Book Description
Diatoms are a major group of algae, and are one of the most common types of phytoplankton. Diatom communities are a popular tool for monitoring environmental conditions, past and present, and are commonly used in studies of water quality. This book presents topical research data in the study of diatoms, including the role of environmental factors in shaping diatom frustule, marine diatom communities, diatom classification methods, an analysis of the diatom flora of lakes, ponds and streams of the Kuril Islands, the ecological information of diatoms provides information on the reconstruction of palaeo-environments, and, the regulatory influences of diatoms on benthic invertebrates.

Book Description
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.

Book Description
Field and laboratory studies were conducted to elucidate the confounding effects of substrate selection, eutrophication, organic pollution, ionic strength, land-use patterns, and heavy metal pollution on benthic diatom communities. Characteristics of benthic diatom communities in relation to pollution level and type were analysed through general criteria and specific criteria. Diatom communities closely reflected the pollution gradient. Diatom-based multivariate water quality assessment results based on different substrates are interchangeable. 17 diatom-based water quality indices developed in other regions proved useful in providing an indication of water quality. Hormesis was demonstrated with a Cd EC50 of 0.077 mg.L-1 being recorded. High metal accumulation capacity by periphyton was demonstrated. Pb and Cr III were shown to decrease the toxicity effects of Cd on periphyton communities. The closer the frequency and duration of the pulse is to a continuous exposure, the greater the effects of the contaminant on aquatic life. Light has a role in modulating the effects of metal toxicants on aquatic life. Diatoms are important indicators of ecological impairment.

Book Description
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? Audience The 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.
