Available in PDF, EPUB and Kindle. Book excerpt: The global concepts of sustainable development demand for scientific progress to be integrated with the realities of environmental management, legislation, and policy making. Aquatic ecosystem management is a key element in this endeavour for sustainability, since water quality is an important prerequisite for human health and development. The health and integrity of aquatic ecosystems should therefore, not only be regarded as important in its own right, but Water is Life. Freshwater is one of the most valuable commodities on our planet, and this resource should be managed in a sustainable way. Yet, we are less than careful in the way we use water and many of our non-marine, aquatic habitats are threatened by anthropogenic impacts. Eutrophication, for example, could well turn into one of the major social as well as economic problems of the 21st century. Reduction of water quality also has a profound effect on the biota that depend on these water bodies, such as micro-organisms, plants and animals. Freshwater Biodiversity is a much underestimated component of global biodiversity, both in its diversity and in its potential to act as models for fundamental research in evolutionary biology and ecosystem studies. Freshwater organisms also reflect quality of water bodies and can thus be used to monitor changes in ecosystem health. The present book deals with all of these aspects of Aquatic Biodiversity. It comprises a unique collection of primary research papers spanning a wide range of topics in aquatic biodiversity studies, and including a first global assessment of specific diversity of freshwater animals. The book also presents a section on the interaction between scientists and science policy managers. A target opinion paper lists priorities in aquatic biodiversity research for the next decade and several reactions from distinguished scientists discuss the relevance of these items from different points of view: fundamental ecology, taxonomy and systematics, needs of developing countries, present-day biodiversity policy at European and at global scales. It is believed that such a platform for the interaction between science and science policy is an absolute necessity for the efficient use of research budgets in the future.

Download or read book Restoration of Aquatic Ecosystems written by National Research Council and published by National Academies Press. This book was released on 1992-01-01 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Download or read book Fundamentals of Aquatic Ecology written by Richard Stephen Kent Barnes and published by Wiley-Blackwell. This book was released on 1991-01 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Aquatic Ecology describes the fundamental features common to all aquatic systems, both marine and freshwater. This unique synthesis allows for the discussion of ecological processes comparatively, across environments. A general introduction is followed by discussion of various 'types' of aquatic ecosystems - open waters, coastal zones, benthos, and the aquatic ecosystem as a whole. This is followed by an important new chapter on aquatic ecosystems and global ecology. Later chapters consider the individuals and communities in aquatic ecosystems and then habitat types which are peculiar to them.
Download or read book Investigating Water With Young Children Ages 3 8 written by Beth Dykstra Van Meeteren and published by Teachers College Press. This book was released on 2023 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is a meaningful context for children to engage in inquiry and acquire and use science and engineering practices, such as developing spatial thinking and early concepts of water dynamics. This book shows teachers how to engage children with opportunities to engineer water movement through pouring and filling containers of various kinds and shapes, observing how water interacts with surfaces in large and small amounts, exploring how water can be moved, and using water to move objects. These experiences build a foundation that will support children’s more complex study of this phenomena in later schooling, as well as encourage interest in STEM fields. The text provides guidance for arranging the physical, intellectual, social–emotional, and promotional environments of the early childhood classroom; for integrating literacy learning; and for building essential partnerships with administrators and families to enhance STEM learning for our youngest learners. Book Features: Introduces WaterWorks, an integrative STEM experience developed by young children, their teachers, and early childhood researchers. Describes an approach that engages children in doing science and engineering, rather than teaching children about these fields.Offers children the opportunity to engage in STEM experiences every day in their classrooms alongside literacy learning. Illustrates ways to plan and use over ten types of engineering experiences appropriate for children ages 3–8.Includes guidance for documenting children’s learning over time.Aligns to the Early Learning Outcomes Framework and the Next Generation Science Standards. Contributors: Allison Barness, Shelly L. Counsell, Lawrence Escalada, Judith Finkelstein, Linda Fitzgerald, Sherri Peterson, Jull Uhlenberg, and Wendy Miller. Praise for the STEM for Our Youngest Learners Series: “This series is an important addition to a very limited field of guides for teaching STEM to young learners. While activity books abound, this series, with its basis in constructivism and its use of an inquiry-based teaching model, guides teachers in creating in-depth experiences for children to examine the natural world while building their critical thinking skills and deepening their curiosity about and interest in the world around them.” —Karen Worth, consultant in science education, early childhood and elementary years
Download or read book Anthropogenic Pollution of Aquatic Ecosystems written by Donat-P. Häder and published by Springer Nature. This book was released on 2021-09-30 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides examples of pollutants, such as accidental oil spills and non-degradable plastic debris, which affect marine organisms of all taxa. Terrestrial runoff washes large amounts of dissolved organic materials from agriculture and industry, toxic heavy metals, pharmaceuticals, and persistent organic pollutants which end up into rivers, coastal habitats, and open waters. While this book is not intended to encyclopaedically list all kinds of pollution, it rather exemplifies the problems by concentrating on a number of serious and prominent recent developments. The chapters in this book also discuss measures to decrease and remove aquatic pollution to mitigate the stress on aquatic organisms. Aquatic ecosystems provide a wide range of ecological and economical services. In addition to providing a large share of the staple diet for a fast growing human population, oceans absorb most of the anthropogenically emitted carbon dioxide and mitigate climate change. As well as rising temperatures and ocean acidification, pollution poses increasing problems for aquatic ecosystems and organisms reducing its functioning and services which are exposed to a plethora of stress factors.
