There are up to 200,000 species of diatoms, each species of these algal cells bearing an ornate,amorphous silica glass shell. The silica is structured at 7 orders of magnitude size range, and is thus the most complex multiscalar solid structure known. Recent research is beginning to unravel how a single cell marshals chemical, physical, biochemical, genetic, and cytoskeletal processes to produce these single cell marvels. The field of diatom nanotechnology is advancing as this understanding matures. Diatoms have been actively studied over the recent 10-20 years with various modern equipment, experimental and computer simulation approaches, including molecular biology, fluorescence-based methods, electron, confocal and AFM microscopy. This has resulted in a huge amount of information but the key stages of their silica morphogenesis are still not clear. This is the time to reconsider and consolidate the work performed so far and to understand how we can go ahead. The main objective of this book is to describe the actual situation in the science of diatom morphogenesis, to specify the most important unresolved questions and to present the corresponding hypotheses. The following areas are discussed: 1. A tutorial chapter, with a glossary for newcomers to the field, who are often from outside of biology, let alone phycology. 2. Diatom Morphogenesis: general issues, including symmetry and size issues. 3. Diatom Morphogenesis: simulation, including analytical and numerical methods for description of the diatom valve shape and pore structure. 4. Diatom morphogenesis: physiology, biochemistry, and applications, including the relationship between taxonomy and physiology, biosilicification hypotheses, and ideas about applications of diatoms.

The aim of this new book series (Diatoms: Biology and Applications) is to provide a comprehensive and reliable source of information on diatom biology and applications. The first book of the series, Diatoms Fundamentals & Applications, is wide ranging, starting with the contributions of amateurs and the beauty of diatoms, to details of how their shells are made, how they bend light to their advantage and ours, and major aspects of their biochemistry (photosynthesis and iron metabolism). The book then delves into the ecology of diatoms living in a wide range of habitats, and look at those few that can kill or harm us. The book concludes with a wide range of applications of diatoms, in forensics, manufacturing, medicine, biofuel and agriculture. The contributors are leading international experts on diatoms. This book is for a wide audience researchers, academics, students, and teachers of biology and related disciplines, written to both act as an introduction to diatoms and to present some of the most advanced research on them.

The book will cover a broad range of work describing our current state of understanding on the topic, including: historic knowledge and misconceptions of motility; evolution of diatom motility; diatom ecology & physiology; cell biology and biochemistry of diatom motility, anatomy of motile diatoms; observations of diatom motile behavior; diatom competitive ability, unique forms of diatom motility as found in the genus Eunotia; and Models of Motility. This volume is the first book attempting to gather such information surrounding diatom motility into one volume focusing on this single topic. Readers will be able to gather both the current state of understanding on the potential mechanisms and ecological regulators of motility, as well as possible models and approaches used to help determine how diatoms accomplish such varied behaviors as diurnal movements, accumulation into areas of light, niche partitioning to increase species success. Given the fact that diatoms remain one of the most ecologically crucial cells in aquatic ecosystems, our hope is that this volume will act as a springboard towards future research into diatom motility and even better resolution of some of the issues in motility.

This much revised and expanded edition provides a valuable and detailed summary of the many uses of diatoms in a wide range of applications in the environmental and earth sciences. Particular emphasis is placed on the use of diatoms in analysing ecological problems related to climate change, acidification, eutrophication, and other pollution issues. The chapters are divided into sections for easy reference, with separate sections covering indicators in different aquatic environments. A final section explores diatom use in other fields of study such as forensics, oil and gas exploration, nanotechnology, and archaeology. Sixteen new chapters have been added since the first edition, including introductory chapters on diatom biology and the numerical approaches used by diatomists. The extensive glossary has also been expanded and now includes over 1,000 detailed entries, which will help non-specialists to use the book effectively.

Developing organisms are systems in which the geometry, dynamics, and boundary conditions are all changing in the course of morphogenesis. The morphogenesis of cells and organisms appear to be mediated in part by the mechanically active components of the cytoskeleton. Mechanical forces have long been considered secondary to the effects of molecular mechanisms in cell growth, differentiation, and development. This volume explores the role of mechanical forces in cell growth and development and demonstrates its importance. This volume will prove invaluable to all biologists interested in the fundamentals of mechanical forces in development, from the advanced to the graduate researcher.

Secretions and emissions in biological systems play important signaling roles within the organism but also in its communications with the surrounding environment. This volume brings together state-of-the-art information on the role of secretions and emissions in different organs and organisms ranging from flowers and roots of plants to nematodes and human organs. The plant chapters relate information regarding the biochemistry of flower volatiles and root exudates, and their role in attracting pollinators and soil microbial communities respectively. Microbial chapters explain the biochemistry and ecology of quorum sensing and how microbial communities highly co-adapted to plants can aid in bio-energy applications by degrading ligno-cellulosic materials. Other chapters explain the biology of secretions by nematodes, algae and humans, among other organisms. This volume will be a welcome addition to the literature, as no other book covers aspects related to biological secretion in such a holistic and integrative manner.

Protists represent an immensely diverse group of organisms comprised of algae, fungi and protozoa. The nature of protistan cell surface is as diverse as the terminology that has evolved to describe the various surface components. This terminology is defined and discussed in the opening of this book. The remaining contributions provide an up-to-date synopsis of structure, development and function of protistan cell surfaces, including their role in taxonomy and systematics.

This book contains full papers of both oral and poster presentations of the international symposium 'Marine Bioprocess Engineering' which was held in Noordwijkerhout, The Netherlands, 1998. The symposium focused on the bioprocessing of marine natural products. Bioprocess engineering has been the key to success in the commercialization of biotechnology, especially with respect to biopharmaceuticals. In marine biotechnology, both new and existing biotechnological techniques are developed an applied to organisms from marine sources. For marine biotechnology, bioprocess engineering represents the link between discovery and commercialization. The diversity of marine life points to a myriad of new bioproducts waiting to be discovered and developed commercially. The volume begins to bridge the gap between the isolation of products from marine organisms in the laboratory and industrial applications by focusing on the bioprocess-engineering aspects. Reviews and recent developments in product discovery, bio-energy production, cultivation of marine organisms, scale up and product recovery are presented. This publication should ensure that the engineering aspects of marine biotechnology will receive further attention in the future. Exploration of new bioproducts from the ocean should be followed up by a sustainable exploitation of these valuable resources.
