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.

Available in PDF, EPUB and Kindle. Book excerpt: As the vast expanses of natural forests and the great populations of salmonids are harvested to support a rapidly expanding human population, the need to understand streams as ecological systems and to manage them effectively becomes increasingly urgent. The unfortunate legacy of such natural resource exploitation is well documented. For several decades the Pacific coastal ecoregion of North America has served as a natural laboratory for scientific and managerial advancements in stream ecology, and much has been learned about how to better integrate ecological processes and characteristics with a human-dominated environment. These in sightful but hard-learned ecological and social lessons are the subject of this book. Integrating land and rivers as interactive components of ecosystems and watersheds has provided the ecological sciences with impor tant theoretical foundations. Even though scientific disciplines have begun to integrate land-based processes with streams and rivers, the institutions and processes charged with managing these systems have not done so successfully. As a result, many of the watersheds of the Pacific coastal ecoregion no longer support natural settings for environmental processes or the valuable natural resources those processes create. An important role for scientists, educators, and decision makers is to make the integration between ecology and con sumptive uses more widely understood, as well as useful for effective management.

Download or read book Stream Ecology written by J. David Allan and published by Springer Nature. This book was released on 2021-03-17 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stream Ecology: Structure and Function of Running Waters is designed to serve as a textbook for advanced undergraduate and graduate students, and as a reference source for specialists in stream ecology and related fields. This Third Edition is thoroughly updated and expanded to incorporate significant advances in our understanding of environmental factors, biological interactions, and ecosystem processes, and how these vary with hydrological, geomorphological, and landscape setting. The broad diversity of running waters – from torrential mountain brooks, to large, lowland rivers, to great river systems whose basins occupy sub-continents – makes river ecosystems appear overwhelming complex. A central theme of this book is that although the settings are often unique, the processes at work in running waters are general and increasingly well understood. Even as our scientific understanding of stream ecosystems rapidly advances, the pressures arising from diverse human activities continue to threaten the health of rivers worldwide. This book presents vital new findings concerning human impacts, and the advances in pollution control, flow management, restoration, and conservation planning that point to practical solutions. Reviews of the first edition: ".. an unusually lucid and judicious reassessment of the state of stream ecology" Science Magazine "..provides an excellent introduction to the area for advanced undergraduates and graduate students..." Limnology & Oceanography "... a valuable reference for all those interested in the ecology of running waters."

Download or read book Dietary Effects on the Stoichiometry of Growth Regulation and Wastes of Ozark Stream Insect Detritivores written by Halvor Matthew Halvorson and published by . This book was released on 2016 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: A widespread stressor, anthropogenic nitrogen (N) and phosphorus (P) pollution can increase resource nutrient content and alter animal community composition in freshwater ecosystems. In this dissertation, I used ecological stoichiometry theory to examine effects of diet nutrient content and leaf litter type on growth, regulation, and wastes of aquatic invertebrate detritivores. I tested effects of leaf litter diet carbon:phosphorus (C:P) on growth and stoichiometric regulation of the detritivorous caddisfly Pycnopsyche lepida and used results to determine a threshold elemental ratio of oak litter C:P=1620 that confers peak growth of this species. This empirical, growth-based approach provided a more accurate estimate of the threshold elemental ratio compared to current bioenergetics models. Subsequent experiments used 33P and 14C as microbial tracers to examine effects of diet leaf type and nutrient content, as well as taxonomic identity, on incorporation efficiency of microbial C and P by the detritivorous caddisflies Pycnopsyche lepida, Lepidostoma sp., and Ironoquia sp. Results showed no effects of leaf type on incorporation efficiencies, however elevated litter P content reduced caddisfly incorporation efficiency of microbial P, and there were inverse relationships between caddisfly body C:P content and incorporation efficiencies of microbial C and P, suggesting stoichiometric links of detritivore growth rates and P requirements to reliance on litter microbial nutrients. Given the stoichiometry of growth and regulation can vary across diets and taxa to affect production and composition of animal wastes, I also examined effects of litter type and nutrient content on the stoichiometry of particulate wastes from the detritivores Pycnopsyche lepida, Lepidostoma sp., and Tipula abdominalis. Higher litter N and P content increased N and P content of particulate wastes, but the strength of effects often differed between maple and oak litter and Tipula abdominalis produced N- and P-deplete wastes compared to Pycnopsyche lepida and Lepidostoma, indicating potential taxonomically variable effects of animals on the stoichiometry of fine particulates in streams. Finally, I conducted a long-term study of C, N, and P dynamics of decomposing egesta from the detritivorous taxa Tipula sp., Lirceus sp., and Allocapnia sp. fed low- or high-P litter. Egesta from Allocapnia and Tipula decomposed faster than egesta from Lirceus, and elevated P content of egesta increased total uptake of dissolved N by egesta during decomposition. Together, my findings provide evidence that, by increasing litter nutrient content, anthropogenic nutrient pollution alters multiple species-specific functional roles of detritivorous animals in aquatic ecosystems.
