Book Description
The authors present a taxonomic study of benthic diatoms collected from coastal rocks in seven northern Mediterranean sites (Italy, Spain, Greece, Turkey) in spring of 2010. An iconographic catalogue of high-quality SEM and light microscopic images, plus detailed taxonomic, nomenclatural and bibliographic information, are provided as a practical reference for further taxonomic and floristic studies on 91 plates. 120 representative diatom taxa, among them several poorly known species, selected from 23 samples, are described in terms of their abundance. The authors provide detailed information on the type material of each diatom species, a list of synonyms, a comparison of morphometric data provided in the literature (in tables) and a series of iconographic SEM-images which illustrate the taxon’s morphological variability, plus an exhaustive list of references. Nomenclature, taxonomy and systematic position of the described taxa are updated. Eight taxa are described as new to science and another seven are nomenclaturally recombined. Eight taxa are new records for the Mediterranean Sea and for five taxa Scanning Electron Microscope (SEM) images are presented for the first time. An exhaustive reference list and indices of taxa conclude this volume and make it a valuable source of information for biologists working on benthic diatoms in general, not only of the Mediterranean region.

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
Conservation and biodiversity of protists The conservation of biodiversity is not just an issue of plants and vertebrates. It is the scarcely visible invertebrates and myriads of other microscopic organisms that are crucial to the maintenance of ecological processes on which all larger organisms and the composition of the atmosphere ultimately depend. Biodiversity and Conservation endeavours to take an holistic view of biodiversity, and when the opportunity arises to issue collections of papers dealing with too-often neglected groups of organisms. The protists, essentially eukaryotes that cannot be classi?ed in the kingdoms of animals, fungi, or plants, include some of the lea- known groups of organisms on earth. They are generally treated as a separate kingdom, commonly named Protista (or Protoctista) in textbooks, but in reality they are a mixture of organisms with disparate a?nities. Some authors have hypothesized that the numbers of protists are not especially large, and that many have extraordinarily wide distributions. However, the p- ture that unfolds from the latest studies discussed in this issue is di?erent. There are many species with wide ranges, and proportionately more cosmopolitan species than in macroorganism groups, as a result of their long evolutionary histories, but there are also de?nite patterns and geographical restrictions to be found. Further, some protists are linked to host organisms as mutualists or parasites and necessarily con?ned to the distributions of their hosts.

Book Description
Diatom biology, genomics and ecology are becoming more relevant to the human species. While there have been recent compilations of some of the applied aspects of diatoms, and the dizzying pace of taxonomic revisions, this new volume bring us up to date on their classification, biology and ecology, as well as covering the topics of genomics and applied uses. In this collection, some of the leaders in diatom research present either new information or summarize recent research efforts on a wide range of topics, including the tree of life of diatoms, their classifications, the wide habitats and ecological spectra the group exploits, as well as the beauty of their form. This volume celebrates the diversity, emerging areas of research and fascinating ecology of the diatoms bringing this group of world-renown and emerging research leaders together. 'The Diatom World' will foster greater appreciation and research contributions on this incredibly diverse and fascinating group of organisms.

Book Description
This book is an introduction to diatom biology. It emphasizes the cell cycle, sexual reproduction, and ontogeny. The authors have provided a system of classification with many new taxa described at the family level together with 17 new genera.

Book Description
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.
