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.

MATHEMATICAL MACROEVOLUTION IN DIATOM RESEARCH Buy this book to learn how to use mathematics in macroevolution research and apply mathematics to study complex biological problems. This book contains recent research in mathematical and analytical studies on diatoms. These studies reflect the complex and intricate nature of the problems being analyzed and the need to use mathematics as an aid in finding solutions. Diatoms are important components of marine food webs, the silica and carbon cycles, primary productivity, and carbon sequestration. Their uniqueness as glass-encased unicells and their presence throughout geologic history exemplifies the need to better understand such organisms. Explicating the role of diatoms in the biological world is no more urgent than their role as environmental and climate indicators, and as such, is aided by the mathematical studies in this book. The volume contains twelve original research papers as chapters. Macroevolutionary science topics covered are morphological analysis, morphospace analysis, adaptation, food web dynamics, origination-extinction and diversity, biogeography, life cycle dynamics, complexity, symmetry, and evolvability. Mathematics used in the chapters include stochastic and delay differential and partial differential equations, differential geometry, probability theory, ergodic theory, group theory, knot theory, statistical distributions, chaos theory, and combinatorics. Applied sciences used in the chapters include networks, machine learning, robotics, computer vision, image processing, pattern recognition, and dynamical systems. The volume covers a diverse range of mathematical treatments of topics in diatom research. Audience Diatom researchers, mathematical biologists, evolutionary and macroevolutionary biologists, paleontologists, paleobiologists, theoretical biologists, as well as researchers in applied mathematics, algorithm sciences, complex systems science, computational sciences, informatics, computer vision and image processing sciences, nanoscience, the biofuels industry, and applied engineering.

This book is the first in the series of volumes that will be devoted to the Eurasian Sphagnum bog diatoms. Sphagnum bogs are unique ecosystems. The main ecological drivers in these systems are Sphagnum mosses. They originate under organic, acidic conditions with low content of available electrolytes. Diatomological studies of the Sphagnum bogs of Russia and adjacent countries began in the 1950s. However, these papers include the floristic information on only a few dozen smaller bogs. Large-scale floristic, taxonomic and biogeographic investigations have not been conducted so far, although this gap has been reduced by a few recent studies. Diatom assemblages from Sphagnum bog Nur, situated in the northern mountainous region of Mongolia, are subject of the study. Nur is a unique ecosystem in Mongolia because it is the only known large Sphagnum bog throughout this region. There are no earlier studies on the algal flora of this ecosystem. A total of 242 diatom taxa, belonging to 48 genera have been identified from samples taken from different habitats of this bog. Light and scanning electron microscope analyses resulted in the description of one new genus, Boreozonacola, and 18 new species from the genera Pinnularia, Stauroneis, Naviculadicta, Fragilaria, Eunotia, Boreozonacola, Caloneis, Chamaepinnularia, and Neidium. Additionally, 11 new taxonomic combinations are suggested. Species treatments include descriptions, synonymies, size dimensions, and relevant literature. For some species historical information is also provided.

This reference book covers the ecological impact and biotechnological applications of diatoms. Diatoms contribute to 40% of primary productivity in aquatic ecosystems. They have a unique biomonitoring ability and sensitivity toward different pollutants in wastewater, and are thereby a tool for ecotoxicological monitoring. The book discusses the need for newer diatom-based indices for wastewater quality analysis. It describes the nutraceutical value of the myriad compounds like omega 3 fatty acids-DHA, polysaccharides, and phenols in diatoms. It also elaborates on the challenges in sustainable diatom biorefinery. This book is meant for microbiologists, biotechnologists, and marine biologists.
