In this volume diatoms of the genus Pinnularia from the Great Xing'an Mountains (in northeastern China), a very pristine region with a great diversity of habitat types, are described. A total of 89 taxa of the genus Pinnularia were studied and documented in both light and scanning electron microscope images. As a result 19 new species are proposed, and 7 neotypes of taxa of Skvortzow are designated. The diatom genus Pinnularia is notoriously difficult taxonomically, with populations having small numbers and apparently great intraspecific phenotypic variability. P.T. Cleve (1895, p. 72) wrote, "The fresh-water forms pass into one another to a great extent, so that the definition of good or distinct species or groups is a matter of greatest difficulty or almost impossible." One of the parts of the world where the freshwater diatom flora is relatively unknown is China. This work will contribute significantly to our understanding of the diversity of the genus Pinnularia overall, and especially in China.

In this volume twenty-three species of Neidium are described. Sample materials were collected in the Zoig� Wetland, an expansive network of lakes and wetlands located in Sichuan Province, China. From the total number of Neidium species reported, sixteen of them are described as new. 281 light microscope and scanning electron microscope photographs document all taxa and illustrate the morphology of these Neidium species. Detailed descriptions for each species are given and the species are compared with other, similar species from other regions of the world. The variability in valve morphology in the genus, including presence and distribution of renilimbi, longitudinal canals, central nodule and striation, are documented. A comprehensive table with morphometric details of all described Neidium species rounds up the volume. This survey of Neidium species almost doubles the number of new Neidium taxa described from China and is of interest for all readers working on diatoms and Bacillariophyceae.

The flora and fauna of Southeast Asia are exceptionally diverse. The region includes several terrestrial biodiversity hotspots and is the principal global hotspot for marine diversity, but it also faces the most intense challenges of the current global biodiversity crisis. Providing reviews, syntheses and results of the latest research into Southeast Asian earth and organismal history, this book investigates the history, present and future of the fauna and flora of this bio- and geodiverse region. Leading authorities in the field explore key topics including palaeogeography, palaeoclimatology, biogeography, population genetics and conservation biology, illustrating research approaches and themes with spatially, taxonomically and methodologically focused case studies. The volume also presents methodological advances in population genetics and historical biogeography. Exploring the fascinating environmental and biotic histories of Southeast Asia, this is an ideal resource for graduate students and researchers as well as environmental NGOs.

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.

Now in its second edition, Pollution of Lakes and Rivers provides essential insights into present-day water quality problems from an international perspective. Explains simply and effectively how lake sediments can be used to reconstruct pollution history Includes over 200 additional references and a new chapter on recent climatic change and its effects on water quality and quantity Tackles present-day water quality problems from an international perspective Previously published by Hodder Arnold PowerPoint slides of the artwork from the book are available from: http://post.queensu.ca/~pearl/textbook.htm Reviews: "This is a very well-written and wide-ranging volume that is both instructive and topical. It is likely to prove useful as an introduction to the general area, a reference source and for teaching purposes." (The Holocene, November 2008) "If you thought that paleolimnology was just mud, pollen, and diatoms then you will likely be both struck by the complexity of this field of research and grateful that John Smol, FRSC, has described it so clearly and broadly. Simply put, the second edition is an excellent book." ( Journal of Phycology, 2008) “This is a useful text. It provides a good level of detail so that the beginner in this area can appreciate what palaeolimnology can (and cannot) achieve. It goes beyond the simple introduction to provide a detailed understanding of how techniques can be applied ... This is a different take on the usual pollution text and would be of great use to those wishing to understand more from sedimentary records.” Taken from the British Ecological Society’s Teaching Ecology website "John Smol has extensive experience in this field of paleoenvironmental research which he combines well with his excellent written communication skills to produce a text that is easy to read but also thought provoking." (Quaternary Science Reviews, 2009) “The breadth of coverage in this text is impressive.” (Lake and Reservoir Management, 2009) “If I could speak with fluidity and clarity in my lectures as consistently as John Smol writes my students would be very grateful.” (Journal of Paleolimnology, 2009)

Due to an awareness of peatlands as a diminishing resource, peatland conservation and rehabilitation has become an important study area. Peatlands and Environmental Change offers a new approach by considering peatlands as a whole ecosystem, and thereby provides a better understanding of the importance and the consequences of the functioning of peatlands. Contents include: * Peat and peatlands * Peat landforms and structure * Peatland hydrology and ecology * Origins and pest initiation * Peat accumulation * The peatland archive: palaeoenvironmental evidence * Autogenic change * Allogenic change * Peatland - environmental feedbacks * Values, exploitation and human impacts * Conservation management and restoration
