This book presents methods for investigating the effects of aquatic environmental changes on organisms and the mechanisms involved. It focuses mainly on photosynthetic organisms, but also provides methods for virus, zooplankton and other animal studies. Also including a comprehensive overview of the current methods in the fields of aquatic physiology, ecology, biochemistry and molecular approaches, including the advantages and disadvantages of each method, the book is a valuable guide for young researchers in marine or aquatic sciences studying the physiological processes associated with chemical and physical environmental changes.
Aquatic Ecotoxicology: Advancing Tools for Dealing with Emerging Risks presents a thorough look at recent advances in aquatic ecotoxicology and their application in assessing the risk of well-known and emerging environmental contaminants. This essential reference, brought together by leading experts in the field, guides users through existing and novel approaches to environmental risk assessment, then presenting recent advances in the field of ecotoxicology, including omics-based technologies, biomarkers, and reference species. The book then demonstrates how these advances can be used to design and perform assays to discover the toxicological endpoints of emerging risks within the aquatic environment, such as nanomaterials, personal care products, PFOS and chemical mixtures. The text is an invaluable reference for any scientist who studies the effects of contaminants on organisms that live within aquatic environments. - Provides the latest perspectives on emerging toxic risks to aquatic environments, such as nanomaterials, pharmaceuticals, chemical mixtures, and perfluorooctane sulfonate (PFOS) - Offers practical guidance on recent advances to help in choosing the most appropriate toxicological assay - Presents case studies and information on a variety of reference species to help put the ecotoxicological theory into practical risk assess
A state-of-the-art review of scientific knowledge on the environmental risk of ocean discharge of produced water and advances in mitigation technologies. In offshore oil and gas operations, produced water (the water produced with oil or gas from a well) accounts for the largest waste stream (in terms of volume discharged). Its discharge is continuous during oil and gas production and typically increases in volume over the lifetime of an offshore production platform. Produced water discharge as waste into the ocean has become an environmental concern because of its potential contaminant content. Environmental risk assessments of ocean discharge of produced water have yielded different results. For example, several laboratory and field studies have shown that significant acute toxic effects cannot be detected beyond the "point of discharge" due to rapid dilution in the receiving waters. However, there is some preliminary evidence of chronic sub-lethal impacts in biota associated with the discharge of produced water from oil and gas fields within the North Sea. As the composition and concentration of potential produced water contaminants may vary from one geologic formation to another, this conference also highlights the results of recent studies in Atlantic Canada.
One of the main challenges faced by humans today is finding a balance between economic development of respective countries and sustainable utilisation of Earths resources. With the increase in the human population, demand for water resources is increasing globally. One of the challenges for water conservation in the future is the sustainability of current and future water resource allocation. Finding a balance between what is needed by humans and what is needed in the environment is an important step in the sustainability of water resources. With this in mind, sustainable utilisation of water resources, and conservation and management of aquatic ecosystems on Earth is an essential step towards the sustainable management of global water resources. This book discusses the current status of water resources on Earth and challenges water resource conservation in the first chapter. The second chapter of the book describes the physical, chemical and biological properties of water, and the biological indicators that can be used as water quality indicators. The third chapter of the book discusses how water becomes polluted, factors contributing to water pollution, as well as types and sources of water pollutants. The fourth chapter discusses the importance of water quality monitoring programmes and the methods of water quality monitoring programmes. Chapters Five and Six discuss the characteristics of lotic and lentic systems, factors affecting lotic and lentic systems and possible management options for each category. Chapter Seven discusses the aspects related to watershed management and water pollution control. The final chapter discusses agricultural and urban watershed management options, common issues related to their management, and strategies to reduce waste generation and pollution control.
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.

Conserving and restoring freshwater and marine ecosystems are priorities addressed by several European and global conservation initiatives. Many management and conservation initiatives have been put in place to support the achievement of declared national and global conservation and sustainability goals. Nonetheless, the extent to which all these initiatives can provide lasting positive effects on conservation and restoration targets is often impaired/limited by the lack of robust baseline data and systematic monitoring, which in turn are constrained by the limited number of long-term monitoring programs and limited dedicated funding. This collection underlines the importance of monitoring in times of global change and shifting baselines and the urgency of boosting conservation strategies to ensure progression towards meeting global conservation objectives. Emphasis is given also to the socio-ecological contexts and dimensions of conservation efforts, and the potential of societal engagement in monitoring practices - a key enabling factor to turn conservation initiatives into practical actions and ecosystem protection.
This condensed volume summarizes updated knowledge on the warm-monomictic subtropical Lake Kinneret, including its geophysical setting, the dynamics of physical, chemical and biological processes and the major natural and anthropogenic factors that affect this unique aquatic ecosystem. This work expands on a previous monograph on Lake Kinneret published in 1978 and capitalizes on the outcome of more than 40 years of research and monitoring activities. These were intensively integrated with lake management aimed at sustainable use for supply of drinking water, tourism, recreation and fishery. The book chapters are aimed at the limnological community, aquatic ecologists, managers of aquatic ecosystems and other professionals. It presents the geographic and geological setting, the meteorology and hydrology of the region, continues with various aspects of the pelagic and the littoral systems. Finally, the last section of the book addresses lake management, demonstrating how the accumulated knowledge was applied in order to manage this important source of freshwater. The section on the pelagic system comprises the heart of the book, addressing the major physical processes, external and internal loading, the pelagic communities (from bacteria to fish), physiological processes and the major biogeochemical cycles in the lake.
