Diatoms: Biology and Applications - Böcker

DIATOM MORPHOGENESIS A unique book presenting the range of silica structures formed by diatoms, theories and hypotheses of how they are made, and applications to nanotechnology by use or imitation of diatom morphogenesis. 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: A tutorial chapter, with a glossary for newcomers to the field, who are often from outside of biology, let alone phycology;Diatom Morphogenesis: general issues, including symmetry and size issues;Diatom Morphogenesis: simulation, including analytical and numerical methods for description of the diatom valve shape and pore structure;Diatom Morphogenesis: physiology, biochemistry, and applications, including the relationship between taxonomy and physiology, biosilicification hypotheses, and ideas about applications of diatoms.Audience Researchers, scientists, and graduate students in the fields of phycology, general biology, marine sciences, the chemistry of silica, materials science, and ecology.

DIATOM MICROSCOPY The main goal of the book is to demonstrate the wide variety of microscopy methods being used to investigate natural and altered diatom structures. This book on Diatom Microscopy gives an introduction to the wide panoply of microscopy methods being used to investigate diatom structure and biology, marking considerable advances in recent technology including optical, fluorescence, confocal and electron microscopy, surface-enhanced Raman spectroscopy (SERS), atomic force microscopy (AFM) and spectroscopy as applied to diatoms. Each chapter includes a tutorial on a microscopy technique and reviews its applications in diatom nanotechnology and diatom research. The number of diatomists, diatom research, and their publications are increasing rapidly. Although many books have dealt with various aspects of diatom biotechnology, nanotechnology, and morphology, to our knowledge, no volume exists that summarizes advanced microscopic approaches to diatoms. Audience The intended audience is academic and industry researchers as well as graduate students working on diatoms and diatom nanotechnology, including biosensors, biomedical engineering, solar panels, batteries, drug delivery, insect control, and biofuels.

This comprehensive guide is designed for researchers, professionals, and students looking to deepen their knowledge of diatoms, including detailed information on diatom photosynthesis regulation at the molecular scale, as well as their significant ecological roles, all aimed at promoting sustainable advancements and the safeguarding of aquatic ecosystems. Diatoms exert an immense influence on the ecosystem of Earth due to their remarkable abundance and species diversity. Thriving in diverse habitats spanning the oceans, intertidal benthic zones, saline and freshwater environments, and even terrestrial niches like moist soil, forests, and caves, they play an integral role. Diatoms alone account for around 20% of the oxygen generated by photosynthesis, comparable to the combined productivity of tropical rainforests worldwide, while their primary production can reach 40–45% in marine ecosystems. Nevertheless, in contrast to the extensive research on macroscopic photosynthetic organisms, investigations in this domain remain comparatively limited, despite the role of diatoms in global biogeochemical processes. This book presents an exhaustive review of the subject matter, encompassing a wide spectrum of topics ranging from the intricate molecular mechanisms of diatom photosynthesis and light absorption to the dominant role of diatoms as primary producers within ecological frameworks. Beyond this, the book delves into the practical implications stemming from diatoms and their photosynthetic productivity. A strong emphasis is placed on the importance of fundamental research in deepening our understanding of the natural world around us.

This book offers a comprehensive, unique and up-to-date exploration of diatom ecology spanning from fundamental molecular aspects to the intricate dynamics of metacommunities. In recent years there has been a considerable increase in the amount of research devoted to diatom ecology, with a wide spectrum of approaches. This large amount of information, published in many different journals and books, makes it very difficult to keep up to date, both for the trained researcher and for students. Eduardo A. Morales (d. May 2023) had the original idea to assemble chapters on various subjects within diatom ecology. The questions he posed to potential contributors framed the current book consisting of 12 chapters. Are diatoms suitable tools for ecological restoration? What would be the features that make them reliable in this context?What makes diatoms ecologically successful?In an ecological sense, why is there such variability in diatom reproductive strategies and why are they worth considering?What do new approaches in ecological synthesis provide to diatom ecology, biogeography and metacommunities?Are all diatoms widely spread and each species uniquely characterized by its own, unaltered phenotype?Can we really make any ecological consideration without knowing (with a high degree of certainty) the identity of taxa?Are urban ecosystems important repositories of biodiversity?What are the benefits and the progress in diatom ecology made by the diatom guild perspective? Why, how and when are soil diatoms used in bioindication and what are the benefits of such an approach?Are diatoms bona fide indicators of climate change?Are diatom communities in temporary rivers important for these lotic ecosystems as they are subjected to the effects of climate change? Do diatoms in peatlands behave differently from their terrestrial and aquatic (rivers, lakes, others) counterparts?AudienceThe book is intended primarily for professionals in the fields of diatom research, algal research (phycology), organismal, population and community ecology, limnology, microbiology, organismal biology, paleoecology and paleolimnology. The book will also serve as a reference for graduate students seeking guidance on terminology, techniques, and current methods in diatom research.
