about the molecular and mechanical properties of these adhesives, we begin to understand why they adhere so well and how they develop cohesive strength. With this understanding comes the prospect of developing synthetic or semi-synthetic adhesives with broad applications in areas such as medicine, dentistry, and biotechnology. The book is suitable for both industrial and academic researchers.

Biodiversity Conservation and Phylogenetic Systematics : Preserving our evolutionary heritage in an extinction crisis
This book brings an updated state of the art of phylogenetic diversity in conservation biology. Nineteen chapters written by scientists from research institutions of fourteen countries demonstrate that approaches for preserving the evolutionary heritage are now very tuned into human impacts and sustainability issues. The questions, methods and applications around which it is organized show the importance of phylogenetic diversity in avoiding biodiversity losses in the present extinction crisis. They touch important points such as the way we value phylogenetic diversity, the importance of thinking at a much wider sample of the Tree of Life, the choice of adequate measures. In methods section, new solutions, such as dealing with abundances, sampling effort, or with information coming from conflicting phylogenetic trees are provided. Application section includes study cases of different groups of organi
Bioactive components of milk
Of all food products dairy foods have the most potential concerning functional foods. Therefore, there is a tremendous amount of interest in value-added milk products and the identification of components in food which have health benefits. Bioactive Components of Milk provides an overview of these derived components and their diverse activities including: the stimulation of beneficial microflora, alerting the immune system to the presence of potential pathogens and allergens, binding and eliminating toxins, etc. The book is divided into four parts. The first part focuses on bioactive milk lipid components, which very widely among mammalian species. The second part describes different aspects of biological active colostrums and milk proteins and their derivatives, with special concern on species specific effects. The third part reviews the production of recombinant human proteins in the milk of livestock animals - including ethical issues - and the aims of altering milk composition for the benefit of both the animals themselves and the consumers. The final part focuses on the influence of ruminants nutrition on the biological activity of milk.
Bearing Witness : Ruth Harrison and British Farm Animal Welfare (1920–2000)
This book is the biography of one of Britain’s foremost animal welfare campaigners and of the world of activism, science, and politics she inhabited. In 1964, Ruth Harrison’s bestseller Animal Machines triggered a gear change in modern animal protection by popularising the term ‘factory farming’ alongside a new way of thinking about animal welfare.
Bacteriocins : Ecology and Evolution
Microbes produce an extraordinary array of defense systems. These include bacteriocins, a class of antimicrobial molecules with narrow killing spectra, produced by bacteria. The book describes the diversity and ecological role of bacteriocins of Gram-positive and Gram-negative bacteria, presenting a new classification scheme for the former and a state-of-the-art look at the role of bacteriocins in bacterial communication. It discusses the molecular evolution of colicins and colicin-like bacteriocins, and provides a contemporary overview of archaeocins, bacteriocin-like antimicrobials produced by archaebacteria. Furthermore, various modeling (in silico) studies elucidate the role of bacteriocins in microbial community dynamics and fitness, delving into rock-paper-scissors competition and the counter-intuitive survival of the weakest. The book makes compelling reading for a multi-faceted scientific audience, including those working in the fields of biodiversity and biotechnology, notably in the human and animal health domain.

This book will focus on psychophysics and perception as well as being relevant to basic auditory research.
Asymmetric Cell Division
Cell biologists have recently become aware that the asymmetry of cell division is an important regulatory phenomenon in the fate of a cell. During development, cell diversity originates through asymmetry; in the adult organism asymmetric divisions regulate the stem cell reservoir and are a source of the drift that contributes to the aging of organisms with renewable cell compartments. Because of the concept of semi-conservative DNA synthesis, it was thought that the distribution of DNA between daughter cells was symmetric. The analysis of the phenomenon in cells during mitosis, however, revealed the asymmetry in the distribution of the genetic material that creates the drift contributing to aging of mammals. On the other hand, cancer cells can originate from a deregulation of asymmetry during mitosis in particular during stem cell expansion. The book describes the phenomenon in different organisms from plants to animals and addresses its implications for the development of the organism, cell differentiation, human aging and the biology of cancers.
Astrophysics : A new approach
For a quantitative understanding of the physics of the universe - from the solar system through the milky way to clusters of galaxies all the way to cosmology - these edited lecture notes are perhaps among the most concise and also among the most critical ones: Astrophysics has not yet stood the redundancy test of laboratory physics, hence should be wary of early interpretations. Special chapters are devoted to magnetic and radiation processes, supernovae, disks, black-hole candidacy, bipolar flows, cosmic rays, gamma-ray bursts, image distortions, and special sources. At the same time, planet earth is viewed as the arena for life, with plants and animals having evolved to homo sapiens during cosmic time. -- This text is unique in covering the basic qualitative and quantitative tools, formulae as well as numbers, needed for the precise interpretation of frontline phenomena in astrophysical research. The author compares mainstream interpretations with new and even controversial ones he wishes to emphasize.
