This book was released on 2012 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroinvertebrates constitute the backbone of megafaunal communities in benthic ecosystems around the globe. Many macroinvertebrates have vital roles in benthic ecosystems, ranging from enhancing habitat complexity to providing staple food sources for other organisms. Regardless of how familiar macroinvertebrates are to the general public, very few studies have attempted to describe benthic macroinvertebrate assemblages across large spatial scale in the continental shelf waters of the Pacific Northwest. This study describes different subtidal macroinvertebrate assemblages off Washington and Oregon based on species-substrata associations and the key species that distinguish one assemblage from another. Two data sets were used for this study: underwater footage collected by the submersible Delta during 1993-1995 geological surveys, and footage collected by the remotely operated vehicle (ROV) Hammerhead during macroinvertebrate surveys in late summer 2011. Footages from these surveys were used to document species-substrata associations and distinguish different assemblages based on species composition similarities and dissimilarities. In addition, I determined if a specific group of invertebrates, Asteroids (Echinodermata), were useful in explaining different assemblage patterns, after all other environmental parameters were taken into account. Findings of this study can be used not only to shed light on the structure of macroinvertebrate communities in the Pacific Northwest, but also as baseline data for future research on the direct and indirect effects of potential offshore installations on macroinvertebrate communities across the continental shelf waters.

Available in PDF, EPUB and Kindle. Book excerpt: Biodiversity is among the richest treasures of the earth. Despite their small size, microbes play a vital role in environmental monitoring and making the earth sustainable. Microorganisms preserve and assist plants and animals o either directly or indirectly, and, due to their omnipresence in nature, they inhabit conditions such as extreme temperatures, water, soil, salt, medical wastes, agricultural wastes, and air. Microbes are also important in human culture and play an essential role in existence of life. They are present in food fermentation, sewage treatment, medical, agricultural, and soil waste, antibiotics, soil fertility, model organisms, and human microbiota, aid with decomposition, and are responsible for infectious diseases. This volume represents an important contribution to the field, highlighting the importance of microbial biodiversity to society.

Available in PDF, EPUB and Kindle. Book excerpt: We conceived the idea for this book after teaching a graduate seminar on 'Habitat Complexity' at The University of South Florida. Discussions during the seminar led us to conclude that similar goals were to be found in studies of the topic that spanned the breadth of ecological research. Yet, the exact meaning of 'habitat structure', and the way in which it was measured, seemed to differ widely among subdisciplines. Our own research, which involves several sorts of ecology, convinced us that the differences among subdisciplines were indeed real ones, and that they did inhibit communica tion. We decided that interchange of ideas among researchers working in marine ecology, plant-animal interactions, physiological ecology, and other more-or-less independent fields would be worthwhile, in that it might lead to useful generalizations about 'habitat structure'. To foster this interchange of ideas. we organized a symposium to attract researchers working with a wide variety of organisms living in many habitats, but united in their interest in the topic of 'habitat structure'. The symposium was held at The University of South Florida's Chinsegut Hill Conference Center, in May. 1988. We asked participants to think about 'habitat structure' in new ways; to synthesize important, but fragmented, information; and. perhaps. to consider ways of translating ideas across systems. The chapters contained in this book reflect the participants' attempts to do so. The book is divided into four parts, by major themes that we have found useful categorizations.

Available in PDF, EPUB and Kindle. Book excerpt: Running waters are enormously diverse, ranging from torrential mountain brooks, to large lowland rivers, to great river systems whose basins occupy subcontinents. While this diversity makes river ecosystems seem overwhelmingly complex, a central theme of this volume is that the processes acting in running waters are general, although the settings are often unique. The past two decades have seen major advances in our knowledge of the ecology of streams and rivers. New paradigms have emerged, such as the river continuum and nutrient spiraling. Community ecologists have made impressive advances in documenting the occurrence of species interactions. The importance of physical processes in rivers has attracted increased attention, particularly the areas of hydrology and geomorphology, and the inter-relationships between physical and biological factors have become better understood. And as is true for every area of ecology during the closing years of the twentieth century it has become apparent that the study of streams and rivers cannot be carried out by excluding the role of human activities, nor can we ignore the urgency of the need for conservation. These developments are brought together in Stream Ecology: Structure and function of running waters, designed to serve as a text for advanced undergraduate and graduate students, and as a reference book for specialists in stream ecology and related fields.

