Download or read book The Ecology of Aquatic Hyphomycetes written by Felix Bärlocher and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic hyphomycetes were discovered 50 years ago by C.T. Ingold. They remained a relatively obscure group until their role as intermediaries between deciduous leaves and stream invertebrates was established some 20 years ago. This book, for the first time, provides a comprehensive summary and critical evaluation of the biology and ecology of these organisms. Aspecial effort was made to evaluate the potential and actual insight that have been or will be derived from work in related disciplines such as the ecology of other fungal groups, stream ecology, or population ecology. The topics treated include the basic life history of the fungi and the potential role of wood, a discussion of how the fungi have adjusted to life in running water, their interactions with invertebrates, the attachment and germination of their spores, what is known about sexual reproduction, how water chemistry may influence their distribution and activity, how they react to human degradation of their environment, and a summary of the research done on the Indian subcontinent. The volume is of special interest to mycologists and stream ecologists and should facilitate the entry of new workers into this exciting area.

Download or read book The Llobregat written by Sergi Sabater and published by Springer. This book was released on 2012-06-02 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Llobregat belongs to the most thoroughly studied rivers in Europe and is a paradigm of the confluence of human and natural disturbances in a single basin. Because of its location in a very densely populated region and its Mediterranean character, the Llobregat supports a mixture of irregular flow, water abstraction, excess nutrients, mining debris, and a wide array of pollutants. The aquatic organisms strive to survive in a dramatically changing river that passes through a succession of dams, weirs and channels. The long-term river monitoring as well as the research that has been carried out in the river for a long time have provided an extensive knowledge of these disturbances and their effects on the biological communities. This book highlights the available information, with emphasis on the hydrological, chemical and biological elements interspersed in the river. Experts in the field discuss the main nutrient patterns and pollutant occurrence and the responses of the biological quality elements as well as the river ecosystem to the overall natural and man-made influences.

Download or read book Evolution by Means of Hybridization written by J.P. Lotsy and published by Springer. This book was released on 1916 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: As aPreface is in reality a Postscriptum, the author may be permitted to open it by mentioning omissions. The chief sin of omission he committed, is evidently the insuffident justice he did to the writings of Anton Kerner von Marilaun, who was - he wants to state this explicitly - the first to recognize fully the significance of crossing as the underlying cause of the origin of spedes. What else should apreface say? If the work is as condensed as the present one, it may perhaps suffise to repeat what Linnaeus said to Haller: Si quos in me vidisti errores, Tu sapientior haec ignoscas. . .. Quos plures apud me detegere potes, eo gratior ero, tum possum omnia corrigere vivus; post mortem non licet emendare propria opuscula. By which however the author does not consider himself bound to gratefulness for every kind of critidsm. He is f. i. very little impressed by the kind of criticism which calls it "inconceivable" "verging on the absurd" etc., to believe that crossing can ever have been the underlying cause of the origin of new spedes, from authors who firmly believe that the origin of new spedes should be ascribed to some kind of variability; because it seems to him "absurd" that those who advocate the origin of new spedes from a single ances­ tral one, should reproach an author who defends such an origin from two ancestral species, of stating an "inconceivable" opinion.

Book excerpt: The Yeasts: A Taxonomic Study is a three-volume book that covers the taxonomic aspect of yeasts. The main goal of this book is to provide important information about the identification of yeasts. It also discusses the growth tests that can be used to identify different species of yeasts, and it examines how the more important species of yeasts provide information for the selection of species needed for biotechnology. • Volume 1 discusses the identification, classification and importance of yeasts in the field of biotechnology. • Volume 2 focuses on the identification and classification of ascomycetous yeasts. • Volume 3 deals with the identification and classification of basidiomycetous yeasts, along with the genus Prototheca. - High-quality photomicrographs and line drawings - Detailed phylogenetic trees - Up-to-date, clearly presented yeast taxonomy and systematic, easy-to-use reference sequence accession numbers to allow for correct identification
