Available in PDF, EPUB and Kindle. Book excerpt: A 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.
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 Ecology of Plant Litter Decomposition in Stream Ecosystems written by Christopher M. Swan and published by Springer Nature. This book was released on 2021-08-01 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: With almost 90% of terrestrial plant material entering the detrital pool, the processing of this significant carbon source is a critical ecosystem function to understand. Riverine ecosystems are estimated to receive, process and transport nearly 1.9 Pg of terrestrial carbon per year globally, highlighting the focus many freshwater ecologists have on the factors that explain decomposition rates of senesced plant material. Since Webster and Benfield offered the first comprehensive review of these factors in 1986, there has been an explosion of research addressing key questions about the ecological interactions at play. Ecologists have developed field and laboratory techniques, as well as created global scale collaborations to disentangle the many drivers involved in the decomposition process. This book encapsulates these 30+ years of research, describing the state of knowledge on the ecology of plant litter decomposition in stream ecosystems in 22 chapters written by internationally renowned experts on the subject.

Download or read book Perspectives in Running Water Ecology written by M. Lock and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discipline of stream ecology has grown exponentially along with most other areas of science in the last three decades. The field has changed from a fish management-dominated poor-sister of limnology to a discipline with theoretical constructs and ecological insights as rich as those in any area of ecology. A focus on energy transformations, nutrient turnover and the storage and processing of organic substrates has greatly enhanced the development of current paradigms. For example, the data base on microbial-biochemical invertebrate interactions in streams is now very extensive. A survey of the stream ecology literature reveals the central role played by H.B. Noel Hynes, whom I believe to be the world's premier lotic ecologist. Professor Hynes produced the major text in the field ("The Ecology of Running Waters") which has served both as an integrative review and as a bridge between the fish-water quality orientation of the fifties and sixties to the process oriented, nutritional resource-watershed perspectives of the seventies. It should also be noted that Professor Hynes' book, "The Biology of Polluted Waters", served as a basic reference for the earlier period and he has published over 150 research papers, the great majority in stream ecology, spanning four decades.
