DOWNLOAD EBOOKAquatic 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 EBOOKMethods in Stream Ecology, Second Edition, provides a complete series of field and laboratory protocols in stream ecology that are ideal for teaching or conducting research. This updated edition reflects recent advances in the technology associated with ecological assessment of streams, including remote sensing. In addition, the relationship between stream flow and alluviation has been added, and a new chapter on riparian zones is also included. The book features exercises in each chapter; detailed instructions, illustrations, formulae, and data sheets for in-field research for students; and taxanomic keys to common stream invertebrates and algae. With a student-friendly price, this book is key for all students and researchers in stream and freshwater ecology, freshwater biology, marine ecology, and river ecology. This text is also supportive as a supplementary text for courses in watershed ecology/science, hydrology, fluvial geomorphology, and landscape ecology. Exercises in each chapter Detailed instructions, illustrations, formulae, and data sheets for in-field research for students Taxanomic keys to common stream invertebrates and algae Link from Chapter 22: FISH COMMUNITY COMPOSITION to an interactive program for assessing and modeling fish numbers

DOWNLOAD EBOOKProvides a concise, current and accessible overview of running water systems. The book's unifying focus is on rivers and streams as ecosystems in which the particular identity of organisms is not the main emphasis but rather the processes in which they are involved - specifically energy flow and the cycling of materials.

DOWNLOAD EBOOKFreshwater Mycology: Perspectives of Fungal Dynamics in Freshwater Ecosystems presents chapters from expert contributors around the world. Through the contributed chapters, the contributors explore the perspectives of fungal dynamics in freshwater ecosystems, especially their diversity, distribution, functioning and role, biotransformation and bioprospecting potential, methodical advancements and metagenomic insights. Written with aquatic ecologists in mind, this book provides information on oceanic, estuarine and freshwater ecosystems not currently well understood and identifies new questions and answers about the roles of mycology in aquatic ecosystems. This topic is becoming an increasingly important area to understand due to the increasing global transports of microbes due to climate change and human actions. This is leading to a rapid loss of healthy freshwater ecosystems, the grave problem of antibiotic resistance, and the rarity of qualified mycology taxonomists and molecular systematicians. Includes data from locations not previously or well covered from prior synthesis publications Identifies new information on the roles of mycology in aquatic ecosystems Provides insights into the fungal diversity of freshwater ecosystems, along with their potential roles

DOWNLOAD EBOOKA three-year field study of aquatic hyphomycete communities in a warm-water stream in Illinois was carried out. Two peaks in total frequencies of aquatic hyphomycetes on randomly collected leaves occurred in each year. In contrast, only a single peak in total conidial concentration in water was observed. While total conidial concentrations in water and total frequencies of the species on leaves in each month were moderately correlated, correlation coefficients between species frequencies on leaves and their conidial concentrations in water in each month were not consistent over time. Species composition and relative frequencies in the communities differed at the same time in successive years, suggesting seasonal influences on community structure. In field experiments with multiple sets of leaf baits overlapping in time, communities on leaves of different submergence periods had similar developmental patterns in total frequencies of aquatic hyphomycetes. Low water temperatures delayed development of communities and compressed peaks of total frequencies of occurrence. At higher temperatures, differences in total frequencies among leaves of different submergence periods were greater. In field studies, higher efficiencies of conidial attachment occurred in species with tetraradiate conidia and higher germination percentages occurred in species with sigmoid conidia. The correlation coefficients for each month between efficiencies of conidial attachment and species frequencies on leaves had a bell-shaped curve over the study period (Feb. to Aug. 1995) when the communities on leaves changed from cold to warm season species. In contrast, the correlation coefficients between germination percentages of conidia and species frequencies on leaves changed in an opposite trend. Laboratory studies on other intrinsic characteristics of the fungi indicated that antagonistic abilities did not seem to be important for colonization of aquatic hyphomycetes on leaves. The differentiations between warm and cold season species in sporulation and mycelial growth on leaves at different temperatures were similar to those present during their seasonal abundance in the field. Some of the aquatic hyphomycetes tested in this study appear to have a ruderal life history strategy on submerged leaves. These results from field and laboratory studies contribute to understanding the ecology of aquatic hyphomycetes in streams.
