Available in PDF, EPUB and Kindle. Book excerpt: Freshwater Algae of North America: Ecology and Classification, Second Edition is an authoritative and practical treatise on the classification, biodiversity, and ecology of all known genera of freshwater algae from North America. The book provides essential taxonomic and ecological information about one of the most diverse and ubiquitous groups of organisms on earth. This single volume brings together experts on all the groups of algae that occur in fresh waters (also soils, snow, and extreme inland environments). In the decade since the first edition, there has been an explosion of new information on the classification, ecology, and biogeography of many groups of algae, with the use of molecular techniques and renewed interest in biological diversity. Accordingly, this new edition covers updated classification information of most algal groups and the reassignment of many genera and species, as well as new research on harmful algal blooms. - Extensive and complete - Describes every genus of freshwater algae known from North America, with an analytical dichotomous key, descriptions of diagnostic features, and at least one image of every genus. - Full-color images throughout provide superb visual examples of freshwater algae - Updated Environmental Issues and Classifications, including new information on harmful algal blooms (HAB) - Fully revised introductory chapters, including new topics on biodiversity, and taste and odor problems - Updated to reflect the rapid advances in algal classification and taxonomy due to the widespread use of DNA technologies

Download or read book Green Plants written by Peter R. Bell and published by Cambridge University Press. This book was released on 2000-09-28 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: The central theme of Green Plants, first published in 2000, is the astonishing diversity of forms found in the plant kingdom, from the simplicity of prokaryotic algae to the myriad complexities of flowering plants. The book is arranged according to generally accepted classification schemes, beginning with algae (prokaryotic and eukaryotic) and moving through mosses, liverworts, fern allies, ferns and gymnosperms to flowering plants. Copiously illustrated throughout, it provides a concise account of all algae and land plants, with information on topics from cellular structure to life cycles and reproduction. The authors maintain a refreshingly cautious approach in discussions of possible phylogenetic relationships and include newly emerging information on features of plants known only as fossils. This edition has been completely updated to reflect current views on the origin of the major groups of plants, providing a resource for students of botany, and for researchers needing a comprehensive reference to the plant kingdom.

Download or read book The Atna River written by Odd Terje Sandlund and published by Springer Science & Business Media. This book was released on 2004-04-30 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a unique set of time series data concerning the environmental and biological dynamics of a pristine alpine-boreal river system in Norway. A simultaneous collection of data on climate, hydrology, erosion, water chemistry, primary production, invertebrates and fish provides an unusual insight into the ecology of a watercourse characteristic of this region of north-western Europe. Individual papers present data collected over 14 years, which provides an opportunity to understand the natural dynamics in a system with very little direct influence from human activities. The results indicate a level of variation that should be expected in natural systems, and provides a solid basis for a discussion of the best approach to the monitoring of biological diversity and environmental factors in rivers and lakes. The volume is aimed at researchers working with watershed management and aquatic sciences. It provides useful information and experiences of particular relevance to the implementation of the EU Frame Directive for Water.

Download or read book Desmids of the Lowlands written by Peter F.M. Coesel and published by BRILL. This book was released on 2014-04-14 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algal species and in particular desmids are important indicators of water quality. Because of their preferential occurrence in vulnerable habitats, desmids lend themselves well to figuring in conservation studies. The present flora describes all desmid taxa known from the Netherlands and adjacent lowland areas: over 500 species and more than 150 additional varieties. Because of the predominantly cosmopolitan nature of most species the flora may also be of use outside this geographic region. The enclosed CD-ROM offers general information on desmid biology as well as a selection of species that are discussed in more detail. Ecological data, both on separate species and desmid communities, enable a characterization of the habitat sampled. Volume 1: Desmids of the Lowlands - Mesotaeniaceae and Desmidiaceae of the European Lowlands Volume 2: European Flora of the desmid genera Staurastrum and Staurodesmus

Download or read book Algae written by Christiaan Hoek and published by Cambridge University Press. This book was released on 1995 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algae are ubiquitous. A multitude of species, ranging from microscopic unicells to gigantic kelps, inhabit the world's oceans, freshwater bodies, soils, rocks and trees. To understand the basic role of algae in the global ecosystem, a reliable and modern introduction to their kaleidoscopic diversity, systematics and phylogeny is indispensible. This volume provides such an introduction. The text represents a completely revised and updated edition of a highly acclaimed German textbook which was heralded for its clarity as well as its breadth and depth of information. This new edition takes into account recent re-evaluations in algal systematics and phylogeny which have been made necessary by insights provided by the powerful techniques of molecular genetics and electron microscopy, as well as more traditional life history studies.

Download or read book The Collections Museums and Gardens of G ttingen University written by Ulrike Beisiegel and published by Göttingen University Press. This book was released on 2015 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The University of Göttingen possesses within its research and teaching collections, exhibitions and diverse range of gardens, unique museum holdings in an exceptionally wide range of knowledge domains. Among these are many objects and convolutes of outstanding significance worldwide. These notable holdings have always played an important role in student life and the academic work pursued at Göttingen University, as well as in university members’ training and research activities. The beginnings of the collections date back to a time well before the founding of the university itself in 1737. Initially existing in isolation as the Naturalien Cammer (Cabinet of Natural Curiosities), botanical collection, numismatic collection or model collection, in 1773 several of them were brought together in terms of space and content as the Königliches Academisches Museum (Royal Academic Museum) and extended considerably. Some of the collections continued to exist into the early 20th century as the Naturhistorisches Museum (Natural History Museum), but ultimately, in the late 1920s and early ’30s at the latest, they were transferred to separate institutes and have since been maintained separately. Many of the collections play an important role in the university’s research and teaching, as for a large number of subject areas material objects are indispensable for didactical, investigative and learning processes. The relevance of other collections, however, lies above all in their contribution to the history of science and knowledge, vividly bringing to life and illustrating archive and book holdings also held by the university. This rich heritage gives the University of Göttingen special opportunities, but it also brings obligations. The collections and gardens should be accessible for use in the research context, preserved for future generations, and also remain available for university teaching. This necessarily involves the responsible supervision and care of holdings by curators or, in the case of smaller collections, by members of the university taking on responsibility for them in a part-time capacity. In presenting this Collections Guide, the University of Göttingen would like to inform its staff, students and the general public from near and far about its rich and diverse museums holdings from the areas of art, cultural history, archaeology, ethnography and ethnology, cultural anthropology, medicine, the natural sciences and mathematics, and warmly invites guests to visit them.