This book was released on 2021 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Southern Green Bay, Lake Michigan is one of the most productive ecosystems in the Great Lakes and has historically been subjected to a wide range of stressors, yet little is known about the current macroinvertebrate community structure. The most recent comprehensive assessment of benthic fauna was by Markert (1982) in 1978. The objectives of this project were to describe the current macroinvertebrate community, examine changes since 1978, and identify major environmental drivers of benthic community compositions. In total, 258 stations were surveyed, including 97 that were also sampled in 1978, 100 that were added to increase spatial resolution, and 61 that were subjected to periodic hypoxia. I collected 95 macroinvertebrate taxa in southern Green Bay with the community dominated by the eurytopic midge Chironomus and immature tubificid worms. Nonmetric multidimensional scaling (NMDS) ordination and indicator analyses distinguished contemporary and historical communities and revealed shifts in benthic macroinvertebrate structure; although oligochaete worms and chironomids remained dominant over time, Chironomus abundance increased and characterized the contemporary community, whereas the benthos were historically more diverse. The magnitude of temporal change varied regionally with larger differences concentrated in southern middle bay and the inner bay remaining comparable to 1978. Contemporary assemblages are driven primarily by productivity, substrate type, and hypoxia, according to NMDS ordinations. Regular benthic monitoring should continue to evaluate biological responses to environmental stressors and assess management actions.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an unpretentious editing venture to fill the gap in our current knowledge on the ecological implications caused by anthropogenic disturbances upon benthic communities in several regions of the world, including the Western Atlantic, the Mediterranean Sea, and the Eastern Pacific Ocean, as well as the pristine environments of the Andes in South America. The common goal of the contributing authors in this book was to unravel the complex processes that make possible the life existence of bottom-living animals in different environmental scenarios. To achieve such a goal, the authors focus their attention on the emerging issues inherent to global climate change or the pollution of aquatic systems. These are all themes that might be of interest to scientists active in a wide range of oceanographic subdisciplines. Well-established researchers would appreciate the innovative approach adopted in each chapter of the book, which extends from the ecosystem level to refined molecular interpretations.

This book was released on 2012-12-06 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of the ecological integrity of running waters is a prerequisite to an understanding of the effects of human alterations. The evaluation of degradation processes provides key information on how to avoid further negative impacts. The success of future conservation, mitigation and restoration activities will rely on sound assessment methodologies and their ecological relevance and applicability. Assessment methodologies are therefore an integral part of sustainable river management. This book synthesizes and discusses state-of-the-art experiences in assessment methodologies. Including the latest knowledge on structures, processes and functions of running waters as a fundamental basis for developing adequate assessment methods, the book focuses on method development, application, and in particular on integrated assessment methods. This book is directed at scientists and managers with the aim of more effective preservation, restoration and maintenance of the ecological integrity of running water ecosystems.

Available in PDF, EPUB and Kindle. Book excerpt: Sedimentary habitats cover the vast majority of the ocean floor and constitute the largest ecosystem on Earth. These systems supply fundamental services to human beings, such as food production and nutrient recycling. It is well known that meiofauna are an abundant and ubiquitous component of sediments, even though their biodiversity and importance in marine ecosystem functioning remain to be fully investigated. In this book, the meiofaunal biodiversity trends in marine habitats worldwide are documented, along with the collection of empirical evidence on their role in ecosystem services, such as the production, consumption, and decomposition of organic matter, and energy transfer to higher and lower trophic levels. Meiofaunal activities, like feeding and bioturbation, induce changes in several physico-chemical and biological properties of sediments, and might increase the resilience of the benthic ecosystem processes that are essential for the supply of ecosystem goods and services required by humans. As a key component of marine habitats, the taxonomical and functional aspects of the meiofaunal community are also used for the ecological assessment of the sediments’ quality status, providing important information on the anthropogenic impact of benthos.
