Fundamentals of Aquatic Ecology is a completely updated and revised edition of the earlier work, Fundamentals of Aquatic Ecosystems. The new edition has been re-titled to reflect the fact that the authors found that, from the modification exercise, a completely different and new book emerged. The new edition concentrates heavily of 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. A totally re-written and rejuvenated edition of an established student text. Synthesizes both marine and freshwater ecology. Covers both ecosystem ecology and population biology. In depth consideration of man's impact on the aquatic environment.

Freshwater and Marine Ecology is an introduction to the field of aquatic ecology, integrating the conceptually and methodologically widely overlapping fields of limnology and biological oceanography. It is structured like most textbooks of general ecology, leading from more elemental entities (individuals having to cope with their environment) to increasingly overarching entities, from populations over communities and ecosystems to the biogeochemistry of the entire planet and, finally, an overview over the major human impacts on the aquatic components of the earth system. The book provides examples for all major theoretical concepts of general ecology while the usual ecology textbooks have a strong terrestrial bias and rely only on few aquatic examples. This book takes the contrasting approach, motivated by the fact the fact that life originated from aquatic systems and that surface waters cover more than 70% of the Earth’s surface. The choice of studies used as examples in Freshwater and Marine Ecology provides a balanced mix of freshwater and marine studies, of field observations, experimental and modeling studies. The readers are confronted with very recent work leading to the forefront of contemporaneous research but also with classic studies which laid the foundations of theory development in the field. Freshwater and Marine Ecology is a comprehensive text ideally serving for undergraduate courses in biological oceanography, limnology, and ecology, but also for advanced students, teachers and scientists who had limited exposure to aquatic sciences and/or ecology during their studies.

The study of aquatic ecosystems and the organisms that inhabit them are studied in the two fields of aquatic ecology and biology. An aquatic ecosystem is a combination of various biotic communities and abiotic factors. Abiotic factors include parameters of water depth, nutrient level, salinity, temperature, etc. Maintenance of normal values of these variables is essential for the continued sustainability of the diverse flora and fauna of such ecosystems. Aquatic ecosystems are primarily grouped into marine and freshwater ecosystems, along with lentic, pond, lotic and wetlands forming other smaller classes. Aquatic ecosystems are crucial for the efficient recycling of nutrients, purification of water, ground water replenishment and in the provision of habitats to aquatic life. This book provides significant information on these disciplines to help develop a good understanding of aquatic biology and ecology and their related fields. It also includes some of the vital pieces of work being conducted across the world. This book is a vital tool for all researching or studying aquatic sciences as it gives incredible insights into the emerging trends and concepts

Ecologists have long struggled to predict features of ecological systems, such as the numbers and diversity of organisms. The wide range of body sizes in ecological communities, from tiny microbes to large animals and plants, is emerging as the key to prediction. Based on the relationship between body size and features such as biological rates, the physics of water and the amount of habitat available, we may be able to understand patterns of abundance and diversity, biogeography, interactions in food webs and the impact of fishing, adding up to a potential 'periodic table' for ecology. Remarkable progress on the unravelling, describing and modelling of aquatic food webs, revealing the fundamental role of body size, makes a book emphasising marine and freshwater ecosystems particularly apt. In this 2007 book, the importance of body size is examined at a range of scales that will be of interest to professional ecologists, from students to senior researchers.

Freshwater ecosystems are under increasing pressure as human populations grow and the need for clean water intensifies. The demand for ecologists and environmental managers who are trained in basic freshwater ecology has never been greater. Students and practitioners new to the field of freshwater ecology and management need a text that provides them with an accessible introduction to the key questions while still providing sufficient background on basic scientific methods. Gerry Closs, Barbara Downes and Andrew Boulton have written a text that meets the requirements of these students. Following an introduction to scientific methodology and its application to the study of ecology, several key concepts in freshwater ecology are reviewed using a wide range of scientific studies into fundamental and applied ecological questions. Key ecological questions that are explored in a freshwater context include the role of animal dispersal and predators on freshwater community structure and the impact of pollutants and introduced species on freshwater ecosystems. This book represents the only freshwater ecology textbook that is specifically aimed at an introductory level. It will also be a useful primer for students who have not previously taken a specialized freshwater course but who require an accessible overview of the subject. General reviews on the methods of science, influence of scale, and the main features of freshwater systems. Coverage of several fundamental and applied ecological questions. A logical structure in each chapter that builds from a general observation of an ecological pattern, to an exploration of the various scientific approaches that can be used to investigate such patterns. Suggested further reading lists for each chapter.

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.

A major concern among ecologists in and outside the ASEAN region is the degradation of the environment, and the overexploitation of freshwater and marine resources. There is as yet no indication that freshwater and marine resources are being managed on a sustainable basis, and loss of wetlands, whether freshwater swamps or mangrove swamps, is a major problem in the ASEAN region. Reclamation of mangrove swamps for aquaculture and agriculture seems to be a continuous activity here and the status of marine parks should also be examined in the light of recent resort development acitivities on small islands. This volume contains numerous recommendations for the promotion of ecological studies and regional cooperation in marine, freshwater ecology and conservation, with special emphasis on the common water masses like the Strait of Malacca, Gulf of Thailand and the South China Sea.
